Full Title
A Phase 1 Study of SGN-B6A in Advanced Solid Tumors
This trial will look at a drug called sigvotatug vedotin (SGN-B6A) alone and with pembrolizumab, with or without chemotherapy, to find out whether it is safe for people who have solid tumors. It will study sigvotatug vedotin to find out what its side effects are. A side effect is anything the drug does besides treating cancer. It will also study whether sigvotatug vedotin works to treat solid tumors.
Study Treatment
The study will have four parts.
Part A of the study will find out how much sigvotatug vedotin should be given to participants.
Part B will use the dose found in Part A to find out how safe sigvotatug vedotin is and if it works to treat solid tumors.
Experimental: Part B: Dose expansion
sigvotatug vedotin monotherapy
Drug: sigvotatug vedotin
• Administered into the vein (IV; intravenously)
• Other Names: SGN-B6A
Part C of the study will find out how safe sigvotatug vedotin is in combination with these other drugs.
Experimental: Part C: sigvotatug vedotin combination therapy in NSCLC, HNSCC, ESCC
sigvotatug vedotin + pembrolizumab (Keytruda) +/- (carboplatin or cisplatin)
Drug: sigvotatug vedotin
• Administered into the vein (IV; intravenously)
• Other Names: SGN-B6A
Drug: pembrolizumab (Keytruda)
• 200mg every 3 weeks or 400mg every 6 weeks, given by IV
Drug: cisplatin
• 75 mg/m2 every 3 weeks, given by IV
Drug: carboplatin
• AUC 5 mg/mL per min every 3 weeks, given by IV
Part D will include people who have not received treatment. This part of the study will find out how safe sigvotatug vedotin is in combination with these other drugs and if these combinations work to treat solid tumors.
Experimental: Part D: sigvotatug vedotin combination therapy in 1L NSCLC
sigvotatug vedotin + pembrolizumab (Keytruda) +/- (carboplatin)
Drug: pembrolizumab (Keytruda) 200mg every 3 weeks or 400mg every 6 weeks, given by IV
Drug: carboplatin AUC 5 mg/mL per min every 3 weeks, given by IV
or
Experimental: Part D: sigvotatug vedotin combination therapy in 1L HNSCC

• Drug: pembrolizumab (Keytruda) 200mg every 3 weeks or 400mg every 6 weeks, given by IV
Plus cisplatin 75 mg/m2 every 3 weeks, given by IV
Or carboplatin AUC 5 mg/mL per min every 3 weeks, given by IV

Exclusion Criteria
• History of another malignancy within 3 years before 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.
• Known active central nervous system metastases. Participants with previously treated brain metastases may participate provided they:
