pyrazinamide and AIDS Seroconversion

pyrazinamide has been researched along with AIDS Seroconversion in 17 studies

pyrazinecarboxamide : A monocarboxylic acid amide resulting from the formal condensation of the carboxy group of pyrazinoic acid (pyrazine-2-carboxylic acid) with ammonia. A prodrug for pyrazinoic acid, pyrazinecarboxamide is used as part of multidrug regimens for the treatment of tuberculosis.

Trial Overview

Trial Outcomes

Combined Failure of Bacteriological Cure and Relapse as Defined by Culture Using Liquid Media (Mycobacteria Growth Indicator Tube-MGIT).

The secondary analysis of efficacy outcome was the proportion of patients who had bacteriologically or clinically defined failure or relapse within 18 months after randomization (a composite unfavorable outcome) based on MGIT. Culture-negative status was defined as two negative-culture results at different visits without an intervening positive result. The date of culture-negative status was defined as the date of the first negative-culture result. This status continued until there were two positive cultures, without an intervening negative culture, or until there was a single positive culture that was not followed by two negative cultures. Relapse strains were those shown to be identical on 24-locus Mycobacterial interspersed repetitive units (MIRU) analysis. (NCT00864383)
Timeframe: 18 months (within one year of completion of therapy)

Combined Failure of Bacteriological Cure and Relapse Within One Year of Completion of Therapy as Defined by Culture Using Solid Media (Lowenstein-Jensen - LJ).

The primary efficacy outcome was the proportion of patients who had bacteriologically or clinically defined failure or relapse within 18 months after randomization (a composite unfavorable outcome). Culture-negative status was defined as two negative-culture results at different visits without an intervening positive result. The date of culture-negative status was defined as the date of the first negative-culture result. This status continued until there were two positive cultures, without an intervening negative culture, or until there was a single positive culture that was not followed by two negative cultures. Relapse strains were those shown to be identical on 24-locus Mycobacterial interspersed repetitive units (MIRU) analysis. For the final 18 month study visit when both L-J samples were contaminated or missing, if the subject could not be brought back, liquid medium culture results were used in place of solid medium culture results.

Timeframe: 18 months (within one year of completion of therapy)

Timeframe: 8 weeks

Number of Patients Who Are Culture Negative (Solid LJ Culture)

Number of patients who are TB LJ culture negative at 8 weeks. (NCT00864383)

Timeframe: 18 months (within one year of completion of therapy)

Sensitivity Analyses Assuming All Losses to Follow-up and Non-tuberculous Deaths Have a Favourable Outcome Using Solid (L-J) Media.

"Sensitivity Analysis of Primary Efficacy Results of All Randomized Subjects Imputing Favorable for Missing Outcomes. Analysis is the number of subjects with an unfavorable outcome. Favorable outcome is defined as the number of subjects with a negative TB culture status at 18 months (at or after 72 weeks), who had not already been classified as having an unfavorable outcome, and whose last positive TB culture result (isolated positive culture) was followed by at least two negative culture results." (NCT00864383)
Timeframe: 18 months

Sensitivity Analysis Assuming All Losses to Follow-up and Non-tuberculous Deaths Have an Unfavorable Outcome Using Solid (L-J) Media.

"Sensitivity Analysis of Primary Efficacy Results of All Randomized Subjects Imputing Unfavorable for Missing Outcomes. Analysis is the number of subjects with an unfavorable outcome. Favorable outcome is defined as the number of subjects with a negative TB culture status at 18 months (at or after 72 weeks), who had not already been classified as having an unfavorable outcome, and whose last positive TB culture result (isolated positive culture) was followed by at least two negative culture results." (NCT00864383)
Timeframe: 18 months

Time to First Culture Negative Sputum Sample (LJ Solid Media)

Culture negative for TB using LJ cultures. (NCT00864383)
Timeframe: 18 months

Time to First Culture Negative Sputum Sample (MGIT Liquid Media)

(NCT00864383)
Timeframe: 18 months

Comparison of the Rate of Treatment Success at 18 Months (After Treatment Initiation) Between Arms B and C

Estimation of the lower bound of a one-sided 95% confidence interval of the difference in success rates between arms B and C. If the lower bound is greater than -7%, this will be evidence that the treatment-shortening arm is not inferior to the standard duration arm. (NCT02821832)
Timeframe: 18 months
