NCT00752856
CCTG 589 is a randomized, open-label, pilot study comparing the efficacy, safety and tolerability of RAL plus LPV/r to EFV plus TDF/FTC in HIV-infected, treatment-naïve subjects. Subjects will be ineligible if they have any evidence of drug resistant virus in the past or at the time of screening (if never previously tested). Those who are found to be eligible will be randomized 1:1 to initiate either LPV/r (400/100 mg) plus RAL (400mg), both given twice-daily, or fixed dose combination of EFV (600 mg), TDF (300 mg) and FTC (200 mg) given as once-daily Atripla® for 48 weeks. Hypotheses 1. The novel nucleoside-sparing combination of LPV/r + RAL will have a faster phase 1 viral decay rate compared to standard-of-care therapy with EFV/TDF/FTC in antiretroviral-naïve patients. 1. Faster phase 1 viral decay dynamics will be associated with improved longer-term (week 48) viral suppression. 2. Faster phase 1 viral decay dynamics will be associated with accelerated early (Day 0-14) clearance of cell-associated HIV DNA. 3. Faster phase 1 viral decay dynamics will be associated with greater early (baseline to week 12) CD4+ T-cell recovery. 2. The LPV/r + RAL arm will have greater decreases in early (baseline to week 4) CD4/CD8 T-cell immune activation and apoptosis which will be associated with greater late (week 12 to week 48) CD4+ T-cell recovery. 3. Subjects treated with LPV/r + RAL arm will have smaller changes in total cholesterol and triglycerides from baseline than those receiving EFV/TDF/FTC.
NCT03821948
The primary objective of this study is to collect de-identified, clinically-characterized stool and whole blood specimens for use in developing and evaluating the performance of new biomarker assays for detection of colorectal cancer (CRC).
