Study to Evaluate Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of NTLA-2001 in Patients With Hereditary Transthyretin Amyloidosis With Polyneuropathy (ATTRv-PN) and Patients With Transthyretin Amyloidosis-Related Cardiomyopathy (ATTR-CM)

Transthyretin-Related (ATTR) Familial Amyloid Polyneuropathy Clinical Trial

Official title: Phase 1 Two-Part (Open-label, Single Ascending Dose (Part 1) and Open-label, Single Dose Expansion (Part 2)) Study to Evaluate Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of NTLA-2001 in Patients With Hereditary Transthyretin Amyloidosis With Polyneuropathy (ATTRv-PN) and Patients With Transthyretin Amyloidosis-Related Cardiomyopathy (ATTR-CM)

Status Active, not recruiting

Clinical Trial Summary

This study will be conducted to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of NTLA-2001 in participants with hereditary transthyretin amyloidosis with polyneuropathy (ATTRv-PN) and participants with hereditary transthyretin amyloidosis with cardiomyopathy (ATTRv-CM) or wild type cardiomyopathy (ATTRwt-CM)

Clinical Trial Description

For ATTRv-PN participants, Part 1 consists of an open-label, single-ascending dose study, which identifies the dose for evaluation in the cohort expansion of Part 2. Part 2 will follow as an open-label, dose expansion study to further characterize the activity of NTLA-2001, provide an initial assessment of the effect of NTLA-2001 on clinical measures of neuropathy and neurological function, and obtain additional safety data.

For ATTR-CM participants, Part 1 consists of an open-label, single-ascending dose study, which identifies the dose for evaluation in the cohort expansion of Part 2. Part 2 will follow as an open-label, dose expansion study to further characterize the activity of NTLA-2001, provide an initial assessment of the effect of NTLA-2001 on cardiac measures, and obtain additional safety data.

All participants who are dosed with NTLA-2001 will be offered to participate in a long-term safety monitoring follow-up study via a separate protocol. ;
