Street Calls of the Week
Avidity Biosciences, Inc. (NASDAQ:RNA), with a market capitalization of $5.75 billion, is emerging as a notable player in the rare disease therapeutics space, with a focus on developing innovative treatments for muscular dystrophies. The company’s stock has garnered significant attention from analysts due to its promising pipeline and potential to address substantial unmet medical needs. According to InvestingPro data, RNA has shown strong momentum with a 31% gain over the past six months, though current analysis suggests the stock may be trading above its Fair Value.
Company Overview and Recent Performance
Avidity Biosciences is a clinical-stage biopharmaceutical company dedicated to developing therapies for rare, severe muscle diseases. The company’s proprietary Antibody Oligonucleotide Conjugate (AOC) platform technology combines the tissue selectivity of monoclonal antibodies with the precision of oligonucleotide therapies to target underlying genetic drivers of diseases.
The company’s stock has experienced volatility in recent months, reflecting both the potential of its pipeline and the inherent risks associated with clinical-stage biotechnology companies. As of September 18, 2025, Avidity’s shares were trading at $47.23, significantly below the most optimistic analyst targets but showing resilience in a challenging market for biotech stocks.
Main Programs and Pipeline
Avidity’s pipeline is anchored by three lead candidates, each targeting a different muscular dystrophy:
1. Del-zota (AOC 1044) for Duchenne Muscular Dystrophy (DMD) exon 44 skipping
2. Del-desiran for Myotonic Dystrophy Type 1 (DM1)
3. Del-brax for Facioscapulohumeral Muscular Dystrophy (FSHD)
These programs represent potentially first- and best-in-class assets, addressing large patient populations with significant unmet medical needs.
Clinical Progress and Regulatory Outlook
Del-zota, the company’s most advanced program, has shown promising results in dystrophin production and creatine kinase (CK) reductions in DMD patients. Analysts anticipate a potential Biologics License Application (BLA) filing by the end of 2025 in the United States.
The del-desiran program for DM1 has demonstrated sustained benefits in myotonia and muscle function. A Phase 3 trial is currently underway, with a BLA submission expected in the second half of 2026.
Del-brax, targeting FSHD, has shown disease-modifying potential. Pivotal biomarker cohort data is expected in the second quarter of 2026, with a possible BLA submission following in the second half of that year.
Analysts are particularly optimistic about the potential for accelerated approval pathways for both the FSHD and DM1 programs. The company is in ongoing discussions with the FDA regarding these possibilities, which could significantly expedite the path to market for these therapies.
Financial Position
As of the first quarter of 2025, Avidity reported a strong cash position of $1.4 billion, which is expected to fund operations into mid-2027. This robust financial standing provides the company with ample runway to advance its clinical programs and prepare for potential commercialization. InvestingPro analysis confirms this financial strength, showing the company holds more cash than debt and maintains a healthy current ratio of 9.26, indicating strong liquidity to meet short-term obligations.
Despite the healthy cash reserves, Avidity continues to report net losses, which is typical for clinical-stage biotech companies. Analysts project negative earnings per share for the near term, with estimates of -6.26 for fiscal year 2025 and -7.31 for fiscal year 2026.
Market Opportunity
The potential market for Avidity’s therapies is substantial. Analysts suggest that sales could approach $10 billion at peak if all three lead assets are approved. Specifically, del-zota’s U.S. sales for DMD are projected to reach approximately $400 million. Current revenue stands at $10.73 million, highlighting the significant growth potential ahead.

The FSHD market alone is estimated to be worth $4-5 billion, highlighting the significant commercial opportunity for del-brax if approved. The DMD and DM1 markets also represent substantial opportunities, given the high unmet need and limited treatment options currently available.
Bear Case
How might potential safety concerns impact the regulatory pathway for Avidity’s candidates?
Safety remains a primary concern for Avidity’s programs, particularly given the history of a partial clinical hold on the DM1 program. While recent data has been encouraging, any emerging safety signals could significantly delay or derail the regulatory process. The FDA’s scrutiny of novel therapies, especially those targeting rare diseases, is intense, and any safety issues could lead to additional studies or even program termination.
What challenges could Avidity face in commercializing its therapies in competitive rare disease markets?
Despite the potential for first-in-class therapies, Avidity will likely face competition from other companies developing treatments for muscular dystrophies. Established players and emerging biotechs are all vying for a share of these markets. Avidity will need to demonstrate clear superiority or differentiation to gain market share and secure favorable reimbursement. Additionally, the complexities of rare disease markets, including patient identification and access to treatment centers, could pose challenges to commercial success.
Bull Case
How could successful development of multiple first-in-class therapies position Avidity in the rare disease space?
If Avidity succeeds in bringing multiple first-in-class therapies to market, it could establish itself as a leader in the rare disease space, particularly in muscular dystrophies. This would not only drive significant revenue but also validate the company’s AOC platform technology, potentially opening doors for expansion into other rare diseases. Success across multiple indications could also attract partnership opportunities or make Avidity an attractive acquisition target for larger pharmaceutical companies looking to bolster their rare disease portfolios.
What impact could accelerated approval pathways have on Avidity’s timeline to market and financial outlook?
Securing accelerated approval pathways for del-brax in FSHD and del-desiran in DM1 could dramatically shorten the time to market for these therapies. This would allow Avidity to start generating revenue sooner, potentially reaching profitability earlier than currently projected. Accelerated approvals would also likely boost investor confidence, potentially driving up the stock price and making it easier for the company to raise additional capital if needed. Moreover, early entry into these markets could help Avidity establish a strong foothold before competitors arrive.
