This study has two parts: Part 1 (dose escalation) and Part 2 (dose expansion). The purpose of Part 1 is to determine: What effects, good and/or bad, STRO-002 has on subjects and their disease The highest dose of STRO-002 that can be safely given to subjects using a pre-defined starting dose and rules for increasing the dose The dose of STRO-002 that has the best overall safety profile. This includes collection of side effects and measured amounts of STRO-002 in the blood at different time points, known as pharmacokinetics (PK) testing. This dose, the recommended phase 2 dose (RP2D), will be used in Part 2 of this study. Levels (if any) of antibodies in the blood which may arise in response to study drug known as anti-drug antibodies (ADA) During Part 2, subjects will be dosed at the applicable RP2D selected from Part 1 of the study. The purpose of Part 2 is to determine: What effects, good and/or bad, STRO-002 has on subjects including ADA as defined above How their cancer responds to treatment with STRO-002 The amount of STRO-002 in the blood at different times (PK) Key Eligibility
