Brief Summary:
This is a Phase I multicenter, double-blind, single dose, dose-ranging study, in healthy men to evaluate the safety and tolerability, pharmacokinetics and pharmacodynamics of Dimethandrolone Undecanoate (DMAU) administered as an intramuscular or subcutaneous injection.

Condition or disease Intervention/treatment Phase
Healthy Men Male Contraception Drug: Dimethandrolone Undecanoate Drug: Placebo Phase 1

Detailed Description:

This single dose, dose-ranging study will be conducted in two centers: the Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Center and the University of Washington.

Single doses of DMAU in castor oil/benzyl benzoate injections intramuscularly (IM) (80 mg, 240 mg, 480 mg, and 800 mg) or administered subcutaneously (SC) (50 mg, 100 mg and 200 mg) were selected for this dose-escalating study. Twelve subjects will complete this study at each of the DMAU doses (10 on DMAU and 2 on placebo injections) yielding a total of 84 completed subjects (70 on DMAU and 14 on placebo) across both sites. Safety will be assessed in all subjects and recovery will be assessed in two subjects receiving lower doses, either IM or SC, before additional men receive higher doses of IM or SC of DMAU. In addition to safety and tolerability, suppression of serum T, E2, gonadotropins, and SHBG will be assessed as secondary pharmacodynamic (PD) endpoints. PK of DMAU and DMA will be assessed through blood draws done at each visit. Suppression of spermatogenesis will be assessed with semen analysis.

DMAU injections will be administered at the study site by research nurses or physicians. For intramuscular injections, the staff will inject DMAU in castor oil into the gluteal region following standard procedures for intramuscular steroid injection. Abdominal subcutaneous injections will follow standard subcutaneous procedures. The subject will be observed for at least 30 minutes before release from the study site.

22. Partner is known to be pregnant. 23. Men desiring fertility within the first seven months of study participation.

24. Men participating in competitive sports where drug screening for prohibited substances (including anabolic steroids) is routine. Exclusion is due to the potential of testing positive for androgens that may occur from their study participation coupled with the unknown efficacy (i.e. duration of positive testing) from a single injection.

26. Use of sex steroids or medications which might interfere with steroid metabolism (i.e. ketoconazole, finasteride, oral corticosteroids, dutasteride and statins).
