NCT05208762

Brief Summary

This study will test the safety of a drug called PF-08046054/SGN-PDL1V alone and with pembrolizumab 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 five parts. Parts A and B of the study will find out how much PF-08046054/SGN- PDL1V should be given to participants. Part C will use the dose found in Parts A and B to find out how safe PF-08046054/SGN-PDL1V is and if it works to treat solid tumor cancers. In Part D and E, participants will be given PF-08046054/SGN-PDL1V with pembrolizumab to find out how safe this combination is and if it works to treat solid tumor cancers.

  • Head and neck squamous cell carcinoma (HNSCC) (except nasopharyngeal cancer)
  • Esophageal squamous cell carcinoma (SCC)
  • Triple negative breast cancer (TNBC)
  • Participants must have disease that is relapsed or refractory, that has progressed on approved therapies, be intolerant to or refused such therapies, or such and therapies are contraindicated and in the judgement of the investigator, should have no appropriate SoC therapeutic option

  • HNSCC
  • Participants with HNSCC must have histologically or cytologically-confirmed HNSCC
  • NSCLC
  • Participants must have histologically or cytologically-confirmed NSCLC. Participants with SCC and non--SCC histology are eligible. Note: Participants with a neuroendocrine component or histology are not eligible.

  • Have no new or enlarging brain metastases
  • And are off of corticosteroids prescribed for symptoms associate with brain metastases for at least 7 days prior to first dose of study treatment
  • Lepto-meningeal disease
