Abstract
Purpose: Nusinersen is an antisense oligonucleotide for the treatment of spinal muscular atrophy (SMA). A post-marketing surveillance (PMS) has been ongoing (August 2017-August 2025) in all patients in Japan who received intrathecal nusinersen in real-world clinical settings. We report the interim analysis results of safety and effectiveness.Methods: This interim analysis was conducted using data collected from 401 patients whose case report forms were obtained at least once by 30 May 2020. Collected data included patient demographics and adverse events (AEs) for safety, and motor function assessments and Clinical Global Impressions of Improvement (CGI-I) for effectiveness.Results: All 401 patients were diagnosed with SMA and were included in the safety and effectiveness analysis (infantile-onset SMA [n = 126, 31.4%], later-onset SMA [n = 275, 68.6%]). The median duration of treatment was 330 days (range 1-823 days). The incidence proportion of AEs was 31.7% (37.3% in infantile-onset SMA and 29.1% in later-onset SMA). The most common AEs were headache (4.5%), pyrexia (4.2%), and pneumonia (3.7%). The incidence proportion of serious AEs was 11.5%. Nusinersen improved motor function scores and was assessed as 'effective' based on CGI-I in 99.7-100% of patients.Conclusions: This interim analysis of the PMS in Japanese patients treated with nusinersen found no new safety concerns, with the type of AEs consistent with the expected safety profile. The benefit-risk balance of nusinersen treatment remains favorable.

Abstract
The complexity and inter-connectedness of operating in a global world for drug product supply has become an undeniable reality, further underscored by the COVID-19 pandemic. For Post-Approval Changes (PACs) that are an inevitable part of a product's commercial life, the impact of the growing global regulatory complexity and related drug shortages has brought the Global PAC Management System to an inflection point in particular for companies that have their products marketed in many countries.This paper illustrates through data analyzed for the first time from 145,000 + PACs for 156 countries, collected by 18 global pharma companies over a 3-year period (2019-2021), how severe the problem of global regulatory complexity is. Only PACs requiring national regulatory agency (NRA) approval prior to implementation were included in the data set. 1 of the 156 country NRAs approved all submitted PACs within a period of 6 months. The 6-month timeline was chosen because it is the recommended review timeline for major changes in the WHO guidance for vaccines and biotherapeutic products. 10 out of the 156 (6%) countries had no more than 10% of the PACs reviewed and approved in > 6 months. In 33 (22%) countries more than half of the PACs took > 6 months for approval. It is rare that the same PAC is approved globally within 6 months as individual NRAs take from a few months to years (in some cases > 5 years) for their review.The global PAC management complexity has steadily grown over the past 20 years. Attempts thus far to solve this problem have not made any meaningful difference. Senior leaders and decision-makers across the interdependent components of the complex Global PAC Management System (industry and regulators) must come together and collaboratively manage the problem holistically with the objective of ensuring global drug product availability instead of continuing with distinct stakeholder or country-focused solutions, which can tend to worsen the problem.In this paper, the Chief Quality Officers (CQOs) from 18 of the largest innovator pharma companies (see Acknowledgements) are speaking with One-Voice-of-Quality for PACs (1VQ for PACs Initiative). They are recommending a set of 8 approaches to activate a holistic transformation of the Global PAC Management System. This article presents their view on the problem of global regulatory complexity for managing PACs, it's impact on continual improvement and the risk to drug product supply, as well as approaches that can help alleviate the problem.

Abstract
Pharmacovigilance (PV), also known as drug safety, is the science of risk management involving the detection, assessment, understanding, and prevention of adverse effects related to a medication. This discipline has traditionally focused on the postmarketing period, with less attention to early-phase clinical trials. However, during the immunotherapy and cellular therapy investigational stage, regulatory agencies are increasingly emphasizing the need to identify and characterize safety signals earlier in clinical development as part of a comprehensive safety surveillance plan. Compliance with PV and safety regulations are further heightened as cell and gene therapy (CGT) trials grow in complexity and scope owing to ever-changing and increasingly rigorous regulatory mandates. Based on this changing landscape, a critical aspect of early-phase trials of cellular products where significant safety events are anticipated is to ensure that every effort is made to protect clinical trial participants by maximizing attention to the risk-versus-benefit profile. This includes the development of robust plans for safety surveillance that provide a continual assessment of safety signals to enable safety reporting to regulatory bodies and the Food and Drug Administration, a regular analysis of aggregate safety data, and a plan to communicate safety findings. This report focuses on PV in early-phase clinical trials of first-in-human investigational products sponsored by academic centers in which the availability of PV resources and subject matter experts is limited. To more fully understand the challenges of CGT PV oversight within pediatric academic medical centers conducting early-phase clinical trials, a working group from institutions participating in the Consortium for Pediatric Cellular Immunotherapy composed of faculty and regulatory professionals was convened to compare experiences, identify best practices, and review published literature to identify commonalities and opportunities for alignment. Here we present guidelines on PV planning in early-phase CGT clinical trials occurring in academic medical centers and offer strategies to mitigate risk to trial participants. Standards to address regulatory requirements and governance for safety signal identification and risk assessment are discussed.

Abstract
INTRODUCTION Seasonal influenza is associated with substantial public health burden. The objective of this study was to assess the safety of inactivated quadrivalent seasonal influenza vaccine (IIV4, Fluarix Tetra, GSK, Belgium) in subjects aged ≥ 6 months in Korea. METHODS This prospective, observational, non-comparative, multi-centre post-marketing surveillance study was conducted in Korea in subjects aged ≥ 3 years for 6 years (2014-2020) and extended to subjects aged 6-35 months for 4 years (2018-2022). Subjects received IIV4 in routine clinical practice according to local prescribing information. Adverse events (AEs) were recorded over 21 days post-vaccination. RESULTS The group aged ≥ 3 years included 701 subjects (mean 31.97 years, range 3-86 years, 46.36% male), and the group aged 6-35 months included 687 subjects (mean 16.31 months, 47.02% male). In the group aged ≥ 3 years, 98 subjects (13.98%) reported 140 AEs, of which 42 events in 34 subjects (4.85%) were adverse reactions to vaccine (ARVs). Most of the ARVs were expected, mainly administration site reactions. There were seven mild unexpected ARVs. In the group aged 6-35 months, 248 AEs were reported in 149/687 subjects (21.69%). ARVs were reported in 25/687 subjects (3.64%, 29 events); one was considered unexpected. There were five serious AEs overall, none of which were considered related. CONCLUSION No safety concerns were found during this surveillance study of IIV4 in subjects aged ≥ 6 months in Korea. The findings of this study suggest IIV4 is safe and well tolerated for use in all age groups with a vaccine indication.

Abstract
Avelumab, a programmed cell death ligand 1 blocking antibody, was approved for its first indication in Japan in September 2017 to treat unresectable Merkel cell carcinoma (MCC). Given that the pivotal JAVELIN Merkel 200 study only included a few Japanese patients, this post-marketing surveillance (PMS) evaluated the safety and effectiveness outcomes of patients with MCC who received avelumab in general clinical practice in Japan. This prospective, non-comparative, multicenter PMS included data from all patients with unresectable MCC who received avelumab between November 22, 2017 (avelumab launch date) and October 31, 2019. The primary objective was to evaluate avelumab safety (i.e., adverse events [AEs], adverse drug reactions [ADRs], and ADRs of safety specifications). The secondary objective was to evaluate avelumab effectiveness (i.e., objective response rate and overall survival [OS] rate). Seventy-five evaluable patients were included, of whom 81.3% experienced AEs of any grade (57.3% experienced AEs of grade ≥ 3; 41.3% experienced AEs of grade 5) and 61.3% experienced ADRs (14.7% experienced ADRs of grade ≥ 3; no grade 5 ADRs were observed). The most common ADRs were pyrexia (18.7%), infusion related reaction (10.7%), and chills (6.7%). The most common ADRs of safety specifications were infusion reactions (any grade: n = 21 [28.0%]; grade 3 or 4: n = 3 [4.0%]), thyroid dysfunction (n = 7 [9.3%]), and hepatic function disorders (n = 4 [5.3%]). The median observation period was 51 weeks. An objective response was achieved by 34/75 patients (45.3%; complete response, 24.0%; partial response, 21.3%) and 6- and 12-month OS rates were 77.7% and 59.6%, respectively. This PMS confirmed the clinical tolerability and effectiveness of avelumab in patients with MCC, with no new safety concerns. The risk-benefit profile of avelumab was comparable with that observed in clinical trials and remains favorable for use in general clinical practice in Japan.

Abstract
OBJECTIVES An interim analysis of post-marketing surveillance data to assess the safety and effectiveness of sarilumab in Japanese patients with rheumatoid arthritis refractory to previous treatment. METHODS The interim analysis included patients who initiated sarilumab therapy between June 2018 and January 2021. The primary objective of this surveillance was safety. RESULTS In total, 1036 patients were enrolled and registered by 12 January 2021 (interim cut-off date). Of these, 678 were included in the safety analysis [75.4% female; mean age (± standard deviation) 65.8 ± 13.0 years]. Adverse drug reactions, defined as adverse events classified as possibly or probably related to sarilumab, were reported in 170 patients (incidence: 25.1%), with white blood cell count decreased (4.4%) and neutrophil count decreased (1.6%) most frequently reported. Serious haematologic disorders (3.4%) and serious infections (including tuberculosis) (2.5%) were the most frequently reported priority surveillance items. No malignant tumour was reported. An absolute neutrophil count (ANC) below the minimum standard value did not increase the incidence of serious infections. CONCLUSIONS Sarilumab was well tolerated, and no new safety signals were noted in this analysis. There was no difference in the frequency of serious infections between patients with an ANC below or above normal.

Abstract
BACKGROUND In January 2018, Afghanistan introduced the monovalent oral rotavirus vaccine (Rotarix) nationwide, administered as a 2-dose series at six and ten weeks of age. We describe characteristics of intussusception cases and assess potential intussusception risk associated with Rotarix vaccination in Afghan infants. METHODS Multi-center prospective active hospital-based surveillance for intussusception was conducted from May 2018 to March 2022 in four sentinel sites in Afghanistan. We applied the Brighton Level 1 criteria for intussusception and verified vaccination status by reviewing vaccine cards. We used the self-controlled case series (SCCS) methodology to compare intussusception incidence in the 1 to 21 days after each dose of Rotarix vaccination against non-risk periods. RESULTS A total of 468 intussusception cases were identified in infants under 12 months, with 264 cases aged between 28 and 245 days having confirmed vaccination status contributing to the SCCS analysis. Most case-patients (98 %) required surgery for treatment, and over half (59 %) of those who underwent surgery required intestinal resection. Nineteen (7 %) case-patients died. Eighty-six percent of case-patients received the first dose of Rotarix, and 69 % received the second dose before intussusception symptom onset. There was no increased risk of intussusception in the 1-7 days (relative incidence: 0.9, 95 % CI: 0.1, 7.5), 8-21 days (1.3, 95 % CI: 0.4, 4.2), or 1-21 days (1.1, 95 % CI: 0.4, 3.4) following receipt of the first dose or in the 1-7 days (0.2, 95 % CI: 0.3, 1.8), 8-21 days (0.7, 95 % CI: 0.3, 1.5), or 1-21 days (0.6, 95 % CI: 0.3, 1.2) following the second dose. CONCLUSION Rotarix vaccination was not associated with an increased intussusception risk, supporting its continued use in Afghanistan's immunization program. However, there was a high level of death and resection due to intussusception among Afghan infants.

Abstract
Patient profiles suitable for long-term lenvatinib treatment for unresectable hepatocellular carcinoma (uHCC) are yet to be fully understood. This post-hoc analysis aimed to identify such patient characteristics and explore the impact of treatment duration and relative dose intensity (RDI) on treatment outcomes. The data were obtained from 703 patients in a multicenter, prospective cohort study in Japan. Lenvatinib-naïve patients with uHCC were enrolled between July 2018 and January 2019 and were followed up for 12 months. Moreover, patients were dichotomized using the median treatment duration into the longer- (≥177 days; n = 352) or shorter-treatment (<177 days; n = 351) groups. The longer-treatment group often had better performance status, lower Child-Pugh score and better modified albumin-bilirubin grade than the shorter treatment group (p<0.05 for all). The objective response rate (47.6% vs. 28.2%; p<0.001) and disease control rate (92.4% vs. 60.2%; p<0.001) were both significantly higher in the longer-treatment groups than in the shorter-treatment groups. The proportion of patients with any adverse drug reactions was generally similar between the two treatment groups. Within the longer-treatment group, the disease control rate was high regardless of dose modification (i.e., RDI <100% vs. ≥100% during the initial 177 days) (91.2% vs. 98.0%). In conclusion, patients with longer treatment tended to have better overall conditions. Lenvatinib dose modifications at the physician's discretion, considering the balance between effectiveness and safety, may contribute to the long-term treatment.

Abstract
Purpose Omnitrope® (somatropin) was approved as a biosimilar recombinant human growth hormone (rhGH) in 2006. Here, we report final data from the PAtients TReated with Omnitrope® (PATRO) Children study, a post-marketing surveillance study designed to monitor the long-term safety and effectiveness of this treatment in pediatric patients. Methods The study population included all pediatric patients treated with Omnitrope® (biosimilar rhGH), administered via daily injection, in routine clinical practice. The primary objective was to assess long-term safety, with effectiveness assessed as a secondary objective. Results In total, 7359 patients were enrolled and treated in the PATRO Children study; 86.0% were treatment-naïve at baseline. Growth hormone deficiency was the most frequent indication (57.9%), followed by patients born small for gestational age (SGA; 26.6%). The mean (SD) duration of exposure to biosimilar rhGH was 3.66 years (2.39). A total of 16,628 adverse events (AEs) were reported in 3981 (54.1%) patients, most of which were mild/moderate. AEs suspected to be treatment related occurred in 8.3% of patients, most frequently headache (1.6%), injection-site pain (1.1%), or injection-site hematoma (1.1%). The incidence rate (IR) of type 2 diabetes mellitus was 0.11 per 1000 person-years (PY) across all patients, and 0.13 per 1000 PY in patients born SGA. The IR of newly diagnosed primary malignancies was 0.22 per 1000 PY across all patients. In the 6589 patients included in the effectiveness population, a sustained catch-up growth was observed across all indications. After 5 years of treatment, height SDS increased from baseline by a median (range) of +1.79 (-3.7 to 6.2) in treatment-naïve patients and +0.73 (-1.4 to 3.7) in pretreated patients. Conclusion This final analysis of the PATRO Children study indicates that biosimilar rhGH is well tolerated and effective in real-world clinical practice. These data are consistent with the well-characterized safety profile of rhGH treatment in pediatric patients.

Abstract
In the past decade, there have been a record number of oncology therapy approvals by the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA). Besides the EMA's conditional marketing authorisation programme and the FDA's Accelerated Approval Program, we observe a tendency towards fast approval for exploratory studies with non-randomised, uncontrolled designs and surrogate endpoints. This issue raises concerns about the robustness and effectiveness of accepted treatments, leaving patients and health-care professionals in a state of uncertainty. A substantial number of accelerated approvals have recently been withdrawn in the USA, with some still authorised in Europe, emphasising discrepancies in regulatory standards that affect both patients and society as a whole. We highlight examples of drugs, authorised on the basis of surrogate endpoints, that were later withdrawn due to an absence of overall survival benefit. Our findings address the challenges and consequences of accelerated approval pathways in oncology. In conclusion, this Policy Review calls for regulatory bodies to better align their procedures and insist on robust evidence, preferably through unbiased randomised controlled trials. Drug approval processes should prioritise patient benefit, overall survival, and quality of life to minimise risks and uncertainties for patients.

Abstract
Haematopoietic stem-cell transplantation (HSCT)-associated thrombotic microangiopathy (HSCT-TMA) is a serious complication with high mortality. Accumulating evidence suggests that complement dysregulation is potentially involved in the development of HSCT-TMA. We retrospectively analysed the clinical characteristics and outcomes of thirteen paediatric patients who were diagnosed with atypical haemolytic uremic syndrome and treated with eculizumab to manage HSCT-TMA during post-marketing surveillance in Japan. The median time from HSCT to TMA was 31 days (Interquartile range, IQR;21-58) and the median doses of eculizumab was three (IQR;2-5). Seven patients (54%) were alive at the last follow-up while six died due to complications related to HSCT. Six of seven survivors initiated eculizumab after insufficient response to plasma therapy. Following eculizumab treatment, median platelet counts and LDH levels in all survivors significantly improved and renal function improved in 4/7 patients. All survivors possessed potential risk factors of complement overactivation. During the follow-up period after eculizumab discontinuation (median;111.5 days, IQR;95-555), no TMA recurrence was observed. In this analysis, eculizumab showed benefit in over half of this paediatric patient population. Ongoing clinical studies are expected to optimize the treatment regimen of terminal complement pathway inhibitor, and it may become a therapeutic option for paediatric HSCT-TMA in the future.

Abstract
BACKGROUND To evaluate the occurrence of adverse drug reactions (ADRs) and to assess mortality and health status in participants receiving remdesivir in real-world settings in Japan. METHODS This postmarketing surveillance study used an all-case surveillance method for enrollment. Participants with SARS-CoV-2 infection administered remdesivir from July 2020 to November 2021 in Japan were eligible for inclusion. The observation period was from remdesivir treatment initiation to 4 weeks after the end of treatment or treatment discontinuation. Clinical status and outcomes were analyzed by Kaplan-Meier plots and compared across subgroups at baseline, Day 14, Day 28, and the final observation point. RESULTS The analysis included 2128 participants (mean age, 67 years; 71.4 % male; 84.1 % with current comorbidities). ADRs and serious adverse drug reactions (SADRs) were reported among 10.4 % and 1.2 % participants, respectively. Overall, 191/2127 participants died (mortality rate [95 % confidence interval], 11.10 [9.66-12.75] per 100 person-months), 1511/2127 showed clinical improvement (117.8 [112.0-123.9] per 100 person-months), 1392/2127 recovered (103.9 [98.6-110.0] per 100 person-months), and 216/324 were extubated (107.0 [93.6-122.3] per 100 person-months). CONCLUSIONS The incidence of ADRs and SADRs was low, and no new safety concerns were identified. Observed mortality and clinical improvement results were consistent with prior studies, confirming remdesivir's benefits in real-world settings in Japan.

Abstract
BACKGROUND Dose optimization is a focal point of many US Food and Drug Administration (FDA) drug approvals. We sought to understand the impact of the FDA's Postmarketing Commitments/Postmarketing Requirements (PMCs/PMRs) on dose optimization and prescriber labeling for oncology drugs. METHODS Publicly available information was aggregated for all FDA oncology drug approvals between January 1, 2010, and December 31, 2022. Study completion dates were compared to product labeling before and after PMC/PMR fulfillment dates to evaluate labeling changes associated with dose-related PMCs/PMRs. Data were analyzed individually (2010-2015 and 2016-2022) due to differences in available information. RESULTS From 2010 to 2015, 14 of 42 (33.3%) new molecular entities (NMEs) had dose-related PMCs/PMRs, with 6 of 14 (42.9%) resulting in a relevant label change. From 2016 to 2022, of the 314 new or supplemental applications approved, 21 had dose-related PMCs/PMRs (6.7%), which trended upward over time; 71.4% of dose-related PMCs/PMRs were NMEs. Kinase inhibitors (KIs) and antibody/peptide drug conjugates (ADCs/PDCs) were the most affected drug classes. Ten of the 21 approvals with dose-related PMCs/PMRs fulfilled their dosing PMCs/PMRs, and 3 of the 10 (30%) had relevant label changes. CONCLUSION Most dose-related PMRs/PMCs were issued for NMEs. Of these, KIs and ADCs/PDCs were highly represented, reflecting their novelty and greater uncertainty around their safety profile. PMC/PMR issuance broadly increased over time. With the implementation of the FDA's Project Optimus in 2021, it remains to be seen whether fewer dose-related PMCs/PMRs emerge in future due to enhanced dose optimization in the premarketing setting.

Abstract
Zinc is an essential microelement, and its deficit causes various diseases and symptoms. In adults, especially in elderly individuals, zinc shortage can cause symptoms such as taste disorder, dermatitis, and susceptibility to infection. In children, zinc deficiency can lead to growth retardation. In 2017, the indication for zinc acetate dihydrate (NOBELZIN®) was expanded from Wilson's disease to include hypozincemia, leading to wider use of zinc acetate dihydrate. At five years after this broadening of use, we conducted a post-marketing study (PMS) to investigate the utilization, safety, and effectiveness of zinc acetate dihydrate. Over 52 weeks, the overall incidence of adverse drug reactions (ADRs) was 9.4% (87/928). The most common ADR was copper deficiency (2.4%), followed by nausea (1.4%). Among 928 patients, 19 (2%) developed serious ADRs. Of the patients with copper deficiency, 92% were >65 years of age, and all had comorbidities at baseline. Physicians evaluated the effectiveness of zinc acetate dihydrate using three categories: "effective", "not effective", and "indeterminate". The overall efficacy rate was 83.0%. The average serum zinc levels were elevated from 50-60 μg/dL to >90 μg/dL within 12 weeks, and were maintained up to 52 weeks after administration. Among the symptomatic sub-categories, the efficacy rate was highest in pressure ulcer (96.2%; 25/26), followed by in stomatitis (87.5%; 42/48), and taste disorder (87.4%; 181/207). Among pediatric patients with developmental symptoms, an efficacy rate of 66% was achieved. In conclusion, zinc acetate dihydrate has been safely used, and has produced beneficial effects on various diseases and symptoms.

Abstract
OBJECTIVES We evaluated the real-world safety/effectiveness of tofacitinib, an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA), in patients with RA in Japan registered in a post-marketing surveillance study. METHODS This interim analysis included data from July 2013 to December 2018. Adverse events (AEs), serious AEs (SAEs), Simplified Disease Activity Index (SDAI)/Clinical Disease Activity Index (CDAI)/Disease Activity Score in 28 joints, erythrocyte sedimentation rate [DAS28-4(ESR)] scores, and rates of SDAI/CDAI/DAS28-4(ESR)-defined remission and low disease activity were analysed using 6 months of data. Risk factors for serious infections were assessed by multivariable analyses. RESULTS Safety and disease activity were evaluated in 6866 and 6649 patients, respectively. Overall, 32.73%/7.37% of patients reported AEs/SAEs. Clinically important AEs with tofacitinib included serious infections/infestations [3.13% of patients; incidence rate (IR; patients with events) 6.91/100 patient-years (PY)], herpes zoster (3.63%; IR 8.02/100 PY), and malignancies (0.68%; IR 1.45/100 PY). SDAI/CDAI/DAS28-4(ESR) scores and remission/low disease activity rates improved over 6 months. Male sex, older age, Steinbrocker's stage IV, history of infection, and diabetes mellitus at baseline were independent risk factors for serious infection. CONCLUSIONS In patients with RA receiving tofacitinib in Japan, safety was consistent with the reported profile, and disease activity improved over 6 months. STUDY IDENTIFIER NCT01932372.

Abstract
Efficacy and safety data for ibrutinib in Japanese patients with relapsed/refractory (R/R) mantle cell lymphoma (MCL) were limited at the time of its approval in Japan. All-case post-marketing surveillance was conducted in Japanese R/R MCL patients who began ibrutinib treatment between December 2016 and December 2017, and patients were followed until 30 June 2020. In the effectiveness analysis set (n = 202), the overall response rate was 59.9%, 52-week progression-free survival was 47.5%, and overall survival was 69.3%. Safety was assessed in 248 patients (median age 74.0 years). When ibrutinib treatment was started, patients had received a median of three prior lines of therapy. The overall incidence of adverse events (AE) was 74.6%, and AE frequency and severity grade distribution were similar between patients with 1 versus more than 1 prior line of therapy. The most common AE was platelet count decreased (all grades; 10.4%), similarly to previous observations in patients with R/R chronic lymphocytic leukemia/small lymphocytic lymphoma. Five patients (2.0%) developed atrial fibrillation. The effectiveness and safety of ibrutinib were consistent with its known profile at approval in Japan. These results suggest that ibrutinib is effective and safe in Japanese R/R MCL patients in routine clinical practice.

Abstract
With the premise of drug safety and effectiveness, pharmacoeconomic evaluation can provide optimal solutions for diversified decision-making application scenarios from different research perspectives while maximizing the rational utilization of existing healthcare resources. Chinese patent medicine is an essential component of pharmaceutical utilization in China and a significant part of healthcare expenditure in China. However, the economic evaluation of post-marketing Chinese patent medicine is lacking. These evaluations often lack standardization, exhibit varying quality, and are unable to effectively support healthcare decisions, indicating a need for improvement in overall quality. Given this situation, this project has gathered leading experts from China and has strictly adhered to the requirements of the group standards set by the China Association of Traditional Chinese Medicine in developing Guidelines for economic evaluation of post-marketing Chinese patent medicine, aiming to provide methodological guidance for the post-market pharmacoeconomic evaluation of Chinese patent medicine, enhancing the standardization of pharmacoeconomic evaluations of Chinese patent medicine and the scientific validity of research results, and thereby elevating the overall quality of pharmacoeconomic evaluations for post-marketing Chinese patent medicine. The guidelines adhere to the framework provided by relevant laws and regulations in China and technical guidance documents. It is based on guidance from traditional Chinese medicine(TCM) theories, focusing on the unique characteristics of TCM. It covers various aspects of pharmacoeconomic evaluation, including fundamental principles, research topic selection, research question definition, study design type selection, cost identification and measurement, health outcomes, and evaluation methods. The guidelines offer methodological recommendations and decision guidance to address common issues and challenges in the pharmacoeconomic evaluation of post-marketing Chinese patent medicine.

Abstract
Postmarket safety surveillance is an integral part of mass vaccination programs. Typically relying on sequential analysis of real-world health data as they accrue, safety surveillance is challenged by sequential multiple testing and by biases induced by residual confounding in observational data. The current standard approach based on the maximized sequential probability ratio test (MaxSPRT) fails to satisfactorily address these practical challenges and it remains a rigid framework that requires prespecification of the surveillance schedule. We develop an alternative Bayesian surveillance procedure that addresses both aforementioned challenges using a more flexible framework. To mitigate bias, we jointly analyze a large set of negative control outcomes that are adverse events with no known association with the vaccines in order to inform an empirical bias distribution, which we then incorporate into estimating the effect of vaccine exposure on the adverse event of interest through a Bayesian hierarchical model. To address multiple testing and improve on flexibility, at each analysis timepoint, we update a posterior probability in favor of the alternative hypothesis that vaccination induces higher risks of adverse events, and then use it for sequential detection of safety signals. Through an empirical evaluation using six US observational healthcare databases covering more than 360 million patients, we benchmark the proposed procedure against MaxSPRT on testing errors and estimation accuracy, under two epidemiological designs, the historical comparator and the self-controlled case series. We demonstrate that our procedure substantially reduces Type 1 error rates, maintains high statistical power and fast signal detection, and provides considerably more accurate estimation than MaxSPRT. Given the extensiveness of the empirical study which yields more than 7 million sets of results, we present all results in a public R ShinyApp. As an effort to promote open science, we provide full implementation of our method in the open-source R package EvidenceSynthesis.

Abstract
BACKGROUND Recently published studies have reported association of COVID-19 vaccine ChAdOx1-S (Vaxzevria) with Guillain Barré Syndrome (GBS). Less is known about the safety of other COVID-19 vaccines with respect to GBS outcome. This study investigated the association of COVID-19 vaccines with GBS in more than 15 million persons aged ≥12 years in Italy. METHODS Study population was all individuals aged ≥12 years who received at least one dose of COVID-19 vaccines, admitted to emergency care/hospital for GBS from 27 December 2020-30 September 2021 in Italy. Identification of GBS cases and receipt of at least one dose of mRNA-1273 (Elasomeran), BNT162b2 (Tozinameran), ChAdOx1-S (Vaxzevria) and Ad26.COV2.S (Janssen) through record linkage between regional health care and vaccination registries. Relative Incidence (RI) was estimated Self-controlled case series method adapted to event-dependent exposure using in the 42-day exposure risk period after each dose compared with other observation periods. RESULTS Increased risk of GBS was found after first (RI = 6.83; 95% CI 2.14-21.85) and second dose (RI = 7.41; 2.35-23.38) of mRNA-1273 and first dose of ChAdOx1-S (RI = 6.52; 2.88-14.77). Analysis by age found an increased risk among those aged≥60 years after first (RI = 8.03; 2.08-31.03) and second dose (RI = 7.71; 2.38-24.97) of mRNA-1273. The first dose of ChAdOx1-S was associated with GBS in those aged 40-59 (RI = 4.50; 1.37-14.79) and in those aged ≥ 60 years (RI = 6.84; 2.56-18.28). CONCLUSIONS mRNA-1273 and ChAdOx1-S vaccines were associated with an increased risk of GBS however this risk resulted in a small number of excess cases. Limitations were loss of GBS outpatient cases and imprecision of the estimates in the subgroup analysis due to a low number of events.

Abstract
OBJECTIVE Cabazitaxel has demonstrated improvements in overall survival among patients with metastatic castration-resistant prostate cancer (mCRPC) in the pivotal comparison clinical trials TROPIC, PROSELICA and CARD. However, these trials include mCRPC patients with similar characteristics, and there are limited data on how baseline characteristics affect treatment discontinuation in the patient population. METHODS To assess individual factors that may impact the discontinuation rate of cabazitaxel treatment, we conducted a post hoc analysis of data from a nationwide all-case, post-marketing surveillance of cabazitaxel in Japan. Patients were grouped according to the number of cabazitaxel treatment cycles received (1-2 and ≥3 cycles). Predictive factors were identified through multivariate logistic regression analysis. RESULTS Across 660 patients with metastatic castration-resistant prostate cancer, 70.2% received ≥3 cycles of cabazitaxel treatment. Those receiving 1-2 cycles of cabazitaxel had a greater proportion of patients with poorer Eastern Cooperative Oncology Group Performance Status, presence of lung and liver metastases, higher prostate-specific antigen level and prior radiation therapy at baseline. Regardless of the number of cabazitaxel cycles received, the primary reason for discontinuation was progression of disease rather than adverse events. Compared with those receiving 1-2 cycles, a lower proportion of patients receiving 3-10 and ≥11 cycles of cabazitaxel treatment experienced adverse events. Multivariate analysis showed a significant association between early discontinuation and presence of liver lesions, poorer Eastern Cooperative Oncology Group Performance Status and higher prostate-specific antigen level at baseline. CONCLUSIONS Post-marketing surveillance data suggest physicians should individualize cabazitaxel treatment based on certain patient characteristics at baseline.

Abstract
BACKGROUND Knowledge graphs are well-suited for modeling complex, unstructured, and multi-source data and facilitating their analysis. During the COVID-19 pandemic, adverse event data were integrated into a knowledge graph to support vaccine safety surveillance and nimbly respond to urgent health authority questions. Here, we provide details of this post-marketing safety system using public data sources. In addition to challenges with varied data representations, adverse event reporting on the COVID-19 vaccines generated an unprecedented volume of data; an order of magnitude larger than adverse events for all previous vaccines. The Patient Safety Knowledge Graph (PSKG) is a robust data store to accommodate the volume of adverse event data and harmonize primary surveillance data sources. METHODS We designed a semantic model to represent key safety concepts. We built an extract-transform-load (ETL) data pipeline to parse and import primary public data sources; align key elements such as vaccine names; integrated the Medical Dictionary for Regulatory Activities (MedDRA); and applied quality metrics. PSKG is deployed in a Neo4J graph database, and made available via a web interface and Application Programming Interfaces (APIs). RESULTS We import and align adverse event data and vaccine exposure data from 250 countries on a weekly basis, producing a graph with 4,340,980 nodes and 30,544,475 edges as of July 1, 2022. PSKG is used for ad-hoc analyses and periodic reporting for several widely available COVID-19 vaccines. Analysis code using the knowledge graph is 80% shorter than an equivalent implementation written entirely in Python, and runs over 200 times faster. CONCLUSIONS Organizing safety data into a concise model of nodes, properties, and edge relationships has greatly simplified analysis code by removing complex parsing and transformation algorithms from individual analyses and instead managing these centrally. The adoption of the knowledge graph transformed how the team answers key scientific and medical questions. Whereas previously an analysis would involve aggregating and transforming primary datasets from scratch to answer a specific question, the team can now iterate easily and respond as quickly as requests evolve (e.g., "Produce vaccine-X safety profile for adverse event-Y by country instead of age-range").

Abstract
OBJECTIVE Women and underrepresented minorities (URMs) who are at an increased risk of presenting with severe peripheral artery disease (PAD) and have different responses to treatment compared with non-Hispanic White males yet are underrepresented in PAD research. METHODS ELEGANCE is a global, prospective, multi-center, post-market registry of PAD patients treated with drug-eluting device that aims to enroll at least 40% women and 40% URMs. The study design incorporates strategies to increase enrollment of women and URMs. Inclusion criteria are age ≥18 years and treatment with any commercially available Boston Scientific Corporation drug-eluting device marketed for peripheral vasculature lesions; exclusion criterion is life expectancy <1 year. RESULTS Of 750 patients currently enrolled (951 lesions) across 39 sites, 324 (43.2%) are female and 350 (47.3%) are URMs (21.6% Black, 11.2% Asian, 8.5% Hispanic/Latino, and 5.3% other). Rutherford classification is distributed differently between sexes (P = .019). Treatment indication differs among race/ethnicity groups (P = .003). Chronic limb-threatening ischemia was higher for Black (38.3%) and Hispanic/Latino (28.1%) patients compared with non-Hispanic White (21.8%) and Asian patients (21.4%). De-novo stenosis was higher in Asian patients (92.3%) compared with Black, non-Hispanic White, and Hispanic/Latino patients (72.2%, 68.7%, and 77.8%, respectively; P < .001). Mean lesion length was longest for Black patients (162.7 mm), then non-Hispanic White (135.2 mm), Asian (134.8 mm), and Hispanic/Latino patients (128.1 mm; P = .008). CONCLUSIONS Analyses of data from the ELEGANCE registry show that differences exist in baseline disease characteristics by sex and race/ethnicity; these may be the result of other underlying factors, including time to diagnosis, burden of undermanaged comorbidities, and access to care.

Abstract
PURPOSE Under the Food and Drug Administration Amendments Act of 2007 (FDAAA), the FDA has the authority to require applicants to conduct postmarketing studies or clinical trials. These postmarketing requirements (PMRs) provide additional data on the safety of the drug product. The purpose of the study was to conduct a descriptive analysis of FDAAA PMRs and the resulting regulatory actions. METHODS This study evaluated FDAAA PMRs established between 2013 and 2019. We used the Medical Dictionary for Regulatory Activities (MedDRA) to map preferred terms (PTs) for serious risks associated with the PMRs. Relevant documents available in the FDA's document archiving, reporting, and regulatory tracking system (DARRTS), including but not limited to internal letters and reviews, documents submitted by applicants, and publicly available data sources were assessed for data collection of study elements. RESULTS Of the 1079 new FDAAA PMRs established between January 01, 2013, and December 31, 2019, 82% (n = 884) were associated with new drug applications (NDAs) and 18% (n = 195) with biologic license applications (BLAs). Most PMRs were established at the time of drug approval (73%, n = 789) compared to post-approval (27%, n = 290). The majority of PMRs had an open status (59%, n = 639) and 41% (n = 440) were closed. The median time from the PMR establishment date to submission of the results to the FDA was 690 days (interquartile range [IQR]: 748 days) for 167 completed clinical trials and 483 days (IQR: 603 days) for 241 completed studies. Approximately 53% (180/339) of fulfilled FDAAA PMRs resulted in labeling changes. CONCLUSIONS FDAAA PMRs are useful in informing postmarket safety of drugs. Most FDAAA PMRs were established at the time of drug approval, reflecting safety signals identified during the review of the marketing application, and over half of fulfilled FDAAA PMRs resulted in regulatory action.

Abstract
BACKGROUND Rasagiline is a monoamine oxidase B inhibitor for the treatment of Parkinson's disease (PD). This study assessed the safety and effectiveness of rasagiline in patients with PD in routine clinical practice in Japan. RESEARCH DESIGN AND METHODS This multicenter, prospective, observational study (148 sites) enrolled patients (1 November 2018-31 October 2020) with PD. Patients received rasagiline orally 1 mg once daily; maximum observation period was 24 months. The incidence of adverse drug reactions (ADRs) was evaluated; effectiveness was assessed using the Unified Parkinson's Disease Rating Scale (UPDRS) Part III total score. RESULTS The safety analysis set comprised 961 patients (mean age, 72.50 years; 53.80% female; mean duration of PD, 6.82 years). Mean treatment duration was 14.74 months, with 42.25% receiving rasagiline for ≥ 19 months; 189 (19.67%) had ≥ 1 ADR. Common ADRs were dyskinesia (4.06%), orthostatic hypotension (2.29%), hallucination (1.87%), visual hallucination, nausea, fall (1.56% each), dizziness (1.35%), and somnolence (1.25%). Mean (standard deviation) UPDRS Part III total score was 28.5 (14.35) at baseline and 25.5 (14.98) at the final assessment. CONCLUSIONS No new concerns in safety and effectiveness regarding rasagiline in Japanese patients with PD were raised.

Abstract
Human papillomavirus (HPV) infection is associated with the risk of developing certain cancers, including cancers of the cervix, vulva, vagina, penis, anus, rectum, and oropharynx. In 2016, the bivalent HPV-16/18 vaccine was included in the Korea National Immunization Program. This vaccine protects against HPV types 16 and 18 and other oncogenic HPV types predominant in cervical and anal cancers. This post-marketing surveillance (PMS) study assessed the safety of the HPV-16/18 vaccine in Korea. The study was conducted in males and females aged between 9 and 25 years, from 2017 to 2021. Safety was measured in terms of frequency and intensity of adverse events (AEs), adverse drug reactions (ADRs), and serious adverse events (SAEs) after each vaccine dose. The safety analysis included all participants who were vaccinated as per prescribing information and who completed a 30-day follow-up after at least one dose. Data were collected using individual case report forms. The total safety cohort included 662 participants. A total of 220 AEs were reported in 144 subjects (21.75%), and there were 158 ADRs in 111 subjects (16.77%), with the most common being injection site pain in all cases. No SAEs or serious ADRs were reported. Most AEs were reported after the first dose and were injection site reactions with mild intensity that recovered. No individuals required hospitalization or an emergency department visit. Safety results showed that the HPV-16/18 vaccine was generally well tolerated in the Korean population, and no safety concerns were identified.ClinicalTrials.gov Identifier: NCT03671369.

Abstract
The safety of human papillomavirus (HPV) vaccines, one of the major challenges to public vaccination, has been controversial. This study assessed the adverse reactions of 9-valent HPV (9vHPV) vaccines. This open-label, observational, multi-center, post-marketing study assessed the safety of 9vHPV administered according to local clinical practice. All post-marketing adverse events (AEs) reports received between December 2019 and November 2021 in Chongqing were analyzed. A total of 1000 individuals aged 16-26 years provided safety data post-vaccination; The most common AEs (60.1%) experienced by 9vHPV vaccine recipients were vaccination-site AEs (pain, swelling, induration) and non-vaccination-site AEs (dizzy, weak, fever). Vaccination-site AEs most were mild-to-moderate in intensity. Discontinuations and HPV 9-related serious AEs were rare (0.3% and 0.0%, respectively). Eight SAEs were reported during the study but none were considered as related to the study vaccine. The 9vHPV vaccine was generally well tolerated in subjects aged 16-26 years; Vaccination-site AEs were more common with 9vHPV.

Abstract
Following the approval of Cervarix for the immunization of girls and women in China against high-risk human papillomavirus types 16 and 18, a non-interventional post-authorization safety study was performed. A multi-center prospective cohort study assessed safety following Cervarix vaccination of Chinese girls and women aged 9-45 years between 31 May 2018 and 3 December 2020. Adverse events following immunization (AEFIs), potential immune-mediated diseases (pIMDs), and pregnancy-related outcomes were collected up to 12 months from the third immunization or 24 months from the first immunization, whichever came first. Among 3,013 women who received 8,839 Cervarix doses, 167 (5.5%) reported ≥ 1 any AEFI, and 22 (0.7%) reported 40 serious AEFIs. During the 30 days after each dose, 147 women (4.9%) reported 211 medically attended AEFIs, including 3 serious AEFIs reported by 1 woman (0.03%). One woman reported a pIMD. Cervarix was inadvertently administered to 65 women (2.2%) within 60 days before conception or during pregnancy. Of these women, 34 (52.3%) gave birth to live infant(s) with no apparent congenital anomalies, and 1 (1.5%) woman gave birth to a live infant with a congenital anomaly. No serious AEFIs or pIMDs were considered to be related to the vaccination. In Chinese women aged 9-45 years, immunization with the Cervarix three-dose schedule was well tolerated. Overall, no safety concerns were identified, although rare adverse events may have been missed due to the study sample size.Clinical trial registration: NCT03438006.

Abstract
PURPOSE This regulatory post-marketing surveillance (PMS) was organized to identify the safety and effectiveness of ambrisentan in the Korean population. METHOD This was an open-label, multi-center PMS conducted from 31 institutions in Korea for 6 years from August 2015 to 2021, to evaluate the use of ambrisentan for the treatment of pulmonary arterial hypertension (PAH). Inclusion criteria are Korean subjects with the World Health Organization functional classification (WHO Fc) II or III PAH who are new users or repeated users with ambrisentan (Volibris®) Tablet 5 or 10 mg per day (age >18 years old). RESULTS A total of 293 cases were analyzed. The overall incidence of adverse events (AE) was 52.22% and adverse drug reactions (ADR) was 10.92%. Severe AEs occurred in 20.82% of patients. However, only 2 subjects (0.68%) reported serious ADR. The difference in AE incidence was statistically significant for concomitant medications other than PAH medications in the safety analysis and the new users (p = 0.0041 and p = 0.0299, respectively) and elderly population in the repeated users (p = 0.0319). Among the long-term 223 subjects, the WHO Fc II and III were 41.26% and 58.74% before ambrisentan, and changed after treatment to 3.09%, 66.05%, and 30.86% for Fc I/II/III, respectively. 217 of 249 subjects (87.15%) considered their symptoms to have 'improved' after the last administration. CONCLUSION In real-world practice, ambrisentan demonstrated tolerable safety and favorable effectiveness in PAH patients in Korea. Age and concomitant drug use can affect the occurrence of AE.

Abstract
Information is needed to manage pregnancies with inadvertent exposure to baricitinib. A total of 117 pregnancies with exposure to baricitinib were identified among patients treated with baricitinib for rheumatoid arthritis, atopic dermatitis, or alopecia areata during clinical trials or in the postmarketing setting, and retrieved from the Eli Lilly global safety database. The clinical outcomes of the pregnancies with reported exposure to baricitinib appear to be comparable to those previously reported with other targeted therapies for immune-mediated diseases or in the general population.

Abstract
OBJECTIVES The aim of this article is to assess the safety and effectiveness of tofacitinib in patients with rheumatoid arthritis in routine clinical settings in Korea. METHODS This is a prospective, multi-centre post-marketing surveillance study. Data were prospectively collected within 6 months after the start of tofacitinib therapy. Safety was evaluated based on the presence of adverse events (AEs) observed in patients who received at least one dose of tofacitinib. Effectiveness was assessed according to the proportion of patients who achieved low disease activity and remission, American College of Rheumatology 20 criteria (ACR20), European League Against Rheumatism (EULAR) response, and change of Disease Activity Score in 28 Joints (DAS28). RESULTS The incidence rates [patients with events per 100 patient-years (PY)] of AEs and serious AEs were 56.92 and 10.69, respectively. Regarding AEs of special interest, the incidence rates were 4.33 per 100 PY for serious infections and infestations, 5.78 per 100 PY for herpes zoster, no event of tuberculosis, 0.29 per 100 PY for malignancy, 0.29 per 100 PY for venous thromboembolism (one event of deep vein thrombosis and no event of pulmonary embolism), 0.87 per 100 PY for major adverse cardiovascular event, and 0.58 per 100 PY for mortality. Moreover, ∼40.48% and 21.60% of patients achieved low disease activity and remission of DAS28-erythrocyte sedimentation rate. The EULAR response was classified as good responders with 39.12% in the DAS28-erythrocyte sedimentation rate. CONCLUSIONS The benefit/risk profile of tofacitinib in adult patients with rheumatoid arthritis in routine clinical settings in Korea was similar to long-term clinical trial data.

Abstract
Background: Data are limited for clinical outcomes with house dust mite (HDM) allergen immunotherapy beyond 2 years' observation. Materials & methods: A post-marketing drug-use survey assessed the safety and effectiveness of the 300 index of reactivity (IR) HDM tablet during use for up to 4 years in Japan. Results: 538 patients were evaluable for safety and 383 for effectiveness. Most adverse drug reactions (ADRs) occurred early and were local reactions; 5.6% of 249 total events were reported during years 2 to 4 as new ADRs after the interim analysis. The CAP-RAST score was identified as a potential risk factor for ADRs. The proportion of evaluable patients with severe allergic rhinitis symptoms decreased from 46.4% at baseline (n = 317) to 1.0% at 4 years (n = 104). Patients (n = 16) who discontinued 300 IR HDM tablet due to symptomatic improvement had sustained improvement relative to baseline 1 to 2 years later. Conclusion: Long-term use of the 300 IR HDM tablet is safe and effective.

Abstract
INTRODUCTION Turoctocog alfa pegol (N8-GP) is a glycoPEGylated, extended half-life (EHL), human recombinant factor VIII (FVIII) approved for the treatment and prevention of bleeding episodes in patients with haemophilia A. Since its launch in August 2019, > 800 patients have been treated worldwide. AIM To present data from identified post-marketing cases of less-than-expected FVIII activity in previously treated patients (PTPs) without inhibitors after switching to N8-GP. METHODS The post-marketing safety database was searched using keywords such as 'coagulation FVIII level decreased'. Identified cases reported prior to 13 October 2021 were included in this report. Cases in which patients had FVIII inhibitors were excluded. RESULTS Here we report 14 cases of less-than-expected FVIII activity. Details varied greatly amongst the cases. At presentation, FVIII activity ranged from 1% (15 min post-dose) to 51% (2 days post-dose). Seven patients experienced bleeding episodes after switching to N8-GP with heterogeneity in bleeding presentations. Six out of seven patients who were tested for anti-PEG IgG and/or IgM antibodies were positive. In all known cases, FVIII activity returned to the expected range when switched to an alternative FVIII replacement product. CONCLUSION In conclusion, the 14 reported cases of less-than-expected FVIII activity, without presence of detectable FVIII inhibitors, presented with heterogenous characteristics, and wide variations in FVIII activity and anti-PEG antibody titre. FVIII activity returned to the expected range after switching to alternative FVIII products. In line with WFH guidelines, monitoring of FVIII activity can ensure FVIII activity in the expected range. The safety surveillance of N8-GP continues.

Abstract
Lenalidomide was approved in Japan for the treatment of patients with myelodysplastic syndromes associated with a 5q deletion (del 5q-MDS) in August 2010. A post-marketing surveillance (PMS) study enrolled 173 patients with del 5q-MDS who started lenalidomide treatment between August 2010 and September 2011 (mean ± standard deviation [SD] age 72.4 ± 9.0 years) and observed for up to 6 cycles or 6 months. Adverse drug reactions (ADRs) and serious ADRs were reported in 78.0% and 50.9% of patients. The most commonly observed ADRs were thrombocytopenia or platelet count decreased (46.2%), neutropenia or neutrophil count decreased (42.2%), and rash (23.1%). Of 114 patients who were red blood cell transfusion-dependent at baseline, 39 (34.2%) achieved transfusion independence during lenalidomide treatment. Of 173 patients, 19 (11.0%) had confirmed acute myeloid leukemia (AML) progression during the study. Moreover, long-term follow-up (3 years) was available for 68 of the 173 patients, of whom 12 (17.6%) progressed to AML during the additional period. This PMS study investigated the safety and effectiveness of lenalidomide in patients with del 5q-MDS. No new safety concerns were noted in routine clinical use in Japan and no evidence was found for an increased risk of AML progression following lenalidomide treatment.

Abstract
Background: The infliximab biosimilar CT-P13 was approved in Thailand in 2015. Methods: This open-label, multicenter, post-marketing surveillance study evaluated the safety (events of special interest [ESIs]; primary end point) and effectiveness of 46 weeks of CT-P13 treatment according to routine practice in patients with rheumatoid arthritis (RA), ankylosing spondylitis (AS), or psoriatic arthritis (PsA), with 1 year follow-up post-treatment. Results: 30 patients were enrolled (16 RA, 8 AS and 6 PsA). Infections were the most frequently reported study drug-related ESIs (2 RA and 2 AS). One patient with RA and one with PsA experienced infusion-related reactions. No cases of tuberculosis, malignancy (as expected, given 1 year follow-up), or drug-induced liver disease were reported. Disease activity improved across indications. Conclusion: CT-P13 was well tolerated and effective across indications.

Abstract
Eculizumab is a C5 inhibitor approved for the treatment of paroxysmal nocturnal hemoglobinuria (PNH), atypical hemolytic uremic syndrome (aHUS), and anti-acetylcholine receptor antibody-positive generalized myasthenia gravis (AChR + gMG) in Japan. We report integrated safety data from post-marketing surveillance in these three indications, focusing on commonly occurring adverse events (AEs) and infection-related AEs. Of 1219 patients registered, 1055 (PNH: 780; aHUS: 192; AChR + gMG: 83) had available safety data. Total eculizumab exposure was 3977.361 patient-years. AEs were reported in 74.03% of patients. AEs with an incidence of ≥ 1.0 per 100 patient-years included hemolysis, headache, nasopharyngitis, renal impairment, anemia, pneumonia, upper respiratory tract inflammation, influenza, condition aggravated, and infection. The incidence of infection-related AEs was 21.30 per 100 patient-years, the most frequent types (≥ 1.0 per 100 patient-years) being nasopharyngitis, pneumonia, influenza, and infection. Meningococcal infections were reported in four patients (0.10 per 100 patient-years). Two patients died from meningococcal sepsis, with a mortality rate of 0.05 per 100 patient-years. This is the largest safety dataset on eculizumab in Japan derived from more than 10 years of clinical experience. No new safety signals were observed and the safety profile of eculizumab was consistent with that in previous clinical trials and international real-world safety analyses.

Abstract
We conducted a post-marketing surveillance of Zykadia® in patients with ALK-positive unresectable, advanced or recurrent non-small cell lung cancer. There were 573 patients included in the safety analysis, of which 54.62% were female, and their mean age was 59.9 years. Overall, 473 patients(82.55%)experienced side effects, which were mainly diarrhea in 43.46%, nausea in 34.38%, vomiting in 18.67%, and hepatic dysfunction in 16.40%. Side effects led to treatment discontinuation in 24.78%. Among 455 patients included in the efficacy analysis, the response rate was 30.99%. The median progression- free survival was approximately 4 months. The safety and efficacy were similar to those of previous reports, and this study confirmed that there are no problems requiring additional precautions in clinical use of Zykadia®.

Abstract
Congress mandated the creation of a postmarket Active Risk Identification and Analysis (ARIA) system containing data on 100 million individuals for monitoring risks associated with drug and biologic products using data from disparate sources to complement the US Food and Drug Administration's (FDA's) existing postmarket capabilities. We report on the first 6 years of ARIA utilization in the Sentinel System (2016-2021). The FDA has used the ARIA system to evaluate 133 safety concerns; 54 of these evaluations have closed with regulatory determinations, whereas the rest remain in progress. If the ARIA system and the FDA's Adverse Event Reporting System are deemed insufficient to address a safety concern, then the FDA may issue a postmarket requirement to a product's manufacturer. One hundred ninety-seven ARIA insufficiency determinations have been made. The most common situation for which ARIA was found to be insufficient is the evaluation of adverse pregnancy and fetal outcomes following in utero drug exposure, followed by neoplasms and death. ARIA was most likely to be sufficient for thromboembolic events, which have high positive predictive value in claims data alone and do not require supplemental clinical data. The lessons learned from this experience illustrate the continued challenges using administrative claims data, especially to define novel clinical outcomes. This analysis can help to identify where more granular clinical data are needed to fill gaps to improve the use of real-world data for drug safety analyses and provide insights into what is needed to efficiently generate high-quality real-world evidence for efficacy.

Abstract
Ravulizumab is a long-acting C5 inhibitor available for treating paroxysmal nocturnal hemoglobinuria (PNH). Post-marketing surveillance (PMS) was implemented following its approval in September 2019 in Japan. We report safety data obtained through to December 2021 for 218 patients and effectiveness data for 194 patients (182 switched from eculizumab and 12 complement inhibitor-naïve). Over a median follow-up of 74.4 weeks, 193 adverse events (AEs) were reported in 66/218 patients (30.3%; incidence 72.73/100 patient-years). The two most frequent AEs were anemia and pyrexia (each 3.01/100 patient-years). The incidence of serious AEs was 36.93/100 patient-years. In patients who switched from eculizumab, lactate dehydrogenase (LDH) and hemoglobin (Hb) levels were maintained over 26 weeks of ravulizumab treatment. In complement inhibitor-naïve patients, LDH decreased significantly and Hb increased significantly over 26 weeks of ravulizumab treatment. These data for Japanese patients with PNH who were naïve to complement inhibitors and patients who switched from eculizumab show that the safety and effectiveness of ravulizumab are consistent with the published clinical trial data. However, transfusion independence was less likely in patients with bone marrow failure. Further follow-up data from this PMS will help to elucidate the long-term clinical safety and effectiveness of ravulizumab for treating PNH.

Abstract
Although malignant melanoma is relatively rare in Japan, it is often diagnosed at a later stage than in Western countries. Nivolumab and ipilimumab are immune checkpoint inhibitors targeting programmed death 1 and cytotoxic T-lymphocyte-associated protein 4, respectively. Owing to their complementary anticancer effects, nivolumab and ipilimumab combination therapy (N + I) has been studied and approved for treating malignant melanoma in various countries including Japan. Real-world postmarketing surveillance was implemented to record treatment-related adverse events (TRAEs) in patients treated with N + I following its approval in Japan. Patients were eligible for registration if they had unresectable malignant melanoma and started N + I between September 2018 and August 2019. The observation period was 13 weeks from starting N + I. Only safety information was collected and evaluated. The final case report form lock was March 2021. Overall, 173 patients (median age, 66.0 years; performance status 0-1, 88.4%; skin: 53.2%; mucosal: 32.4%) were eligible for the analyses. Overall, 34.1% of patients completed 4 doses of N + I. N + I was discontinued by 63.0% (due to adverse events in 67.9% and disease progression/death in 22.9%). Any grade and grade ≥3 TRAEs were reported in 73.41% and 52.02%, respectively. TRAEs in ≥10 patients were hepatic function abnormal (any grade/grade ≥3: 23.12%/13.29%), pyrexia (10.40%/0.58%), diarrhea (9.25%/2.89%), rash (8.67%/0.58%), hypophysitis (5.78%/5.20%), interstitial lung disease (5.78%/2.89%), and liver disorder (5.78%/4.62%). TRAEs were classified as recovered (36.99% of patients), recovering (44.51%), unrecovered (13.29%), recovered with sequelae (2.31%), and death (1.73%). Overall, 24 of 34 patients (70.59%) with gastrointestinal-related and 53 of 65 (81.54%) liver-related TRAEs received treatment, such as a steroid with/without an immunosuppressant; most patients recovered within 1 to 2 months. In conclusion, this postmarketing surveillance of N + I in patients with unresectable malignant melanoma revealed no new safety concerns compared with results of prior studies. Immune-related TRAEs were generally manageable by appropriate treatment including a steroid.

Abstract
BACKGROUND The incidence of venous thromboembolism (VTE; pulmonary embolism [PE] and/or deep vein thrombosis [DVT]) in Japan is increasing, but relatively small numbers of patients from Japan have been included in studies investigating rivaroxaban (a direct factor Xa inhibitor) for the treatment of VTE and preventing its recurrence.Methods and Results: An open-label, prospective, observational study (XASSENT [NCT02558465]) investigated the safety profile and effectiveness of rivaroxaban for ≤2 years in the treatment of VTE and prevention of its recurrence in Japanese clinical practice. Primary outcomes were major bleeding and symptomatic recurrent VTE. Statistical analyses were exploratory and descriptive. Overall, 2,540 patients were enrolled (safety analysis population [SAP], n=2,387; effectiveness analysis population [EAP], n=2,386). In the SAP, >80% of patients received the approved rivaroxaban dose, the mean (standard deviation) age was 66.6 (15.0) years, ≈74% were >50 kg, and 43% had a creatinine clearance ≥80 mL/min. PE+DVT, PE only, and DVT only were reported in 42%, 8%, and 50% of patients, respectively, and active cancer in 17% of patients. Major bleeding was reported in 69 patients (2.89%; 3.60%/patient-year; SAP) and symptomatic PE/DVT recurrence in 26 patients (1.09%; 1.36%/patient-year; EAP) during the treatment period. CONCLUSIONS XASSENT provided information on the expected proportions of bleeding and VTE recurrence during rivaroxaban treatment in Japanese clinical practice; no new concerns of safety or effectiveness were found.

Abstract
OBJECTIVES Tacrolimus may be administered to pregnant women with lupus nephritis in Japan if considered therapeutically beneficial, but supporting data are limited. We assessed the safety and effectiveness of tacrolimus before, during, and after pregnancy in women with lupus nephritis receiving tacrolimus. METHODS This was an ad hoc analysis of data from a post-marketing surveillance study of tacrolimus in patients with lupus nephritis in Japan. Pregnancy outcomes, nephritis status, and adverse events were assessed for up to 2 years postpartum. RESULTS Data were available for 23 births in 21 patients (two patients had two births each). Tacrolimus for lupus nephritis was continued during 11 births in nine patients (during and after pregnancy) and discontinued in 12 patients (when pregnancy was known or when approaching delivery). Renal function was generally maintained in patients who gave birth while receiving tacrolimus; however, there were cases of increased urine protein and decreased renal function over 2 years. There were no unexpected adverse events/safety concerns. CONCLUSIONS These data from clinical practice suggest that tacrolimus is a valid treatment option for lupus nephritis in fertile women in Japan and, with careful monitoring, pregnant women with lupus nephritis may continue their tacrolimus treatment.

Abstract
The negative consequences of Substandard and falsified (SF) medicines are widely documented nowadays and there is still an urgent need to find them in more efficient ways. Several screening tools have been developed for this purpose recently. In this study, three screening tools were used on 292 samples of ciprofloxacin and metronidazole collected in Cameroon. Each sample was then analyzed by HPLC and disintegration tests. Seven additional samples from the nitro-imidazole (secnidazole, ornidazole, tinidazole) and the fluoroquinolone (levofloxacin, ofloxacin, norfloxacin, moxifloxacin) families were analyzed to mimic falsified medicines. Placebo samples that contained only inert excipients were also tested to mimic falsified samples without active pharmaceutical ingredient (API). The three screening tools implemented were: a simplified visual inspection checklist, a low-cost handheld near infrared (NIR) spectrophotometer and paper analytical devices (PADs). Overall, 61.1% of the samples that failed disintegration and assay tests also failed the visual inspection checklist test. For the handheld NIR, one-class classifier models were built to detect the presence of ciprofloxacin and metronidazole, respectively. The APIs were correctly identified in all the samples with sensitivities and specificities of 100%. However, the importance of a representative and up-to-date spectral database was underlined by comparing models built with different calibration set spanning different variability spaces. The PADs were used only on ciprofloxacin samples and detected the API in all samples in which the presence of ciprofloxacin was confirmed by HPLC. However, these PADs were not specific to ciprofloxacin since they reacted like ciprofloxacin to other fluoroquinolone compounds. The advantages and drawbacks of each screening tool were highlighted. They are promising means in the frame of early detection of SF medicines and they can increase the speed of decision about SF medicines in the context of pharmaceutical post-marketing surveillance.

Abstract
Importance Just-in-time interventions (JITIs) are a type of digital therapeutic intervention that combines remote monitoring tools and algorithms to personalize the delivery of specific interventions at the right time. The US Food and Drug Administration (FDA) regulatory approval documents are often the only available source of information on the effectiveness of therapeutic interventions based on these devices. Objective To systematically review the publicly available information from the FDA on all recently approved medical devices used in JITIs to (1) assess how they operate to deliver JITIs and (2) appraise the evidence supporting their performance and clinical effectiveness. Evidence Review Two reviewers systematically searched the Premarket Notifications (510(k)), Premarket Approvals, De Novo, and Humanitarian Device Exemption databases from January 2019 to December 2021 for all entries associated with devices that monitored patients' data over time to personalize the delivery of interventions to treat, prevent, or mitigate health conditions or events. They assessed whether the product summaries (1) enabled an understanding of how the device operated to deliver a JITI (eg, the nature, type, and frequency of the monitoring, the nature of the decision algorithm, and the nature and intended receiver of the intervention); (2) informed about the performance and effectiveness of the JITI; and (3) included information on data security and ownership. Findings In total, 38 devices were included in this review. These were mainly intended for cardiac conditions (12 [31.6%]), diabetes (10 [26.3%]), and neurological diseases (4 [10.5%]). Monitoring devices ranged from wearable (18 of 28 [64.4%]; eg, smartwatches) to implanted sensors (6 of 28 [21.4%]; eg, inserted electrocardiographic sensors). Only 10 of 38 product summaries (26.3%) allowed a full understanding of how the device operated to deliver a JITI. Similarly, only 12 of 28 (42.9%), 12 of 36 (33.3%), and 5 of 38 (13.2%) reported the assessment of the performance of the monitoring device, assessment of the decision algorithm, and results of clinical studies assessing the effectiveness of the JITI, respectively. Finally, 14 of 36 product summaries (38.9%) included some information on data security, but none included information on data ownership. Conclusion and Relevance The results of this systematic review suggest that the information publicly available in the FDA databases on the performance and effectiveness of digital medical devices used in JITIs is heterogeneous.

Abstract
BACKGROUND Sodium-glucose co-transporter-2 (SGLT2) inhibitors such as empagliflozin are increasingly prescribed as initial glucose-lowering drugs for type 2 diabetes (T2D), based on their cardiorenal benefits. However, information regarding the safety and the effectiveness of monotherapy with SGLT2 inhibitors in routine clinical practice is limited. RESEARCH DESIGN AND METHODS We analyzed data from a prospective, 3-year, post-marketing surveillance study of empagliflozin in Japan. We evaluated adverse drug reactions (ADRs) (the primary endpoint) and glycemic effectiveness with or without other glucose-lowering drugs. RESULTS 7931 T2D patients were treated with empagliflozin. At baseline, mean age was 58.7 years, 63.0% were male, and 1835 (23.14%) were not receiving other glucose-lowering drugs. ADRs occurred in 141 (7.68%) and 875 (14.62%) patients initiating empagliflozin as monotherapy or combination therapy, respectively. The most frequent ADRs of special interest with empagliflozin as monotherapy or combination therapy were urinary tract infections (0.82% and 1.14% of patients, respectively) and excessive/frequent urination (0.65%, 1.50%). At last observation, glycated hemoglobin level was reduced by a mean of 0.78% with empagliflozin monotherapy (from baseline mean of 7.55%) and 0.74% with combination therapy (baseline 8.16%). CONCLUSIONS Empagliflozin is well tolerated and effective in clinical practice in Japan when initiated as monotherapy or combination therapy.
