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

TerminatedPhase 1

Sponsor: Seagen, a wholly owned subsidiary of Pfizer

Conditions: Cutaneous Melanoma, Non-small Cell Lung Cancer, Colorectal Neoplasms, Pancreatic Neoplasms, Mesothelioma

Interventions: PF-08046049

Countries: United States, Canada, France, Germany, Switzerland, United Kingdom

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.

  * 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
