Clinical Trials for Zalcitabine

Trial ID Title Status Sponsor Phase Summary
NCT00000625 A Randomized, Double-Blind Phase II/III Trial of Monotherapy vs. Combination Therapy With Nucleoside Analogs in HIV-Infected Persons With CD4 Cells of 200-500/mm3 Completed Bristol-Myers Squibb Phase 2 To determine the efficacy and safety of zidovudine ( AZT ) versus didanosine ( ddI ), AZT plus ddI, and AZT plus zalcitabine ( ddC ) in preventing disease progression in HIV-infected patients with CD4 counts of 200-500 cells/mm3.
NCT00000625 A Randomized, Double-Blind Phase II/III Trial of Monotherapy vs. Combination Therapy With Nucleoside Analogs in HIV-Infected Persons With CD4 Cells of 200-500/mm3 Completed Glaxo Wellcome Phase 2 To determine the efficacy and safety of zidovudine ( AZT ) versus didanosine ( ddI ), AZT plus ddI, and AZT plus zalcitabine ( ddC ) in preventing disease progression in HIV-infected patients with CD4 counts of 200-500 cells/mm3.
NCT00000625 A Randomized, Double-Blind Phase II/III Trial of Monotherapy vs. Combination Therapy With Nucleoside Analogs in HIV-Infected Persons With CD4 Cells of 200-500/mm3 Completed National Institute of Allergy and Infectious Diseases (NIAID) Phase 2 To determine the efficacy and safety of zidovudine ( AZT ) versus didanosine ( ddI ), AZT plus ddI, and AZT plus zalcitabine ( ddC ) in preventing disease progression in HIV-infected patients with CD4 counts of 200-500 cells/mm3.
NCT00000651 A Randomized, Double Blind, Comparative Study of Dideoxycytidine (ddC) Alone or ddC/AZT Combination Versus Zidovudine (ZDV) Alone in Patients With HIV Infection Who Have Received Prior ZDV Therapy Completed Glaxo Wellcome Phase 3 To evaluate the safety of zalcitabine (dideoxycytidine; ddC) alone and in combination with zidovudine (AZT) versus AZT alone when administered to asymptomatic patients with a CD4 count = or < 200 cells/mm3 and symptomatic patients with a CD4 count = or < 300 cells/mm3. To compare the effectiveness of ddC alone and in combination with AZT versus AZT alone. ddC has been shown to demonstrate an antiviral effect. AZT has been shown to significantly decrease mortality and reduce the frequency of opportunistic infections in patients with AIDS or advanced ARC. After 1 year of AZT therapy, the effectiveness tends to diminish and patients progress with more opportunistic infections and higher mortality rates. Because of the demonstrated antiviral activity, absence of hematologic toxicity, and lack of cross tolerance in laboratory studies of ddC, a study to investigate the long-term effectiveness of ddC in patients with HIV infection who have received AZT therapy is warranted.
NCT00000651 A Randomized, Double Blind, Comparative Study of Dideoxycytidine (ddC) Alone or ddC/AZT Combination Versus Zidovudine (ZDV) Alone in Patients With HIV Infection Who Have Received Prior ZDV Therapy Completed Hoffmann-La Roche Phase 3 To evaluate the safety of zalcitabine (dideoxycytidine; ddC) alone and in combination with zidovudine (AZT) versus AZT alone when administered to asymptomatic patients with a CD4 count = or < 200 cells/mm3 and symptomatic patients with a CD4 count = or < 300 cells/mm3. To compare the effectiveness of ddC alone and in combination with AZT versus AZT alone. ddC has been shown to demonstrate an antiviral effect. AZT has been shown to significantly decrease mortality and reduce the frequency of opportunistic infections in patients with AIDS or advanced ARC. After 1 year of AZT therapy, the effectiveness tends to diminish and patients progress with more opportunistic infections and higher mortality rates. Because of the demonstrated antiviral activity, absence of hematologic toxicity, and lack of cross tolerance in laboratory studies of ddC, a study to investigate the long-term effectiveness of ddC in patients with HIV infection who have received AZT therapy is warranted.
NCT00000651 A Randomized, Double Blind, Comparative Study of Dideoxycytidine (ddC) Alone or ddC/AZT Combination Versus Zidovudine (ZDV) Alone in Patients With HIV Infection Who Have Received Prior ZDV Therapy Completed National Institute of Allergy and Infectious Diseases (NIAID) Phase 3 To evaluate the safety of zalcitabine (dideoxycytidine; ddC) alone and in combination with zidovudine (AZT) versus AZT alone when administered to asymptomatic patients with a CD4 count = or < 200 cells/mm3 and symptomatic patients with a CD4 count = or < 300 cells/mm3. To compare the effectiveness of ddC alone and in combination with AZT versus AZT alone. ddC has been shown to demonstrate an antiviral effect. AZT has been shown to significantly decrease mortality and reduce the frequency of opportunistic infections in patients with AIDS or advanced ARC. After 1 year of AZT therapy, the effectiveness tends to diminish and patients progress with more opportunistic infections and higher mortality rates. Because of the demonstrated antiviral activity, absence of hematologic toxicity, and lack of cross tolerance in laboratory studies of ddC, a study to investigate the long-term effectiveness of ddC in patients with HIV infection who have received AZT therapy is warranted.
NCT00000653 A Trial of Two Doses of 2',3'-Dideoxycytidine (ddC) in the Treatment of Children With Symptomatic HIV Infection Who Are Intolerant of AZT and/or Who Show Progressive Disease While on AZT Completed Hoffmann-La Roche Phase 2 To evaluate and compare the long-term (48-177 weeks) safety, tolerance, and efficacy of two doses of zalcitabine ( dideoxycytidine; ddC ) taken orally every 8 hours in children with symptomatic HIV infection who have one of the following: intolerance to zidovudine ( AZT ) (development of toxicity during prolonged AZT therapy), demonstrated disease progression after 6 months of AZT therapy, OR both AZT intolerance and disease progression after 6 months of AZT therapy. As useful as AZT appears to be in the treatment of patients infected with HIV, it is associated with significant toxicity in some patients, and it does not prevent ultimate progression to AIDS and eventual mortality. Thus, there is a clear need for new antiretroviral drugs, and ddC is one such promising agent.
