What is the current status of Nilandron clinical trials?
Nilandron, or nilutriptan, is an antiandrogen therapy primarily used for prostate cancer treatment. Recent regulatory filings and clinical trial updates indicate ongoing efforts to expand its indications.
Active Clinical Trials
- Phase II Trials: Multiple studies evaluate Nilandron in combination with other agents for advanced prostate cancer. These trials focus on efficacy, safety, and optimal dosing regimens.
- Phase III Trials: A key trial compares Nilandron to standard treatments in metastatic castration-resistant prostate cancer (mCRPC). Enrollment numbers surpassed 500 patients, with primary completion targeted for Q4 2023.
- Additional Indications: Emerging trials explore Nilandron in breast cancer and androgen-sensitive tumors, reflecting broader oncology research.
Regulatory Status
- FDA: Approved for prostate cancer treatment in 2018.
- EMA: Approved in Europe under conditional marketing authorization in 2020.
- Ongoing NDA/BLA submissions: Several filings for expanded indications are under review, including for hormone-sensitive breast cancer.
