- Conditions
- HIV Infections
- Registration Number
- NCT00002092
- Lead Sponsor
- Community Research Initiative of New England
- Brief Summary
To determine the change in CD4 count after 4 and 8 weeks in HIV-infected patients treated with cimetidine compared to placebo. To observe time-associated trends at weeks 4, 8, 12, and 16 in the change of CD4 counts for patients taking cimetidine for the full 16 weeks. To establish a safety record for cimetidine use in HIV-positive patients.
