Frequently asked questions about Coramitug

What is Coramitug used for?

Coramitug is being developed for transthyretin amyloid cardiomyopathy (ATTR CM), a form of heart failure caused by transthyretin amyloid deposits in heart tissue. It is an investigational small molecule studied in adults with this condition. Clinical development includes a Phase 3 trial and earlier-phase studies in patients with ATTR amyloidosis affecting the heart.

Who is developing Coramitug?

Coramitug is developed by Novo Nordisk A/S, which trades under the ticker NVO. Novo Nordisk sponsors the clinical program, including the Phase 3 CLEOPATTRA study and earlier-phase trials in transthyretin amyloid cardiomyopathy. The drug is also referred to in company materials by the code NNC6019-0001.

What phase is Coramitug in?

Coramitug is in Phase 3 development. The Phase 3 CLEOPATTRA trial is currently recruiting, and earlier Phase 1 and Phase 2 studies have also been conducted. Coramitug is investigational and has not been approved for commercial use; it remains in clinical development for transthyretin amyloid cardiomyopathy.

What clinical trials is Coramitug in?

Coramitug has been studied in four clinical trials. The Phase 3 CLEOPATTRA study (NCT07207811) is recruiting about 1,280 participants across many countries. Other trials include a Phase 1 PET/CT imaging study (NCT07448623), an active Phase 2 long-term treatment study (NCT06260709), and a completed Phase 2 study (NCT05442047).

Is Coramitug the same as NNC6019-0001?

Yes. Coramitug and NNC6019-0001 refer to the same investigational medicine from Novo Nordisk. NNC6019-0001 is the company code used in earlier trial titles, while Coramitug is the name used in newer studies such as the Phase 3 CLEOPATTRA trial in transthyretin amyloid cardiomyopathy.

How many people have been enrolled in Coramitug trials?

Across the four reported Coramitug trials, total planned enrollment is about 1,487 participants. The largest is the Phase 3 CLEOPATTRA trial with roughly 1,280 participants. The studies are randomized, double-blind, and placebo-controlled, and participants are selected based on biomarkers related to transthyretin amyloid cardiomyopathy.
