Agios Pharmaceuticals Reports Fourth Quarter and Full Year 2013 Financial Results

Agios Pharmaceuticals Reports Fourth Quarter and Full Year 2013 Financial Results

March 6, 2014

Pipeline Advancing with Additional Programs Moving into Clinical Development

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Mar. 6, 2014-- Agios Pharmaceuticals, Inc. (NASDAQ: AGIO), a leader in the fields of cancer metabolism and inborn errors of metabolism, today reported business highlights and financial results for the fourth quarter and full year ended December 31, 2013.

"In 2013, we continued to apply our scientific and clinical leadership in the field of cellular metabolism towards our goal of transforming the lives of patients with cancer and inborn errors of metabolism," said David Schenkein, M.D., chief executive officer of Agios. "We successfully filed two investigational new drug applications, or INDs, for novel first-in-class therapeutic candidates and completed IND activities for our third program. In early 2014, we continue to make important progress across our pipeline. Dose escalation in the AG-221 clinical trial continues, and we now plan to present initial clinical data at the 2014 American Association for Cancer Research Annual Meeting in April. We are on track to initiate two clinical trials with AG-120 early this year, and we also plan to initiate clinical trials with AG-348, our first inborn errors of metabolism drug candidate, in mid-2014."

Recent Business Highlights
-- Continued enrollment and dose escalation in the Phase 1 study of AG-221,
an IDH2 mutant inhibitor for the treatment of cancer in patients with an
IDH2 mutation. This Phase 1, multi-center study is evaluating the safety,
pharmacokinetics, pharmacodynamics and clinical activity of AG-221 in
patients with advanced hematologic malignancies that harbor an IDH2
mutation. AG-221 is an orally available, selective, potent inhibitor of
the mutated IDH2 protein, making it a highly targeted therapeutic
candidate for the treatment of patients with cancers with an IDH2
mutation. Agios expects to present initial clinical data from the dose
escalation portion of the ongoing Phase 1 study of AG-221 at the 2014
American Association for Cancer Research Annual Meeting (AACR) in early
April.

-- Completed investigational new drug (IND) filing for AG-120, an IDH1
mutant inhibitor for the treatment of cancer in patients with an IDH1
mutation. The Food and Drug Administration (FDA) recently accepted Agios'
IND for AG-120, and the company remains on track to initiate two Phase 1
clinical trials in early 2014. AG-120 is an orally available, selective,
potent inhibitor of the mutated IDH1 protein, and has been demonstrated
to be a highly targeted therapeutic candidate for the treatment of
patients with cancers that harbor an IDH1 mutation.

-- Exercised the option to U.S. rights to AG-120. Agios elected to exercise
the option to U.S. development and commercial rights for AG-120, in
accordance with the terms of its agreement with Celgene Corporation, with
Celgene retaining its option to ex-U.S. rights.

-- Advanced AG-348, an activator of pyruvate kinase R (PKR) for the
treatment of patients with pyruvate kinase deficiency (PK deficiency),
toward clinical development. Agios has completed IND-enabling studies of
AG-348 and expects to initiate Phase 1 clinical trials for AG-348 in
mid-2014. AG-348 is an orally available, potent, selective small molecule
activator of the PKR enzyme, which, when mutated, leads to PK deficiency,
a form of hereditary hemolytic anemia.

-- Extended cancer metabolism collaboration with Celgene. In December, Agios
announced an extension of one additional year to the period of
exclusivity for its strategic cancer metabolism collaboration with
Celgene. As a result, the exclusive research collaboration between Agios
and Celgene has been extended through April 2015, and Agios will receive
a $20 million extension payment to be paid mid-2014.

Upcoming Milestones
-- Agios expects to present initial clinical data from the dose escalation
portion of the ongoing Phase 1 study of AG-221 at the 2014 American
Association for Cancer Research Annual Meeting (AACR) in early April.
Agios expects to continue enrollment in its Phase 1 study of AG-221 and
initiate expansion cohorts in late 2014.

-- Agios plans to initiate two Phase 1 clinical trials for AG-120 in early
2014 (one in advanced solid tumors and one in hematologic malignancies)
in patients whose cancers carry an IDH1 mutation. These studies will
leverage the clinical trial sites of Agios' Phase 1 study of AG-221.

-- Agios anticipates initiating single and multiple ascending
dose-escalation studies for AG-348 in healthy volunteers in mid-2014.

Fourth Quarter 2013 Financial Results & Financial Guidance
-- Cash Position: Cash, cash equivalents and marketable securities as of
December 31, 2013 were $193.9 million, compared to $128.0 million as of
December 31, 2012. The increase was primarily driven by net proceeds of
$111.0 million from Agios' IPO and $12.8 million from the concurrent
private placement with Celgene, offset by cash used to fund operations.

-- Revenues: Collaboration revenue was $6.7 million for the fourth quarter
of 2013 and $25.5 million for the year ended December 31, 2013,compared
to $6.3 million and $25.1 million in the comparable periods in 2012.
Collaboration revenue is primarily comprised of amortization of deferred
revenue from payments received in previous periods from Agios'
collaboration agreement with Celgene.

-- R&D Expenses: Research and development expenses were $15.3 million in the
fourth quarter of 2013 and $54.5 million for the year ended December 31,
2013, compared to $11.2 million and $41.0 million in the comparable
periods in 2012. The increase in R&D expense was largely due to increased
spending on clinical activities as AG-221 entered Phase 1 development in
September 2013, and as the company prepares to begin clinical development
of AG-120 in early 2014, as well as IND-enabling activities for the
company's AG-348 program.

-- G&A Expenses: General and administrative expenses were $3.7 million in
the fourth quarter of 2013 and $9.9 million in the year ended December
31, 2013, compared to $1.6 million and $7.1 million in the comparable
periods in 2012. The increase in G&A expenses was largely due to
incremental expenses to support public company operations.

-- Net Loss: Net loss was $12.4 million for the fourth quarter of 2013 and
$39.4 million for the year ended December 31, 2013, compared to net loss
of $5.3 million and $20.1 million for the comparable periods in 2012.

-- Financial Guidance: Agios expects that its cash, cash equivalents and
marketable securities will be sufficient to fund its operating expenses
and capital expenditure requirements until late 2016.

"Agios continues to maintain a strong balance sheet, ending 2013 with $193.9 million in cash," said Glenn Goddard, senior vice president of finance at Agios. "We anticipate ending 2014 with more than $130 million in cash. We expect our financial position to provide us with ample funding to execute on our strategic business plan and drive our lead programs to meaningful clinical milestones."
