Brief Summary

Phase 3 efficacy and safety of acoramidis in subjects with symptomatic Transthyretin Amyloid Polyneuropathy (ATTR-PN)

Detailed Description

Transthyretin amyloid polyneuropathy (ATTR-PN), also called "Familial Transthyretin-Mediated Amyloid Polyneuropathy (FAP)" is a hereditary condition caused by mutations in the TTR gene. It is estimate...

Eligibility Criteria

Inclusion

  • Male or female ≥18 to ≤90 years of age;
  • Have Stage I or II symptoms (polyneuropathy disability \[PND\] ≤IIIb) of ATTR-PN and an established diagnosis of ATTR-PN as defined by physical examination findings and/or neurophysiological test findings consistent with the diagnosis of ATTR-PN;
  • Have an NIS of 5 to 130 (inclusive) during Screening;
  • Have a nerve conduction studies (NCS) score (sum of the sural sensory nerve action potential \[SNAP\], tibial compound muscle action potential (CMAP), ulnar SNAP, ulnar CMAP, and peroneal CMAP) of ≥2 points during Screening. NCS is a component of mNIS+7;
  • Have a mutation consistent with ATTR-PN either documented in medical history or confirmed by genotyping obtained at Screening prior to enrollment. No genetic testing is needed for subjects who are recipients of domino liver transplants;
  • Have an anticipated survival of \>2 years in the opinion of the investigator;
  • Have Karnofsky performance status ≥60 %.

Exclusion

  • Had a prior liver transplantation or is planning to undergo liver transplantation with a wild-type organ graft as treatment for symptomatic ATTR-PN during the study period. Note: Recipients of a "domino" liver transplant from an ATTR-PN donor who have developed ATTR-PN mediated by their graft are allowed under this protocol, as long as re-transplantation to treat ATTR-PN is not planned during the study period and meets all other eligibility criteria;
  • Has sensorimotor or autonomic neuropathy not related to ATTR-PN; for example, due to autoimmune disease or monoclonal gammopathy, malignancy, or alcohol abuse;
  • Has Vitamin B-12 levels below the lower limit of normal (LLN) at Screening;
  • Has clinical evidence of untreated hyperthyroidism or hypothyroidism;
  • Has leptomeningeal TTR amyloidosis;
  • Has Type 1 diabetes;
  • Has had Type 2 diabetes for ≥5 years;
  • Has a documented case of hepatitis B or C at Screening;
  • Known history of human immunodeficiency virus (HIV) infection;
  • Has NYHA heart failure classification \>Class II;
  • Had acute coronary syndrome, uncontrolled cardiac arrhythmia, or a stroke within 90 days prior to Screening;
  • Has estimated glomerular filtration rate (eGFR) by Modification of Diet for Renal Disease (MDRD) formula \<30 mL/min/1.73 m2 at Screening;
  • Has abnormal liver function tests at Screening, defined as alanine aminotransferase (ALT) or aspartate aminotransferase (AST) \>3 × upper limit of normal (ULN) or total bilirubin \>3 × ULN;
  • Had a malignancy within 2 years, except for basal or squamous cell carcinoma of the skin or carcinoma in situ of the cervix that has been successfully treated;
  • Has known hypersensitivity to acoramidis, its metabolites, or formulation excipients.
  • Is currently undergoing treatment for ATTR-PN with tafamidis, or patisiran, inotersen, or other knockdown agents, marketed drug products lacking a labeled indication for ATTR-PN (e.g., diflunisal, doxycycline), natural products or derivatives used as unproven therapies for ATTR-PN (e.g., green tea extract ,tauroursodeoxycholic acid \[TUDCA\]/ursodiol), within 14 days, or 14 days for tafamidis or 90days for patisiran and 180 days for inotersen prior to dosing.
