PHASE 1/2A DOSE ESCALATION AND EXPANSION STUDY EVALUATING SAFETY, TOLERABILITY, PHARMACOKINETIC, PHARMACODYNAMICS AND ANTI-TUMOR ACTIVITY OF PF-06873600 AS A SINGLE AGENT AND IN COMBINATION WITH ENDOCRINE THERAPY

Open-label, multi-center, non-randomized, multiple dose, safety, tolerability,
pharmacokinetic, and pharmacodynamics and clinical activity study of PF-06873600 administered
as a single agent and then in combination with endocrine therapy. The study contains two
parts, a Part 1 single agent dose escalation and combination endocrine therapy dose finding
component and a Part 2 dose expansion as both a single agent and in combination with
endocrine therapy.

This is a Phase 1/2a, open-label, multi-center, non-randomized, multiple dose, safety,
tolerability, pharmacokinetic, and pharmacodynamic study of PF-06873600 administered as a
single agent in sequential dose levels and then in combination with endocrine therapy. In
Part 1A, successive cohorts of patients will receive escalating doses of PF-06873600 and then
in dose finding (Part 1B) with PF-06873600 in combination with endocrine therapy (ET). This
study contains 2 parts, dose escalation with single agent (Part 1A) and then dose finding
with PF-06873600 in combination with endocrine therapy (Part 1B) followed by dose expansion
arms as a single agent and PF-06873600 in combination with endocrine therapy (Part 2).
