Phase 4
Conditions

Interventions
Registration Number
NCT04766307
Lead Sponsor
Beijing Chest Hospital
Brief Summary

The purpose of the study is to compare the efficacy and safety of standard chemotherapy regimen 2HRZE/4HR plus IL-2 and standard regimen 2HRZE/4HR for newly diagnosed smear positive pulmonary tuberculosis.

Detailed Description

1. Design:The study is a multi-center, randomized, controlled, open clinical trial.

2. Population:Initial smear positive pulmonary tuberculosis patients who fulfill the inclusion and exclusion criteria.

3. Investigational regimens:

Experimental group regimen:2HRZE/4HR+Interleukin-2 (500000 units daily, subcutaneous injection in the first month) The control group regimen: 2HRZE/4HR Dosage: isoniazid 300mg(given once daily),rifampin 450mg(less than 50kg,given once daily) or 600mg(more than 50kg,given once daily),pyrazinamide 1500mg(less than 50kg,given once daily) or 30mg/kg(more than 50kg,given once daily),ethambutol 750mg(less than 50kg,given once daily) or 1000mg(more than 50kg,given once daily).

4. Primary and Secondary outcome measures:

primary efficacy outcome measures:(a)Negative conversion rate of sputum bacteria. (b)Sputum smear conversion proportion at the treatment completion .

secondary efficacy outcome measure:Recurrence rate after treatment.

Primary Outcome Measures
NameTimeMethod
The primary study endpoint was the proportion of subjects who had converted their sputum cultures to negative at the end of treatment.two-month course intensive phase treatment, followed by a four-month consolidation phase treatment.Some TB patients with cavity should receive 9 total months (7 months of continuation therapy after the initial 2-month intensive phase).

A cure was defined as who was smear- or culture-negative in the last month of treatment and on at least one previous occasion. Treatment completion was defined as patients who completed treatment but who does not have a negative sputum smear or culture result in the last month of treatment and on at least one previous occasion. Treatment failure was defined as patients whose sputum smear or culture is positive at 5 months or later during treatment.
