Multicenter Trial for the Evaluation of a Fixed Dose Combined Tablet for the Treatment of Pulmonary Tuberculosis


Brief description of study

The use of fixed-dose combined (FDC) drugs in the treatment of tuberculosis by National Tuberculosis Programmes has been recommended by both the International Union Against Tuberculosis and Lung Disease (The Union) and the World Health Organisation. The advantages of FDC drugs include preventing the emergence of drug resistance due to monotherapy, reducing the risk of incorrect dosage, simplifying procurement and prescribing practices, aiding adherence and facilitating directly observed treatment. Recent bioavailability studies of four-drug FDC tablets have demonstrated satisfactory results. In this study, we are testing the efficacy of this compound, when given in the initial intensive phase of treatment of patients with newly diagnosed smear positive pulmonary tuberculosis. This will be followed by four months treatment with a two-drug FDC of rifampicin and isoniazid.

Detailed Study Description

This is a multiple country, multicenter study, using the parallel group open-label randomised trial design. The primary objective of this investigation is to assess the efficacy, acceptability and toxicity of a combined FDC regimen of chemotherapy in patients with newly diagnosed smear positive pulmonary tuberculosis in comparison with the standard regimen using separate drugs. Patients will be allocated at random either : - an initial intensive phase of eight weeks of daily ethambutol, isoniazid, rifampicin and pyrazinamide, in a fixed dose COMBINED tablet, followed by 18 weeks of rifampicin and isoniazid, in a fixed dose combined tablet three times a week (2COMB/4(RH)3) or - the same drugs given in SEPARATE formulations in the initial intensive phase of eight weeks, followed by 18 weeks of rifampicin and isoniazid, in a fixed dose combined tablet, three times a week (2SEPA/4(RH)3)
