aTyr Pharma Receives EMA Orphan Drug Designation for the Treatment of Limb Girdle Muscular Dystrophy

aTyr Pharma, Inc , a biotherapeutics company engaged in the discovery and development of Physiocrine-based therapeutics to address severe, rare diseases announced that the EMA has granted orphan drug designation to Resolaris™ for the treatment of LGMD patients.

“As the week of International Rare Disease day concludes, we remind ourselves of our important mission to our patients – to develop new medicines based on our pioneering efforts in Physiocrine biology that we hope form the basis of meaningful changes to the lives of patients impacted by rare diseases worldwide. We are encouraged that the EMA has recognized the potential of Resolaris for LGMD patients,” said John Mendlein, CEO of aTyr Pharma.

“The Resolaris program has now been granted Orphan Drug Designation for both LGMD and facioscapulohumeral muscular dystrophy (FSHD) from the FDA and the EMA, as well as Fast Track designation for both rare myopathies with an immune component from the FDA. We are pleased with the development of Resolaris from a clinical and regulatory standpoint. We look forward to continuing to develop this potential therapy to help treat patients with these rare myopathies, for which there are limited or no treatment options, across the globe.”

EMA orphan designation is intended to encourage development of medicines for the diagnosis, treatment, or prevention of life-threatening or chronically debilitating conditions that affect no more than 5 in 10,000 people in the EU. Medicines that receive orphan designation are eligible for a number of incentives, including assistance with development of the medicine; reduced fees for marketing-authorization applications; and extended market exclusivity once the medicine is authorized. Orphan designation is conferred following a positive opinion by the EMA’s Committee for Orphan Medicinal Products (COMP).

About Resolaris™
aTyr Pharma is developing Resolaris as a potential first-in-class intravenous protein therapeutic for the treatment of rare myopathies with an immune component. Resolaris is derived from a naturally occurring protein released by human skeletal muscle cells. aTyr believes Resolaris has the potential to provide therapeutic benefit to patients with rare myopathies with an immune component characterized by excessive immune cell involvement.

About LGMD2B
Limb girdle muscular dystrophy (LGMD) refers to a group of rare genetic myopathies, of which there are more than 20 different subtypes, none with approved therapies. LGMD affects an estimated 16,000 patients in the U.S., approximately 3,000 of whom have LGMD2B. LGMD2B is a recessive genetic disease caused by a toxic loss of function in the dysferlin gene. Patients experience progressive debilitating muscle weakness and atrophy as well as immune cell invasion in the skeletal muscle. To learn more about LGMD2B please visit www.jain-foundation.org.
