Trial Information

A Phase I/II Dose Ranging Trial of Oral Dextran Sulfate (UA001) in HIV Infected Individuals and in Patients With Acquired Immunodeficiency Syndrome (AIDS) or AIDS Related Complex (ARC)

Although zidovudine (AZT) has shown promise in prolonging life in patients with AIDS and
severe ARC, it has significant blood toxicities. It would be beneficial to combine AZT with
another antiviral agent that does not have the same toxicity. DS might be a suitable drug
since it has shown antiviral activity against HIV in the laboratory, and in preliminary
studies it has shown little toxicity. Also, the combination of DS with AZT has been shown to
be more effective than either alone.

The study will begin with 10 patients with AIDS, 10 with ARC, and 10 with asymptomatic HIV
infection taking DS by mouth 3 times a day for 24 weeks. If the initial dose of DS is
tolerated without significant side effects, the next group of patients will receive a higher
dose. A third group of patients will be given either a higher or lower dose depending on the
results of the earlier groups. Patients will be evaluated every other week for 12 weeks,
then monthly for the remaining 16 weeks. Patients will have the option of continuing DS
until the entire study is completed if the drug is well tolerated. Inhaled pentamidine for
the prevention of Pneumocystis carinii pneumonia is allowed, but other investigational drugs
are not. Drug effects on the HIV virus, immune function, and clinical condition will be
monitored during the periodic evaluations.
