Shares of Avidity Biosciences Inc. (NASDAQ:RNA) dropped 15% March 30 as the company disclosed details of the serious adverse event (SAE) that prompted a partial clinical hold in September 2023 on the phase I/II trial testing AOC-1001 in adults with myotonic dystrophy type 1 (DM1).
Partially blocking a receptor that helps regulate the activity of the inflammatory cytokine molecule interleukin-6 (IL-6) seems to promote tissue regeneration and block degeneration in a model of osteoarthritis. As reported in the March 22, 2023, issue of Science Translational Medicine, the receptor, called glycoprotein 130 (gp130), regulates both positive and negative inflammatory responses that can help regenerate tissue, but also cause degeneration.
Tofersen’s development is progressing in fits and starts. That was evident at the U.S. FDA’s March 22 meeting of the Peripheral and Central Nervous System Drugs Advisory Committee, which unanimously agreed Biogen Inc.’s failed phase III study predicted a clinical benefit in treating amyotophic lateral sclerosis (ALS) that includes the rare superoxide dismutase 1 component.
Despite a failed phase III study, the U.S. FDA suggests in briefing documents that tofersen (BIIB-067) is effective for treating the rare, genetic disease superoxide dismutase 1 amyotrophic lateral sclerosis (ALS). The intrathecally injected therapy is being developing by Biogen Inc. and Ionis Pharmaceuticals Inc. and is at the heart of a March 22 meeting of the agency’s Peripheral and Central Nervous System Drugs Advisory Committee (adcom).
Quralis Inc. raised $88 million in series B round to fund clinical development of its two lead programs in amyotrophic lateral sclerosis (ALS) and to take forward earlier-stage pipeline projects in ALS and frontotemporal dementia.
Newco Relation Therapeutics Ltd. is showing its colors after raising $25 million in a seed round to work on integrating single cell transcriptomics, functional genomics and machine learning – and cut through previously undecipherable combinatorial space – to find and validate drug targets in the non-coding genome.
Juvena Therapeutics Inc. co-founder and CEO Hanadie Yousef had the company’s name picked out several years before it was officially incorporated in 2017 to combine Yousef’s work in the mechanics of aging with an underutilized class of biologics and an advanced proteomics platform to tackle chronic and age-related diseases.
The first in vivo cell atlas of senescent tissue in skeletal muscle has identified the damaging properties of these cells and explained why they block muscle regeneration. According to a study at Pompeu Fabra University led by scientists from Altos Labs Inc., cell damage caused the senescence of the cells, which secreted toxic substances into the surrounding microenvironment, causing fibrosis and preventing tissue regeneration.
A preliminary assessment of Avidity Biosciences Inc.’s phase I/II study of AOC-1001 in myotonic dystrophy type 1 (DM1) showed the first-ever targeted delivery of RNA into muscle, an area previously untreatable with existing RNA therapeutics. Sarah Boyce, Avidity’s CEO, said in a Dec. 14 call that the antibody oligonucleotide conjugate’s data were unprecedented in the RNA space and in myotonic dystrophy type 1 (DM1), labeling it a “revolutionary advancement.”
Ascidian Therapeutics Inc. secured $50 million in series A funding from its founder Apple Tree Partners to take a therapy based on its RNA exon editing technology into a first-in-human trial in ABCA4 retinopathy and to advance additional programs in neuromuscular, neurological, and rare disease indications.
