Avidity Biosciences Highlights FSHD Program at Virtual Investor and Analyst Event

LA JOLLA, Calif., Dec. 9, 2021 /PRNewswire/ -- Avidity Biosciences, Inc. (Nasdaq: RNA), a biopharmaceutical company committed to delivering a new class of RNA therapeutics called Antibody Oligonucleotide Conjugates (AOCs™), today announced it will be hosting a live webcast investor and analyst day event titled "Volume 3: Delivering on AOCs - FSHD" at 11:00am ET.

Volume 3 Highlights:

• AOC 1020 named as clinical development candidate for Facioscapulohumeral Muscular Dystrophy (FSHD) program. AOC 1020 is now entering IND-enabling studies.
• Avidity anticipates three programs in clinical development by the end of 2022. Clinical trial initiations for AOC 1020 and AOC 1044, Avidity's lead program for Duchenne Muscular Dystrophy (DMD) targeting Exon 44, are anticipated by the end of 2022.
• AOC 1001 MARINA study in adults with myotonic dystrophy (DM1) is ongoing and continues to enroll patients. Avidity is on track to conduct a preliminary assessment of safety, tolerability and key biomarkers in approximately half of the study participants in the Phase 1/2 MARINA trial in the fourth quarter of 2022.

"It is well known that the inappropriate expression of DUX4 is the underlying cause of FSHD but before now, the technology didn't exist to target it directly. Our AOC platform, combined with our expertise in skeletal muscle diseases, enabled us to design AOC 1020 to directly target DUX4 and reduce its expression," said W. Michael Flanagan, Ph.D., chief technical officer. "We are grateful to have Dr. Jeffrey Statland join today to give a clinical perspective of FSHD and to share the scientific and research advancements being made to better understand this progressive and debilitating disease with no treatment options."

Today's Video Webcast Information

A live video webcast of today's event will be available on the Avidity website at https://aviditybiosciences.investorroom.com/events-and-presentations commencing 8:00 am PT / 11:00am ET. Following the event, a replay will be archived on Avidity's website.

Avidity's management team will be joined by Jeffrey M. Statland, M.D., one of the principal investigators for the multiple clinical studies in FSHD, including the ongoing Motor Outcomes to Validate Evaluations in FSHD (MOVE FSHD) study and its sub-study, MOVE Plus (MOVE+) being run by the FSHD Clinical Trial Research Network. Dr. Statland is a Professor of Neurology at the University of Kansas Medical Center in Kansas City, Kansas.
