Overview
Several investigational products targeting ATTR amyloid are being studied in clinical trials. These include small interfering RNA (siRNA) molecules which reduce the production of the amyloid precursor misfolded protein and ATTR stabilization molecules.
Future or Investigational Therapies
Potential future treatment options targeting cardiac TTR amyloidosis include:
- AG10: AG10 is a selective, oral TTR stabilizer which mimic a protective TTR mutation known as T119M. In a phase 2 clinical trial, AG10 was found to be safe and effective. This trial randomized 49 patients with mutant or wild-type TTR amyloid cardiomyopathy with NYHA class II to III symptoms to AG10 400 mg, 800 mg, or placebo twice daily for 28 days, and found the medication to be well tolerated and achieve near-complete stabilization of TTR.[1] A phase 3 trial (ATTRIBUTE-CM) is ongoing (NCT03458130).
- Patisiran: this is a siRNA molecule which has shown promise in patients with polyneuropathy from hereditary TTR amyloidosis. A cardiac subgroup study showed favorable biomarker results as well.[2]
