Clinical Trials
1 A Randomized, Blinded, 12-week Comparison of Elvucitabine/Efavirenz/Tenofovir Versus Lamivudine/Efavirenz/Tenofovir in HIV-1 Infected, Treatment Naive Subjects. There is a 36 Week, Open Label, Extension Phase for Eligible Subjects.
Elvucitabine is a novel nucleoside analog that is being studied as a treatment for patients infected with HIV-1. This Phase II study will enroll 60 HIV-1 naive subjects to assess the efficacy and safety of elvucitabine compared to lamivudine in combination with tenofovir and efavirenz measured by changes in the patient's HIV-RNA level and CD4 cell count. The study treatment will be 12 weeks of blinded study medication followed by an additional 84 weeks of open label treatment if the patient's response to treatment meets certain endpoints. Also there will be assessment of the pharmacokinetics of elvucitabine during the study.

This is a double-blind Phase 2a study to test the safety and efficacy of an investigational HIV drug, amdoxovir (300 mg or 500 mg twice daily) compared with tenofovir DF 300 mg once daily in HIV-1 infected antiretroviral therapy-experienced subjects who are currently failing antiretroviral therapy. There are three treatment groups (N=45). Subjects will be randomized to receive either amdoxovir 300 mg twice daily (n=15) or amdoxovir 500 mg twice daily (n=15) or tenofovir DF 300 mg once daily (n=15); each in combination with zidovudine 300 mg twice daily. The study will assess initially amdoxovir (300 mg or 500 mg twice daily) or tenofovir DF 300 mg once daily, both in combination zidovudine 300 mg twice daily plus failing third drug, but then with lopinavir/ritonavir (400 mg/100 mg twice daily) after Week 2. Subjects who received amdoxovir (300 mg or 500 mg twice daily) and benefited from the drug may choose to enroll in the 36-week open-label study.

Weight gain following antiretroviral therapy (ART) initiation occurs with all modern regimens. Recent real-world reports suggest that integrase strand transfer inhibitor (INSTI)-based ART may be associated with excess weight gain compared to other regimens. Weight gain appears to occur regardless of baseline weight, and is most pronounced among women and minorities, often those at highest risk of obesity-associated comorbidities. INSTI- and TAF-based regimens are now preferred regimens for most persons according to the Department of Health and Human Services ART-Treatment Guidelines. As a result, there is an urgent need to understand the underlying mechanisms for this weight gain. This study aims to understand the changes in energy balance that occur with changes in ART. Participants with HIV who have experienced >10% weight gain on INSTI (bictegravir or dolutegravir-based therapy) will be switched to doravirine for 12 weeks, and then back to their prior INSTI regimen, allowing for assessment of changes in metabolic parameters with drug withdrawal and reintroduction (with no change to NRTI-backbone). Twenty-four hour energy balance will be measured on both regimens during a 24-hour stay using a whole room indirect calorimetry, with a standardized diet. Ultimately, the investigator's goal is to understand the mechanisms of weight gain so that future interventions can most effectively mitigate ART-associated weight changes.
