Summary

Single-arm, single site, open label study of the effects of parenteral testosterone followed by enzalutamide, abiraterone or castration-only therapy in men with metastatic CRPC who previously progressed on one of these forms of therapy. The study will enroll four cohorts of patients: men with metastatic CRPC who have progressed on enzalutamide (Cohort A; n=30); men with metastatic CRPC who have progressed on abiraterone acetate (Cohort B; n=30); men with metastatic CRPC who have progressed on first line castration-only therapy (Cohort C; n=30); men with metastatic CRPC with inactivating somatic or germline mutations in ≥2 of the genes TP53, PTEN, or RB1 (Cohort D; n=20).

Conditions

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 and will be administered at 400mg IM every 28 days.

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. Will be administered at 400mg IM every 28 days.

DRUG

Abiraterone acetate

Abiraterone is an inhibitor of CYP17 (17α-hydroxylase/C17,20-lyase). Each ZYTIGA tablet contains 250 mg of abiraterone acetate.

DRUG

Enzalutamide

XTANDI is provided as liquid-filled soft gelatin capsules for oral administration. Each capsule contains 40 mg of enzalutamide as a solution in caprylocaproyl polyoxylglycerides.
