This phase 1, randomized, placebo-controlled, double-blind trial in subjects with Amyloid Transthyretin Cardiomyopathy (ATTR-CM) consists of single-ascending dose (SAD) and multiple-ascending dose (MAD) phases, followed by an open-label extension (OLE) phase.~In the SAD phase subjects are randomized in a 4:2 ratio to receive a single infusion of NI006 or placebo.~Subjects completing the SAD phase will be enrolled in the MAD phase upon evaluation of all available safety data and receive a maximum of 3 additional infusions of NI006 or placebo every 28 days.~Subjects completing the MAD phase will have the possibility to continue in an OLE phase with treatment up-titrations and switch from placebo to NI006 and receive up to 8 infusions of NI006 every 28 days.~Subjects of cohort 1 to 5 who received at least one dose of NI006 during the OLE phase will have the possibility for a second OLE phase (OLE2) after completing the OLE phase and receive up to 10 additional infusions of NI006 every 28 days.~In total, about 42 subjects are planned to be enrolled in 7 cohorts of 6 subjects each, at 6 ascending dose levels.
A phase 1, randomized, placebo-controlled, double-blind, dose escalation trial combining single-ascending dose and multiple-ascending dose phases of NI006 or placebo, followed by an open-label extension phase in subjects with Amyloid Transthyretin Cardiomyopathy (ATTR-CM).
