Summary
Brief summary
The study will evaluate the safety, pharmacokinetics and pharmacodynamics of increasing doses
of PF-06804103 in patients with HER2 positive and negative breast and gastric cancer (HER2
positive only and gastric were studied in Part 1A only). The study will expand to look at
selected doses in patients with HER2 positive and negative breast cancer.
