NCT ID NCT06260709

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.

Summary

This study tests the long-term safety of an experimental drug called NNC6019-0001 in people with transthyretin amyloid cardiomyopathy, a rare heart disease that can lead to heart failure. All 80 participants have already completed an earlier study and will receive the drug every 4 weeks for up to 3 years. Researchers will monitor side effects and measure changes in walking ability, heart function, and quality of life.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
NNC6019-0001
What this could lead to
If it works, this could point toward a treatment that reduces heart failure symptoms and improves daily function for people with this rare heart disease.
What could go wrong
This is a small, early-phase extension study with no placebo group, so results may not prove effectiveness. Long-term safety is still unknown.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Completed study intervention in NN6019-4940 and attended the last study visit (week 64; visit 16), and no later than 12 weeks after visit 16. * Expected to be on stable doses of cardiovascular medical therapy 6 weeks prior to the enrolment visit. Exclusion Criteria: * A prior solid organ transplant. * Presence or history of malignant neoplasm (other than basal or squamous cell skin cancer, in-situ carcinomas of the cervix, or in-situ/high grade prostatic intraepithelial neoplasia (PIN) or low-grade prostate cancer) within 5 years before screening. * Current treatment with calcium channel blockers with conduction system effects (e.g., verapamil, diltiazem). The use of dihydropyridine calcium channel blockers is allowed.
