This study will test the safety of a drug called SGN-PDL1V in participants with solid tumors.
It will also study the side effects of this drug. A side effect is anything a drug does to
your body besides treating your disease.
Participants will have solid tumor cancer that has spread through the body (metastatic) or
cannot be removed with surgery (unresectable).
This study will have three parts. Parts A and B of the study will find out how much SGN-
PDL1V should be given to participants. Part C will use the dose found in Parts A and B to
find out how safe SGN-PDL1V is and if it works to treat solid tumor cancers.
