HIV Clinical Trial

Official title:
Booster-free Antiretroviral Therapy for Persons Living With HIV and Multidrug Resistance: A Multicentre Multi-stage Randomized Trial

Clinical Trial Summary

The primary objective of the study is to evaluate the efficacy of a booster-free regimen including DOR/DTG/3TC among HIV-suppressed PLWH with previous virological failure. The key secondary objectives are i) to determine whether switching to DOR / DTG / 3TC leads to lower burden of DDI compared to continuing a booster-containing regimen, and ii) to assess changes in patient perception on treatment acceptability and satisfaction, as well as health-related quality of life after a switch to booster-free ART. Qualitative sub-study: Qualitative objectives will be met using semi-structured interviews. Thirty people (15 from the intervention arm, 15 from the control arm) will be interviewed twice, at week 0 and week 48. Additional 15 individuals from the observational cohort will be interviewed once. Interviews will take place following study visits and performed using semi-structured guides. The guide for the interviews at week 48 will be based on results from analyses of the interviews conducted at week 0.

Clinical Trial Description

Life expectancy of persons living with HIV on antiretroviral therapy (ART) is increasing and drug-drug interactions (DDI) with co-medications are becoming a major concern. Individuals who previously experienced virological failure are at risk of DDI as they are generally treated with ritonavir- or cobicistat-boosted ART. The high potency as well as the favorable safety and pharmacokinetic profile of new antiretroviral drugs, including dolutegravir (DTG) and doravirine (DOR), support their evaluation as part of un-boosted therapy for individuals with a history of virological failure. In this adaptive trial within the Swiss HIV Cohort Study (SHCS) and partner clinics in the Netherlands, the investigators aim to evaluate the efficacy and acceptability of the booster-free regimen DOR/DTG/3TC for treatment-experienced individuals. ;
