Evaluation of Kaletra Therapy Over the Long-term

Completed
Conditions
Human Immunodeficiency Virus
Interventions
Drug: Lopinavir/Ritonavir (Kaletra)
Registration Number
NCT01083810
Lead Sponsor
Abbott
Brief Summary

Long term observation of patients under lopinavir/ritonavir containing therapy

Detailed Description

Three to five year observation of lopinavir/ritonavir therapy. Reporting groups are 1) therapy-naïve patients (144 weeks), 2) therapy-experienced but protease inhibitor naïve patients (240 weeks,) and 3) non-B subtype infected patients (240 weeks).

These three groups of participants with HIV-1 infection were at first registered as three different studies: KAL1RO (this study, NCT01083810, n=137), KAL2RO /KAL5RO (NCT01083836, n=92), and KAL6RO (NCT01081470, n=55) but were now reconciled under KAL1RO (NCT01083810) as a single study with three reporting groups.

Primary Outcome Measures
NameTimeMethod
Number of Patients With Virus That Develop Mutations Conferring Resistance to Lopinavir/Ritonavir, NRTIs or NNRTIsBaseline and at any timepoint where testing is possible

Standard genotypic resistance assays were developed for HIV-1 viral load levels greater than 500 to 1000 copies per milliliter (mL). All 3 protocols recommended this testing be done at Baseline prior to lopinavir/ritonavir therapy and (if possible) in cases of virologic failure. The exact timing varied and depended on whether there was an adequate viral load and physician clinical judgment. Participants with resistance to lopinavir/ritonavir, nucleoside reverse transcriptase inhibitors (NRTI) or non-nucleoside reverse transcriptase inhibitors (NNRTI) at Baseline and follow-up are reported.

Secondary Outcome Measures
NameTimeMethod
Percentage of Patients With HIV-1 RNA <50 Copies/mlBaseline, Week 4, 12, 24, followed by 12-week intervals up to 144/240 weeks

All 3 protocols recommended that HIV viral load tests be performed at Baseline and each study visit. Study visits were to occur at approximately Weeks 4, 12, and 24, followed by 12-week intervals up to Week 144 in therapy-naive participants and up to Week 240 in the pre-treated and non-B subtype groups. The percentage of participants with HIV-1 ribonucleic acid (RNA) less than 50 copies/mL at each time point is presented by subgroup.

Percentage of Patients With HIV-1 RNA 50 to <200 Copies/mlBaseline, Week 4, 12, 24, followed by 12-week intervals up to 144/240 weeks

All 3 protocols recommended that HIV viral load tests be performed at Baseline and each study visit. Study visits were to occur at approximately Weeks 4, 12, and 24, followed by 12-week intervals up to Week 144 in therapy-naive participants and up to Week 240 in the pre-treated and non-B subtype groups. The percentage of participants with HIV-1 RNA levels of 50 to less than 200 copies/mL at each time point is presented by subgroup.

Percentage of Patients With HIV-1 RNA 200 to <500 Copies/mlBaseline, Week 4, 12, 24, followed by 12-week intervals up to 144/240 weeks

All 3 protocols recommended that HIV viral load tests be performed at Baseline and each study visit. Study visits were to occur at approximately Weeks 4, 12, and 24, followed by 12-week intervals up to Week 144 in therapy-naive participants and up to Week 240 in the pre-treated and non-B subtype groups. The percentage of participants with HIV-1 RNA levels of 200 to less than 500 copies/mL at each time point is presented by subgroup.

Percentage of Patients With HIV-1 RNA >500 Copies/mlBaseline, Week 4, 12, 24, followed by 12-week intervals up to 144/240 weeks

All 3 protocols recommended that HIV viral load tests be performed at Baseline and each study visit. Study visits were to occur at approximately Weeks 4, 12, and 24, followed by 12-week intervals up to Week 144 in therapy-naive participants and up to Week 240 in the pre-treated and non-B subtype groups. The percentage of participants with more than 500 HIV-1 RNA copies/mL at each time point is presented by subgroup.

Change in Absolute CD4 Cell Count [CD4+ Cells/µL]Baseline, Week 4, 12, 24, followed by 12-week intervals up to 144/240 weeks

The evolution of participants' CD4-positive (CD4+) T-lymphocyte counts after starting the lopinavir/ritonavir-containing regimen was to be assessed by measuring the number of CD4+ cells at baseline and each subsequent study visit. Study visits were to occur at approximately Weeks 4, 12, 24, followed by 12-week intervals up to Week 144 in therapy-naive participants and up to Week 240 in the pre-treated and non-B subtype groups. CD4+ cell count results are reported as the change from Baseline in the absolute number of CD4+ cells per microliter.
