A Randomized Trial of the Efficacy and Safety of a Strategy of Starting with Nelfinavir Versus Ritonavir Added to Background Antiretroviral (AR) Nucleoside Therapy in HIV-Infected Individuals with CD4+ Cell Counts Less than or Equal to 200/mm3 Clinical research trials and A Randomized Trial of the Efficacy and Safety of a Strategy of Starting with Nelfinavir Versus Ritonavir Added to Background Antiretroviral (AR) Nucleoside Therapy in HIV-Infected Individuals with CD4+ Cell Counts Less than or Equal to 200/mm3 health trials happen in many of localities throughout the U.S.. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials typically measure the effectualness of new drugs. The function of the studies / projects is to resolve particular human medical questions. Clinical trials are a popular manner for mDs, government agencies, and private sector corporations to discover remedies for all varieties of circumstances, like A Randomized Trial of the Efficacy and Safety of a Strategy of Starting with Nelfinavir Versus Ritonavir Added to Background Antiretroviral (AR) Nucleoside Therapy in HIV-Infected Individuals with CD4+ Cell Counts Less than or Equal to 200/mm3. A Randomized Trial of the Efficacy and Safety of a Strategy of Starting with Nelfinavir Versus Ritonavir Added to Background Antiretroviral (AR) Nucleoside Therapy in HIV-Infected Individuals with CD4+ Cell Counts Less than or Equal to 200/mm3 Clinical Trials and other clinical trials allow volunteers to obtain healthcare treatment options before they are available to the masses. Some times the participants undergo professional assistance for free of charge, and occasionally they are paid for their time. Sometimes there is a cost for a A Randomized Trial of the Efficacy and Safety of a Strategy of Starting with Nelfinavir Versus Ritonavir Added to Background Antiretroviral (AR) Nucleoside Therapy in HIV-Infected Individuals with CD4+ Cell Counts Less than or Equal to 200/mm3 clinical trial.

A Randomized Trial of the Efficacy and Safety of a Strategy of Starting with Nelfinavir Versus Ritonavir Added to Background Antiretroviral (AR) Nucleoside Therapy in HIV-Infected Individuals with CD4+ Cell Counts Less than or Equal to 200/mm3
For Condition: HIV Infections
Status: No longer recruiting
Sponsor(s): National Institute of Allergy and Infectious Diseases (NIAID) ,
Synopsis: To compare nelfinavir (NFV) with ritonavir (RTV) for delaying disease progression or death in HIV-infected patients with CD4+ cell counts less than 100 cells/mm3 [AS PER AMENDMENT 3/11/98: less than or equal to 200 cells/mm3]. To compare NFV with RTV for the development of adverse events and for rates of permanent discontinuation of study medication. [AS PER AMENDMENT 10/02/97: To compare by intention-to-treat analysis for disease progression, including death, the following two regimens: NFV plus background combination antiretroviral (AR) therapy followed by indinavir (IDV) or RTV in the event of significant intolerance; and RTV plus AR therapy followed by IDV, then NFV, in the event of significant intolerance.] [AS PER AMENDMENT 3/11/98: SUBSTUDY CPCRA 045: To determine the relative rates of emergence of HIV-1 resistance and to compare changes in plasma HIV RNA levels and CD4+ cell counts in a sample of patients with CD4+ cell counts <= 200/mm3 who are enrolled in protocol CPCRA 042.] AR therapy is rapidly becoming the standard of care for the treatment of HIV infection. AR therapy provides the best opportunity for maximizing viral suppression, reducing toxicity and delaying the emergence of resistant strains. The newest class of AR agents, the HIV protease inhibitors, exhibits the most potent anti-HIV effects described to date. This study will compare 2 protease inhibitors, NFV and RTV for efficacy and safety in a population with advanced HIV disease, who are taking various background nucleoside therapies.
Details: AR therapy is rapidly becoming the standard of care for the treatment of HIV infection. AR therapy provides the best opportunity for maximizing viral suppression, reducing toxicity and delaying the emergence of resistant strains. The newest class of AR agents, the HIV protease inhibitors, exhibits the most potent anti-HIV effects described to date. This study will compare 2 protease inhibitors, NFV and RTV for efficacy and safety in a population with advanced HIV disease, who are taking various background nucleoside therapies. Eligible patients will be randomized either to NFV plus background AR nucleoside therapy or to RTV plus background AR nucleoside therapy. Background AR therapy may also be no background therapy, although use of protease inhibitors as monotherapy is not recommended unless there is no alternative. Patients will be allowed to cross over to the alternate protease inhibitor if they reach a primary study endpoint. Data will be collected every 4 months. [AS PER AMENDMENT 10/2/97: Patients assigned to the NFV arm who develop a significant intolerance may switch to RTV or IDV; those assigned to the RTV arm who develop a significant intolerance are encouraged to switch to IDV (NFV allowed if IDV contraindicated). Switchover for intolerance is strongly discouraged during the first 4 weeks of follow-up. Patients initially assigned to NFV therapy who experience disease progression may switch to RTV; if RTV is not tolerated, patients may switch to IDV. Because of the cross-resistance between RTV and IDV, patients who progress on RTV should switch to NFV.] [AS PER AMENDMENT 12/15/98: Patients originally assigned to NFV who experience poor virologic control or disease progression should change to RTV or IDV or enroll in the PIP protocol (CPCRA 057). Conversely, patients originally assigned to RTV should change to NFV or enroll in the PIP protocol (such patients continue to be followed on this study). Because of cross-resistance between RTV and IDV, change from RTV to IDV is discouraged. Determination of poor virologic control or disease progression is at the discretion of the patient's clinician. Change in background antiretroviral therapy should occur at the same time that the protease inhibitor is changed for poor virologic control or progression; the choice of new background antiretroviral agents is at the discretion of the clinician.] Randomization is stratified by clinical site.] [AS PER AMENDMENT 3/11/98: SUBSTUDY CPCRA 045: At least 600 patients (>= 400 from CPCRA sites and >= 200 from CTN sites) will be enrolled in the substudy. These patients will have a plasma sample collected for HIV RNA and genotypic resistance within 30 days prior to randomization, at the 1-month visit, and at the q-4-month study visits thereafter until the end of the study. CD4+ cell counts will be done at the 1-month visit and at the q-4-month study visits until the end of the study. A subset of patients will also have immunophenotyping of CD4+ and CD8+ cell TCR V-beta clones carried out before and during treatment. Another subset of patients at selected sites will have viral cultures performed for phenotypic drug sensitivity testing. Initially, specimens for 50 randomly chosen patients in the group originally assigned RTV will be identified for resistance testing. Of this group, specimens for those who have received RTV/IDV for more than 1 month will be analyzed for genotypic resistance to obtain an estimate of the rate of resistance development and to estimate the risk of disease progression associated with resistance to RTV/ZDV. Based on these estimates, determination will be made of the total number of patients and specimens in both treatment groups in order to address the primary objective of comparing genotypic resistance in the two groups.]

Concurrent Medication: Excluded: - Concomitant use of protease inhibitors. - Concomitant treatments that cannot be discontinued, and in the physician's judgement, should not be taken with NFV or RTV. AS PER AMENDMENT 10/2/97: - For patients randomized to NFV: - Concomitant therapy with terfenadine, astemizole, cisapride, triazolam, midazolam, ergot derivatives, amiodarone, quinidine, or rifampin. For patients randomized to IDV: - Concomitant therapy with terfenadine, astemizole, cisapride, triazolam, midazolam, and rifampin. Patients with any of the following prior symptoms are excluded: AS PER AMENDMENT 10/2/97: - History of clinically significant hypersensitivity reaction to any component of NFV tablets (for patients assigned to NFV therapy). Prior Medication: Excluded: - Prior use of protease inhibitors except SQV. [AS PER AMENDMENT 10/2/97: - Prior use of IDV for more than 4 weeks or other protease inhibitors (except SQV) for any prior duration.]
