Long-term tolerability and effectiveness of raltegravir in Japanese patients: Results from post-marketing surveillance.

ABSTRACT: Antiretroviral agents are approved in Japan based on non-clinical and clinical data reported from overseas. Neither the long-term tolerability nor the effectiveness of raltegravir or other integrase strand transfer inhibitors in Japan is known. This study reports on the long-term tolerability and effectiveness of raltegravir in Japanese clinical practice using data collected through approximately 9 years of post-marketing surveillance. This observational survey used data on human immunodeficiency virus (HIV) infected patients initiated treatment with raltegravir between 2008 and 2017 in the HIV-related drug (HRD) cooperative survey to assess the safety and effectiveness of raltegravir in real world clinical practice. There were totally 1,303 patients prescribed raltegravir across 30 institutions; 1,293 patients and 1,178 patients were included for the safety and effectiveness analyses, respectively. The overall risk of adverse drug reaction was 17.25%, with abnormal hepatic function and hyperlipidaemia (<1.5%) having the highest proportion. Median HIV-1 RNA viral loads rapidly decreased below 40 copies/mL after 3 months of raltegravir use in treatment-naïve patients, and consistently sustained below 40 copies/mL after the start of raltegravir use in treatment-experienced patients. Among the patients who were treated for 7 years, 92.00% (95% CI: 73.97-99.02) maintained HIV-1 RNA viral load below 50 copies/mL. Additionally, CD4+ cell counts exceeded >500 cells/?L in treatment-naïve and treatment-experienced patients after 3 years and 4 years of treatment, respectively. In Japanese HIV patients, long-term treatment with raltegravir is well-tolerated and effective at viral suppression as measured by HIV-1 RNA levels and subsequent change in CD4+ cell counts. Such benefits can be expected for not only treatment-naïve but also treatment-experienced patients.

Project description:INTRODUCTION:International clinical trials have shown that linagliptin significantly improves glycemic control and can be used at a single dose regardless of renal function in patients with type 2 diabetes (T2D). However, to date, no studies have evaluated the use of linagliptin in Japanese patients with T2D by renal function in routine clinical care. METHODS:This was a subgroup analysis of data from a prospective observational post-marketing surveillance (PMS) study of linagliptin conducted in Japan that evaluated the safety and effectiveness of linagliptin in routine clinical care for 3 years in Japanese patients with T2D. The subgroup analysis examined the patient population of this PMS study according to renal function using estimated glomerular filtration rate (eGFR) data. The incidence of linagliptin-related adverse events (adverse drug reactions [ADRs]) was the primary endpoint, and the change in glycated hemoglobin (HbA1c) from baseline to last observation was the secondary endpoint. RESULTS:Of the 2235 patients included in the safety analysis, eGFR was ≥ 90 mL/min/1.73 m2 (defined as group G1) in 16.9% (n = 377), ≥ 60 to < 90 mL/min/1.73 m2 (group G2) in 44.5% (n = 995), ≥ 30 to < 60 mL/min/1.73 m2 (group G3) in 21.7% (n = 486), ≥ 15 to < 30 mL/min/1.73 m2 (group G4) in 2.6% (n = 58) and < 15 mL/min/1.73 m2 (group G5) in 1.7% (n = 37). No eGFR data were available for 12.6% (n = 282) of patients. In these GFR groups, the incidence of ADRs with linagliptin was 6.9% in group G1, 11.1% in group G2, 13.8% in group G3, 15.5% in group G4 and 16.2% in group G5; the change in HbA1c from baseline to the last observation was - 1.11, - 0.64, - 0.35, - 0.46 and - 0.54% in the respective subgroups. CONCLUSIONS:Long-term linagliptin use showed sustained improvements in glycemic control with no new safety concerns regardless of renal function. TRIAL REGISTRATION:ClinicalTrials.gov (NCT01650259).

Project description:IntroductionThe present interim report of the STELLA-LONG TERM study aimed to examine the safety and effectiveness of ipragliflozin in real-word clinical practice in Japan using data up to 12 months. We also evaluated the effect of ipragliflozin on aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels in patients with normal vs. abnormal liver function.MethodsThis is an ongoing 3-year post-marketing surveillance study. We analyzed data from Japanese type 2 diabetes mellitus (T2DM) patients who were first prescribed ipragliflozin between 17 July 2014 and 16 October 2015 at participating centers in Japan, and whose data were locked by 16 January 2018. The incidence of adverse drug reactions (ADRs) was evaluated for safety. Changes in glycemic control and body weight were evaluated for effectiveness. The effect on liver function was evaluated by changes in the fatty liver index, and changes in AST and ALT were evaluated in patients with normal and abnormal liver function.ResultsThe safety analysis set comprised 11,051 patients and the efficacy analysis set comprised 8788 patients. The incidence rates of ADRs and serious ADRs were 14.6% (1616/11,051) and 0.97% (107/11,051), respectively. Significant reductions (all P < 0.001 vs. baseline, paired t test) in glycated hemoglobin (- 0.8%), fasting plasma glucose (- 31.9 mg/dL), body weight (- 2.9 kg), and fatty liver index (- 8.7) were observed. In patients with normal liver function at baseline, no clinically significant changes in AST and ALT were observed. In patients with abnormal liver function at baseline, clinically and statistically significant decreases (P < 0.05 vs. baseline, two-sample t test) in AST (- 9.0 U/L) and ALT (- 14.7 U/L) levels were observed.ConclusionIpragliflozin was effective and well tolerated in Japanese patients with T2DM over 12 months in the real-world clinical setting. Improvements in liver function parameters (AST and ALT) were observed in T2DM patients with abnormal liver function.Trial registrationClinicalTrials.gov identifier, NCT02479399.FundingAstellas Pharma Inc., Japan.

Project description:Background/aimA post-marketing surveillance (PMS) study is being conducted to investigate the safety and effectiveness of the long-term use of dabigatran etexilate (dabigatran) in Japanese patients with nonvalvular atrial fibrillation (NVAF). Results of an interim analysis of this prospective cohort study including patient characteristics and adverse drug reactions (ADRs) collected up to September 17, 2014 are reported here.MethodsPatients with NVAF who began to receive dabigatran for the first time from December 2011 to November 2013 were enrolled at 1042 study sites in Japan. Clinical parameters included patient characteristics, dabigatran dose strength, concomitant medications and outcome events. All outcome events were collected as serious and non-serious adverse events (AEs). ADRs were evaluated in this report. Pre-defined safety events of special interest for intensive survey were serious and non-serious outcome events such as myocardial infarction, as well as the total number of hemorrhage and gastrointestinal disorders.ResultsA total of 6772 patients were registered. The safety analysis set included 6148 patients; mean age was 70.8±9.9 (SD) years: 2323 patients (37.8%) were aged 75 years or older. Males accounted for 66.8% of the patients. Mean CHADS2 score was 1.8±1.3; the CHADS2 score was 0 in 13.6%, 1 in 31.3%, 2 in 25.9%, 3 in 14.9%, and 4 to 6 in 11.1% of the patients. Of the 6148 patients, 1701 patients (27.7%) were switchers from warfarin and 4407 patients (71.7%) were non-switchers (OAC naïve patients). Treatment adherence was assessed for the first 3 months from the start of treatment for this analysis. Total 5656 patients (92.0%) reported taking dabigatran twice daily (bid) every day according to the label recommendation. During the follow up period [mean duration of follow up: 498±259 days (corresponding to 8386 patient-years)], pre-defined safety events of special interest for intensive survey (reported as serious ADRs) were: myocardial infarction, reported in 5 patients (0.06 per 100 patient-years); serious hemorrhage, reported in 46 patients (0.55 per 100 patient-years); and gastrointestinal disorders (non-hemorrhagic), reported in 11 patients (0.13 per 100 patient-years). Fifteen patients had ADRs with fatal outcome.ConclusionsThe interim findings from this 6148 patient PMS study further corroborate the favorable safety profile of dabigatran as demonstrated previously in controlled clinical trials.
