A Study of PF-08046049/SGN-BB228 in Advanced Melanoma and Other Solid Tumors

Purpose

This study will test the safety of a drug called PF-08046049/SGN-BB228 in participants with melanoma and other solid tumors that are hard to treat or have spread through the body. It will also study the side effects of this drug. A side effect is anything a drug does to the body besides treating the disease. This study will have 3 parts. Parts A and B of the study will find out how much PF-08046049/SGN-BB228 should be given to participants. Part C will use the information from Parts A and B to see if PF-08046049/SGN-BB228 is safe and if it works to treat solid tumor cancers.

Exclusion Criteria

  • History of another malignancy within 3 years before the first dose of study drug, or any evidence of residual disease from a previously diagnosed malignancy. Exceptions are malignancies with a negligible risk of metastasis or death. - Active central nervous system metastases or leptomeningeal disease. Participants with previously treated brain metastases may participate provided they are: - clinically stable for at least 4 weeks prior to study entry after brain metastasis treatment, - they have no new or enlarging brain metastases, - and are off of corticosteroids prescribed for symptoms associated with brain metastases for at least 7 days prior to the first dose of study drug. - Prior therapies cannot include any drugs targeting CD228 or 4-1BB - Immunotherapy, biologics, and/or other approved or investigational antitumor treatment that is not completed 4 weeks prior to first dose of study drug, or within 2 weeks prior to the first dose of study drug if the underlying disease has progressed on treatment - Melanoma subtypes including acral, uveal, and mucosal are excluded
