This is a Phase 1/2 study of PF-06747775 as a single agent and in combination with other cancer treatments in patients with advanced EGFRm NSCLC. The overall clinical study consists of a Phase 1 single agent dose-escalation and expansion part to determine the RP2D of PF-06747775 single agent in patients with previously-treated EGFRm NSCLC followed by sequential evaluations of PF-06747775 at the RP2D in 3 different clinical scenarios as detailed below: - Cohort 1: Phase 2 evaluation of PF-06747775 as a single agent in previously untreated patients with advanced EGFRm NSCLC, - Cohort 2: Phase 1b single arm evaluation of PF-06747775 in combination with palbociclib (Cohort 2A) followed by Phase 2 randomized evaluation of PF 06747775 in combination with palbociclib vs PF-06747775 single agent (Cohort 2B) in previously-treated patients with EGFRm NSCLC with a secondary T790M mutation (del 19 and T790M or L858R and T790M), and - Cohort 3: Phase 1b evaluation of PF-06747775 in combination with avelumab in previously-treated patients with EGFRm NSCLC with a secondary T790M mutation (del 19 and T790M or L858R and T790M).
Name: PF-06747775
Type: DrugCohort 1 Cohort 2A Cohort 2B Cohort 3
Name: Palbociclib
Type: DrugCohort 2A Cohort 2B
Name: Avelumab
Type: DrugCohort 3
Description: The target probability of DLT at MTD will be 30%
Measure: Phase 1 Primary Endpoint - Number of patients with dose limiting toxicities during Phase 1 Time: 21 daysDescription: Cohort 1 is an evaluation of PF 06747775 single agent at RP2D Cohorts 2A and 3 will determine the RP2D of PF-06747775 in combination with either palbociclib or avelumab, respectively, based on safety and tolerability. Determination of the RP2D will be performed using the mTPI design. For Cohort 2A, after determination of the RP2D for the PF-06747775 and palbociclib combination, a randomized evaluation of the combination vs PF-06747775 single agent (2:1 ratio) will be initiated (Cohort 2B). For Cohort 3, after determination of the RP2D for the PF-06747775 and avelumab combination, the dose level will be expanded to enroll an overall total of approximately 20 patients to further explore the safety, PK, and antitumor activity of the combination.
Measure: Phase 1b/2 - Cohort 1 = confirmed OR per RECIST; Cohort 2A = Cycle 2 DLT; Cohort 2B = PFS and Cohort 3 = Cycle 1 DLT Time: Cohorts 1, 2A and 2B = 21 day cycles and Cohort 3 = 28 day cyclesDescription: Number of patients with OR based assessment of confirmed CR or PR according to RECIST. CR are those that persist on repeat imaging at least 4 weeks after the initial documentation of response. PR are those that are greater or equal to a 30% decrease ( per RECIST) under the baseline of the sum of diameters of all target measurable disease
Measure: Phase 1: Secondary Endpoint - Number of patients with Objective Response (OR) Time: Time from first dose of study drug until OR of CR or PR up to 24 monthsDescription: PFS (cohort 1, 2A and 3) ORR (cohort 2A, 2B and 3) DOR (All cohorts)
Measure: Phase 1b/2 Time: Time from first dose of study drug until Disease Progression or death (whichever first) up to 24 monthsAllocation: Randomized
