Summary

ATR 1072 is an investigational medicine being studied in adults with PRKAG2 Syndrome. This study will evaluate the safety of ATR 1072 and how the body processes the drug. Researchers will also assess how ATR 1072 affects PRKAG2 activity and measures of heart disease.

Detailed Description

ATR 1072 is an antibody-oligonucleotide conjugate (AOC) designed to reduce expression of PRKAG2 through targeted delivery of siRNA to cardiac tissue. This first-in-human, Phase 1/2, open-label, multicenter study will evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and exploratory efficacy of multiple doses of ATR 1072 in adults with PRKAG2 Syndrome. The study consists of a multiple ascending dose portion (Part A) followed by a dose-expansion cohort at the dose selected in (Part A). After completion of a 48-week treatment period, participants in Parts A and B enter a 42-week extension period followed by a post-treatment follow-up of up to 18 weeks. Approximately 37 participants will be enrolled globally.
