Leuprolide acetate - Formulation A

Abbott · Phase 3 active Small molecule

Leuprolide acetate - Formulation A is a GnRH agonist Small molecule drug developed by Abbott. It is currently in Phase 3 development for Advanced prostate cancer, Endometriosis, Uterine fibroids (leiomyomata). Also known as: Lupron, leuprorelin, gonadotropin hormone-releasing hormone (GnRH), luteinizing hormone-releasing hormone (LHRH).

Leuprolide acetate is a gonadotropin-releasing hormone (GnRH) agonist that suppresses luteinizing hormone and follicle-stimulating hormone, leading to decreased testosterone and estrogen production.

Likelihood of approval
61.3% vs 58.3% industry baseline
If approved by FDA: likely 2028–2030
Steps remaining: NDA/BLA submission
Confidence: High
Why this estimate
  • Baseline phase 3 → approval rate +58.3pp
    Industry-wide phase 3 drugs reach approval ~58.3% of the time (BIO/Informa 2023 industry benchmark across all therapeutic areas).
  • Oncology Phase 3 boost +3.0pp
    Oncology Phase 3 trials have higher approval rates (~61%) than the cross-industry average due to clearer endpoints and FDA oncology pathway.
Predicted approval windows by jurisdiction (conditional on FDA approval)
Regulator Country Likely year Lag vs FDA
FDA US 2028–2030
EMA EU 2029–2031 +0.7 yr
MHRA GB 2029–2031 +0.7 yr

Mechanism of action

Leuprolide works by binding to GnRH receptors in the pituitary gland, initially causing a surge in gonadotropin release followed by sustained suppression of LH and FSH through receptor desensitization. This results in profound suppression of sex hormone production, making it effective for hormone-dependent conditions such as prostate cancer, endometriosis, and uterine fibroids.
