SAN DIEGO, April 24, 2017 (GLOBE NEWSWIRE) -- aTyr Pharma, Inc. (Nasdaq:LIFE), a biotherapeutics company engaged in the discovery and development of Physiocrine-based therapeutics to address severe, rare diseases, today announced its participation as part of the Emerging Science Platform Session at the upcoming American Academy of Neurology (AAN) 69th Annual Meeting to be held April 22 – 28, 2017 in Boston, MA.

Details of the session are below:

Emerging Science Platform Session: Tuesday, April 25, 2017 from 5:45 p.m. – 7:15 p.m. (ET)

  • Title: Results of a Phase 1b/2 Study of ATYR1940 in Adult Patients with Limb Girdle Muscular Dystrophy Type 2B (LGMD2B) and Facioscapulohumeral Muscular Dystrophy (FSHD) (ATYR1940-C-004) 
  • Author and Presenter: John Vissing, M.D., Ph.D., Professor of Neurology, University of Copenhagen
  • Supporting Authors: Attarian S., Gidaro T., Mozaffar T., Iyadurai S., Walker G., Shukla, S., Servais, L., Wagner, K.
  • Location: Boston Convention and Exhibition Center, 415 Summer St., Boston, MA

The poster presentation provides further detail on the previously announced results from the completed Phase 1b/2 open-label, intra-patient dose escalation 004 trial testing doses of Resolaris (ATYR1940) of up to 3.0 mg/kg biweekly in patients with LGMD2B and FSHD. Data from all clinical trials completed to date demonstrate that Resolaris has a favorable safety profile and was generally well-tolerated across all doses tested. There have been no observed signs of general immunosuppression and low-level anti-drug antibody signals did not result in clinical symptoms. 78% of the LGMD2B patients in the trial recorded increases in muscle function at 14 weeks as measured by manual muscle test (MMT) score, a validated assessment tool. 50% of the FSHD patients in the trial recorded increases in muscle function as measured by MMT score.

aTyr believes these data are supportive of further advancement of Resolaris.
