  • 5 WARNINGS AND PRECAUTIONS

    5.1 Cardiomyopathy

    Cardiomyopathy, defined as a decrease in left ventricular ejection fraction (LVEF) ≥ 10% below baseline, occurred in 23% of 74 pediatric patients who received KOSELUGO in SPRINT [see Adverse Reactions (6.1)]. Four percent of patients experienced decreased LVEF below the institutional lower limit of normal (LLN). Grade 3 decreased LVEF occurred in one patient and resulted in dose reduction. All patients with decreased LVEF were asymptomatic and identified during routine echocardiography. Decreased LVEF resolved in 71% of these patients.

    Left ventricular dysfunction or decreased LVEF resulting in permanent discontinuation of KOSELUGO occurred in an unapproved population of adult patients with multiple tumor types who received KOSELUGO. Decreased LVEF resulting in permanent discontinuation of KOSELUGO occurred in a pediatric population with NF1 in an expanded access program.

    The safety of KOSELUGO has not been established in patients with a history of impaired LVEF or a baseline ejection fraction that is below the institutional LLN

    Assess ejection fraction by echocardiogram prior to initiating treatment, every 3 months during the first year of treatment, every 6 months thereafter, and as clinically indicated. Withhold, reduce dose, or permanently discontinue KOSELUGO based on severity of adverse reaction [see Dosage and Administration (2.2)]. In patients who interrupt KOSELUGO for decreased LVEF, obtain an echocardiogram or a cardiac MRI every 3 to 6 weeks. Upon resolution of decreased LVEF to greater than or equal to the institutional LLN, obtain an echocardiogram or a cardiac MRI every 2 to 3 months or as directed by the cardiologist.

    5.2 Ocular Toxicity

    Blurred vision, photophobia, cataracts, and ocular hypertension occurred in 15% of 74 pediatric patients receiving KOSELUGO in SPRINT. Blurred vision resulted in dose interruption in 2.7% of patients. Ocular toxicity resolved in 82% of 11 patients.

    Serious ocular toxicities including retinal vein occlusion (RVO) and retinal pigment epithelial detachment (RPED), occurred in an unapproved population of adult patients with multiple tumor types who received KOSELUGO as a single agent or in combination with other anti-cancer agents. RPED occurred in the pediatric population during treatment with single agent KOSELUGO and resulted in permanent discontinuation.

    Conduct comprehensive ophthalmic assessments prior to initiating KOSELUGO, at regular intervals during treatment, and for new or worsening visual changes. Permanently discontinue KOSELUGO in patients with RVO. Withhold KOSELUGO in patients with RPED, follow up with optical coherence tomography assessments every 3 weeks until resolution, and resume KOSELUGO at a reduced dose. For other ocular toxicities, withhold, reduce dose, or permanently discontinue KOSELUGO based on severity of the adverse reaction [see Dosage and Administration (2.2)].

    5.3 Gastrointestinal Toxicity

    Diarrhea occurred in 77% of 74 pediatric patients who received KOSELUGO in SPRINT, including Grade 3 in 15% of patients. Diarrhea resulting in permanent discontinuation occurred in 1.4% of patients. Diarrhea resulting in dose interruption or dose reduction occurred in 15% and 1.4% of patients, respectively. The median time to first onset of diarrhea was 17 days and the median duration was 2 days.

    Serious gastrointestinal toxicities, including perforation, colitis, ileus, and intestinal obstruction, occurred in an unapproved population of adult patients with multiple tumor types who received KOSELUGO as a single agent or in combination with other anti-cancer agents. Colitis occurred in an unapproved population of pediatric patients with multiple tumor types who received KOSELUGO as a single agent.

    Advise patients to start an anti-diarrheal agent (e.g., loperamide) immediately after the first episode of unformed, loose stool and to increase fluid intake during diarrhea episodes. Withhold, reduce dose, or permanently discontinue KOSELUGO based on severity of adverse reaction [see Dosage and Administration (2.2)].

    5.4 Skin Toxicity

    Rash occurred in 91% of 74 pediatric patients who received KOSELUGO in SPRINT. The most frequent rashes included dermatitis acneiform (54%), maculopapular rash (39%), and eczema (28%). Grade 3 rash occurred in 8% of patients. Rash resulted in dose interruption in 11% of patients and dose reduction in 4% of patients.

    Other skin toxicities, including severe palmar-plantar erythrodysesthesia syndrome (PPES), occurred in an unapproved population of adult patients with multiple tumor types who received KOSELUGO as a single agent or in combination with other anti-cancer agents.

    Monitor for severe skin rashes. Withhold, reduce dose, or permanently discontinue KOSELUGO based on severity of adverse reaction [see Dosage and Administration (2.3)].

    5.5 Increased Creatinine Phosphokinase

    Increased creatinine phosphokinase (CPK) occurred in 76% of 74 pediatric patients who received KOSELUGO in SPRINT, including Grade 3 or 4 in 9% of patients. Increased CPK resulted in dose reduction in 7% of patients. Increased CPK concurrent with myalgia occurred in 8% of patients, including one patient who permanently discontinued KOSELUGO for myalgia.

    Rhabdomyolysis occurred in an unapproved adult population who received KOSELUGO as a single agent.

    Obtain serum CPK prior to initiating KOSELUGO, periodically during treatment, and as clinically indicated. If increased CPK occurs, evaluate patients for rhabdomyolysis or other causes. Withhold, reduce dose, or permanently discontinue KOSELUGO based on severity of adverse reaction [see Dosage and Administration (2.3)].

    5.6 Increased Levels of Vitamin E and Risk of Bleeding

    KOSELUGO capsules contain vitamin E (10 mg capsules contain 32 mg vitamin E as the excipient, D-alpha-tocopheryl polyethylene glycol 1000 succinate (TPGS); while KOSELUGO 25 mg capsules contain 36 mg vitamin E as TPGS). Vitamin E can inhibit platelet aggregation and antagonize vitamin K-dependent clotting factors. Daily vitamin E intake that exceeds the recommended or safe limits may increase the risk of bleeding. Supplemental vitamin E is not recommended if daily vitamin E intake (including the amount of vitamin E in KOSELUGO and supplement) will exceed the recommended or safe limits.

    An increased risk of bleeding in patients may occur in patients who are coadministered vitamin-K antagonists or anti-platelet antagonists with KOSELUGO. Monitor for bleeding in these patients. Increase international normalized ratio (INR) monitoring, as appropriate, in patients taking a vitamin-K antagonist. Perform anticoagulant assessments, including INR or prothrombin time, more frequently and adjust the dose of vitamin K antagonists or anti-platelet agents as appropriate [see Drug Interactions (7.1)].

    5.7 Embryo-Fetal Toxicity

    Based on findings from animal studies and its mechanism of action, KOSELUGO can cause fetal harm when administered to a pregnant woman. In animal reproduction studies, administration of selumetinib to mice during organogenesis caused reduced fetal weight, adverse structural defects, and effects on embryo-fetal survival at approximate exposures > 5 times the human exposure at the clinical dose of 25 mg/m2 twice daily. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with KOSELUGO and for 1 week after the last dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with KOSELUGO and for 1 week after the last dose [see Use in Specific Populations (8.1, 8.3)].

  • 6 ADVERSE REACTIONS

    The following clinically significant adverse reactions are described elsewhere in the labeling:

    6.1 Clinical Trials 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.

    The data in the WARNINGS AND PRECAUTIONS reflects exposure to KOSELUGO in 74 pediatric patients who received a dosage ranging from 20 mg/m2 to 30 mg/m2 orally twice daily in SPRINT. Among these patients, the duration of KOSELUGO exposure, including dose interruptions, was 12 months or longer (91%), more than 2 years (74%), or more than 4 years (23%). The WARNINGS AND PRECAUTIONS also includes additional data from adult and pediatric patients who received KOSELUGO administered at various doses across a range of tumors in other clinical trials.

    Neurofibromatosis Type 1 (NF1) with Inoperable Plexiform Neurofibromas (PN)

    The safety of KOSELUGO was evaluated in SPRINT Phase II Stratum 1 [see Clinical Studies (14)]. Eligible patients were 2-18 years of age with NF1 who had inoperable PN that was causing significant morbidity. Patients were excluded for abnormal LVEF, uncontrolled hypertension (blood pressure > the 95th percentile for age, height, and sex), any current or past history of RVO or RPED, intraocular pressure > 21 mmHg (or upper limit of normal adjusted by age), uncontrolled glaucoma, and inability to swallow whole capsules. Patients received KOSELUGO 25 mg/m2 orally twice daily (n=50). Among these patients, 88% were exposed for 12 months or longer and 66% were exposed for greater than 2 years.

    Serious adverse reactions occurred in 24% of patients who received KOSELUGO. Serious adverse reactions that occurred in 2 or more patients were anemia, hypoxia and diarrhea.

    Permanent discontinuation due to an adverse reaction occurred in 12% of patients who received KOSELUGO. Adverse reactions resulting in permanent discontinuation of KOSELUGO included increased creatinine, increased weight, diarrhea, paronychia, malignant peripheral nerve sheath tumor, acute kidney injury, and skin ulcer.

    Dosage interruptions and dose reductions due to adverse reactions occurred in 80% and 24% of patients who received KOSELUGO, respectively. Adverse reactions requiring a dosage interruption or reduction in ≥ 5% of patients were vomiting, paronychia, diarrhea, nausea, abdominal pain, rash, skin infection, influenza-like illness, pyrexia and weight gain.

    The most common adverse reactions (≥ 40%) were vomiting, rash (all), abdominal pain, diarrhea, nausea, dry skin, fatigue, musculoskeletal pain, pyrexia, acneiform rash, stomatitis, headache, paronychia, and pruritis.

    7.1 Effect of Other Drugs on KOSELUGO

    Strong or Moderate CYP3A4 Inhibitors or Fluconazole

    Clinical Impact

    • Concomitant use of KOSELUGO with a strong or moderate CYP3A4 inhibitor or fluconazole increased selumetinib plasma concentrations [see Clinical Pharmacology (12.3)], which may increase the risk of adverse reactions.

    Management

    • Avoid coadministration of strong or moderate CYP3A4 inhibitors or fluconazole with KOSELUGO. If coadministration with strong or moderate CYP3A4 inhibitors or fluconazole cannot be avoided, reduce KOSEULGO dosage [see Dosage and Administration (2.4)].

    Strong or Moderate CYP3A4 Inducers

    Clinical Impact

    • Concomitant use of KOSELUGO with a strong or moderate CYP3A4 inducer decreased selumetinib plasma concentrations [see Clinical Pharmacology (12.3)], which may reduce KOSELUGO efficacy.

    Management

    • Avoid concomitant use of strong or moderate CYP3A4 inducers with KOSELUGO.

    Vitamin E

    Clinical Impact

    • KOSELUGO contains vitamin E and daily vitamin E intake that exceeds the recommended or safe limits may increase the risk of bleeding. An increased risk of bleeding may occur in patients taking a vitamin-K antagonist or an anti-platelet agent with KOSELUGO.

    Management

    • Supplemental vitamin E is not recommended if daily vitamin E intake (including the amount of vitamin E in KOSELUGO and supplement) will exceed the recommended or safe limits.
    • Monitor for bleeding in patients coadministered a vitamin-K antagonist or an antiplatelet agent with KOSELUGO. Increase INR monitoring, as appropriate, in patients taking a vitamin-K antagonist [see Warnings and Precautions (5.3)].
  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary

    Based on findings from animal studies and its mechanism of action [see Clinical Pharmacology (12.1)], KOSELUGO can cause fetal harm when administered to a pregnant woman. There are no available data on the use of KOSELUGO in pregnant women to evaluate drug-associated risk. In animal reproduction studies, administration of selumetinib to mice during organogenesis caused reduced fetal weight, adverse structural defects, and effects on embryofetal survival at exposures approximately > 5 times the human exposure at the clinical dose of 25 mg/m2 twice daily (see Data). Advise pregnant women of the potential risk to the 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.

    Data

    Animal Data

    In embryo-fetal development studies in mice at doses > 2.5 mg/kg twice daily (~5 times the human exposure based on area under the curve [AUC] at the clinical dose of 25 mg/m2 twice daily), selumetinib caused increases in post-implantation loss, a reduction in mean fetal and litter weights, and an increased occurrence of open eye and cleft palate, but did not induce significant maternal toxicity.

    Administration of selumetinib to pregnant mice from gestation Day 6 through lactation Day 20 resulted in reduced pup body weights and fewer pups met the pupil constriction criterion on day 21 post-partum. The incidence of malformations (e.g. prematurely open eye(s) and cleft palate) was increased even at the lowest dose of 0.5 mg/kg twice daily (maternal maximal concentration [Cmax] of ~0.6 times the human Cmax at the clinical dose of 25 mg/m2 twice daily).

    8.2 Lactation

    Risk Summary

    There are no data on the presence of selumetinib or its active metabolite in human milk or their effects on the breastfed child or milk production. Selumetinib and its active metabolite were present in the milk of lactating mice (see Data). Due to the potential for adverse reactions in a breastfed child, advise women not to breastfeed during treatment with KOSELUGO and for 1 week after the last dose.

    Data

    Animal Data

    Selumetinib and its active metabolite were present in milk from mice dosed with selumetinib throughout gestation and lactation, with a mean plasma/milk ratio of 1.5 in lactating dams dosed at 5 mg/kg twice daily. Administration of selumetinib to dams during gestation and early lactation was associated with adverse events in pups, including reduced growth rates and incidence of malformations [see Use in Specific Populations (8.1)].

    8.3 Females and Males of Reproductive Potential

    KOSELUGO can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)].

    Pregnancy Testing

    Verify the pregnancy status of females of reproductive potential prior to initiating KOSELUGO [see Use in Specific Populations (8.1)].

    Contraception

    Females

    Advise females of reproductive potential to use effective contraception during treatment and for 1 week after the last dose.

    Males

    Advise male patients with female partners of reproductive potential to use effective contraception during treatment with KOSELUGO and for 1 week after the last dose.

    8.4 Pediatric Use

    The safety and effectiveness have been established in pediatric patients 2 years of age and older with NF1 who have inoperable PN and the information on this use is discussed throughout the labeling. The safety and effectiveness of KOSELUGO have not been established in pediatric patients younger than 2 years of age.

    Animal Toxicity Data

    In 3-month general toxicology studies, male rats receiving selumetinib at doses ≥ 10 mg/kg daily (~60 times the human exposure based on AUC at the clinical dose of 25 mg/m2 twice daily) showed growth plate dysplasia.

    8.5 Geriatric Use

    Clinical studies did not include patients 65 years of age and older.

    8.6 Renal Impairment

    No dose adjustment is recommended in patients with renal impairment or those with End Stage Renal Disease [see Clinical Pharmacology (12.3)].

    8.7 Hepatic Impairment

    Selumetinib exposures increased in patients with moderate or severe hepatic impairment [see Clinical Pharmacology (12.3)]. Reduce the dose of KOSELUGO for patients with moderate hepatic impairment (Child-Pugh B). A recommended dosage of KOSELUGO for use in patients with severe hepatic impairment (Child-Pugh C) has not been established [see Dosage and Administration (2.3)].

  • 10 OVERDOSAGE

    Dialysis is not helpful as KOSELUGO is highly protein bound and is extensively metabolized.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Selumetinib is an inhibitor of mitogen-activated protein kinase kinases 1 and 2 (MEK1/2). MEK1/2 proteins are upstream regulators of the extracellular signal-related kinase (ERK) pathway. Both MEK and ERK are critical components of the RAS-regulated RAF-MEK-ERK pathway, which is often activated in different types of cancers.

    In genetically modified mouse models of NF1 that generate neurofibromas that recapitulate the genotype and phenotype of human NF1, oral dosing of selumetinib inhibited ERK phosphorylation, and reduced neurofibroma numbers, volume, and proliferation.

    12.2 Pharmacodynamics

    The exposure-response relationship and time course of pharmacodynamic response for the safety and effectiveness of KOSELUGO have not been fully characterized.

    Cardiac Electrophysiology

    At a dose 1.5 times the maximum recommended dose, KOSELUGO does not prolong the QT/QTc interval to any clinically relevant extent.

    12.3 Pharmacokinetics

    At the recommended dosage of 25 mg/m2 twice daily in pediatric patients (2 to ≤ 18 years old), the mean maximum plasma concentration (Cmax) (coefficient of variation [CV%]) following the first dose and at steady state was 731 (62%) ng/mL and 798 (52%) ng/mL, respectively. The mean area under the plasma drug concentration curve (AUC0-12h) following the first dose was 2009 (35%) ngh/mL and the AUC0-6h at steady state was 1958 (41%) ngh/mL. Selumetinib AUC and Cmax increases proportionally over a dose range from 20 mg/m2 to 30 mg/m2 (0.8 to 1.2 times the recommended dose). The accumulation was 1.1-fold following administration of KOSELUGO 25 mg/m2 twice daily.

    Absorption

    The mean absolute oral bioavailability of selumetinib was 62% in healthy adults. The median time to peak plasma concentrations (Tmax) at steady-state in pediatric patients was 1 to 1.5 hours.

    Effect of Food

    Mean Cmax and AUC of selumetinib decreased by 50% and 16%, respectively, following a high-fat meal (1000 calories, 50% fat) in healthy adults administered a single-dose of 75 mg (1.5 times the approved maximum recommended dosage). Tmax was delayed by approximately 1.5 hours following a high-fat meal.

    Selumetinib Cmax and AUC decreased by 60% and 38%, respectively, following a low-fat meal (400 calories, 25% fat) in healthy adults administered a single-dose of 50 mg. Tmax was delayed by approximately 0.9 hours following a low-fat meal.

    Distribution

    The mean apparent volume of distribution at steady state (Vss) of selumetinib across a dose range of 20 mg/m2 to 30 mg/m2 (0.8 to 1.2 times the recommended dosage) ranged from 78 L to 171 L in pediatric patients.

    The plasma protein binding was 98.4% in humans in vitro. Selumetinib binds to serum albumin (96%) and α-1 acid glycoprotein (< 35%).

    Elimination

    In pediatric patients, selumetinib had an apparent oral clearance (CL/F) of 8.8 L/hr and a mean elimination half-life of approximately 6.2 hours following a dose of 25 mg/m2.

    Metabolism

    Selumetinib is primarily metabolized by CYP3A4 and to a lesser extent by CYP2C19, CYP1A2, CYP2C9, CYP2E1, and CYP3A5. Selumetinib also undergoes glucuronidation by UGT1A1 and UGT1A3. It is estimated that 56% of the observed intrinsic clearance of selumetinib could be attributed to CYP metabolism and about 29% attributed to direct glucuronidation by UGT enzymes in vitro. The active metabolite, N-desmethyl selumetinib, is generated by CYP2C19 and CYP1A2 with additional contribution by CYP2C9 and CYP2A6, and metabolized through the same routes as selumetinib.

    N-desmethyl selumetinib represents less than 10% of selumetinib levels in human plasma, but is approximately 3 to 5 times more potent than the parent compound, contributing to about 21% to 35% of the overall pharmacologic activity.

    Excretion

    After a single oral dose of radiolabeled selumetinib 75 mg (1.5 times the recommended dose) to healthy adults, 59% of the dose was recovered in feces (19% as unchanged) and 33% in urine (< 1% as parent).

    Specific Populations

    Racial or Ethnic Groups

    No clinically meaningful effect on the pharmacokinetics of selumetinib or N-desmethyl selumetinib were observed based on race (White, Asian, Black).

    Patients with Renal Impairment

    Following administration of a single dose of 50 mg, selumetinib exposures were similar in subjects with end stage renal disease (CLcr < 15 mL/min) who required dialysis compared to subjects with normal renal function (CLcr ≥ 90 mL/min).

    Patients with Hepatic Impairment

    Following administration of a single-dose of selumetinib, dose normalized total AUC0-INF decreased by 14% in subjects with mild hepatic impairment (Child-Pugh A), and increased by 59% in subjects with moderate hepatic impairment (Child-Pugh B) and by 57% in subjects with severe hepatic impairment (Child-Pugh class C) compared to subjects with normal hepatic function. Selumetinib unbound AUC0-INF decreased by 31% in subjects with mild hepatic impairment (Child-Pugh A), and increased by 41% in subjects with moderate hepatic impairment (Child-Pugh B), and 3.2-fold in subjects with severe hepatic impairment (Child-Pugh C) compared to subjects with normal hepatic function.

    Drug Interaction Studies

    Clinical Studies and Model-Informed Approaches

    Effect of Strong or Moderate CYP3A4 Inhibitors: Concomitant use of itraconazole (strong CYP3A4 inhibitor) increased selumetinib AUC by 49% and Cmax by 19%. Concomitant use of erythromycin (moderate CYP3A4 inhibitor) is predicted to increase selumetinib AUC by 41% and Cmax by 23%.

    Effect of Fluconazole: Concomitant use of fluconazole (strong CYP2C19 inhibitor and moderate CYP3A4 inhibitor) increased selumetinib AUC by 53% and Cmax by 26%.

    Effect of Strong or Moderate CYP3A4 Inducers: Concomitant use of rifampicin (strong CYP3A4 inducer) decreased selumetinib AUC by 51% and Cmax by 26%. Concomitant use of efavirenz (moderate CYP3A4 inducer) is predicted to decrease selumetinib AUC by 38% and Cmax by 22%.

    In Vitro Studies

    CYP Enzymes: Selumetinib does not inhibit CYP1A2, CYP2A6, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP3A4, or CYP2E1. Selumetinib does not induce CYP3A4, CYP1A2, or CYP2B6.

    Transporter Systems: Selumetinib does not inhibit breast cancer resistance protein (BCRP), P-glycoprotein (P-gp), OATP1B1, OATP1B3, OCT2, OAT1, OAT3, MATE1, or MATE2K transporters.

    Selumetinib is a substrate of BCRP and P-gp transporters.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    Carcinogenicity

    Selumetinib was not carcinogenic in a 6-month study in rasH2 transgenic mice at exposures 24 times (males) and 36 times (females) and in 2-year carcinogenicity study in rats at exposures 20 times (male) and 15 times the human exposure (AUC) at the clinical dose of 25 mg/m2.

    Mutagenicity

    Selumetinib was not mutagenic or clastogenic in vitro. Selumetinib did result in an increase in micronucleated immature erythrocytes (chromosome aberrations) in mouse micronucleus studies, predominantly via an aneugenic mode of action, but at doses > 160 mg/kg (~38 times the human Cmax at the clinical dose of 25 mg/m2).

    Impairment of Fertility

    In a 6-month mouse study, selumetinib did not affect male mating performance at any dose up to 20 mg/kg twice daily (approximately 33 times the human exposure based on AUC at the clinical dose of 25 mg/m2 twice daily). In female mice exposed to selumetinib at 12.5 mg/kg twice daily, mating performance and fertility were not affected. The NOAEL for both maternal toxicity and effects on reproductive performance was 2.5 mg/kg twice daily (approximately 5 times the human exposure based on AUC at the clinical dose of 25 mg/m2 twice daily).

    13.2 Animal Toxicology and/or Pharmacology

    In a 26-week repeat-dose toxicology study, selumetinib at a dose of 20 mg/kg (approximately 33 times the human exposure based on AUC at the clinical dose of 25 mg/m2 twice daily) led to significant urinary tract obstruction as well as inflammation and luminal hemorrhage of the urethra leading to early death in male mice.

  • 14 CLINICAL STUDIES

    14.1 Neurofibromatosis Type 1 (NF1) with Inoperable Plexiform Neurofibromas (PN)

    The efficacy of KOSELUGO was evaluated in SPRINT Phase II Stratum 1, an open-label, multicenter, single arm trial (NCT01362803). Eligible patients were required to have NF1 with inoperable PN, defined as a PN that could not be completely removed without risk for substantial morbidity due to encasement of, or close proximity to, vital structures, invasiveness, or high vascularity of the PN. Patients were also required to have significant morbidity related to the target PN. Morbidities that were present in ≥ 20% of patients included disfigurement, motor dysfunction, pain, airway dysfunction, visual impairment, and bladder/bowel dysfunction. Patients received KOSELUGO 25 mg/m2 orally twice daily until disease progression or unacceptable toxicity.

    The major efficacy outcome measure was overall response rate (ORR), defined as the percentage of patients with complete response (defined as disappearance of the target PN) or confirmed partial response (defined as ≥ 20% reduction in PN volume confirmed at a subsequent tumor assessment within 3-6 months). The target PN, defined as the PN that caused relevant clinical symptoms or complications (PN-related morbidities), was evaluated for response rate using centrally read volumetric magnetic resonance imaging (MRI) analysis per Response Evaluation in Neurofibromatosis and Schwannomatosis (REiNS) criteria. Tumor response was evaluated at baseline and while on treatment after every 4 cycles for 2 years, and then every 6 cycles. An additional efficacy outcome measure was duration of response (DoR).

    A total of 50 pediatric patients received KOSELUGO. The median age was 10.2 years (range 3.5 to 17.4 years); 60% were male; and 84% were White, 8% were Black and 2% were Asian.

    Efficacy results are provided in Table 8. The median time to onset of response was 7.2 months (range: 3.3 months to 1.6 years).
