Summary

This trial tests whether fewer maintenance cycles of a drug can work as well as more cycles to treat AL amyloidosis.

Who is the study for?

This trial is for adults with newly diagnosed AL amyloidosis who've completed specific induction therapy and achieved a certain response level. They must have good enough health to perform daily activities, be able to complete questionnaires, and agree to follow-up visits. Pregnant or nursing individuals, those with hepatitis B/C or HIV on treatment, and patients with multiple myeloma are excluded.

What is being tested?

The EMILIA Trial is testing whether daratumumab maintenance therapy can extend the time without disease symptoms after initial treatment in AL amyloidosis patients. It compares the effects of continuing daratumumab for 3-6 cycles versus 18 cycles following an induction phase.

What are the potential side effects?

Daratumumab may cause side effects like infusion reactions (symptoms similar to allergic reactions during drug administration), fatigue, nausea, low blood cell counts increasing infection risk, and potential heart or lung complications.

Trial Design

2Treatment groups

Experimental Treatment

Active Control

Group I: Arm I (6 cycles of daratumumab)Experimental Treatment6 Interventions

Patients receive daratumumab subcutaneously (SC) on day 1 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity for up to 6 cycles on study. Patients also undergo x-ray imaging at screening and bone marrow biopsy and blood sample collection throughout the study. Patients with cardiac involvement also undergo echocardiography throughout the trial.

Group II: Arm II (18 cycles of daratumumab)Active Control6 Interventions

Patients receive daratumumab SC on day 1 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity for up to 18 cycles on study. Patients also undergo x-ray imaging at screening and bone marrow biopsy and blood sample collection throughout the study. Patients with cardiac involvement also undergo echocardiography throughout the trial.
