1 Indications And Usage

  • VITRAKVI is indicated for the treatment of adult and pediatric patients with solid tumors that: •have a neurotrophic receptor tyrosine kinase (NTRK) gene fusion without a known acquired resistance mutation, •are metastatic or where surgical resection is likely to result in severe morbidity, and •have no satisfactory alternative treatments or that have progressed following treatment.This indication is approved under accelerated approval based on overall response rate and duration of response [see Clinical Studies (14)]. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials.

2.1 Patient Selection

Select patients for treatment with VITRAKVI based on the presence of a NTRK gene fusion in tumor specimens [see Clinical Studies (14)]. An FDA-approved test for the detection of NTRK gene fusion is not currently available.

Recommended Dosage in Adult and Pediatric Patients with Body Surface Area of at Least 1.0 Meter-SquaredThe recommended dosage of VITRAKVI is 100 mg orally twice daily, with or without food, until disease progression or until unacceptable toxicity.Recommended Dosage in Pediatric Patients with Body Surface Area Less Than 1.0 Meter-SquaredThe recommended dosage of VITRAKVI is 100 mg/m2 orally twice daily, with or without food, until disease progression or until unacceptable toxicity.

2.3 Dosage Modifications For Adverse Reactions

  • For Grade 3 or 4 adverse reactions: •Withhold VITRAKVI until adverse reaction resolves or improves to baseline or Grade 1. Resume at the next dosage modification if resolution occurs within 4 weeks. •Permanently discontinue VITRAKVI if an adverse reaction does not resolve within 4 weeks.The recommended dosage modifications for VITRAKVI for adverse reactions are provided in Table 1.Table 1 Recommended Dosage Modifications for VITRAKVI for Adverse ReactionsDosageModificationAdult andPediatric Patients with BodySurface Area of at Least 1.0 m2Pediatric Patients with BodySurface Area Less Than 1.0 m2First75 mg orally twice daily75 mg/m2 orally twice dailySecond50 mg orally twice daily50 mg/m2 orally twice dailyThird100 mg orally once daily25 mg/m2 orally twice dailyPermanently discontinue VITRAKVI in patients who are unable to tolerate VITRAKVI after three dose modifications.

2.4 Dosage Modifications For Coadministration With Strong Cyp3a4 Inhibitors

Avoid coadministration of strong CYP3A4 inhibitors with VITRAKVI. If coadministration of a strong CYP3A4 inhibitor cannot be avoided, reduce the VITRAKVI dose by 50%.

4 Contraindications

None.

5.1 Neurotoxicity

Among the 176 patients who received VITRAKVI, neurologic adverse reactions of any grade occurred in 53% of patients, including Grade 3 and Grade 4 neurologic adverse reactions in 6% and 0.6% of patients, respectively [see Adverse Reactions (6.1)]. The majority (65%) of neurologic adverse reactions occurred within the first three months of treatment (range: 1 day to 2.2 years). Grade 3 neurologic adverse reactions included delirium (2%), dysarthria (1%), dizziness (1%), gait disturbance (1%), and paresthesia (1%). Grade 4 encephalopathy (0.6%) occurred in a single patient. Neurologic adverse reactions leading to dose modification included dizziness (3%), gait disturbance (1%), delirium (1%), memory impairment (1%), and tremor (1%).Advise patients and caretakers of these risks with VITRAKVI. Advise patients not to drive or operate hazardous machinery if they are experiencing neurologic adverse reactions. Withhold or permanently discontinue VITRAKVI based on the severity. If withheld, modify the VITRAKVI dosage when resumed [see Dosage and Administration (2.3)].

5.2 Hepatotoxicity

Among the 176 patients who received VITRAKVI, increased transaminases of any grade occurred in 45%, including Grade 3 increased AST or ALT in 6% of patients [see Adverse Reactions (6.1)]. One patient (0.6%) experienced Grade 4 increased ALT. The median time to onset of increased AST was 2 months (range: 1 month to 2.6 years). The median time to onset of increased ALT was 2 months (range: 1 month to 1.1 years). Increased AST and ALT leading to dose modifications occurred in 4% and 6% of patients, respectively. Increased AST or ALT led to permanent discontinuation in 2% of patients.Monitor liver tests, including ALT and AST, every 2 weeks during the first month of treatment, then monthly thereafter, and as clinically indicated. Withhold or permanently discontinue VITRAKVI based on the severity. If withheld, modify the VITRAKVI dosage when resumed [see Dosage and Administration (2.3)].

5.3 Embryo-Fetal Toxicity

Based on literature reports in human subjects with congenital mutations leading to changes in TRK signaling, findings from animal studies, and its mechanism of action, VITRAKVI can cause fetal harm when administered to a pregnant woman. Larotrectinib resulted in malformations in rats and rabbits at maternal exposures that were approximately 11- and 0.7-times, respectively, those observed at the clinical dose of 100 mg twice daily. Advise women of the potential risk to a fetus. Advise females of reproductive potential to use an effective method of contraception during treatment and for 1 week after the final dose of VITRAKVI [see Use in Specific Populations (8.1, 8.3)].

6 Adverse Reactions

  • The following clinically significant adverse reactions are described elsewhere in the labeling: •Neurotoxicity [see Warnings and Precautions (5.1)] •Hepatotoxicity [see Warnings and Precautions (5.2)]

6.1 Clinical Trial Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.Data in WARNINGS AND PRECAUTIONS and below reflects exposure to VITRAKVI in 176 patients, including 70 (40%) patients exposed for greater than 6 months and 35 (20%) patients exposed for greater than 1 year. VITRAKVI was studied in one adult dose-finding trial [LOXO-TRK-14001 (n = 70)], one pediatric dose-finding trial [SCOUT (n = 43)], and one single arm trial [NAVIGATE (n = 63)]. All patients had an unresectable or metastatic solid tumor and no satisfactory alternative treatment options or disease progression following treatment.Across these 176 patients, the median age was 51 years (range: 28 days to 82 years); 25% were 18 years or younger; 52% were male; and 72% were White, 11% were Hispanic/Latino, 8% were Black, and 3% were Asian. The most common tumors in order of decreasing frequency were soft tissue sarcoma (16%), salivary gland (11%), lung (10%), thyroid (9%), colon (8%), infantile fibrosarcoma (8%), primary central nervous system (CNS) (7%), or melanoma (5%). NTRK gene fusions were present in 60% of VITRAKVI-treated patients. Most adults (80%) received VITRAKVI 100 mg orally twice daily and 68% of pediatrics (18 years or younger) received VITRAKVI 100 mg/m2 twice daily up to a maximum dose of 100 mg twice daily. The dose ranged from 50 mg daily to 200 mg twice daily in adults and 9.6 mg/m2 twice daily to 120 mg/m2 twice daily in pediatrics [see Pediatric Use (8.4)].The most common adverse reactions (≥ 20%) in order of decreasing frequency were fatigue, nausea, dizziness, vomiting, anemia, increased AST, cough, increased ALT, constipation, and diarrhea.The most common serious adverse reactions (≥ 2%) were pyrexia, diarrhea, sepsis, abdominal pain, dehydration, cellulitis, and vomiting. Grade 3 or 4 adverse reactions occurred in 51% of patients; adverse reactions leading to dose interruption or reduction occurred in 37% of patients and 13% permanently discontinued VITRAKVI for adverse reactions.The most common adverse reactions (1-2% each) that resulted in discontinuation of VITRAKVI were brain edema, intestinal perforation, pericardial effusion, pleural effusion, small intestinal obstruction, dehydration, fatigue, increased ALT, increased AST, enterocutaneous fistula, increased amylase, increased lipase, muscular weakness, abdominal pain, asthenia, decreased appetite, dyspnea, hyponatremia, jaundice, syncope, vomiting, acute myeloid leukemia, and nausea.The most common adverse reactions (≥ 3%) resulting in dose modification (interruption or reduction) were increased ALT (6%), increased AST (6%), and dizziness (3%). Most (82%) adverse reactions leading to dose modification occurred during the first three months of exposure.Adverse reactions of VITRAKVI occurring in ≥ 10% of patients and laboratory abnormalities worsening from baseline in ≥ 5% of patients are summarized in Table 2 and Table 3, respectively.Table 2 Adverse Reactions Occurring in ≥ 10% of Patients Treated with VITRAKVIAdverse ReactionVITRAKVIN = 176All GradesNational Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE) v 4.03.(%)Grade 3-4One Grade 4 adverse reaction of pyrexia.(%)General   Fatigue373   Pyrexia181   Edema peripheral150Gastrointestinal   Nausea291   Vomiting261   Constipation 231   Diarrhea222   Abdominal pain132Nervous System   Dizziness281   Headache140Respiratory, Thoracic and Mediastinal   Cough260   Dyspnea182   Nasal congestion100Investigations   Increased weight154Musculoskeletal and Connective Tissue   Arthralgia141   Myalgia141   Muscular weakness130   Back pain121   Pain in extremity121Metabolism and Nutrition   Decreased appetite132Vascular   Hypertension112Injury, Poisoning and Procedural Complications   Fall101Table 3 Laboratory Abnormalities Occurring in ≥ 5% Patients Treated with VITRAKVILaboratory AbnormalityVITRAKVIDenominator for each laboratory parameter is based on the number of patients with a baseline and post-treatment laboratory value available which ranged from 170 to 174 patients.All GradesNCI-CTCAE v 4.03.(%)Grade 3-4(%)Chemistry   Increased ALT453   Increased AST453   Hypoalbuminemia352   Increased alkaline phosphatase303Hematology   Anemia4210   Neutropenia237

7.1 Effects Of Other Drugs On Vitrakvi

Strong CYP3A4 InhibitorsCoadministration of VITRAKVI with a strong CYP3A4 inhibitor may increase larotrectinib plasma concentrations, which may result in a higher incidence of adverse reactions [see Clinical Pharmacology (12.3)]. Avoid coadministration of VITRAKVI with strong CYP3A4 inhibitors, including grapefruit or grapefruit juice. If coadministration of strong CYP3A4 inhibitors cannot be avoided, modify VITRAKVI dose as recommended [see Dosage and Administration (2.4)].Strong CYP3A4 InducersCoadministration of VITRAKVI with a strong CYP3A4 inducer may decrease larotrectinib plasma concentrations, which may decrease the efficacy of VITRAKVI [see Clinical Pharmacology (12.3)]. Avoid coadministration of VITRAKVI with strong CYP3A4 inducers, including St. John’s wort. If coadministration of strong CYP3A4 inducers cannot be avoided, modify VITRAKVI dose as recommended [see Dosage and Administration (2.5)].

7.2 Effects Of Vitrakvi On Other Drugs

Sensitive CYP3A4 SubstratesCoadministration of VITRAKVI with sensitive CYP3A4 substrates may increase their plasma concentrations, which may increase the incidence or severity of adverse reactions [see Clinical Pharmacology (12.3)]. Avoid coadministration of VITRAKVI with sensitive CYP3A4 substrates. If coadministration of these sensitive CYP3A4 substrates cannot be avoided, monitor patients for increased adverse reactions of these drugs.

8.1 Pregnancy

Risk SummaryBased on literature reports in human subjects with congenital mutations leading to changes in TRK signaling, findings from animal studies, and its mechanism of action [see Clinical Pharmacology (12.1)], VITRAKVI can cause embryo-fetal harm when administered to a pregnant woman. There are no available data on VITRAKVI use in pregnant women. Administration of larotrectinib to pregnant rats and rabbits during the period of organogenesis resulted in malformations at maternal exposures that were approximately 11- and 0.7-times, respectively, those observed at the clinical dose of 100 mg twice daily (see Data). Advise pregnant women of the potential risk to a fetus.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.DataHuman DataPublished reports of individuals with congenital mutations in TRK pathway proteins suggest that decreases in TRK-mediated signaling are correlated with obesity, developmental delays, cognitive impairment, insensitivity to pain, and anhidrosis.Animal DataLarotrectinib crosses the placenta in animals. Larotrectinib did not result in embryolethality at maternally toxic doses [up to 40 times the human exposure based on area under the curve (AUC) at the clinical dose of 100 mg twice daily] in embryo-fetal development studies in pregnant rats dosed during the period of organogenesis; however, larotrectinib was associated with fetal anasarca in rats from dams treated at twice-daily doses of 40 mg/kg [11 times the human exposure (AUC) at the clinical dose of 100 mg twice daily]. In pregnant rabbits, larotrectinib administration was associated with omphalocele at twice-daily doses of 15 mg/kg (0.7 times the human exposure at the clinical dose of 100 mg twice daily).

8.2 Lactation

Risk SummaryThere are no data on the presence of larotrectinib or its metabolites in human milk and no data on its effects on the breastfed child or on milk production. Because of the potential for serious adverse reactions in breastfed children, advise women not to breastfeed during treatment with larotrectinib and for 1 week after the final dose.

8.3 Females And Males Of Reproductive Potential

Pregnancy TestingVerify pregnancy status in females of reproductive potential prior to initiating VITRAKVI [see Use in Specific Populations (8.1)].ContraceptionVITRAKVI can cause embryo-fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)].FemalesAdvise female patients of reproductive potential to use effective contraception during treatment with VITRAKVI and for at least 1 week after the final dose.MalesAdvise males with female partners of reproductive potential to use effective contraception during treatment with VITRAKVI and for 1 week after the final dose.InfertilityFemalesBased on histopathological findings in the reproductive tracts of female rats in a 1-month repeated-dose study, VITRAKVI may reduce fertility [See Nonclinical Toxicology (13.1)].

8.4 Pediatric Use

The safety and effectiveness of VITRAKVI in pediatric patients was established based upon data from three multicenter, open-label, single-arm clinical trials in adult or pediatric patients 28 days and older [see Adverse Reactions (6.1), Clinical Studies (14)].The efficacy of VITRAKVI was evaluated in 12 pediatric patients and is described in the Clinical Studies section [see Clinical Studies (14)]. The safety of VITRAKVI was evaluated in 44 pediatric patients who received VITRAKVI. Of these 44 patients, 27% were 1 month to < 2 years (n = 12), 43% were 2 years to < 12 years (n = 19), and 30% were 12 years to < 18 years (n = 13); 43% had metastatic disease and 57% had locally advanced disease; and 91% had received prior treatment for their cancer, including surgery, radiotherapy, or systemic therapy. The most common cancers were infantile fibrosarcoma (32%), soft tissue sarcoma (25%), primary CNS tumors (20%), and thyroid cancer (9%). The median duration of exposure was 5.4 months (range: 9 days to 1.9 years).Due to the small number of pediatric and adult patients, the single arm design of clinical studies of VITRAKVI, and confounding factors such as differences in susceptibility to infections between pediatric and adult patients, it is not possible to determine whether differences in the incidence of adverse reactions to VITRAKVI are related to patient age or other factors. Adverse reactions and laboratory abnormalities of Grade 3 or 4 severity occurring more frequently (at least a 5% increase in per-patient incidence) in pediatric patients compared to adult patients were increased weight (11% vs. 2%) and neutropenia (20% vs. 2%). One of the 44 pediatric patients discontinued VITRAKVI due to an adverse reaction (Grade 3 increased ALT).The pharmacokinetics of VITRAKVI in the pediatric population were similar to those seen in adults [see Clinical Pharmacology (12.3)].Juvenile Animal Toxicity DataLarotrectinib was administered in a juvenile toxicity study in rats at twice daily doses of 0.2, 2 and 7.5 mg/kg from postnatal day (PND) 7 to 27 and at twice daily doses of 0.6, 6 and 22.5mg/kg between PND 28 and 70. The dosing period was equivalent to human pediatric populations from newborn to adulthood. The doses of 2/6 mg/kg twice daily [approximately 0.7 times the human exposure (AUC) at the clinical dose of 100 mg twice daily] and 7.5/22.5 mg/kg twice daily (approximately 4 times the human exposure at the clinical dose of 100 mg twice daily) resulted in mortality between PND 9 to 99; a definitive cause of death was not identified in the majority of cases.The main findings were transient central nervous system-related signs including head flick, tremor, and circling in both sexes. An increase in the number of errors in a maze swim test occurred in females at exposures of approximately 4 times the human exposure (AUC) at the clinical dose of 100 mg twice daily. Decreased growth and delays in sexual development occurred in the mid- and high-dose groups. Mating was normal in treated animals, but a reduction in pregnancy rate occurred at the high-dose of 7.5/22.5 mg/kg twice daily (approximately 4 times the human exposure at the clinical dose of 100 mg twice daily).

8.5 Geriatric Use

Of 176 patients in the overall safety population who received VITRAKVI, 22% of patients were ≥ 65 years of age and 5% of patients were ≥ 75 years of age. Clinical studies of VITRAKVI did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.

8.6 Hepatic Impairment

No dose adjustment is recommended for patients with mild hepatic impairment (Child-Pugh A). Larotrectinib clearance was reduced in subjects with moderate (Child-Pugh B) to severe (Child-Pugh C) hepatic impairment [see Clinical Pharmacology (12.3)]. Reduce VITRAKVI dose as recommended [see Dosage and Administration (2.6)].

8.7 Renal Impairment

No dose adjustment is recommended for patients with renal impairment of any severity [see Clinical Pharmacology (12.3)].

11 Description

Larotrectinib is a kinase inhibitor. VITRAKVI (larotrectinib) capsules and oral solution are formulated using larotrectinib sulfate. The molecular formula for larotrectinib sulfate is C21H24F2N6O6S and the molecular weight is 526.51 g/mol for the sulfate salt and 428.44 g/mol for the free base. The chemical name is (3S)-N-{5-[(2R)-2-(2,5-difluorophenyl)-1-pyrrolidinyl]pyrazolo[1,5-a]pyrimidin-3-yl}-3-hydroxy-1-pyrrolidinecarboxamide sulfate. Larotrectinib sulfate has the following chemical structure:Larotrectinib sulfate is an off-white to pinkish yellow solid that is not hygroscopic. The aqueous solubility of larotrectinib at 37°C is pH dependent (very soluble at pH 1.0 and freely soluble at pH 6.8, according to USP descriptive terms of solubility).VITRAKVI (larotrectinib) capsules and oral solution are for oral use. Each capsule contains 25 mg or 100 mg larotrectinib (30.7 mg and 123 mg larotrectinib sulfate, respectively) in a hard gelatin capsule. The capsule is composed of gelatin, titanium dioxide, and edible ink.The oral solution contains 20 mg/mL larotrectinib (24.6 mg/mL larotrectinib sulfate) and the following inactive ingredients: purified water, hydroxypropyl betadex, sucrose, glycerin, sorbitol, citric acid, sodium phosphate, sodium citrate dihydrate, propylene glycol and flavoring. Preserved with methylparaben and potassium sorbate.

12.1 Mechanism Of Action

Larotrectinib is an inhibitor of the tropomyosin receptor kinases (TRK), TRKA, TRKB, and TRKC. In a broad panel of purified enzyme assays, larotrectinib inhibited TRKA, TRKB, and TRKC with IC50 values between 5-11 nM. One other kinase TNK2 was inhibited at approximately 100-fold higher concentration. TRKA, B, and C are encoded by the genes NTRK1, NTRK2, and NTRK3. Chromosomal rearrangements involving in-frame fusions of these genes with various partners can result in constitutively-activated chimeric TRK fusion proteins that can act as an oncogenic driver, promoting cell proliferation and survival in tumor cell lines.In in vitro and in vivo tumor models, larotrectinib demonstrated anti-tumor activity in cells with constitutive activation of TRK proteins resulting from gene fusions, deletion of a protein regulatory domain, or in cells with TRK protein overexpression. Larotrectinib had minimal activity in cell lines with point mutations in the TRKA kinase domain, including the clinically identified acquired resistance mutation, G595R. Point mutations in the TRKC kinase domain with clinically identified acquired resistance to larotrectinib include G623R, G696A, and F617L.

12.2 Pharmacodynamics

Cardiac ElectrophysiologyAt a dose 9-fold higher than the recommended adult dose, VITRAKVI does not prolong QTc intervals to any clinically relevant extent.

12.3 Pharmacokinetics

The pharmacokinetics of larotrectinib were studied in healthy subjects and adult and pediatric patients with locally advanced or metastatic solid tumors. In healthy subjects who received a single dose of VITRAKVI capsules, systemic exposure (Cmax and AUC) of larotrectinib was dose proportional over the dose range of 100 mg to 400 mg (1 to 4 times the recommended adult dose) and slightly greater than proportional at doses of 600 mg to 900 mg (6 to 9 times the recommended adult dose). In adult patients who received VITRAKVI capsules 100 mg twice daily in Study LOXO-TRK-14001, peak plasma levels (Cmax) of larotrectinib were achieved at approximately 1 hour after dosing and steady-state was reached within 3 days. Mean steady-state larotrectinib [coefficient of variation (CV%)] for Cmax was 788 (81%) ng/mL and AUC0-24hr was 4351 (97%) ng*h/mL.AbsorptionThe mean absolute bioavailability of VITRAKVI capsules was 34% (range: 32% to 37%). In healthy subjects, the AUC of VITRAKVI oral solution was similar to that of the capsules and the Cmax was 36% higher with the oral solution.Effect of FoodThe AUC of larotrectinib was similar and the Cmax was reduced by 35% after oral administration of a single 100 mg capsule of VITRAKVI to healthy subjects taken with a high-fat meal (approximately 900 calories, 58 grams carbohydrate, 56 grams fat and 43 grams protein) compared to the Cmax and AUC in the fasted state.DistributionThe mean (CV%) volume of distribution (Vss) of larotrectinib is 48 (38%) L following intravenous administration of larotrectinib in healthy subjects.Larotrectinib is 70% bound to human plasma proteins in vitro and binding is independent of drug concentrations. The blood-to-plasma concentration ratio is 0.9.EliminationThe mean (CV%) clearance (CL/F) of larotrectinib is 98 (44%) L/h and the half-life is 2.9 hours following oral administration of VITRAKVI in healthy subjects.MetabolismLarotrectinib is metabolized predominantly by CYP3A4. Following oral administration of a single [14C] radiolabeled 100 mg dose of larotrectinib to healthy subjects, unchanged larotrectinib constituted 19% and an O-linked glucuronide constituted 26% of the major circulating radioactive drug components in plasma.ExcretionFollowing oral administration of a single [14C] radiolabeled 100 mg dose of larotrectinib to healthy subjects, 58% (5% unchanged) of the administered radioactivity was recovered in feces and 39% (20% unchanged) was recovered in urine.Specific PopulationsAge (range: 28 days to 82 years), sex, and body weight (range: 3.8 kg to 179 kg) had no clinically meaningful effect on the pharmacokinetics of larotrectinib.Pediatric PatientsIn pediatric patients, the larotrectinib geometric mean (%CV) AUC0-24hr by age subgroup was: 3348 (66%) ng*h/mL in patients 1 month to < 2 years (n = 9), 4135 (36%) ng*h/mL in patients 2 to < 12 years (n = 15), and 3108 (69%) ng*h/mL and in patients 12 to < 18 years (n = 9).Patients with Renal ImpairmentFollowing oral administration of a single 100 mg dose of VITRAKVI capsules in subjects with end-stage renal disease (e.g., subjects who required dialysis), the AUC0-INF of larotrectinib increased 1.5-fold and Cmax increased 1.3-fold as compared to that in subjects with normal renal function (creatinine clearance ≥ 90 mL/min as estimated by Cockcroft-Gault). The pharmacokinetics of VITRAKVI in patients with moderate to severe renal impairment (creatinine clearance ≤ 60 mL/min) have not been studied.Patients with Hepatic ImpairmentFollowing oral administration of a single 100 mg dose of VITRAKVI capsules, the AUC0-INF of larotrectinib increased 1.3-fold in subjects with mild hepatic impairment (Child-Pugh A), 2-fold in subjects with moderate hepatic impairment (Child-Pugh B) and 3.2-fold in subjects with severe hepatic impairment (Child-Pugh C) as compared to that in subjects with normal hepatic function. The Cmax was similar in subjects with mild and moderate hepatic impairment and the Cmax of larotrectinib increased 1.5-fold in subjects with severe hepatic impairment as compared to that in subjects with normal hepatic function [see Dosage and Administration (2.6), Use in Specific Populations (8.6)].Drug Interaction StudiesClinical StudiesEffect of Strong CYP3A Inhibitors: Coadministration of a single 100 mg dose of VITRAKVI capsules with a strong CYP3A inhibitor (itraconazole) increased the AUC0-INF of larotrectinib by 4.3-fold and the Cmax by 2.8-fold as compared to VITRAKVI administered alone [see Dosage and Administration (2.4), Drug Interactions (7.1)]. The effects of CYP3A moderate and weak inhibitors on the pharmacokinetics of larotrectinib have not been studied.Effect of Strong CYP3A Inducers: Coadministration of a single 100 mg dose of VITRAKVI capsules with a strong CYP3A inducer (rifampin) decreased the AUC0-INF of larotrectinib by 81% and of Cmax by 71% as compared to VITRAKVI administered alone [see Dosage and Administration (2.5), Drug Interactions (7.1)]. The effects of CYP3A weak and moderate inducers on the pharmacokinetics of larotrectinib have not been studied.Effect of Strong P-glycoprotein (P-gp) Inhibitors: Coadministration of a single 100 mg dose of VITRAKVI capsules with a P-gp inhibitor (rifampin) increased the AUC0-INF of larotrectinib by 1.7-fold and the Cmax by 1.8-fold as compared to VITRAKVI administered alone.Effect of Larotrectinib on CYP3A4 Substrates: Coadministration of VITRAKVI capsules 100 mg twice daily with a sensitive CYP3A4 substrate (midazolam) increased both the AUC0-INF and Cmax of midazolam by 1.7-fold as compared to midazolam administered alone. The AUC0-INF and Cmax of 1-hydroxymidazolam, the main metabolite of midazolam, were both increased 1.4-fold as compared to when midazolam was administered alone [see Drug Interactions (7.2)].In Vitro StudiesEffect of Transporter on Larotrectinib: Larotrectinib is a substrate for P-gp and BCRP. Larotrectinib is not a substrate of OAT1, OAT3, OCT1, OCT2, OATP1B1, or OATP1B3.Effect of Larotrectinib on Transporters: Larotrectinib is not an inhibitor of BCRP, P-gp, OAT1, OAT3, OCT1, OCT2, OATP1B1, OATP1B3, BSEP, MATE1 and MATE2-K at clinically relevant concentrations.Effect of Larotrectinib on CYP Substrates: Larotrectinib is not an inhibitor or inducer of CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, or CYP2D6 at clinically relevant concentrations.

13.1 Carcinogenesis, Mutagenesis, Impairment Of Fertility

Carcinogenicity studies have not been conducted with larotrectinib. Larotrectinib was not mutagenic in the in vitro bacterial reverse mutation (Ames) assays, with or without metabolic activation, or in the in vitro mammalian mutagenesis assays, with or without metabolic activation. In vivo, larotrectinib was negative in the mouse micronucleus test.Fertility studies with larotrectinib have not been conducted. In a 3-month repeat-dose toxicity study in the rat, larotrectinib had no effects on spermatogenesis at 75 mg/kg/day (approximately 7 times the human exposure at the 100 mg twice daily dose). Additionally, larotrectinib had no histological effects on the male reproductive tract in rats or monkeys at doses resulting in exposures up to 10 times the human exposure (AUC0-24hr) at the 100 mg twice daily clinical dose.In a 1-month repeat-dose study in the rat, decreased uterine weight and uterine atrophy were seen at 200 mg/kg/day [approximately 45 times the human exposure (AUC) at the 100 mg twice daily dose]. Fewer corpora lutea and increased incidence of anestrus were also noted at doses ≥ 60 mg/kg/day (approximately 10 times the human exposure at the 100 mg twice daily dose). Decreased fertility occurred in a juvenile animal study [see Use in Specific Populations (8.4)]. There were no findings in female reproductive organs in repeat-dose studies in monkeys at exposures up to 22 times the human exposure at the 100 mg twice daily dose.

13.2 Animal Toxicology And/Or Pharmacology

In general toxicology studies conducted in rats and monkeys and in reproductive toxicology studies conducted in rats and rabbits, administration of larotrectinib led to increased food consumption and increased body weight at doses resulting in exposures 0.6 times the human exposure at the 100 mg twice daily clinical dose. Obesity has also been one phenotypic outcome of some human syndromes resulting from congenital mutations in NTRK2 resulting in altered TRK signaling.

14 Clinical Studies

  • The efficacy of VITRAKVI was evaluated in pediatric and adult patients with unresectable or metastatic solid tumors with a NTRK gene fusion enrolled in one of three multicenter, open-label, single-arm clinical trials: Study LOXO-TRK-14001 (NCT02122913), SCOUT (NCT02637687), and NAVIGATE (NCT02576431). All patients were required to have progressed following systemic therapy for their disease, if available, or would have required surgery with significant morbidity for locally advanced disease.Adult patients received VITRAKVI 100 mg orally twice daily and pediatric patients (18 years or younger) received VITRAKVI 100 mg/m2 up to a maximum dose of 100 mg orally twice daily until unacceptable toxicity or disease progression. Identification of positive NTRK gene fusion status was prospectively determined in local laboratories using next generation sequencing (NGS) or fluorescence in situ hybridization (FISH). NTRK gene fusions were inferred in three patients with infantile fibrosarcoma who had a documented ETV6 translocation identified by FISH. The major efficacy outcome measures were overall response rate (ORR) and duration of response (DOR), as determined by a blinded independent review committee (BIRC) according to RECIST v1.1.The assessment of efficacy was based on the first 55 patients with solid tumors with an NTRK gene fusion enrolled across the three clinical trials. Baseline characteristics were: median age 45 years (range 4 months to 76 years); 22% <18 years of age, and 78% ≥18 years of age; 53% male; 67% White; 7% Hispanic/Latino, 4% Asian, 4% Black; and ECOG performance status 0-1 (93%) or 2 (7%). Eighty-two percent of patients had metastatic disease and 18% had locally advanced, unresectable disease. Ninety-eight percent of patients had received prior treatment for their cancer, including surgery, radiotherapy, or systemic therapy. Of these, 82% (n = 45) received prior systemic therapy with a median of two prior systemic regimens and 35% (n = 19) received three or more prior systemic regimens. The most common cancers were salivary gland tumors (22%), soft tissue sarcoma (20%), infantile fibrosarcoma (13%), and thyroid cancer (9%). A total of 50 patients had NTRK gene fusions detected by NGS and 5 patients had NTRK gene fusions detected by FISH.Efficacy results are summarized in Tables 4, 5, and 6. Table 4Efficacy Results for Patients with Solid Tumors Harboring NTRK Gene FusionsEfficacy ParameterVITRAKVIN = 55Overall response rate (95% CI)75% (61%, 85%)   Complete response rate22%   Partial response rateIncludes one pediatric patient with unresectable infantile fibrosarcoma who underwent resection following partial response and who remained disease-free at data cutoff.53%Duration of responseMedian duration of response not reached at time of data cutoff.N = 41   Range (months)1.6+, 33.2+   % with duration ≥ 6 months73%   % with duration ≥ 9 months3 patients with an ongoing response were followed < 9 months from onset of response.63%   % with duration ≥ 12 months10 patients with an ongoing response were followed < 12 months from onset of response.39%+ Denotes ongoing response.Table 5 Efficacy Results by Tumor TypeTumor TypePatients(N=55)ORRDOR%95% CIRange(months)Soft tissue sarcoma1191%(59%, 100%)3.6, 33.2+Salivary gland1283%(52%, 98%)7.7, 27.9+Infantile fibrosarcoma7100%(59%, 100%)1.4+, 10.2+Thyroid5100%(48%, 100%)3.7, 27.0+Lung475%(19%, 99%)8.2, 20.3+Melanoma450%NA1.9, 17.5+Observed values at data cutoff, not a range.Colon425%NA5.6Gastrointestinal stromal tumor3100%(29%, 100%)9.5, 17.3Cholangiocarcinoma2SD, NENANAAppendix1SDNANABreast1PDNANAPancreas1SDNANANA = not applicable due to small numbers or lack of response; CR = complete response; PR = partial response; NE = not evaluable; SD = stable disease; PD = progressive disease.+ Denotes ongoing response.Table 6 Efficacy Results by NTRK Fusion PartnerNTRK PartnerFusion partners identified in the primary analysis set (N=55) may not represent all potential fusion partners.Patients(N=55)ORRDOR%95% CIRange(months)ETV6-NTRK32584%(64%, 96%)3.7, 27.9+TPM3-NTRK1956%(21%, 86%)3.7, 10.3+LMNA-NTRK1540%NA5.6, 33.2+Inferred ETV6-NTRK33100%(29%, 100%)1.4+, 2.7Duration of response censored at the time of surgery for one pediatric patient with unresectable infantile fibrosarcoma who underwent resection following partial response and who remained disease-free at data cutoff.IRF2BP2-NTRK12CR, PRNA3.7, 20.3+SQSTM1-NTRK12PR, PRNA9.9, 12.9+PDE4DIP-NTRK11PRNA3.6+ Observed values at data cutoff, not a range.PPL-NTRK11CRNA12.0+ STRN-NTRK21PRNA5.6TPM4-NTRK31CRNA23.6TPR-NTRK11PRNA8.2TRIM63-NTRK11PRNA1.9+ CTRC-NTRK11SDNANAGON4L-NTRK11NENANAPLEKHA6-NTRK11SDNANACR = complete response; PR = partial response; NE = not evaluable; SD = stable disease; NA = not applicable.+ Denotes ongoing response.

Instructions For Use

  • INSTRUCTIONS FOR USEVITRAKVI (vi trak vee)(larotrectinib)oral solutionRead this Instructions for Use before you take or give a dose of VITRAKVI oral solution for the first time and each time you get a refill. There may be new information. This information does not take the place of talking with your healthcare provider about your medical condition or your treatment.Your healthcare provider should show you how to correctly measure the prescribed dose of VITRAKVI oral solution before you take or give a dose for the first time.Important information about measuring VITRAKVI oral solution: •Always use the oral syringes provided with VITRAKVI to make sure that you correctly measure the prescribed dose. •When you receive VITRAKVI oral solution from your healthcare provider or pharmacist, you will get a box that contains 1 glass bottle of VITRAKVI oral solution and a bottle adaptor. You may receive more than 1 box of VITRAKVI oral solution. •You will receive five 1 mL or 5 mL oral syringes that are marked to help you correctly measure the prescribed dose of VITRAKVI oral solution. Each oral syringe may be used over a 7-day period. Do not use a household teaspoon to measure the dose.Supplies needed to take or give a dose of VITRAKVI oral solutionHow to prepare a dose of VITRAKVI oral solution:Step 1: Remove the VITRAKVI oral solution bottle from the box. Place the bottle on a flat work surface. Open the bottle by pushing down firmly on the child-resistant cap and turning it in the direction of the arrow (counter-clockwise) See Figure B. Do not throw away the child-resistant cap.Step 2: Insert the bottle adaptor by pressing it into the bottle neck and make sure it is secure. See Figure C. Do not remove the bottle adaptor. If the bottle adaptor is missing, talk to your healthcare provider.Step 3: Remove the oral syringe from the wrapper. Throw the wrapper away in your household trash. The barrel of the oral syringe has markings in milliliters (mL). Look at the markings on the barrel of the oral syringe and find the mL marking that matches the VITRAKVI oral solution dose in mL prescribed by your healthcare provider. See Figure D.Step 4: With the bottle on your flat work surface, use 1 hand to hold the bottle upright. Using your other hand, push the air out of the oral syringe by pushing the plunger down. Then, insert the tip of the oral syringe into the bottle adaptor at the top of the bottle. See Figure E. The tip of the oral syringe should fit snugly into the hole of the bottle adaptor.Step 5: Use 1 hand to hold the oral syringe in place. With the other hand, turn the bottle upside down. Pull back on the plunger until the top of the plunger lines up with the marking on the barrel of the oral syringe that matches the dose of VITRAKVI oral solution prescribed by your healthcare provider. See Figure "F". Your dose may be different than the dose shown in Figure F.Step 6: Check for air bubbles in the oral syringe. If you see air bubbles, push up gently on the plunger to push any large air bubbles back into the bottle. Then, pull back on the plunger to the prescribed dose. See Figure G.Step 7: Turn the bottle upright again and place it on your work surface. Remove the oral syringe from the bottle adaptor by gently pulling up on the syringe barrel. See Figure H. Do not push on the plunger during this step. The bottle adaptor should stay attached to the bottle.Giving a dose of VITRAKVI oral solution by mouth:Step 8: Place the tip of the oral syringe into the child’s mouth against the inside of the cheek. Slowly squirt VITRAKVI oral solution into the mouth by pressing down on the plunger and allow the child to swallow. See Figure I. •The child should be kept in an upright position for a few minutes right after giving a dose of VITRAKVI. •If the child spits up a dose or you are not sure the entire dose was given, do not give another dose. Wait until the next scheduled dose.Step 9: Replace the child-resistant cap on the bottle of VITRAKVI oral solution. Do not remove the bottle adaptor. Close the bottle by turning the bottle cap in the direction of the arrow (clockwise). See Figure J.Cleaning instructions for oral syringesFollow the instructions below for cleaning the oral syringe (Step 10 through Step 16). After 7 days of use, throw away the oral syringe in your household trash. Use a new one for the next 7 days.Step 10: Remove plunger from the barrel of the oral syringe. See Figure K.Step 11: Rinse the barrel and plunger in warm running water to help ensure that all of the medicine has been removed from the oral syringe. See Figure L.Do not boil the oral syringe.Step 12: Re-insert the plunger into the barrel of the oral syringe. See Figure M.Step 13: Draw warm water several times into the oral syringe and squirt out again until all of the medicine has been removed from the oral syringe. See Figure N.Step 14: Disassemble the oral syringe, and rinse the barrel and plunger again with warm water. See Figure O.Step 15: Shake off excess water or wipe off the outside, and then place the barrel and plunger on a clean, dry paper towel to dry. See Figure P.Step 16: Assemble the oral syringe and store in a clean place until the next use.Replace the oral syringe after 7 days of use, or if: •there is any damage to the barrel, plunger, or tip •the dosage marking is no longer clearly recognizable or •it becomes difficult to move the plungerHow should I store VITRAKVI oral solution? •Store VITRAKI oral solution in a refrigerator between 36° F to 46° F (2° C to 8° C).
