Agios Pharmaceuticals to Present Clinical and Preclinical Data at the 2014 American Society of Hematology Annual Meeting

New Data from Ongoing Phase 1 AG-221 Trial Accepted for Oral Presentation

Poster Presentation to Reveal First Clinical Data for AG-348, a Potential Treatment for Pyruvate Kinase Deficiency

Company to Host Investor Lunch and Webcast on Monday, December 8, 2014

CAMBRIDGE, Mass., Nov. 6, 2014 (GLOBE NEWSWIRE) -- Agios Pharmaceuticals, Inc. (Nasdaq:AGIO) today announced that new data from the Phase 1 clinical trial for AG-221, a first-in-class IDH2 mutant inhibitor, will be presented at the 2014 American Society of Hematology (ASH) Annual Meeting and Exposition in San Francisco, December 6-9, 2014. In total, six abstracts led by Agios describing new clinical and preclinical data from the company's cancer metabolism and rare genetic disorders of metabolism programs have been accepted for presentation at ASH. Agios' cancer metabolism medicines are being developed in collaboration with Celgene.

"Agios has a strong presence at ASH this year, and we are very encouraged by the data we will have the opportunity to present across our programs," said David Schenkein, M.D., chief executive officer of Agios. "Data included in the abstract from our ongoing Phase 1 study of AG-221 in patients with advanced IDH2 mutant-positive hematologic malignancies show further evidence of safety and durable clinical activity among patients who desperately need new and better treatment options. In addition, the emerging data from the Phase 1 healthy volunteer studies for AG-348 allow us to advance into patients in early 2015 and lend support to the hypothesis that targeting the underlying defect of PK deficiency could potentially improve clinical outcomes."

Highlights of selected data presentations include:

AG-221: a first-in-class, oral, selective, potent inhibitor of the mutated IDH2 protein

  • Data included in the AG-221 abstract released today provide new safety and efficacy data as of July 24, 2014 from the Phase 1 study of AG-221 in advanced hematologic malignancies. The oral presentation on December 7, 2014 will be updated with longer follow-up data and additional patients since the data in the submission of today's abstract.

AG-348: a novel, first-in-class, oral activator of pyruvate kinase-R (PKR) for the treatment of pyruvate kinase (PK) deficiency, a cause of hemolytic anemia

  • The presentation for AG-348 will include the first data showing safety, pharmacokinetic data and effects on pharmacodynamics markers from the single ascending dose (SAD) and multiple ascending dose escalation (MAD) studies in healthy volunteers.

The accepted abstracts are listed below and are now available online on the ASH conference website: www.ash.confex.com/ash/2014/webprogram/start.html.

Investor Lunch and Webcast Information

Agios will host an investor lunch on Monday, December 8, 2014 beginning at 12:00 p.m. PST (3:00 p.m. EST) in San Francisco to review data presented at ASH, including new data from the ongoing Phase 1 study of AG-221 and data from AG-348's Phase 1 healthy volunteer studies. The event will be webcast live and can be accessed under "Events & Presentations" in the Investors and Media section of the company's website at www.agios.com.

About AG-221 and IDH2

IDH1 and IDH2 are metabolic enzymes that are mutated in a wide range of hematologic and solid tumor malignancies, including AML. Normally, IDH enzymes help to break down nutrients and generate energy for cells. When mutated, IDH creates a molecule that alters the cells' genetic programming, and instead of maturing, the cells remain primitive and proliferate quickly. Agios believes that inhibition of these mutated proteins may lead to clinical benefit for the subset of cancer patients whose tumors carry them. AG-221 was developed by Agios as a selective, potent inhibitor of the mutated IDH2 protein. While most cancer treatments attempt to destroy the cancerous cells, AG-221 uniquely attacks its target – mutated IDH2 – and aids the maturation of the cells into functioning blood cells. AG-221 has received orphan drug designation for AML and fast track designation for patients with IDH2-mutant AML.

About Agios/Celgene Collaboration

AG-221 is a part of Agios' global strategic collaboration with Celgene Corporation, an integrated global biopharmaceutical company. In June 2014, Celgene exercised its exclusive option to license AG-221 and gained worldwide development and commercialization rights for AG-221. Agios continues to conduct early clinical development activities within the AG-221 development program. The companies are also collaborating on the development of AG-120, which is being studied in two Phase 1 trials in patients whose hematologic malignancies and solid tumors carry an IDH1 mutation. Agios retains U.S. development and commercialization rights for AG-120, and Celgene has an exclusive option to the ex-U.S. rights.

About AG-348 and Pyruvate Kinase (PK) Deficiency, a Rare, Inherited Hemolytic Anemia

Pyruvate kinase deficiency, a rare, inherited hemolytic anemia affecting children and adults, is caused by mutations that affect the activity of the metabolic enzyme pyruvate kinase-R (PKR), the form of pyruvate kinase that is present in red blood cells. The current standard of care for PK deficiency is supportive, including blood transfusions, splenectomy, chelation therapy to address iron overload and/or interventions for other treatment- and disease-related morbidities. Currently, there is no approved therapy to treat the underlying cause of PK deficiency. AG-348 is a first-in-class orally available, potent, selective small molecule activator of PKR, which, when mutated, leads to PK deficiency. AG-348 was discovered in the laboratory of Agios, and the company retains worldwide development and commercialization rights.
