LGX818LGX818LGX818 will be dosed on a flat scale of 300 mg (e.g., 3 x 100 mg capsules) once daily on a continuous dosing cycle. A complete treatment cycle is defined as 28 days. There will be no breaks between dosing cycles.
Primary Outcome Measures
NameTimeMethod
Clinical Benefit Rate (CBR) for Solid Tumors as Per Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1Up to 13.3 months

CBR for solid tumors was defined as percentage of participants with complete response (CR) or partial response (PR), or stable disease (SD) for greater than or equal to (\>=) 16 weeks. As per RECIST v1.1, CR was defined as disappearance of all target and non-target lesions and normalization of tumor markers. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to less than (\<) 10 millimeter (mm). PR was defined as at least a 30 percent (%) decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. SD was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease, taking as reference the smallest sum diameters while on study. PD was defined as at least a 20% increase in the sum of diameter of all measured target lesions, taking as reference the smallest sum of diameter of all target lesions recorded at or after baseline.

Secondary Outcome Measures
NameTimeMethod
Overall Response Rate (ORR) for Solid Tumors as Per RECIST Version 1.1From the first dose study treatment until the first documented CR or PR (maximum up to 13.3 months)

ORR for solid tumors was defined as the percentage of participants achieving an overall best response of CR or PR as assessed per RECIST version 1.1. CR was defined as disappearance of all target and non-target lesions and normalization of tumor markers. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. PR was defined as least a 30 % decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

Progression-Free Survival (PFS) for Solid Tumors as Per RECIST Version 1.1From the date of first dose until the first documentation of PD, relapse, censored date or death, whichever occurred first (maximum up to 13.3 months)

PFS for solid tumors was defined as the time from the date of first dose of study drug to the date of first documented disease progression (PD) or relapse or death due to any cause within 30 days of the last dose. PD was defined as at least a 20% increase in the sum of diameter of all measured target lesions, taking as reference the smallest sum of diameter of all target lesions recorded at or after baseline. Participants who had no event were censored at the date of last adequate tumor assessment.

Overall Survival (OS) for Solid TumorsFrom date of the first dose until the date of death, censored date (maximum up to 13.3 months)

OS for solid tumors was defined as the time from the date of first dose of study drug to the date of death due to any cause. For participants who were alive at the time of analysis, the data was censored at the date of last contact.

Duration of Response (DOR) for Solid Tumors as Per RECIST Version 1.1From first documentation of response to first documentation of PD or relapse or death (maximum up to 13.3 months)

DOR for solid tumors was defined as the time from the first documented response (CR or PR) to the date of first documented PD or relapse or death due to any cause, whichever occurred first. As per RECIST v1.1, CR was defined as disappearance of all target and non-target lesions and normalization of tumor markers. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. PR was defined as least a 30 % decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. PD was defined as at least a 20% increase in the sum of diameter of all measured target lesions, taking as reference the smallest sum of diameter of all target lesions recorded at or after baseline. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm.

Number of Participants With Treatment Emergent Adverse Events (TEAEs) Graded According to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), Version 4.03Screening up to 30 days after the last dose of study treatment (maximum up to 13.3 months)

Adverse event (AE) was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. As per NCI-CTCAE version 4.03, severity was graded as Grade 1: asymptomatic/mild symptoms, clinical/diagnostic observations only, intervention not indicated; Grade 2: moderate, minimal, local/noninvasive intervention indicated, limiting age-appropriate instrumental activities of daily life (ADL); Grade 3: severe/medically significant but not immediately life-threatening, hospitalization/prolongation of existing hospitalization indicated, disabling, limiting self-care ADL; Grade 4: life-threatening consequence, urgent intervention indicated. TEAE was defined as event with onset dates occurring during the on-treatment period. CTCAE Grade 5 (death) was not used in this study.

Number of Participants With Shifts From Baseline in Hematology and Serum Chemistry Laboratory AbnormalitiesBaseline up to maximum of 30 days after the last dose of study treatment (up to 13.3 months)

Number of participants with shifts from baseline in hematology and serum chemistry laboratory parameters, were graded and reported as low, normal and high as assessed by Common terminology criteria for adverse events (CTCAE) v4.03. 'Low' refers to participants with values that were below lower limit of normal with no observation above the upper limit of normal; 'High' refers to participants with values that were above the upper limit of normal with no observation below the lower limit of normal; 'Low and High' refers to participants with values that were below the lower limit of normal and values that were above the upper limit of normal.

Change From Baseline in QT Interval Corrected According to the Formula of Fridericia (QTcF), QT, QRS, and PR DurationBaseline, Day 15 of Cycle 1, 2, Day 1 of Cycle 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 (each cycle of 28 days), and End of treatment (up to 7 days after study treatment discontinuation)

Change from baseline in QTcF, QT, QRS, and PR duration were reported. QT interval is the time from electrocardiogram Q wave to the end of the T wave corresponding to electrical systole. QRS interval is the time from electrocardiogram Q wave to the end of the S wave, corresponding to ventricle depolarization. PR interval is the time between the beginning of the P wave and the start of the QRS interval, corresponding to the end of atrial depolarization and onset of ventricular depolarization.

Change From Baseline in Heart RateBaseline, Day 15 of Cycle 1, 2, Day 1 of Cycle 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 (each cycle of 28 days), and End of treatment (up to 7 days after study treatment discontinuation)
