Descriptive Information
Brief Title  ICMJE A Study to Evaluate the Effect of Cimetidine on CD4 Lymphocyte Counts in HIV Infection
Official Title  ICMJE A Study to Evaluate the Effect of Cimetidine on CD4 Lymphocyte Counts in HIV Infection
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.

Patients must have:

HIV positivity.

NOTE:

  • Patients on an antiviral or immunomodulating drug must have received it for at least 2 months and have no intention to make clinical or therapeutic changes in the first 8 weeks (such as adding a new agent or discontinuing effective viral suppressive therapy) that may interfere with the study.

NOTE:

  • Patients who become pregnant after enrollment will be permitted to continue on study drug but must sign an additional informed consent indicating their awareness of the issues in taking a drug with limited safety data during pregnancy.

Prior Medication:

Allowed:

  • Antiviral and immunomodulating drugs, provided patient has been on such therapy for at least 2 months prior to study entry.

Exclusion Criteria:

Co-existing Condition:

Patients with the following symptoms or conditions are excluded:

  • Known intolerance or hypersensitivity to cimetidine.
  • Evidence of active opportunistic infection or malignancy requiring high-dose systemic chemotherapy.
  • Any symptoms suggestive of concurrent illness that are not attributable to overall impairment by HIV or are not diagnosable based on the available evidence.
  • Inability to swallow tablets (gastric feeding tubes are allowed).
  • Not willing to comply with visit schedule and study procedures.

Concurrent Medication:

Excluded:
