FSHD Society to host Avidity webinar on positive initial data from the Phase 1/2 FORTITUDE™ trial for people living with FSHD today at 1:00 p.m. ET
SAN DIEGO, June 20, 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 announced it is partnering with the FSHD Society and joining the global community of patients, caregivers, and healthcare providers to raise awareness of facioscapulohumeral muscular dystrophy in support of World FSHD Day. The FSHD Society is hosting a webinar with Avidity today at 1:00 p.m. ET to share recent unprecedented del-brax data from its Phase 1/2 FORTITUDE™ trial in people living with FSHD, a rare, hereditary disorder marked by life-long, relentless loss of muscle function, significant pain, fatigue, and progressive disability.
"This World FSHD Day, we are excited to be joining the FSHD Society to share recent unprecedented data from our FORTITUDE study with the patient and caregiver community," said Sarah Boyce, president and chief executive officer at Avidity. "We know the FSHD community is eagerly waiting for an approved therapy and we are committed to bringing forward a treatment as quickly as possible to the many families worldwide who are affected by FSHD. We are extremely thankful for the important contributions of patients, caregivers and families that continue to better inform our ongoing research and development as we advance del-brax for people living with FSHD."
"As the world's largest research-focused patient organization, we are dedicated to speeding the delivery of treatments and a cure for FSHD. With the remarkable data from Avidity's FORTITUDE study presented last week, we feel invigorated that there may be a potential treatment to change the course of this relentlessly progressive disease for people and families affected by FSHD," said Mark Stone, president and chief executive officer of FSHD Society. "We remain deeply committed to our collaborations with industry leaders such as Avidity who are accelerating innovative research. World FSHD Day is an important opportunity to recognize the partnership, commitment and work that is necessary to bring more support and more hope to families impacted by FSHD every day."
In the Phase 1/2 study, del-brax, the first investigational therapy designed to treat the underlying cause of FSHD, demonstrated 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 FSHD. Currently, there are no approved therapies for the treatment of FSHD.
In an online webinar today hosted by the FSHD Society, the Avidity team, joined by Dr. Jeffrey Statland, University of Kansas Medical Center and FORTITUDE trial investigator, will present the FORTITUDE trial initial findings, focusing on what these results mean for the FSHD community.
Date: Thursday, June 20, 2024
Time: 10:00 a.m. Pacific Time / 1:00 p.m. Eastern Time
How to join: You can register to join the webinar on the FSHD Society's website (https://www.fshdsociety.org/event/fshd-university-fortitude-trial-interim-results/). A recording of this webinar will be available on FSHD Society's FSHD University at a later date.
Every June 20th, people around the world join in activities to raise awareness of FSHD through World FSHD Day and to recognize patients and families worldwide who are affected by FSHD. This year, Avidity participated in the 31st Annual FSHD Society International Research Congress (FSHD IRC), where Jeffrey M. Statland, M.D., Professor of Neurology, University of Kansas Medical Center, and FORTITUDE trial investigator, presented the new initial data from the FORTITUDE study. Avidity also participated in the FSHD Connect Conference, an educational conference specifically for people living with FSHD and their families. Both conferences are organized by the FSHD Society, the world's largest research-focused patient organization for FSHD.
About the Phase 1/2 FORTITUDE™ trial
The FORTITUDE™ trial is a randomized, placebo-controlled, double-blind, Phase 1/2 clinical trial designed to evaluate single and multiple doses of delpacibart braxlosiran or del-brax (AOC 1020) in approximately 39 adult participants with facioscapulohumeral muscular dystrophy (FSHD). FORTITUDE will evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of del-brax administered intravenously, with the primary objective being the safety and tolerability of del-brax in FSHD patients. Activity of del-brax will be assessed using key biomarkers, including magnetic resonance imaging (MRI) measures of muscle volume and composition. Though the Phase 1/2 trial is not statistically powered to assess functional benefit, it will explore the clinical activity of del-brax including measures of mobility and muscle strength as well as patient reported outcomes and quality of life measures. Participants will have the option to enroll in an open-label extension study at the end of the treatment period in the FORTITUDE study.

About Del-brax (AOC 1020)
Del-brax (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. Del-brax aims to reduce the expression of DUX4 mRNA and DUX4 protein in muscles in people with FSHD. Del-brax 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 del-brax prevented development of muscle weakness demonstrated by three functional assays - treadmill running, in vivo force and compound muscle action potential. Del-brax is currently in Phase 1/2 development as part of the FORTITUDE™ trial in adults with FSHD. The U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) have granted Orphan designation for del-brax and the FDA has granted del-brax Fast Track designation.
About Facioscapulohumeral Muscular Dystrophy (FSHD)
Facioscapulohumeral muscular dystrophy (FSHD) is a rare, progressive, and variable hereditary muscle-weakening condition marked by significant pain, fatigue, and disability. It is characterized by progressive and often asymmetric skeletal muscle loss that initially causes weakness in muscles in the face, shoulders, arms and trunk and progresses to weakness in muscles in the lower body. FSHD is an autosomal dominant disease caused by the aberrant expression of the DUX4 (double homeobox 4) gene in the skeletal muscle, which activates genes that are toxic to muscle cells and leads to a series of downstream events that result in skeletal muscle wasting and compromised muscle function. Skeletal muscle weakness results in physical limitations throughout the whole body, 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.
