Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This study will evaluate the tolerability and acceptability of injection site reactions (ISRs) of two long-acting (LA) injectables. Additional characteristics of the ISRs will be investigated and described as well as safety outcomes.

Inclusion Criteria	Exclusion Criteria
1. At the time of obtaining informed consent, 18 years of age. 2. Body weight 50 kg and BMI within the range 18 to 32 kg/m2 (inclusive). 3. Participants who are overtly healthy as determined by medical evaluation by a responsible and experienced physician, including medical history, physical examination, laboratory tests and cardiac monitoring. 4. A participant with a significant clinical abnormality or laboratory parameter(s) which is/are not specifically listed in the inclusion or exclusion criteria, outside the reference range for the population being studied may be included if the investigator determines and documents that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures. A single repeat of a procedure or lab parameter is allowed to determine eligibility. 5. Male or female at birth (transgender individuals are not excluded but LEN may interfere with gender affirming hormones including increasing thrombotic risk. This should be discussed with Medical Monitor). 6. All participants are expected to use barrier methods for HIV/STI prevention and should be counselled accordingly at all visits. 7. Contraceptive use by men and women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. 8. Participants assigned female at birth are eligible to participate if they are not pregnant or breast/chest-feeding, and at least 1 of the following conditions applies: * Is not a person of childbearing potential (POCBP) OR * Is a POCBP and using a contraceptive method that is highly effective, with a failure rate of \<1%. The investigator should evaluate the effectiveness of the contraceptive method in relationship to the first dose of study intervention. 9. A POCBP must have a negative highly sensitive pregnancy test (urine and/or serum as required) within the 21 days before the dose of study intervention. 10. Must be capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol.	1. History or presence of cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrine, hematologic, or neurological disorders capable of significantly altering the absorption, metabolism, or elimination of drugs; constituting a risk when taking the study intervention or interfering with the interpretation of data. The investigator may contact the ViiV healthcare (VH) medical monitor to discuss the inclusion of participants who have a history of specific conditions that are not expected to interfere with their participation in the study. 2. Suspected or known active, serious infection(s). 3. Abnormal blood pressure as determined by the investigator. 4. History of any malignancy within the past 5 years. Exceptions are squamous and basal cell carcinomas of the skin and carcinoma in situ of the cervix, or malignancy which is considered cured with minimal risk of recurrence. Participants under evaluation for possible malignancy are not eligible. 5. Breast cancer within the past 10 years 6. Current or chronic history of liver disease or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones). 7. The participant has an underlying skin disease or disorder (i.e., infection, inflammation, dermatitis, eczema, drug rash, drug allergy, psoriasis, food allergy, urticaria) that would interfere with assessment of injection sites. 8. Current or anticipated need for chronic anti-coagulation. 9. Participants considered to have insufficient musculature to allow safe intramuscular (e.g., gluteus medius, vastus lateralis) or sufficient subcutaneous thickness to allow subcutaneous administration in the opinion of the investigator. 10. Any Positive Treponeme Specific Serologic testing (positive T. Pallidum antibody immunoassay + Rapid plasma reagin \[RPR\] or positive T. Pallidum antibody immunoassay + Treponema pallidum particle agglutination \[TPPA\]) is exclusionary. 11. Presence of HBsAg, or positive hepatitis C antibody test result at Screening or within 3 months prior to first dose of study treatment. 12. Have a history of osteoporosis or bone fragility fractures. 13. Participants who, in the investigator's judgment, poses a significant suicidality risk. Participant's history of suicidal behaviour and/or suicidal ideation should be considered when evaluating for suicide risk. 14. Any preexisting physical or mental condition which, in the opinion of the Investigator or the Medical Monitor, may interfere with the participant's ability to comply with the dosing schedule and/or protocol evaluations or which may compromise the safety of the participant. 15. Participants receiving any protocol-prohibited medication and who are unwilling or unable to switch to an alternate medication. 16. Treatment with any of the following agents within 60 days of screening: radiation therapy, cytotoxic chemotherapeutic agents, any systemic immune suppressant. 17. Past or intended use of over-the-counter or prescription medication including herbal medications within 7 days prior to dosing. 18. Use of glucocorticoids (through any route). 19. Exposure to more than 4 new investigational products within 12 months prior to the first dosing day. 20. Current enrolment or past participation in another investigational study in which an investigational intervention (e.g., drug, human blood product, monoclonal antibody, vaccine, invasive device) was administered within 1 month, 5 half-lives or twice the duration of the biological effect of the test agent prior to screening (whichever is longer). 21. Any acute laboratory abnormality at Screening, which, in the opinion of the investigator, would preclude the participant's participation in the study of an investigational compound. 22. Any verified Grade 4 laboratory abnormality, with the exception of Grade 4 triglycerides or lipid abnormalities. A single repeat test is allowed during the screening period to verify a result. 23. ALT greater than or equal to (\>=) 1.5x ULN. A single repeat test is allowed within a single Screening period to determine eligibility. 24.

A single repeat test is allowed within a single screening period to determine eligibility. 25. Creatinine clearance (eGFR) of \<60 mL/min/1.73 m2 via CKD-EPI method. 26. Positive HIV antibody/antigen test (HIV-1, HIV-2) at screening or enrolment. Participants will be advised regarding safer sex. In the event a participant acquires HIV during the study they will be required to withdraw from the study and will be referred urgently to an HIV treatment center for further management. 27. Clinically significant cardiovascular disease, as defined by history/evidence of congestive heart failure, symptomatic arrhythmia, angina/ischemia, coronary artery bypass grafting surgery or percutaneous transluminal coronary angioplasty or any clinically significant cardiac disease. 28. Grade 3 or Grade 4 proteinuria or glycosuria at screening that is unexplained or not clinically manageable. 29. Participant is unlikely to adhere to the study procedures, keep appointments, is planning to relocate during the study, or remain on study through to its conclusion. 30. Alcohol or substance use that, in the opinion of the study investigator and medical monitor, would interfere with the conduct of the study (e.g., provided by self-report, or found upon medical history and examination or in available medical records). 31. Participant has an implant/enhancement (including fillers) at the area of proposed injection; or tattoo or other dermatological condition overlying the area for IM or SC injection (e.g., gluteus medius, vastus lateralis or anterior abdominal wall) or any other area which may significantly interfere with interpretation of injection site reactions.
