INTRODUCTION:Obesity is highly prevalent in India, creating an urgent need for effective management interventions. The study hypothesizes that synthetic semaglutide has comparable safety and efficacy to the innovator drug when used in obese adults for weight management. METHODS:A phase III multicenter randomized active-controlled non-inferiority trial enrolled adults with obesity across 19 centers in India. Subjects were randomized to the test arm receiving synthetic semaglutide (Alkem Laboratories Limited) or the reference arm administered with innovator semaglutide (Wegovy®, Novo Nordisk) over 24 weeks in a 2:1 ratio. The primary efficacy endpoint was the percentage change in body weight,24 weeks post-intervention. Synthetic semaglutide was established to be non-inferior if the lower bound of the one-sided 97.5% confidence interval for the between-group difference did not exceed 4.5%. RESULTS:Of the 249 randomized participants, 246 (98.8%) completed the study. Mean percentage weight loss after 24 weeks was -14.39 ± 4.17% in the test arm and -14.61 ± 4.36% in the reference arm. The least square-mean difference was 0.15% (-0.93 to 1.24), meeting the predefined non-inferiority criterion. Weight loss >10% was achieved by 86.67% (n=143) in the test arm and 83.95% (n=68) in the reference arm (p = 0.5666), while >15% weight loss occurred in 38.79% (n=64) and 40.74% (n=33), respectively (p = 0.7683). Mean body mass index decreased by -4.93 ± 1.43 kg/m² in the test arm and -5.00 ± 1.50 kg/m² in the reference arm (p = 0.7128). Treatment-emergent adverse events were reported in 55.42% (n=92) of test-arm participants and 54.22% (n=45) of reference-arm participants. CONCLUSIONS:Test semaglutide demonstrated non-inferior efficacy, comparable safety, and similar tolerability to the innovator product.
PURPOSE:The aim of this study was to evaluate the safety and feasibility of ipatasertib combined with trastuzumab and pertuzumab (HP) as maintenance therapy after first-line treatment in patients with HER2-positive metastatic breast cancer harboring PIK3CA mutations (PIK3CAmut). PATIENTS AND METHODS:This prospective, multicenter, single-arm, phase Ib study evaluated the safety and preliminary efficacy of ipatasertib, an AKT inhibitor, combined with HP, with or without endocrine therapy as maintainance therapy, in patients with unresectable locally advanced or metastatic PIK3CAmut, HER2-positive breast cancer following first-line induction chemotherapy and HP. RESULTS:Seventeen patients were enrolled, with a median follow-up of 27.7 months. During the dose-selection phase, ipatasertib at 400 mg daily (21 days on and 7 days off) with standard HP was established as the recommended phase II dosage. This decision was based on the absence of dose-limiting toxicities in the first six patients treated at this dosage during the initial 28-day cycle, which constituted the primary endpoint. Grade 3 treatment-related adverse events (TRAE) occurred in seven patients (41.2%), most commonly diarrhea and nausea. Two (11.8%) reported four serious TRAE (diarrhea, vomiting, ischemic stroke, and pneumonitis, one case each) related to ipatasertib, from which they recovered. The confirmed overall response rate was 31.1% [95% confidence interval (CI), 12.1%-58.5%], clinical benefit rate 84.6% (95% CI, 53.7%-97.3%), and median progression-free survival 16.4 months (95% CI, 9.4-NR); 47.3% of patients were progression free at 18 months. CONCLUSIONS:These results support ipatasertib plus HP as a safe and promising maintenance strategy for HER2-positive breast tumors harboring PIK3CAmut.
Abstract Background This study evaluated the efficacy and safety of generic semaglutide compared with innovator Semaglutide in Indian adults with type 2 diabetes mellitus (T2DM). Methods This Phase 3, multicenter, randomized, active-controlled, non-inferiority trial enrolled 320 adults with T2DM inadequately controlled on metformin. Participants were randomized 1:1 to receive either generic semaglutide (Alkem laboratories Ltd.) or innovator Inj. semaglutide (Novo Nordisk) for 24 weeks in step-wise dose escalation from 0.25 mg/week to 2 mg/week. The primary endpoint was change in HbA1c from baseline to Week 24. Secondary endpoints included changes in fasting and post-prandial glucose, body weight, and proportion of patients achieving HbA1c < 7.0%. Safety assessments included adverse events, hypoglycemia, various laboratory parameters. Results Of 320 participants randomized, 313 completed the study. Baseline demographic and clinical characteristics were comparable between groups. At Week 24, both treatments achieved significant HbA1c reductions (mean − 2.20%), with generic semaglutide demonstrating non-inferiority to the reference. Reductions in body weight, fasting and post-prandial glucose were similar between arms. A total of 86.62% of participants achieved HbA1c < 7.0%. Safety profiles were comparable, with predominantly mild-to-moderate adverse events and no treatment-related serious adverse events. Conclusion Generic semaglutide demonstrated non-inferior efficacy and comparable safety to innovator Semaglutide in Indian adults with T2DM inadequately controlled on metformin, offering an effective and accessible therapeutic option in resource-limited settings.
