Avidity Biosciences Reports Second Quarter 2024 Financial Results and Recent Highlights

Avidity reports positive del-zota (AOC 1044) data; demonstrated 25% increase in dystrophin production and reduction of creatine kinase levels to near normal in people living with DMD44 in Phase 1/2 EXPLORE44™ trial

Initiated global Phase 3 HARBOR™ trial and began administration of del-desiran in people living with DM1; del-desiran received FDA Breakthrough Therapy designation

Avidity plans to accelerate initiation of del-brax (AOC 1020) registrational cohorts after reporting unprecedented and consistent reductions in DUX4 regulated genes, trends of functional improvement and favorable safety and tolerability in people living with FSHD in Phase 1/2 FORTITUDE™ trial

Announcement of our lead precision cardiology program target planned for Q4 2024

Cash on hand of approximately $1.3 billion

SAN DIEGO, Aug 9, 2024 /PRNewswire/-- Avidity Biosciences, Inc. (Nasdaq: RNA), a biopharmaceutical company committed to delivering a new class of RNA therapeutics called Antibody Oligonucleotide Conjugates (AOCs™), today reported financial results for the second quarter ended June 30, 2024, and highlighted recent corporate progress.

“The last few months have been incredible for Avidity, but more importantly, for people living with DM1, FSHD and DMD. We received breakthrough designation for del-desiran, initiated the global Phase 3 HARBOR™ trial, reported unprecedented data from the del-brax FORTITUDE™ trial and earlier today, shared data from del-zota’s Phase 1/2 EXPLORE44™ trial demonstrating significant increases in dystrophin production and exon 44 skipping for people living with DMD44,” said Sarah Boyce, president and chief executive officer at Avidity. “All of this progress is due to our AOC platform which has proven we can target a range of genetic diseases. We plan to expand beyond rare neuromuscular diseases as we share the first target from our precision cardiology pipeline in Q4 2024. These achievements, accomplished in conjunction with our patient communities, accelerate our vision of profoundly improving people’s lives by revolutionizing RNA delivery.”

“We successfully closed an upsized public offering in June, our second successful equity raise this year. Our cash position of ~$1.3 billion at the end of the second quarter, allows us to progress our current clinical trials and expand our DMD franchise to include multiple potential treatments for people living with Duchenne Muscular Dystrophy beyond DMD44,” said Mike MacLean, chief financial officer and chief business officer at Avidity.

Recent Highlights
Del-zota (AOC 1044)
•In August, Avidity reported positive initial del-zota 5mg/kg patient data from the Phase 1/2 EXPLORE44™ trial in people living with DMD44 demonstrating unsurpassed delivery in skeletal muscle, unprecedented increase in dystrophin production, robust exon 44 skipping, and a profound reduction in creatine kinase
•In the Phase 1/2 EXPLORE44 trial, del-zota data from 10 participants at the four-month time period after three doses of 5mg/kg del-zota (PMO dose), or placebo every six weeks, demonstrated:
◦Unsurpassed delivery of PMO of 200 nM in skeletal muscle
◦Statistically significant 37% increase in exon 44 skipping and up to 66% exon 44 skipping compared to baseline
◦Statistically significant increase of 25% of normal in dystrophin production and restored total dystrophin up to 54% of normal
◦Profound reduction in creatine kinase as levels were reduced to near normal with greater than 80% reduction compared to baseline
•Safety and tolerability for 25 participants was assessed across two dose levels (5 mg/kg and 10 mg/kg) from the Phase 1/2 EXPLORE44 trial. Del-zota demonstrated favorable safety and tolerability with most treatment emergent adverse events (AEs) mild or moderate in participants with DMD44
•Enrollment is now complete for the Phase 1/2 EXPLORE44 trial. Avidity plans to enroll additional patients in the EXPLORE44 Open-label Extension study (OLE)
•Avidity introduced delpacibart zotadirsen as the approved international nonproprietary name of AOC 1044, abbreviated as del-zota

Del-desiran (AOC 1001)
•In June, Avidity initiated and began administration of del-desiran in the global Phase 3 HARBORTM trial in people living with myotonic dystrophy type 1 (DM1)
•The FDA granted del-desiran Breakthrough Therapy designation in May 2024 for DM1

Del-brax (AOC 1020)
•Avidity reported positive initial del-brax data from the Phase 1/2 FORTITUDE™ trial demonstrating unprecedented and consistent reductions of greater than 50% in DUX4 regulated genes, trends of functional improvement, and favorable safety and tolerability in people living with facioscapulohumeral muscular dystrophy (FSHD)
•In the Phase 1/2 FORTITUDE trial, del-brax 2 mg/kg data from 12 participants at the four-month time period demonstrated:
◦Greater than 50% mean reductions in DUX4 regulated genes across multiple panels for DUX4 regulated gene expression in muscle
◦All participants treated with del-brax showed reductions greater than 20% in DUX4 regulated genes
◦Mean reductions of 25% or greater in a novel circulating biomarker and creatine kinase
◦Trends of functional improvements including increased strength in upper and lower limb muscles, and muscle function as measured by reachable workspace (RWS) compared to placebo and the ReSolve natural history study

gfnzizaxnpmk000001.jpg
◦Trends of improvement in patient and clinician reported outcomes
•A four-month look at the safety and tolerability for all 39 participants across two dose levels (2 mg/kg and 4 mg/kg) from the Phase 1/2 FORTITUDE trial demonstrated favorable safety and tolerability with all adverse events (AEs) mild or moderate, no serious adverse events and no discontinuations
•Completed enrollment for the Phase 1/2 FORTITUDE trial. Avidity plans to accelerate the initiation of registrational cohorts with the biomarker cohort planned in 2H 2024 and functional cohort planned in 1H 2025.
•Avidity introduced delpacibart braxlosiran as the approved international nonproprietary name of AOC 1020, abbreviated as del-brax

Pipeline Advancements
•Avidity plans to announce its lead precision cardiology program target in Q4 2024

The increases were primarily driven

gfnzizaxnpmk000001.jpg
by the advancement of del-desiran, del-brax and del-zota, as well as internal and external costs related to the expansion of the company’s overall research capabilities.

•General and Administrative (G&A) Expenses: G&A expenses primarily consist of employee-related expenses, professional fees, insurance costs and patent filing and maintenance fees.
