Description

There is no proven therapy for cryptosporidiosis in persons with AIDS. Nitazoxanide appears to be a good candidate drug for further evaluation because of its effectiveness in preclinical models, the data from early clinical trials and its safety profile. Cooperation between clinical researchers and basic scientists in clinical trials of agents for HIV infection and its complications is a high priority for the ACTG, the NIAID, and the NIH. Thus, it is important to design a clinical trial of NTZ that includes cooperation with basic scientists. Patients will be randomized to the active drug o...

  • NOTE:
  • Patients who have been treated for MAC disease for at least 4 weeks and have resolved their symptoms may be enrolled. Patients dually infected with microsporidiosis may be randomized to the study but will not count toward the sample size.

  • Excluded:
  • Need for continuing use of any medications with putative anticryptosporidial activity, including paromomycin, azithromycin, clarithromycin, spiramycin, bovine colostrum, monoclonal anticryptosporidial antibody preparations, letrazuril, atovaquone, diclazuril, octreotide and albendazole (prohibited during the acute treatment phase for patients dually infected with microsporidiosis)..
  • NOTE:
  • Patients who develop cryptosporidiosis while taking azithromycin or clarithromycin may be enrolled as long as they have been taking those medications for at least four weeks and remain on a stable dosage.
  • All antidiarrheals that are not part of the protocol directed Antidiarrheal Stabilization Regimen.
  • The addition of any new antiretroviral agent or immunomodulator therapy the first 63 days on the study.
  • Prior Medication:
