The purpose of this study was to estimate the maximum tolerated dose and/or recommended dose for expansion of LDK378 as a single agent, assess safety, tolerability and anti-tumor activity and characterize single and multiple-dose pharmacokinetics when administered orally to pediatric patients with ALK-activated tumors, with and without food.
LDK378 is a novel inhibitor of ALK that is active in a broad range of ALK-activated tumor models, including models driven by mutated versions of ALK known to be resistant to crizotinib, and by ALK gene amplification. The primary purpose of this study was to determine the maximum tolerated dose and/or recommended dose for expansion in pediatric patients, and to delineate a clinical dose to be used in any future pediatric studies, with and without food. This study also assessed the safety, tolerability, PK and preliminary evidence of antitumor activity of LDK378 in pediatric patients with neuroblastoma, and other ALK-activated tumors. Fasted cohort: each daily dose of LDK378 (including days which involved PK blood sampling) was taken at least 2 hours after last meal \& subjects did not eat until 1 hour after LDK378 was taken. Each daily dose of LDK378 was taken with 1-2 tablespoons (15-30 mL) of an appropriate food (such as applesauce or non-fat yogurt) \& a glass of water Fed cohort: each daily dose of LDK378 (including days which involved PK blood sampling) was taken with, or within 30 minutes after finishing a low-fat light snack containing 100-300 calories \& 1.5-2 grams of fat.

LDK378 is a capsule taken by mouth, contents can be mixed with food for pediatric patients or mixed with water and given via nasogastric/gastric (NG/G) tube. For patients in fasted group: 1-2 tablespoons (15-30 mL) of an appropriate food such as apple sauce or non-fat yogurt and a glass of water were allowed. For patients in the fed cohort: LDK378 was taken with, or within 30 minutes after finishing a low-fat light snack containing 100-300 calories and 1.5-2 grams of fat.

Incidence Rate of Dose Limiting Toxicities (DLTs) Occurring During First Cycle of Treatment
A DLT is defined as an adverse event or abnormal laboratory value assessed as unrelated to disease, disease progression, inter-current illness, or concomitant therapies that occurs within the first 21 days of treatment with LDK378 and meets a specified defined criteria. A participant with multiple occurrences of DLTs under one treatment is counted only once in the Adverse Event category for that treatment. A participant with multiple DLTs within a primary system organ class is counted only once in the total row.
Time frame: up to day 21 after the patient's first dose; cycle = within the first 21 days of patient's first dose
Summary of Best Overall Response by Overall Response Rate (ORR) Per Investigator Assessment
ORR is the percentage of participants with a best overall response of complete response (CR) or partial response (PR). ORR was assessed per Investigator as per RECIST 1.1 in participants with neuroblastoma and other solid tumors, and by International Working Group (IWG) criteria in patients with lymphoma. Per RECIST 1.1 (for neuroblastoma \& other solid tumors): CR: disappearance of all non-nodal target lesions. In addition, any pathological lymph nodes assigned as target lesions must have a reduction in short axis to \< 10 mm. PR: at least a 30% decrease in the sum of diameter of all target lesion, taking as reference the baseline sum diameters. Per IWG criteria (for patients with lymphoma): CR: normalization of all index nodal lesions or complete disappearance of all index extranodal lesions. PR: at least 50% decrease from baseline in the sum of diameters of all index lesions.
Time frame: 30 months
Duration of Response (DoR) Per Investigator Assessment
DOR is defined as the time from first documented response (PR or CR) to the date of first documented disease progression (PD) or death due to any cause. DOR was assessed per Investigator as per RECIST 1.1 in participants with neuroblastoma and other solid tumors, and by International Working Group (IWG) criteria in patients with lymphoma. Per RECIST 1.1 (for neuroblastoma \& other solid tumors): CR: disappearance of all non-nodal target lesions. In addition, any pathological lymph nodes assigned as target lesions must have a reduction in short axis to \< 10 mm. PR: at least a 30% decrease in the sum of diameter of all target lesion, taking as reference the baseline sum diameters. Per IWG criteria (for patients with lymphoma): CR: normalization of all index nodal lesions or complete disappearance of all index extranodal lesions. PR: at least 50% decrease from baseline in the sum of diameters of all index lesions.

Progression Free Survival (PFS) Based on Investigator Assessment
PFS is the time from date of randomization/start of treatment to the date of event defined as the first documented progression or death due to any cause. PFS was assessed per Investigator as per RECIST 1.1 in participants with neuroblastoma and other solid tumors, and by International Working Group (IWG) criteria in patients with lymphoma. Per RECIST 1.1 (for neuroblastoma \& other solid tumors): CR: disappearance of all non-nodal target lesions. In addition, any pathological lymph nodes assigned as target lesions must have a reduction in short axis to \< 10 mm. PR: at least a 30% decrease in the sum of diameter of all target lesion, taking as reference the baseline sum diameters. Per IWG criteria (for patients with lymphoma): CR: normalization of all index nodal lesions or complete disappearance of all index extranodal lesions. PR: at least 50% decrease from baseline in the sum of diameters of all index lesions.
