ClinicalTrials.gov Identifier:
NCT00000748
First received: November 2, 1999
Last updated: September 28, 2013
Last verified: September 2013
  Purpose

To compare the safety and efficacy of two dosage regimens (daily and thrice-weekly) of sulfamethoxazole/trimethoprim (SMX/TMP; TMS) in the prevention of Pneumocystis carinii pneumonia (PCP) in high-risk HIV-infected patients.

Previous tests have shown that SMX/TMP given daily is effective in preventing recurrence of PCP and may be effective in preventing PCP in patients who have never developed it. Because SMX/TMP can cause side effects, this study will attempt to determine the safest and most effective dose of this combination.

Estimated Enrollment: 2500
Study Completion Date: November 1996
Detailed Description:

Previous tests have shown that SMX/TMP given daily is effective in preventing recurrence of PCP and may be effective in preventing PCP in patients who have never developed it. Because SMX/TMP can cause side effects, this study will attempt to determine the safest and most effective dose of this combination.

Patients receive SMX/TMP orally on a daily or thrice-weekly basis. Patients are clinically evaluated every 4 months. Patients on daily SMX/TMP who develop a drug-related toxicity may be switched to thrice-weekly SMX/TMP. Duration of follow-up is 12 months.
