The $12.5 billion acquisition of Avidity Biosciences Inc. by Novartis AG strengthens the company’s neuroscience pipeline and marks the second biggest deal that’s been announced this year. It also is the fifth M&A deal in the past five weeks to top the $1 billion mark, a sign that the market may be strengthening.
As Avidity Biosciences Inc. brought the second-largest follow-on offering of the year to the market, the company also released positive early and midstage stage results of del-zota, an antibody-oligonucleotide conjugate, in treating Duchenne muscular dystrophy. Phase I/II results showed a reversal of disease progression in patients who have been continuously treated for a year, plus improvements in several functional measures.
The revised trial protocol that means a delay in filing for U.S. approval of DYNE-101 to treat myotonic dystrophy type 1 (DM1) dented shares of Dyne Therapeutics Inc. (NASDAQ:DYN), which closed June 17 at $10.86, down $2.96, or 21%.
While data on functional endpoints are still to come, Avidity Biosciences Inc. executives said the firm is moving ahead with plans for a BLA filing by the end of 2025 for del-zota, an antibody-oligonucleotide conjugate, in Duchenne muscular dystrophy with mutations amenable to exon 44 skipping (DMD44), based on positive top-line data that analysts say bode well for Avidity’s other late-stage programs targeting rare neuromuscular diseases.
Avidity Biosciences Inc. has announced two new precision cardiology development candidates targeting rare genetic cardiomyopathies. AOC-1086 targets phospholamban (PLN) cardiomyopathy and AOC-1072 targets protein kinase AMP-activated noncatalytic subunit γ2 (PRKAG2) syndrome.
After missing the primary and secondary endpoints in its phase III study of losmapimod in treating the rare disease facioscapulohumeral muscular dystrophy (FHSD), Fulcrum Therapeutics Inc. is yanking the program’s plug. The selective p38α/β mitogen activated protein kinase inhibitor had a lot of money behind it. It was originally in-licensed from GSK plc and then, in May, Sanofi SA signed on to help Fulcrum develop and commercialize losmapimod for FHSD worldwide, excluding the U.S., in a deal worth $1.06 billion.
The good news for Sarepta Therapeutics Inc. is bad news for Pfizer Inc. as the phase III study of its mini-dystrophin gene therapy in Duchenne muscular dystrophy (DMD) has missed its primary endpoint. Now Sarepta’s Elevidys (delandistrogene moxeparvovec), a single-dose, adeno-associated virus-based gene transfer therapy for DMD, is barreling toward a June 21 PDUFA date with the U.S. FDA as the near competition shrinks in the rearview mirror.
Shares of Avidity Biosciences Inc. hit a 52-week high on reports of promising data from the first efficacy cohort of its phase I/II Fortitude study testing delpacibart braxlosiran (del-brax) in facioscapulohumeral muscular dystrophy (FSHD), including impressive biomarker results that could indicate a path for potential accelerated approval.
Fulcrum Therapeutics Inc.’s deal with Sanofi SA to develop and commercialize oral losmapimod shone more light on facioscapulohumeral muscular dystrophy (FSHD), a rare genetic disease where Avidity Biosciences Inc. also has an earlier-stage but high-profile program.
In a deal that could bring Avidity Biosciences Inc. $2.3 billion if all milestones are met, Bristol Myers Squibb Co. gained global rights to Avidity’s antibody oligonucleotide conjugates platform to advance up to five genetic cardiovascular targets. Avidity’s technology, which combines the specificity of monoclonal antibodies with the precision of oligonucleotide therapies, aims to address the root cause of diseases that are untreatable with current RNA therapeutics. Its lead internal programs are based on the targeted delivery of RNA into muscle.
