Titles & IDs
Public title
Clinical study to assess the efficacy and safety of a new antiretroviral drug (MPC-4326) in patients with Human immunodeficiency virus-1 (HIV-1) infection over a period of 14 days to 72 weeks.
Scientific title
title: A Phase II multicenter, open-label, randomized, parallel group, study of MPC-4326 in HIV-1 positive patients to evaluate the safety, efficacy, and pharmacokinetics of MPC-4326 administered as monotherapy for 14 days and as part of an optimized background regimen for up to 72 weeks.

Description of intervention(s) / exposure
MPC-4326 (code name) 200mg BID (twice daily) and 300mg BID doses of MPC-4326(tablets). Total duration of bevirimat treatment is 14 days minimum (monothereapy) to 72 weeks maximum (together with an optimised background regiment).

Outcomes
Primary outcome [1] 4214 0
Evaluate antiretroviral activity and safety administered as momotherapy for 14 days. Primary efficacy endpoint is defined as the mean change in viral load (HIV-1 Ribonucleic acid (RNA) log10 copies/mL0 from baseline at day 15).
Timepoint [1] 4214 0
At screening, baseline, day 1, 3, 7, 10 and 15.
Secondary outcome [1] 7130 0
Evaluate antiretroviral activity and safety for 72 weeks. Secondary efficacy endpoint is defined as the mean change in viral load (HIV-1 RNA (Ribonucleic acid) log10 copies/mL from baseline at weeks 4, 8, 16, 24, 32, 40, 48, 56, 64, 72, End of study visit)
Timepoint [1] 7130 0
At weeks 4, 8, 16, 24, 32, 40, 48, 56, 64, 72, End of study visit)
Secondary outcome [2] 7131 0
Explore the dependence of response on baseline HIV-1 Ribonucleic acid (RNA) levels, genotype and phenotype. Proportion of patients achieving 1.0 log10 reduction in viral load at weeks 4, 8, 16, 24, 32, 40, 48, 56, 64, 72, End of study visit. Proportion of patients with plasma HIV-1 RNA levels < 400 copies/ml at weeks 4, 8, 16, 24, 32, 40, 48, 56, 64, 72, End of study visit)
Timepoint [2] 7131 0
At weeks 4, 8, 16, 24, 32, 40, 48, 56, 64, 72, End of study visit)
Secondary outcome [3] 7132 0
To evaluate the emergence of mutations in HIV leading to resistance to MPC-4326 or other components of patient's treatment regimen. Measured as the proportion of patients with treatment-emergent resistant mutations in HIV RT (HIV Reverse Transcriptase), Protease, gp120 and CA-SP1 (Caspase1) at week 2; other timepoints will be analysed according to the profile of results observed.
Timepoint [3] 7132 0
At screening, baseline, Day1, 3, 7, 10 and 14.

Eligibility
Key inclusion criteria
- documented HIV-1-infection
- a CD4+-lymphocyte count =100 cells/mm3
- a screening plasma HIV-1 RNA value of 2,000 – 500,000 copies/mL.
- treatment-experienced patients must have documented evidence of genotypic resistance in their medical records (at screening) or have a resistance-associated primary mutation at screening by genotype to at least one approved ARV (Anti-retroviral) drug identified on the most recent IAS-USA l(international AIDS society USA) ist of resistance drug mutations
- For treatment-experienced patients: be receiving an antiretroviral therapy regimen containing at least 3 drugs which has been unchanged for at least 8 weeks prior to initial screening. Note: A washout period of at least 3 days prior to Day 1 of dosing is required.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients will be randomized to either 200 mg BID or 300 mg BID doses of MPC-4326. The randomization will occure central by phone via an interactive voice response system (IVRS), which needs to be called by the site staff for each patient.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Central stratification (IVRS) of the patients by prior antiretroviral use (treatment-experienced vs. treatment-naïve). Equal numbers of patients will be randomized to each treatment group within each stratum.
Masking / blinding
