CAMBRIDGE, Mass., May 05, 2016 (GLOBE NEWSWIRE) -- Agios Pharmaceuticals, Inc. (NASDAQ:AGIO), a leader in the fields of cancer metabolism and rare genetic metabolic disorders, today reported business highlights and financial results for the first quarter ended March 31, 2016.

"We have been focused on executing against the important milestones we laid out in January, and I'm proud of the progress across both our cancer and rare genetic disorders programs to date," said David Schenkein, M.D., chief executive officer at Agios. "Notably, enrollment is complete ahead of schedule for the Phase 2 expansion cohort for the Phase 1/2 study of AG-221 in advanced AML. This achievement is crucial to getting this potential new therapy to patients as quickly as possible.

FIRST QUARTER 2016 FINANCIAL RESULTS

Cash, cash equivalents and marketable securities as of March 31, 2016 were $355.8 million, compared to $375.9 million as of December 31, 2015. The decrease was driven by cash expenditures to fund operating activities of $54.1 million, which was offset by funding of $35.1 million from Celgene during the quarter ended March 31, 2016 related to our collaboration agreements.

Collaboration revenue was $31.3 million for the quarter ended March 31, 2016, compared to $34.2 million for the comparable period in 2015. In the first quarter of 2016, the Company received and recognized as revenue $25.0 million related to a substantive clinical development milestone for the AG-221 program.

Research and development (R&D) expense was $44.0 million, including $5.5 million of stock-based compensation expense, for the quarter ended March 31, 2016, compared to $32.4 million, including $2.6 million in stock-based compensation expense, for the quarter ended March 31, 2015. The increase in R&D expense was primarily due to increased costs to support advancement of the company's lead investigational medicines toward later-stage development. Celgene is responsible for all development costs for AG-221 and certain development costs for AG-120 and AG-881 and reimburses the company for development costs incurred for these investigational medicines.

General and administrative (G&A) expense was $10.8 million, including $3.6 million of stock-based compensation expense, for the quarter ended March 31, 2016, compared to $7.0 million, including $2.4 million of stock-based compensation expense, for the quarter ended March 31, 2015. The increase in G&A expense was largely due to increased headcount and other professional expenses to support growing operations.

Net loss for the quarter ended March 31, 2016 was $23.2 million, compared to a net loss of $5.0 million for the quarter ended March 31, 2015.
