Item 7.01. Regulation FD Disclosure.

On January 23, 2018, the Company issued a press release announcing completion of a pre-planned interim futility analysis of the Phase 3 SOPHIA trial. SOPHIA is a randomized, controlled, multi-center study that compares margetuximab plus chemotherapy to trastuzumab plus chemotherapy in subjects with metastatic breast cancer. Based on the results from the futility analysis, an independent data safety monitoring committee has recommended that the SOPHIA trial continue as planned. In addition, the Company also announced in the same press release that the U.S. FDA has granted Fast Track designation of margetuximab for treatment of patients with metastatic or locally advanced HER-2 positive breast cancer who have previously been treated with anti-HER2-targeted therapy. A copy of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K and incorporated by reference herein.

MacroGenics Announces Continuation of SOPHIA Study of Margetuximab Based on Completion of Interim Futility Analysis
FDA grants Fast Track designation to margetuximab for treatment of metastatic breast cancer
Rockville, MD, Jan. 23, 2018 (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, today announced completion of a pre-planned interim futility analysis of the Phase 3 SOPHIA trial. This randomized, multi-center clinical study compares margetuximab plus chemotherapy to trastuzumab plus chemotherapy in subjects with metastatic breast cancer. Based on results from the futility analysis, an independent data safety monitoring committee (DSMC) has recommended that the SOPHIA study continue as planned without modification. This analysis was based on a pre-specified assessment of progression-free survival (PFS) as determined by independent central review. The futility analysis did not allow for early stopping due to efficacy.
MacroGenics also announced today that the U.S. FDA has granted Fast Track designation for the investigation of margetuximab for treatment of patients with metastatic or locally advanced HER2 positive breast cancer who have previously been treated with anti-HER2-targeted therapy.  Fast Track designation is designed to facilitate the development and expedite the review of new therapies for serious conditions and unmet medical needs. With Fast Track designation, early and frequent communications between the FDA and the sponsor are encouraged to help enable rapid development of the candidate molecule.
"We are encouraged with the DSMC's determination that there were no safety concerns and that the analysis of PFS data support continuation of the Phase 3 SOPHIA trial. Recruitment of patients into the SOPHIA study is progressing well. We remain on track to complete enrollment by the end of 2018 and we look forward to sharing top-line results after the trial has read out in 2019," commented Scott Koenig, M.D., Ph.D., President and Chief Executive Officer of MacroGenics. "Also, we are very pleased to receive Fast Track designation for margetuximab, as this may potentially expedite future regulatory interactions on this product candidate. Furthermore, the gastric cancer data recently presented at ASCO GI for margetuximab in combination with anti-PD-1 may provide additional opportunities to address unmet medical needs in other HER2+ indications."
About the SOPHIA Study
MacroGenics continues to enroll patients in the pivotal Phase 3 SOPHIA clinical study of margetuximab at approximately 200 trial sites across North America, Europe and Asia. The 530-patient study is designed to evaluate the efficacy of margetuximab plus chemotherapy compared to that of trastuzumab plus chemotherapy in relapsed/refractory HER2-positive metastatic breast cancer patients. This registration study has sequential primary endpoints, which include PFS and overall survival. For additional information on the ongoing SOPHIA trial, visit www.clinicaltrials.gov .

About Margetuximab
Margetuximab is an Fc-optimized monoclonal antibody that targets the human epidermal growth factor receptor 2, or HER2, oncoprotein. HER2 is expressed by tumor cells in breast, gastric, and other forms of solid tumor cancers, making it a key marker for biologic therapy. In addition to being studied in metastatic breast cancer, margetuximab is also being studied in combination with an anti-PD-1 agent in a Phase 1b/2 clinical trial in gastric cancer, for which data was recently presented at the recent ASCO Gastrointestinal Symposium.
