Summary

The goal of this study is to evaluate the efficacy and safety of Sonrotoclax combined Regimen in patients with t(11;14) AL amyloidosis. Participants will receive the Sonrotoclax Plus Dexamethasone regimen with or without Daratumumab for 12 cycles. The Hematologic Response, Organ Response, Survival, and Safety will be evaluated.

Detailed description

Treatment options for AL amyloidosis are limited. Before the approval of daratumumab, newly diagnosed light-chain amyloidosis was often managed with anti-myeloma regimens such as bortezomib. For patients with relapsed/refractory (R/R) disease, there is currently a lack of standard treatment options both domestically and internationally. Guidelines recommend enrollment in clinical trials or the use of regimens containing previously unexposed agents, such as bortezomib or daratumumab. Based on preliminary data of BCL-2 inhibitors in t(11;14) amyloidosis, this study aims to explore the efficacy and safety of sonrotoclax and dexamethasone with or without Daratumumab. Newly diagnosed patients with t（11;14）will receive the combination of sonrotoclax, daratumumab, and dexamethasone. t(11;14) Patients with relapsed/refractory AL amyloidosis (RRAL) will be treated with sonrotoclax plus dexamethasone. For transplant-eligible patients, stem cell collection is permitted during the induction phase of therapy. The timing of ASCT may be assessed after the primary endpoint evaluation (completion of 4 treatment cycles) and determined by the investigator.

Conditions

• AL Amyloidosis (AL)
• t(11;14) Positive

Interventions

Type	Name	Description
DRUG	sonrotoclax	t(11;14) AL amyloidosis Newly diagnosed or previously untreated with anti-CD38 mAb therapy Induction therapy (C1-4) Sonrotoclax once daily ( dose depends on the 3+3 study design during safety run-in period in C1) Consolidation therapy (C5-12) Sonrotoclax once daily (same as the target dose in induction therapy) t(11;14) AL patients insensitive to or relapsed after anti-CD38 mAb therapy Induction therapy (C1-4) Sonrotoclax once daily (dose depends on the 3+3 study design during safety run-in period in C1) Consolidation therapy (C5-12) Sonrotoclax once daily (same as the target dose in induction therapy)
DRUG	Daratumumab	t(11;14) AL patients insensitive to or relapsed after anti-CD38 mAb therapy Daratumumab (16 mg/kg intravenously or 1800 mg subcutaneously, once weekly C1-2; every two weeks C3-6; every month C7-12)
DRUG	Dexamethasone	Dexamethasone (40 mg, once weekly) for 12 cycles. The dose was halved for patients 75 years of age or older, and in patients who were intolerant of dexamethasone, as judged by the investigators.
