Part 1: Percentage of Participants Reporting One or More Treatment Emergent Adverse Events (TEAEs)Primary· Up to 54.3 months in Part 1
An adverse event (AE) is defined as any untoward medical occurrence in a participants administered a pharmaceutical product; the untoward medical occurrence does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product whether or not it is related to the medicinal product. A TEAE is defined as any AE either reported for the first time or worsening of a pre-existing event after first dose of

Part 1: Number of Participants With Dose-limiting Toxicities (DLTs)Primary· Up to Cycle 1 (cycle length was 28 days for Schedule A, B and D; 21 days for Schedule C)
DLTs were evaluated as per National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), version 5.0. Nonhematologic TEAEs of NCI CTCAE Grade ≥3 clearly unrelated to the underlying disease and occurring during the first cycle were considered DLTs.

The main aims of this 3-part study are as follows:
Part 1: To determine any side effects from modakafusp alfa single treatment and how often they occur. The dose of modakafusp alfa will be increased a little at a time until the highest dose that does not cause harmful side effects is found.
Part 2: To assess clinical activity of one or more dosing schedules of modakafusp alfa alone in participants with relapsed/refractory multiple myeloma. Dexamethasone standard dose will be administered with one or more selected dose of modakafusp alfa in selected group of participants.
Part 3: To find the optimal dose with the more favorable risk-benefit profile of modakafusp alfa.
Participants will receive modakafusp alfa at one of two doses which will be given through a vein.
