Eligibility Criteria
Inclusion
- Men who meet all the following criteria are eligible for enrollment in the trial:
- Male volunteers in good health as confirmed by physical examination, medical history, and clinical laboratory tests of blood and urine at the time of screening.
- 18 to 50 years of age (inclusive) at the time of the enrollment visit.
- BMI ≤ 33 calculated as weight in kg/ (height in m2).
- No history of hormonal therapy use in the three months prior to the first screening visit.
- Subject agrees to use a recognized effective method of contraception with any female partner during the course of the study.
- Subjects agrees to refrain from donating blood or plasma during the study period and from participating in other investigational drug studies.
- Subjects agrees to refrain from excessive alcohol consumption during the study period. (No more than 15 drinks per week and no alcohol consumption within 24 hours of a study visit.)
- Subjects agrees to refrain from significant changes in their current exercise regimen during the drug exposure period.
- No known or suspected current alcohol dependence syndrome, chronic marijuana use, or any illicit drug use that may affect metabolism/transformation of steroid hormones and study treatment compliance.
- In the opinion of the investigator, subject can comply with the protocol, understand and sign an informed consent and HIPAA form.
Exclusion
- Men who meet any of the following criteria are NOT eligible for enrollment in the trial:
- Men participating in another clinical trial involving an investigational drug within 30 days prior to the first screening visit.
- Men not living in the catchment area of the clinic or within a reasonable distance from the study site.
- Clinically significant abnormal physical or laboratory findings at screening.
- Elevated PSA (levels ≥ 2.5 ng/mL) at screening, per local laboratory normal values.
- Abnormal serum chemistry values at screening, per local laboratory reference ranges that indicate liver or kidney dysfunction or that may be considered clinically significant. In addition, the following upper limits will be observed: fasting bilirubin less than 2 mg/dL, cholesterol less than 221 mg/dL, and fasting triglycerides less than 201 mg/dL.
- Abnormal semen analyses or abnormal semen concentration as defined by the WHO semen manual.
- Use of androgens within 3 months before the first screening visit except for long acting, intramuscular testosterone undecanoate which will require a wash out period of 6 months prior to randomization.
- Ongoing use of body building substances including nutritional supplements.
- Systolic BP \> 135 mm Hg and Diastolic blood pressure BP \> 85 and mm Hg; Blood pressure (BP) will be taken 3 times at 5 - minute intervals and the mean of all measurements be used to determine eligibility.
- Clinically significant abnormal EKG or a QTc interval of \> 450 msec.
- PHQ-9 score of 15 or above.
- History of hypertension, including hypertension controlled with medication.
- Known history of primary testicular disease or disorders of the hypothalamic-pituitary axis.
- Benign or malignant liver tumors, active liver disease or known non-alchoholic fatty liver disease (NAFLD)
- History of breast carcinoma.
- Known history of androgen deficiency due to hypothalamic-pituitary or testicular disease.
- Known history of cardiovascular, renal, hepatic or prostatic disease or significant psychiatric illness.
- Positive serology for active Hepatitis (not immunization-related serology) or HIV at screening visit.
- A serious systemic disease such as diabetes mellitus.
- History of known, untreated sleep apnea.
- Partner is known to be pregnant.
- Men desiring fertility within the first 24 weeks of study participation.
- 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) of a single dose.
- Subjects taking anticonvulsants.
- Subjects taking recombinant human growth factor (HGH).
- Subjects with a hematocrit greater than 55%.
- Previous participation in this clinical trial or any trials of 11-Beta MNTDC.
- Any site staff member with delegated study responsibilities or a family member of a site staff member with delegated study responsibilities.
