European Medicines Agency (EMA) Grants Orphan Designation for AOC 1001
LA JOLLA, Calif., Aug. 24, 2021 /PRNewswire/ -- Avidity Biosciences, Inc. (Nasdaq: RNA), a biopharmaceutical company committed to delivering a new class of RNA therapeutics called Antibody Oligonucleotide Conjugates (AOCs™), announced that the European Commission (EC) has granted orphan designation for AOC 1001. The U.S. Food and Drug administration also granted orphan drug designation to AOC 1001 earlier this summer.
The U.S. Food and Drug Administration (FDA) cleared Avidity to proceed with the Phase 1/2 MARINATM trial of AOC 1001 in adults with myotonic dystrophy type 1 (DM1) in the United States.
“We are pleased that both the EC and the FDA have granted AOC 1001 Orphan Designation, further validating AOCs as a powerful new class of drugs that can bring benefit to people suffering from untreated and undertreated diseases,” said Sarah Boyce, president and chief executive officer of Avidity. “AOC 1001 is designed to address the root cause of DM1 and has the potential to be a first-in-class treatment for people living with this debilitating rare disease.”
The EC grants orphan designation to drugs and biologics intended for the treatment, diagnosis or prevention of rare, life-threatening or chronically debilitating diseases or conditions that impact fewer than 5 in 10,000 patients in the European Union. Orphan designation allows companies certain benefits, including reduced regulatory fees, clinical protocol assistance, research grants and 10 years of market exclusivity following regulatory approval.
About Myotonic Dystrophy Type 1 and AOC 1001
Myotonic dystrophy type 1 (DM1) is an underrecognized, progressive and often fatal disease caused by a triplet-repeat on the DMPK gene, resulting in a toxic gain of function mRNA. The disease is highly variable with respect to severity, presentation and age of onset, however all forms of DM1, are associated with high levels of disease burden and may cause premature mortality. DM1 primarily affects skeletal and cardiac muscle, however patients can suffer from a constellation of manifestations including myotonia and muscle weakness, respiratory problems, fatigue, hypersomnia, cardiac abnormalities, severe gastrointestinal complications, and cognitive and behavioral impairment. Currently, there are no treatments for patients living with DM1.
AOC 1001, Avidity’s lead program utilizing its AOC platform, is designed to address the root cause of DM1 by reducing levels of a disease-related mRNA. AOC 1001 consists of a proprietary monoclonal antibody that binds to the transferrin receptor 1 (TfR1) conjugated with a siRNA targeting DMPK mRNA. In preclinical studies, AOC 1001 successfully delivered siRNAs to muscle cells, resulting in a durable, dose-dependent reductions of DMPK RNA across a broad range of muscles including skeletal, cardiac, and smooth muscles. In preclinical studies, AOC 1001 had a favorable safety profile that supports advancement into the clinic. The FDA has cleared Avidity to proceed with the Phase 1/2 MARINATM study of AOC 1001 in adults with DM1. FDA and EMA have granted Orphan Designation for AOC 1001.
About Avidity Biosciences
Avidity Biosciences, Inc.’s mission is to profoundly improve people’s lives by delivering a new class of RNA therapeutics - Antibody Oligonucleotide Conjugates (AOCsTM). Avidity’s proprietary AOCs are designed to combine the specificity of monoclonal antibodies with the precision of oligonucleotide therapies to target the root cause of diseases previously untreatable with RNA therapeutics. Avidity’s lead product candidate, AOC 1001, is designed to treat myotonic dystrophy type 1 (DM1). The FDA has cleared Avidity to proceed with the Phase 1/2 MARINATM trial of AOC 1001 in adults with DM1. Its advancing and expanding pipeline also includes programs in facioscapulohumeral muscular dystrophy (FSHD), Duchenne Muscular Dystrophy (DMD), muscle atrophy and Pompe disease. The company is planning for AOC 1044, the lead of three programs for the treatment of DMD, and its AOC FSHD program to enter the clinic in 2022. Avidity is also broadening the reach of AOCs beyond muscle tissues through both internal discovery efforts and key partnerships as the company continues to deliver on the RNA revolution. Avidity is headquartered in La Jolla, CA. For more information about our science, pipeline and people, please visit www.aviditybiosciences.com and engage with us on LinkedIn and Twitter.
