What was measured

A positive baseline ATA result was considered positive post-baseline if the post-baseline ATA titer result was at least four times higher than the baseline result.

Analysis population: All treated participants analysis set included all treated participants who received any amount of SEA-BCMA. Here "Number of Participants Analyzed" signifies participants evaluable for this outcome measure.

Groups in this outcome

Part A: SEA-BCMA 100mg

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.
