Facioscapulohumeral Muscular Dystrophy: Understanding

Facioscapulohumeral Muscular Dystrophy: Overview

Facioscapulohumeral muscular dystrophy (FSHD) typically presents with weakness of the facial muscles, the stabilizers of the scapula, or the dorsiflexors of the foot. Severity is highly variable. Weakness is slowly progressive and approximately 20% of affected individuals eventually require a wheelchair. Life expectancy is not shortened.

Two types of FSHD have been described, FSHD1 (95% of those affected) and FSHD2 (5% of those affected). FSHD1 and FSHD2 have the same signs and symptoms but different genetic causes. FSHD1 is inherited in an autosomal dominant manner. Approximately 70%-90% of individuals have inherited the disease-causing deletion from a parent, and approximately 10%-30% of affected individuals have FSHD as the result of a de novo deletion. Offspring of an affected individual have a 50% chance of inheriting the deletion. Prenatal testing for a pregnancy at increased risk is possible if the D4Z4 pathogenic contraction has been identified in the family. FSHD2 is inherited in a digenic manner.

In around 90% of FSHD patients, symptoms usually begin before age 20, with weakness and atrophy of the muscles around the eyes and mouth, shoulders, abdominal muscles, upper arms, and lower legs, usually with asymmetric involvement.

Some experts divide FSHD into adult-onset and infantile-onset forms. The adult-onset (which includes FSHD that begins in adolescence) is far more common. In either type of FSHD, facial weakness can start in childhood. Occasionally, other FSHD symptoms appear in early childhood.

Infantile-onset FSHD generally runs a more pronounced course with regard to muscle weakness, and sometimes also affects hearing and vision. Preliminary evidence suggests that the infantile-onset form is associated with a larger piece of missing DNA.

The diagnosis of FSHD1 is established in a proband with characteristic clinical features by identification of a heterozygous pathogenic contraction of the D4Z4 repeat array in the subtelomeric region of chromosome 4q35 on a chromosome 4 permissive haplotype. The diagnosis of FSHD2 is established in a proband by identification of hypomethylation of the D4Z4 repeat array in the subtelomeric region of chromosome 4q35 on a chromosome 4 permissive haplotype. Hypomethylation of the D4Z4 repeat array can be the result of a heterozygous pathogenic variant in SMCHD1 or DNMT3B.

Consultation with a physical therapist to establish appropriate exercise regimen; ankle/foot orthoses to improve mobility and prevent falls; occupational and speech therapy in individuals with infantile onset; surgical fixation of the scapula to the chest wall may improve range of motion of the arms over the short term; management of chronic pain by physical therapy and medication; monitoring respiratory function; lubricants to prevent drying of the sclera or taping the eyes shut during sleep to treat exposure keratitis; treatment for retinal vasculopathy as per ophthalmologist; standard treatment of sensorineural hearing loss.

Surveillance: Annual physical therapy assessment; Pain should be assessed at regular visits to the primary care physician or physical therapist; screening for hypoventilation in individuals with abnormal PFTs, severe proximal weakness, kyphoscoliosis, wheelchair dependence, or comorbid disease affecting ventilation; pulmonary consultation for FVC <60%, excessive daytime somnolence or nonrestorative sleep, and prior to surgical procedures requiring anesthesia; annual dilated ophthalmoscopy in individuals with early childhood-onset FSHD with large pathogenic contraction of D4Z4 and adults with visual symptoms; audiometry in infants at each visit and annually in children.

Facioscapulohumeral Muscular Dystrophy Emerging Drugs Chapters

This segment of the Facioscapulohumeral Muscular Dystrophy report encloses its detailed analysis of various drugs in different stages of clinical development, including phase II, I, preclinical and Discovery. It also helps to understand clinical trial details, expressive pharmacological action, agreements and collaborations, and the latest news and press releases.

Facioscapulohumeral Muscular Dystrophy Emerging Drugs

• Losmapimod: Fulcrum Therapeutics

Losmapimod is an investigational, selective p38a/B mitogen activated protein kinase (MAPK) inhibitor. Fulcrum exclusively in-licensed losmapimod from GSK following Fulcrum's discovery of the role of p38a/B inhibitors in the reduction of DUX4 expression and an extensive review of known compounds. Results reported from the ReDUX4 trial demonstrated slowed disease progression and improved function, including positive impacts on upper extremity strength, supporting losmapimod's potential to be a transformative therapy for the treatment of FSHD. Although losmapimod had never previously been explored in muscular dystrophies, it had been evaluated in more than 3,600 subjects in clinical trials across multiple other indications, with no safety signals attributed to losmapimod.

Losmapimod has been granted FDA Fast Track designation and Orphan Drug Designation for the treatment of FSHD. Fulcrum Therapeutics intends to submit regulatory application to the US FDA and EMA in Facioscapulohumeral muscular dystrophy. The drug is currently in Phase III stage of development for the treatment of facioscapulohumeral muscular dystrophy (FSHD).

• DYNE-301: Dyne Therapeutics

DYNE-301 is a DUX4L1 protein expression stimulant, which consists of company's proprietary Fab conjugated with our linker to an ASO that is designed to address the genetic basis of FSHD by reducing DUX4 expression in muscle tissue. Proof-of-concept data showing that DYNE-301 reduced expression of key DUX4 biomarkers in FSHD patient myotubes, a type of muscle cell. Currently the product is in preclinical stage of development for the disease.
