- Brief Summary
The primary purpose of the study is to investigate the safety, tolerability, and pharmacokinetic (PK) profiles of two different cabotegravir formulations in healthy adult participants. The study will initially start with the assessment of Cabotegravir Formulation F. Once the clinical batch of Cabotegravir Formulation G is available, this formulation will be assessed.

- Regular alcohol consumption within 6 months prior to the study defined as an average weekly intake of >14 units for males or >7 units for females.
- Regular use of known drugs of abuse.
- Concurrent participation in another clinical trial (except imaging trials); or has participated in a clinical trial and received an investigational product within the following time period prior to the first dosing day in this study: 30 days, 5 half-lives or twice the duration of the biological effect of the investigational product (whichever is longer).
- Participation in the study would result in loss of blood or blood products in excess of 500 mL within 56 days.
- Exposure to more than four (4) new chemical entities within 12 months prior to the first dosing day.
- History of sensitivity to any of the study interventions (or components thereof), a history of drug allergy or other allergy that, in the opinion of the investigator or medical monitor, contraindicates their participation
- Current or anticipated need for chronic anti-coagulation therapy (with the exception of low-dose aspirin =< 325 mg/day)
- Hereditary coagulation and platelet disorders (e.g., haemophilia or Von Willebrand disease [VWD]).
- Participant has a tattoo overlying the location of injection or an underlying skin disease or condition (e.g., infection, inflammation, dermatitis, eczema, drug rash, drug allergy, psoriasis, food allergy, urticaria) that, in the opinion of the investigator, may interfere with interpretation of injection site reactions or administration of study intervention.
- Any other clinical condition, behaviour or prior therapy that, in the opinion of the investigator, would make the participant unsuitable for the study; unable to comply with dosing requirements; or unable to comply with study visits.
