Repotrectinib

12.1 Mechanism of Action Repotrectinib is an inhibitor of proto-oncogene tyrosine-protein kinase ROS1 (ROS1) and of the tropomyosin receptor tyrosine kinases (TRKs) TRKA, TRKB, and TRKC. Fusion proteins that include ROS1 or TRK domains can drive tumorigenic potential through hyperactivation of downstream signaling pathways leading to unconstrained cell proliferation. Repotrectinib exhibited anti-tumor activity in cultured cells expressing ROS1 fusions and mutations including SDC4-ROS1, SDC4-ROS1 G2032R , CD74-ROS1, CD74-ROS1 G2032R , CD74-ROS1 D2033N , and CD74-ROS1 L2026M . Repotrectinib also inhibited cell proliferation in cultured cells expressing NTRK fusions and mutations including LMNA-TRKA, LMNA-TRKA G595R , EVT6-TRKB G639R , and ETV6-TRKC G623R .

1 INDICATIONS AND USAGE AUGTYRO is a kinase inhibitor indicated for the treatment of • adult patients with locally advanced or metastatic ROS1- positive non-small cell lung cancer (NSCLC). ( 1.1 ) • adult and pediatric patients 12 years of age and older with solid tumors that: • have a neurotrophic tyrosine receptor kinase ( NTRK ) gene fusion and • are locally advanced or metastatic or where surgical resection is likely to result in severe morbidity. • have progressed following treatment or have no satisfactory alternative therapy. This indication is approved under accelerated approval based on overall response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in the confirmatory trials. ( 1.2 ) 1.1 ROS1 -Positive Non-Small Cell Lung Cancer AUGTYRO is indicated for the treatment of adult patients with locally advanced or metastatic ROS1 -positive non-small cell lung cancer (NSCLC) [see Dosage and Administration (2.1) ] . 1.2 NTRK Gene Fusion-Positive Solid Tumors AUGTYRO is indicated for the treatment of adult and pediatric patients 12 years of age and older with solid tumors that: • have a neurotrophic tyrosine receptor kinase ( NTRK ) gene fusion [see Dosage and Administration ( 2.1 )] , • are locally advanced or metastatic or where surgical resection is likely to result in severe morbidity, and • have progressed following treatment or have no satisfactory alternative therapy. This indication is approved under accelerated approval based on overall response rate and duration of response [see Clinical Studies ( 14.2 )] . Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).

The pooled safety population described in WARNINGS AND PRECAUTIONS and below reflects exposure to AUGTYRO in 426 patients with ROS1 -positive NSCLC (n=320), NTRK1/2/3 -positive solid tumors (n=104), or other solid tumors (n=2) in TRIDENT-1. Patients received AUGTYRO at a dose of 160 mg orally once daily for the first 14 days, then increased to 160 mg orally twice daily until disease progression or unacceptable toxicity [see Clinical Studies ( 14.1 ), ( 14.2 )] . Eligible patients had an ECOG status of ≤1. Patients with a history of ILD, drug-related pneumonitis, significant, uncontrolled, active cardiovascular disease, or prolonged QTc interval were excluded from enrollment in this trial. Forty-eight percent of patients were exposed to AUGTYRO for at least 6 months, and 28% were exposed for greater than 1 year. The median age of patients who received AUGTYRO was 57 years (range: 18 to 93); 59% female; 43% White, 47% Asian, 2.8% Black, 0.5% Native Hawaiian or Other Pacific Islander, 0.5% American Indian or Alaska Native, 6.1% race not reported or other, and 0.7% unknown. Serious adverse reactions occurred in 35% of patients who received AUGTYRO. Serious adverse reactions in ≥2% of patients included pneumonia (6.3%), dyspnea (3.1%), pleural effusion (2.8%), and hypoxia (2.6%). Fatal adverse reactions occurred in 3.5% of patients who received AUGTYRO, including pneumonia, pneumonia aspiration, cardiac arrest, sudden cardiac death, cardiac failure, hypoxia, dyspnea, respiratory failure, tremor, and disseminated intravascular coagulation. Permanent discontinuation of AUGTYRO due to an adverse reaction occurred in 7% of patients. There were no specific adverse reactions that accounted for ≥1% of permanent discontinuations. Dosage interruptions of AUGTYRO due to an adverse reaction occurred in 50% of patients. Adverse reactions that required dosage interruption in ≥2% of patients were dizziness, dyspnea, muscular weakness, ataxia, pneumonia, peripheral neuropathy, anemia, and vomiting. Dose reductions of AUGTYRO due to an adverse reaction occurred in 38% of patients. Adverse reactions that required dosage reductions in ≥2% of patients included dizziness, ataxia, muscular weakness, peripheral neuropathy, and cognitive impairment. The most common (≥20%) adverse reactions that occurred in patients receiving AUGTYRO were dizziness, dysgeusia, peripheral neuropathy, constipation, dyspnea, fatigue, ataxia, cognitive impairment, muscular weakness and nausea.

7 DRUG INTERACTIONS • Strong and Moderate CYP3A Inhibitors : Avoid concomitant use. ( 7.1 ) • P-gp inhibitors : Avoid concomitant use. ( 7.1 ) • Strong and Moderate CYP3A Inducers : Avoid concomitant use. ( 7.1 ) • Certain CYP3A Substrates : Avoid concomitant use with CYP3A substrates, where minimal concentration changes can cause reduced efficacy. ( 7.2 ) • Hormonal contraceptives : Avoid concomitant use. ( 7.2 ) 7.1 Effects of Other Drugs on AUGTYRO Strong and Moderate CYP3A Inhibitors Avoid concomitant use with strong or moderate CYP3A inhibitors. Concomitant use of AUGTYRO with a strong or a moderate CYP3A inhibitor may increase repotrectinib exposure, which may increase the incidence and severity of adverse reactions of AUGTYRO. Discontinue CYP3A inhibitors for 3 to 5 elimination half-lives of the CYP3A inhibitor prior to initiating AUGTYRO [see Clinical Pharmacology (12.3) ] . P-gp Inhibitors Avoid concomitant use with P-gp inhibitors. Concomitant use of AUGTYRO with a P-gp inhibitor may increase repotrectinib exposure, which may increase the incidence and severity of adverse reactions of AUGTYRO [see Clinical Pharmacology (12.3) ] . Strong and Moderate CYP3A Inducers Avoid concomitant use with strong or moderate CYP3A inducers. Concomitant use of AUGTYRO with a strong or moderate CYP3A inducer may decrease repotrectinib plasma concentrations, which may decrease efficacy of AUGTYRO [see Clinical Pharmacology (12.3) ] . 7.2 Effects of AUGTYRO on Other Drugs Certain CYP3A4 Substrates Avoid concomitant use unless otherwise recommended in the Prescribing Information for CYP3A substrates, where minimal concentration changes can cause reduced efficacy. If concomitant use is unavoidable, increase the CYP3A4 substrate dosage in accordance with approved product labeling. Repotrectinib is a CYP3A4 inducer. Concomitant use of repotrectinib decreases the concentration of CYP3A4 substrates [see Clinical Pharmacology (12.3) ] , which can reduce the efficacy of these substrates. Contraceptives Repotrectinib is a CYP3A4 inducer, which can decrease progestin or estrogen exposure to an extent that could reduce the effectiveness of hormonal contraceptives. Avoid concomitant use of AUGTYRO with hormonal contraceptives [see Use in Specific Populations (8.1 , 8.3) ] . Advise females of reproductive potential to use an effective nonhormonal contraceptive [see Use in Specific Populations (8.1 , 8.3) ] .
