Safety and Effectiveness of Nitazoxanide for the Treatment of Cryptosporidiosis in AIDS Patients

Phase 3TerminatedNCT00004986

Romark Laboratories L.C.30 enrolled

Overview

The purpose of this study is to see if it is safe and effective to treat cryptosporidiosis in AIDS patients with nitazoxanide.

Patients take nitazoxanide daily for 8 weeks with a dose escalation after the first 4 weeks. Patients return to the hospital for examinations every 2 weeks during the 8-week treatment period and 6-week follow-up. Nitazoxanide therapy is discontinued in patients showing a complete clinical and parasitologic response (therapeutic cure) after 8 weeks of treatment and in patients showing a therapeutic cure at two consecutive visits (Weeks 2 and 4 or Weeks 4 and 6). These patients undergo a physical examination including stool analysis for Cryptosporidium parvum oocysts and routine laboratory tests at Weeks 2, 4, and 6 after completion of nitazoxanide therapy. Patients who do not show a complete clinical and parasitologic response (therapeutic failure) after 8 weeks of treatment are allowed to remain on nitazoxanide therapy through the Open Label Compassionate Use of Nitazoxanide in Treatment of Cryptosporidiosis in AIDS Patients (UMD-95-009) protocol.
