A Phase 1 dose escalation study evaluating safety, tolerability and pharmacokinetics of PF-06952229 in adult patients with advanced solid tumors.
A PHASE 1 DOSE ESCALATION STUDY EVALUATING SAFETY, TOLERABILITY AND PHARMACOKINETICS OF PF-06952229 IN ADULT PATIENTS WITH ADVANCED SOLID TUMORS
This is a Phase 1, open label, multi center, multiple dose, dose escalation and expansion, safety, tolerability, PK, and pharmacodynamics study of PF 06952229 in previously treated patients with advanced or metastatic cancer that is known to have high TGFbeta signatures and EMT expression.
This trial includes 2 parts. Part 1 is a a monotherapy dose escalation phase and Part 2 arms A and B is the dose escalation expansion phase. Part 2 Arm A combines PF-06952229 with palbociclib and letrozole in HR+HER advanced or metastatic breast cancer. Part 2 Arm B combines PF-06952229 with enzalutamide in castration resistant prostate cancer (CRPC).
