Results Presented at the International AIDS Conference Showed Benefits of Serum-Derived Bovine Immunoglobulin (SBI), the main ingredient in EnteraGam®, in Patients with HIV-Associated Enteropathy

Entera Health, Inc. today announced results from a multi-center study evaluating the impact of SBI in patients with HIV-associated enteropathy. An improvement was observed in circulating levels of CD4+ T-cells following 4 weeks of SBI therapy in patients who started the trial with the lowest numbers of CD4+ cells (≤418 cells/microliter) compared to a placebo group (p=0.02). This effect was maintained through 24 weeks of SBI therapy. Evidence for restoration of mucosal immunity (increase in duodenal CD4+ T-cells, p=0.02) was also observed in a subset of patients who received SBI therapy for 24 weeks and underwent upper endoscopy and duodenal biopsy.

“Collectively, these results suggest that SBI therapy may be a novel strategy to restore mucosal immunity and impact systemic reconstitution among patients who have not achieved normal CD4+ T-cell counts despite prolonged HAART”, said Dr. David Asmuth, Professor of Medicine at the University of California at Davis who presented the findings at the 8th International AIDS Conference on HIV Pathogenesis, Treatment and Prevention in Vancouver, Canada.

The study enrolled HIV-infected patients who were on long-term highly active antiretroviral therapy (HAART) with documented HIV-associated enteropathy. Study subjects received SBI at a dose of 2.5 vs 5.0 grams or placebo twice daily during a 4-week, placebo-controlled phase that was followed by a placebo-free extension phase where subjects took SBI at 2.5 vs 5.0 grams for an additional 20 weeks. Study parameters included GI symptoms, biomarkers of peripheral and mucosal immunity, gut microbiome and evaluation of intestinal function.
