Study Details

Study Description

Brief Summary

There is a rapidly-growing need to identify evidence-based, safe, and effective co-treatment regimens for HIV-related tuberculosis (TB) among patients who require protease inhibitor (PI)-based antiretroviral therapy (ART). This study compared three alternative co-treatment options among participants in high TB endemic resource-constrained settings, in which one co-treatment option explores if an additional anti-HIV drug needs to be used when patients are being treated with a PI together with rifabutin-based anti-TB treatment.

Condition or Disease Intervention/Treatment Phase
Phase 2

Detailed Description

Rifampin (RIF), the cornerstone of TB treatment, has very problematic drug-drug interactions with PIs. The use of relatively high doses of ritonavir appear necessary to overcome this interaction, but it is unclear whether the co-treatment regimen of RIF-based TB treatment and double-dose PI-based ART will be safe and tolerable for patients with HIV-related TB and effective in treating both HIV and TB. The study proposed to determine if, for HIV-1-infected participants with active TB who require PI-based ART, a standard-dose lopinavir/ritonavir (LPV/r) regimen, with or without raltegravir (RAL), coupled with rifabutin (RBT)-based TB treatment is superior to a double-dose LPV/r regimen coupled with RIF-based TB treatment.

At study entry, participants were randomized (1:1:1) to receive standard-dose LPV/r-based HIV treatment plus RBT-based TB treatment (Arm A), double-dose LPV/r-based HIV treatment plus RIF-based TB treatment (Arm B), or standard-dose LPV/r-based HIV treatment plus RAL plus RBT-based TB treatment (Arm C).

Accrual was planned to take place in two accrual periods. Accrual period 1 would enroll 60 participants who would undergo an initial dose-finding period before continuing regular study follow-up. Once the review of the dose-finding pharmacokinetic (PK) and safety data from accrual period 1 participants was completed, accrual period 2 was planned to open to accrual.

Study duration was 72 weeks. Visits occurred at weeks 2, 4, 8, 12, 16, 20, 24, 32, 40, 48, and 72. The key evaluations included physical examination, clinical assessments, TB evaluations including chest x-ray, acid-fast bacilli (AFB) smear, mycobacterial culture, and drug susceptibility testing, CD4 cell count, HIV viral load, hematology, chemistry, and pregnancy testing in women of reproductive potential. Sputum, serum, and urine were stored for use in future analyses. An intensive PK visit occurred at day 12. PK blood draws in participants in Arms A and C were at RBT pre-dose and at 2, 4, 5, 6, and 24 hours RBT post-dose. PK blood draws in participants in Arm B were at LPV/r pre-dose and at 2, 4, 5, and 6 hours LPV/r post-dose.

The target sample size was 471 participants, but the study was terminated after 71 participants due to feasibility concerns. The 71 participants were followed for the planned 72 weeks. Because of the limited sample size, formal statistical comparisons were not undertaken as originally planned.

    Title Percent of Participants Whose HIV Viral Load Was Less Than 400 Copies/mL at Week 48.
    Description The percent of participants whose HIV viral load was less than 400 copies/mL at week 48 was calculated with an associated standard error. The confidence interval was calculated using Wilson's score method. Participants who were lost-to-follow-up or dead by week 48 or had missing results at week 48 were coded as having HIV viral load greater than 400 copies/mL. As stated in the Detailed Study Description of the Protocol Section, formal statistical comparisons were not undertaken because of limited sample size.

    Title Percent of Participants Who Experienced HIV Virologic Failure
    Description Virologic failure was defined as the occurrence of two consecutive plasma HIV-1 RNA levels ≥1000 copies/mL at or after 16 weeks and within 24 weeks of treatment initiation or ≥400 copies/mL at or after 24 weeks of treatment, regardless of whether randomized ART was being taken at the time of virologic failure. Participants who were missing data due to being lost-to-follow-up or dead were coded as virologic failures. The percent of participants who experienced HIV virologic failure was calculated with an associated standard error. The confidence interval was calculated using Wilson's score method. As stated in the Detailed Study Description of the Protocol Section, formal statistical comparisons were not undertaken because of limited sample size.

The percent of participants with HIV virologic failure at week 72 was calculated using a Kaplan-Meier estimator with an associated standard error.

    Title RAL AUC in Participants Enrolled in Arm C
    Description Describe RAL plasma PK characteristics (area under the curve [AUC] between 0 and 24 hours) in participants enrolled in Arm C, determined by non-compartmental analysis of 24-hour PK sampling. The pre-dose concentration was determined using a sample drawn 12 hours after the previous RAL dose and was used as the 12-hour RAL concentration.
    Time Frame At 2 weeks: pre-dose and at 2, 4, 5, 6, and 24 hours post-dose

    Outcome Measure Data

    Analysis Population Description
    Participants were included in this analysis if they completed the PK visit, did not miss any doses of any study-required medications on the day prior to the PK visit, and the RAL concentration at the pre-dose draw was above the assay's lower limit of quantification (5 ng/mL).

    Adverse Events

    Time Frame From study entry to either premature study discontinuation or study completion at Week 72.
    Adverse Event Reporting Description The study protocol required reporting of all new diagnoses; all new Grade 2 (moderate) or higher TB-related signs and symptoms, all new signs and symptoms Grade 3 (severe) or higher; all new all Grade 3 or higher laboratory values; and all signs, symptoms, and laboratory values that led to a change in treatment, regardless of grade. The DAIDS AE Grading Table (V1.0) and EAE Manual (V2.0) were used. All randomized participants who initiated study treatment were included.

    Limitations/Caveats

    The study was terminated after 71 of 471 participants enrolled. Therefore, the study was under-powered and formal statistical comparisons between study arms were not undertaken as originally planned. Instead, summaries within study arm were provided.
