A Phase I Dose Escalation Study of Synthetic Hypericin in HIV-Infected Patients With Less Than 300 CD4 Lymphocytes

To determine the maximum tolerated dose (MTD) of hypericin, to define the types of toxicities that may be observed, and to determine what doses of the drug are associated with improvements in virological and immunological surrogate markers of HIV infection. To determine the bioavailability of synthetic hypericin given in 2 percent benzyl alcohol solution. Hypericin is unlike other drugs presently being used to treat AIDS patients. Hypericin shows anti-HIV activity in test tube experiments.
