Detailed Description:

Rationale: HIV infected persons have greater levels of inflammation and immune activation compared to the general population and are at greater risk of developing coronary heart disease (CHD) and other inflammation-associated co-morbidities. Intervention with BRM4 (Arabinoxylan Rice Bran Supplementation) in this population with impaired immune reconstitution may improve inflammation by a variety of mechanisms.

Intervention: Arabinoxylan Rice Bran Supplementation with BRM4, is a nutritional supplement marketed in the US. It is composed of dietary fiber obtained from a denatured hemicellulose that is obtained by reacting rice bran hemicellulose with multiple carbohydrate hydrolyzing enzymes from Shiitake mushrooms.

Objectives: The primary objective is to evaluate if 12 weeks of supplementation with arabinoxylan rice bran can safely reduce markers of inflammation during ART-suppressed HIV infection and thus potentially reduce the potential to develop end-organ disease in this group of at-risk patients.

Study population: HIV-infected participants (≥18 years of age) who have been on stable ART for at least 24 weeks prior to study entry, and have impaired immune reconstitution defined as a CD4+ T-cell count 100-350 cells/mm3 prior to study entry, with plasma HIV-1 RNA <50 copies/mL. In order to assure 24 evaluable subjects, the investigators will enroll 28 subjects total (assuming 15% lost to follow-up rate).

Study methodology: Randomized, double blind, placebo controlled clinical trial

Description of study arms: At entry participants will be randomized to one of the following arms:

Arm 1: BRM4 two 500mg capsules thrice daily p.o. for 12 weeks

Arm 2: Placebo for Biobran two capsules thrice daily p.o. for 12 weeks

Study endpoints: Primary - changes in sCD14 levels after 12 weeks of intervention. Secondary - week 12 changes in other inflammatory markers, microbial translocation, T-cell counts, and metabolic variables.

Follow-up: Participants will not be followed after study completion, unless follow-up is necessary for an adverse event.

Statistics: A total sample of 24 evaluable subjects (12 per arm) is needed to detect a clinically relevant difference of 0.07 log10 in sCD14 levels between treatment vs. placebo arms with 90% power and a 0.05 two-sided type I error rate.

Plans for analysis: For the primary analysis, changes in sCD14 (and other biomarkers) from baseline to week 12 will be compared between the treatment arm and the placebo arm by a two-sided, two-sample t-test.

  • If participating in sexual activity that could lead to pregnancy, the female study volunteer must be willing to use a contraceptive while receiving protocol-specified medication
  • Men and women age 18 years or greater.
  • Ability and willingness of participant or legal guardian/representative to provide informed consent.
  • Participants on statin therapy must be stable on the same dose for at least the prior 12 weeks with no anticipated change in statin or dose during the intervention

Exclusion Criteria:
