Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The recommended treatment for latent tuberculosis infection for adults is a daily dose of isoniazid 300mg during 6 months. In Brazil, isoniazid was formulated as 100 mg tables. The treatment duration and the high pill burden compromised patient adherence to the treatment. The Brazilian National Programme for Tuberculosis requested the development of a new 300mg isoniazid formulation. The aim of the study is to compare the bioavailability of the isoniazid 300mg new formulation and three 100mg tablets of the reference formulation.

The study is a randomized, single dose, open label, fasting, two-phase crossover bioequivalence study with a wash out period of 7 days (\>7 half-life) in 28 healthy human volunteers. For the determination of isoniazid in human plasma, the investigators developed and validated a sensitive, simple and rapid HPLC-MS/MS method.

This will support the strategy adopted by the Brazilian National Program for Tuberculosis for the treatment of latent tuberculosis. The new formulation will increase patients' adherence to the treatment and quality of life. Medical doctors in Brazil should become aware of the new formulation and the new treatment strategy in order to prescribe the right medication and avoid errors that could result in a high frequency of adverse events. Future research studies should evaluate pharmacovigilance, acceptability of the new tablet formulation and its impact on the cure rate.
