HIV-1 Infection Clinical Trial
Official title:
Safety, Tolerability, and Effects of the Probiotic Visbiome Extra Strength on Gut Microbiome and Immune Activation Markers in HIV-Infected Participants on Suppressive Antiretroviral Therapy: A Phase II Study
The purpose of the study was to evaluate whether the probiotic Visbiome Extra Strength reduces inflammation in HIV-infected men and women when compared to a placebo (inactive medication like a dummy pill). The study evaluated whether taking Visbiome Extra Strength by mouth for 24 weeks was safe and well-tolerated for HIV-infected persons on antiretroviral therapy (ART). Probiotics are germs such as yeast or bacteria that are found in food and supplements that are used to improve the health of the digestive system. Many people refer to probiotics as "helpful bacteria." These bacteria live in the body and help the body work normally. In some medical conditions, including HIV infection, helpful bacteria are replaced with bacteria that can change the normal intestinal function and increase inflammation. The investigators tested whether giving a probiotic restored normal intestinal function and decreased inflammation.
This was a phase II, randomized, double-blind, two-arm study to evaluate whether there is a
significant change in sCD14 after 24 weeks of probiotic Visbiome Extra Strength (ES) therapy,
and to determine the safety and tolerability of this agent in HIV-infected participants on
stable antiretroviral therapy (ART). Participants were randomized 1:1 to Visbiome ES and
placebo arms. Both arms initiated study treatment at Week 2 and took 1 sachet per day for the
first 2 weeks and then 1 sachet twice daily for the next 22 weeks. All participants were
followed for an additional 12 weeks off study product.
The study clinic visits included Entry (Week 0), and Weeks 2, 6, 14, 25, 26, and 38. Plasma
for the primary outcome was collected at Weeks 0, 2, 25, and 26. The evaluations of safety
(clinical assessment for signs and symptoms, diagnoses, and laboratory tests) were done at
Weeks 2, 6, 14, 26, and 38.
Currently, the results are entered for the primary outcome measure and select secondary
outcomes only. The results on the remaining secondary outcomes will be posted when they
become available.
