None. None. ( 4 )
Warnings and precautions
A mortality imbalance was seen in clinical trials in SIRTURO-treated patients with pulmonary TB due to Mycobacterium tuberculosis resistant to at least rifampin. ( 5.2 ) Hepatotoxicity may occur with use of SIRTURO. Monitor liver-related laboratory tests. Discontinue SIRTURO if evidence of liver injury occurs. ( 5.4 )
5.1QTc Prolongation
SIRTURO prolongs the QTc interval [see Clinical Pharmacology (12.2) ] . Use with drugs that prolong the QTc interval may cause additive QTc prolongation [see Adverse Reactions (6) ] . In Study 4, where SIRTURO was administered with the QTc prolonging drugs clofazimine and levofloxacin, 5% of patients in the 40-week SIRTURO treatment group experienced a QTc ≥500 ms and 43% of patients experienced an increase in QTc ≥60 ms over baseline.
Of the clofazimine- and levofloxacin-treated patients in the 40-week control arm, 7% of patients experienced a QTc ≥500 ms and 39% experienced an increase in QTc ≥60 ms over baseline. Obtain an ECG before initiation of treatment, 2 weeks after initiation, during treatment, as clinically indicated and at the expected time of maximum increase in the QTc interval of the concomitantly administered QTc prolonging drugs (as applicable).
Obtain electrolytes at baseline and during treatment and correct electrolytes as clinically indicated. The following may increase the risk for QTc prolongation when patients are taking SIRTURO: use with other QTc prolonging drugs a history of Torsade de Pointes a history of congenital long QTc syndrome a history of or ongoing hypothyroidism a history of or ongoing bradyarrhythmias a history of uncompensated heart failure serum calcium, magnesium, or potassium levels below the lower limits of normal Discontinue SIRTURO if the patient develops: Clinically significant ventricular arrhythmia A QTc interval of greater than 500 ms (confirmed by repeat ECG) If syncope occurs, obtain an ECG to detect QTc prolongation.
An increased risk of death was seen in the SIRTURO treatment group (9/79, 11.4%) compared to the placebo treatment group (2/81, 2.5%) in one placebo-controlled trial in adults (Study 1; based on the 120 week visit window). One death occurred during the 24 weeks of administration of SIRTURO. The imbalance in deaths is unexplained. No discernible pattern between death and sputum culture conversion, relapse, sensitivity to other drugs used to treat tuberculosis, HIV status, or severity of disease could be observed.
In a subsequent active-controlled trial in adults (Study 4), deaths by Week 132 occurred in 11/211 (5.2%) patients in the 40-week SIRTURO treatment group, 8/202 (4%) patients in the active-control treatment group including four of 29 patients who received SIRTURO as part of a salvage treatment, and 2/143 (1.4%) patients in the 28-week SIRTURO treatment group [see Adverse Reactions (6.1) ] .
5.3Risk of Development of Resistance to Bedaquiline
A potential for development of resistance to bedaquiline in M. tuberculosis exists [see Microbiology (12.4) ]. Bedaquiline must only be used in an appropriate combination regimen for the treatment of pulmonary TB due to M. tuberculosis resistant to at least rifampin and isoniazid, to reduce the risk of development of resistance to bedaquiline [see Indications and Usage (1) ] .
5.4Hepatotoxicity
In clinical trials, more hepatic-related adverse reactions were reported in adults with the use of SIRTURO plus other drugs used to treat TB compared to other drugs used to treat TB without the addition of SIRTURO. Alcohol and other hepatotoxic drugs should be avoided while on SIRTURO, especially in patients with impaired hepatic function. Hepatic-related adverse reactions have also been reported in pediatric patients 5 years of age and older [see Adverse Reactions (6.1) ] .
Monitor symptoms (such as fatigue, anorexia, nausea, jaundice, dark urine, liver tenderness and hepatomegaly) and laboratory tests (ALT, AST, alkaline phosphatase, and bilirubin) at baseline, monthly while on treatment, and as needed. Test for viral hepatitis and discontinue other hepatotoxic medications if evidence of new or worsening liver dysfunction occurs. Discontinue SIRTURO if: transaminase elevations are accompanied by total bilirubin elevation greater than two times the upper limit of normal transaminase elevations are greater than eight times the upper limit of normal transaminase elevations are greater than five times the upper limit of normal and persist beyond two weeks
5.5Drug Interactions CYP3A4 Inducers Coadministration of
SIRTURO with a moderate or strong CYP3A4 inducer decreases the systemic exposure of bedaquiline and may reduce the therapeutic effect of SIRTURO. Avoid coadministration of SIRTURO with moderate or strong CYP3A4 inducers, such as efavirenz and rifamycins (i.e., rifampin, rifapentine and rifabutin) [see Drug Interactions (7.1) ] . CYP3A4 Inhibitors Coadministration of SIRTURO with CYP3A4 inhibitors increases the systemic exposure of bedaquiline, which may increase the risk of adverse reactions.
Closely monitor patient safety (e.g., liver function) when SIRTURO is coadministered with CYP3A4 inhibitors [see Drug Interactions (7.1) ] .
Interactions
Avoid use of strong and moderate CYP3A4 inducers with SIRTURO. ( 7.1 ) Closely monitor patient safety (e.g., liver function) when SIRTURO is coadministered with CYP3A4 inhibitors. ( 5.4 , 7.1 )
7.1Effect of Other Drugs on
SIRTURO Strong and Moderate CYP3A4 Inducers Coadministration of SIRTURO with moderate or strong CYP3A4 inducers may decrease systemic exposure of bedaquiline. Avoid coadministration of SIRTURO with strong or moderate CYP3A4 inducers [see Clinical Pharmacology (12.3) ] . CYP3A4 Inhibitors Coadministration of SIRTURO with CYP3A4 inhibitors increases the systemic exposure of bedaquiline which may increase the risk of adverse reactions.
Closely monitor patient safety (e.g., liver function) when SIRTURO is coadministered with CYP3A4 inhibitors. No dose adjustment of SIRTURO is needed when coadministered with CYP3A4 inhibitors [see Clinical Pharmacology (12.3) ] .
7.2Other Antimicrobial Medications
No dose adjustment of isoniazid or pyrazinamide is required during coadministration with SIRTURO. In a placebo-controlled clinical trial in adult patients, no major impact of coadministration of SIRTURO on the pharmacokinetics of ethambutol, kanamycin, pyrazinamide, ofloxacin or cycloserine was observed.
7.3QTc Interval Prolonging Drugs
In clinical trials of adult patients, additional QTc interval prolongation was observed during combination treatment with SIRTURO and other QTc prolonging drugs. In Study 3, concurrent use of clofazimine with SIRTURO resulted in QTc prolongation: mean increases in QTc were larger in the 17 adult patients who were taking clofazimine with bedaquiline at Week 24 (mean change from Day-1 of 32 ms) than in patients who were not taking clofazimine with bedaquiline at Week 24 (mean change from Day-1 of 12 ms).
Monitor ECGs if SIRTURO is coadministered to patients receiving other drugs that prolong the QTc interval, and discontinue SIRTURO if there is evidence of serious ventricular arrhythmia or QTc interval greater than 500 ms [see Warnings and Precautions (5.1) and Clinical Pharmacology (12.2) ] . ECG monitoring should be performed prior to initiation and at the expected time of maximum increase in the QTc interval of the concomitantly administered QTc prolonging drugs.
Pregnancy and breastfeeding
8.1Pregnancy Risk Summary
Available data from published literature of SIRTURO use in pregnant women are insufficient to evaluate a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. There are risks associated with active TB during pregnancy (see Clinical Considerations ) . Reproduction studies performed in rats and rabbits have revealed no evidence of harm to the fetus due to oral administration of bedaquiline to pregnant rats and rabbits during organogenesis at exposures up to 6 times the clinical dose based on AUC comparisons (see Data ) .
The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk Active TB in pregnancy is associated with adverse maternal and neonatal outcomes including maternal anemia, caesarean delivery, preterm birth, low birth weight, birth asphyxia, and perinatal infant death.
Data Animal Data Pregnant rats were treated with bedaquiline at 5, 15 and 45 mg/kg (approximately 0.7, 2 and 6 times the clinical dose based on AUC comparisons) during the period of organogenesis (gestational Days 6 to 17, inclusive). Pregnant rabbits were treated with bedaquiline at 10, 30 and 100 mg/kg (approximately 0.05, 0.2 and 1.5 times the clinical dose based on AUC comparisons) during the period of organogenesis (gestational Days 6 to 19, inclusive).
No embryotoxic effects were found in rats or rabbits at dose exposures up to 6 times the clinical dose exposures based on AUC comparisons.

6.1Clinical Studies Experience
Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to the rates in the clinical studies of another drug and may not reflect the rates observed in clinical practice. Refer to the prescribing information of the drugs used in combination with SIRTURO for their respective adverse reactions. Clinical Studies Experience in Adults Adverse reactions for SIRTURO were identified from safety data from 335 patients who received SIRTURO for eight weeks (Study 2) and 24 weeks (Studies 1 and 3), and 354 patients who received SIRTURO for 40 weeks or 28 weeks (Study 4).
In these studies, patients received SIRTURO in combination with other antimycobacterial drugs. Studies 1 and 2 were randomized, double-blind, placebo-controlled trials in newly diagnosed patients with pulmonary TB due to M. tuberculosis resistant to at least rifampin and isoniazid. Study 3 was an open-label, noncomparative study with SIRTURO administered as part of an individualized treatment regimen in previously treated patients with pulmonary TB due to M. tuberculosis resistant to at least rifampin and isoniazid, including patients resistant to second-line injectables and/or fluroquinolones.
In Study 1, 35% were Black, 17% were Hispanic, 13% were White, 9% were Asian, and 26% were of another race. Eight of 79 (10%) patients in the SIRTURO group and 16 of 81 (20%) patients in the placebo treatment group were HIV infected. Seven (8.9%) SIRTURO-treated patients and six (7.4%) placebo-treated patients discontinued Study 1 because of an adverse reaction. Study 4 was an open-label, randomized, active-controlled trial in patients with pulmonary TB due to M. tuberculosis resistant to at least rifampin that evaluated a 40-week arm of SIRTURO in combination with other oral antimycobacterial drugs compared with a 40-week active control arm that included an injectable antimycobacterial drug in combination with other oral antimycobacterial drugs.
A 28-week arm including SIRTURO, an injectable and other antimycobacterial drugs, was also evaluated in the trial, but recruitment was stopped early due to changes in the standard of care. In the population treated in the two 40-week arms (N=413), the median age was 32.8 years, 61% were male, 46% were Asian, 36% were Black, 18% were White and 16% were HIV infected. Common Adverse Reactions Table 3 presents select adverse reactions that occurred more frequently in the SIRTURO arm than the placebo arm in Study 1.
The most common adverse reactions reported in 10% or more patients treated with SIRTURO and occurred more frequently than the placebo arm were nausea, arthralgia, headache, hemoptysis and chest pain.

Transaminase Elevations In both Studies 1 and 2, transaminase elevations of at least 3 times the upper limit of normal developed more frequently in the SIRTURO treatment group (11/102 [10.8%] vs 6/105 [5.7%]) than in the placebo treatment group. In Study 3, 22/230 (9.6%) patients had alanine aminotransferase (ALT) or aspartate aminotransferase (AST) greater than or equal to 3 times the upper limit of normal during the overall treatment period.
In Study 4 during the treatment phase, transaminase elevations of at least 3 times the upper limit of normal developed in 45/211 (21%) in the 40-week SIRTURO treatment group, 45/202 (22%) in the 40-week active comparator group, and 23 /143 (16%) in the 28-week SIRTURO-containing group. Table 4 presents select adverse reactions occurring in 5% or greater of patients receiving SIRTURO in combination with other antimycobacterial drugs in the 40-week SIRTURO arm in Study 4.
The most common adverse reactions reported in 10% or more patients in the 40-week SIRTURO arm were QTc prolongation, nausea, vomiting, arthralgia, transaminases increased, abdominal pain, pruritus, dizziness, headache, chest pain, rash, insomnia, dry skin, and palpitations.
