About this trial

This is an interventional treatment trial for Hypogonadism focused on measuring Healthy Adult Males

Eligibility Criteria

18 Years - 55 Years (Adult)MaleAccepts Healthy Volunteers

Inclusion Criteria:

  • Healthy adult male subjects, 18-55 years of age, inclusive, at the time of signing the informed consent;
  • Body weight ≥50 kg and body mass index within the range 19-30 kg/m2, inclusive, at screening;
  • Medically healthy subjects with clinically insignificant screening and check-in results (medical history, 12-lead electrocardiogram [ECG], physical examination, and laboratory tests); and
  • Subjects who are able to understand and are willing and able to give their signed informed consent before any trial-related procedures are performed.

Exclusion Criteria:

  • Currently diagnosed or a history of asthma, urticarial, angioedema, anaphylaxis, atopic dermatitis, clinically significant abnormality of skin of the abdomen, cancer, diabetes, or any other clinically significant cardiovascular, respiratory, metabolic, renal, hepatic, gastrointestinal, hematological, dermatological, venereal, neurological, psychiatric, or other major disorders;
  • History of benign prostate hypertrophy (BPH), prostate cancer, or abnormal prostate specific antigen (PSA) values;
  • PSA level > 3 ng/ml at screening;
  • Presence or history of gastrointestinal, hepatic or renal disease, or any other condition (including surgery) known to interfere with the absorption, distribution, metabolism, or excretion of medicines;
  • Systolic blood pressure outside the range of 90 to 140 mmHg, diastolic blood pressure outside the range of 40 to 90 mmHg, and/or pulse rate outside the range of 40 to 100 beats per minute after one repeat at screening or check-in;
  • Abnormal ECG at screening as judged by the Investigator;
  • History of clinically significant drug and/or food allergies as determined by the Investigator;
  • Allergy to sesame, sesame oil, or a history of hypersensitivity or idiosyncratic reaction to compounds related to the study drug
  • Subjects undergoing current treatment with other androgens (i.e. dehydroepiandrosterone [DHEA]), anabolic steroids, other sex hormones, or drugs that interfere with the metabolism of testosterone (i.e. opioids, anastrozole, clomiphene, dutasteride, finasteride, flutamide, ketoconazole, spironolactone, and testolactone);
  • Subjects treated within the past 12 months with estrogens, gonadotropin releasing hormone (GnRH) agonists, or growth hormone;
  • Prescription, over the counter medications, vitamins, herbal and dietary supplements taken within 7 days or 5 half-lives (whichever is longer) prior to the dose of study medication and duration of the study;
  • Positive screen for human immunodeficiency virus (HIV), hepatitis B, and/or hepatitis C at screening;
  • Positive urine screen for drugs of abuse (amphetamine, barbiturates, benzodiazepines, cocaine, marijuana, methadone, methamphetamines, oxycodone, and opiates) or positive breath alcohol test at screening and check-in

Arm Label

Testosterone enanthate auto-injector - 50 mg

Outcomes

Primary Outcome Measures

Maximum Concentration (Cmax) for Serum Testosterone and Testosterone Enanthate
Cmax = Maximum blood concentration (ng/dL) of TT=Total Testosterone and TE=Testosterone Enanthate
Area Under the Concentration-time Curve From Time Zero to Time t
AUC(0-168h) (ng⋅hr/dL) = area under the concentration-time curve from time zero to Day 8 (1 week);
Area Under the Concentration-time Curve From Time Zero to Infinity
AUC(0-inf) (ng⋅hr/dL) = area under the concentration-time curve from time zero to infinity

Secondary Outcome Measures

Time to Maximum Concentration (Tmax)(hr)
tmax = Time to reach maximum concentration
Half-life (t 1/2)(hr)
t 1/2 = Half-life is the time required for a concentration to reduce to half its initial value
Clearance CL/F (L/hr)
Clearance - volume of plasma from which TT/TE is completely removed per unit time
Vd/F (L)
Vd/F (L) = Apparent volume of distribution
