Primary outcome:	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:	At screening, baseline, day 1, 3, 7, 10 and 15.
Secondary outcome 1:	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:	At weeks 4, 8, 16, 24, 32, 40, 48, 56, 64, 72, End of study visit)
Secondary outcome 2:	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:	At weeks 4, 8, 16, 24, 32, 40, 48, 56, 64, 72, End of study visit)
Secondary outcome 3:	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:	At screening, baseline, Day1, 3, 7, 10 and 14.

Study type:

Interventional

Purpose of the study:

Treatment

Allocation to intervention:

Randomised controlled trial

Describe the 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.

Describe the 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.

Brief summary:

The main purpose of this research study is to evaluate the antiretroviral (how effective the drug is at reducing the amount of HIV in the blood) activity of two different doses of MPC-4326 in HIV-1 positive participants and what, if any, side effects there may be through 14 days of dosing. This study will also evaluate the antiretroviral activity and safety of bevirimat in participants who continue treatment with bevirimat as part of combination highly active antiretroviral therapy for up to 72 weeks. We also want to know how much of the drug gets into your blood stream following oral administration. We are asking participants who will start their treatment for the first time (so called naïve (exposed to treatment for the first time) participants) and who are already on treatment (treatment experienced participants) to participate. If you choose to participate in this study and do not intend to continue MPC-4326 treatment past 14 days, you should not expect any medical benefits from taking part in this study and it is even possible that your HIV could worsen during the study. The potential benefit to society may be information gained on the safety and effectiveness of the study treatment for patients in the future. However, if you choose to participate in this study and intend to continue MPC-4326 treatment past 14 days should your viral load reduction in those first 14 days be at least two-thirds or 66.6% as compared with your viral load value at baseline, then you may have medical benefits from taking part in this study. These possible benefits include a persistent viral load reduction and an improvement in the CD4 count (a blood marker of immune system health) that may occur. As this is an experimental medication, the likelihood of these benefits occurring for you is not yet known.
