Phase 1: Number of Participants with Dose Limiting Toxicities (DLT) |
DLT will be defined as any of the TEAEs that occur during Cycle 1 and are considered by the investigator to be at least possibly related to modakafusp alfa. Toxicity will be evaluated according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Version 5.0. |

|
Primary |
Phase 1: Number of Participants Reporting one or More Treatment-emergent Adverse Events (TEAEs) and Per Severity |
An adverse event (AE) is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (e.g., a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. A TEAE is defined as an adverse event with an onset that occurs after receiving study drug. Severity grades for TEAEs will be evaluated as per the NCI CTCAE Version 5.0. |
Up to 60 months |
