Use of a Healthcare Claims Database for Post-Marketing Safety Assessments of Eribulin in Japan: A Comparative Assessment with a Prospective Post-Marketing Surveillance Study.

ABSTRACT: BACKGROUND:To understand the extent to which a large-scale healthcare claims database (DB) captures the safety profile of eribulin mesylate (Halaven®, Eisai Co., Ltd., Japan), we compared patient characteristics, drug use, and adverse events (AEs) between data for patients treated with eribulin retrieved from a DB and data for metastatic breast cancer patients from a conventional prospective post-marketing surveillance (PMS). METHODS:We descriptively summarized patient characteristics and AEs of 551 and 951 patients retrieved from DB and PMS, respectively, during 2011?2013. Using 2814 patient data from the DB during 2011?2016, the drug use and AE incidence over time were assessed. RESULTS:In both datasets, 99.8% were females, and the mean age was 57.8?±?10.7 years. The mean number of eribulin administration was 11.1?±?10.9 and 10.1?±?7.8 in DB and PMS, respectively. Although, overall, the difference in AE incidence between the two datasets was moderate, gaps were larger for nausea (DB: 73.32% vs. PMS: 15.77%), neutropenia (20.87% vs. 66.67%), stomatitis (37.39% vs. 10.94%), and alopecia (0.36% vs. 12.09%). During 2011?2016, the observed incidence of anemia or pyrexia significantly decreased (trend test, p?=?0.0009 for both). CONCLUSION:Generally, patient characteristics, drug use, and AE incidence between the DB and PMS were comparable; however, AEs such as neutropenia may require defining based on the laboratory data to achieve more comparable results in DBs. Besides the usefulness of healthcare claims DBs for long-term assessments, they may also serve as a good complementary to PMS in the pharmacovigilance of eribulin.

Project description:Highlights • Active post-marketing safety surveillance on ROTASIIL, an oral rotavirus vaccine, was conducted in 9940 infants in India.• Three doses of ROTASIIL were administered at 6, 10 and 14 weeks of age, along with other EPI vaccines.• Most of the AEs were pyrexia and injection site reactions caused by the concomitant injectable vaccines.• No case of intussusception (IS) was reported.• ROTASIIL was safe and well tolerated. Background ROTASIIL, an oral live attenuated bovine-human reassortant pentavalent rotavirus vaccine, was approved in 2017. This post-marketing surveillance (PMS) was conducted to collect real-world data on the safety of ROTASIIL in India. Methods Observational, active PMS was conducted in approximately 10,000 infants aged ≥ 6 weeks. ROTASIIL was administered as a 3-dose regimen, at least 4 weeks apart, beginning at ≥ 6 weeks of age concomitantly with other Expanded Programme on Immunization (EPI) vaccines. Participants were followed for one month after the last dose. The adverse events (AEs) and serious adverse events (SAEs), including intussusception (IS) reported during the follow up period were collected. Findings A total of 9940 infants were enrolled and were considered for safety analysis. Around 9913 (99.7 %) infants received 2 doses, while 9893 (99.5 %) infants completed all three doses. Total 3693 AEs were reported in 2516 (25.3 %) participants. Most of these AEs were pyrexia (78.01 % of events) and injection-site reactions (19.14 % of events). Nearly all AEs were causally unrelated to orally administered ROTASIIL and could be caused by the concomitant injectable vaccines. Only 4 AEs (2 events of vomiting and 1 event each of discomfort and pyrexia) in 4 (<0.1 %) participants could be related to ROTASIIL. AEs were of mild or moderate severity and all resolved without any sequelae. A total of 2 SAEs (acute otitis media and skull fracture) were reported in 2 (<0.1 %) participants and were not related to ROTASIIL and recovered without sequelae. No case of IS was reported. Interpretation ROTASIIL was safe and well tolerated in this study. No safety concerns were reported. Funding The study was funded by SIIPL which is the manufacturer of the study product.

Project description:IntroductionMolnupiravir is an orally available prodrug of N-hydroxycytidine that received special approval for emergency treatment of coronavirus disease 2019 (COVID-19) in Japan in December 2021 and full approval in April 2023. To assess the real-world safety and effectiveness of molnupiravir in Japanese patients with COVID-19, we conducted nationwide post-marketing surveillance to collect data at registered institutions in Japan.MethodsThe surveillance data were collected from December 27, 2021, to May 2, 2023. All reported adverse events were collected for safety analysis. Adverse drug reactions (ADRs) were assessed by the treating physicians. Effectiveness was assessed by the composite of hospitalization or all-cause death in outpatients and the composite of oxygen/mechanical ventilation initiation or all-cause death in inpatients. The observation period was from molnupiravir initiation through day 29.ResultsOf 3214 patients enrolled in the survey, 3179 were analyzed for safety. At baseline, 52.31% (1663/3179) of patients were male, the median (range) age was 69.0 (18-107) years, 82.38% (2619/3179) received COVID-19 vaccines, and 95.72% (3043/3179) had risk factors for severe COVID-19 illness. COVID-19 severity at baseline was mild in 86.44% (2748/3179) and moderate I in 10.22% (325/3179). A total of 205 ADRs occurred in 5.50% (175/3179) of patients; ADRs that occurred in > 0.5% of patients were diarrhea (1.86% [59/3179]) and rash (0.69% [22/3179]). Seven serious ADRs were reported in seven patients. In the effectiveness analysis population, the incidence of all-cause death through day 29 was 1.14% (34/2988), and the incidence of death through day 29 related to COVID-19 was 0.40% (12/2988). The cumulative incidence of the composite endpoint was 2.34% (47/2006) in outpatients and 4.60% (38/826) in inpatients.ConclusionsThis large-scale survey showed that molnupiravir was safe and effective in real-world settings in highly vaccinated Japanese patients with COVID-19, including older patients and those with comorbidities.

Project description:IntroductionDolutegravir (DTG), a novel HIV-integrase strand transfer inhibitor (INSTI), is usually used with multiple antiretrovirals (ARVs) for treatment of HIV. DTG is now approved as Tivicay tablets in over 120 countries and Triumeq combination tablets (DTG/abacavir [ABC]/lamivudine [3TC]) in over 90 countries. In Japan, these formulations have been marketed since 2014 and 2015. The post-marketing prospective surveillance has been conducted as part of the HIV-Related Drug (HRD) cooperative survey aimed to collect actual drug use information in all of these DTG-treated patients in accordance with conditions for initial approvals.MethodsThe survey has been conducted to evaluate long-term safety and effectiveness of DTG since 2014, for approximately 6 years. The safety was evaluated by incidence of adverse drug reactions (ADRs) and change in body weight. The effectiveness was evaluated by plasma HIV RNA copies/mL and peripheral CD4+ cell counts.ResultsOf 2292 patients in 30 Japanese sites, 565 (24.65%) reported ADRs. The most common ADR was blood creatinine increased (4.28%). Incidence of ADRs was statistically significantly higher in patients with severe symptoms (Centers for Disease Control and Prevention [CDC] categories B and C) than those with category A, and in patients with comorbidities than those without comorbidities. Whereas incidence of ADRs was statistically significantly lower in antiretroviral therapy (ART)-experienced patients than that in ART-naïve patients. Incidence of ADRs related to suicide or self-injurious behavior was statistically significantly higher in patients with comorbidities of psychiatric disorders than those without comorbidities. The body weight tended to increase over time and those changes and percentage changes from baseline were greater in ART-naïve patients compared with ART-experienced patients. HIV RNA copies/mL and CD4+ cell counts showed favorable shifts from baseline in both ART-naïve and ART-experienced patients.ConclusionThe results of the survey identified no new safety and effectiveness risks in Japanese patients with HIV/AIDS treated with DTG.
