This trial will look at a drug called SGN-B6A to find out whether it is safe for people who have solid tumors. It will study SGN-B6A to find out what its side effects are. A side effect is anything the drug does besides treating cancer. It will also study whether SGN-B6A works to treat solid tumors.

The study will have two parts. Part A of the study will find out how much SGN-B6A should be given to participants. Part B will use the dose found in Part A to find out how safe SGN-B6A is and if it works to treat solid tumors.

Inclusion Criteria

Disease indication
Participants must have histologically or cytologically confirmed metastatic or unresectable solid malignancy within one of the tumor types listed below (dependent on study part). Participants must have disease that is relapsed or refractory or be intolerant to standard-of-care therapies and should have no appropriate standard-of-care therapeutic option
Non-small cell lung cancer (NSCLC)
Head and neck squamous cell cancer (HNSCC)
Advanced HER2-negative breast cancer
Esophageal squamous cell carcinoma (ESCC)
Cutaneous squamous cell cancer (cSCC)
Exocrine pancreatic adenocarcinoma
Bladder cancer
Cervical cancer
Gastric cancer
High grade serous ovarian cancer (HGSOC)
Participants enrolled in the following study parts should have a tumor site accessible for biopsy and agree to biopsy as follows
Disease-specific expansion cohorts, participant 13 onwards: pre-treatment biopsy
Biology expansion cohort: pre-treatment biopsy and additional on-treatment biopsy during Cycle 1
An Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1
Measurable disease per the RECIST v1.1 at baseline

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
are clinically stable for at least 4 weeks prior to study entry after brain metastasis treatment
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 first dose of study drug
Carcinomatous meningitis
Previous receipt of an MMAE-containing agent or an agent targeting integrin beta-6
Pre-existing neuropathy Grade 2 or greater per the National Cancer Institute's Common Terminology Criteria for Adverse Events, version 5.0 (NCI CTCAE v5.0)
Any uncontrolled Grade 3 or higher (per NCI CTCAE v5.0) viral, bacterial, or fungal infection within 2 weeks prior to the first dose of SGN-B6A
Routine antimicrobial prophylaxis is permitted
