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

The purpose of this study is to identify 1 or more doses of parenterally administered VH4524184 that are safe, well tolerated and yield a PK drug exposure profile necessary to deliver a long-acting antiretroviral therapy for the treatment of HIV-1 infection.

Capable of providing signed informed consent.	1. History or presence of clinical condition or disorder that could be capable of significantly altering the absorption, metabolism, or elimination of drugs; constituting a risk when taking the study drug, interfering with the interpretation of data or would make the participant unsuitable for the study; unable to comply with dosing requirements; or unable to comply with study visits. 2.

Presence of tattoos or skin piercings that may interfere with the administration of study product and/or assessment of ISRs, if they occur. 15.

Current enrollment or past participation in another investigational study in which an investigational intervention was administered within the last 30 days, 5 half-lives or twice the duration of the biological effect of the investigational product before signing of consent (OR screening) any other clinical study. 20. Participation in the study would result in loss of blood in excess of 500 mL over a 56-day period. 21. Current enrollment or past participation in this clinical study or prior participation in study 218803. 22. eGFR \<60 mL/min or serum creatinine \>1.1 x ULN. 23.

Positive pre-study drug/alcohol screen. 31. Positive HIV antibody test. Other Exclusions 32. 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. One unit is equivalent to 8 g of alcohol: a half-pint (\~240 ml) of beer, 1 glass (125 ml) of wine or 1 (25 ml) measure of spirits. 33. Regular use of known drugs of abuse. 34.
