Azithromycin as Host-directed Therapy for Pulmonary Tuberculosis

Status Completed

Clinical Trial Summary

Rationale: Treatment in tuberculosis (TB) is focused on eradication of the bacterial infection, however, after treatment approximately half of patients are left with a significant and permanent respiratory impairment. Adjunctive host-directed therapies are being investigated to modulate host immune responses to target mycobacterium tuberculosis (Mtb) infection and/or reduce excessive inflammation, prevent pathological tissue damage, preserve lung function and enhance effectiveness of standard drug therapy, while nonetheless eliminating Mtb. Macrolide antibiotics have previously been used in the treatment of multidrug-resistant TB. In addition to their antibiotic effects, macrolides have also been recognized to induce anti-inflammatory and immunomodulatory effects in other lung diseases. Objective: To investigate the immunomodulatory effects of azithromycin in tuberculosis patients receiving standard therapy (isoniazid, rifampicin, pyrazinamide, ethambutol (HRZE)) Study design: A prospective, randomized open label intervention trial to investigate the immunomodulatory effects of azithromycin Study population: 24 Intervention: azithromycin 250 mg once daily or standard of care (control) Main study parameters/endpoints: 1. To assess whether azithromycin enhances resolution of systemic inflammation in patients with drug susceptible pulmonary TB receiving standard treatment. 2. To assess whether azithromycin on top of standard treatment in patients with drug susceptible pulmonary TB reduces airway inflammation and reduces tissue degradation and remodeling 3. To investigate whether these effects are associated within shortening of the time to sputum conversion.
