肺结核新药SIRTURO(BEDAQUILINE FUMARATE)TABLET ORAL-120周跟踪结果发表,显著提高治愈率
2012年12月28日,美国FDA批准新的抗结核药物Sirturo(bedaquiline)用于多重耐药的成人结核当其他治疗手段无效时的联合疗法。这是近四十年来FDA首次批准的抗结核药物。
多重耐药性肺结核是结核病之一,它是指对四种主要的抗结核药物异烟肼和利福平无应答反应的一种结核病。结核杆菌通过空气传播,它通常累及肺部,但有时也累及脑、肾和其他脏器。根据美国疾病预防与控制中心(CDC)的数据,2011年有近900万人患上结核病,其中美国有10528例。
2012年12月28日,美国食品与药物管理局(FDA)通过加速审批程序批准了Sirturo(bedaquiline,双芳基喹啉类抗结核药)在无其它替代药物可用时作为成人多重耐药的结核(TB)联合治疗的组成部分。Sirturo是首个获准治疗多重耐药TB的药物,且应与其他药物联合治疗TB.该药通过抑制人体内结核杆菌复制和播散所需的酶而发挥作用。
FDA抗菌药物评估和研究中心办公室主任Edward说:“多重耐药的结核杆菌对全世界造成严重的健康威胁,Sirturo(bedaquiline)为没有其他治疗选择的患者带来了希望。但是,这个药物也有一些严重的危险,医生应确保合理应用该药物,只适用于对其他抗结核治疗无效的患者。”
尽管在一项临床实验中,Sirturo(bedaquiline)组有9名患者死亡,而安慰剂组只有2名,FDA还是加速通过Sirturo(bedaquiline)临床应用的计划。可向Sirturo(bedaquiline)的制造公司求证该药物的前期实验数据集临床有效性和安全性。
纳入440例患者的两项2期临床试验确定了Sirturo的安全性和有效性。第一项试验的患者被随机分为接受其他抗结核药物加Sirturo或其他抗结核药物加安慰剂治疗。正在进行的第二项试验中的患者接受其他抗结核药物加Sirturo治疗。
两项试验中均评估患者痰培养结核菌转阴时间长度(SCC)。第一项试验显示,Sirturo联合治疗组实现SCC的中位时间为83天,而安慰剂联合治疗组为125天。第二项试验显示,SCC的中位时间为57天,支持了第一项试验的结果。临床试验中出现的最常见不良反应包括恶心,关节疼痛和头痛。
Sirturo的说明书和标签中带有加框警示语,他可影响患者的心电活动(QT间期延长),可能会导致心脏节律异常和并可能致命。试验中接受安慰剂治疗的患者中有2例死亡,接受Sirturo治疗的患者中有9例死亡。接受Sirturo治疗的5例死亡患者和接受安慰剂治疗的2例死亡患者似乎与结核相关,但其余接受Sirturo治疗的患者死亡原因与上述原因不一致。
适应证和用途

FULL PRESCRIBING INFORMATION: CONTENTS*
1 INDICATIONS AND USAGE
SIRTURO is a diarylquinoline antimycobacterial drug indicated as part of combination therapy in the treatment of adults (18 years and older) with pulmonary multi-drug resistant tuberculosis (MDR-TB). Reserve SIRTURO for use when an effective treatment regimen cannot otherwise be provided. Administer SIRTURO by directly observed therapy (DOT).
This indication is approved under accelerated approval based on time to sputum culture conversion [see Clinical Studies (14)]. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials.
Limitations of Use:
Do not use SIRTURO for the treatment of:
Latent infection due to Mycobacterium tuberculosis
Drug-sensitive tuberculosis
Extra-pulmonary tuberculosis
Infections caused by non-tuberculous mycobacteria
The safety and efficacy of SIRTURO in the treatment of HIV infected patients with MDR-TB have not been established as clinical data are limited [see Clinical Studies (14)].
2 DOSAGE AND ADMINISTRATION
2.1 Important Administration Instructions
Administer SIRTURO by directly observed therapy (DOT).
Use SIRTURO only in combination with other anti-mycobacterial drugs [see Dosage and Administration (2.3)].
Emphasize the need for compliance with full course of therapy.
2.2 Required Testing Prior to Administration
Prior to treatment with SIRTURO, obtain the following:
Susceptibility information for the background regimen against M. tuberculosis isolate if possible [see Dosage and Administration (2.3)]
ECG [see Warnings and Precautions (5.2)]
Serum potassium, calcium, and magnesium concentrations [see Warnings and Precautions (5.2)]
Liver enzymes [see Warnings and Precautions (5.3)]
2.3 Recommended Dosage in Combination Therapy
Only use SIRTURO 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, SIRTURO treatment may be initiated in combination with at least 4 other drugs to which the patient's MDR-TB isolate is likely to be susceptible. Refer to the prescribing information of the drugs used in combination with SIRTURO.
The recommended dosage of SIRTURO is 400 mg orally once daily for the first two weeks, followed by 200 mg orally three times per week (with at least 48 hours between doses) for 22 weeks (total duration of 24 weeks).
The SIRTURO tablet should be swallowed whole with water and taken with food.
If a dose is missed during the first 2 weeks of treatment, do not administer the missed dose (skip the dose and then continue the daily dosing regimen). From Week 3 onwards, if a 200 mg dose is missed, administer the missed dose as soon as possible, and then resume the 3 times a week dosing regimen.
3 DOSAGE FORMS AND STRENGTHS
SIRTURO tablets, 100 mg are uncoated white to almost white round biconvex with debossing of "T" over "207" on one side and "100" on the other side.
4 CONTRAINDICATIONS
None.
5 WARNINGS AND PRECAUTIONS
5.1 Increased Mortality
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 (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. Only use SIRTURO when an effective treatment regimen cannot otherwise be provided [see Adverse Reactions (6)].
5.2 QT Prolongation
SIRTURO prolongs the QT interval. Obtain an ECG before initiation of treatment, and at least 2, 12, and 24 weeks after starting treatment with SIRTURO. Obtain serum potassium, calcium, and magnesium at baseline and correct if abnormal. Monitor electrolytes if QT prolongation is detected [see Adverse Reactions (6.1) and Drug Interactions (7.4)]. SIRTURO has not been studied in patients with ventricular arrhythmias or recent myocardial infarction.
The following may increase the risk for QT prolongation when patients are receiving SIRTURO:
use with other QT prolonging drugs including fluoroquinolones and macrolide antibacterial drugs and the antimycobacterial drug, clofazimine
a history of Torsade de Pointes
a history of congenital long QT 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
If necessary, bedaquiline treatment initiation could be considered in these patients after a favorable benefit risk assessment and with frequent ECG monitoring.
Discontinue SIRTURO and all other QT prolonging drugs if the patient develops:
Clinically significant ventricular arrhythmia
A QTcF interval of greater than 500 ms (confirmed by repeat ECG)
If syncope occurs, obtain an ECG to detect QT prolongation.
5.3 Hepatotoxicity
More hepatic-related adverse reactions were reported with the use of SIRTURO plus other drugs used to treat tuberculosis compared to other drugs used to treat tuberculosis without the addition of SIRTURO. Alcohol and other hepatotoxic drugs should be avoided while on SIRTURO, especially in patients with impaired hepatic function.
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:
aminotransferase elevations are accompanied by total bilirubin elevation greater than two times the upper limit of normal
aminotransferase elevations are greater than eight times the upper limit of normal
aminotransferase elevations are greater than five times the upper limit of normal and persist beyond two weeks
5.4 Drug Interactions
CYP3A4 inducers/inhibitors
Bedaquiline is metabolized by CYP3A4 and its systemic exposure and therapeutic effect may therefore be reduced during co-administration with inducers of CYP3A4. Avoid co-administration of strong CYP3A4 inducers, such as rifamycins (i.e., rifampin, rifapentine and rifabutin), or moderate CYP3A4 inducers, such as efavirenz, during treatment with SIRTURO [see Drug Interactions (7.1)].
Co-administration of SIRTURO with strong CYP3A4 inhibitors may increase the systemic exposure to bedaquiline, which could potentially increase the risk of adverse reactions. Therefore, avoid the use of strong CYP3A4 inhibitors for more than 14 consecutive days while on SIRTURO, unless the benefit of treatment with the drug combination outweighs the risk [see Drug Interactions (7.1)]. Appropriate clinical monitoring for SIRTURO-related adverse reactions is recommended.
6 ADVERSE REACTIONS
The following serious adverse reactions are discussed elsewhere in the labeling:
Increased mortality [see Warnings and Precautions (5.1)]
QT Prolongation [see Warnings and Precautions (5.2) and Clinical Pharmacology (12.2)]
Hepatotoxicity [see Warnings and Precautions (5.3)]
Drug Interactions [see Warnings and Precautions (5.4)]
6.1 Clinical 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.
Use SIRTURO only in combination with other anti-mycobacterial drugs [see Dosage and Administration (2.3)]. Refer to the prescribing information of the drugs used in combination with SIRTURO for their respective adverse reactions.
Adverse drug reactions for SIRTURO were identified from the pooled safety data from 335 SIRTURO-exposed patients who received 8 weeks (Study 2) and 24 weeks (Studies 1 and 3) at the proposed dose. Studies 1 and 2 were randomized, double-blind, placebo-controlled trial in newly diagnosed patients with pulmonary MDR-TB. In both treatment arms, patients received SIRTURO or placebo in combination with other drugs used to treat MDR-TB. Study 3 was an open-label, noncomparative study with SIRTURO administered as part of an individualized pulmonary MDR-TB treatment regimen in previously treated patients.
In Study 1, 35% were Black, 17.5% were Hispanic, 12.5% were White, 9.4% were Asian, and 25.6% were of another race. Eight of 79 (10.1%) patients in the SIRTURO group and 16 of 81 (19.8%) 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.

Terms represented by 'transaminases increased' included transaminases increased, AST increased, ALT increased, hepatic enzyme increased, and hepatic function abnormal.
No additional unique Adverse Reactions were identified from the uncontrolled Study 3.
In both Studies 1 and 2, aminotransferase 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 or aspartate aminotransferase greater than or equal to 3 times the upper limit of normal during the overall treatment period.
Increased Mortality
In Study 1, there was a statistically significant increased mortality risk by Week 120 in the SIRTURO treatment group compared to the placebo treatment group (9/79 (11.4%) versus 2/81 (2.5%), p-value=0.03, an exact 95% confidence interval of the difference [1.1%, 18.2%]). Five of the 9 SIRTURO deaths and the 2 placebo deaths were tuberculosis-related. One death occurred during the 24-week SIRTURO treatment period. The median time to death for the remaining eight subjects in the SIRTURO treatment group was 329 days after last intake of SIRTURO. The imbalance in deaths is unexplained; no discernible pattern between death and sputum conversion, relapse, sensitivity to other drugs used to treat tuberculosis, HIV status, and severity of disease was observed.
In the open-label Study 3, 6.9% (16/233) subjects died. The most common cause of death as reported by the investigator was TB (9 subjects). All but one subject who died of TB had not converted or had relapsed. The causes of death in the remaining subjects varied.
7 DRUG INTERACTIONS
7.1 CYP3A4 Inducers/Inhibitors
Bedaquiline exposure may be reduced during co-administration with inducers of CYP3A4 and increased during co-administration with inhibitors of CYP3A4.
CYP3A4 Inducers
Due to the possibility of a reduction of the therapeutic effect of bedaquiline because of the decrease in systemic exposure, co-administration of strong CYP3A4 inducers, such as rifamycins (i.e., rifampin, rifapentine and rifabutin), or moderate CYP3A4 inducers should be avoided during treatment with SIRTURO [see Clinical Pharmacology (12.3)].
CYP3A4 inhibitors
Due to the potential risk of adverse reactions to bedaquiline because of the increase in systemic exposure, prolonged co-administration of bedaquiline and strong CYP3A4 inhibitors, such as ketoconazole or itraconazole, for more than 14 consecutive days should be avoided unless the benefit outweighs the risk [see Clinical Pharmacology (12.3)]. Appropriate clinical monitoring for SIRTURO-related adverse reactions is recommended.
7.2 Other Antimicrobial Medications
No dose-adjustment of isoniazid or pyrazinamide is required during co-administration with SIRTURO.
In a placebo-controlled clinical trial in patients with MDR-TB, no major impact of co-administration of SIRTURO on the pharmacokinetics of ethambutol, kanamycin, pyrazinamide, ofloxacin or cycloserine was observed.
7.3 Antiretroviral Medications
Lopinavir/ritonavir
Although clinical data in HIV/MDR-TB co-infected patients on the combined use of lopinavir (400 mg)/ritonavir (100 mg) with SIRTURO are not available, use SIRTURO with caution when co-administered with lopinavir/ritonavir and only if the benefit outweighs the risk [see Clinical Pharmacology (12.3)].
Nevirapine
No dosage adjustment of bedaquiline is required when co-administered with nevirapine [see Clinical Pharmacology (12.3)].
Efavirenz
Concomitant administration of bedaquiline and efavirenz, or other moderate CYP3A inducers, should be avoided [see Warnings and Precautions (5.4)].
7.4 QT Interval Prolonging Drugs
In a drug interaction study of bedaquiline and ketoconazole, a greater effect on QTc was observed after repeated dosing with bedaquiline and ketoconazole in combination than after repeated dosing with the individual drugs. Additive or synergistic QT prolongation was observed when bedaquiline was co-administered with other drugs that prolong the QT interval.
In Study 3, mean increases in QTc were larger in the 17 subjects who were taking clofazimine with bedaquiline at Week 24 (mean change from reference of 31.9 ms) than in subjects who were not taking clofazimine with bedaquiline at Week 24 (mean change from baseline of 12.3 ms). Monitor ECGs if SIRTURO is co-administered to patients receiving other drugs that prolong the QTc interval, and discontinue SIRTURO if evidence of serious ventricular arrhythmia or QTcF interval greater than 500 ms. [see Warnings and Precautions (5.2) and Clinical Pharmacology (12.2)].
8 USE IN SPECIFIC POPULATIONS
8.1 Pregnancy
Pregnancy Category B
Reproduction studies performed in rats and rabbits have revealed no evidence of harm to the fetus due to bedaquiline. In these studies, the corresponding plasma exposure (AUC) was 2-fold higher in rats compared to humans. There are, however, no adequate and well-controlled studies of SIRTURO in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.
8.3 Nursing Mothers
It is not known whether bedaquiline or its metabolites are excreted in human milk, but rat studies have shown that drug is concentrated in breast milk.
In rats, treated with bedaquiline at doses 1 time to 2 times the clinical dose (based on AUC comparisons), concentrations in milk were 6-fold to 12-fold higher than the maximum concentration observed in maternal plasma. Pups from these dams showed reduced body weights compared to control animals throughout the lactation period.
Because of the potential for adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
8.4 Pediatric Use
The safety and effectiveness of SIRTURO in pediatric patients have not been established.
8.5 Geriatric Use
Because of limited data, differences in outcomes or specific risks with SIRTURO cannot be ruled out for patients 65 years of age and older.
8.6 Hepatic Impairment
The pharmacokinetics of bedaquiline were assessed after single-dose administration to subjects with moderate hepatic impairment (Child-Pugh B) [see Clinical Pharmacology (12.3)]. Based on these results, no dose adjustment is necessary for SIRTURO in patients with mild or moderate hepatic impairment. SIRTURO has not been studied in patients with severe hepatic impairment and should be used with caution in these patients only when the benefits outweigh the risks. Clinical monitoring for SIRTURO-related adverse reactions is recommended [see Warnings and Precautions (5.3)].
8.7 Renal Impairment
SIRTURO has mainly been studied in patients with normal renal function. Renal excretion of unchanged bedaquiline is not substantial (less than or equal to 0.001%). No dose adjustment is required in patients with mild or moderate renal impairment. In patients with severe renal impairment or end stage renal disease requiring hemodialysis or peritoneal dialysis, SIRTURO should be used with caution [see Clinical Pharmacology (12.3)]. Monitor for adverse reactions of SIRTURO when administered to patients with severe renal impairment or end stage renal disease requiring hemodialysis or peritoneal dialysis.
10 OVERDOSAGE
There is no experience with the treatment of acute overdose with SIRTURO. Take general measures to support basic vital functions including monitoring of vital signs and ECG (QT interval) in case of deliberate or accidental overdose. Removal of unabsorbed bedaquiline may be achieved by the administration of activated charcoal. Since bedaquiline is highly protein-bound, dialysis is not likely to significantly remove bedaquiline from plasma.
11 DESCRIPTION
SIRTURO (bedaquiline) for oral administration is available as 100 mg strength tablets. Each tablet contains 120.89 mg of bedaquiline fumarate drug substance, which is equivalent to 100 mg of bedaquiline. Bedaquiline is a diarylquinoline antimycobacterial drug.
Bedaquiline fumarate is a white to almost white powder and is practically insoluble in aqueous media. The chemical name of bedaquiline fumarate is (1R, 2S)-1-(6-bromo-2-methoxy-3-quinolinyl)-4-(dimethylamino)-2-(1-naphthalenyl)-1-phenyl-2-butanol compound with fumaric acid (1:1). It has a molecular formula of C32H31BrN2O2∙C4H4O4 and a molecular weight of 671.58 (555.50 + 116.07). The molecular structure of bedaquiline fumarate is the following:


SIRTURO (bedaquiline) contains the following inactive ingredients: colloidal silicon dioxide, corn starch, croscarmellose sodium, hypromellose 2910 15 mPa.s, lactose monohydrate, magnesium stearate, microcrystalline cellulose, polysorbate 20, purified water (removed during processing).
12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Bedaquiline is a diarylquinoline antimycobacterial drug [see Microbiology (12.4)].
12.2 Pharmacodynamics
Bedaquiline is primarily subjected to oxidative metabolism leading to the formation of N-monodesmethyl metabolite (M2). M2 is not thought to contribute significantly to clinical efficacy given its lower average exposure (23% to 31%) in humans and lower antimycobacterial activity (4-fold to 6-fold lower) compared to the parent compound. However, M2 plasma concentrations appeared to correlate with QT prolongation.
Cardiac Electrophysiology
In Study 1, the mean increases in QTcF, corrected using the Fridericia method, were greater in the SIRTURO treatment group compared to the placebo treatment group from the first week of treatment (9.9 ms at Week 1 for SIRTURO and 3.5 ms for placebo). The largest mean increase in QTcF during the 24 weeks of SIRTURO treatment was 15.7 ms compared to 6.2 ms with placebo treatment (at Week 18). After bedaquiline treatment ended, the QTcF gradually decreased, and the mean value was similar to that in the placebo group by study week 60.
In Study 3, where patients with no treatment options received other QT-prolonging drugs used to treat tuberculosis, including clofazimine, concurrent use with SIRTURO resulted in additive QTcF prolongation, proportional to the number of QT prolonging drugs in the treatment regimen. Patients taking SIRTURO alone with no other QT prolonging drug developed a mean QTcF increase over baseline of 23.7 ms with no QTcF segment duration in excess of 480 ms, whereas patients taking at least 2 other QT prolonging drugs developed a mean QTcF prolongation of 30.7 ms over baseline, and resulted in QTcF segment duration in excess of 500 ms in one patient. [See Warnings and Precautions (5.3)]
12.3 Pharmacokinetics
Absorption
After oral administration of SIRTURO maximum plasma concentrations (Cmax) are typically achieved at approximately 5 hours post-dose. Cmax and the area under the plasma concentration-time curve (AUC) increased proportionally up to the highest doses studied [700 mg single-dose (1.75 times the 400 mg loading dose)] [see Dosage and Administration (2.3)]. Administration of SIRTURO with a standard meal containing approximately 22 grams of fat (558 total Kcal) increased the relative bioavailability by about 2-fold compared to administration under fasted conditions. Therefore, SIRTURO should be taken with food to enhance its oral bioavailability.
Distribution
The plasma protein binding of bedaquiline is greater than 99.9%. The volume of distribution in the central compartment is estimated to be approximately 164 Liters.
Metabolism
CYP3A4 was the major CYP isoenzyme involved in vitro in the metabolism of bedaquiline and the formation of the N-monodesmethyl metabolite (M2), which is 4 to 6-times less active in terms of antimycobacterial potency.
Elimination
After reaching Cmax, bedaquiline concentrations decline tri-exponentially. The mean terminal elimination half-life of bedaquiline and the N-monodesmethyl metabolite (M2) is approximately 5.5 months. This long terminal elimination phase likely reflects slow release of bedaquiline and M2 from peripheral tissues.
Excretion
Based on preclinical studies, bedaquiline is mainly eliminated in feces. The urinary excretion of unchanged bedaquiline was less than or equal to 0.001% of the dose in clinical studies, indicating that renal clearance of unchanged drug is insignificant.
Specific Populations
Hepatic Impairment: After single-dose administration of 400 mg SIRTURO to 8 patients with moderate hepatic impairment (Child-Pugh B), mean exposure to bedaquiline and M2 (AUC672h) was approximately 20% lower compared to healthy subjects. SIRTURO has not been studied in patients with severe hepatic impairment. [See Warnings and Precautions (5.3) and Use in Specific Populations (8.6)].
Renal Impairment: SIRTURO has mainly been studied in patients with normal renal function. Renal excretion of unchanged bedaquiline is not substantial (less than or equal to 0.001%).
In a population pharmacokinetic analysis of MDR-TB patients treated with SIRTURO 200 mg three times per week, creatinine clearance was not found to influence the pharmacokinetic parameters of bedaquiline. It is therefore not expected that mild or moderate renal impairment will have a clinically relevant effect on the exposure to bedaquiline. However, in patients with severe renal impairment or end-stage renal disease requiring hemodialysis or peritoneal dialysis bedaquiline concentrations may be increased due to alteration of drug absorption, distribution, and metabolism secondary to renal dysfunction. As bedaquiline is highly bound to plasma proteins, it is unlikely that it will be significantly removed from plasma by hemodialysis or peritoneal dialysis [see Use in Specific Populations (8.7)].
Sex: In a population pharmacokinetic analysis of MDR-TB patients treated with SIRTURO no clinically relevant difference in exposure between men and women were observed.
Race/Ethnicity: In a population pharmacokinetic analysis of MDR-TB patients treated with SIRTURO, systemic exposure (AUC) to bedaquiline was found to be 34% lower in Black patients than in patients from other race categories. This lower exposure was not considered to be clinically relevant as no clear relationship between exposure to bedaquiline and response has been observed in clinical trials of MDR-TB. Furthermore, response rates were comparable in patients of different race categories that completed 24 weeks of bedaquiline treatment.
HIV Co-infection: There are limited data on the use of SIRTURO in HIV co-infected patients [see Drug Interactions (7)].
Geriatric Population: There are limited data on the use of SIRTURO in tuberculosis patients 65 years and older.
In a population pharmacokinetic analysis of MDR-TB patients treated with SIRTURO, age was not found to influence the pharmacokinetics of bedaquiline.
Pediatric Population: The pharmacokinetics of SIRTURO in pediatric patients have not been evaluated.

In vitro, bedaquiline does not significantly inhibit the activity of the following CYP450 enzymes that were tested: CYP1A2, CYP2A6, CYP2C8/9/10, CYP2C19, CYP2D6, CYP2E1, CYP3A4, CYP3A4/5 and CYP4A, and it does not induce CYP1A2, CYP2C9, CYP2C19, or CYP3A4 activities.
Bedaquiline is an in vitro substrate of CYP3A4, and because of this, the following clinical drug interaction studies were performed.
Ketoconazole: Co-administration of multiple-dose bedaquiline (400 mg once daily for 14 days) and multiple-dose ketoconazole (once daily 400 mg for 4 days) in healthy subjects increased the AUC24h, Cmax and Cmin of bedaquiline by 22% [90% CI (12; 32)], 9% [90% CI (-2, 21)] and 33% [90% CI (24, 43)] respectively [see Drug Interactions (7.1) and (7.4)].
Rifampin: In a drug interaction study of single-dose 300 mg bedaquiline and multiple-dose rifampin (once daily 600 mg for 21 days) in healthy subjects, the exposure (AUC) to bedaquiline was reduced by 52% [90% CI (-57; -46)] [see Drug Interactions (7.1)].
Antimicrobial agents: The combination of multiple-dose bedaquiline 400 mg once daily with multiple-dose isoniazid/pyrazinamide (300 mg/2000 mg once daily) in healthy subjects did not result in clinically relevant changes in the exposure (AUC) to bedaquiline, isoniazid or pyrazinamide [see Drug Interactions (7.2)].
In a placebo-controlled study in patients with MDR-TB, no major impact of co-administration of bedaquiline on the pharmacokinetics of ethambutol, kanamycin, pyrazinamide, ofloxacin or cycloserine was observed.
Lopinavir/ritonavir: In a drug interaction study in healthy volunteers of single-dose bedaquiline (400 mg) and multiple-dose lopinavir (400 mg)/ritonavir (100 mg) given twice daily for 24 days, the mean AUC of bedaquiline was increased by 22% [90% CI (11; 34)] while the mean Cmax was not substantially affected [see Drug Interactions (7.3)].
Nevirapine: Co-administration of multiple-dose nevirapine 200 mg twice daily for 4 weeks in HIV-infected patients with a single 400 mg dose of bedaquiline did not result in clinically relevant changes in the exposure to bedaquiline [see Drug Interactions (7.3)].
Efavirenz: Co-administration of a single dose of bedaquiline 400 mg and efavirenz 600 mg daily for 27 days to healthy volunteers resulted in approximately a 20% decrease in the AUCinf of bedaquiline; the Cmax of bedaquiline was not altered. The AUC and Cmax of the primary metabolite of bedaquiline (M2) were increased by 70% and 80%, respectively. The effect of efavirenz on the pharmacokinetics of bedaquiline and M2 following steady-state administration of bedaquiline has not been evaluated [see Drug Interactions (7.3)].
12.4 Microbiology
Mechanism of Action
SIRTURO is a diarylquinoline antimycobacterial drug that inhibits mycobacterial ATP (adenosine 5'-triphosphate) synthase, by binding to subunit c of the enzyme that is essential for the generation of energy in M. tuberculosis.
Drug Resistance
A potential for development of resistance to bedaquiline in M. tuberculosis exists. Modification of the atpE target gene, and/or upregulation of the MmpS5-MmpL5 efflux pump have been associated with increased bedaquiline MIC values in isolates of M. tuberculosis. Target-based mutations generated in preclinical studies lead to 8- to 133-fold increases in bedaquiline MIC, resulting in MICs ranging from 0.25 to 4.0 micrograms per mL. Efflux-based mutations have been seen in preclinical and clinical isolates. These lead to 2- to 8-fold increases in bedaquiline MICs, resulting in bedaquiline MICs ranging from 0.25 to 0.50 micrograms per mL.
Cross-Resistance
M. tuberculosis isolates from a clinical study in patients with MDR-TB that developed at least 4-fold increase in bedaquiline MIC were associated with mutations in Rv0678 gene that lead to upregulation of the MmpS5-MmpL5 efflux pump. Isolates with these efflux-based mutations are less susceptible to clofazimine.
Activity In Vitro and in Clinical Infections
SIRTURO has been shown to be active in vitro and in clinical infections against most isolates of M. tuberculosis [see Indications and Usage (1) and Clinical Studies (14)].
Susceptibility Test Methods
In vitro susceptibility tests should be performed according to published methods1,2,3, and a MIC value should be reported. However, no correlation was seen between the culture conversion rates at Week 24 and baseline MICs in clinical studies (Table 2) and susceptibility test interpretive criteria for bedaquiline cannot be established at this time. A specialist in drug-resistant TB should be consulted in evaluating therapeutic options.
When susceptibility testing is performed by 7H9 broth microdilution or agar methods, a range of concentrations from 0.008 microgram per mL to 2.0 micrograms per mL should be assessed. The minimum inhibitory concentration (MIC) should be determined as the lowest concentration of bedaquiline that results in complete inhibition of growth by either agar or broth methods. All assays should be performed in polystyrene plates or tubes. Löwenstein-Jensen (LJ) medium should not be used for the susceptibility testing. Bedaquiline working solution should be prepared in dimethylsulfoxide (DMSO). An inoculum of approximately 105 colony forming units/mL should be used for both liquid and solid media.
The bedaquiline agar (left) and resazurin microtiter assay (REMA; a 7H9 broth microdilution to which resazurin, a bacterial growth indicator, was added) (right) MIC distributions against clinical isolates resistant to isoniazid and rifampin from Studies 1, 2, and 3 are provided below.

Nineteen patients in the efficacy population of study 3 had bedaquiline susceptibility testing results of paired (baseline and post-baseline, all of which were at Week 24 or later) genotypically identical isolates. Twelve of the 19 had a post-baseline ≥4-fold increase in bedaquiline MIC. Whole genome sequencing of 9 of these 12 post-baseline isolates was done and no mutations were found in the ATP synthase operon. All 9 were found to have a mutation in Rv0678. Eleven of the twelve (11/12) increases in bedaquiline MIC were seen in patients with pre-XDR-TB or with XDR-TB. Pre-XDR-TB is defined as MDR-TB isolates resistant to either a fluoroquinolone or a second line injectable drug, and XDR-TB as MDR-TB isolates resistant to both a fluoroquinolone and a second line injectable drug. Based on available data, response rate (culture conversion at week 120 endpoint) was similar in subjects with ≥4-fold increases in bedaquiline MIC (5/12) and subjects with < 4-fold increases (3/7).
Quality Control
Susceptibility test procedures require the use of laboratory controls to monitor and ensure the accuracy and precision of testing. Assays using standard bedaquiline powder should provide the following range of MIC values shown in Table 3.

13 NON-CLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, and Impairment of Fertility
Bedaquiline was not carcinogenic in rats up to the maximum tolerated dose of 10 mg/kg/day. Exposures at this dose in rats (AUCs) were within 1-fold to 2-fold of those observed in subjects in the Phase 2 clinical trials.
No mutagenic or clastogenic effects were detected in the in vitro non-mammalian reverse mutation (Ames) test, in vitro mammalian (mouse lymphoma) forward mutation assay and an in vivo mouse bone marrow micronucleus assay.
SIRTURO had no effects on fertility when evaluated in male and female rats. No relevant drug-related effects on developmental toxicity parameters were observed in rats and rabbits. The corresponding plasma exposure (AUC) was 2-fold higher in rats and lower for rabbits compared to humans. There was no effect of maternal treatment with bedaquiline at any dose level on sexual maturation, behavioral development, mating performance, fertility or reproductive capacity of the F1 generation animals. Body weight decreases in pups were noted in high dose groups during the lactation period after exposure to bedaquiline via milk and were not a consequence of in utero exposure. Concentrations of bedaquiline in milk were 6-fold to 12-fold higher that the maximum concentration observed in maternal plasma.
13.2 Animal Toxicology and/or Pharmacology
Bedaquiline is a cationic, amphiphilic drug that induced phospholipidosis (at almost all doses, even after very short exposures) in drug-treated animals, mainly in cells of the monocytic phagocytic system (MPS). All species tested showed drug-related increases in pigment-laden and/or foamy macrophages, mostly in the lymph nodes, spleen, lungs, liver, stomach, skeletal muscle, pancreas and/or uterus. After treatment ended, these findings were slowly reversible. Muscle degeneration was observed in several species at the highest doses tested. For example the diaphragm, esophagus, quadriceps and tongue of rats were affected after 26 weeks of treatment at doses similar to clinical exposures based on AUC comparisons. These findings were not seen after a 12-week, treatment-free, recovery period and were not present in rats given the same dose biweekly. Degeneration of the fundic mucosa of the stomach, hepatocellular hypertrophy and pancreatitis were also seen.
14 CLINICAL STUDIES
A placebo-controlled, double-blind, randomized trial (Study 1) was conducted in patients with newly diagnosed sputum smear-positive MDR pulmonary M. tuberculosis. All patients received a combination of five other antimycobacterial drugs used to treat MDR-TB (i.e., ethionamide, kanamycin, pyrazinamide, ofloxacin, and cycloserine/terizidone or available alternative) for a total duration of 18–24 months or at least 12 months after the first confirmed negative culture. In addition to this regimen, patients were randomized to receive 24 weeks of treatment with SIRTURO 400 mg once daily for the first 2 weeks followed by 200 mg 3 times per week for 22 weeks or matching placebo for the same duration. Overall, 79 patients were randomized to the SIRTURO arm and 81 to the placebo arm. A final evaluation was conducted at Week 120.
Sixty-seven patients randomized to SIRTURO and 66 patients randomized to placebo had confirmed MDR-TB, based on susceptibility tests (taken prior to randomization) or medical history if no susceptibility results were available, and were included in the efficacy analyses. Demographics were as follows: 63% of the study population was male, with a median age of 34 years, 35% were Black, and 15% were HIV-positive (median CD4 cell count 468 cells/µL). Most patients had cavitation in one lung (62%); and 18% of patients had cavitation in both lungs.
Time to sputum culture conversion was defined as the interval in days between the first dose of study drug and the date of the first of two consecutive negative sputum cultures collected at least 25 days apart during treatment. In this trial, the SIRTURO treatment group had a decreased time to culture conversion and improved culture conversion rates compared to the placebo treatment group at Week 24. Median time to culture conversion was 83 days for the SIRTURO treatment group compared to 125 days for the placebo treatment group. Table 4 shows the proportion of patients with sputum culture conversion at Week 24 and Week 120.

A patient's reason for treatment failure was counted only in the first row for which a patient qualifies.
Patients received 24 weeks of SIRTURO or placebo for the first 24 weeks and received a combination of other antimycobacterial drugs for up to 96 weeks.
Study 2 was a smaller placebo controlled study designed similarly to Study 1 except that SIRTURO or placebo was given for only 8 weeks instead of 24 weeks. Patients were randomized to either SIRTURO and other drugs used to treat MDR-TB (SIRTURO treatment group) (n=23) or placebo and other drugs used to treat MDR-TB (placebo treatment group) (n=24). Twenty-one patients randomized to the SIRTURO treatment group and 23 patients randomized to the placebo treatment group had confirmed MDR-TB based on subjects' baseline M. tuberculosis isolate obtained prior to randomization. The SIRTURO treatment group had a decreased time to culture conversion and improved culture conversion rates compared to the placebo treatment group at Week 8. At Weeks 8 and 24, the differences in culture conversion proportions were 38.9% (95% CI: [12.3%, 63.1%] and p-value: 0.004), 15.7% (95% CI: [-11.9%, 41.9%] and p-value: 0.32), respectively.
Study 3 was a Phase 2b, uncontrolled study to evaluate the safety, tolerability, and efficacy of SIRTURO as part of an individualized MDR-TB treatment regimen in 233 patients with sputum smear positive (within 6 months prior to screening) pulmonary MDR-TB. Patients received SIRTURO for 24 weeks in combination with antibacterial drugs. Upon completion of the 24 week treatment with SIRTURO, all patients continued to receive their background regimen in accordance with national TB program (NTP) treatment guidelines. A final evaluation was conducted at Week 120. Treatment responses to SIRTURO at week 120 were generally consistent with those from Study 1.

强生新型结核病药物Sirturo获欧盟上市批准
强生旗下Sirturo在欧洲获得批准,成为几十年来进入欧洲市场的新类型结核病 (TB)治疗药物之一。欧盟已授予Sirturo(bedaquiline)上市许可,做为肺多重耐药(MDR)TB合并治疗方案的一部分,该病症属孤儿适应症,在欧洲影响大约万分之二的人口。
这次的批准基于一项2期临床试验,强生下属子公司杨森制药正在开展一项 3期临床试验,以确证这款药物的风险和收益。Sirturo于2012年年底在美国获得批准,它是TB治疗的一项重要科学进展,因为这款药物是首款抑制分枝杆菌三磷酸腺苷合酶的药物,分枝杆菌三磷酸腺苷合酶是结核菌能量产生所必需的一种酶。
“MDR-TB与高死亡率相关,对公共健康造成明显威胁,作为感染了耐药菌株的个人,通常不能获得充分的治疗,并将他们的感染进行传播,”阿姆斯特丹大学热带医学和旅行医学中心主管Martin Grobusch教授评论说。Bedaquiline的批准“是应对这种快速增长疾病迈出的关键一步,加快了患者获取急需的治疗药物,”他补充说。
治疗多药耐药结核病完全新颖的药物一直寥寥无几,去年欧洲批准了一连串的新药,有日本大冢的Deltyba(delamanid),这款药物去年9月获得有条件批准,另外还有Pharma SA的对氨水杨酸。
近年来,TB对至少包括异烟肼和利福平在内的一线治疗药物耐药的负担因缺乏新的治疗选择而迅速增长,异烟肼和利福平是两款重要的抗结核病治疗药物。
关于Sirturo(bedaquiline 中文译名 富马酸贝达喹啉)
Sirturo(bedaquiline 中文译名 富马酸贝达喹啉片)作为杨森公司的重大科研成果,富马酸贝达喹啉片是近几十年来获得批准的首个具有创新作用机制的抗结核病新药。它具有一种独特的作用机制,能够抑制结核分枝杆菌ATP合成酶,该酶是结核分枝杆菌能量生成所必需的。2012年,美国食品药品管理局加速审批通过了贝达喹啉,欧盟也有条件地批准了该药物。通过俄罗斯联邦和独联体国家的合作伙伴JSC Pharmstandard,富马酸贝达喹啉片在俄罗斯联邦成功注册。此外,富马酸贝达喹啉片还在中国、亚美尼亚、中国香港特别行政区、印度、新西兰、秘鲁、菲律宾、南非、韩国、台湾地区、土库曼斯坦、乌兹别克斯坦获得了批准,在孟加拉国、布隆迪、哥伦比亚、加纳、印度尼西亚、肯尼亚、墨西哥、卢旺达、坦桑尼亚、泰国、土耳其、乌干达和越南向监管部门提交了审批申请,通过合作伙伴Pharmstandard在摩尔多瓦向监管部门提交了附加申请。
