About this study

The study consisted of four steps. Study duration was up to 240 weeks.

At the study Step 1 entry, participants were randomized with equal probability to each of the three regimens (ET+ART, BV+ART, PTX+ART). The original target sample size was 706. Randomization was stratified by:

  • Screening CD4 lymphocyte cell count (<100, >=100 cells/mm³), and
  • Country.

For participants who had an initial Independent Endpoint Review Committee (IERC) confirmed KS response and subsequent IERC-confirmed KS progression, and who, in the opinion of the investigator and with concurrence of the protocol Clinical Management Committee (CMC), could potentially have benefitted from another course of the same chemotherapy utilized in Step 1, entered Step 2. (Please see details on Step 2 eligibility.)

In Step 3, participants were randomized with equal probability to one of the two chemotherapy arms not utilized in Step 1. (Please see details on Step 3 eligibility.)

In Step 4, participants were assigned to the remaining study-provided chemotherapy not given in Step 1, Step 2 or Step 3. (Please see details on Step 4 eligibility.)

Step 1 visits occurred at screening, entry and weeks 3, 6, 9, 12, 15, 18, 21,24, 27, 30, 33, 36, 39, 42, 45, 48, 60, 72, 84 and 96 from study entry. Visits for Steps 2, 3 and 4 were scheduled at entry and weeks 3, 6, 9, 12, 15, 18, 21,24, 27, 30, 33, 36, 39, 42, 45, 48, 60, 72, 84 and 96 from the corresponding step entry date. Key evaluations included targeted physical examination, clinical assessment, KS examination, hematology, chemistry, pregnancy testing (for women of reproductive potential), and pulse oximetry for participants on BV+ART. CD4 count and HIV viral load were obtained every 12 weeks. Assessment of peripheral neuropathy was done at screening, weeks 9 and 21, and for those on BV+ART or PTX+ART, additionally at weeks 3, 6, 15 and 18. KS tumor punch biopsy, serum, plasma and peripheral blood mononuclear cells (PBMCs) were obtained and stored for use in future analyses. Participants also completed ET and ART adherence evaluations and quality of life questionnaires.

Enrollment to ET+ART and initiation of ET+ART in subsequent steps were discontinued in March 2016, based on the recommendation of the Data and Safety Monitoring Board (DSMB) due to ET+ART being less effective than PTX+ART. No safety concerns were identified. ET+ART participants in Step 1 or Step 2, in discussion with the local investigator and in consultation with the protocol CMC, could discontinue ET and enter Step 3. ET+ART participants in Step 3 could discontinue ET and start the remaining chemotherapy regimen in Step 4 in discussion with the local investigator and in consultation with the protocol CMC. Unless otherwise indicated, comparison between ET+ART and PTX+ART was based on the March 2016 data. The study remained open to enrollment and the remaining participants were randomized at Step 1 entry between BV+ART and PTX+ART. The target total sample size was revised to 446.

The DSMB recommended stopping the study in March 2018 due to BV+ART being inferior to PTX+ART. No safety concerns were identified. Study accrual was stopped. Eligible Step 1 PTX+ART participants entered Step 2 to receive PTX+ART; Step 1 and Step 2 BV+ART participants eligible to receive PTX+ART moved to Step 3 to receive PTX+ART. Otherwise, participants permanently transitioned to local care upon arrangement of appropriate oncology and ART, and then went off study. Participants who received ET while on study were followed for 144 weeks after beginning the last cycle of ET.

Comparison between BV+ART and PTX+ART was based on the March 2018 data.

Treatment and study plan

Etoposide (ET)

Drug

Beginning on day one of the chemotherapy cycle, ET was given orally in a dose of 50 mg twice daily for 7 consecutive days for the first cycle. If there was no Grade >= 2 toxicity attributable to ET after the first cycle, the dose was escalated to 150 mg daily for 7 days in divided doses of 100 mg/50 mg for the second cycle. After the second cycle, if there was no Grade >= 2 toxicity attributable to ET, the dose was escalated to 100 mg twice daily for 7 days for the third and subsequent cycles.

Treatment with ET was continued for six cycles at the maximum dose achieved or until toxicity requiring discontinuation of study chemotherapy, or the site investigator, after consulting with the protocol CMC, had determined that alternative therapy is required, whichever occurs first.

Bleomycin and Vincristine (BV)

Drug

BV was administered on day one of each chemotherapy cycle.

Vincristine sulfate was administered at a dose of 2 mg (fixed dose) in a volume of 2 mL over 1 minute into the sidearm of a rapidly flowing intravenous infusion every 3 weeks. The vincristine infusion was followed by bleomycin as detailed below.

Bleomycin sulfate was administered at a dose of 15 units/m^2 over 10 minutes every 3 weeks.

Treatment with BV was continued for six cycles, or until toxicity requiring discontinuation of study chemotherapy, or the site investigator, after consulting with the protocol CMC, had determined that alternative therapy is required, whichever occurs first.

Paclitaxel (PTX)

Drug

Paclitaxel was administered by IV infusion in 200 mL, 250 mL, or 500 mL of 5% dextrose or 0.9%Sodium Chloride for injection at a dose of 100 mg/m^2 body surface area (BSA) every 3 weeks.

Co-formulated Efavirenz/Emtricitabine/Tenofovir Disoproxil Fumarate (EFV/FTC/TDF)

    IERC-confirmed KS progression refers to KS disease progression confirmed by the IERC based on comparing follow-up KS response to study entry or best KS response with respect to clinical assessment of KS cutaneous lesions (count, character and marker lesion area), oral KS, visceral KS and tumor-associated edema and as described in the publications (Krown et al 1989, Cianfrocca et al 2002). AIDS-defining events refer to non-KS AIDS-defining diagnosis (WHO Stage 4 (2007), plus microsporidiosis, cyclospora gastroenteritis, Chagas disease and visceral leishmaniasis). Virologic failure is defined as two successive measurements of plasma HIV-1 RNA >=1000 copies/mL at week 12 to week 24 or RNA >=400 copies/mL at week 24 or later. Objective response refers to complete response or partial response as best overall KS response. Results are presented by Step 2 treatment arm.
