A Pharmacologically Guided Phase I/II Study of Daily Orally Administered Synthetic Hypericin in HIV-Infected Subjects

To determine the safety and tolerance of daily oral hypericin when given to achieve target trough levels within defined cohorts. To determine the responses of surrogate markers of HIV infection to daily oral hypericin. It is not known whether daily oral dosing will produce a tolerable prolonged exposure to therapeutic levels of hypericin. Pharmacokinetic modeling studies have demonstrated that daily oral dosing should produce a trough level in a desired range without excessive peak levels.
