Efficacy of Doravirine + Dolutegravir Dual Therapy in the Context of Antiretroviral Therapy Switch

• Status: Not yet recruiting
• Trial end date: 2025-02-01
• Target enrollment: 0
• Participant gender: All

Summary

Combination antiretroviral therapy (cART) HIV treatments are associated with increased quality of life, and a normalisation of life expectancy in people living with HIV. However, long-term use of cART can lead to side-effects through exposure to drug-related toxicity.

For this reason researchers are interested in looking at alternative therapies that might expose patients to fewer and less severe side effects while providing the same quality of care as antiretroviral therapies most often used to treat HIV.

The purpose of this study is to investigate if the study drug combination that is being tested (doravirine + dolutegravir) is safe compared with other triple cART regimens.

• Phase: Phase 3
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Chelsea and Westminster NHS Foundation Trust
• Treatments: Dolutegravir

Criteria

Inclusion Criteria:

• HIV-1 infected, 18 years or older

• On stable & suppressive triple cART for at least 6 months

• No evidence of resistance to DOR or DTG

• No laboratory abnormalities, medical/psychiatric conditions or alcohol/drug use considered a barrier to participation by investigators

• Women who are pre-menopausal and sexually active should be on one of the following methods of contraception:

• Implant

• Depot injection

• Intra-uterine device or system

• Oral hormonal contraception

Exclusion Criteria:

• History of virological failure on an NNRTI in absence of a post-failure genotypic resistance test proving absence of resistance to DOR

• History of virological failure on an INSTI in absence of a post-failure genotypic resistance test proving absence of resistance to DTG (INSTI mutations that will lead to the need of administering DTG twice-daily are considered as resistance to DTG - and the subject will be considered NOT eligible)

• Concomitant medication contra-indicated with DTG or DOR

• Haemoglobin <9 g/dL

• Platelets <80,000/mm3

• Creatinine clearance <30 mL/min

• AST or ALT ≥5N

• Acute Hepatitis A infection.

• Concomitant DAA for anti-HCV therapy

• Known acute or chronic viral hepatitis B or C.

• Individuals testing positive for HBcAb, but negative HBsAg/HBeAg, may be included on the trial.

• Individuals with positive anti-HCV results, but with HCV RNA not detected may be included on the trial.

• Pregnant or breastfeeding women
