Project description:IntroductionSatralizumab, an anti-interleukin-6 receptor antibody, is approved in Japan for relapse prevention in neuromyelitis optica spectrum disorder (NMOSD) and is undergoing post-marketing surveillance (PMS) of clinical use. We aimed to describe the real-world safety and effectiveness of satralizumab in Japanese patients with NMOSD.MethodsThis is an ongoing PMS (planned completion: February 2027). This 6-month interim analysis assessed the safety and effectiveness of satralizumab in Japanese patients with NMOSD using data collected from August 2020 to July 2021.ResultsAmong 570 patients who participated, 523 (91.75%) were female and the mean ± standard deviation (SD) age was 52.4 ± 14.1 years. At baseline, NMOSD expanded disability status scale mean ± SD was 4.19 ± 2.19; 490 (85.96%) patients used glucocorticoids and 277 (48.59%) patients used immunosuppressants concomitantly. Of 570 satralizumab-treated patients, 85 (14.91%) had discontinued satralizumab treatment at 6 months. For the overall adverse drug reactions (ADRs), 76.22 (66.07-87.48) events/100 person-years occurred in 118 (20.70%) patients, and infections occurred in 28 (4.91%) patients. Serious infections occurred in 18 (3.15%) patients, with an event rate of 9.05 (5.80-13.47) events/100 person-years. Of the 24 events of serious infections, respiratory tract infections (29.17%; 7) and urinary tract infections (25.00%; 6) were the most common serious infection events. One fatal ADR (septic shock) suspected to be related to satralizumab was reported. The mean ± SD glucocorticoid dose reduced from 12.28 ± 10.17 mg/day at the index date to 8.11 ± 7.30 mg/day at 6 months. The Kaplan-Meier cumulative relapse-free rate (95% confidence interval) was 94.59% (92.25-96.23) at 6 months.ConclusionIn this study, satralizumab was found to be safe, well tolerated, and effective in patients with NMOSD in routine clinical practice. The results are consistent with those of previous clinical trials. The safety and effectiveness of satralizumab in Japanese patients with NMOSD will be analyzed over the 6-year surveillance period.Trial registrationUMIN Clinical Trials Registry, UMIN000041047.

Project description:BackgroundROTASIIL, 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.MethodsObservational, 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.FindingsA 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.InterpretationROTASIIL was safe and well tolerated in this study. No safety concerns were reported.FundingThe study was funded by SIIPL which is the manufacturer of the study product.

Project description:Ibrutinib is approved in Japan for the treatment of chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) based on the results of global and domestic clinical studies. Following approval, we conducted an all-case post-marketing surveillance in Japanese patients with relapsed/refractory CLL/SLL newly initiated on ibrutinib treatment between May 2016-September 2017. Of the 323 patients enrolled, the safety and efficacy analysis sets comprised 289 and 205 patients, respectively. The overall response rate with ibrutinib treatment was 64.4%, and the estimated 52-week progression-free survival (PFS) and overall survival (OS) rates were 71.7 and 79.1%, respectively. No significant difference in the PFS rate was observed among patients with and without del(17p) (P = 0.160); however, PFS was significantly longer in patients who received 1 prior line of therapy versus >1 prior lines of therapy (P = 0.007). Adverse events occurred in 74.0% of patients, and typically occurred early (≤12 weeks) after ibrutinib initiation, followed by a decline in incidence thereafter. The overall rates of infection, bleeding, and arrhythmia were 22.5, 12.8, and 4.8%, respectively. Grade ≥3 bleeding events and atrial fibrillation occurred in 2.4% of patients each. The efficacy and safety profile of ibrutinib treatment in routine clinical practice was consistent with clinical trials and previously reported domestic data.UMIN-CTR Clinical Trials Register ID: UMIN000021963.

Project description:A diligent, systematic, regular review of aggregate safety data is essential, particularly early after vaccine introduction, as this is when safety signals not identified during clinical development may emerge. In October 2017, the US Centers for Disease Control and Prevention Advisory Committee on Immunization Practices recommended the adjuvanted recombinant zoster vaccine (RZV; Shingrix, GSK) as the preferred vaccine for preventing herpes zoster (HZ) and related complications in immunocompetent adults aged ≥ 50 years. Subsequently, GSK experienced an unprecedented high demand for RZV. In this methodology paper, we summarize the enhanced measures undertaken to assess RZV safety during its early post-marketing experience in the USA, Canada and Germany. In addition to the routine signal-detection methods already in place for all vaccines, GSK established tailored and enhanced safety monitoring for RZV based on aggregate data of spontaneous reports and manufacturing data. Proactive, near real-time detection and evaluation of signals was a key objective. A dedicated in-house signal-detection tool customized for RZV was employed on a weekly (rather than the routine monthly) basis, allowing for a centralized, more frequent review of data on a single web-based platform. We also identified the background incidence rates of preselected medical events of interest in the first countries to introduce RZV (USA, Canada and Germany) to perform observed-to-expected analyses. This approach may offer a solution to the challenges associated with the assessment and monitoring of vaccine safety in an efficient and timely manner in the context of high vaccine uptake.

Project description:BackgroundTofacitinib is an oral Janus kinase inhibitor for the treatment of ulcerative colitis (UC). Post-marketing surveillance (PMS) is an important part of monitoring adverse events (AEs).AimsTo report an analysis of PMS case safety reports for tofacitinib in patients with UC METHODS: Worldwide tofacitinib PMS reports received in the Pfizer safety database from 30 May 2018 (first regulatory approval) to 25 August 2020 were analysed. The type and estimated reporting rate (RR) of serious AEs of interest, including infection, gastrointestinal, vascular, respiratory, neoplasm and cardiac events, were reviewed. Patient-years of exposure (PY) was estimated based on worldwide sales data and the calculated daily regimens of tofacitinib 5 or 10 mg twice daily, immediate- or extended-release formulations.ResultsDuring the 27-month reporting period, worldwide post-marketing exposure to tofacitinib was 8916 PY. Overall, 4226 case reports were received and included 12 103 AEs, of which 1839 were serious AEs (SAEs). Among the cases reported, 1141 (27.0%) included an SAE and 18 (0.4%) were fatal. The RR (per 100 PY) for SAEs of interest by Medical Dictionary for Regulatory Activities System Organ Class were 3.28 for infections, 1.26 for vascular disorders, 0.74 for respiratory disorders, 0.55 for neoplasms and 0.50 for cardiac disorders.ConclusionsThe types of AEs were consistent with those reported in tofacitinib clinical trials. Most reported AEs were non-serious. Limitations of PMS reports and reliance on estimated RRs due to lack of precise values for exposure, required for incidence rate calculation, should be considered when interpreting these results.

Project description:BackgroundNivolumab has been approved for treating ≥ 10 cancer types. However, there is limited information on the incidence of rare, but potentially serious, treatment-related adverse events (TRAEs), as well as notable TRAEs in patients with certain medical disorders or older patients in Japan.MethodsWe performed pooled analyses of data from published post-marketing surveillance in Japan of nivolumab monotherapy for patients with malignant melanoma, non-small cell lung cancer, renal cell carcinoma, head and neck cancer, and gastric cancer to determine the frequencies of 20 categories of TRAEs of special interest overall and in patient groups with higher perceived safety risks (history of autoimmune disease, interstitial lung disease, tuberculosis, or hepatitis B/C; patients vaccinated during nivolumab treatment; and older patients [≥ 75 years]).ResultsThe overall population comprised 7421 patients treated with nivolumab. TRAEs were reported in 49.1% of patients, with grade ≥ 3 TRAEs in 16.7%. Endocrine disorders (14.4%), hepatobiliary disorders (10.9%), and interstitial lung disease (7.0%) were the three most common categories (any grade). The incidences of rare TRAEs with high risk of becoming serious, which occurred in < 1% of patients, were consistent with those in previous reports. The frequencies of TRAEs were not markedly increased in the specified patient groups relative to the overall population.ConclusionTo our knowledge, this is the largest study examining the safety of nivolumab-treated patients in real-world clinical practice including rare but potentially serious TRAEs. We found no new signals in the safety of nivolumab among the patient groups relative to the overall population, and no additional safety measures are required in these groups.

Project description:Objective: To evaluate the long-term safety and efficacy of glycopyrronium (GLY) in patients with COPD in a real-world setting in Japan. Methods: This 52-week, multicentre, post-marketing surveillance conducted in Japan, between February 2013 and August 2019, included patients using GLY for the first time for the relief of airway obstructive disorder-related symptoms. Safety outcomes included incidence of adverse events (AEs), serious AEs (SAEs), adverse drug reactions (ADRs), serious ADRs (SADRs) and priority variables included cardiovascular/cerebrovascular (CCV) AEs and anticholinergic AEs during the 52-week period. Safety outcomes were also assessed in elderly patients. Efficacy outcomes included physician’s global assessment, COPD assessment test (CAT) and lung function test. Results and Discussion: Of the 1,331 patients registered for this surveillance, safety and efficacy outcomes were evaluated in 1,277 patients. In the safety analysis population, the incidence of AEs was 15.51%, SAEs 4.70%, ADRs 5.01% and SADRs 0.31%. The CCV AEs and anticholinergic AEs were reported by 0.70% and 2.58% patients, respectively. Physician’s global assessment showed that the overall response rate at the last assessment was 70%. The mean (95% CI) CAT scores decreased from the start of treatment to Week 52 with GLY, (−6.2 [−7.0 to −5.4]). Lung function in terms of trough FEV1 and FVC improved over time from the start of GLY to Week 52. Conclusion: GLY demonstrated an acceptable long-term safety profile with no new safety concerns in a real-life setting. It demonstrated improvement in lung function and symptom control in Japanese COPD patients.

Project description:AimThe efficacy and safety of pirfenidone have been previously demonstrated in patients with mild-to-moderate idiopathic pulmonary fibrosis (IPF). However, the effect of pirfenidone in patients with advanced IPF remains unclear. Here, we investigated the effects of pirfenidone against advanced IPF in a real-world setting.MethodsA prospective nationwide post-marketing study was conducted on 258 patients from 10 Korean institutions. Patients with a predicted forced vital capacity (FVC) less than 50% or a diffusing capacity of the lung for carbon monoxide (DLco) less than 35% at baseline were classified as the advanced IPF group.ResultsOf 219 patients included in the analysis, the majority were male (76.3%); the mean age was 67.3 years, and the advanced group accounted for 17.8% of the patients. The median treatment duration was 298 days. Among the subjects, 86.3% experienced adverse events (AEs), of which a decreased appetite (32.4%) and a photosensitivity reaction (13.7%) were the most frequent. The incidence of AEs was similar between the advanced and non-advanced groups (92.3% vs. 85.0%, respectively; p = 0.229). Although the overall discontinuation rate was higher in the advanced group than in the non-advanced group (74.4% vs. 50.0%, respectively; p = 0.006), the percentages of the patients who discontinued treatment as a result of AEs were similar in both groups (20.5% vs. 23.3%, respectively; p = 0.704). In all patients, the rates of decline in the predicted FVC and DLco over 48 weeks were - 4.3 ± 1.3% and - 4.4 ± 1.7%, respectively. There was no between-group difference in the rate of lung function decline.ConclusionsPirfenidone used for the treatment of patients with IPF in a real-world setting was well tolerated, with an acceptable safety profile and a consistent therapeutic effect, regardless of the disease severity.Trial registrationClinicalTrials.gov NCT03761082; the trial was retrospectively registered on December 3, 2018.

Project description:BackgroundVortioxetine hydrobromide is a widely prescribed medication for the treatment of major depressive disorder (MDD), primarily exerting its antidepressant effects by inhibiting the reuptake of serotonin (5-HT).The objective of this study was to investigate adverse events (AEs) associated with vortioxetine hydrobromide through data mining in the FDA Adverse Event Reporting System (FAERS) to enhance clinical safety.MethodsWe collected FAERS data from Q3 2013 to Q1 2024 for data cleansing. Disproportionality analysis was employed to quantify relevant AEs associated with vortioxetine. Reported Ratio of Ratios (ROR) was utilized for identifying risk signals within the FAERS data. We employed the System Organ Classes (SOCs) and selected the Preferred Terms (PTs) from the Medical Dictionary for Regulatory Activities (MedDRA version 26.1).ResultsA total of 11,298 cases were reported as "primary suspected (PS)" for vortioxetine hydrobromide. Notably, at the systemic organ level (SOC) level, the adverse effects associated with vortioxetine hydrobromide involved 27 systemic organoid classes (SOCs).We identified 150 significantly disproportionate Preferred Terms (PTs) that met all four algorithms.ConclusionThis study identified adverse events (AEs) associated with vortioxetine. Our findings offer valuable insights for optimizing the use of vortioxetine hydrobromide and reducing potential side effects, serving as a reference for its rational and safe clinical application.

Project description:ObjectiveThis study was conducted to expand the sunitinib safety database in Japanese imatinib-resistant/-intolerant gastrointestinal stromal tumor patients. Retrospective analyses investigated common adverse events as potential prognostic markers.MethodsFour hundred and seventy patients who received sunitinib between June 2008 and November 2009 were analyzed for safety, progression-free survival and overall survival; 386 for objective response rate; 88% received sunitinib on Schedule 4/2 starting at 50 mg/day.ResultsNo unexpected safety issues occurred. Grade ≥ 3 adverse events occurred in 70%, most commonly thrombocytopenia (33%), neutropenia (22%) and leukopenia (15%). Objective response rate was 20% (95% confidence interval 16-24). Median progression-free survival was 22.4 weeks (95% confidence interval, 21.7-24.0). The overall survival rate at 24 weeks was 91% (95% confidence interval, 88-94). Higher relative dose intensity (≥70 vs. <70%) during the first 6 weeks and better Eastern Cooperative Oncology Group performance status (0 vs. ≥1) were associated with longer progression-free survival (24.0 vs. 20.1 weeks; P = 0.011; and 24.1 vs. 16.9 weeks; P < 0.001) and higher 24-week overall survival rate (94 vs. 83%; P < 0.001; and 96 vs. 83%; P < 0.001). Increased progression-free survival and overall survival rates were associated with specific adverse events. Cox proportional hazard modeling adjusted for relative dose intensity and performance status established hand-foot syndrome (hazard ratio = 0.636; 95% confidence interval, 0.456-0.888) and leukopenia (hazard ratio = 0.683; 95% confidence interval, 0.492-0.948) occurring within 12 weeks were significantly correlated with increased progression-free survival.ConclusionSunitinib showed good efficacy and tolerable safety. Factors associated with greater efficacy were relative dose intensity, performance status and specific early adverse events.
