Effects of Tesamorelin (TH9507), a Growth Hormone-Releasing Factor Analog, in Human Immunodeficiency Virus-Infected Patients with Excess Abdominal Fat: A Pooled Analysis of Two Multicenter, Double-Blind Placebo-Controlled Phase 3 Trials with Safety Extension Data

Context: HIV patients treated with antiretroviral therapy (ART) often develop increased visceral adipose tissue (VAT). Objective: Our objective was to perform a pooled analysis of two phase-3 studies of tesamorelin in ART-treated HIV patients with excess abdominal fat. Design and Setting: Two multicenter, international studies were conducted; a 26-wk randomized, placebo-controlled primary intervention phase was followed by a 26-wk safety extension. Patients: A total of 806 ART-treated HIV patients with excess abdominal fat were randomized in a 2:1 fashion to receive tesamorelin 2 mg (n = 543) or placebo (n = 263) sc daily. At wk 26, patients initially on tesamorelin were rerandomized to 2 mg tesamorelin (T-T group, n = 246) or placebo (T-P, n = 135) for an additional 26 wk, whereas patients on placebo were switched to tesamorelin (P-T, n = 197). Interventions: Tesamorelin (GHRH1–44) at a dose of 2 mg or identical placebo, sc, was given daily. Main Outcome Measure: We evaluated percent change in VAT by com...
