    TLDR Gestrinone pellets may help reduce pelvic pain in endometriosis safely.
    The GLADE study is a randomized, multicenter, double-blind, placebo-controlled trial involving 100 participants with deep infiltrative endometriosis who did not respond satisfactorily to surgery. It evaluates the safety and efficacy of gestrinone subdermal bioabsorbable pellets for treating endometriosis-related pelvic pain. Participants receive either gestrinone pellets or a placebo, alongside a levonorgestrel-releasing intrauterine system, over 6 months. The primary endpoint is the occurrence of serious adverse events, while secondary outcomes include androgenization effects, changes in pelvic pain intensity, and quality of life. The study aims to provide insights into the safety, tolerability, and pharmacokinetics of gestrinone pellets, potentially informing clinical practice for endometriosis treatment.
