What this Trial Is About

For most people with HIV (PWH), an effective antiretroviral regimen can be devised. However, some PWH have multiple treatment failures due to viral resistance or unacceptable side effects to medication and no longer have durable viral suppression. People with multidrug-resistant HIV-1 are at increased risk for hospitalization, progression to acquired immunodeficiency syndrome, and death. Lenacapavir (LEN) is a first-in-class capsid inhibitor and has been evaluated through the CAPELLA phase 3 trial in PWH with replicative multidrug-resistant HIV-1. In this trial, LEN combined with an optimized background regimen (OBR) led to high levels of viral suppression, as more than 80% of participants achieved undetectable plasma HIV-RNA, associated with increasing in CD4 T cell counts. LEN has become publicly available in France from June 20, 2023, and prescriptions are discussed and validated by multidisciplinary committees in the hospitals, including HIV physicians, virologists and pharmacologists. From the time LEN was made publicly available in France, no real-world data have been generated to describe the real-world use of LEN, in association with an OBR, in various patient's profiles who may differ from the subjects included the CAPELLA trial. Thus, investigators plan to conduct a national, multicenter, retrospective observational study to describe baseline socio-demographic, clinical and biological profiles of PWH receiving LEN + OBR in French real-world settings, to determine the continuation of LEN injections at weeks 26 and 52, and to determine the reasons for stopping LEN in case of no continuation of LEN injections. In its current indication, LEN is reserved for a minority of PWH. However, France is the second-largest prescribing country for this drug, and one year after it was first marketed, it seems essential to review its use. Whether LEN injections are continued 6 and 12 months after starting treatment is a crucial question for understanding its use in treatment centers. Lenacapavir has become publicly available in France in June 20, 2023. LEN prescriptions in France are discussed and validated by multidisciplinary committees, including HIV physicians, virologists and pharmacologists in the hospitals.
