This is a study to evaluate the safety and preliminary anti-tumor activity of STRO-004 in adults with metastatic cancer. This study includes 3 parts:
* Part 1A is a dose escalation study of STRO-004 monotherapy in selected tumor types known to commonly express Tissue Factor (TF). * Part 1B is a cohort expansion in 1 or more types of cancer to further evaluate a STRO-004 monotherapy dose, determine the best dose for use in later phases, and examine anti-tumor activity. * Part 1C is a dose escalation of STRO-004 combined with pembrolizumab to determine tolerability and preliminary anti-tumor activity of both drugs used together.
