SAN DIEGO, May 11, 2016 /PRNewswire/ -- 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 operating results for the first quarter ended March 31, 2016.

First Quarter Results  

Research and development expenses were $12.0 million and $6.6 million for the quarters ended March 31, 2016 and 2015, respectively. The increase of $5.4 million was due primarily to a $5.8 million increase related to manufacturing costs and clinical and non-clinical development costs incurred in support of various activities for Resolaris™ and a $0.9 million increase related to compensation expenses resulting from increased headcount in research and development functions, including $0.2 million in non-cash stock-based compensation. The increase was offset by a decrease related to a one-time $1.4 million non-cash expense for the assignment of certain intellectual property rights in the prior year period.

General and administrative expenses were $4.1 million and $2.3 million for the quarters ended March 31, 2016 and 2015, respectively.  The increase of $1.8 million was due primarily to a $1.6 million increase in personnel costs resulting from increased headcount inclusive of $0.5 million in non-cash stock-based compensation. 

Recent Highlights

The company is also pleased to announce that it has completed enrollment of its Phase 1b/2 clinical trial testing Resolaris in patients with limb-girdle muscular dystrophy 2B (LGMD2B or dysferlinopathies) or facioscapulohumeral muscular dystrophy (FSHD).  Data from this clinical trial is expected to be announced in the fourth quarter of this year.
