Can a new pill outsmart resistant prostate cancer?
NCT ID NCT03436485
First seen Aug 14, 2026 · Last updated Aug 14, 2026
Summary
This trial is testing an experimental oral drug called ODM-208 in men with metastatic castration-resistant prostate cancer, a type of prostate cancer that has spread and no longer responds to standard hormone therapy. The main goal is to find the highest safe dose and to assess the drug's safety and how the body processes it. Participants take ODM-208 daily along with other medications to manage side effects. The study aims to determine if this drug can be a viable treatment option for this challenging condition.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ODM-208, an oral drug, taken daily with glucocorticoid and fludrocortisone
- What this could lead to
- If successful, this could lead to a new treatment option for men with advanced prostate cancer that has stopped responding to standard hormone therapies.
- What could go wrong
- This is an early-phase trial, so the drug may not be effective or may cause significant side effects. The results are preliminary and need further validation.

Main Inclusion Criteria: * Written informed consent (IC) obtained. * Male aged ≥ 18 years. * Histologically confirmed adenocarcinoma of the prostate. * Castration resistant prostate cancer with serum testosterone \< 50 ng/dl. * Metastatic disease. * Ongoing androgen deprivation therapy with GnRH analogue or antagonist, or have had bilateral orchiectomy. * Received at least one prior line of novel hormonal androgen receptor (AR) targeted therapy (e.g. abiraterone, enzalutamide). * ECOG performance status 0-1. * Adequate marrow, liver and kidney function. * Able to swallow study treatment. * Part 1: Treatment with at least 1 line of chemotherapy or ineligibility for chemotherapy. Part 2: Treatment with at least 1 line of taxane-based chemotherapy in castration-sensitive prostate cancer (CSPC) or in CRPC. Main Exclusion Criteria: * History of pituitary or adrenal dysfunction. * Known brain metastases or active leptomeningeal disease. * Active infection or other medical condition that would make corticosteroid contraindicated. * Poorly controlled diabetes. * Hypotension or uncontrolled hypertension. * Clinically significantly abnormal serum potassium or sodium level. * Active or unstable cardio/cerebro-vascular disease including thromboembolic events. * Prolonged QTcF interval.
