First Dosing of Pfizer DART Candidate in Phase 1 Study Triggers Milestone Payment to MacroGenics

ROCKVILLE, Md., May 10, 2016 (GLOBE NEWSWIRE) -- MacroGenics, Inc. (Nasdaq: MGNX) today announced that its collaboration partner, Pfizer Inc. (NYSE: PFE), has advanced a bispecific antibody therapeutic candidate generated by MacroGenics' Dual-Affinity Re-Targeting, or DART®, platform. Pfizer recently dosed a first patient in the Phase 1 clinical study of PF-06671008, which targets P-cadherin and CD3. Increased levels of the protein P-cadherin have been reported in various tumors, including breast, ovarian, endometrial, colorectal and pancreatic cancers, and is correlated with poor survival of patients. The commencement of the Phase 1 study triggers a $2 million milestone payment to MacroGenics under the companies' October 2010 agreement.

PF-06671008 is the first partner-developed DART molecule to enter clinical development and represents the sixth DART molecule in clinical testing. At present, MacroGenics’ clinical pipeline includes multiple DART candidates for the treatment of cancer and one DART candidate for the treatment of autoimmune disorders.

Background on DART Platform

MacroGenics' DART platform enables the targeting of multiple antigens or cells by using a single molecule with an antibody-like structure. DART molecules can be configured for the potential treatment of cancer, autoimmune disorders and infectious diseases. These DART molecules can be tailored for either short or prolonged pharmacokinetics and have demonstrated good stability and attractive manufacturability. Six DART molecules, including programs being developed by MacroGenics and its collaborators, are currently being evaluated in clinical studies.
