Phase 2 Study of MGCD265 in Patients With Non-Small Cell Lung Cancer With Activating Genetic Alterations in MET

Objective disease response is defined as the percent of patients documented by investigator assessment to have a confirmed Complete Response (CR) or Partial Response (PR) in accordance with the Response Evaluation Criteria in Solid Tumors (RECIST 1.1) for target and non-target lesions as assessed by CT or MRI. CR is defined as complete disappearance of all target lesions with the exception of nodal disease; PR is defined as >=30% decrease under baseline of the sum of diameters of all target measurable lesions; Stable Disease (SD) is concluded when the response does not qualify for CR, PR or Progression; Progressive Disease (PD) is defined as a 20% increase in the sum of diameters of target measurable lesions above the smallest sum observed with a minimum absolute increase of 5 mm, or unequivocal progression of pre-existing non-target lesions.

Duration of Response (DR) will be defined as the time from date of the first documentation of objective tumor response (CR or PR) to the first documentation of Objective Progression of Disease (PD) or to death due to any cause in the absence of documented PD.

Progression-free survival (PFS) will be defined as the time from date of first study treatment to first PD or death due to any cause in the absence of documented PD. Per RECIST 1.1, Progressive Disease (PD) is defined as a 20% increase in the sum of diameters of target measurable lesions above the smallest sum observed (over baseline if no decrease in the sum is observed during therapy) with a minimum absolute increase of 5 mm, or unequivocal progression of pre-existing non-target lesions.

1-Year Survival will be defined as the probability of survival at 1 year after the first dose.

Overall Survival will be defined as the time from date of first study treatment to death due to any cause

Number of patients experiencing treatment-emergent adverse events.

Blood samples for PK assessment were to be taken on Cycle 1, Day 1 and Day 15 at pre-dose and at 2 hours (1-3 hours) and 6 hours (4-8 hours) post-dose. The number of patients reported for each PK parameter was dependent on the actual number of blood samples collected post-dose.

Blood samples for PK assessment were to be taken on Cycle 1, Day 1 and Day 15 at pre-dose and at 2 hours (1-3 hours) and 6 hours (4-8 hours) post-dose. On Cycle 2, samples were collected on Day 1 and Day 15 at pre-dose and at 6 hours post-dose (4-8 hours). Note: Assessment of Cmax and Tmax are limited by the sparse blood sampling schedule post dose (i.e., only 2 blood draws post-dose in Cycle 1 and only 1 sample collected post-dose in Cycle 2). The number of patients reported for each PK parameter was dependent on the actual number of blood samples collected post-dose.

Only a sub-set of patients had different molecular techniques completed, therefore a correlation analysis was not performed. Patients with positive identification by two different analytical techniques are tabulated for MET Activating Mutations.
