Description:
This is a Phase 1, open label, multicenter, nonrandomized, multiple dose, safety,
tolerability, pharmacokinetic and pharmacodynamic study of PF-07220060 administered as a
single agent and then in combination with endocrine therapy.
In Part 1A, single escalating doses of PF-07220060 alone will be administered to determine
the maximum tolerated dose (MTD) and select the recommended phase 2 dose (RP2D). In Part 1B
and Part 1C, PF-07220060 will be administered in combination with 1 of 2 endocrine therapies
(letrozole and fulvestrant, respectively).
Part 1B and Part 1C may be enrolled and conducted in parallel at the completion of Part 1A.
