Abstract
Monoclonal antibodies (mAbs) have been used in the development of immunotherapies that target a variety of diseases, such as cancer, autoimmune diseases, and even viral infections; they play a key role in immunization and are expected after vaccination. However, some conditions do not promote the development of neutralizing antibodies. Production and use of mAbs, generated in biofactories, represent vast potential as aids in immunological responses when the organism cannot produce them on their own, these convey unique specificity by recognizing and targeting specific antigen. Antibodies can be defined as heterotetrametric glycoproteins of symmetric nature, and they participate as effector proteins in humoral responses. Additionally, there are different types of mAbs (murine, chimeric, humanized, human, mAbs as Antibody-drug conjugates and bispecific mAbs) discussed in the present work. When these molecules are produced in vitro as mAbs, several common techniques, such as hybridomas or phage display are used. There are several preferred cell lines that function as biofactories, for the production of mAbs, the selection of which rely on the variation of adaptability, productivity and both phenotypic and genotypic shifts. After the cell expression systems and culture techniques are used, there are diverse specialized downstream processes to achieve desired yield and isolation as well as product quality and characterization. Novel perspectives regarding these protocols represent a potential improvement for mAbs high-scale production.

Abstract
The severe acute respiratory syndrome coronavirus (SARS-CoV)-2 responsible for the global COVID-19 pandemic has caused almost 760 million confirmed cases and 7 million deaths worldwide, as of end-February 2023. Since the beginning of the first COVID-19 case, several virus variants have emerged: Alpha (B1.1.7), Beta (B135.1), Gamma (P.1), Delta (B.1.617.2) and then Omicron (B.1.1.529) and its sublineages. All variants have diversified in transmissibility, virulence, and pathogenicity. All the newly emerging SARS-CoV-2 variants appear to contain some similar mutations associated with greater "evasiveness" of the virus to immune defences. From early 2022 onward, several Omicron subvariants named BA.1, BA.2, BA.3, BA.4, and BA.5, with comparable mutation forms, have followed. After the wave of contagions caused by Omicron BA.5, a new Indian variant named Centaurus BA.2.75 and its new subvariant BA.2.75.2, a second-generation evolution of the Omicron variant BA.2, have recently been identified. From early evidence, it appears that this new variant has higher affinity for the cell entry receptor ACE-2, making it potentially able to spread very fast. According to the latest studies, the BA.2.75.2 variant may be able to evade more antibodies in the bloodstream generated by vaccination or previous infection, and it may be more resistant to antiviral and monoclonal antibody drug treatments. In this manuscript, the authors highlight and describe the latest evidences and critical issues have emerged on the new SARS-CoV-2 variants.

Abstract
Background Neutralizing antibodies cocktail (casirivimab and imdevimab) has received emergency use authorization recommendation by Food and Drug Administration (FDA) and WHO for mild-to-moderate COVID-19 infection in specific high-risk groups. Antibodies cocktail has shown promising results in preventing progression to severe disease, but the real-world experience is still evolving. Herein, we present a retrospective analysis of 22 patients who were administered the antibodies cocktail between August 2021 and March 2022 at our tertiary care center. Methods We conducted an observational retrospective analysis of clinicoradiological, inflammatory parameters, progression of the disease, and outcome among 22 mild and moderate COVID-19 patients treated with antibodies cocktail. Results The mean age was 67.7 years (SD ± 18.3) and comprised of 13 males (59%), while 9 were females (40.9%). Nine (40.9%) patients were fully vaccinated with two doses, nine (40.9%) were partially vaccinated with one dose while four patients (18.2%) were unvaccinated, and the rest were unvaccinated. Diabetes and hypertension were the commonest comorbidities; hematological and solid organ malignancies were other comorbidities. Eight patients had radiological opacities consistent with COVID-19 pneumonia and had shown significant regression in four patients after the therapy. None of our patients required supplemental oxygen or progressed to severe acute respiratory distress syndrome. All patients were discharged in a stable condition within 6 days of the therapy. Conclusions The neutralizing antibodies cocktail has shown encouraging results in our analysis in preventing progression to severe disease in patients with high-risk conditions.

Abstract
Monoclonal antibodies provide highly specific and effective therapies for the treatment of chronic diseases. These protein-based therapeutics, or drug substances, are transported in single used plastic packaging to fill finish sites. According to good manufacturing practice guidelines, each drug substance needs to be identified before manufacturing of the drug product. However, considering their complex structure, it is challenging to correctly identify therapeutic proteins in an efficient manner. Common analytical techniques for therapeutic protein identification are SDS-gel electrophoresis, enzyme linked immunosorbent assays, high performance liquid chromatography and mass spectrometry-based assays. Although effective in correctly identifying the protein therapeutic, most of these techniques need extensive sample preparation and removal of samples from their containers. This step not only risks contamination but the sample taken for the identification is destroyed and cannot be re-used. Moreover, these techniques are often time consuming, sometimes taking several days to process. Here, we address these challenges by developing a rapid and non-destructive identification technique for monoclonal antibody-based drug substances. Raman spectroscopy in combination with chemometrics were used to identify three monoclonal antibody drug substances. This study explored the impact of laser exposure, time out of refrigerator and multiple freeze thaw cycles on the stability of monoclonal antibodies. and demonstrated the potential of using Raman spectroscopy for the identification of protein-based drug substances in the biopharmaceutical industry.

Abstract
Monoclonal antibodies (mAbs) are demonstrating major success in various therapeutic areas such as oncology and the treatment of immune disorders. Over the past two decades, novel analytical methodologies allowed to address the challenges of mAbs characterization in the context of their production. However, after administration only their quantification is performed and insights regarding their structural evolution remain limited. For instance, clinical practice has recently highlighted significant inter-patient differences in mAb clearance and unexpected clinical responses, without providing alternative interpretations. Here, we report the development of a novel analytical strategy based on capillary zone electrophoresis coupled to tandem mass spectrometry (CE-MS/MS) for the simultaneous absolute quantification and structural characterization of infliximab (IFX) in human serum. CE-MS/MS quantification was validated over the range 0.4-25 µg·mL-1 corresponding to the IFX therapeutic window and achieved a LOQ of 0.22 µg·mL-1 (1.5 nM) while demonstrating outstanding specificity compared to the ELISA assay. CE-MS/MS allowed structural characterization and estimation of the relative abundance of the six major N-glycosylations expressed by IFX. In addition, the results allowed characterization and determination of the level of modification of post-translational modifications (PTMs) hotspots including deamidation of 4 asparagine and isomerization of 2 aspartate. Concerning N-glycosylation and PTMs, a new normalization strategy was developed to measure the variation of modification levels that occur strictly during the residence time of IFX in the patient's system, overcoming artefactual modifications induced by sample treatment and/or storage. The CE-MS/MS methodology was applied to the analysis of samples from patients with Crohn's disease. The data identified a gradual deamidation of a particular asparagine residue located in the complementary determining region that correlated with IFX residence time, while the evolution of IFX concentration showed significant variability among patients.

Abstract
The increasing demand for the characterization of large biomolecules such as monoclonal antibodies, double-stranded deoxyribonucleic acid (dsDNA), and virus-like particles (VLPs) is raising fundamental questions pertaining to their absorption (ingress) and escape (egress) kinetics from fully porous particles. The exact expression of their concentration profiles is derived as a function of time and radial position across a single sub-3 μm Bridge-Ethylene-Hybrid (BEHTM) Particle present in size exclusion chromatography (SEC) columns. The boundary condition at the external surface area of the particle is a rectangular concentration profile mimicking the passage of the chromatographic zone. Four different BEH Particles were considered in the calculations depending on the molecular size of the analyte: 2.0 μm 100 Å BEH Particles for small molecules, 2.0 μm 200 Å BEH Particles for monoclonal antibodies, 2.0 μm 300 Å BEH Particles for dsDNA (100 base pairs), and 2.5 μm 900 Å BEH Particles for virus-like particles (VLPs). The calculated concentration profiles of small molecules and monoclonal antibodies confirm that all BEH Particles present in the column reach quasi-instantaneously thermodynamic equilibrium with the bulk mobile phase during the passage of the chromatographic band. This is no longer the case for larger biomolecules such as dsDNA or VLPs, especially when the SEC particle is located near the column inlet and for high velocities. The kinetics of biomolecule egress is slower than its kinetics of ingress leading to pronounced peak tailing. The mean concentration of the largest biomolecules in the SEC particles remains always smaller than the maximum bulk concentration. This persistent and transient intra-particle diffusion regime has direct implications on the theoretical expressions of the observed retention factors and plate heights. Classical theories of chromatography assume uniform spatial distribution of the analyte in the particle volume: this hypothesis is not verified for the largest biomolecules. These results imply that non-porous particles or monolithic structures are the most promising stationary phases for the separation and purification of the largest biomolecules in life science.

Abstract
Monoclonal antibodies (mAbs) and the post-exposure prophylaxis (PEP) with mAbs represent a very important public health strategy against coronavirus disease 2019 (COVID-19). This study has assessed a new Anti-SARS-COV-2 mAb (SA58) Nasal Spray for PEP against COVID-19 in healthy adults aged 18 years and older within three days of exposure to a SARS-CoV-2 infected individual. Recruited participants were randomized in a ratio of 3:1 to receive SA58 or placebo. Primary endpoints were laboratory-confirmed symptomatic COVID-19 within study period. A total of 1,222 participants were randomized and dosed (SA58, n=901; placebo, n=321). Median of follow-up was 2.25 days and 2.79 days for SA58 and placebo, respectively. Adverse events occurred in 221 of 901 (25%) and 72 of 321 (22%) participants with SA58 and placebo, respectively. All adverse events were mild in severity. Laboratory-confirmed symptomatic COVID-19 developed in 7 of 824 participants (0.22 per 100 person-days) in the SA58 group vs 14 of 299 (1.17 per 100 person-days) in the placebo group, resulting in an estimated efficacy of 80.82% (95%CI 52.41%-92.27%). There were 32 SARS-CoV-2 reverse transcriptase polymerase chain reaction (RT-PCR) positives (1.04 per 100 person-days) in the SA58 group vs 32 (2.80 per 100 person-days) in the placebo group, resulting in an estimated efficacy of 61.83% (95%CI 37.50%-76.69%). A total of 21 RT-PCR positive samples were sequenced and all were the Omicron variant BF.7. In conclusion, SA58 Nasal Spray showed favorable efficacy and safety in preventing symptomatic COVID-19 or SARS-CoV-2 infection in adults who had exposure to SARS-CoV-2 within 72 hours.Trial registration: ClinicalTrials.gov identifier: NCT05667714..

Abstract
The pathological hallmark of many neurodegenerative diseases is the accumulation of characteristic proteinaceous aggregates. Parkinson's disease and dementia with Lewy bodies can be characterized as synucleinopathies due to the abnormal accumulation of the protein alpha-synuclein (α-Syn). Studies have shown amyloidogenic proteins such as α-Syn and tau can exist as polymorphic aggregates, a theory widely studied mostly in their fibrillar morphology. It is now well understood that an intermediate state of aggregates, oligomers, are the most toxic species. We have shown α-Syn, when modified by different physiological inducers, result in distinct oligomeric conformations of α-Syn. Polymorphic α-Syn oligomers exhibit distinct properties such as aggregate size, conformation, and differentially interact with tau. In this study, we confirm α-Syn oligomeric polymorphs furthermore using in-house novel α-Syn toxic conformation monoclonal antibodies (SynTCs). It is unclear the biological relevance of α-Syn oligomeric polymorphisms. Utilizing a combination of biochemical, biophysical, and cell-based assays, we characterize α-Syn oligomeric polymorphs. We found α-Syn oligomeric polymorphs exhibit distinct immunoreactivity and SynTCs exhibit differential selectivity and binding affinity for α-Syn species. Isothermal titration calorimetry experiments suggest distinct α-Syn:SynTC binding enthalpies in a species-specific manner. Additionally, we found SynTCs differentially reduce α-Syn oligomeric polymorph-mediated neurotoxicity and propagation in primary cortical neurons in a polymorph-specific manner. These studies demonstrate the biological significance of polymorphic α-Syn oligomers along with the importance of polymorph-specific antibodies that target toxic α-Syn aggregates. Monoclonal antibodies that can target the conformational heterogeneity of α-Syn oligomeric species and reduce their mediated toxicity have promising immunotherapeutic potential.

Abstract
In this work, we discuss the use of surrogate functions and a new optimization framework to create an efficient and robust computational framework for process design. Our model process is the capture chromatography unit operation for monoclonal antibody purification, an important step in biopharmaceutical manufacturing. Simulating this unit operation involves solving a system of non-linear partial differential equations, which can have high computational cost. We implemented surrogate functions to reduce the computational time and make the framework more attractive for industrial applications. This strategy yielded accurate results with a 93% decrease in processing time. Additionally, we developed a new optimization framework to reduce the number of simulations needed to generate a solution to the optimization problem. We demonstrate the performance of our new framework, which uses MATLAB built-in tools, by comparing its performance against individual optimization algorithms for problems with integer, continuous, and mixed-integer variables.

Abstract
OBJECTIVE Assessement of the responder and non-responder rate to consecutive monoclonal CGRP-antibody (CGRP-mAb) treatment, the presence of side effects, analysis of predictors of response and loss-of-effectiveness evaluation over time. METHODS We conducted a retrospective analysis including 171 patients with episodic (EM) or chronic migraine (CM), who received one, two or three different CGRP-mAbs. Non-response was defined as ≤ 50% reduction of monthly migraine days (MMDs) in EM and ≤ 30% reduction of MMDs in CM after 3 months of treatment. RESULTS 123 (71.9%) responded to the first mAb. Side effects led to treatment discontinuation in 9 (5.3%) patients. Of the 26 patients who did not respond to the first mAb or experienced a loss of efficacy over time, 11 (42.3%) responded to the second and two (28.6%) of 7 to the third monoclonal antibody. Poor response to therapy was associated with a higher monthly migraine frequency (p = 0.028), a higher number of prior preventive migraine therapies (p = 0.011) and medication overuse (p = 0.022). CONCLUSION Our findings support mAb-class switch in non-responders or in patients experiencing a loss of effectiveness. The use of a third CGRP-mAb could be beneficial for some patients.

Abstract
BACKGROUND Sotrovimab, a monoclonal antibody with efficacy against SARS-CoV-2 including certain Omicron variants, has been used in treatment of mild-moderate COVID-19. Limited data exists regarding its use in pregnant women. METHODS Electronic medical record review of pregnant COVID-19 patients treated with sotrovimab from 12/30/21 - 1/31/22 (Yale New Haven Health Hospital System [YNHHS]) was performed. Included were pregnant individuals ≥ 12 years, weighing ≥ 40 kg, with positive SARS-CoV-2 test (within 10 days). Those receiving care outside YNHHS or receiving other SARS-CoV-2 treatment were excluded. We assessed demographics, medical history, and Monoclonal Antibody Screening Score (MASS). The primary composite clinical outcome assessed included emergency department (ED) visit < 24 h, hospitalization, intensive care unit (ICU) admission, and/or death within 29 days of sotrovimab. Secondarily, adverse feto-maternal outcomes and events for neonates were assessed at birth or through the end of the study period, which was 8/15/22. RESULTS Among 22 subjects, median age was 32 years and body mass index was 27 kg/m2. 63% were Caucasian, 9% Hispanic, 14% African-American, and 9% Asian. 9% had diabetes and sickle cell disease. 5% had well-controlled HIV. 18%, 46%, and 36% received sotrovimab in trimester 1, 2, and 3, respectively. No infusion/allergic reactions occurred. MASS values were < 4. Only 12/22 (55%) received complete primary vaccination (46% mRNA-1273; 46% BNT162b2; 8% JNJ-78,436,735); none received a booster. CONCLUSIONS Pregnant COVID-19 patients receiving sotrovimab at our center tolerated it well with good clinical outcomes. Pregnancy and neonatal complications did not appear sotrovimab-related. Though a limited sample, our data helps elucidate the safety and tolerability of sotrovimab in pregnant women.

Abstract
Monoclonal antibodies (mAB) selectively target leukemia surface antigens and work by either blocking cell surface receptors or triggering the target cell's destruction. Similarly, enzyme inhibitors bind to complex molecular platforms and induce downstream mechanisms that trigger cell death. These are used in a variety of hematologic malignancies. Yet, they also elicit severe immune-mediated reactions as biological agents that require careful monitoring. Cardiovascular effects include cardiomyopathy, ventricular dysfunction, cardiac arrest, and acute coronary syndrome. While there have been scattered reviews of mAB and enzyme inhibitors, a consolidated resource regarding their cardiovascular risk profile is lacking. We provide general recommendations for initial screening and serial monitoring based on the literature.

Abstract
Atopic dermatitis (AD) is a chronic or chronically relapsing inflammatory skin disease which results from a complex, multifaceted interaction between environmental factors in genetically predisposed patients. Epidermal barrier impairment, alteration of the cutaneous microbiota, effect of external antigens, neurosensory dysfunction, and inflammatory and immune dysregulation all play a pivotal role in inducing and maintaining AD lesions. AD significantly impacts the patient's quality of life and general well-being and is often associated with anxiety and/or depressive symptoms. Classical treatment options include topical corticosteroids and calcineurin inhibitors, phototherapy, and systemic immunosuppression with oral corticosteroids, cyclosporine, methotrexate, and azathioprine in more severe cases. A turning point in facing AD was accomplished when the efficacy and safety of dupilumab, a monoclonal antibody targeting the interleukin (IL)-4 receptor α subunit, led to its approval for the treatment of moderate-to-severe or severe AD in children, adolescents, and adults. Subsequently, a more extensive understanding of AD etiology and pathogenesis has allowed the development of several topical and systemic novel therapy options. Most of these drugs are monoclonal antibodies which interfere with the type 2 inflammatory cascade, especially its key cytokines IL-4 and IL-13, or its downstream Janus kinase signaling pathway. However, considering the relevance of other subtypes of T helper (Th) cells, such as Th1 and Th22, and the important role of specific cytokines (IL-31) in generating pruritus, the horizon of potential therapeutic targets has widened extremely. In this review, we aim to present the most promising systemic agents currently under investigation and illustrate the most significant aspects of their efficacy, safety, and tolerability.

Abstract
PURPOSE Immuno-combination therapy is emerging as an effective treatment for advanced non-small cell lung carcinoma (NSCLC). However, compared to monotherapy, such as monoclonal antibodies or kinase inhibitors, whether combination therapy can enhance antitumor efficacy or alleviate side effects remains unclear. METHODS A systematic literature search was undertaken using the PubMed, Embase, Web of Science and Cochrane Central Register of Controlled Trials databases to identify eligible studies concentrating on treatment with erlotinib or erlotinib plus monoclonal antibodies in NSCLC patients published between January 2017 and June 2022. The primary outcomes included progression-free survival (PFS), overall survival (OS), response rate (RR) and treatment-related adverse events (AEs). RESULTS Seven independent randomized, controlled clinical trials including 1513 patients were obtained for the final analysis. Erlotinib plus monoclonal antibodies was significantly associated with the improvement of PFS (hazards ratio [HR], 0.60; 95% CI 0.53-0.69; z = 7.59, P < 0.01) and with moderate performance regarding OS (HR, 0.81; 95% CI 0.58-1.13; z = 1.23, P = 0.22) and RR (odds ratio [OR], 1.25; 95% CI 0.98-1.59; z = 1.80, P = 0.07), irrespective of EGFR mutation status. In the safety evaluation, erlotinib plus monoclonal antibodies had a markedly higher occurrence of adverse events (AEs) of Clavien grade 3 or higher (OR, 3.32; 95% CI 2.66-4.15; z = 10.64, P < 0.01). CONCLUSION Compared with erlotinib alone, combination therapy (erlotinib plus monoclonal antibodies) was associated with significantly improved PFS in NSCLC therapy, accompanied by increased treatment-related AEs. REGISTRATION Our systematic review protocol was registered in the PROSPERO international register of systematic reviews (CRD42022347667).

Abstract
Hand, foot and mouth disease (HFMD) is caused by a variety of serotypes in species A of the Enterovirus genus, including recently re-emerged Coxsackievirus A2 (CV-A2), CV-A4 and CV-A5. For development of diagnostic reagents, for surveillance, and the development of multivalent vaccines against HFMD, the antigenicity of HFMD-associated enteroviruses warrants investigation. The purified virions of CV-A4 were inoculated into Balb/c mice and hybridomas were obtained secreting monoclonal antibodies (mAbs) directed against CV-A4 and cross-reacting with other closely related species A enteroviruses. The mAbs were characterized by ELISA, Western blotting and in vitro neutralizing assays. The majority of mAbs was non-neutralizing, with only 2% of the mAbs neutralizing CV-A4 specifically. Most of mAbs bound to linear VP1 epitopes of CV-A4. Interestingly, four types of mAbs were obtained which bound specifically to CV-A4 or were broadly to CV-A4/-A2, CV-A4/-A5 and CV-A4/-A2/-A5, respectively. Mapping with overlapping or single-amino-acid mutant peptides revealed that the four types of mAbs all bound to the first 15 amino acids at the N-terminus of the VP1. This region of picornaviruses is functionally important as it is involved in uncoating and releasing of viral RNA into the cytosol. The binding footprints of four type mAbs are composed of conserved and variable residues and are different from each other. The newly discovered broadly cross-reactive mAbs reflect the high homology of CV-A4/ CV-A2/CV-A5. The results also demonstrate that it is possible and beneficial to develop the diagnostic reagents to detect rapidly the main pathogens of enteroviruses associated with HFMD cause by CV-A4/CV-A2/CV-A5.

Abstract
Immediate hypersensitivity reactions (IHRs) to antineoplastic agents occur frequently, and every oncologist will encounter these reactions in their clinical practice at some point. The clinical signature of IHRs can range from mild to life-threatening, and their occurrence can substantially impede the treatment course of patients with cancer. Yet, clear guidelines regarding the diagnosis and management are scarce, especially from an oncologic point of view. Therefore, herein, we review the definition, pathophysiology, epidemiology, diagnosis and management of IHRs to chemotherapeutic agents and monoclonal antibodies. First, we focus on defining the specific entities that comprise IHRs and discuss their underlying mechanisms. Then, we summarize the epidemiology for the antineoplastic agents that represent the most common causes of IHRs, i.e., platinum compounds, taxanes and monoclonal antibodies (mAbs). Next, we describe the possible clinical pictures and the comprehensive diagnostic work-up that should be executed to identify the culprit and safe alternatives for the future. Finally, we finish with reviewing the treatment options in both the acute phase and after recovery, with the aim to improve the oncologic care of patients with cancer.

Abstract
BACKGROUND The response pattern to monoclonal antibodies against calcitonin gene-related peptide (anti-CGRP MAbs) shown in migraine prevention clinical trials is not always reproducible at an individual-level. OBJECTIVE To describe patterns of start and consistency of the response to anti-CGRP MAbs during first six months of treatment and the association to baseline clinical characteristics METHODS: This is a prospective clinical cohort observational study. We included migraine patients treated with erenumab or galcanezumab evaluated at baseline and after three and six months (M3-M6) of treatment. The response was categorized according to reduction in monthly headache days (MHD): Sustained-response (SustainedR, ≥50% at M3 and M6); Short-Response (ShortR, M3≥50% and M6<50%), Later-Response (LaterR, M3<50% and M6≥50%); Limited-Response (LimitedR, 25-50% at M3 and M6) and No-Response (NoR, <25% at M3 and M6). Response patterns were compared at baseline and with outcome variables at M3 and M6. RESULTS We included 357 patients with a headache frequency of 21.0(16.0, 28.0) MHD and 84.0% (300/357) were chronic migraine. The distribution according to response pattern was: 37.0% (110/297) Sustained-Response, 16.8% (50/297) Later-Response, 10.4% (31/297) Short-Response, 22.6% (67/297) Limited-Response and 13.1% showed No-Response (39/297). Sustained-R and Later-R groups showed statistically significant anxiety and depression score reduction at M3 and M6 compared to other groups. CONCLUSION Initial response to anti-CGRP MAbs is not consistent in all patients. Persistence of anxiety and depression might be associated with lower response rates at month 6.

Abstract
INTRODUCTION Advances in the treatment of myasthenia gravis (MG) have improved quality of life and prognosis for the majority of patients. However, 10%-20% of patients present refractory MG, with frequent relapses and significant functional limitations. PATIENTS AND METHODS Patients with refractory MG were selected from a cohort of patients diagnosed with MG between January 2008 and June 2019. Refractory MG was defined as lack of response to treatment with prednisone and at least 2 immunosuppressants, inability to withdraw treatment without relapse in the last 12 months, or intolerance to treatment with severe adverse reactions. RESULTS We identified 84 patients with MG, 11 of whom (13%) met criteria for refractory MG. Mean (standard deviation) age was 47 (18) years; 64% of patients with refractory MG had early-onset generalised myasthenia (as compared to 22% in the group of patients with MG; P < .01), with a higher proportion of women in this group (P < .01). Disease severity at diagnosis and at the time of data analysis was higher among patients with refractory MG, who presented more relapses during follow-up. Logistic regression analysis revealed an independent association between refractory MG and the number of severe relapses. CONCLUSIONS The percentage of patients with refractory MG in our series (13%) is similar to those reported in previous studies; these patients were often women and presented early onset, severe forms of onset, and repeated relapses requiring hospital admission during follow-up.

Abstract
Chikungunya virus (CHIKV), a mosquito-borne alphavirus, is an emerging global threat identified in more than 60 countries across continents. The risk of CHIKV transmission is rising due to increased global interactions, year-round presence of mosquito vectors, and the ability of CHIKV to produce high host viral loads and undergo mutation. Although CHIKV disease is rarely fatal, it can progress to a chronic stage, during which patients experience severe debilitating arthritis that can last from several weeks to months or years. At present, there are no licensed vaccines or antiviral drugs for CHIKV disease, and treatment is primarily symptomatic. This Review provides an overview of CHIKV pathogenesis and explores the available therapeutic options and the most recent advances in novel therapeutic strategies against CHIKV infections.

Abstract
Although targeted immunomodulatory medications are increasingly utilized for inflammatory skin conditions like plaque psoriasis, little is known of the trends in the adoption of newly Federal Drug Administration (FDA)-approved immunomodulators by dermatologists. We performed a retrospective, cross-sectional analysis of Medicare Part D Prescriber datasets to identify dermatologists filing Medicare prescription claims for immunomodulatory drugs FDA-approved for plaque psoriasis between 2013 and 2018. Differences in dermatologist characteristics were determined between dermatologists prescribing a psoriasis treatment within two years of its FDA approval, "early adopters" and non-prescriber dermatologists over the same time period. Biologics approved for psoriasis from 2013 to 2018 included certolizumab pegol, secukinumab, brodalumab, ixekizumab, guselkumab, and apremilast. Early adopter dermatologists (n = 783) accounted for 5% of all Medicare Part D prescribing dermatologists. Early adopters were more likely to be male, in practice longer, and had a greater number of average annual beneficiaries than dermatologists who did not. Only six (< 1%) early adopters practiced in a small town or rural areas. We believe these data show that the adoption of novel biologic treatments for psoriasis by dermatologists to Medicare beneficiaries may be associated with clinician experience and practice volume. Additionally, we identified low absolute numbers of dermatologists prescribing biologics overall in non-metropolitan areas, which may represent delayed access to novel psoriasis treatments for many Medicare beneficiaries.

Abstract
Objectives Chronic rhinosinusitis with nasal polyposis (CRSwNP) is a highly prevalent and challenging disease to manage. Several systematic reviews (SRs) have been carried out to evaluate the efficacy and safety of biologic therapies. We aimed to evaluate the current and available evidence of the biologics in treating CRSwNP. Data Source Systematic Review of three electronic databases. Review Methods Following the PRISMA Statement, the authors explored three main databases through February 2020 for pertinent SRs and meta-analyses (MAs) as well as experimental and observational studies. A Measurement Tool to Assess Systematic Reviews Version-2 (AMSTAR-2), was employed to evaluate the quality of methodology of SRs and MAs. Results A Total of five SRs were included in this overview. The AMSTAR-2 final summary was moderate to critically low. Although conflicting findings were reported, anti-immunoglobulin E (Anti-IgE) and anti-interleukin-4 (Anti-IL-4) were superior to placebo for improving total nasal polyp (NP) score, particularly in patients with asthma. Findings of the included reviews revealed that both sinus opacification and the Lund-Mackay (LMK) total scores significantly improved after biologics use. Subjective quality-of-life (QoL) assessment provided by general and specific questionnaires illustrated favorable results of biologics for CRSwNP, whereas no significant adverse events were reported. Conclusion The current findings support the use of biologics for CRSwNP patients. However, the evidence for their use in such patients should be cautiously adopted because of the questionable evidence. Supplementary Information The online version contains supplementary material available at 10.1007/s12070-022-03144-8.

Abstract
Cardiac amyloidosis (CA) is an infiltrative disease caused by progressive deposition of amyloid fibres in the heart. The most common forms include immunoglobulin light-chain and transthyretin amyloidosis. Current therapies for CA either stabilize or block the production of amyloidogenic precursors, preventing further amyloid deposition. This approach, while reducing cell damage and disease progression, does not target pre-existing amyloid deposits. Conversely, amyloid removal might stimulate functional recovery of the affected organ, thus improving quality of life and survival. A therapeutic strategy based on monoclonal antibodies capable of selectively binding amyloid deposits and inducing their removal has recently been tested in various clinical trial, with promising results, and could represent a key treatment for CA in the near future.

Abstract
Meteorin-like (Metrnl) is a novel immune regulatory factor or adipokine which is mainly produced by activated macrophages. In teleost fish, two homologs are present. In this study, monoclonal antibodies were prepared against recombinant grass carp (Ctenopharyngodon idella, Ci) Metrnl-a in mice and characterized by Western blotting, flow cytometry and immunofluorescent microscopy. In grass carp infected with Aeromonus hydrophila (A. hydrophila), the cells expressing CiMetrnl-a markedly increased in the gills, head kidney and intestine. In the inflamed intestine caused by A. hydrophila infection, the CiMetrnl-a producing cells were detected mainly in the mucosal layer of anterior, middle and posterior segments. Consistently, qRT-PCR analysis showed that the mRNA expression of CiMetrnl-a was markedly induced. Our results suggest that CiMetrnl-a is involved in regulating intestine inflammation caused by bacterial infection.

Abstract
Cancer immunotherapy in the form of immune checkpoint inhibitors and cellular therapies has improved the treatment and prognosis of many patients. Nevertheless, most cancers are still resistant to currently approved cancer immunotherapies. New approaches and rational combinations are needed to overcome these resistances. There is emerging evidence that Siglec receptors could be regarded as new immune checkpoints and targets for cancer immunotherapy. In this review, we summarize the experimental evidence supporting Siglec receptors as new immune checkpoints in cancer and discuss their mechanisms of action, as well as current efforts to target Siglec receptors and their interactions with sialoglycan Siglec-ligands.

Abstract
Monoclonal antibodies (mAbs) are one of the fastest-growing classes of drugs and have been approved to treat several diseases, including cancers and autoimmune disorders. Preclinical pharmacokinetics studies are performed to determine the therapeutically meaningful dosages and efficacy of candidate drugs. These studies are typically performed in non-human primates; however, using primates is costly and raises ethical considerations. As a result, rodent models that better mimic human-like pharmacokinetics have been generated and remain an area of active investigation. Pharmacokinetic characteristics of a candidate drug, such as half-life, are partly controlled by antibody binding to the human neonatal receptor hFCRN. Due to the abnormally high binding of human antibodies to mouse FCRN, traditional laboratory rodents do not accurately model the pharmacokinetics of human mAbs. In response, humanized rodents expressing hFCRN have been generated. However, these models generally use large inserts randomly integrated into the mouse genome. Here, we report the production and characterization of a CRISPR/Cas9-mediated hFCRN transgenic mouse termed SYNB-hFCRN. Using CRISPR/Cas9-assisted gene targeting, we prepared a strain with a simultaneous knockout of mFcrn and insertion of a hFCRN mini-gene under the control of the endogenous mouse promoter. These mice are healthy and express hFCRN in the appropriate tissues and immune cell subtypes. Pharmacokinetic evaluation of human IgG and adalimumab (Humira®) demonstrate hFCRN-mediated protection. These newly generated SYNB-hFCRN mice provide another valuable animal model for use in preclinical pharmacokinetics studies during early drug development.

Abstract
BACKGROUND Respiratory syncytial virus (RSV) causes a substantial burden of acute lower respiratory infection in children under 5 years, particularly in low- and middle-income countries (LMICs). Maternal vaccine (MV) and next-generation monoclonal antibody (mAb) candidates have been shown to reduce RSV disease in infants in phase 3 clinical trials. The cost-effectiveness of these biologics has been estimated using disease burden data from global meta-analyses, but these are sensitive to the detailed age breakdown of paediatric RSV disease, for which there have previously been limited data. METHODS We use original hospital-based incidence data from South Africa (ZAF) and Kenya (KEN) collected between 2010 and 2018 of RSV-associated acute respiratory infection (ARI), influenza-like illness (ILI), and severe acute respiratory infection (SARI) as well as deaths with monthly age-stratification, supplemented with data on healthcare-seeking behaviour and costs to the healthcare system and households. We estimated the incremental cost per DALY averted (incremental cost-effectiveness ratio or ICER) of public health interventions by MV or mAb for a plausible range of prices (5-50 USD for MV, 10-125 USD for mAb), using an adjusted version of a previously published health economic model of RSV immunisation. RESULTS Our data show higher disease incidence for infants younger than 6 months of age in the case of Kenya and South Africa than suggested by earlier projections from community incidence-based meta-analyses of LMIC data. Since MV and mAb provide protection for these youngest age groups, this leads to a substantially larger reduction of disease burden and, therefore, more favourable cost-effectiveness of both interventions in both countries. Using the latest efficacy data and inferred coverage levels based on antenatal care (ANC-3) coverage (KEN: 61.7%, ZAF: 75.2%), our median estimate of the reduction in RSV-associated deaths in children under 5 years in Kenya is 10.5% (95% CI: 7.9, 13.3) for MV and 13.5% (10.7, 16.4) for mAb, while in South Africa, it is 27.4% (21.6, 32.3) and 37.9% (32.3, 43.0), respectively. Starting from a dose price of 5 USD, in Kenya, net cost (for the healthcare system) per (undiscounted) DALY averted for MV is 179 (126, 267) USD, rising to 1512 (1166, 2070) USD at 30 USD per dose; for mAb, it is 684 (543, 895) USD at 20 USD per dose and 1496 (1203, 1934) USD at 40 USD per dose. In South Africa, a MV at 5 USD per dose would be net cost-saving for the healthcare system and net cost per DALY averted is still below the ZAF's GDP per capita at 40 USD dose price (median: 2350, 95% CI: 1720, 3346). For mAb in ZAF, net cost per DALY averted is 247 (46, 510) USD at 20 USD per dose, rising to 2028 (1565, 2638) USD at 50 USD per dose and to 6481 (5364, 7959) USD at 125 USD per dose. CONCLUSIONS Incorporation of new data indicating the disease burden is highly concentrated in the first 6 months of life in two African settings suggests that interventions against RSV disease may be more cost-effective than previously estimated.

Abstract
FDA-approved anti-TNFα biopharmaceuticals are successful in treating a range of autoimmune diseases. However, not all anti-TNFα products are identical in their patient outcomes, suggesting that there may be product-specific differences stemming from protein structural differences, doses and routes of administration. In this work, we focus only on structural and functional differences across three full-length anti-TNFα mAbs (Humira®, Remicade®, and Simponi Aria®) to better understand the implications of such differences on the products' efficacy. For structural characterization, we quantified N-glycans using mass spectrometry and fluorescence labeling. From these studies, we observed that Remicade® had the highest percent of afucosylated glycans (15.5 ± 1.3 %) and the largest number of unique glycans, 28. While Humira® had the fewest unique glycans, 15, and 11.4 ± 0.8 % of afucosylated, high-mannose glycans. For the functional studies we tested TNFα binding via ELISA, FcγRIIIa binding via AlphaLISA and effector function using an ADCC bioreporter assay. Humira® had a significantly lower EC50 (1.9 ± 0.1 pM) for ELISA and IC50 (10.5 ± 1.1 nM) for AlphaLISA, suggesting that Humira® has higher TNFα and FcγRIIIa binding affinity than Remicade® and Simponi Aria®. Humira® was also the most potent in the bioreporter assay with an EC50 value of 0.55 ± 0.03 nM compared to Remicade® (0.64 ± 0.04 nM) and Simponi Aria® (0.67 ± 0.03 nM). This comparison is significant as it highlights functional differences between mAbs with shared mechanisms of action when examined in a single laboratory and under one set of conditions.

Abstract
INTRODUCTION Vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), including administration of booster doses, continues to be the most effective method for controlling COVID-19-related complications including progression to severe illness and death.However, there is mounting evidence that more needs to be done to protect individuals with compromised immune function. AREAS COVERED Here, we review the effectiveness of COVID-19 vaccination in immunocompromised patients, including those with primary immunodeficiencies, HIV, cancer (including hematological malignancies), solid organ transplant recipients and chronic kidney disease, as reported in systematic reviews/meta-analyses published over a 12-month period in PubMed. Given the varied responses to vaccination patients with compromised immune function, a major goal of this analysis was to try to identify specific risk-factors related to vaccine failure. EXPERT OPINION COVID-19 remains a global problem, with new variants of concern emerging at regular intervals. There is an ongoing need for optimal vaccine strategies to combat the pandemic. In addition, alternative treatment approaches are needed for immunocompromised patients who may not mount an adequate immune response to current COVID-19 vaccines. Identification of high-risk patients, and the introduction of newer antiviral approaches such as monoclonal antibodies, will offer physicians therapeutic options for such vulnerable individuals.

Abstract
BACKGROUND Blood measurement of cardiac troponin T (cTnT) is one of the most widespread methods of acute myocardial infarction (MI) diagnosis. cTnT degradation may have a significant influence on the precision of cTnT immunodetection; however, there are no consistent data describing the level and sites of cTnT proteolysis in the blood of MI patients. In this study, we bordered major cTnT fragments and quantified their relative abundance in the blood at different times after MI. METHODS Serial heparin plasma samples were collected from 37 MI patients 2-37 h following the onset of MI. cTnT and its fragments were studied by western blotting and immunofluorescence analysis using monoclonal antibodies specific to various cTnT epitopes. RESULTS cTnT was present in the blood of MI patients as 23 proteolytic fragments with an apparent molecular mass of ∼ 8-37 kDa. Two major sites of cTnT degradation were identified: between amino acid residues (aar) 68 and 69 and between aar 189 and 223. Analysis of the abundance of cTnT fragments showed an increase in the fraction of free central fragments in the first few hours after MI, while the fraction of the C-terminal fragments of cTnT remained almost unchanged. CONCLUSION cTnT progressively degrades after MI and appears in the blood as a mixture of 23 proteolytic fragments. The cTnT region approximately bordered by aar 69-158 is a promising target for antibodies used for measurement of total cTnT.

Abstract
In order to predict how mAbs partition in 20% ethylene oxide/80% propylene oxide (v/v) random copolymer (EO20PO80)/water aqueous two-phase system (ATPS), a molecular dynamic simulation model was developed using Gromacs and then validated by experiments. The ATPS was applied with seven kinds of salt, including buffer salt and strong dissociation salt that were commonly employed in the purification of protein. Na2SO4 was shown to have the best effects on lowering EO20PO80 content in the aqueous phase and enhancing recovery. The content of EO20PO80 in the sample solution was decreased to 0.62%±0.25% and the recovery of rituximab increased to 97.88%±0.95% by adding 300 mM Na2SO4 into back extraction ATPS. The viability determined by ELISA was 95.57% at the same time. A strategy for constructing a prediction model for the distribution of mAbs in ATPS was proposed in consideration of this finding. Partition of trastuzumab in ATPS was predicted by the model created using this method and the prediction result was further validated by experiments. The recovery of trastuzumab reached 95.63%±2.86% under the ideal extraction conditions suggested by the prediction model.

Abstract
Despite ongoing debate, the amyloid β-protein (Aβ) remains the prime therapeutic target for the treatment of Alzheimer's disease (AD). However, rational drug design has been hampered by a lack of knowledge about neuroactive Aβ. To help address this deficit, we developed live-cell imaging of iPSC-derived human neurons (iNs) to study the effects of the most disease relevant form of Aβ-oligomeric assemblies (oAβ) extracted from AD brain. Of ten brains studied, extracts from nine caused neuritotoxicity, and in eight cases this was abrogated by Aβ immunodepletion. Here we show that activity in this bioassay agrees relatively well with disruption of hippocampal long-term potentiation, a correlate of learning and memory, and that measurement of neurotoxic oAβ can be obscured by more abundant non-toxic forms of Aβ. These findings indicate that the development of novel Aβ targeting therapeutics may benefit from unbiased activity-based discovery. To test this principle, we directly compared 5 clinical antibodies (aducanumab, bapineuzumab, BAN2401, gantenerumab, and SAR228810) together with an in-house aggregate-preferring antibody (1C22) and established relative EC50s in protecting human neurons from human Aβ. The results yielded objective numerical data on the potency of each antibody in neutralizing human oAβ neuritotoxicity. Their relative efficacies in this morphological assay were paralleled by their functional ability to rescue oAβ-induced inhibition of hippocampal synaptic plasticity. This novel paradigm provides an unbiased, all-human system for selecting candidate antibodies for advancement to human immunotherapy.

Abstract
No disease-modifying therapies are currently available for Alzheimer's disease (AD) in Europe. Current evidence from clinical trials testing anti-beta amyloid (Aβ) monoclonal antibodies (mAbs) in patients with early AD, though, suggests a likely marketing authorization in the next years. Since the implementation of disease-modifying therapies for AD in the clinical practice will evidently require a huge change of dementia care in all countries, a group of prominent AD clinical experts in Italy met to discuss patients' selection and management strategies. The current diagnostic-therapeutic standard of care in Italy was taken as the starting point. The prescription of new therapies cannot ignore the definition of a biological diagnosis through the assessment of both amyloid- and tau-related biomarkers. The high risk/benefit ratio of anti-Aβ immunotherapies, moreover, needs a highly specialized diagnostic work-up and a thorough exclusion criteria assessment, which should be provided by a neurology specialist. The Expert Panel also suggests a reorganization of the Centers for dementia and cognitive decline in Italy into 3 levels of increasing complexity: community center, first- and second-level center. Tasks and requirements for each level were defined. Finally, specific characteristics of a center deputed to prescribe anti-Aβ mAbs were discussed.

Abstract
INTRODUCTION Migraine usually ameliorates after menopause. However, 10-29% of women still experience migraine attacks after menopause, especially if menopause is surgical. The use of monoclonal antibodies against the calcitonin gene-related peptide (CGRP) is changing the landscape of migraine treatment. This study aims to explore the effectiveness and safety of anti-CGRP monoclonal antibodies in women in menopause. METHODS Women affected by either migraine or chronic migraine and treated with an anti-CGRP monoclonal antibody for up to 1 year. Visits were scheduled every 3 months. RESULTS Women in menopause displayed a similar response compared to women of childbearing age. Among women in menopause, the women experiencing surgical menopause seemed to exhibit a similar response compared to the ones experiencing physiological menopause. Erenumab and galcanezumab displayed similar effectiveness in women in menopause. No serious adverse events were registered. DISCUSSION The effectiveness of anti-CGRP monoclonal antibodies is almost the same between women in menopause and women of childbearing age, without appreciable differences between the different antibodies.

Abstract
SARS-CoV-2 emerged in December 2019 and led to the COVID-19 pandemic. Efforts to develop therapeutics have led to innovations such as mRNA vaccines and oral antivirals. Here we provide a narrative review of the biologic therapeutics used or proposed to treat COVID-19 during the last 3 years. This paper, along with its companion that covers xenobiotics and alternative remedies, is an update to our 2020 paper. Monoclonal antibodies prevent progression to severe disease, are not equally effective across variants, and are associated with minimal and self-limited reactions. Convalescent plasma has side effects like monoclonal antibodies, but with more infusion reactions and less efficacy. Vaccines prevent progression for a larger part of the population. DNA and mRNA vaccines are more effective than protein or inactivated virus vaccines. After mRNA vaccines, young men are more likely to have myocarditis in the subsequent 7 days. After DNA vaccines, those aged 30-50 are very slightly more likely to have thrombotic disease. To all vaccines we discuss, women are slightly more likely to have an anaphylactic reaction than men, but the absolute risk is small.

Abstract
Monoclonal antibodies (MAs) are increasingly used in the therapeutic arsenal. Clinical Data Warehouses (CDWs) offer unprecedented opportunities for research on real-word data. The objective of this work is to develop a knowledge organization system on MAs for therapeutic use (MATUs) applicable in Europe to query CDWs from a multi-terminology server (HeTOP). After expert consensus, three main health thesauri were selected: the MeSH thesaurus, the National Cancer Institute thesaurus (NCIt) and the SNOMED CT. These thesauri contain 1,723 MAs concepts, but only 99 (5.7 %) are identified as MATUs. The knowledge organisation system proposed in this article is a six-level hierarchical system according to their main therapeutic target. It includes 193 different concepts organised in a cross lingual terminology server, which will allow the inclusion of semantic extensions. Ninety nine (51.3 %) MATUs concepts and 94 (48.7 %) hierarchical concepts composed the knowledge organisation system. Two separates groups (an expert group and a validation group) carried out the selection, creation and validation processes. Queries identify, for unstructured data, 83 out of 99 (83.8 %) MATUs corresponding to 45,262 patients, 347,035 hospital stays and 427,544 health documents, and for structured data, 61 out of 99 (61.6 %) MATUs corresponding to 9,218 patients, 59,643 hospital stays and 104,737 hospital prescriptions. The volume of data in the CDW demonstrated the potential for using these data in clinical research, although not all MATUs are present in the CDW (16 missing for unstructured data and 38 for structured data). The knowledge organisation system proposed here improves the understanding of MATUs, the quality of queries and helps clinical researchers retrieve relevant medical information. The use of this model in CDW allows for the rapid identification of a large number of patients and health documents, either directly by a MATU of interest (e.g. Rituximab) but also by searching for parent concepts (e.g. Anti-CD20 Monoclonal Antibody).

Abstract
Hypereosinophilic syndromes (HES) encompass a wide range of disorders characterized by persistent peripheral blood hypereosinophilia (HE) (i.e., an eosinophil count ≥1.5 × 109/L and ≥ 10% eosinophils preferably with a minimal duration of 6 months if documentation is available) associated with organ damage and/or dysfunction attributable to tissue eosinophilic infiltrate and release of granule contents. In most cases, HE is associated with atopic conditions/allergies, parasitic infections, medications, autoimmune disorders and/or solid tumors in most cases. More rarely, it can be one of the dominant manifestations of an underlying myeloid/lymphoid neoplasm. With regard to hematological forms, in recent decades the advances in understanding the pathogenic aspects of HES have led to a growing interest in these diseases, and in the 2016 WHO classification multiple subgroups were defined according to the molecular profile with the aim of better characterizing these syndromes and establishing which patients will benefit from specific pharmacological targeted therapies. This review article will provide a comprehensive overview of possible therapeutic approaches for HES in the light of each specific molecular alteration, considering both tyrosine kinase inhibitors and monoclonal antibodies, either implemented in clinical practice or currently still under development.

Abstract
In recent years, the role of interleukin-17 (IL-17) in orchestrating and manipulating proinflammatory immune responses has received special attention. It has become apparent from murine studies and clinical trials that due to its inhibitory effect on immunoregulation and its stimulatory action on promoting proinflammatory responses, IL-17 is an ideal cytokine to target for drug development, in order to cease its induction or eliminate IL-17-producing cells of any kind. Several monoclonal antibodies have been developed and tested as potent inhibitors of IL-17 in various inflammatory diseases. This review summarizes data from relevant clinical trials on recent developments of the application of inhibitors of IL-17 in psoriasis and psoriatic arthritis, namely secukinumab, ixekizumab, bimekizumab and brodalumab.

Abstract
Targeted therapy and precision oncology aim to improve efficacy and minimize side effects by targeting specific molecules involved in cancer growth and spread. With the advancements in genomics, proteomics, and transcriptomics with the accessible modalities such as next-generation sequencing, circulating tumor cells, and tumor Deoxyribonucleic Acid (DNA), more number of patients are being offered the targeted therapy in form of monoclonal antibodies and various intracellular targets, specific for their tumor. The harnessing of host immunity against the cancer cells by utilizing immune-oncology agents and chimeric antigen receptor T-cell therapy has further revolutionized the management of various cancers. These agents, however, have the challenge of managing the adverse effects that are peculiar to the class of drugs and very different from the conventional chemotherapy. This review article discusses the molecular basis, diagnostics, and use of targeted therapy in oncology.

Abstract
Background Post-translational modifications in bioprocessing and storage of recombinant mAbs are the main sources of charge variants. While the profile of these kinds of variants is considered an important attribute for the therapeutic mAbs, there is controversy about their direct role in safety and efficacy. In this study, the physicochemical and pharmacokinetic (PK) properties of the separated charge variants belonging to a trastuzumab potential biosimilar, were examined. Methods The acidic peaks, basic peaks, and main variants of trastuzumab were separated and enriched by semi-preparative weak cation exchange. A panel of analytical techniques was utilized to characterize the physicochemical properties of these variants. The binding affinity to HER2 and FcγRs and the PK parameters were evaluated for each variant. Results Based on the results, the charge variants of the proposed biosimilar had no significant influence on the examined efficacy and PK parameters. Conclusion During the development and production of biosimilar monoclonal antibodies, evaluating the effect of their charge variants on efficacy and PK parameters is needed.

Abstract
BACKGROUND Tixagevimab-cilgavimab is used for pre-exposure prophylaxis of COVID-19 in immunocompromised patients, though in vitro data has shown reduced neutralizing activity against SARS-CoV-2 Omicron subvariants. METHODS We performed genomic sequencing of SARS-CoV-2 isolated from patients diagnosed with COVID-19 following tixagevimab-cilgavimab. Resistance-associated substitutions were used to generate a predicted phenotypic susceptibility analysis to tixagevimab-cilgavimab and bebtelovimab. Clinical data collected from these patients included SARS-CoV-2 immunization status, COVID-19-directed therapies, and outcomes. RESULTS SARS-CoV-2 genome sequencing was performed in 25 patients. SARS-CoV-2 Omicron BA.2 was the most common identified subvariant. All patients had viral isolates with spike codon substitutions associated with reduced susceptibility to tixagevimab-cilgavimab; their predicted phenotypic analysis showed a >2-fold reduced susceptibility to tixagevimab-cilgavimab. Two patients had viral isolates with spike codon substitutions (K444N and G446D) associated with highly reduced susceptibility to bebtelovimab, although all the viral isolates had <2-fold reduced susceptibility based on predicted phenotypic analysis. Sixteen patients received rescue therapy with bebtelovimab, but one patient with BA.2 subvariant harboring K444N mutation died of COVID-19-related complications. Five patients received other COVID-19 therapies and survived. Four had mild or asymptomatic COVID-19 with an uncomplicated course despite not receiving any additional therapy. DISCUSSION Multiple SARS-CoV-2 Omicron spike codon substitutions that correlated with reduced susceptibility to tixagevimab-cilgavimab were identified in patients with COVID-19 after receiving this monoclonal antibody. Most patients had an uncomplicated course. The identification of spike codon substitutions conferring resistance to bebtelovimab highlights the importance of performing genomic surveillance to identify new resistant SARS-CoV-2 variants.

Abstract
INTRODUCTION The substantial acceleration in healthcare spending together with the expenditures to manage the COVID19 pandemic demand drug delivery solutions that enable a flexible care setting for high-dose monoclonal antibodies (mAbs) in oncology. AREAS COVERED This expert opinion introduces an analogue-based framework applied to guide decision-making for associated product improvements for mAb medications that are either already authorized or in late-stage clinical development. The four pillars of this framework comprise (1) the drug delivery profile of current and emerging treatments in the market, (2) the needs and preferences of people treated with mAbs, (3) existing healthcare infrastructures, and (4) country-dependent reimbursement and procurement models. The following product optimization examples for mAb-based treatments are evaluated based on original research and review articles in the field: subcutaneous formulations, an established drug delivery modality to reduce parenteral dosing complexity, fixed-dose combinations, an emerging concept to complement combination therapy, and (connected) on-body delivery systems, an identified future opportunity to support dosing outside of a controlled healthcare institutional environment. EXPERT OPINION Leveraging existing synergies and learnings from other disease areas is a measure to reduce associated development and commercialization costs and thus to provide sustainable product offerings already at the initial launch of a medication.

Abstract
CONTEXT AND OBJECTIVES The present study examined the perspectives of healthcare providers (HCPs) in designing a multi-disciplinary model of supportive cancer care for the relief of dermatology-related symptoms caused by monoclonal antibody therapies. METHODS The study employed a mixed research methodology, with qualitative research embedded within a pragmatic prospective study of a registry protocol study. Patients undergoing oncology therapy with MoAB, anti-HER2, and anti-PD-L1 monoclonal antibodies were identified among a cohort of patients referred to an integrative oncology (IO) consultation for symptom relief and improved quality of life (QoL). Case studies with significant dermatology-related concerns were selected and presented to a panel of 6 HCPs trained in medical oncology, oncology nursing, family medicine, supportive cancer care, and IO. HCP narratives were qualitatively analyzed and assessed using ATLAS.Ti software for systematic coding. RESULTS Of the 924 patients referred to the IO consultation, 208 were treated with monoclonal antibodies, from which 50 were selected for further evaluation. Of these, 7 cases were presented to the HCP team who were asked to identify treatment gaps requiring a multi-disciplinary approach. Qualitative analysis identified 3 major themes: a biophysical perspective; a psycho-social-spiritual perspective; and the implementation of integrated care. DISCUSSION There is a need for a multi-disciplinary approach when treating patients suffering from monoclonal antibody treatment-related skin toxicities. HCP-reported themes highlight the need to identify patients for whom such an approach is warranted; conditions in which a psycho-social-spiritual perspective should be considered, in addition to a bio-physical approach; and considerations of who should be designated as the patient's primary case manager.

Abstract
BACKGROUND Monoclonal antibody (mAb) treatment for COVID-19 is associated with improved clinical outcomes. However, there is limited information regarding the impact of treatment on symptoms and the prevalence of post-COVID Conditions (PCC). Understanding of the association between time to mAb infusion and the development of PCC is also limited. METHODS This longitudinal study was conducted among patients with COVID-19 who received mAb infusions at a Federally Qualified Health Center in San Diego, CA. A series of telephone interviews were conducted at baseline and follow-up (14 days and 28+ days). A comprehensive symptom inventory was completed and physical and mental health status were measured using PROMIS-29 and PHQ-2. Pearson's Chi-squared tests and independent two-sample t-tests were performed to test for association between time to mAb infusion and outcomes at follow-up. A Poisson regression model was used to analyze whether time to mAb infusion predicts risk of developing PCC. RESULTS Participants (N = 411) were 53% female, ranged in age from 16 to 92 years (mean 50), and a majority (56%) were Latino/Hispanic. Cross-sectional findings revealed a high symptom burden at baseline (70% of patients had cough, 50% had fever, and 44% had headache). The prevalence of many symptoms decreased substantially by the final follow-up survey (29% of patients had cough, 3% had fever, and 28% had headache). Longitudinal findings indicated that 10 symptoms decreased in prevalence from baseline to final follow-up, 2 remained the same, and 14 increased. The severity of symptoms and most patient-reported physical and mental health measure scores decreased over time. The prevalence of PCC was 69% when PCC was defined as ≥ 1 symptom at final follow-up. Time to mAb infusion was not significantly associated with any outcome at follow-up. Time to infusion was not associated with PCC status at final follow-up in the crude or adjusted Poisson regression models. CONCLUSIONS The prevalence of PCC was high among this patient population following COVID-19 mAb treatment. Time to mAb infusion did not predict the development of PCC. Further research in these areas is essential to answer urgent clinical questions about effective treatments of COVID-19.

Abstract
AIMS Proprotein convertase subtilisin/kexin-type 9 inhibitor (PCSK9i) treatment reduces cardiovascular events when taken over a long time for secondary prevention. Data on treatment adherence are scarce and maybe affected by co-payment of patients. The aim of this study was to elucidate PCSK9i treatment adherence in a setting of full cost coverage as it is the case in a number of European countries. METHODS AND RESULTS Baseline data and prescription patterns of all 7302 patients with PCSK9i prescriptions dispensed on the account of Austrian Social Insurances between September 2015 and December 2020 were retrieved and analyzed. A gap of ≥ 60 days between prescriptions was defined as treatment discontinuation. Patient adherence was evaluated as the proportion of days covered (PDC) over the observation period and treatment discontinuation rates were investigated by the Kaplan-Meier method. The mean PDC was 81.8% and was significantly lower in female patients. A PDC of ≥ 80% indicating adequate adherence was found in 73.8%. Of the study population 27.4% discontinued PCSK9i treatment and 49.2% thereof re-initiated treatment during the observation period. Most of the patients who discontinued treatment did so within the first year. Male patients and patients under 64 years showed significantly lower discontinuation and higher re-initiation rates. CONCLUSION Considering the high PDC and low discontinuation rates, the majority of patients adhere to PCSK9i treatment. Hence, in a system where PCSK9i treatment is made available at virtually no costs for patients this highly effective treatment is well-accepted as a long-term treatment.

Abstract
Purpose of Review The landscape of the coronavirus disease 2019 (COVID-19) pandemic has rapidly changed over the past 3 years. Paralleling this evolution, the scientific and medical communities have reported many novel findings relating to the infection's epidemiology, transmission, diagnosis, and treatment. We review pertinent studies of COVID-19 therapeutics with an emphasis on their application to lung transplant recipients. Recent Findings Agents that have been well-studied for treating COVID-19 include antivirals (remdesivir, nirmatrelvir/ritonavir, molnupiravir), monoclonal antibodies, and immunomodulators (for example, corticosteroids and tocilizumab). Summary Remdesivir remains an essential therapy for managing mild-moderate COVID-19. Though highly efficacious for mild-moderate COVID-19 for outpatient therapy, ritonavir-boosted nirmatrelvir has limited use in lung transplant recipients due to significant drug-drug interactions. Monoclonal antibodies, though useful, are the most affected by the emergence of new viral variants.

Abstract
When the omicron variant became the most dominant severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) variant causing coronavirus disease 2019 (COVID-19) in Japan, 11 patients with hematological diseases infected with this new variant were treated at our institution. Among them, four of the five patients who had been treated with chemotherapy progressed to moderate-II COVID-19, and two of them died. In contrast, five of the six patients who did not receive the treatment remained at mild to moderate-I stage of COVID-19, except for a single case progressing to moderate-II COVID-19. While all four patients infused with anti-coronavirus monoclonal antibodies within 8 days after the onset survived, the other two patients, being withheld from treatment or treated later, died. In these two cases, anti-SARS-Cov-2 immunoglobulin G antibodies remained at low titers. Although the omicron variant is considered a less harmful SARS-Cov-2 variant, patients with hematological disorders, particularly those who are immunosuppressed caused by chemotherapy, should be continuously cared for as they remain at a higher risk of severe COVID-19 due to insufficient or delayed anti-viral humoral immunity development. Thus, the rapid introduction of antiviral monoclonal antibodies together with anti-viral reagents may rescue these patients.

Abstract
Since the first commercial imaged capillary isoelectric focusing (icIEF) instrument was developed twenty years ago, the technology has become the gold standard of quality and manufacturing process control in the biopharmaceutical industry. This is owing to its high-resolution and high-throughput characterization of protein charge heterogeneity. In addition to a charge variant profiling, mass spectrometry (MS) analyses are also desirable to obtain an in-tact molecular weight (MW) and further identification of these charged species. While offline fractionation technologies including isoelectric focusing (IEF) and free flow electrophoresis (FFE) followed by liquid chromatography (LC)-mass spectrometry (MS) coupling have been employed for this purpose, there have been much fewer reported applications of icIEF-based MS connection and fraction collection. Factors that have impeded the development of these icIEF applications include difficulties with a direct connection to the MS interface as well as high background signal of carrier ampholytes and incompatible coated capillary cartridges. In this work, we developed a robust and flexible icIEF-MS platform which overcomes these challenges to achieve both the rapid icIEF separation and high-resolution MS (HRMS) identification of protein charged variants simultaneously. We demonstrate how this methodology proves highly-sensitive and highly reliable for the characterization of commercial monoclonal antibodies (mAbs) and antibody-drug-conjugates (ADCs). The whole workflow of icIEF-MS for protein heterogeneity is straight forward and accurate and can be performed within 45 min. Furthermore, the developed icIEF-MS configuration can flexibly switch to icIEF-based fraction collection model allowing the user to perform additional in-depth characterization such as peptide mapping by high performance liquid chromatography (HPLC) tandem mass spectrometry (LC-MS/MS).

Systematic review of MCDM approach applied to the medical case studies of COVID-19: trends, bibliographic analysis, challenges, motivations, recommendations, and future directions. COMPLEX INTELL SYST 2023; 9:1-27.

Abstract
When COVID-19 spread in China in December 2019, thousands of studies have focused on this pandemic. Each presents a unique perspective that reflects the pandemic's main scientific disciplines. For example, social scientists are concerned with reducing the psychological impact on the human mental state especially during lockdown periods. Computer scientists focus on establishing fast and accurate computerized tools to assist in diagnosing, preventing, and recovering from the disease. Medical scientists and doctors, or the frontliners, are the main heroes who received, treated, and worked with the millions of cases at the expense of their own health. Some of them have continued to work even at the expense of their lives. All these studies enforce the multidisciplinary work where scientists from different academic disciplines (social, environmental, technological, etc.) join forces to produce research for beneficial outcomes during the crisis. One of the many branches is computer science along with its various technologies, including artificial intelligence, Internet of Things, big data, decision support systems (DSS), and many more. Among the most notable DSS utilization is those related to multicriterion decision making (MCDM), which is applied in various applications and across many contexts, including business, social, technological and medical. Owing to its importance in developing proper decision regimens and prevention strategies with precise judgment, it is deemed a noteworthy topic of extensive exploration, especially in the context of COVID-19-related medical applications. The present study is a comprehensive review of COVID-19-related medical case studies with MCDM using a systematic review protocol. PRISMA methodology is utilized to obtain a final set of (n = 35) articles from four major scientific databases (ScienceDirect, IEEE Xplore, Scopus, and Web of Science). The final set of articles is categorized into taxonomy comprising five groups: (1) diagnosis (n = 6), (2) safety (n = 11), (3) hospital (n = 8), (4) treatment (n = 4), and (5) review (n = 3). A bibliographic analysis is also presented on the basis of annual scientific production, country scientific production, co-occurrence, and co-authorship. A comprehensive discussion is also presented to discuss the main challenges, motivations, and recommendations in using MCDM research in COVID-19-related medial case studies. Lastly, we identify critical research gaps with their corresponding solutions and detailed methodologies to serve as a guide for future directions. In conclusion, MCDM can be utilized in the medical field effectively to optimize the resources and make the best choices particularly during pandemics and natural disasters.
