A Bioequivalence Study of Testosterone Cypionate in Hypogonadal Males
A PHASE 1, OPEN-LABEL, RANDOMIZED, 2-TREATMENT SINGLE-DOSE, CROSS-OVER STUDY, 2-PART DESIGN TO EVALUATE THE BIOEQUIVALENCE AND TOLERABILITY OF TESTOSTERONE CYPIONATE FOLLOWING INTRAMUSCULAR (IM) INJECTION IN HEALTHY HYPOGONADAL MALE SUBJECTS

Brief Summary
This is an open-label, 2-treatment, 2-period, single dose (200 mg, IM) cross-over study, 2-part design to evaluate the bioequivalence (BE) of a reformulated presentation (test) of testosterone cypionate solution for injection relative to the currently approved marked formulation (reference). In the first part of the study (Part 1), an estimate of the exposure variability will be evaluated for both test and reference. This will help guide sample size in Part 2. Part 2 will be powered to assess the BE of both test and reference formulations.

Primary Outcomes (6)
Corrected Area Under The Serum Concentration-time Profile From Time 0 to The Last Quantifiable Concentration (AUClast) of Total Testosterone (Part 1).
The AUClast of total testosterone in Part 1 of the study was observed directly from data. The baseline endogenous testosterone level was the mean of the 4 predose PK samples, an average baseline correction of endogenous total testosterone levels was calculated.

Eligibility Criteria
You may qualify if:
- Hypogonadal male subjects who, at the time of screening, are otherwise healthy and between the ages of 18 and 65 years, inclusive. Healthy is defined as no clinically relevant abnormalities identified by a detailed medical history, full physical examination, including blood pressure (BP) and pulse rate measurement, 12 lead electrocardiogram (ECG), or clinical laboratory tests.
- Hypogonadism is defined as serum testosterone levels below 2.5 ng/mL (250 ng/dL).
- Body mass index (BMI) of 17.5 to 35 kg/m2; and a total body weight \>50 kg (110 lb).
- Evidence of a personally signed and dated informed consent document indicating that the subject has been informed of all pertinent aspects of the study.
- Subjects who are willing and able to comply with all scheduled visits, treatment plan, laboratory tests, and other study procedures.
You may not qualify if:
- Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurological, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at the time of dosing).
- Subjects who are currently being treated for hypogonadism. This is defined as either patients who have received a testosterone injectable product within the past 3 months or have used a transdermal or gel product within the past 2 weeks.
- A positive urine drug test.
- History of regular alcohol consumption exceeding 14 drinks/week (1 drink = 5 ounces \[150 mL\] of wine or 12 ounces \[360 mL\] of beer or 1.5 ounces \[45 mL\] of hard liquor) within 6 months before screening.
- Treatment with an investigational drug within 30 days (or as determined by the local requirement) or 5 half lives preceding the first dose of investigational product (whichever is longer).
- Screening supine BP greater than or equal to 140 mm Hg (systolic) or greater than or equal to 90 mm Hg (diastolic), following at least 5 minutes of supine rest. If BP is greater than or equal to 140 mm Hg (systolic) or greater than or equal to 90 mm Hg (diastolic), the BP should be repeated 2 more times and the average of the 3 BP values should be used to determine the subject's eligibility.
- Screening supine 12 lead ECG demonstrating a corrected QT (QTc) interval \>450 msec or a QRS interval \>120 msec. If QTc exceeds 450 msec, or QRS exceeds 120 msec, the ECG should be repeated 2 more times and the average of the 3 QTc or QRS values should be used to determine the subject's eligibility.
- Subjects with ANY of the following abnormalities in clinical laboratory tests at screening, as assessed by the study-specific laboratory and confirmed by a single repeat test, if deemed necessary:
- Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) level greater than or equal to 3 times the upper limit of normal (ULN).
- Total bilirubin level greater than or equal to 1.5 times the ULN; subject with a history of Gilbert's syndrome may have direct bilirubin measured and would be eligible for this study provided the direct bilirubin level is less than or equal to ULN.
- Fertile male subjects who are unwilling or unable to use a highly effective method of contraception as outlined in this protocol \[Contraception (Section 4.3.4)\] for the duration of the study and for at least 45 days after the last dose of investigational product.
- Use of prescription or nonprescription drugs and dietary supplements within 7 days or 5 half lives (whichever is longer) prior to the first dose of investigational product. As an exception, acetaminophen/paracetamol may be used at doses of greater than or equal to 1 g/day. Limited use of nonprescription medications that are not believed to affect subject safety or the overall results of the study may be permitted on a case by case basis following approval by the sponsor.
- Blood donation (excluding plasma donations) of approximately 1 pint (500 mL) or more within 56 days prior to dosing.
- History of human immunodeficiency virus (HIV), hepatitis B, or hepatitis C; positive testing for HIV, hepatitis B surface antigen (HepBsAg), hepatitis B core antibody (HepBcAb), or hepatitis C antibody (HCVAb).
- History of sensitivity to heparin or heparin induced thrombocytopenia.
