Study to Evaluate Safety and Toxicity of Polyphenon E (EGCG) in HIV-1-Infected Individuals

Completed · Phase 1 · Has a placebo group

Conditions studied: HIV Infection

In brief

The purpose of this study is to determine the safety, toxicity, dosing, and antiviral effects of epigallocatechin gallate (EGCG) in capsule form (Polyphenon® E), administered orally twice daily at three different doses in HIV-1-infected clinically stable, treatment-naïve and treatment-experienced adults not on concomitant antiretroviral (ARV) therapy.
