Uses
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.
Dosage
2 DOSAGE AND ADMINISTRATION • Select patients for the treatment of locally advanced or metastatic NSCLC based on the presence of ROS1 rearrangement(s) in tumor specimens. ( 2.1 ) • Select patients for treatment of locally advanced or metastatic solid tumors based on the presence of an NTRK gene fusion. ( 2.1 ) • Recommended Dosage : 160 mg orally once daily for 14 days, then increase to 160 mg twice daily, with or without food. ( 2.4 ) 2.1 Patient Selection NSCLC Select patients for the treatment of locally advanced or metastatic NSCLC with AUGTYRO based on the presence of ROS1 rearrangement(s) in tumor specimens [see Clinical Studies (14.1) ] . An FDA-approved test to detect ROS1 rearrangements for selecting patients for treatment with AUGTYRO is not currently available.
Side Effects
6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: • Central Nervous System Adverse Reactions [see Warnings and Precautions (5.1) ] • Interstitial Lung Disease (ILD)/Pneumonitis [see Warnings and Precautions (5.2) ] • Hepatotoxicity [see Warnings and Precautions (5.3) ] • Myalgia with Creatine Phosphokinase Elevation [see Warnings and Precautions (5.4) ] • Hyperuricemia [see Warnings and Precautions (5.5) ] • Skeletal Fractures [see Warnings and Precautions (5.6) ] • Embryo-Fetal Toxicity [see Warnings and Precautions (5.7) ] The most common adverse reactions (≥20%) were dizziness, dysgeusia, peripheral neuropathy, constipation, dyspnea, fatigue, ataxia, cognitive impairment, muscular weakness, and nausea.
Interactions
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.
Warnings
5 WARNINGS AND PRECAUTIONS • Central Nervous System (CNS) Effects: Can cause CNS adverse reactions including dizziness, ataxia, and cognitive impairment. Withhold and then resume at same or reduced dose upon improvement, or permanently discontinue AUGTYRO based on severity. ( 5.1 ) • Interstitial Lung Disease (ILD)/Pneumonitis: Monitor patients for new or worsening pulmonary symptoms indicative of ILD/pneumonitis. Immediately withhold in patients with suspected ILD/pneumonitis and permanently discontinue if ILD/pneumonitis is confirmed. ( 5.2 ) • Hepatotoxicity: Monitor liver function tests every 2 weeks during the first month of treatment, and as clinically indicated thereafter. Based on severity, withhold and then resume at same or reduced dose, or permanently discontinue. 4 CONTRAINDICATIONS None. None.
Pregnancy
8.1 Pregnancy Risk Summary Based on literature reports in humans with congenital mutations leading to changes in TRK signaling, findings from animal studies, and its mechanism of action [see Clinical Pharmacology (12.1) ], AUGTYRO can cause fetal harm when administered to a pregnant woman. There are no available data on AUGTYRO use in pregnant women. Oral administration of repotrectinib to pregnant rats during the period of organogenesis resulted in fetal malformations at doses approximately 0.3 times the recommended dose of 160 mg twice daily based on BSA (see Data) .
