Galeterone for Castration Resistant Prostate Cancer (ARMOR2)
ARMOR2: A 2 Part, Phase 2 Trial of Galeterone in the Treatment of Castration Resistant Prostate Cancer
Status Conditions Phase Study ID
Closed Prostate Cancer Phase II NCT01709734

A Phase 2, 2 part trial to evaluate the safety and efficacy of galeterone in castration resistant prostate cancer (CRPC) patients.

This trial will be split into two parts. The purpose of Part 1 will be to confirm dose and target patient population and Part 2 will be expansion of the dose and patient population selected in Part 1. For eligible patients, there will be an optional extension dosing following the completion of Part 1 or Part 2 of the trial.

Obtaining of informed consent and screening may be performed up to 28 days prior to enrollment. Each patient will be able to receive his specified regimen for 3 consecutive cycles. Each cycle consists of 28 days (approximately 1 mo.). End of Cycle 3 visit assessments will be used to determine outcome and dosing may continue up to an additional 2 weeks until the results of all assessments are obtained. Eligible patients may continue treatment in an optional extension period following the completion of the primary parts of this trial.
