Introduction

Linzagolix, brand named Yselty®, is a selective, orally administered, non-peptide small molecule gonadotrophin-releasing hormone (GnRH) receptor antagonist developed by Kissei Pharmaceutical, aimed at treating uterine fibroids and endometriosis in women of reproductive age​1​. Here is an in-depth insight into Linzagolix’s pharmacology, along with some recent updates:

IntroductionMechanism of ActionTherapeutic UsesRecent UpdatesConclusion

Mechanism of Action

Linzagolix operates by binding to and blocking the GnRH receptor located in the pituitary gland. This interaction modulates the hypothalamic-pituitary-gonadal axis, leading to a dose-dependent reduction in the serum levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), as well as serum estradiol levels​1​.

Therapeutic Uses

Uterine Fibroids: Linzagolix has been approved in the European Union for treating moderate to severe symptoms of uterine fibroids in adult women of reproductive age. This approval extends the treatment options available for managing this condition, offering different treatment regimens, including short-term use to reduce uterine and fibroid volumes​2​.

Endometriosis-Associated Pain: Linzagolix is in phase 3 clinical development for managing pain associated with endometriosis, showcasing its potential in broadening the therapeutic options for this debilitating condition​1​.

Recent Updates

  • Approval: As of June 2022, Linzagolix received approval in the EU for the treatment of moderate to severe symptoms of uterine fibroids in adult women of reproductive age. Additionally, it is under regulatory review in the USA for the same indication​1​.
  • Clinical Trials: Recent clinical trials, including a randomized, double-blind, placebo-controlled trial, investigated the long-term efficacy and safety of Linzagolix in 484 women with moderate to severe Endometriosis-Associated Pain (EAP). The trial evaluated two dose regimens: Linzagolix 200 mg once daily in combination with hormonal add-back therapy (ABT) and Linzagolix 75 mg without ABT​3​.
  • Reduced Menstrual Bleeding: Recent studies found that Linzagolix (100 mg or 200 mg) with or without add-back therapy significantly reduced heavy menstrual bleeding, showcasing its potential benefits in managing symptoms associated with uterine leiomyomas​4​.

Conclusion

Linzagolix’s development, clinical trials, and recent approval in the EU reflect the ongoing efforts to provide better therapeutic solutions for women suffering from uterine fibroids and endometriosis. Its mechanism of action, which centrally modulates the hormonal axis, holds promise in offering a valuable treatment option for these prevalent gynecological conditions.
