Avidity Biosciences, Inc. Announces Final Results from the Completed Phase 1/2 Marine Trial of Delpacibart Etedesiran (Del-Desiran) for Treatment of Myotonic Dystrophy Type 1 Avidity Biosciences, Inc. announced that the final results from the completed Phase 1/2 MARINA® trial of delpacibart etedesiran (del-desiran) in people living with myotonic dystrophy type 1 (DM1) will be published in the February 19 issue of The New England Journal of Medicine (NEJM). The manuscript is titled ‘An Antibody Oligonucleotide Conjugate for Myotonic Dystrophy Type 1.’DM1 is an underrecognized, progressive and often fatal neuromuscular disease with no disease modifying therapies. Del-desiran is an investigational treatment designed to address the underlying genetic root cause of DM1 by reducing total levels of the toxic, DMPK (myotonic dystrophy protein kinase) mRNA. The accumulation of these toxic mRNA sequester key RNA-regulatory proteins that subsequently lead to missplicing of several downstream genes, resulting in the diverse clinical manifestations of disease. The Phase 1/2 MARINA trial was a randomized, double-blind, placebo-controlled study designed to evaluate the safety and tolerability of single and multiple ascending doses of del-desiran administered intravenously in adults with DM1 for six months. Data were assessed from 38 participants who were randomized 3:1 to receive one dose of 1 mg/kg del-desiran, three doses of either 2 mg/kg del-desiran or 4 mg/kg del-desiran (reflected as siRNA dose), or placebo. The primary endpoint of the study was to evaluate the safety and tolerability of del-desiran. Exploratory endpoints were to evaluate the clinical activity of del-desiran across multiple efficacy measures. Results from the Phase 1/2 MARINA study of del-desiran published in NEJM demonstrated: Effective delivery of del-desiran (siRNA) to muscle, with a mean ~ 40% reduction in DMPK mRNA across all treated participants. Splicing improvements in a key set of muscle-specific genes following treatment with del-desiran 2 mg/kg and 4 mg/kg. Improvements in exploratory functional measures including: Hand function/myotonia (video hand opening time, or vHOT); Muscle strength (Quantitative Muscle Testing, or QMT total score); Mobility (10-Meter Walk/Run Test, or 10mWRT, and Timed Up and Go test, or TUG); DM1-Activ, a patient-reported outcome that measures activities of daily living (e.g., taking a shower, visiting family or friends, and walking up stairs). Acceptable safety and tolerability with most treatment emergent adverse events (TEAEs) mild or moderate in participants with DM1 and did not result in discontinuation. Two severe, serious AEs occurred in two participants in the 2 mg/kg and 4 mg/kg dose cohorts, with one participant discontinuing the study in the 4 mg/kg cohort. One of these SAEs was deemed drug-related. Del-desiran (4 mg/kg) is currently being assessed in the global Phase 3 HARBOR™ study in people living with DM1 who are age 16 and older and in the ongoing HARBOR open-label extension (HARBOR-OLE™) trial with all the participants who completed the Phase 1/2 MARINA trial. The global Phase 3 HARBOR study completed enrollment in July 2025 and a 54-week topline data readout is expected in the second half of 2026. Announcement • Nov 19

New Risk • Apr 05
New minor risk - Insider selling There has been significant insider selling in the company's shares over the past 3 months. Total value of shares sold: US$638k This is considered a minor risk. There are several reasons why an insider may be selling, including to cover a tax obligation or pay for some other expense. However, we generally consider it a negative if insiders have been selling, especially if they do so below the current price. It implies that they considered a lower price to be reasonable. This is a weak signal, but if there is a pattern of unexplained selling, it can be a sign the insider believes the company's stock is overpriced. Note: We only include open market transactions and private dispositions of directly owned stock by individuals, not by corporations or trusts. Currently, the following risks have been identified for the company: Minor Risks Currently unprofitable and not forecast to become profitable over next 3 years (US$301m net loss in 3 years).

Avidity Biosciences Receives FDA Rare Pediatric Disease Designation for AOC 1044 for Treatment of Duchenne Muscular Dystrophy in People with Mutations Amenable to Exon 44 Skipping Avidity Biosciences, Inc. announced that the U.S. Food and Drug Administration (FDA) has granted Rare Pediatric Disease designation to AOC 1044, the company's investigational therapy for the treatment of Duchenne muscular dystrophy (DMD) in people living with mutations amenable to exon 44 skipping (DMD44). AOC 1044 is being assessed in the Phase 1/2 EXPLORE44™ trial for people living with DMD44 and is the first of multiple AOCs the company is developing for DMD. In addition to receiving Rare Pediatric Disease Designation, AOC 1044 has been granted Orphan Designation by the FDA and the European Medicines Agency (EMA), and Fast Track Designation by the FDA. DMD is a rare genetic condition that is characterized by progressive muscle damage and weakness due to the loss of dystrophin protein that typically starts at a very young age. Currently, there are no therapies approved targeting exon 44. In December 2023, Avidity reported positive AOC 1044 data in healthy volunteers from the EXPLORE44 trial. AOC 1044 is designed to deliver phosphorodiamidate morpholino oligomers (PMO) to skeletal muscle and heart tissue to specifically skip exon 44 of the dystrophin gene to enable dystrophin production. AOC 1044 delivered unprecedented concentrations of PMO in skeletal muscle with up to 50-times greater concentrations of PMO in skeletal muscle following a single dose compared to peptide conjugated PMOs in healthy volunteers. AOC 1044 was well tolerated, demonstrated statistically significant exon 44 skipping compared to placebo of up to 1.5% in healthy volunteers after a single dose of 10 mg/kg AOC 1044 and increased exon skipping in all participants. Avidity plans to provide a first look at AOC 1044 data in people living with DMD44 in 2H 2024. The FDA defines a "rare pediatric disease" as a serious or life-threatening disease in which the serious or life-threatening manifestations primarily affect individuals aged from birth to 18 years. Under the FDA's Rare Pediatric Disease Priority Review Voucher program, a sponsor who receives an approval for a drug or biologic for a rare pediatric disease may qualify for a voucher that can be redeemed to receive a priority review of a subsequent marketing application for a different product.

About Duchenne muscular dystrophy (DMD) Duchenne muscular dystrophy (DMD) causes a lack of functional dystrophin that leads to stress and tears of muscle cell membranes, resulting in muscle cell death and the progressive loss of muscle function. The dystrophin protein maintains the integrity of muscle fibers and acts as a shock absorber through its role as the foundation of a group of proteins that connects the inner and outer elements of muscle cells. People living with DMD suffer from progressive muscle weakness that typically starts at a very young age. Over time, people with Duchenne will develop problems walking and breathing, and eventually, the heart and respiratory muscles will stop working. Those living with the condition often require special aid and assistance throughout their lives and have significantly shortened life expectancy. While there are treatments approved to treat people with DMD, there remains a very high unmet need. DMD is a monogenic, X-linked, recessive disease that primarily affects males, with one in 3,500 to 5,000 boys born worldwide having Duchenne. About AOC 1044 AOC 1044 is designed to deliver phosphorodiamidate morpholino oligomers (PMOs) to skeletal muscle and heart tissue to specifically skip exon 44 of the dystrophin gene to enable dystrophin production in people living with Duchenne muscular dystrophy with mutations amenable to exon 44 skipping (DMD44). DMD is characterized by progressive muscle degeneration and weakness due to alterations of a protein called dystrophin that protects muscle cells from injury during contraction. AOC 1044 consists of a proprietary monoclonal antibody that binds to the transferrin receptor 1 (TfR1) conjugated with a PMO targeting exon 44. In a preclinical model of DMD, a murine active AOC produced durable exon skipping and functional dystrophin protein in skeletal muscle and heart tissue following a single intravenous dose. AOC 1044 is currently in Phase 1/2 development as part of the EXPLORE44™ trial for the treatment of DMD mutations amenable to exon 44 skipping. Major Estimate Revision • Nov 29

Avidity Biosciences, Inc. Receives FDA Orphan Drug Designation for AOC 1020 for the Treatment of Facioscapulohumeral Muscular Dystrophy Avidity Biosciences, Inc. announced that the U.S. Food and Drug Administration (FDA) has granted Orphan Drug designation to AOC 1020 for the treatment of facioscapulohumeral muscular dystrophy (FSHD). FSHD is a serious, rare, hereditary muscle-weakening condition marked by life-long, progressive loss of muscle function that causes significant pain, fatigue, and disability. AOC 1020 is being evaluated in the Phase 1/2 FORTITUDE™ clinical trial in adults with FSHD and is the company's second muscle-targeting small interfering RNA (siRNA) AOC in clinical development. Avidity plans to share data from a preliminary assessment of AOC 1020 in approximately half of study participants from the FORTITUDE trial in the first half of 2024. The FDA's Office of Orphan Drug Products grants orphan status to support the development of medicines for rare disorders that affect fewer than 200,000 people in the U.S. Orphan drug designation provides certain benefits, including market exclusivity upon regulatory approval, exemption of FDA application fees, and tax credits for qualified clinical trials. About Facioscapulohumeral Muscular Dystrophy (FSHD): Facioscapulohumeral muscular dystrophy (FSHD) is characterized by progressive and often asymmetric skeletal muscle loss that typically causes weakness initially in muscles in the face, shoulders, arms and trunk and progresses to weakness in muscles in the lower body. FSHD is an autosomal dominant genetic disease. The abnormal expression of DUX4 (double homeobox 4) leads to a series of downstream events that result in skeletal muscle wasting and progressive loss of muscle function, including an inability to lift arms for more than a few seconds, loss of ability to show facial expressions, and serious speech impediments. These symptoms cause many people affected by FSHD to become dependent on the use of a wheelchair for mobility. Currently, there are no approved treatments for people living with FSHD. About AOC 1020: AOC 1020 is designed to treat the underlying cause of FSHD, which is caused by the abnormal expression of a gene called double homeobox 4 or DUX4. The abnormal expression of DUX4 protein leads to changes in gene expression in muscle cells that are associated with the life-long, progressive loss of muscle function in patients with FSHD. AOC 1020 aims to reduce the expression of DUX4 mRNA and DUX4 protein in muscles in patients with FSHD. AOC 1020 consists of a proprietary monoclonal antibody that binds to the transferrin receptor 1 (TfR1) conjugated with a siRNA targeting DUX4 mRNA. In preclinical studies, a single intravenous dose with the murine version of AOC 1020 prevented development of muscle weakness demonstrated by three functional assays - treadmill running, in vivo force and compound muscle action potential. AOC 1020 is currently in Phase 1/2 development as part of the FORTITUDE™ trial in adults with FSHD. Recent Insider Transactions Derivative • Feb 05

Avidity Biosciences, Inc. Announces Planned Explore44 Trial of AOC 1044 in Healthy Volunteers and Participants with Duchenne Muscular Dystrophy On October 13, 2022, Avidity Biosciences, Inc. announced its planned EXPLORE44 trial of AOC 1044 in healthy volunteers and participants with Duchenne muscular dystrophy. The EXPLORE44 trial is a randomized, placebo-controlled, double-blind, Phase 1/2 clinical trial to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamic effects of single and multiple ascending doses of AOC 1044 administered intravenously, with the primary objective being the safety and tolerability of AOC 1044 in adult healthy volunteers and pediatric and adult participants with DMD mutations amenable to exon 44 skipping. The EXPLORE44 trial will assess exon skipping and dystrophin protein levels in participants with DMD44 and will also explore measures of muscle function, patient-reported outcomes and quality of life. DMD44 is ultra rare, constituting approximately 7% of DMD patients, approximately 900 of which are in the United States. Participants with DMD44 will have the option to enroll in an extension study at the end of the treatment period in the EXPLORE44 trial. The overall development program for AOC 1044, which includes the EXPLORE44 trial and the extension study is designed to potentially support accelerated approval in the United States. In the second half of 2023, the Company plans to present results from the healthy volunteer portion of the EXPLORE44 trial. Preclinical studies showed that an antibody oligonucleotide conjugate approach targeting exon 23 in a murine model of DMD demonstrated exon skipping, dystrophin restoration and improved muscle function and serum biomarkers of muscle damage. Additionally, data from a preclinical study of AOC 1044 in patient-derived myotubes showed dose-dependent dystrophin restoration, and a preclinical study in non-human primate (“NHP”) observed dose-dependent exon skipping in skeletal and heart muscle with AOC 1044. In addition to the preclinical studies described above, Avidity completed an IND-enabling good laboratory practice (“GLP”) toxicology study of AOC 1044 in NHP. Results from the IND-enabling study showed that AOC 1044 was generally well tolerated and supported advancement into the clinic, with no dose limiting toxicity observed in NHP at the high dose tested. The study did not observe any treatment-related histopathologic toxicity, platelet or renal toxicity or any changes in safety pharmacology parameters (cardiac, respiratory and neurological). The high dose tested in both NHP and murine models was the maximum feasible dose and was the no-observed adverse effect level (“NOAEL”). Results of a nine-month chronic toxicology study of AOC 1044 in NHPs was consistent with the results of the IND-enabling study. Announcement • Oct 12
Avidity Biosciences, Inc. Announces Phase 1/2 EXPLORE44 Trial of AOC 1044 for Duchenne Muscular Dystrophy Mutations Amenable to Exon 44 Skipping Avidity Biosciences, Inc. announced the Phase 1/2 EXPLORE44 clinical trial of AOC 1044 in healthy volunteers and participants with Duchenne muscular dystrophy (DMD), a rare, genetic condition that is characterized by progressive muscle damage and weakness. AOC 1044 is designed for people living with DMD amenable to exon 44 skipping (DMD44) and is the first of multiple AOCs the company is developing for DMD. Currently, there are no approved therapies to treat the underlying mechanism of disease for people living with DMD mutations amenable to exon 44 skipping. Avidity has advanced three distinct rare disease programs - DM1, FSHD and DMD44 – into clinical development in a 14-month period. DMD is an irreversible, progressive disease caused by a genetic mutation that prevents the body from producing a protein called dystrophin, which is an important protein that protects muscle cells from injury during contraction. The lack of functional dystrophin leads to stress and tears of muscle cell membranes, resulting in muscle cell death and progressive loss of muscle function. Those living with the condition often require special aid and assistance throughout their lives and have significantly shortened life expectancy. AOC 1044 is designed to deliver phosphorodiamidate morpholino oligomers (PMO) to skeletal muscle and heart tissue to specifically skip exon 44 of DMD to enable dystrophin production. AOC 1044 is Avidity's first AOC engineered to deliver PMO and the company has two additional programs for DMD, which target exon 45 and exon 51. Avidity has three distinct rare disease programs in the clinic – AOC 1001 for myotonic dystrophy type 1 (DM1) is currently being evaluated in the MARINA™ Phase 1/2 clinical trial and an open label-extension trial called MARINA-OLE; AOC 1020 is advancing into the Phase 1/2 FORTITUDE trial for the treatment of facioscapulohumeral muscular dystrophy (FSHD) and AOC 1044 is advancing into the Phase 1/2 EXPLORE44 trial for the treatment of DMD44. The EXPLORE44 trial is a randomized, placebo-controlled, double-blind, Phase 1/2 clinical trial to evaluate AOC 1044 in healthy volunteers and participants with DMD mutations amenable to exon 44 skipping (DMD44). EXPLORE44 will evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamic effects of single and multiple ascending doses of AOC 1044 administered intravenously. EXPLORE44 is expected to enroll approximately 40 healthy volunteers and 24 participants with DMD44, ages seven to 27 years old. The EXPLORE44 trial will assess exon skipping and dystrophin protein levels in participants with DMD44. Participants with DMD44 will have the option to enroll into an extension study.

Avidity Biosciences Announces the Phase 1/2 Fortitude(Tm) Trial of AOC 1020 in Adults with Facioscapulohumeral Muscular Dystrophy Avidity Biosciences, Inc. announced the Phase 1/2 FORTITUDE(TM) clinical trial of AOC 1020 in adults with facioscapulohumeral muscular dystrophy (FSHD). FSHD is a rare, hereditary muscle-weakening condition marked by life-long, progressive loss of muscle function and causes significant pain, fatigue, and disability. AOC 1020 is the second muscle-targeting small interfering RNA (siRNA) AOC from Avidity's pipeline to advance into clinical development. Earlier this week, Avidity announced that the U.S. Food and Drug Administration (FDA) cleared the company's investigational new drug (IND) applications of AOC 1020 for FSHD and AOC 1044 for the treatment of Duchenne muscular dystrophy (DMD) mutations amenable to exon 44 skipping (DMD44). The company has now advanced three programs - DM1, FSHD and DMD44 -- into clinical development in a 14-month period. Announcement • Sep 28
Avidity Biosciences, Inc. Announces FDA Partial Clinical Hold on New Participant Enrollment in Phase 1/2 MARINA™ Trial Avidity Biosciences, Inc. announced that the U.S. Food and Drug Administration (FDA) has placed a partial clinical hold on new participant enrollment in the Phase 1/2 MARINA™ clinical trial of AOC 1001 in adults with myotonic dystrophy type 1 (DM1). Close to 40 participants are currently enrolled in the MARINA and MARINA open label extension (MARINA-OLE™) trials. All participants, whether they are on AOC 1001 or placebo, may continue in their current dosing cohort although no additional participants may be enrolled until the partial clinical hold is resolved. All participants in MARINA may roll over into the MARINA-OLE where they will receive AOC 1001 as planned. DM1 is an underrecognized, progressive and often fatal neuromuscular disease with no approved treatment options. The partial clinical hold is in response to a serious adverse event reported in a single participant in the 4mg/kg cohort of the MARINA study. Avidity is working closely with the FDA and the trial investigator to assess the cause of this event. The company is taking all necessary steps to resolve the partial clinical hold on new participant enrollment as quickly as possible. Avidity remains on track to conduct a preliminary assessment of safety, tolerability and key biomarkers in approximately half of the study participants in the MARINA trial in the fourth quarter of 2022. Avidity received IND clearance from the FDA to proceed with the clinical trial of AOC 1020 for the treatment of facioscapulohumeral muscular dystrophy (FSHD) and AOC 1044 for the treatment of Duchenne muscular dystrophy (DMD) with mutations amenable to exon 44 skipping. These programs are now advancing into the clinic. Recent Insider Transactions Derivative • Aug 27

Avidity Biosciences, Inc. Enrolls Patients in the Marina(Tm) Open-Label Extension Study Avidity Biosciences, Inc. announced that it has commenced enrolling patients from the Phase 1/2 MARINA(TM) study into a Phase 2 open-label extension study (MARINA-OLE(TM)) of AOC 1001 in adults with myotonic dystrophy type 1 (DM1). All patients enrolled in the randomized, placebo-controlled MARINA(TM) clinical trial with AOC 1001 are eligible to enroll in MARINA-OLE. DM1 is an underrecognized, progressive and often fatal neuromuscular disease. It primarily affects skeletal and cardiac muscle with multiple organ involvement and can be highly variable with respect to severity, presentation, and age of onset. There are currently no disease-modifying treatments for people 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 DMPK, the disease-related mRNA. AOC 1001 consists of a proprietary monoclonal antibody that binds to the transferrin receptor 1 (TfR1) conjugated with a small interfering RNA (siRNA). The U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA) have granted Orphan Designation for AOC 1001 and the FDA has granted AOC 1001 Fast Track Designation. About the Phase 2 MARINA-OLE(TM) Study MARINA-OLE(TM) is an open-label, multi-center study designed to evaluate the long-term safety and tolerability of AOC 1001 in DM1 patients who were previously enrolled in the MARINA Phase 1/2 study. This study will continue to evaluate the safety, tolerability, PK, PD, and efficacy of AOC 1001 in patients that enrolled in the randomized, placebo-controlled, Phase 1/2 MARINA clinical study. Patients who enroll in the MARINA-OLE study will receive quarterly doses of AOC 1001 regardless of whether they received active treatment or placebo in the MARINA study. The total duration of active treatment with AOC 1001 in the MARINA-OLE is approximately 24 months. Once patients have completed active treatment, there will be a 9-month safety follow-up period. Avidity may extend active treatment beyond 24 months at a future timepoint. Announcement • Jun 26

Avidity Biosciences, Inc. Supports World Facioscapulohumeral Muscular Dystrophy Day and Presents Preclinical Data from FSHD Program Avidity Biosciences, Inc. called Antibody Oligonucleotide Conjugates, joins in activities to raise awareness for Facioscapulohumeral muscular dystrophy in support of World FSHD Day and highlights preclinical results supporting AOC 1020 for the treatment of FSHD at the 29th Annual FSHD Society International Research Congress (FSHD IRC) in Orlando, Florida. Currently, there are no approved therapies for the treatment of FSHD. FSHD is a rare, hereditary muscle-weakening condition that affects approximately 16,000-38,000 people in the United States. It is marked by life-long, progressive loss of muscle function and causes significant pain, fatigue, and disability. FSHD is an autosomal dominant disease caused by the abnormal expression of DUX4 (double homeobox 4), a gene involved in embryonic development but not typically expressed in muscles. This abnormal expression of DUX4 leads to a series of downstream events that result in skeletal muscle wasting and compromised muscle function with onset often in teenage and early adult years. Every June 20th, people around the world join in activities to raise awareness for FSHD through World FSHD Day and to recognize patients and families around the world who are affected by FSHD. To mark FSHD awareness day, Avidity is participating in the FSHD IRC as well as the FSHD Connect Conference, an educational conference specifically for people living with FSHD and their families. Both conferences are being held in Orlando, Florida and organized by the FSHD Society, the world's largest research-focused patient organization for FSHD. On June 17, 2022, Avidity will share preclinical data from the FSHD program during a presentation at the FSHD IRC. Studies were conducted in mouse models of FSHD that are genetically engineered to express human DUX4 in skeletal muscle. AOC 1020 is comprised of a DUX4-targeting siRNA conjugated to the human anti-transferrin receptor 1 monoclonal antibody. The preclinical studies were done using a monoclonal antibody suitable for mice. The preclinical data provides support for AOC 1020 to enter the clinic for the treatment of FSHD by end of 2022. Key highlights from the oral presentation include: Data from a study conducted to assess pharmacology in the mouse model of FSHD showed robust dose-dependent down regulation of DUX4 genes in skeletal muscle for 8 weeks following a single intravenous (IV) dose of the murine version of AOC 1020. Data from a study designed to assess phenotype development in the FSHD mouse model showed that a single IV treatment with the murine version of AOC 1020 prevented muscle weakness development demonstrated by three functional assays - treadmill running, in vivo force and compound muscle action potential. Avidity is also presenting data from a real-world data analysis of patients with FSHD before and after their diagnosis. The results highlight the increased morbidity and medical and financial burden patients face as they progress through their journey living with FSHD. Major Estimate Revision • May 17
