November 4, 2026 updated by: Chiesi Farmaceutici S.p.A.

A 12-Month Randomized, Multicenter, Double-Blind, Placebo-Controlled Phase 3 Study to Evaluate the Safety and Efficacy of Daily Subcutaneous Metreleptin Treatment in Subjects With Partial Lipodystrophy

This is a Phase III, double-blind, placebo-controlled, safety and efficacy study of daily SC metreleptin in subjects with Partial Lipodystrophy.

Detailed Description

This Phase 3, randomised, multicentre, double-blind, placebo-controlled study is designed to evaluate the safety and efficacy of once-daily subcutaneous metreleptin in participants with partial lipodystrophy and associated metabolic complications. The study compares metreleptin with placebo over a 12-month treatment period, followed by an extension phase. The primary objective is to assess the effect of metreleptin on key metabolic parameters, including glycaemic control and hypertriglyceridemia.

Secondary objectives include evaluation of safety, tolerability, additional metabolic outcomes, liver-related parameters, and patient-reported outcomes in this rare disease population.
