Abstract
Subcutaneous (s.c.) administration of monoclonal antibodies (mAbs) can reduce treatment burden for patients and healthcare systems compared with intravenous (i.v.) infusion through shorter administration times, made possible by convenient, patient-centric devices. A deeper understanding of clinical pharmacology principles related to efficacy and safety of s.c.-administered mAbs over the past decade has streamlined s.c. product development. This review presents learnings from key constituents of the s.c. mAb development pathway, including pharmacology, administration variables, immunogenicity, and delivery devices. Restricted mAb transportation through the hypodermis explains their incomplete absorption at a relatively slow rate (pharmacokinetic (PK)) and may impact mAb-cellular interactions and/or onset and magnitude of physiological responses (pharmacodynamic). Injection volumes, formulation, rate and site of injection, and needle attributes may affect PKs and the occurrence/severity of adverse events like injection-site reactions or pain, with important consequences for treatment adherence. A review of immunogenicity data for numerous compounds reveals that incidence of anti-drug antibodies (ADAs) is generally comparable across i.v. and s.c. routes, and complementary factors including response magnitude (ADA titer), persistence over time, and neutralizing antibody presence are needed to assess clinical impact. Finally, four case studies showcase how s.c. biologics have been clinically developed: (i) by implementation of i.v./s.c. bridging strategies to streamline PD-1/PD-L1 inhibitor development, (ii) through co-development with i.v. presentations for anti-severe acute respiratory syndrome-coronavirus 2 antibodies to support rapid deployment of both formulations, (iii) as the lead route for bispecific T cell engagers (BTCEs) to mitigate BTCE-mediated cytokine release syndrome, and (iv) for pediatric patients in the case of dupilumab.

Abstract
INTRODUCTION Cancer imposes a high economic burden with medical care and medication costs. We evaluate the costs, the use of resources, the administration time, and the patient preferences associated with the use of biotechnological drugs in SC and IV presentations. METHODOLOGY A systematic literature search was conducted in PubMed, Embase, and seven additional databases. The search was carried out in September 2021 and included only studies directly comparing SC and IV presentations. Evidence was synthesized narratively. RESULTS 34 references were included, which only analyzed bortezomib, daratumumab, rituximab, and trastuzumab. Reduction in preparation costs of SC compared to IV presentations ranged from 6.6% to 50.1%, and in administration costs from 4.5% to 95.3%. SC administration of rituximab and trastuzumab resulted in less productivity loss. More than 68% of patients reported greater satisfaction with the SC route. A reduction of time in the infusion chair, lower costs of resources for preparation, and health personnel for the administration process were identified with SC administration. CONCLUSIONS The use of SC daratumumab, rituximab, and trastuzumab in patients with cancer reduces direct and indirect costs and adverse events compared to IV use. Patients prefer the SC administration, perceiving more comfort, and less pain at the administration site.

Preventive effect of dexamethasone premedication on the development of infusion-related reaction in breast cancer patients receiving trastuzumab. Br J Clin Pharmacol 2023; 89:2102-2112. [PMID: 36709967 DOI: 10.1111/bcp.15675] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Revised: 12/14/2022] [Accepted: 01/17/2023] [Indexed: 01/31/2023] Open
Abstract
AIM To clarify the incidence and risk factors of infusion-related reactions (IRRs) caused by trastuzumab in breast cancer patients and verify the preventive effects of dexamethasone. METHODS All breast cancer patients newly treated with trastuzumab at the Osaka Medical and Pharmaceutical University Hospital from 1 January 2017 to 31 December 2020 were included. The electronic medical records were retrospectively reviewed. The outcome measure was the occurrence of IRRs of grade 1 or higher during trastuzumab infusion. Only dexamethasone and anticancer drugs administered concomitantly before trastuzumab were used as explanatory variables. RESULTS The 176 patients included in the study received 2320 infusions. Fifty-eight patients (33.0%) experienced IRRs, and IRRs occurred in 80 (3.4%) of the total 2320 infusions. Owing to the hierarchical structure of the data, the independence of the observed values was evaluated using the intraclass correlation coefficient. Multivariate multilevel logistic regression analysis showed that premedication with dexamethasone lowered the risk of trastuzumab-induced IRRs (mg, per 1 unit, odds ratio [OR] = 0.61, 95% confidence interval [95% CI] 0.43-0.85, P = .003). In addition, preoperative status (OR = 38.9, 95% CI 5.4-278.7, P < .001) and high-dose trastuzumab (mg/kg, per 1 unit, OR = 60.6, 95% CI 20.1-182.9, P < .001) were independent risk factors for IRRs. CONCLUSION The results of this study suggest that premedication with dexamethasone exhibits preventive effects on trastuzumab-induced IRRs in breast cancer patients. Future studies are needed to determine the optimal dose of dexamethasone to prevent IRRs and the impact of dexamethasone on the efficacy of trastuzumab in breast cancer.

Abstract
PURPOSE The achievement of pathologic complete response (pCR) is strongly prognostic for event-free survival (EFS) and overall survival (OS) in patients with early breast cancer (EBC), and adapting postneoadjuvant therapy improves long-term outcomes for patients with HER2-positive disease not achieving pCR. We sought to investigate prognostic factors for EFS and OS among patients with and without pCR after neoadjuvant systemic treatment consisting of chemotherapy plus anti-HER2 therapy. MATERIALS AND METHODS We used individual data from 3,710 patients randomly assigned in 11 neoadjuvant trials for HER2-positive EBC with ≥100 patients enrolled, available data for pCR, EFS, and OS, and follow-up ≥3 years. We assessed baseline clinical tumor size (cT) and clinical nodal status (cN) as prognostic factors using stratified (by trial and treatment) Cox models separately for hormone receptor-positive versus hormone receptor-negative disease, and for patients who had pCR (pCR+; ypT0/is, ypN0) versus patients who did not achieve a pCR (pCR-). RESULTS The median follow-up overall was 61.2 months. In pCR+ patients, cT and cN were significant independent prognostic factors for EFS, whereas only cT was a significant predictor for OS. In pCR- patients, cT, cN, and hormone receptor status were significant independent predictors for both EFS and OS. Regardless of hormone receptor status, cT, and cN, the 5-year EFS/OS rates were higher in pCR+ patients than in pCR- patients. In most subsets with regards to hormone receptor and pCR status, cT and cN were independent prognostic factors for both EFS and OS, including pCR+ patients. CONCLUSION These results confirm that patients achieving pCR have far better survival outcomes than patients who do not. The traditional poor prognostic features, namely tumor size and nodal status, remain important even after a pCR.

Abstract
BACKGROUND The introduction of human epidermal growth factor receptor 2 (HER2)-targeted treatment options, including dual HER2 blockade, has improved the prognosis for patients with HER2-positive breast cancer (BC) substantially. However, most of these treatments are administered via the intravenous (IV) route, which can present many challenges, such as long infusion and observation times, issues associated with repeated IV access, and increased strain on time and resources of medical centers and healthcare professionals. A fixed-dose combination of pertuzumab and trastuzumab for subcutaneous (SC) injection (pertuzumab, trastuzumab, and hyaluronidase-zzxf (PHESGO®, F. Hoffmann-La Roche Ltd, Basel, Switzerland; PH FDC SC)) has been approved for use alongside chemotherapy for early-stage and metastatic HER2-positive BC. OBJECTIVES This systematic literature review was performed to identify evidence relating to time/resource use and resulting cost differences between SC and IV administration of oncology biologics in a hospital setting, and, ultimately, to inform economic modeling and associated health technology assessment of PH FDC SC. METHODS Electronic databases (Embase, MEDLINE, and EconLit) were searched on 9 April 2020. Additional hand searches were performed to identify publications not captured in the electronic database search. Publication screening and data extraction (study characteristics, participants, interventions, costs, and time/resource use) were carried out per the standard Cochrane review methodology. The quality of economic evidence of cost analyses was assessed using the 36-item checklist of the National Institute for Health and Care Excellence Single Technology Appraisal Specification for submission of evidence (January 2015). RESULTS The database search identified 2,740 records, of which 237 underwent full text screening. Full text screening, prioritization of publications about patients with a cancer diagnosis, and the addition of four citations identified during the hand search resulted in 72 final included publications, relating to 71 unique studies. This included 40 publications that described the time/resource use and/or costs associated with SC versus IV trastuzumab administration for the treatment of HER2-positive BC, and 28 publications that described time/resource use and/or costs associated with rituximab SC versus IV administration for the treatment of non-Hodgkin's lymphoma/follicular lymphoma and diffuse large B-cell lymphoma. The majority of publications showed substantial time savings for preparation and administration of SC versus IV therapy, and cost savings associated with reductions in healthcare professional time and resource use for SC administration. LIMITATIONS There was a lack of consensus between publications regarding time and cost measurements. In addition, the search was limited to publications related to anticancer drugs; the majority of the studies included were performed in European countries. CONCLUSIONS AND IMPLICATIONS This review indicated a substantial body of evidence showing time/resource and cost savings of SC versus IV administration of oncology biologics in a hospital setting, which can be used to inform economic evaluations of PH FDC SC.

Abstract
INTRODUCTION The glycosaminoglycan hyaluronan forms a gel-like substance, which presents a barrier to bulk fluid flow in the subcutaneous (SC) space, limiting SC drug delivery volume and administration rates. Recombinant human hyaluronidase PH20 (rHuPH20) acts locally to temporarily remove this barrier, facilitating rapid SC delivery of large volumes and/or high doses of sequentially or co-administered therapeutics. AREAS COVERED An extensive clinical and post-marketing dataset of safety and immunogenicity of rHuPH20 in its current applications with approved therapeutics demonstrates that rHuPH20 acts locally, without measurable systemic absorption at the SC doses used in the approved products, and is well tolerated in combination with several co-administered therapeutic agents across diverse patient groups. The immunogenicity profile demonstrates no adverse effects associated with treatment-emergent rHuPH20 antibody responses. Immunogenicity to monoclonal antibodies co-formulated with rHuPH20 shows no clinical difference between SC and intravenous administration. Safety assessments of patient subsets for special populations, including children, elderly patients, and pregnant women, raise no additional safety concerns. EXPERT OPINION The benefits of SC administration for patients and healthcare systems often outweigh those of intravenous administration, driving future initiation of SC-only drug development programs. Injection devices allowing large-volume SC administration could be facilitated by incorporating co-formulated biologics containing rHuPH20.

Abstract
Recent developments in genome editing and delivery systems have opened new possibilities for B cell gene therapy. CRISPR-Cas9 nucleases have been used to introduce transgenes into B cell genomes for subsequent secretion of exogenous therapeutic proteins from plasma cells and to program novel B cell Ag receptor specificities, allowing for the generation of desirable Ab responses that cannot normally be elicited in animal models. Genome modification of B cells or their progenitor, hematopoietic stem cells, could potentially substitute Ab or protein replacement therapies that require multiple injections over the long term. To date, B cell editing using CRISPR-Cas9 has been solely employed in preclinical studies, in which cells are edited ex vivo. In this review, we discuss current B cell engineering efforts and strategies for the eventual safe and economical adoption of modified B cells into the clinic, including in vivo viral delivery of editing reagents to B cells.

Abstract
Purpose To characterize pertuzumab pharmacokinetics (PK) in FeDeriCa (NCT03493854: fixed-dose combination of pertuzumab and trastuzumab for subcutaneous injection [PH FDC SC] versus intravenous pertuzumab plus trastuzumab); derive individual pertuzumab exposures in the PH FDC SC arm for subsequent pertuzumab exposure–response (ER) analyses; compare observed trastuzumab PK with predicted exposures from a previous SC trastuzumab model; assess whether pertuzumab affects trastuzumab PK; evaluate pertuzumab exposure–efficacy and –safety relationships and support the approved SC dosing regimen. Methods Population pharmacokinetic modeling and simulations were used to describe the data. Standard goodness-of-fit diagnostics and prediction-corrected visual predictive checks were used for model performance assessment. Covariates were included from previously reported models. ER analysis was conducted using logistic regression. Results SC pertuzumab PK was described adequately by a two-compartment model with first-order absorption; significant covariates included in the final model were albumin, lean body weight, and Asian region; however, these appeared not to be clinically relevant. Trastuzumab concentrations were described adequately by the previous model; there was no evidence of a pertuzumab effect on trastuzumab PK as part of PH FDC SC and higher model-predicted pertuzumab exposure was not associated with differences in pathologic complete response rate or an increased probability of selected grade ≥ 3 adverse events of interest. Conclusion The approved PH FDC SC dose [loading: 1200/600 mg pertuzumab/trastuzumab (15 mL); maintenance: 600 mg pertuzumab/trastuzumab (10 mL) and 2000 U/mL recombinant human hyaluronidase every 3 weeks] provides a positive benefit–risk profile with comparable efficacy and safety to intravenous pertuzumab plus trastuzumab.

Abstract
Trastuzumab, a key treatment for HER2-positive breast cancer, is available in weight-based IV and fixed-dose (600 mg) SC formulations. While the Phase 3 HannaH trial indicated non-inferiority of the SC formulation, there is some concern that the target plasma concentration may not be reached in overweight/obese patients whereas low-body-weight patients may be at risk of toxicity. This scoping review evaluated whether overweight/obese patients are at risk of below-target exposure with fixed-dose SC trastuzumab, whether low-body-weight patients are at risk of increased toxicity, especially cardiotoxicity, and whether IV and SC trastuzumab are equivalent in terms of treatment-emergent adverse events (TEAEs) (e.g. infections). Thirty-seven publications that met the eligibility criteria were included. Body weight is not an important determinant of exposure to trastuzumab at steady state (i.e. pre-dose cycle 8); however, real-world evidence suggests that the target concentration (20 μg/mL) may not be reached with the first SC dose in overweight/obese patients. There is no evidence that low-body-weight patients are at increased risk of cardiotoxicity with SC trastuzumab, although this may be confounded by the higher rate of cardiovascular comorbidities in overweight patients. In Phase 3 trials, SC trastuzumab was associated with higher rates of ISRs, ADAs and SAEs, the latter often requiring hospitalization and occurring during adjuvant treatment when patients are not burdened by chemotherapy. The route of administration of trastuzumab (IV vs SC) in different treatment settings should be discussed with the patient, taking into account the risks and benefits associated with each route.

Safety and tolerability of subcutaneous trastuzumab and intravenous pertuzumab as adjuvant treatment for HER2 positive breast cancer: a pilot study. Postgrad Med J 2021; 98:666-669. [PMID: 37062975 DOI: 10.1136/postgradmedj-2021-140319] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2021] [Accepted: 05/17/2021] [Indexed: 11/03/2022]
Abstract
BACKGROUND Subcutaneous (SC) trastuzumab is similar to intravenous trastuzumab in terms of pharmacokinetics, efficacy and tolerability. The use of dual anti-HER2 agents trastuzumab and pertuzumab has become the new standard for node-positive HER2-positive breast cancers at adjuvant setting, but the safety and tolerability of combining SC trastuzumab and intravenous pertuzumab is not well studied. METHODS This was a prospective single-arm pilot study with locally advanced HER2-positive breast cancer who received adjuvant SC trastuzumab and intravenous pertuzumab after standard anti-HER2 treatment with chemotherapy. Primary outcomes included adverse events (AEs), severe AEs and cardiac AEs. Secondary outcome was invasive disease-free survival (iDFS). RESULTS With a median follow-up of 21.7 months, 20 patients were enrolled. One patient (5%) developed asymptomatic drop in left ventricular ejection fraction from 69% to 53%. Two patients (10%) developed grade 1 injection site reaction related to SC trastuzumab. There were no grade 2 or above AEs. All AEs were transient. No new AEs were observed. The 1-year iDFS was 90% (95% CI 0.656 to 0.974) CONCLUSIONS: Combination of SC trastuzumab and intravenous pertuzumab for HER2-positive breast cancer is a safe and well-tolerated option in adjuvant setting.

Abstract
Purpose Intravenous trastuzumab, pertuzumab, and docetaxel are first-line standard of care for patients with HER2-positive metastatic breast cancer (mBC). MetaPHER is the first study assessing the safety and tolerability of subcutaneous trastuzumab plus intravenous pertuzumab and chemotherapy in a global patient population with HER2-positive mBC. Methods In this open-label, single-arm, multicenter, phase 3b study, eligible patients were ≥ 18 years old with histologically/cytologically confirmed previously untreated HER2-positive mBC. All received ≥ 1 subcutaneous trastuzumab 600 mg fixed dose plus intravenous pertuzumab (loading dose: 840 mg/kg; maintenance: 420 mg/kg) and docetaxel (≥ 6 cycles; initial dose 75 mg/m2) every 3 weeks. The primary objective was safety and tolerability; secondary objectives included efficacy. Results At clinical cutoff, 276 patients had completed the study; median duration of follow-up was 27 months. The most common any-grade adverse events were diarrhea, alopecia, and asthenia; the most common grade ≥ 3 events were neutropenia, febrile neutropenia, and hypertension. There were no cardiac deaths and mean left ventricular ejection fraction was stable over time. Median investigator-assessed progression-free survival was 18.7 months; objective response rate was 75.6%. Conclusions Safety and efficacy with subcutaneous trastuzumab plus intravenous pertuzumab and docetaxel in mBC are consistent with historical evidence of intravenous trastuzumab with this combination. Findings further support subcutaneous administration not affecting safety/efficacy profiles of trastuzumab in HER2-positive BC with increased flexibility in patient care. A fixed-dose combination of pertuzumab and trastuzumab for subcutaneous injection has recently been approved for the treatment of HER2-positive early/mBC, further addressing the increasing relevance of and need for patient-centric treatment strategies.

Clinical predictors of cardiac toxicity in HER2-positive early breast cancer patients treated with adjuvant s.c. versus i.v. trastuzumab. Breast 2021; 57:80-85.

Abstract
Background Few data are available about real-life cardiotoxicity associated with s.c. versus i.v. trastuzumab treatment of early-stage, HER2-positive breast cancer, and little is known about its predisposing factors. Patients and methods We retrospectively reviewed data of 363 adult patients treated with adjuvant trastuzumab for HER2-positive breast cancer. Univariate statistical analysis was performed, and a multivariable logistic model was developed to identify independent risk factors of cardiac toxicity. Results Within 5 years, the overall incidence of events meeting our criteria was 11.8%, and an early discontinuation of trastuzumab was recorded in 20 patients (5.5%). No cases of congestive heart failure occurred, neither multiple events per patient were observed. A total of 184 patients received i.v. and 179 received s.c. trastuzumab. Compared with the s.c. formulation, a higher cardiotoxicity rate for the i.v. administration (15.2% vs 8.4%) was found, and particularly in those patients with cardiovascular risk factors (19.3% vs 8.7%), at the univariate and multivariate analyses. Although more patients with prior anthracycline-based chemotherapy experienced cardiac events, the association of this therapy with cardiac events was not significant. The incidence of cardiac events was not influenced by anthropometric data (e.g. body mass index) or a diagnosis of diabetes mellitus. 5-year event-free survival was 91.7% in the overall population; event-free survival rates were similar between the s.c. and the i.v. groups. Conclusion Our study shows a more favorable safety profile of s.c. versus i.v trastuzumab administration. The use of s.c. trastuzumab could be advisable in at-risk patients. Few data are available about cardiotoxicity associated with s.c. versus i.v. trastuzumab and its predisposing factors. Our study shows a more favorable safety profile of s.c. versus i.v trastuzumab administration. Thus, the use of s.c. trastuzumab could be advisable in at risk patients.

Abstract
Therapeutic monoclonal antibodies and related products have steadily grown to become the dominant product class within the biopharmaceutical market. Production of antibodies requires special precautions to ensure safety and efficacy of the product. In particular, minimizing antibody product heterogeneity is crucial as drug substance variants may impair the activity, efficacy, safety, and pharmacokinetic properties of an antibody, consequently resulting in the failure of a product in pre-clinical and clinical development. This review will cover the manufacturing and formulation challenges and advances of therapeutic monoclonal antibodies, focusing on improved processes to minimize variants and ensure batch-to-batch consistency. Processes put in place by regulatory agencies, such as Quality-by-Design (QbD) and current Good Manufacturing Practices (cGMP), and how their implementation has aided drug development in pharmaceutical companies will be reviewed. Advances in formulation and considerations on the intended use of a therapeutic antibody, including the route of administration and patient compliance, will be discussed.

Abstract
BACKGROUND Despite the current recommendation for influenza vaccination in cancer patients with active oncological therapy, limited data are available on the efficacy of vaccination in cancer patients receiving targeted therapies. We aimed to investigate the immunogenicity and tolerability of influenza vaccination in breast cancer patients treated with trastuzumab in adjuvant setting. METHODS A prospective open-label multicenter study was performed including patients with breast cancer during trastuzumab treatment in adjuvant setting and healthy controls. Blood samples were taken before, 4 weeks after, and 12 weeks after a single dose of trivalent influenza vaccine containing inactivated A/California/7/2009 (H1N1) pdm09, A/Hongkong4801/2014 (H3N2), and B/Brisbane/60/2008. Levels of serum antibody titers to hemagglutinin for H1N1 and influenza B strains were measured. RESULTS Twenty breast cancer patients and 37 controls were included in the study. No difference in seroprotection rate between trastuzumab-treated patients and controls was observed for either H1N1 (100% in both groups) or B strain (78.9% vs. 89.2%, p value = 0.423). A statistically significant increase in geometric mean titers from baseline was seen in both groups and was evident both 4 weeks and 12 weeks after vaccination. Adverse events in the trastuzumab-treated group were uncommon and mild with only one serious adverse event not related to vaccination. CONCLUSION Breast cancer patients treated with trastuzumab in adjuvant setting seem to benefit from influenza vaccination in terms of immunogenicity without increasing the risk for adverse events. The current data support the recommendation to offer influenza vaccination in breast cancer patients treated with this type of targeted therapy.

Abstract
INTRODUCTION Trastuzumab is a monoclonal antibody which could induce the activation of a humoral immune response generating anti-drug antibodies (ADAs). Such response depends of the protein nature and the route of administration (intravenous or subcutaneous). The formation of these antibodies could block the action of trastuzumab (ADA-Tras) and forming immune complexes which decrease its efficacy, so it would be interesting to determine the presence of ADA-Tras in patients treated with trastuzumab. MATERIAL AND METHODS The blood samples were centrifuged to separate the plasma. The presence of ADA-Tras in plasma was determined using an ELISA-type automated immunoassay. RESULTS Fifty-one women with non-metastatic HER2-positive breast cancer treated with trastuzumab were included. Two groups were studied: patients treated intravenously and subcutaneously. In neither case was there any presence of ADA-Tras. DISCUSSION This study may be the first ever conducted under usual clinical practice conditions to detect the presence of ADA-Tras in patients with non-metastatic HER2-positive breast cancer. We have wanted to show the antibodies anti-trastuzumab determination as a possible tool that would enable comparison of potential differences in immunogenic behavior between trastuzumab and its biosimilars.

Hospital-based or home-based administration of oncology drugs? A micro-costing study comparing healthcare and societal costs of hospital-based and home-based subcutaneous administration of trastuzumab. Breast 2020; 52:71-77. [PMID: 32447129 PMCID: PMC7487951 DOI: 10.1016/j.breast.2020.05.001] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2019] [Revised: 04/26/2020] [Accepted: 05/01/2020] [Indexed: 12/24/2022] Open
Abstract
Objective To investigate resource use and time investments of healthcare professionals, patients and their family and to compare healthcare and societal costs of one single hospital-based and one single home-based subcutaneous administration of trastuzumab in The Netherlands. Method We conducted a bottom-up micro-costing study. Patients diagnosed with HER2+ early or metastatic breast cancer were recruited in four Dutch hospitals. For healthcare costs, data were collected on drug use, consumables, use of healthcare facilities, time of healthcare professionals, and travelling distance of the nurse. For societal costs, data were collected on patient and family costs (including travelling expenses and time of informal caregivers) and productivity losses of paid and unpaid work. Results Societal costs of one single administration of SC trastuzumab were €1753 within the home-based and €1724 within the hospital-based setting. Drug costs of trastuzumab were identical in both settings (€1651). Healthcare costs were higher for home-based administration (€91 versus €47) mainly because of more time of healthcare professionals (110 versus 38 minutes). Costs for patient and family were, however, lower for home-based administration due to travelling expenses (€7 versus €0) and time of informal caregivers (€14 versus €4). Costs for productivity losses were similar for both settings. Conclusions Home-based subcutaneous administration of trastuzumab is more time consuming for healthcare professionals and therefore more costly than hospital-based administration. The total budget impact can be large considering that a large number of patients receive a large number of cycles of oncology treatments. If home-based administration is the way forward, novel approaches are crucial for ensuring efficiency of home-based care. Home-based administration of SC trastuzumab almost triples the time of healthcare professionals. Healthcare costs are almost twice as much for home-based than for hospital-based administration. Patient and family costs are almost five times lower for home-based than for hospital-based administration.

Abstract
Background: This study estimated the economic and organisational impact of using subcutaneous injection (SC) formulations of two monoclonal antibodies (rituximab and trastuzumab) in patients with non-Hodgkin's lymphoma (NHL) and HER2 + breast cancer (BC).Methods: The database of the Unit of Oncology and Haematology of the IRST of Meldola was used. The analysis was structured as follows: i) measurement of the volume of Day-Hospital activity; ii) identification of activities and time to complete the administration; iii) estimate the mean cost of an SC or IV (intravenous infusion); iv) estimate the impact of SC formulations on the volumes of activities provided; v) estimate the social impact of SC or IV formulations.Results: The use of an SC formulation was associated a significant reduction in the time that the patient takes to complete the administration (trastuzumab -1 hr 18 min; rituximab -2 hr 24 min) and in consumption of healthcare resources and related costs for trastuzumab (IV: € 1781; SC: € 1701) and rituximab (IV: € 2116; SC: € 1941).Conclusion: The adoption of the SC formulation for rituximab and trastuzumab can generate a greater value for both the national healthcare system and the patient compared to an IV formulation.

Abstract
Purpose The subcutaneous (SC) administration of trastuzumab is highly preferred by patients. At home, administration of trastuzumab SC might further improve patient benefit. The aims of the BELIS study are to evaluate the safety and tolerability of trastuzumab SC when administered at home by a healthcare professional (HCP) and to evaluate patient-reported outcomes for treatment experience of at home cancer therapy. Methods This open-label phase IIIb study enrolled HER2-positive early breast cancer patients in Belgium and Israel who completed the first six cycles of trastuzumab IV (neo)adjuvant therapy. The study consisted of three consecutive treatment periods: three cycles of trastuzumab IV and SC each at the hospital and six cycles of trastuzumab SC at home. Results Between November 2013 and December 2014, 23 centres enrolled 102 patients in the intent-to-treat population of which 101 patients entered the safety population. No new safety signals were detected with as expected, more mild administration site events with trastuzumab SC when compared to IV treatment. All patients agreed that they had benefit from at home administration to a large (18/81; 22%) or very large (63/81; 78%) extent. All HCPs (21/21) agreed that SC is the quickest method from start of preparation to finish of administration and that less resource use is needed. Conclusion The results of the BELIS study support that trastuzumab SC can be safely administered at home by a HCP and all patients considered this setting as beneficial. HCPs consider the SC formulation as the quickest method to administer trastuzumab. Trial registration EudraCT Identifier: 2013-000123-13. ClinicalTrials.gov Identifier: NCT01926886.

Abstract
It has been more than three decades since the first monoclonal antibody was approved by the United States Food and Drug Administration (US FDA) in 1986, and during this time, antibody engineering has dramatically evolved. Current antibody drugs have increasingly fewer adverse effects due to their high specificity. As a result, therapeutic antibodies have become the predominant class of new drugs developed in recent years. Over the past five years, antibodies have become the best-selling drugs in the pharmaceutical market, and in 2018, eight of the top ten bestselling drugs worldwide were biologics. The global therapeutic monoclonal antibody market was valued at approximately US$115.2 billion in 2018 and is expected to generate revenue of $150 billion by the end of 2019 and $300 billion by 2025. Thus, the market for therapeutic antibody drugs has experienced explosive growth as new drugs have been approved for treating various human diseases, including many cancers, autoimmune, metabolic and infectious diseases. As of December 2019, 79 therapeutic mAbs have been approved by the US FDA, but there is still significant growth potential. This review summarizes the latest market trends and outlines the preeminent antibody engineering technologies used in the development of therapeutic antibody drugs, such as humanization of monoclonal antibodies, phage display, the human antibody mouse, single B cell antibody technology, and affinity maturation. Finally, future applications and perspectives are also discussed.

Van den Nest M, Glechner A, Gold M, Gartlehner G. The comparative efficacy and risk of harms of the intravenous and subcutaneous formulations of trastuzumab in patients with HER2-positive breast cancer: a rapid review. Syst Rev 2019; 8:321. [PMID: 31829250 PMCID: PMC6905114 DOI: 10.1186/s13643-019-1235-x] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/21/2019] [Accepted: 11/14/2019] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND Trastuzumab is a monoclonal antibody for patients with HER2 (human epidermal growth factor receptor 2)-positive breast cancer, which is added to regular treatment and reduces mortality. Originally, trastuzumab had to be administered intravenously (IV) over 30 min every 3 weeks for 1 year. Since 2012, a formulation for the subcutaneous (SC) administration of trastuzumab has been available, which has not yet been approved in the USA. Advocates claim that the SC formulation saves time and money, despite higher costs. The purpose of this study is to review existing literature concerning the comparative efficacy and risk of harms of trastuzumab IV and SC concerning patient-relevant health outcomes. METHODS We conducted searches in the Cochrane Library and MEDLINE for articles published through May 2018 in English or German. In addition, we searched ClinicalTrials.gov to identify unpublished studies. We dually reviewed the abstracts and full-text articles based on a priori defined inclusion criteria, rated the risk of bias of included studies, and assessed the strength of the evidence for each outcome of interest. Because data was insufficient for quantitative synthesis, we summarized results narratively. RESULTS We identified three RCTs (randomized controlled trials) meeting our eligibility criteria, which included data on 1003 patients. We found moderate evidence for similar event rates (20.05% vs. 18%, HR (hazard ratio) 0.88, CI 95% = 0.62-1.27), and mortality rates (10% vs. 8%, HR 0.76, CI 95% = 0.44-1.32) after 1.7 years for patients receiving trastuzumab IV and for patients receiving SC. Results remained similar after 3.3 years, though evidence lacked strength due to a high dropout rate. All trials reported more adverse events among the SC group than in the IV group. Evidence for these findings was of moderate strength. Nevertheless, more than 85% of the patients preferred trastuzumab SC over IV. Results concerning serious adverse events appeared to be heterogeneous. CONCLUSION Results of studies indicate similar efficacy between the two routes of administration. The higher rates of adverse events for SC administration were mainly attributable to injection site-related events. The clinical decision of whether to administer trastuzumab SC or IV requires the consideration of several factors and should be determined individually.

Safety profile of subcutaneous trastuzumab in patients with HER2-positive early breast cancer: The French HERmione non-interventional prospective study. Breast 2019; 49:1-7. [PMID: 31670262 PMCID: PMC7375678 DOI: 10.1016/j.breast.2019.10.002] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2019] [Revised: 10/13/2019] [Accepted: 10/14/2019] [Indexed: 11/20/2022] Open
Abstract
Objectives HERmione study was conducted to assess, in human epidermal growth factor receptor 2 (HER2)-positive early breast cancer (eBC), the safety profile of subcutaneous (SC) formulation of trastuzumab in real-life in France. Materials and methods This prospective, non-interventional study included 511 patients planned to be treated in both neoadjuvant and adjuvant settings with a follow-up of 12 months maximum in 101 sites. The safety analyses concerned 505 patients. Primary endpoint was the description of systemic safety and local tolerability of the SC trastuzumab. Results The median age of patients was 58 years. Over the study, 2449 adverse events (AEs) occurred in 422 (83.6%) patients (asthenia, arthralgia, radiation skin injury, myalgia, hot flush and diarrhea in ≥10% of patients): 92 AEs (3.8%) were grade ≥3 (radiation skin injury in 1.8% of patients and febrile neutropenia in 1.4% of patients), 76 (3.1%) were serious (mainly febrile neutropenia in 1.4% of patients) and 336 (13.7%) were treatment-related (mainly injection site pain in 9.1% of patients). Congestive Heart Failure occurred in 58 (11.5%) patients and was related to treatment in 4.6% of patients. Only 34 AEs (1.4%) in 27 (5.4%) patients led to permanent treatment discontinuation. One death was assessed as not treatment-related. Quality of life (QoL) analyses showed no deterioration of global health status. Conclusion The HERmione study showed that, in a real-life setting, the safety of SC trastuzumab administered in HER2-positive eBC patients is consistent with data reported from previous clinical trials, without new safety concerns or QoL deterioration.

Abstract
More oncology biologics are becoming available for subcutaneous (sc.) administration and are expected to provide useful therapeutic options. We evaluated evidence published in the past 5 years to assess the humanistic and economic impact of sc. versus intravenous administration of approved cancer therapies and identify outcomes favoring either administration route. These publications focused predominantly on healthcare resource utilization and economic outcomes, demonstrating resource and cost savings with sc. administration. Patients reported a better health-related quality of life and preference for sc. formulations. Time-and-motion study analyses confirmed the convenience of sc. administration. These findings suggest that future availability of sc. oncology biologics, especially anti-PD-1/PD-ligand 1 antibodies due to their increased utility in various malignancies, may be beneficial for patients, healthcare providers and payers.

Abstract
Trastuzumab is a monoclonal antibody used to treat human epidermal growth receptor 2 positive (HER2+) breast cancers either by itself or in combination with other chemotherapy medication. Marketing authorization was granted for a subcutaneous form of the antibody in 2014. In this case report, we discuss our experience with a patient who took part in a therapeutic education program on self-administration of trastuzumab. We demonstrate that these types of self-administered injections are not only possible but also are toxicity-free. Based on the tolerance data and our patient’s experience, we propose that the current regulations be relaxed regarding the availability of trastuzumab subcutaneous form in order to develop a cheaper “city scheme,” i.e. self-administered injections.

Abstract
There is little evidence on the costs associated with the route of administration of oncology drugs. We investigated time and resource use for hospitals and patients and compared healthcare and societal costs for intravenous (IV) and subcutaneous (SC) administration of trastuzumab and rituximab. Data for the preparation and administration of both drugs were collected at the hospital pharmacy and at the oncology day care unit. Patients completed a questionnaire for obtaining information on societal costs (productivity losses, informal care and traveling expenses). A total of 126 patients were recruited in six hospitals; 82 received trastuzumab (37 IV and 45 SC) and 44 received rituximab (23 IV and 21 SC). The costs per administration (including societal cost but excluding drug costs) were &OV0556;167 and &OV0556;264 for IV and &OV0556;76 and &OV0556;146 for SC trastuzumab and rituximab, respectively. The costs for SC administration were lower in all categories. The largest cost component was related to time spent at the day care unit (overhead costs). This resulted in savings of &OV0556;47 for SC trastuzumab and &OV0556;69 for SC rituximab. The costs related to time of healthcare professionals was &OV0556;9 lower for both drugs. The costs for consumables resulted in another &OV0556;12 savings. Societal costs were &OV0556;22 lower for SC trastuzumab and &OV0556;28 lower for SC rituximab. Although administration costs are relatively a small part of the total costs, important savings can be generated by switching to an SC route of administration especially because a large number of patients receive oncology drugs and patients receive more than one administration.

Abstract
Therapeutic antibody technology heavily dominates the biologics market and continues to present as a significant industrial interest in developing novel and improved antibody treatment strategies. Many noteworthy advancements in the last decades have propelled the success of antibody development; however, there are still opportunities for improvement. In considering such interest to develop antibody therapies, this review summarizes the array of challenges and considerations faced in the design, manufacture, and formulation of therapeutic antibodies, such as stability, bioavailability and immunological engagement. We discuss the advancement of technologies that address these challenges, highlighting key antibody engineered formats that have been adapted. Furthermore, we examine the implication of novel formulation technologies such as nanocarrier delivery systems for the potential to formulate for pulmonary delivery. Finally, we comprehensively discuss developments in computational approaches for the strategic design of antibodies with modulated functions.

Abstract
ENHANZE® drug delivery technology is based on the proprietary recombinant human hyaluronidase PH20 enzyme (rHuPH20; Halozyme Therapeutics, Inc.) that facilitates the subcutaneous (SC) delivery of co‐administered therapeutics. rHuPH20 works by degrading the glycosaminoglycan hyaluronan (HA), which plays a role in resistance to bulk fluid flow in the SC space, limiting large volume SC drug delivery, dispersion, and absorption. Co-administration of rHuPH20 with partner therapies can overcome administration time and volume barriers associated with existing SC therapeutic formulations, and has been shown to reduce the burden on patients and healthcare providers compared with intravenous formulations. rHuPH20 (as HYLENEX® recombinant) is currently FDA-approved for subcutaneous fluid administration for achieving hydration, to increase the dispersion and absorption of other injected drugs, and in subcutaneous urography for improving resorption of radiopaque agents. rHuPH20 is also co-formulated with two anticancer therapies, trastuzumab (i.e. Herceptin® SC) and rituximab (i.e. RITUXAN HYCELA®/RITUXAN® SC/MabThera® SC) and dosed sequentially with human immunoglobin to treat primary immunodeficiency (i.e. HyQvia®/HYQVIA®). This article reviews pharmaceutical properties of rHuPH20, its current applications with approved therapeutics, and the potential for future developments.

Abstract
Importance Confirmation of long-term comparability between subcutaneous and intravenous trastuzumab is essential. Objective To evaluate efficacy and safety of subcutaneous trastuzumab compared with that of intravenous trastuzumab for patients with ERBB2 (HER2)-positive early breast cancer after 6 years' follow-up in the HannaH (Enhanced Treatment With Neoadjuvant Herceptin) trial. Design, Setting, and Participants Open-label, prospective, multicenter, international, neoadjuvant-adjuvant, randomized, phase 3 noninferiority clinical trial (primary end points: pathologic complete response and serum trough concentration predose cycle 8) conducted for 596 patients with ERBB2-positive early breast cancer enrolled from October 19, 2009, to December 1, 2010. Interventions Eligible patients received 8 cycles of chemotherapy (4 cycles of docetaxel, 75 mg/m2, followed by 4 cycles of fluorouracil, 500 mg/m2, epirubicin, 75 mg/m2, and cyclophosphamide, 500 mg/m2) with either fixed-dose subcutaneous trastuzumab, 600 mg, or intravenous trastuzumab (loading dose, 8 mg/kg; maintenance dose, 6 mg/kg) every 3 weeks in the neoadjuvant setting. Patients received an additional 10 cycles of subcutaneous trastuzumab or intravenous trastuzumab (according to their initial randomization) after surgery in the adjuvant setting to complete 1 year of anti-ERBB2 therapy. Main Outcomes and Measures Event-free and overall survival rates were calculated using the Kaplan-Meier method. Hazard ratios were estimated by Cox proportional hazards regression. Adverse events and serious adverse events were graded per standard criteria. Results In total, 294 women (mean [SD] age, 50.3 [11.1] years) treated with subcutaneous trastuzumab and 297 women (mean [SD] age, 49.5 [10.8] years) treated with intravenous trastuzumab were included in respective intention-to-treat populations. Six-year event-free survival rates (65% in both study groups; hazard ratio, 0.98; 95% CI, 0.74-1.29) and overall survival rates (84% in both study groups; hazard ratio, 0.94; 95% CI, 0.61-1.45) were similar between the subcutaneous and intravenous trastuzumab groups. Patients achieving a total pathologic complete response had longer event-free survival and higher 6-year overall survival rates than those with residual disease. Incidence of adverse events (290 of 297 [97.6%] vs 282 of 298 [94.6%]), grade 3 or higher adverse events (158 of 297 [53.2%] vs 160 of 298 [53.7%]), cardiac events (44 of 297 [14.8%] vs 42 of 298 [14.1%]), and serious adverse events (65 of 297 [21.9%] vs 45 of 298 [15.1%]) was comparable between the subcutaneous and intravenous trastuzumab treatment groups. Conclusions and Relevance This final analysis of the HannaH trial further confirms the comparable efficacy and safety of subcutaneous and intravenous trastuzumab and highlights the suitability of subcutaneous trastuzumab as an alternative route of administration for patients with ERBB2-positive early breast cancer. Trial Registration ClinicalTrials.gov identifier: NCT00950300.

Abstract
Aim: Conjugated critical reagents are a pillar of ligand binding analysis. Although good practices for characterization have already been discussed, little is known about how assays are affected by specific conjugation parameters. Results: Here we developed, characterized and screened a toolset of bioconjugates that provided new insights about the optimization of conjugated critical reagent attributes. Biotinylated and sulfo-tagged trastuzumab were utilized as capture and detection antibodies, respectively, in an antidrug antibody (ADA) assay. The optimal conjugation window was identified by functional assessment. Excess of unlabeled biotin, but not sulfo-tag, affected the assay performance. An increase in the assay baseline was observed when sulfo-tagged trastuzumab underwent increasing freeze–thaw cycles. Conclusion: Upfront systematic screening and characterization of conjugated critical reagent attributes benefit assay robustness.

Abstract
Peptides and proteins bear an extraordinary therapeutic potential to effectively and selectively target many components of cells currently considered undruggable. However, their intracellular delivery remains a critical challenge. Cell penetrating peptides and protein domains (CPPs) can be employed to translocate therapeutic polypeptides through the cellular membrane. Here, we describe examples of linear peptides and proteins, byciclic macropeptides and nanobodies that target key players in cancer development, with intrinsic and engineered cell penetrating ability. We also describe current solutions to the main challenges to their clinical viability.

The increasing use of multiple immunomodulatory (IMD) agents for cancer therapies (e.g. antibodies targeting immune checkpoints, bispecific antibodies, and chimeric antigen receptor [CAR]-T cells), is raising questions on their potential immunogenicity and effects on treatment. In this review, we outline the mechanisms of action (MOA) of approved, antibody-based IMD agents, potentially related to their immunogenicity, and discuss the reported incidence of anti-drug antibodies (ADA) as well as their clinical relevance in patients with cancer. In addition, we discuss the impact of the administration route and potential strategies to reduce the incidence of ADA and manage treated patients. Analysis of published reports indicated that the risk of immunogenicity did not appear to correlate with the MOA of anti-programmed death 1 (PD-1)/PD-ligand 1 monoclonal antibodies nor to substantially affect treatment with most of these agents in the majority of patients evaluated to date. Treatment with B-cell depleting agents appears associated with a low risk of immunogenicity. No significant difference in ADA incidence was found between the intravenous and subcutaneous administration routes for a panel of non-oncology IMD antibodies. Additionally, while the data suggest a higher likelihood of immunogenicity for antibodies with T-cell or antigen-presenting cell (APC) targets versus B-cell targets, it is possible to have targets expressed on APCs or T cells and still have a low incidence of immunogenicity.

Economic benefits of subcutaneous trastuzumab administration: A single institutional study from Karolinska University Hospital in Sweden. PLoS One 2019; 14:e0211783.

Abstract
Introduction Adjuvant trastuzumab is a standard of care in the treatment of Human Epidermal growth factor Receptor 2 (HER2) positive early breast cancer (eBC). Initially trastuzumab could only be administered intravenously (IV), however since 2013, a subcutaneous (SC) formulation with comparable efficacy and safety profile is available and preferred by patients. Trastuzumab SC does not require pharmacy preparation and has shorter administration time. The objective of this study was to estimate the economic efficiency of the SC formulation of trastuzumab by assessing the economic benefits of actual SC-driven process changes at one single Swedish healthcare institution. Methods This study analyzes changes in trastuzumab administration practice after the SC formulation was introduced at the Karolinska University Hospital. Process changes were identified and introduced in order to capitalize on the inherent work efficiency benefits of the SC formulation. Actual hospital data for 2015 were used to quantitatively estimate the annual economic impact of the changes. It encompassed administrative (i.e. non-medical) data of 178 newly diagnosed HER2-positive eBC patients and a total of 2,769 SC administrations. Realized economic benefits were expressed in hours saved by nurses, direct monetary cost savings and potential infusion fee revenue that could be earned through infrastructural revenue gains. Results In 2015, the replacement of IV infusion to SC administration generated total time savings of more than 1,100 hours, and led to direct monetary cost savings of 603,000 EUR. It unlocked a capacity gain of 1–2 additional administrations daily within the existing facility infrastructure. Given the current remuneration structure per administration, this revenue gain translated into an incremental revenue potential of up to 3 million EUR. Conclusion Data from this study showed that the shift from trastuzumab IV to SC formulation resulted in significant economic effects in terms of departmental resources related to time, direct monetary cost savings, and infrastructural revenue gains.

Abstract
Adding pertuzumab to trastuzumab (both monoclonal antibodies targeting human epidermal growth factor receptor 2 [HER2]) has proven survival benefits when combined with chemotherapy for patients with HER2-positive breast cancer. The combination of pertuzumab and trastuzumab together in 1 vial for subcutaneous (SC) administration is being developed as a ready-to-use formulation to reduce the treatment burden on patients while improving healthcare efficiency. An open-label, 2-part, phase Ib dose-finding study (NCT02738970) was undertaken in healthy male volunteers (part 1) and female patients with HER2-postive early breast cancer who had completed standard (neo)adjuvant treatment (part 2). This study aimed to identify an SC pertuzumab dose given with recombinant human hyaluronidase that results in comparable exposure to that of the intravenous (IV) pertuzumab dose, based on pertuzumab serum trough concentration and area under the serum concentration-time curve. Pharmacokinetics (PK), safety, and tolerability of a single dose of SC pertuzumab given alone or in a fixed-dose combination (comixed or coformulated) with trastuzumab were also assessed. A maintenance dose of 600 mg for SC pertuzumab resulted in an equivalent exposure to that of IV pertuzumab, and no new safety signals were identified for SC pertuzumab or trastuzumab. A loading dose of 1200 mg for SC pertuzumab was selected based on approximate dose proportionality. The PK and safety results support further development of a fixed-dose coformulation combination of pertuzumab and trastuzumab for SC administration, which will be investigated in an upcoming phase III trial in patients with HER2-positive early breast cancer.

Abstract
BACKGROUND This SafeHer subgroup analysis assessed the safety of fixed-dose subcutaneous trastuzumab (H SC) as an adjuvant therapy in HER2-positive early breast cancer (EBC) by body weight. PATIENTS AND METHODS Patients with HER2-positive EBC not previously treated with anti-HER2 therapy received H SC 600 mg (every 3 weeks for 18 cycles), with neoadjuvant or adjuvant chemotherapy or without adjuvant chemotherapy. Adverse events (AEs) were assessed throughout treatment and at final follow-up (28 ±5 days after last treatment). Subgroups were categorized by body weight, Asian origin, and chemotherapy administration. All analyses were descriptive. RESULTS Of 2,577 patients enrolled, 2,573 received ≥1 dose of study medication and were included in this safety analysis. Median body weight at baseline was 67.0 kg (range 33.6-150.0 kg). Any-grade AEs occurred in 88.7% (2,282/2,573) of the overall population, versus 87.1% (590/677) of the lowest bodyweight quartile (≤59 kg), 90.0% (561/623) of the highest quartile (>77 kg), and 86.5% (327/378) of the Asian population. Grade ≥3 AEs occurred in 23.2% (596/2,573) of the overall population, 17.9% (121/677) of the lowest bodyweight quartile, 26.8% (167/623) of the highest quartile, and 15.3% (58/378) of the Asian population. The highest bodyweight quartile had the highest incidence of medical conditions at baseline (highest quartile, 75.6%; lowest quartile, 56.1%). CONCLUSION These data support the use of fixed-dose H SC as an adjuvant therapy in HER2-positive EBC and confirm the comparable safety profile of H SC in patients with low body weight or of Asian origin versus the overall population in SafeHer. ClinicalTrials.gov: NCT01566721. IMPLICATIONS FOR PRACTICE The safety profile of fixed-dose subcutaneous trastuzumab (H SC) was comparable between patients in the lowest bodyweight subgroup and the overall patient population, and also between patients of Asian origin (of whom a higher proportion often fall within the lower bodyweight quartiles) and the overall population. The safety data from this SafeHer subgroup analysis therefore support the use of fixed-dose H SC 600 mg administered every 3 weeks as an adjuvant therapy for patients with HER2-positive early breast cancer across different bodyweight subgroups and in the Asian patient population.

Abstract
Subcutaneous (SC) trastuzumab has long been approved as a cancer treatment for early and advanced HER2-positive (HER2+) breast cancer by both the European Medicines Agency (EMA) and Agência Nacional de Vigilância Sanitária (ANVISA), the Brazilian National Health Surveillance Agency. A pivotal non-inferiority phase III trial, which aimed to provide a more convenient and cost-effective treatment in the HER2+ breast cancer neoadjuvant setting, showed that the SC group met prespecified efficacy endpoints and the SC formulation was considered as safe as the intravenous (IV) formulation. Considering the recent approval of several biosimilars, new SC formulations are also an interesting manufacturer strategy as these drugs can obtain patent protection. Despite being considered non-inferior to the IV formulation of trastuzumab, in clinical development, the SC formulation elicited higher immunogenicity, mainly related to overall anti-drug antibodies (ADAs); however, this finding was classified as clinically non-significant. In this article, we explore different aspects of the benefits and risks of the SC trastuzumab formulation according to published data.

Abstract
Background We studies the expression of Coronin 1c and F-actin protein in breast cancer and explored their relationship with breast cancer metastasis. Material/Methods A total of 210 breast cancer tissues and adjacent normal tissues were collected from January 2013 to December 2014. The expressions of Coronin 1c and F-actin were detected by immunohistochemistry and Western blotting. We analyzed the relationship between Coronin 1c and F-actin and clinical data of breast cancer. Results The expressions of Coronin 1c and F-actin in breast cancer tissues were positively correlated (r=0.926, P<0.05) and were significantly higher than those in normal tissues (P<0.05). The Coronin 1c and F-actin expressions were not correlated with age, tumor size, ER expression, or PR expression in breast cancer patients (P>0.05), but were significantly correlated with HER-2 expression, histological grade, lymph node metastasis, molecular classification, and TNM (P<0.05). The expression of HER-2 in breast cancer tissues was positively correlated with the expression of Coronin 1c (r=0.706, P<0.05) and F-actin 1c, while F-actin protein in breast cancer tissues with lymph node metastasis was significantly higher than in those without lymph node metastasis (P<0.05). Conclusions Coronin 1c protein and F-actin protein are highly expressed in breast cancer and their expression may be related to the metastasis of breast cancer cells.

Abstract
BACKGROUND Monoclonal antibodies (mAbs) approved for use as add-on therapy in patients with severe asthma target the underlying pathogenesis of asthma. MAIN BODY Omalizumab binds immunoglobulin E (IgE), thereby inhibiting its interaction with the high-affinity IgE receptor and reducing the quantity of free IgE available to trigger the allergic cascade. Anti-interleukin (IL)-5 mAbs mepolizumab, benralizumab and reslizumab block the interaction between IL-5 and its receptor on eosinophils, thus targeting the eosinophilic pathway in asthma. Most mAbs are available as intravenous (IV) or subcutaneous (SC) formulations, as their high molecular weight and gastric degradation preclude oral administration. This review compares the pharmacology, efficacy, immunogenicity, injection- and infusion-related adverse drug reactions of subcutaneously administered omalizumab and mepolizumab with the intravenously administered reslizumab. In terms of pharmacokinetics, IV route of administration appears to be superior to the SC route due to quicker absorption, greater bioavailability, shorter time to maximum serum concentration and similar elimination half-life. Route of administration does not appear to translate into striking differences in efficacy and safety of mAbs used for the treatment of severe asthma, as all are generally considered to be effective and well tolerated. Hypersensitivity and administration-related reactions have been described with both IV and SC mAbs. CONCLUSION mABs are effective and have low immunogenicity due to their nature as humanised antibodies. Evidence on the use of mAbs in indications other than severe asthma suggest that both the SC and the IV routes of administrations have their respective advantages and disadvantages; but their full utility remains to be elucidated.

Abstract
The European patent for intravenous trastuzumab lapsed in 2017, and this stimulated research into a number of trastuzumab biosimilars. Quality assessment of their development and clinical results might enable establishment of a clinical hierarchy of these agents. This editorial will underline the key points for consideration when determining such an evaluation.

Abstract
The first biosimilar of bevacizumab was approved by the US FDA; other potential biosimilars of bevacizumab are in late-stage clinical development. Their availability offers opportunity for increased patient access across a number of oncologic indications. The regulatory pathway for biosimilar approval relies on the totality of evidence that includes a comprehensive analytical assessment, and a clinical comparability study in a relevant disease patient population. Extrapolation of indications for a biosimilar to other eligible indications held by the originator, in the absence of direct clinical comparison, frequently forms part of the regulatory judgment. Herein, we consider the evidence required to demonstrate biosimilarity for bevacizumab biosimilars, with particular focus on the rationale for extrapolation across oncologic indications.

Abstract
The anti-CD20 monoclonal antibody rituximab (MabThera®/Rituxan®) has been proven to improve outcomes in a range of B-cell malignancies. Initially developed as a formulation for intravenous infusion, administration times for rituximab can be prolonged and associated with infusion-related reactions, prompting a combined clinical development program investigating subcutaneous delivery in combination with recombinant human hyaluronidase. As this program comes to fruition, this article reviews the evidence demonstrating subcutaneous rituximab to have noninferior pharmacokinetics when delivered at a fixed-dose as well as equivalent clinical outcomes in the treatment of follicular lymphoma, chronic lymphocytic leukemia and diffuse large B-cell lymphoma. This mode of delivery is more preferable to patients and healthcare professionals and is associated with time and cost savings.
