Augtyro is the only FDA-approved treatment option for NTRK-positive tumors studied in both TKI-na ï ve and TKI-pretreated patients across solid tumors , demonstrating clinically meaningful response rates in the TRIDENT-1 trial1
This accelerated approval marks the second indication for Augtyro in the U.S.1
PRINCETON, N.J.–(BUSINESS WIRE)– Bristol Myers Squibb (NYSE: BMY) today announced that the U.S. Food and Drug Administration (FDA) has granted accelerated approval of Augtyro™ (repotrectinib) 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, 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.1 The approval is based on results from the Phase 1/2 TRIDENT-1 study, which evaluated Augtyro in adult patients with NTRK-positive solid tumors.1 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
“NTRK fusion-positive tumors can present challenges in the clinical setting, which is why it is important that we have additional treatment options for these patients,” said Alexander Drilon, MD, TRIDENT-1 global trial lead and Chief of the Early Drug Development Service at Memorial Sloan Kettering Cancer Center.2,3 “The FDA approval of repotrectinib adds an important tool to our toolbox, offering oncologists a next-generation TKI that can be used across a broad range of NTRK fusion-positive solid tumors for both TKI-naïve and TKI-pretreated patients.”1
The TRIDENT-1 trial included both TKI-naïve (n=40) and TKI-pretreated (n=48) patients with NTRK-positive locally advanced/metastatic solid tumors collectively representing 15 different types of cancer.1 In TKI-naïve patients, with a median follow up of 17.8 months, 58% (95% CI: 41 to 73) had a confirmed objective response rate (cORR); of those, 43% experienced partial responses (PR) and 15% had complete responses (CR).1,4 Of the TKI-naïve responding patients, 83% were still in response at one year with Augtyro. The median duration of response (mDOR) was not yet reached. In TKI-pretreated patients, with a median follow up of 20.1 months, the cORR was 50% (95% CI: 35 to 65); of those, 50% experienced PR and no patients achieved CR.1,4 Additionally, 42% of TKI-pretreated responding patients were still in response at one year with Augtyro.1 The mDOR was 9.9 months (95% CI: 7.4 to 13.0).1 Among those who had measurable central nervous system (CNS) metastases at baseline, intracranial response was observed in 2 out of 2 TKI-naïve patients and in 3 out of 3 TKI-pretreated patients.1
Augtyro is associated with the following Warnings & Precautions: central nervous system (CNS) effects, interstitial lung disease (ILD)/pneumonitis, hepatotoxicity, myalgia with creatine phosphokinase elevation, hyperuricemia, skeletal fractures, and embryo-fetal toxicity.1 Please see Important Safety Information below.
“Today’s FDA approval of Augtyro for patients with NTRK-positive tumors adds to its indication in ROS1-positive NSCLC, showing its clinical value for more people across multiple genetic markers,” said Nick Botwood, senior vice president of Medical Oncology at Bristol Myers Squibb.1 “Previously, there was not an FDA approved treatment option for NTRK-positive cancers that was studied in both TKI-naïve and TKI-pretreated patients across solid tumors. This milestone helps address this area of unmet need and builds on Bristol Myers Squibb’s longstanding legacy of bringing innovations to individuals who are facing cancer and urgently seeking new treatment options.”
“Cancer can be frightening regardless of the type, but having a rare gene fusion driving it can be especially stressful and isolating,” said Susan Spinosa, president and patient co-founder of NTRKers, a patient advocacy group. “It’s exciting to know that there’s a new targeted therapy option for patients with NTRK-positive gene fusions, as this may offer hope to patients and their loved ones navigating this difficult journey.”
Based on clinical and pharmacokinetic data, the recommended dose for Augtyro for pediatric patients aged 12 years and older is the same as for adults, 160 mg orally once daily for 14 days followed by 160 mg twice daily until disease progression or unacceptable toxicity.1 The safety and effectiveness of Augtyro have not been established in pediatric patients younger than 12 years of age with solid tumors who have an NTRK gene fusion.1 This is the second indication for Augtyro in the U.S., following its full approval for the treatment of adult patients with locally advanced or metastatic ROS1-positive NSCLC in November 2023.1

About TRIDENT-1
TRIDENT-1 is a global, multicenter, single-arm, open-label, multi-cohort Phase 1/2 clinical trial evaluating the safety, tolerability, pharmacokinetics and anti-tumor activity of Augtyro in patients with locally advanced or metastatic neurotrophic tyrosine receptor kinase (NTRK) gene fusion-positive (NTRK1/2/3) solid tumors.1,5 The trial excludes patients with symptomatic brain metastases, among other exclusion criteria.1 Phase 1 of the trial included the dose escalation that determined the recommended Phase 2 dose.5
Phase 2 of the trial in NTRK-positive locally advanced/metastatic solid tumor cohorts has a primary endpoint of objective response rate (ORR) as assessed by Blinded Independent Central Review (BICR).5 Among others, key secondary endpoints include duration of response (DOR) according to Response Evaluation Criteria in Solid Tumors (RECIST v1.1) as assessed by BICR, and intracranial response in patients with measurable brain metastases.5
Select Safety Profile from TRIDENT-1
The safety profile for Augtyro was evaluated in 426 patients who received Augtyro in the TRIDENT-1 pivotal trial.1 Permanent discontinuation of Augtyro due to an adverse reaction occurred in 7% of patients.1 There were no specific adverse reactions that accounted for ≥1% of permanent discontinuations. Augtyro dosage was interrupted due to an adverse reaction in 50% of patients, and dose reductions due to an adverse reaction occurred in 38% of patients.1 Serious adverse reactions occurred in 35% of patients who received Augtyro. 1 Serious adverse reactions in ≥2% of patients included pneumonia (6.3%), dyspnea (3.1%), pleural effusion (2.8%) and hypoxia (2.6%).1 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.1 The most common (≥20%) adverse reactions were dizziness (65%), dysgeusia (54%), peripheral neuropathy (49%), constipation (38%), dyspnea (30%), fatigue (30%), ataxia (28%), cognitive impairment (25%), muscular weakness (20%) and nausea (20%).1 Grade 3 dizziness occurred in 2.8% of patients.1
About NTRK-Positive Solid Tumors
Neurotrophic tropomyosin receptor kinase (NTRK) are a family of receptors involved in neural development.6 An NTRK gene fusion is an alteration that occurs when a piece of the chromosome containing the NTRK gene breaks off and joins with a gene on another chromosome.7 These fusions lead to abnormal proteins, which may cause cancer cells to grow.7 While NTRK gene fusions are rare in patients with solid tumors, testing for NTRK gene fusions allows for the identification of patients who may benefit from TRK inhibitor therapy.8,9,10,11

Advise patients not to drive or use machines if they are experiencing CNS adverse reactions. Withhold and then resume at same or reduced dose upon improvement, or permanently discontinue AUGTYRO based on severity.
Interstitial Lung Disease (ILD)/Pneumonitis
Among the 426 patients treated with AUGTYRO, ILD/pneumonitis (pneumonitis [2.8%] and ILD [0.2%]) occurred in 3.1%; Grade 3 ILD/pneumonitis occurred in 1.2%. The median time to onset was 45 days (19 days to 0.9 years). Dose interruption was required in 1.4% of patients, 0.5% required dose reduction, and 1.1% permanently discontinued AUGTYRO due to ILD/pneumonitis.
Monitor patients for new or worsening pulmonary symptoms indicative of ILD/pneumonitis. Immediately withhold AUGTYRO in patients with suspected ILD/pneumonitis and permanently discontinue AUGTYRO if ILD/pneumonitis is confirmed.
Hepatotoxicity
Among the 426 patients treated with AUGTYRO, increased alanine transaminase (ALT) occurred in 38%, increased aspartate aminotransferase (AST) occurred in 41%, including Grade 3 or 4 increased ALT in 3.3% and increased AST in 2.9%. The median time to onset of increased ALT or AST was 15 days (range: 1 day to 1.9 years). Increased ALT or AST leading to dose interruptions or reductions occurred in 2.8% and 1.2% of patients, respectively. Hyperbilirubinemia leading to dose interruptions occurred in 0.5%.
Monitor liver function tests, including ALT, AST and bilirubin, every 2 weeks during the first month of treatment, then monthly thereafter and then as clinically indicated. Withhold and then resume at same or reduced dose upon improvement or permanently discontinue AUGTYRO based on the severity.
Myalgia with Creatine Phosphokinase (CPK) Elevation
AUGTYRO can cause myalgia with or without creatine phosphokinase (CPK) elevation. Among the 426 patients treated with AUGTYRO, myalgia occurred in 13% of patients, with Grade 3 in 0.7%. Median time to onset of myalgia was 19 days (range: 1 day to 2 years). Concurrent increased CPK within a 7-day window was observed in 3.7% of patients. AUGTYRO was interrupted in one patient with myalgia and concurrent CPK elevation.
Advise patients to report any unexplained muscle pain, tenderness, or weakness. Monitor serum CPK levels during AUGTYRO treatment and monitor CPK levels every 2 weeks during the first month of treatment and as needed in patients reporting unexplained muscle pain, tenderness, or weakness. Initiate supportive care as clinically indicated. Based on severity, withhold and then resume AUGTYRO at same or reduced dose upon improvement.
Hyperuricemia
Among the 426 patients treated with AUGTYRO, 21 patients (5%) experienced hyperuricemia reported as an adverse reaction, 0.7% experienced Grade 3 or 4 hyperuricemia. One patient without pre-existing gout required urate-lowering medication.
Monitor serum uric acid levels prior to initiating AUGTYRO and periodically during treatment. Initiate treatment with urate-lowering medications as clinically indicated. Withhold and then resume at same or reduced dose upon improvement, or permanently discontinue AUGTYRO based on severity.
Skeletal Fractures
Among 426 adult patients who received AUGTYRO, fractures occurred in 2.3%. Fractures involved the ribs (0.5%), feet (0.5%), spine (0.2%), acetabulum (0.2%), sternum (0.2%), and ankles (0.2%). Some fractures occurred at sites of disease and prior radiation therapy. The median time to fracture was 71 days (range: 31 days to 1.4 years). AUGTYRO was interrupted in 0.3% of patients.
Of 26 evaluable patients in an ongoing open-label study in pediatric patients, fractures occurred in one 12-year-old patient (ankle/foot) and one 10-year-old patient (stress fracture). AUGTYRO was interrupted in both patients. AUGTYRO is not approved for use in pediatric patients less than 12 years of age.
Promptly evaluate patients with signs or symptoms (e.g., pain, changes in mobility, deformity) of fractures. There are no data on the effects of AUGTYRO on healing of known fractures and risk of future fractures.
Embryo-Fetal Toxicity
Based on literature reports in humans with congenital mutations leading to changes in tropomyosin receptor tyrosine kinase (TRK) signaling, findings from animal studies, and its mechanism of action, AUGTYRO can cause fetal harm when administered to a pregnant woman.
Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective non-hormonal contraception during treatment with AUGTYRO and for 2 months following the last dose, since AUGTYRO can render some hormonal contraceptives ineffective.
Advise male patients with female partners of reproductive potential to use effective contraception during treatment with AUGTYRO and for 4 months after the last dose.
Adverse Reactions
The safety of AUGTYRO was evaluated in 426 patients in TRIDENT-1. The most common adverse reactions (≥20%) were dizziness, dysgeusia, peripheral neuropathy, constipation, dyspnea, fatigue, ataxia, cognitive impairment, muscular weakness, and nausea.
Drug Interactions
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.
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.
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.
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, 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. Advise females of childbearing potential to use an effective nonhormonal contraceptive.
