Study to Evaluate Change in Disease Activity and Adverse Events of Subcutaneous Etentamig Compared With Daratumumab Plus Cyclophosphamide Plus Bortezomib Plus Dexamethasone (Dara-CyBorD) in Adults With Amyloid Light Chain (AL) Amyloidosis

2026年8月26日 更新者:AbbVie

A Phase 3 Multicenter, Randomized, Open-Label Study Evaluating the Safety and Efficacy of Etentamig (ABBV-383) Compared to Daratumumab, Cyclophosphamide, Bortezomib, and Dexamethasone (Dara-CyBorD) in Subjects With Newly Diagnosed Amyloid Light Chain (AL) Amyloidosis

Amyloid light chain (AL) amyloidosis is a rare disease caused by abnormal plasma cells producing misfolded light chain proteins that deposit in organs, leading to organ dysfunction and failure. The goal of this study is to evaluate the safety and efficacy of etentamig compared to daratumumab plus cyclophosphamide plus bortezomib plus dexamethasone (Dara-CyBorD) in participants with newly diagnosed AL amyloidosis.

Etentamig is an investigational drug being developed for the treatment of newly diagnosed AL amyloidosis. This is an open-label study. The study consists of 2 parts: a Safety Run-in where participatns will receive etentamig, and a Randomized Portion with 2 treatment arms where participants will receive etentamig, or Dara-CyBorD. Approximately 370 participants will be enrolled in the study at approximately 130 sites worldwide.

Participants will receive injected etentamig, in the Safety Run-in. Participants will receive injected etentamig, or Dara-CyBorD per the local label, in the Randomized Portion of the study. The total study duration is approximately 96 months.

There may be higher treatment burden for participants in this trial compared to their standard of care due to study procedures. Participants will attend regular visits during the study at a hospital or clinic. The effects of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

大体时间
Number of Participants With Adverse Events
大体时间:Up to Approximately 96 Months
An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment. The investigator assesses the relationship of each event to the use of study drug. Safety and tolerability assessed through adverse events, laboratory tests, vital signs, physical examinations, and other safety assessments.
Up to Approximately 96 Months
Randomized Portion: Complete Hematologic Response (HemeCR) Rate
大体时间:Up to Approximately 60 Months
HemeCR rate is defined as the proportion of subjects with the best overall response of hemeCR as determined by International Amyloidosis Consensus Criteria (IACC) and assessed by the independent review committee (IRC)
Up to Approximately 60 Months
Randomized Portion: Major Organ Deterioration Progression-Free Survival (MOD-PFS)
大体时间:Up to Approximately 60 Months
MOD-PFS is defined as the time from the date of randomization to the date of MOD-PFS event or death from any cause, whichever occurs first. MOD-PFS includes: Development of hematologic progressive disease per consensus guidelines or high-risk difference in free light chain (dFLC) progression; Clinical manifestation of cardiac failure (defined as need for cardiac transplant, left ventricular assist device, or intra-aortic balloon pump); Clinical manifestation of renal failure (defined as development of end-stage renal disease needing hemodialysis or renal transplant); Death. MOD-PFS will be assessed by an Independent Review Committee.
Up to Approximately 60 Months
