Indications for SIRTURO:
As part of combination therapy in pulmonary multi-drug resistant tuberculosis (MDR-TB) only when an effective treatment regimen cannot otherwise be provided.
Limitations Of use:
Safety and efficacy for treatment of latent infection, drug-sensitive or extra-pulmonary tuberculosis (eg, CNS), non-tuberculous mycobacterial infections, or use in HIV-infected patients have not been established.
Administer by directly observed therapy and in combination with ≥3 other drugs to which the isolate is susceptible. Swallow whole with water. Take with food. ≥18yrs: 400mg once daily for 2 weeks followed by 200mg three times weekly (≥48hrs between doses) for 22 weeks.
<18yrs: not established.
Increased risk of mortality. Increased risk of QT prolongation in patients with history of Torsade de Pointes, congenital long QT syndrome, hypothyroidism, bradyarrhythmias, uncompensated heart failure, electrolyte abnormalities; monitor closely. Obtain ECG prior to therapy, and at least 2, 12, and 24 weeks after starting. Correct any electrolyte abnormalities at baseline and monitor if QT prolongation is detected. Discontinue Sirturo and all other QT prolonging drugs if ventricular arrhythmia or QTcF interval >500ms develops. Monitor ALT/AST, phosphatase, bilirubin at baseline, monthly during treatment, and as needed. Test for viral hepatitis and discontinue other hepatotoxic drugs if serum aminotransferases >3XULN (repeat testing within 48hrs). Discontinue if aminotransferase elevation with total bilirubin >2XULN, aminotransferase elevation >8XULN, or >5XULN that persists >2 weeks. Severe hepatic or severe renal impairment/ESRD. Pregnancy (Cat.B). Nursing mothers: not recommended.
Avoid concomitant use with strong CYP3A4 inducers (eg, rifampin, rifapentine, rifabutin). Avoid concomitant use with strong CYP3A4 inhibitors (eg, ketoconazole) for >14 days; monitor. Avoid concomitant moderate CYP3A inducers (eg, efavirenz). Additive QT prolongation with other drugs that prolong the QT interval (eg, fluoroquinolones, macrolides, clofazimine). Avoid alcohol and other hepatotoxic drugs. Sirturo exposure increased with Kaletra (caution).
Nausea, arthralgia, headache, hemoptysis, chest pain, anorexia, increased transaminases; arrhythmias, syncope (obtain ECG), hepatic dysfunction.
