We aren't docs. Always confer with your doctor about A Phase I Concentration-Controlled Trial to Assess the Safety, Tolerance, Pharmacokinetics and Development of Decreased HIV-1 Susceptibility to the Combination of Atevirdine Mesylate (U-87201E), Zidovudine (AZT), and Didanosine (ddI) conditions. Clinical Trials Search.org is a website committed to listing clinical research studies in human subjects. A Phase I Concentration-Controlled Trial to Assess the Safety, Tolerance, Pharmacokinetics and Development of Decreased HIV-1 Susceptibility to the Combination of Atevirdine Mesylate (U-87201E), Zidovudine (AZT), and Didanosine (ddI) Clinical research trials and A Phase I Concentration-Controlled Trial to Assess the Safety, Tolerance, Pharmacokinetics and Development of Decreased HIV-1 Susceptibility to the Combination of Atevirdine Mesylate (U-87201E), Zidovudine (AZT), and Didanosine (ddI) health trials happen in many of cities across the US. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials generally measure the effectualness of new does drugs. The intention of the studies / projects is to figure out particular human healthcare questions. Clinical trials are a popular manner for doctors, government agencies, and private sector corporations to detect cures for all forms of circumstances, like A Phase I Concentration-Controlled Trial to Assess the Safety, Tolerance, Pharmacokinetics and Development of Decreased HIV-1 Susceptibility to the Combination of Atevirdine Mesylate (U-87201E), Zidovudine (AZT), and Didanosine (ddI). A Phase I Concentration-Controlled Trial to Assess the Safety, Tolerance, Pharmacokinetics and Development of Decreased HIV-1 Susceptibility to the Combination of Atevirdine Mesylate (U-87201E), Zidovudine (AZT), and Didanosine (ddI) Clinical Trials and other clinical trials allow for volunteers to undergo medical treatment options before they are available to the general public. Most times the subjects get treatment for free of charge, and occasionally they are paid for their time. Occasionally there is a cost for a A Phase I Concentration-Controlled Trial to Assess the Safety, Tolerance, Pharmacokinetics and Development of Decreased HIV-1 Susceptibility to the Combination of Atevirdine Mesylate (U-87201E), Zidovudine (AZT), and Didanosine (ddI) clinical trial. Subjects frequently get the best healthcare possible for their A Phase I Concentration-Controlled Trial to Assess the Safety, Tolerance, Pharmacokinetics and Development of Decreased HIV-1 Susceptibility to the Combination of Atevirdine Mesylate (U-87201E), Zidovudine (AZT), and Didanosine (ddI) condition. Hazards are a reality, however, and could include more or frequent mD visits, health risks (possibly life-jeopardizing), and/or the treatment being ineffectual. Trials are federally regulated with exacting guidelines to protect clinical trials patients.

A Phase I Concentration-Controlled Trial to Assess the Safety, Tolerance, Pharmacokinetics and Development of Decreased HIV-1 Susceptibility to the Combination of Atevirdine Mesylate (U-87201E), Zidovudine (AZT), and Didanosine (ddI)
For Condition: HIV Infections
Status: Completed
Sponsor(s): National Institute of Allergy and Infectious Diseases (NIAID) , Upjohn,Glaxo Wellcome
Synopsis: Part I: To determine the pharmacokinetic dose for atevirdine mesylate ( U-87201E ) when used in combination with zidovudine ( AZT ). To determine the pharmacokinetic profiles of U-87201E and AZT over a 12-week period. Part II: To determine whether or not decreased viral susceptibility to U-87201E develops when the drug is administered concomitantly with AZT for 12 weeks. Part III: To evaluate the pharmacokinetic effects of ddI/AZT/U-87201E therapy and to assess changes in viral susceptibility to U-87201E. Interest exists in the development of antiretroviral agents that possess different mechanisms of action from nucleoside analogs such as AZT. U-87201E is a non-nucleoside reverse transcriptase (RT) inhibitor that has demonstrated activity against HIV-1; however, an emerging characteristic of non-nucleoside RT inhibitors is the development of rapid resistance to HIV isolates. Whether this resistance can be prevented in the presence of nucleoside analogs such as AZT and ddI has yet to be determined.
Details: Interest exists in the development of antiretroviral agents that possess different mechanisms of action from nucleoside analogs such as AZT. U-87201E is a non-nucleoside reverse transcriptase (RT) inhibitor that has demonstrated activity against HIV-1; however, an emerging characteristic of non-nucleoside RT inhibitors is the development of rapid resistance to HIV isolates. Whether this resistance can be prevented in the presence of nucleoside analogs such as AZT and ddI has yet to be determined. Part I: Five male patients enter a pharmacokinetic concentration-controlled trial of U-87201E plus zidovudine at the University of Rochester site only. A target plasma concentration range at trough for U-87201E will be determined. Pharmacokinetic monitoring continues for 7 days or until the desired dose regimen has been determined. The five patients may be eligible to continue in Part II of the study to complete a total of 12 weeks of therapy. Part II: At least 10 male patients (all sites eligible) in addition to the five patients from Part I receive doses of U-87201E as determined by Part I and AZT at the same dose as in Part I. Therapy is administered for 12 weeks. Patients with no decreased viral susceptibility to U-87201E after 6 weeks may be offered an extension to 24 or more weeks of therapy. Patients are followed weekly for 8 weeks and every other week thereafter until the end of the study. Part III: At least eight patients who have received 24 weeks of U-87201E/AZT have ddI added to the regimen for 12 additional weeks.
