MEK162 for Patients With RAS/RAF/MEK Activated Tumors

ORR: percentage of participants with a best overall response (BOR) of CR or PR as assessed per RECIST version 1.1. BOR: the best response recorded from the start of the treatment until disease progression (PD). CR: disappearance of all target and non-target lesions, normalization of tumor marker level, pathological lymph nodes assigned as target or non-target lesions must have a reduction in short axis to less than <10 mm; PR: at least a 30 % decrease in sum of diameter of all target lesions, taking as reference the baseline sum of diameters; PD: at least a 20% increase in sum of diameter of all measured target lesions, taking as reference smallest sum of diameter of all target lesions recorded at or after baseline, sum was also an absolute increase of at least 5 mm. Unequivocal progression of existing non-target lesions. Appearance of >=1 new target or non-target lesions.

ORR: percentage of participants with sCR, CR, VGPR or PR. For hematologic tumors (multiple myeloma), sCR: negative immunofixation on the serum, urine, disappearance of any soft tissue plasmacytomas and <5% plasma cells in bone marrow plus normal FLC ratio and absence of clonal cells in bone marrow by immunohistochemistry or immunofluorescence; CR: CR: negative immunofixation on the serum, urine, disappearance of any soft tissue, plasmacytomas and <5% plasma cells in bone marrow; VGPR: serum and urine M-component detectable by immunofixation but not on electrophoresis or greater than equal to >=90% reduction in serum M-component plus urine M-component <100 mg per 24hour (hr); PR: >50% reduction of serum M-protein and reduction in 24 hr urinary M-protein by >90% or to <200 mg/24 hr.

ORR: participants with complete remission (CR), CR with incomplete blood count recovery (CRi), partial remission (PR) and no resposne for at least 16 weeks. For hematologic tumors (acute myeloid leukemia); CR: as bone marrow- < 5% blasts, no blasts with auer rods, peripheral blood- neutrophils ≥1.0*10^9/L and/or platelets ≥100*10^9/L, ≤1% blasts, no evidence of extramedullary disease (such as CNS or soft tissue involvement), transfusion independent; CRi: all the CR criteria were involved but platelet and neutrophil transfusions were also allowed; PR: bone marrow- 50% or greater decrease (absolute range 5-25% blasts), < 5% of blasts contain auer rods, peripheral blood- neutrophils <1.0*10^9/L and/or platelets <100*10^9/L, no evidence of extramedullary disease.

PFS was defined as the time from the date of first dose to the date of first documented PD or relapse or death due to any cause. PD: 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. Unequivocal progression of existing non-target lesions. Appearance of >=1 new target or non-target lesions was also considered progression. PFS data was censored at date of last adequate tumor assessment.

OS was defined as the time from the date of first dose to the date of death due to any cause. If a participant was not known to have died, survival time was censored at the date of last contact.

DOR was defined as the time from the first documented response (CR or PR) to the date of first documented disease progression, relapse or death due to any cause. As per RECIST 1.1, CR: disappearance of all target and non-target lesions, normalization of tumor marker level, pathological lymph nodes assigned as target or non-target lesions must have a reduction in short axis to <10 mm; PR: at least a 30% decrease in sum of diameter of all target lesions, taking as reference the baseline sum of diameters; PD: at least a 20% increase in sum of diameter of all measured target lesions, taking as reference smallest sum of diameter of all target lesions recorded at or after baseline, sum was also an absolute increase of at least 5 mm. Unequivocal progression of existing non-target lesions. Appearance of >=1 new target or non-target lesions. The DOR was determined only in participants whose best response was PR or greater.

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. Treatment-emergent adverse events were defined as new or worsening events that were collected from first study treatment date to last treatment date +30 days. AEs of all grades were reported.

Vital signs included hypertension, hypotension and weight decreased were reported. 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. Participants with grade 3 or higher vital sign abnormality are reported.

ECG abnormalities criteria included: 1) QTc interval adjusted according to Bazett formula (QTcF) in millisecond (msec): greater than equal to (>=) 450 to less than (<) 480, >=480 to <500, >=500, increase from baseline >=30, increase from baseline >=60; 2) QTc interval adjusted according to Fridericia formula (QTcB) (msec): >=450 to <480, >=480 to <500, >=500, increase from baseline >=30, increase from baseline >=60. 3) QT (msec): >=450 to <480, >=480 to <500, >=500, increase from baseline >=30, increase from baseline >=60.

Laboratory parameters included hematological and biochemistry parameters. Hematological parameters included neutrophils, platelets, prothrombin time, activated partial thromboplastin time, INR, fibrinogen. Number of participants with hematological abnormalities by grades (as per Common Terminology Criteria for Adverse Events (CTCAE version 4.03) were reported. Grade 1= mild; Grade 2= moderate; Grade 3= severe and Grade 4= life-threatening or disabling. Participants with a grade shift of 3 or more from baseline are reported in this outcome measure.

Laboratory parameters included hematological and biochemistry parameters. Biochemistry parameters included: creatinine, phosphorus, albumin, gamma-glutamyl transferase, aspartate transaminase, alanine aminotransferase, alkaline phosphatase, total bilirubin, uric acid, amylase, lipase, creatine kinase, total cholesterol and triglycerides. Number of participants with biochemistry test abnormalities by grades (CTCAE version 4.03) were reported. Grade 1= mild; Grade 2= moderate; Grade 3= severe and Grade 4= life-threatening or disabling. Participants with a grade shift of 3 or more from baseline are reported in this outcome measure.

Number of Participants With Shift From Baseline in Cardiac Imaging were reported.
