Phase 1 Expansion Studies for AG-221 & AG-120 Programs Ongoing

CAMBRIDGE, Mass., Aug. 6, 2015 (GLOBE NEWSWIRE) -- Agios Pharmaceuticals (NASDAQ:AGIO), a leader in the fields of cancer metabolism and rare genetic metabolic disorders, today reported business highlights and financial results for the second quarter ended June 30, 2015.

"In the first half of 2015, we continued to drive rapid and meaningful progress across our development programs, as well as selecting our fourth molecule for development, AG-881, and advancing it into two Phase 1 studies," said David Schenkein, M.D., chief executive officer of Agios. "Additionally, we recently initiated DRIVE PK, a Phase 2 study of AG-348 in PK deficiency patients, and are on track to initiate two global, registration-enabling Phase 3 studies of AG-221 and AG-120 in patients with acute myeloid leukemia in the next six to 12 months. These efforts bring us closer to our goal of being a late-stage biopharmaceutical company capable of changing the treatment paradigm for people with cancer and rare genetic disorders."

SECOND QUARTER 2015 FINANCIAL RESULTS

Cash, cash equivalents and marketable securities as of June 30, 2015 were $434.0 million, compared to $467.4 million as of December 31, 2014. The decrease was driven by cash expenditures for operating activities of approximately $64.9 million, which was offset by cash received from Celgene of approximately $43.3 million during the six months ended June 30, 2015 related to our collaboration agreements.

Collaboration revenue was $13.2 million for the second quarter of 2015, compared to $8.4 million for the comparable period in 2014. The increase reflects revenues recognized under the company's collaboration agreements with Celgene, including $8.8 million related to the delivery of the U.S. and ex-U.S. licenses for AG-881.

Research and development (R&D) expense was $36.4 million, including $4.6 million of stock- based compensation expense in the second quarter of 2015, compared to $22.6 million, including $1.4 million in stock-based compensation expense for the comparable period in 2014. 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.

General and administrative (G&A) expense was $8.9 million, including $3.6 million of stock-based compensation expense, in the second quarter of 2015, compared to $4.2 million, including $1.0 million of stock-based compensation expense, for the comparable period in 2014. The increase in G&A expense was largely due to increased headcount and other professional expenses to support growing operations.

Net loss for the second quarter of 2015 was $31.9 million, compared to net loss of $18.3 million for the comparable period in 2014.

ADJUSTED FINANCIAL GUIDANCE FOR THE FULL YEAR 2015

Today Agios raised its previous year end cash guidance and now expects to end 2015 with more than $350.0 million of cash, cash equivalents and marketable securities. The anticipated year end 2015 cash position does not include any additional program-specific milestone payments. Agios expects that its cash, cash equivalents and marketable securities would be sufficient to fund its operating expenses and capital expenditure requirements until late 2017.
