LA JOLLA, Calif., April 16, 2021 /PRNewswire/ -- Avidity Biosciences Inc. (Nasdaq: RNA), a biopharmaceutical company pioneering a new class of oligonucleotide-based therapies called Antibody Oligonucleotide Conjugates (AOCs™), today announced that preclinical data for their lead candidate, AOC 1001 in development for myotonic dystrophy type 1 (DM1), will be presented at the American Academy of Neurology (AAN) 2021 Virtual Annual Meeting being held April 17-22, 2021.
The abstract on AOC 1001 was chosen by the AAN Science Committee as one of 11 abstracts to be highlighted in the Emerging Science Session.
"We are honored to be part of the Emerging Science session at such a prestigious meeting and are grateful to the AAN Science Committee for highlighting AOC 1001. AOC 1001 is targeting DM1, a complex disease with variability from patient to patient and no approved treatments," said Art Levin, Ph.D., Chief Scientific Officer. "Our data presented at AAN show that AOC 1001 is highly potent with demonstrated activity in the nucleus and cytoplasm and that single doses of AOC 1001 produced 75% reductions in DMPK mRNA expression that were maintained for months post-dosing. These results further solidify AOC 1001 as a promising program with the potential to be the first therapy for people living with DM1."
Details of the oral presentation are below:
Title: "Optimization of AOC-1001, an antibody-oligonucleotide conjugate targeting the underlying cause of myotonic dystrophy type 1"
Date: Sunday, April 18, 2021 at 3:45 p.m. ET
Session: Emerging Science
Presenter: Barbora Malecova, Ph.D., Associate Director, Biology at Avidity
Avidity scientists have demonstrated activity and potency of siRNAs against the dystrophy protein kinase (DMPK) gene in muscle cells derived from patients with DM1. These data showed significant reductions in DMPK mRNA levels in the nucleus and in the cytoplasm. Treatment with Avidity's therapeutic agent were able to correct the incorrect splicing in these DM1 cells, moving the splicing signature closer to that of healthy cells and indicating the potential to target the underlying cause of DM1. In addition, Avidity scientists have shown the robust, durable activity of AOC 1001 in vivo in a broad range of muscles of non-human primates including cardiac muscle. These data demonstrated a 75% reduction in DMPK mRNA levels in muscles following a single dose of AOC 1001.
Avidity's abstract is available on the AAN meeting website. Following regulatory clearance, the company plans to begin a Phase 1/2 study for AOC 1001 in the second half of 2021.
Avidity Biosciences, Inc. is driven to change lives with a new class of therapies called Antibody Oligonucleotide Conjugates (AOCs) that are designed to overcome current limitations of oligonucleotide therapies in order to treat a wide range of serious diseases. Avidity's proprietary AOC platform combines the tissue selectivity of monoclonal antibodies and the precision of oligonucleotide therapies to access previously undruggable tissue and cell types and more effectively target underlying genetic drivers of diseases. Avidity's lead product candidate, AOC 1001, is designed to treat myotonic dystrophy type 1, and its other muscle programs are focused on the treatment of Duchenne muscular dystrophy, facioscapulohumeral muscular dystrophy, Pompe disease and muscle atrophy. In addition to its muscle franchise, Avidity has research efforts focused on immune, cardiac and other cell types.
