-- Six Immuno-Oncology Clinical Programs Projected by End of 2015 --

-- Cash Runway Extends Into 2017 --

ROCKVILLE, Md., March 20, 2014 (GLOBE NEWSWIRE) -- MacroGenics, Inc. (Nasdaq:MGNX), a clinical-stage biopharmaceutical company focused on discovering and developing innovative monoclonal antibody-based therapeutics for the treatment of cancer and autoimmune diseases, today provided a corporate progress update and reported financial results for the year ended December 31, 2013.

"2013 was a transformative year for MacroGenics, with significant clinical, operational and financial accomplishments to advance our mission of harnessing the power of the immune system to fight cancer and autoimmune diseases," said Scott Koenig, M.D., Ph.D., President and CEO of MacroGenics. "With the completion of our initial public offering, the receipt of substantial milestone payments under our corporate partnerships and our recent follow-on financing, we are in a strong financial position to advance our proprietary pipeline of product candidates."

"Looking forward, in 2014, we will continue to invest in our pipeline through the significant expansion of our clinical development programs. We plan to initiate a Phase 3 study of margetuximab in patients with gastroesophageal cancer in the second half of the year and are advancing a Phase 2a study of margetuximab in patients with metastatic breast cancer. By the end of 2014, we expect to complete the first three dose expansion cohorts of a Phase 1 clinical trial of MGA271. In addition, 2014 should be an important year for our Dual-Affinity Re-Targeting (DART®), or bi-specific, antibody platform as we intend to begin the clinical evaluation of two DART candidates, including MGD006 for acute myeloid leukemia and MGD007 for colorectal cancer," concluded Dr. Koenig.

Development Pipeline Update

Margetuximab is an Fc-optimized monoclonal antibody that targets HER2-expressing tumors, including breast, gastroesophageal and other cancers. Highlights include:

MGA271 is an Fc-optimized monoclonal antibody that targets B7-H3, which is over-expressed on a wide variety of solid tumor types and is a member of the B7 family of molecules involved in immune regulation. Recent highlights include:

MGD006 is a humanized DART-based molecule that recognizes both CD123 and CD3. CD123, the Interleukin-3 receptor alpha chain, is expressed on leukemia and leukemic stem cells. The primary mechanism of action of MGD006 is its ability to redirect T cells, via their CD3 component, to kill CD123-expressing cells. Recent highlights include:

Proprietary Pre-Clinical Pipeline Update

MacroGenics continues to advance its immuno-oncology portfolio of other proprietary, pre-clinical product candidates and expects to have a total of six clinical programs by the end of 2015. These include MGD007, an oncology DART that recognizes both gpA33 and CD3 and for which the Company intends to initiate clinical testing in the second half of 2014. MacroGenics also intends to initiate clinical testing of two additional oncology DART-based product candidates in 2015. The Company's autoimmune portfolio, which includes MGD010, a DART that targets both CD32B and CD79B, is also progressing in pre-clinical development.
