Experimental drug shows promise for stiff heart disease

NCT ID NCT05442047

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tested an experimental drug called NNC6019-0001 in 105 people with transthyretin amyloid cardiomyopathy, a condition where abnormal proteins build up in the heart, causing heart failure. Participants received either the drug or a placebo by infusion every 4 weeks for about 64 weeks. The goal was to see if the drug could improve walking distance and reduce markers of heart strain.

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 (an experimental drug given by infusion)

What this could lead to

If it works, this could point toward a new treatment to manage heart failure symptoms in people with ATTR amyloid cardiomyopathy.

What could go wrong

This is an early Phase 2 trial with only 105 participants, so results may not apply to everyone. The drug is still experimental and not yet approved.
