What was measured

An adverse event (AE) was any untoward medical occurrence in a participant/ clinical investigational participant administered a medicinal product and which does not necessarily have a causal relationship with this treatment. TEAEs were defined as newly occurring (not present at baseline)/worsening after first dose of investigational product (IP). TESAEs were any untoward medical occurrence at any dose that: suspected to cause death; life-threatening; required hospitalization; persistent/significant disability/incapacity \& may cause congenital anomaly/birth defect. Treatment related TEAEs were related to study treatment and relatedness was judged by investigator. TEAEs were graded according to National Cancer Institute, Common Terminology Criteria for Adverse Events (NCI-CTCAE) Version (v) 4.03 (grade 1= mild, grade 2= moderate, grade 3= severe and grade 4= life-threatening).

Analysis population: All treated participants analysis set included all treated participants who received any amount of SEA-BCMA.

Groups in this outcome

Part A: SEA-BCMA 100mg

Participants received SEA-BCMA 100 mg as a monotherapy q2wk IV on Day 1 and 15 of each 28- day cycle. Participants received treatment until disease progression, unacceptable toxicity, withdrawal of consent, death, or study termination, whichever occurs first.

Part A: SEA-BCMA 200mg

Participants received SEA-BCMA 200 mg as a monotherapy q2wk IV on Day 1 and 15 of each 28- day cycle. Participants received treatment until disease progression, unacceptable toxicity, withdrawal of consent, death, or study termination, whichever occurs first.

Part A: SEA-BCMA 400mg

Participants received SEA-BCMA 400 mg as a monotherapy q2wk IV on Day 1 and 15 of each 28- day cycle. Participants received treatment until disease progression, unacceptable toxicity, withdrawal of consent, death, or study termination, whichever occurs first.

Part A: SEA-BCMA 800mg

Participants received SEA-BCMA 800 mg as a monotherapy q2wk IV on Day 1 and 15 of each 28- day cycle. Participants received treatment until disease progression, unacceptable toxicity, withdrawal of consent, death, or study termination, whichever occurs first.

Part A: SEA-BCMA 1600mg

Participants received SEA-BCMA 1600 mg as a monotherapy q2wk IV on Day 1 and 15 of each 28- day cycle. Participants received treatment until disease progression, unacceptable toxicity, withdrawal of consent, death, or study termination, whichever occurs first.
