Summary

Asymptomatic men with progressive metastatic Castration-resistant prostate cancer (CRPC) post- treatment with abiraterone acetate (pre-chemotherapy for metastatic disease) will be treated on a randomized, multi-Institutional open label study to determine if treatment with intramuscular T given on a dose/schedule designed to result in rapid cycling from the polar extremes of supraphysiologic to near castrate levels \[i.e. Bipolar Androgen Therapy (BAT)\] will improve primary and secondary objectives vs. enzalutamide as standard therapy.

Conditions

  • Castration Resistant Metastatic Prostate Cancer

Interventions

DRUG

Testosterone cypionate

Depo-Testosterone Injection, for intramuscular injection, contains testosterone cypionate which is the oil-soluble of the androgenic hormone testosterone. Testosterone cypionate is a white or creamy white crystalline powder, odorless or nearly so and stable in air. Depo-Testosterone Injection is available in two strengths, 100 mg/mL and 200 mg/mL testosterone cypionate.

DRUG

Enzalutamide

Enzalutamide is a white crystalline non-hygroscopic solid. It is practically insoluble in water. Enzalutamide is provided as liquid-filled soft gelatin capsules for oral administration. Each capsule contains 40 mg of enzalutamide as a solution in caprylocaproyl polyoxylglycerides. The inactive ingredients are caprylocaproyl polyoxylglycerides, butylated hydroxyanisole, butylated hydroxytoluene, gelatin, sorbitol sorbitan solution, glycerin, purified water, titanium dioxide, and black iron oxide.

DRUG

Testosterone Enanthate

Testosterone Enanthate Injection, for intramuscular injection, contains testosterone enanthate which is the oil-soluble ester of the androgenic hormone testosterone. Enanthate Injection is available as a colorless to pale yellow solution. Each mL contains 200 mg testosterone enanthate in sesame oil with 5 mg chlorobutanol as a preservative.
