NCT ID NCT06609005

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests a new drug called INV-9956 in 84 men with advanced prostate cancer that has spread and stopped responding to hormone therapy and chemotherapy. The goal is to find a safe dose and see if the drug can shrink tumors or slow the disease. Participants take INV-9956 along with two other medicines to manage side effects.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

INV-9956 (given with dexamethasone and fludrocortisone acetate)

What this could lead to

If it works, this could offer a new treatment option for men with advanced prostate cancer that has stopped responding to standard therapies.

What could go wrong

This is an early-phase trial with only 84 participants, so the drug may not prove effective or may have unexpected side effects. It is not a cure and long-term benefits are uncertain.
