SIRTURO is a diarylquinoline antimycobacterial drug indicated as part of combination therapy in adults ( ≥ 18 years) with pulmonary multi-drug resistant tuberculosis (MDR-TB). Reserve SIRTURO for use when an effective treatment regimen cannot otherwise be provided. SIRTURO should be administered by directly observed therapy (DOT).
This indication is based on analysis of time to sputum culture conversion from two controlled Phase 2 trials in patients with pulmonary MDR-TB.
Limitations of Use
The safety and efficacy of SIRTURO for the treatment of latent infection due to Mycobacterium tuberculosis have not been established. The safety and efficacy of SIRTURO for the treatment of drug-sensitive TB have not been established. In addition, there are no data on the treatment with SIRTURO of extra-pulmonary TB (e.g., central nervous system). The safety and efficacy of SIRTURO for the treatment of infections caused by non-tuberculous mycobacteria (NTM) have not been established. Therefore, use of SIRTURO in these settings is not recommended.
DOSAGE AND ADMINISTRATION
SIRTURO should only be used in combination with at least 3 other drugs to which the patient's MDR-TB isolate has been shown to be susceptible in vitro. If in vitro testing results are unavailable, treatment may be initiated with SIRTURO in combination with at least 4 other drugs to which the patient's MDR-TB isolate is likely to be susceptible.
Throughout treatment with, and following the last intake of SIRTURO, patients should continue to take their companion drugs as directed.
The recommended dosage of SIRTURO is:
- Weeks 1-2: 400 mg (4 tablets of 100 mg) once daily with food
- Weeks 3-24: 200 mg (2 tablets of 100 mg) 3 times per week with food (with at least 48 hours between doses) for a total dose of 600 mg per week.
The total duration of treatment with SIRTURO is 24 weeks. The SIRTURO tablet should be swallowed whole with water. Patients should avoid alcohol use while on treatment.
Patients should be advised of the need to take SIRTURO as prescribed. Compliance with the full course of therapy must be emphasized.
If a dose is missed during the first 2 weeks of treatment, patients should not make up the missed dose but should continue the usual dosing schedule. From Week 3 onwards, if a 200 mg dose is missed, patients should take the missed dose as soon as possible, and then resume the 3 times a week regimen.
