"OK 2004 Study" (Only Kaletra 2004 Study): Study to Evaluate Suspending Nucleosides From Triple-Drug Therapy in HIV Subjects
Phase III-IV, Comparative, Randomized, Open-Label, Study to Evaluate Safety and Efficacy of Suspending Nucleosides From a Triple-Drug Therapy Based on Lopinavir/Ritonavir Versus Continuing Triple-Drug Therapy in HIV-Infected Subjects With Undetectable Plasma HIV Viremia for Six Months
연구 개요
상세 설명
Primary Study Objective: Efficacy and durability of switching to lopinavir/ritonavir single-drug HAART compared to maintaining therapy based on lopinavir/ritonavir and two nucleosides
Secondary Study Objective(s):
- Safety (related drug AEs/SAEs and laboratory anomalies G3/4) through 48 w.
- Resistance profile on patients with sustained virological failure
- QOL comparing stopping nucleosides versus continuing therapy
- Pharmaco-economic analysis comparing treatment cost between the 2 study arms.
- Predicting factors of failure in the stopping nucleosides arm
Subject Population: 200 patients
Study Design:
RANDOMIZATION:
Patients are randomized (1:1) either to continue under the same treatment or stop nucleosides as follows:
- Stopping nucleosides arm: Lopinavir/r alone.
- Continuing arm: Lopinavir/r + 2 NRTIs
STUDY PROCEDURES: A baseline HIV-RNA, CD4 and routine labs will be collected if the most recent results are not collected within the 4 weeks prior entering the study. Patients will be followed for HIV-RNA (and CD4) at w1, w4, w8, w16, w24, w 36 and w48. After w48, durability of response to lopinavir/r single-drug therapy will be studied long-term (up to w96). Routine hematology and clinical chemistry (including fasting triglycerides and cholesterol, total and HDL/LDL ratio) will be measured at w4, w16, w24, w 36 and w48. A central laboratory will be used for HIV-RNA determinations and to archive plasma/cell samples for further genotype test in case of rebound.
Treatment adherence will be followed with a self-patient report questionnaire (GEEMA study)
All AEs will be collected if suspected relation (possible or probable) to any concomitant ARV drug, and SAEs, related or not, reported within 24h.
