Date of first enrollment | 27/03/2024 |
Target sample size | 76 |
Countries of recruitment | |
Study type | Interventional |
Intervention(s) | ABBV-383: Intravenous Infusion (Other Names: TNB-383B) |
Outcome(s)
Primary Outcome | Number of Participants with Dose-Limiting Toxicities (DLT) [Time Frame: Up to 28 Days] |
---|---|
Secondary Outcome | 1. Percentage of Participants who Achieve Hematologic Complete Response (CR) [Time Frame: Up to 3 Years] - Hematologic CR is defined as the percentage of participants who achieve normalization of free light chain levels, negative serum immunofixation, negative urine immunofixation as determined per the International Amyloidosis Consensus Criteria. 2. Overall Hematologic Response (OHR) [Time Frame: Up to 3 Years] - OHR is defined as partial response (PR) + very good partial response (VGPR) + complete remission (CR), proportion of participants who achieved a PR or better, per the International Amyloidosis Consensus Criteria. 3. Time to Hematologic CR [Time Frame: Up to 3 Years] - Time to hematologic CR is defined as the time from first dose of study drug until CR, per the International Amyloidosis Consensus Criteria. 4. Duration of Hematologic CR [Time Frame: Up to 3 Years] - Duration of hematologic CR is defined as the time from CR until disease progression, per the International Amyloidosis Consensus Criteria. 5. Organ Response Rate (OrRR) [Time Frame: Up to 3 Years] - Organ response rate is defined as the time from first dose of study drug until to response in the heart kidney and liver, per the International Amyloidosis Consensus Criteria. 6. Time to Organ Response [Time Frame: Up to 3 Years] - Time to organ response is defined as the time from first dose of study drug until organ response, per the International Amyloidosis Consensus Criteria. |
