Brief summary

The pre-exposure prophylaxis (PrEP) is an important component in the overall strategy for prevention of HIV infection. Cabotegravir (CAB) is an integrase strand transfer inhibitor currently in development for treatment and prevention of HIV infection. CAB possesses attributes that allow formulation and delivery as a LA parenteral product. CAB is being developed as both oral and long acting (LA) injectable formulations. This study is designed to evaluate the PK, safety, tolerability, and acceptability of CAB LA in adult HIV uninfected Chinese male subjects at low risk for HIV acquisition. Eligible subjects will receive oral CAB during oral phase of the study followed by CAB LA intramuscular (IM) injection during injection phase of the study. Approximately 60 subjects will be screened, of which, approximately 48 subjects will enter the oral phase and 40 subjects will enter the injection phase of the study. The maximum study duration will be approximately 89 weeks including oral phase, injection phase and follow-up phase.

Interventions

CAB tablet will be formulated as white to almost white, oval shaped, film coated 30 mg tablets, administered orally once daily. The CAB tablets will be packaged in bottles containing 30 tablets each.

DRUGCAB LA

CAB LA is a sterile white to slightly colored suspension containing 200 mg/mL of CAB as free acid for administration by IM injection in gluteus medius.

Total score was calculated by taking sum of scores of all questions. It ranges from -39 to 39, with higher scores indicating more satisfaction.

Chemistry parameters were graded according to DAIDS Table for Grading the Severity of Adult and Pediatric Adverse Events as Grade 0: none, Grade 1: mild; Grade 2: moderate; Grade 3: severe; and Grade 4: potentially life-threatening consequences. Higher grade indicates more severity. Clinical chemistry laboratory parameters included alanine amino transferase (ALT), albumin, alkaline phosphatase (ALP), Aspartate Aminotransferase (AST), bilirubin, calcium (hypercalcemia and hypocalcemia), carbon dioxide (CO2) (decreased), cholesterol (high), Creatine phosphokinase (CPK) increased, Creatinine increased, creatinine clearance (decreased), glucose (hyperglycemia and hypoglycemia), Hypophosphatemia, Potassium (Hyperkalemia and hypokalemia), Sodium (hypernatremia and hyponatremia), Hypertriglyceridemia, uric acid (increased). Baseline was the last available assessment prior to the time of the first dose. Maximum toxicity grade reached by a participant post-Baseline was summarized.

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study treatment, whether or not considered related to the study treatment. SAE is defined as any untoward medical occurrence that, at any dose results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent disability/incapacity, is a congenital anomaly/birth defect, or other situations as per investigator's judgement.

Number of Participants With Shift From Baseline in Vital Signs With Respect to Clinical Concern Range: Injection Phase

Vital signs were measured after participants had rested in supine position for at least 5 minutes. Clinical concern ranges were: systolic blood pressure (SBP) (Low: \<85 millimeters of mercury \[mmHg\], High: \>160 mmHg), diastolic blood pressure (DBP) (Low: \<45 mmHg, High: \>100 mmHg), pulse rate (Low: \<40 mmHg, High: \>100 mmHg). Worst case results are presented. Participants were counted in the worst case category that their value changes to (Low, Normal or High), unless there was no change in their category. Participants whose value category was unchanged (e.g., High to High), or whose value became normal, were recorded in the 'To Normal or No Change' category. Participants were counted twice if the participant had values that changed 'To Low' and 'To High', so the percentages may not add to 100%.

Time frame: Week 5 to 41

HIV-Prevention Treatment Satisfaction Total Score-Injection Phase

HIV-Prevention Treatment Satisfaction Questionnaire (change) (HIV-PrevTSQc) was used to assess participant tolerability and satisfaction to the treatment. It consisted total 13 questions. The experience of HIV prevention treatment was assessed using a scale from 3 (much more satisfied/effective/convenient/ flexible/likely to recommend the treatment/likely to speak well of the treatment/easier now) to -3 (much less satisfied/effective/convenient/flexible/likely to recommend the treatment/likely to speak well of the treatment/easier now). Total score was calculated by taking sum of scores of all questions. It ranges from -39 to 39, with higher scores indicating more satisfaction.

Number of Participants With Maximum Toxicity Post-Baseline in Hematology Parameters: Oral lead-in Phase

Hematology parameters were graded according to DAIDS Table for Grading the Severity of Adult and Pediatric Adverse Events as Grade 0: none, Grade 1: mild; Grade 2: moderate; Grade 3: severe; and Grade 4: potentially life-threatening consequences. Higher grade indicates more severity. Clinical hematology parameters included: APTT prolonged, Hb (increased), WBC (decreased), lymphocytes count (decreased), neutrophils (decreased), platelets (decreased), prothrombin international normalized ratio (Pro.INR) (increased). Baseline was the last available assessment prior to the time of the first dose. Maximum toxicity grade reached by a participant post-Baseline was summarized.

Number of Participants With Non-serious AEs and SAEs (Oral lead-in Phase)

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study treatment, whether or not considered related to the study treatment. SAE is defined as any untoward medical occurrence that, at any dose results in death, Is life-threatening, Requires inpatient hospitalization or prolongation of existing hospitalization, Results in persistent disability/incapacity, Is a congenital anomaly/birth defect, other situation as per investigator's judgement.

Time frame: Up to Week 4

Population: Safety Population. It comprised all participants who received at least 1 dose of the study treatment.

Number of Participants With Shift From Baseline in Vital Signs With Respect to Clinical Concern Range: Oral lead-in Phase

Vital signs were measured after participants had rested in supine position for at least 5 minutes. Clinical concern ranges were: SBP (Low \<85 mmHg, High: \>160 mmHg), DBP (Low: \<45 mmHg, High: \>100 mmHg), pulse rate (Low: \<40 mmHg, High: \>100 mmHg). Worst case results are presented. Participants were counted in the worst case category that their value changes to (Low, Normal or High), unless there was no change in their category. Participants whose value category was unchanged (e.g., High to High), or whose value became normal, were recorded in the 'To Normal or No Change' category. Participants were counted twice if the participant had values that changed 'To Low' and 'To High', so the percentages may not add to 100%.

Time frame: Up to Week 4
