Prospective, Randomized, Blinded Phase II Pharmacokinetic/Pharmacodynamic Study of the Efficacy and Tolerability of Levofloxacin in Combination With Optimized Background Regimen for the Treatment of MDR-TB
Abstract
Multi-drug-resistant tuberculosis (MDR-TB) affects nearly 600,000 persons each year around the world. This type of tuberculosis is very difficult to treat, and many patients die from it. Drugs of the fluoroquinolone class are very important for treating MDR-TB, but the best dose of one of the most effective fluoroquinolones, levofloxacin, is not known. This application proposes a study to determine the best dose of levofloxacin to use in treating MDR-TB. 120 patients will receive their usual treatment, plus levofloxacin at one of four doses. The study will be performed in Peru and in South Africa, where MDR-TB is common.
Conditions: Tuberculosis, Multidrug-Resistant.
Primary outcome: Time to Sputum Culture Conversion; Number of Grade 3,4, and 5 AEs.
Enrollment: 111 participants.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 111 participants or records.
