Comparison of 3-month Once-weekly Isoniazid Plus Rifapentine, 4-month Daily Rifampicin, and 3-month Daily Isoniazid Plus Rifampicin for the Treatment Latent Tuberculosis in Patients With End-stage Kidney Disease: A Randomised Clinical Trial
Comparison of 3-month Once-weekly Isoniazid Plus Rifapentine, 4-month Daily Rifampicin, and 3-month Daily Isoniazid Plus Rifampicin for the Treatment Latent Tuberculosis in Patients With End-stage Kidney Disease: A Randomised Clinical Trial
Objective To determine if treatment completion with a 4-month rifampin (4R) or 3-month rifapentine (P) + isoniazid (H) weekly for 12 weeks (3HP) regimens is better than with a 3-month (3HR) regimen for treatment of latent tuberculosis (TB) infection (LTBI) in patients with end stage kidney disease.
Methods Design: Multicenter, prospective, parallel-group, open-label, controlled clinical trial.
Study population: All adult patients with ESKD in who treatment for LTBI is prescribed at 7 hospitals.
Interventions: Patients who accept participation, will be randomly assigned to one of the 3 arms: 3HR (control) (90 doses), 4R (120 doses) or 3HP (12 doses).
Outcome: Proportion of participants who discontinue permanently the assigned treatment. Follow-up: Periodic assessment for permanent or temporary discontinuation, and adverse events of the assigned treatment.
Sample size: 225 subjects (75 per arm) will be needed to demonstrate, if exists, a 0.16 decrease in permanent discontinuation rates in the experimental arms (4R and 3HP) with respect to the control arm (3HR), with α= 0.025, β= 0.20, and 5% expected losses, and assuming a 0.25 proportion of permanent discontinuation in the control.
