Trial overview
Official title: A Randomized Double Blinded (Sponsor Unblind), Placebo-Controlled Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of the Selective Androgen Receptor Modulator (SARM) in Single and Repeat Doses in Healthy Male Subjects
Trial description: This study is the first administration of GSK2881078 to humans. The intention of this study is to provide sufficient confidence in the safety of the molecule to inform progression to further repeat dose and proof of concept studies. This study will include approximately 52 subjects and consist of 2 parts. Part A will consist of two cohorts of 8 subjects to assess the safety, tolerability, and pharmacokinetic (PK) of ascending single oral doses of GSK2881078. Cohorts 1 and 2 will include healthy male subjects. Part B (Cohorts 3, 4 and 5) will include three cohorts of 12 healthy male subjects to examine the safety, tolerability, PK, and pharmacodynamic (PD) of repeated doses of GSK2881078 over 14 days. The total duration of the study including screening and follow-up, is not expected to exceed 70 days.

Accepts healthy volunteers
Yes
- Males between 18 and 50 years of age (inclusive), at the time of signing the informed consent form
- Body weight >= 50 kilogram (kg) and Body Mass Index (BMI) within the range 19 - 32 kg/meter square (m^2) (inclusive), where BMI= weight in kg/ height in m^2
- Subjects with a history of clinically significant endocrine, gastrointestinal, hepatic, cardiovascular, neurological, haematological, immunological, renal, respiratory, or genitourinary abnormalities or diseases.
- Subjects with a history at any time in the past of coronary artery disease, congestive heart failure, angina, myocardial infarction, any cardiac surgery, valvular heart disease, clinically significant arrhythmia, dyspnea, pulmonary edema, stroke, or transient ischemic attack. ECG exclusion criteria: Heart rate-<40 and >100 beats per minute, PR Interval-<120 and >200msec, QRS duration-<70 and >110msec.
Inclusion and exclusion criteria
Inclusion criteria:
- Males between 18 and 50 years of age (inclusive), at the time of signing the informed consent form
- Body weight >= 50 kilogram (kg) and Body Mass Index (BMI) within the range 19
- 32 kg/meter square (m^2) (inclusive), where BMI= weight in kg/ height in m^2
- Healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring. A subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included only if the Investigator and the GSK Medical Monitor agree that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
- Male subjects with female partners of child-bearing potential must agree to use one of the contraception methods listed in the Lifestyle Section of the protocol. This criterion must be followed through the completion of the follow-up visit.
- Average QTcF <450millisecond (msec); or QTcF <480msec in subjects with Bundle Branch Block.
- Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
Exclusion criteria:
- Subjects with a history of clinically significant endocrine, gastrointestinal, hepatic, cardiovascular, neurological, haematological, immunological, renal, respiratory, or genitourinary abnormalities or diseases.
- Subjects with a history at any time in the past of coronary artery disease, congestive heart failure, angina, myocardial infarction, any cardiac surgery, valvular heart disease, clinically significant arrhythmia, dyspnea, pulmonary edema, stroke, or transient ischemic attack. ECG exclusion criteria: Heart rate-<40 and >100 beats per minute, PR Interval-<120 and >200msec, QRS duration-<70 and >110msec.
