A Safety, Tolerability, Acceptability, and Pharmacokinetic (PK) Study of Cabotegravir (CAB) in Healthy Human Immunodeficiency Virus (HIV)-Uninfected Chinese Men

Inclusion Criteria

• Subjects must be 18 to 65 years of age inclusive, at the time of signing the informed consent.
• Subjects are male at birth.
• Subjects who have non-reactive point of care (POC) HIV test and undetectable HIV-1 ribose nucleic acid (RNA) at screening.
• At risk of acquiring HIV, defined as having at least one casual male or female sex partner in the past 24 months.
• Healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring at the time of screening.
• Capable of giving written informed consent.
• Agree to appropriate use of contraceptive measures during heterosexual intercourse. All subjects should be counseled on safer sexual practices including the use and benefit/risk of effective barrier methods (example given (e.g.), male condom) to reduce the risk of sexually transmitted infections.
• Willing to undergo all required study procedures.

Exclusion Criteria

• Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
• History of the following cardiac diseases: myocardial infarction, congestive heart failure, documented hypertrophic cardiomyopathy, sustained ventricular tachycardia.
• Active skin disease or disorder (that is [i.e.], infection, inflammation, dermatitis, eczema, drug rash, psoriasis, urticaria). Mild cases of localized acne or folliculitis or other mild skin condition may not be exclusionary at the discretion of the Investigator of Record or Medical Monitor.
• Subjects determined by the Investigator to have a high risk of seizures, including subjects with an unstable or poorly controlled seizure disorder. A subject with a prior history of seizure may be considered for enrolment if the Investigator believes the risk of seizure recurrence is low. All cases of prior seizure history should be discussed with the Medical Monitor prior to enrolment.
• Any medical condition, including psychiatric conditions that in the judgment of the investigator would interfere with the subject's ability to complete study procedures.
• Subjects who, in the investigator's judgment, poses a significant suicide risk.
• Use of antiretroviral (ARV) therapy (e.g., for Post exposure prophylaxis [PEP] or PrEP) in the past 30 days.
• Use of high dose aspirin or any other anticoagulant or antiplatelet medication that would interfere with the ability to receive IM injections.
• Assessed by the Investigator of Record or designee as being at "high risk" for HIV infection. This may include one or more of the following: the negative partner in an HIV serodiscordant couple where the HIV infected partner is not suppressed; men who exchange sex for goods or money; men who have engaged in any condomless anal intercourse within the past 6 months; men who have had greater than 5 male or female sexual partners within the past 6 months; men who have had a sexually transmitted disease within the past 6 months; any other behavior assessed by the investigator as "high risk".
• History of drug or alcohol consumption that in the opinion of the Principal Investigator will interfere with study participation.
• Ongoing intravenous drug use - episodic use or any use in the past 90 days is exclusionary (as assessed by the study investigator).
• One or more reactive HIV test results at screening or enrolment, even if HIV infection is not confirmed. Negative HIV RNA must also be documented at screening.
• Co-enrolment in any other HIV interventional research study (provided by self-report or other available documentation) or prior enrolment and receipt of the active arm (i.e., NOT a placebo) of a HIV vaccine trial (provided by available documentation).
• Any of the following laboratory values during the screening period: positive hepatitis C antibody result; positive Hepatitis B surface antigen (HBsAg); hemoglobin 1.5 or a
