Eligibility |
Inclusion Criteria: 1. Provide voluntarily agreement to participate in this study and sign an Independent Ethics Committee (IEC)-approved informed consent prior to performing any of the screening procedures. 2. Males of any ethnic origin, between 40 to 70 years of age (inclusive) at the screening visit. 3. Healthy, determined by pre-study medical evaluation (medical history, vital signs, physical examination, standard 12-lead ECG and clinical laboratory evaluations). If a vital sign or ECG assessment is outside of the reference range at the screening visit or admission, the assessment may be repeated once to rule out any error. 4. Body mass index (BMI) between 20.0 and 34.9 kg/m2 (inclusive) at the screening visit and on admission. Exclusion Criteria: 1. Clinically relevant history of cardiovascular, respiratory, hepatic, renal, pancreatic, gastrointestinal, metabolic, endocrine, neurological, dermatological, immunological, psychiatric or other diseases/disorders as determined by the Principal Investigator or designee, or evidence of such diseases/disorders during the screening period. 2. Any disorder or clinically relevant surgical history that would interfere with the absorption, distribution, metabolism or excretion of the study drug. 3. History of proneness to orthostatic dysregulation, fainting or blackouts. 4. History or physical evidence of chronic or clinically relevant acute infection. 5. Screening total testosterone <3.0 ng/mL (<10.4 nmol/L). 6. History of anaphylactoid reactions or hypersensitivity to teverelix or GnRH antagonists or any of the excipients of the products tested. 7. History of clinically relevant allergies or idiosyncrasies to medication or food. 8. History of regular alcohol consumption exceeding 21 units per week within 2 years of study entry. 9. History of illicit drug abuse within 2 years of study entry. 10. Any ECG abnormality of clinical relevance; ECG QT interval corrected for heart rate using Fridericia's correction (QTcF) > 450 ms at the screening visit. 11. Any clinically relevant findings in the laboratory tests, as judged by the Principal Investigator, at the screening visit and on admission; alanine aminotransferase (ALT) > 1.5 x the upper limit of normal (ULN) and/or aspartate aminotransferase (AST) > 1.5 x ULN and/or total bilirubin > 1.0 x ULN, as confirmed by subsequent repeat assessment, at the screening visit and on admission. If a laboratory assessment is outside of the reference range at the screening visit or admission, the assessment may be repeated once to rule out laboratory error. 12. An estimated glomerular filtration rate (eGFR) < 90 mL/min, based on creatinine clearance calculation by the Cockcroft Gault formula and normalised to an average surface area of 1.73m2, at the screening visit. 13. Positive results in any of the tests for hepatitis B surface antigen (HBsAg), total hepatitis B core antibody (HBcAb), hepatitis C antibody (anti-HCV) or human immunodeficiency virus (HIV) antibodies, at the screening visit. 14. Positive urine test for ethanol and/or drugs of abuse at the screening visit or admission. 15. Use of prescription, non-prescription and over-the-counter (OTC) medications (including vitamins or herbal remedies) within 2 weeks prior to dosing is prohibited. 16. Receiving an investigational product in a clinical trial within 3 months prior to the screening visit. 17. Donation of blood (> 500 mL) or blood products within 2 months (56 days) prior to the screening visit. 18. Unwilling to avoid consumption of coffee and caffeine-containing products within 48 hours prior to admission until discharge from the study centre, as well as from 48 hours before ambulatory visits. 19. Unwilling to avoid use of alcohol or alcohol-containing foods, medications or beverages, within 48 hours prior to admission until discharge from the study centre, as well as from 48 hours before ambulatory visits. 20. Unwilling to abstain from vigorous exercise from 72 hours prior to admission until discharge from the study centre, as well as from 72 hours before ambulatory visits. 21. Unable to understand the protocol requirements, instructions and study related restrictions, the nature, scope and possible consequences of the clinical study. 22. Subject is unlikely to comply with the protocol requirements, instructions and study related restrictions; e.g., uncooperative attitude, inability to return for follow-up visits and improbability of completing the clinical study. 23. Subject has any concurrent condition that, in the opinion of the Principal Investigator, would make the subject unsuitable for participation in the clinical study. 24. Subject is an employee or the close relative of an employee of the Sponsor or the clinical research organisation (CRO) involved in the clinical study. 25. Vulnerable subjects defined as individuals whose willingness to volunteer in a clinical study may be unduly influenced by the expectation, whether justified or not, of benefits associated with participation, or of a retaliatory response from senior members of a hierarchy in case of refusal to participate (e.g., persons in detention, minors and those incapable of giving consent). |
