Impact of Pain From Injectables Antiretroviral Treatments in HIV-1 Patients Based on the Injection Site (Ventrogluteal or Dorsogluteal) and the Use or Non-use of Virtual Reality Headset

Five visits will be performed as a standard of care: Inclusion visit: After checking of the eligibility, patient is informed of the study and an informed note is given. Injection site is examined. If the patient agrees, consent is collected. Visit D0 (all the patients): examination of the injection zone by the nurse, collection of concomitant treatments (only analgesics and anti-inflammatory drugs) taken by the patient, CAB+RPV injections according to the randomization arm, completion of the numerical scale by the patient following ARV injections, submission of the patient log for the assessment of pain by the patient during the 7 days following the ARV injections. Follow-up visits (M1, M3, M5 for naïve patients and M2, M4, M6 for treatment-experienced patients): recovery of the patient log with assessment of pain on previous injection, collection of concomitants treatments and adverse events, examination of the injection site by the nurse, injection according the randomization arm, completion of the numerical scale by the patient following the injections, delivery of a new patient note. End of study visit: recovery of the patient log with assessment of pain on previous injection, collection of concomitants treatments and adverse events, questioning the study procedures, patient's preferred choice between the different injection procedures. For the research needs, * The injection site (ventrogluteal and dorsogluteal) will be chosen, by randomisation * Wearing a virtual reality headset A patient log to assess pain, using a numerical scale (1 to 10), will be filled out by the patient
