Аннотация
BACKGROUND: Outcomes of treatment of tuberculosis patients with regimens including pretomanid have not yet been systematically reviewed.
OBJECTIVES: To appraise existing evidence on efficacy and safety of pretomanid in tuberculosis.
DATA SOURCES: Pubmed, clinicaltrials.gov. and Cochrane library.
STUDY ELIGIBILITY CRITERIA: Quantitative studies presenting original data on clinical efficacy or safety of pretomanid.
PARTICIPANTS: Patients with tuberculosis.
INTERVENTIONS: Treatment with pretomanid or pretomanid-containing regimens in minimum one study group.
METHODS: Two authors independently extracted data and assessed risk of bias. Data on efficacy (early bactericidal activity, bactericidal activity, end-of-treatment outcomes and acquired resistance) and safety were summarized in tables. Mean differences in efficacy outcomes between regimens across studies were calculated.
RESULTS: Eight studies were included; four randomized controlled trials on 2-week early bactericidal activity in rifampicin-susceptible tuberculosis, three trials with randomized rifampicin-susceptible tuberculosis arms and a single rifampicin-resistant tuberculosis arm (two on 8-week bactericidal activity, one on end-of-treatment outcomes), one single-arm trial with end-of-treatment outcomes in highly resistant tuberculosis. Activity of pretomanid-moxifloxacin-pyrazinamide was superior to standard treatment on daily change in colony-forming units at days 0-2, 0-56 and 7-56 and time to culture conversion in rifampicin-susceptible tuberculosis (hazard ratio: 1.7; 95% CI 1.1-2.7), but not at end of treatment in one study. This study was stopped due to serious hepatotoxic adverse events, including three deaths, in 4% (95% CI 2-8) patients on pretomanid-moxifloxacin-pyrazinamide and none in controls. In patients with uncomplicated rifampicin-resistant tuberculosis on pretomanid-moxifloxacin-pyrazinamide treatment, 91% (95% CI 59-100) had favourable end-of-treatment outcomes. In patients with highly resistant tuberculosis, 90% (95% CI 83-95) on pretomanid-bedaquiline-linezolid had favourable outcomes six months after treatment, but linezolid-related toxicity was frequent. No acquired resistance to pretomanid was reported.
CONCLUSIONS: Evidence suggests an important role for pretomanid in rifampicin-resistant and highly resistant tuberculosis. Trials comparing pretomanid to existing core and companion drugs are needed to further define that role.
