This study is seeking participants who have any of the following cancer types:

* non-small cell lung cancer

* kidney cancer
* head and neck cancer Participants will receive the study medicine PF-07921585 alone or in combination with another study medicine called sasanlimab at the study clinic.

PF-07921585 will be given as an infusion into a vein or as shots under the skin, once every 3 weeks. Sasanlimab will be given as shots under the skin, also once every 3 weeks.
