What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing CAEL-101, a special medicine, in patients with severe AL amyloidosis. The goal is to see if it helps clear harmful protein deposits from their organs and improves their survival. The study will compare CAEL-101 with standard treatments.

Do I need to stop my current medications to join the trial?

The trial protocol does not specify whether you need to stop taking your current medications. However, it mentions that participants should not have received prior therapy for AL amyloidosis or multiple myeloma, except for a limited exposure to a specific treatment regimen. It's best to discuss your current medications with the trial team.

Is CAEL-101 safe for humans?

The safety data for CAEL-101 specifically is not available, but similar treatments like CyBorD, which includes some of the same components, have been generally well tolerated in patients with AL amyloidosis, showing few side effects and no new safety concerns in trials. ^{1 2 3 4 5}

How does the drug CAEL-101 differ from other treatments for amyloidosis?

The treatment CAEL-101 is unique because it is being studied in combination with the CyBorD regimen, which includes cyclophosphamide, bortezomib, and dexamethasone, known for inducing rapid responses in AL amyloidosis. This combination aims to enhance outcomes, especially in high-risk groups, by potentially offering a novel mechanism of action or improved efficacy compared to existing treatments. ^{1 2 4 6 7}

What data supports the effectiveness of the drug CAEL-101 for amyloidosis?

The CyBorD regimen, which is part of the treatment being studied, has shown effectiveness in treating AL amyloidosis by producing rapid and complete responses in many patients. It is well tolerated and has been used successfully in patients with multiple organ involvement. ^{1 2 4 8 9}

Are You a Good Fit for This Trial?

This trial is for patients with Mayo Stage IIIa AL Amyloidosis, a condition where abnormal proteins build up in organs. Participants must have heart involvement, measurable hematologic disease, and agree to use effective contraception. Those with other amyloidosis types or prior treatments for AL amyloidosis (except limited CyBorD regimen) are excluded.

Inclusion Criteria

Patients must be at least 18 years of age

My diagnosis of amyloidosis was confirmed with specific tests on tissue samples.

Women of childbearing potential (WOCBP) must have a negative pregnancy test during Screening and must agree to use highly effective contraception from Screening to at least 5 months following the last study drug administration or 12 months following the last dose of her PCD therapy, whichever is longer

Exclusion Criteria

I have POEMS syndrome or multiple myeloma with specific symptoms or test results.

My condition is not AL amyloidosis.

I have been treated for AL amyloidosis or multiple myeloma, but only briefly used a specific treatment regimen.

What Are the Treatments Tested in This Trial?

Interventions

• CAEL-101
• CyBorD regimen
• Placebo

Trial Overview The study tests CAEL-101's effectiveness and safety against placebo when added to the standard CyBorD treatment regimen. CAEL-101 is an antibody designed to clear out harmful protein deposits from tissues in patients with advanced cardiac AL Amyloidosis.

How Is the Trial Designed?

Group I: CAEL-101 combined with SoC plasma cell dyscrasia Experimental Treatment 2 Interventions

The study is divided into 2 parts, the Primary Study and the Open-Label Extension Study. CAEL-101 is administered as an intravenous (IV) infusion over approximately 2 hours. It is planned that all patients will continue their double-blind treatment until the last patient is randomized in the study plus 18 months.

Group II: Placebo combined with SoC plasma cell dyscrasia Placebo Group 2 Interventions

Patients randomized to receive placebo will receive 0.9% normal saline in an equivalent volume to a CAEL-101 infusion (approximately 250 cc). It is planned that all patients will continue their double-blind treatment until the last patient is randomized in the study plus 18 months.

Published Research Related to This Trial

The combination therapy of daratumumab, cyclophosphamide, bortezomib, and dexamethasone (daratumumab-CyBorD) has become the new standard-of-care for systemic light chain (AL) amyloidosis, showing high rates of hematologic and organ response.

Recent advancements in patient selection and induction regimens have significantly reduced the mortality associated with autologous stem cell transplant (ASCT), while new treatments like venetoclax are proving effective for patients with specific genetic abnormalities.

Advances in the treatment of light chain amyloidosis. Palladini, G., Milani, P.[2023]

In a study comparing two treatment regimens for AL amyloidosis, cyclophosphamide, bortezomib, and dexamethasone (CVD) showed a higher complete response rate (40.5%) compared to cyclophosphamide, thalidomide, and dexamethasone (CTD) (24.6%), indicating that CVD may be more effective in achieving deeper responses.

CVD also demonstrated superior progression-free survival (28.0 months) compared to CTD (14.0 months), suggesting that CVD may provide longer-lasting benefits for patients, although both regimens still face challenges with early mortality in AL amyloidosis.

In a safety run-in of the ANDROMEDA study involving 28 patients with newly diagnosed AL amyloidosis, the combination of daratumumab and CyBorD showed a high overall hematologic response rate of 96%, with 54% achieving a complete response.

The treatment was well tolerated, with minimal adverse events and no new safety concerns compared to the intravenous formulation, indicating its potential as a safe and effective option for patients with AL amyloidosis.
