Gosipol (GOSSYPOL)

Phase 3 active Small molecule

Gosipol (generic name: GOSSYPOL) is a gossypol drug. It is currently in Phase 3 development.

Gossypol works by binding to and inhibiting the Bcl-2 protein, which is involved in regulating cell death.

Gossypol, also known as GOSSYPOL, is a small molecule drug that targets the apoptosis regulator Bcl-2. It is a member of the gossypol drug class and was originally developed by. However, its current owner is unknown. Gossypol has not been approved by the FDA for any indications, and its commercial status, including whether it is patented or generic, is also unknown.

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.

Mechanism of action

Think of Bcl-2 as a guardian that helps keep cells alive. Gossypol is like a key that locks the guardian in place, preventing it from doing its job and allowing the cell to die. This can be helpful in treating certain types of cancer.
