Clinical Trials Search.org is a site committed to listing clinical research studies in human subjects. An Open-Label, Multicenter Study to Evaluate the Safety and Tolerability of Dideoxycytidine (ddC) in Patients With AIDS or Advanced ARC Who Previously Demonstrated Intolerance to Zidovudine (AZT) in Protocol N3300 or N3492 Clinical research trials and An Open-Label, Multicenter Study to Evaluate the Safety and Tolerability of Dideoxycytidine (ddC) in Patients With AIDS or Advanced ARC Who Previously Demonstrated Intolerance to Zidovudine (AZT) in Protocol N3300 or N3492 health trials occur in hundreds of cities throughout the U.S.A.. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials typically assess the effectivity of new drugs. The propose of the studies / undertakings is to resolve certain human health questions. Clinical trials are a popular means for physicians, government agencies, and private sector companies to locate treatments for all sorts of conditions, including An Open-Label, Multicenter Study to Evaluate the Safety and Tolerability of Dideoxycytidine (ddC) in Patients With AIDS or Advanced ARC Who Previously Demonstrated Intolerance to Zidovudine (AZT) in Protocol N3300 or N3492. An Open-Label, Multicenter Study to Evaluate the Safety and Tolerability of Dideoxycytidine (ddC) in Patients With AIDS or Advanced ARC Who Previously Demonstrated Intolerance to Zidovudine (AZT) in Protocol N3300 or N3492 Clinical Trials and other clinical trials permit volunteers to acquire medical treatment choices before they are available to the masses. Some times the test subjects obtain professional assistance for free, and every now and again they are compensated for their time. Sometimes there is a cost for a An Open-Label, Multicenter Study to Evaluate the Safety and Tolerability of Dideoxycytidine (ddC) in Patients With AIDS or Advanced ARC Who Previously Demonstrated Intolerance to Zidovudine (AZT) in Protocol N3300 or N3492 clinical trial. Participants oftentimes recieve the most expert healthcare available for their An Open-Label, Multicenter Study to Evaluate the Safety and Tolerability of Dideoxycytidine (ddC) in Patients With AIDS or Advanced ARC Who Previously Demonstrated Intolerance to Zidovudine (AZT) in Protocol N3300 or N3492 condition. Hazards are a reality, however, and can include extra or frequent physician visits, health risks (potentially life-endangering), and/or the treatment being uneffective. Trials are federally governed with rigorous guidelines to protect clinical trials subjects.

An Open-Label, Multicenter Study to Evaluate the Safety and Tolerability of Dideoxycytidine (ddC) in Patients With AIDS or Advanced ARC Who Previously Demonstrated Intolerance to Zidovudine (AZT) in Protocol N3300 or N3492
For Condition: HIV Infections
Status: Completed
Sponsor(s): Hoffmann-La Roche ,
Synopsis: To demonstrate that zalcitabine (dideoxycytidine; ddC) monotherapy is safe and tolerable in the treatment of patients with AIDS or advanced AIDS related complex (ARC) who previously demonstrated intolerance to zidovudine (AZT) treatment while in Protocol N3300 (NIAID ACTG 114) or N3492 (NIAID ACTG 119). NOTE OF CAUTION FOR CONCOMITANT MEDICATIONS ON STUDY: Patients on amphotericin, pyrimethamine, sulfadiazine, trimethoprim/sulfamethoxazole, ganciclovir, intravenous pentamidine, intravenous acyclovir or oral acyclovir or other bone marrow or renal toxic drugs may not tolerate concomitant ddC. If these drugs are given concomitantly with ddC, patients should have frequent clinical and laboratory assessments, as appropriate. Drugs that are nephrotoxic or have the potential to cause peripheral neuropathy might be expected to cause increased toxicity when co-administered with ddC. Drugs that could cause serious additive toxicity when co-administered with study medication will be allowed for treatment of an acute intercurrent illness or opportunistic infection at the discretion of the investigator. Their use may be allowed with interruption of study drug for up to 35 days per episode, for a total of 90 days for the study. If the patient's condition requires chronic administration of these medications, the patient will be discontinued from study medication and followed.
