Avidity Biosciences Reports First Quarter 2022 Financial Results and Recent Highlights

SAN DIEGO, May 10, 2022 /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 financial results for the first quarter ended March 31, 2022 and highlighted recent corporate progress.       

"This year will prove to be significant for Avidity as we look forward to sharing a mid-point update from the AOC 1001 MARINA^TM trial in adults with myotonic dystrophy type 1 in Q4 and advancing two additional programs, AOC 1020 and AOC 1044, into the clinic," said Sarah Boyce, president and chief executive officer. "We continue to build our infrastructure to support our goal of having three programs addressing three distinct rare diseases in clinical development by the end of this year. With our AOC platform technology, we aim to revolutionize the delivery of RNA therapeutics as we fulfill our mission of profoundly improving people's lives affected by serious diseases."

"We are well funded into 2024 with a cash balance of $397 million at the end of Q1 2022. This will allow us to complete the AOC 1001 MARINA trial, advance our programs for facioscapulohumeral muscular dystrophy and Duchenne muscular dystrophy  Exon 44 into the clinic and continue to progress our AOC platform in other indications," said Mike MacLean, chief financial and chief business officer.

Recent Highlights

• Presented two oral and three poster presentations at the American Academy of Neurology (AAN) 2022 Annual Meeting. Key highlights included:
  • A review of the MARINA trial including a high level update on safety and enrollment. The company reiterated that the trial is on track for a preliminary assessment in approximately half of patients in Q4 2022
  • Data from an in vivo proof-of-concept study using the MDX mouse model supporting Avidity's Duchenne muscular dystrophy programs and demonstrating that an AOC effectively delivered RNA therapeutics to muscle and heart tissues
• Appointed Steve Hughes, M.D., as chief medical officer and, in April, expanded the role of Michael MacLean to chief financial and chief business officer.

First Quarter 2022 Financial Results

• Cash, Cash Equivalents and Marketable Securities: Cash, cash equivalents and marketable securities totaled $397.1 million as of March 31, 2022, compared to $405.5 million as of December 31, 2021.

The increase was primarily driven by the advancement of AOC 1001, AOC 1020 and AOC 1044, as well as costs related to the expansion of the company's overall research capabilities.

These expenses were $8.6 million for the first quarter of 2022 compared with $5.9 million for the first quarter of 2021. The increase was primarily due to higher personnel costs and professional fees to support the company's expanded operations.
