"We have made significant progress in the first half of the year, during which we reported positive results from the Phase 3 SOPHIA study of margetuximab in metastatic HER2-positive breast cancer and enrolled patients into our Phase 1 studies. We believe this progress positions us favorably to achieve several important milestones for our Company during the remainder of 2019," said Scott Koenig, M.D., Ph.D., President and CEO of MacroGenics. "Continuing our focus on execution, in the second half of the year, we are planning to submit the BLA for margetuximab, initiate two registration-directed Phase 2/3 clinical trials, and provide clinical updates for several key programs."

Key Pipeline Updates

Margetuximab. MacroGenics is advancing an investigational, Fc-optimized monoclonal antibody (mAb) that targets human epidermal growth factor receptor 2 (HER2). Highlights include:

•SOPHIA Phase 3 Data Presented at ASCO (Free ASCO Whitepaper); Second Interim OS Data Expected in 4Q2019; Plans to Submit BLA in 4Q2019: At the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting in June 2019, MacroGenics presented data from SOPHIA, the Phase 3 clinical trial of margetuximab in patients with HER2-positive metastatic breast cancer. The trial met the first sequential primary endpoint of prolongation of progression-free survival (PFS) in patients treated with the combination of margetuximab plus chemotherapy compared to trastuzumab plus chemotherapy. The Company expects to present the results from a pre-specified interim OS analysis and submit a Biologics License Application (BLA) to the U.S. FDA in the fourth quarter of 2019.
•MAHOGANY Phase 2/3 Study Advancing in Front-line Gastric Cancer: MacroGenics and Zai Lab, the Company’s partner in Greater China, plan to initiate a Phase 2/3 registration-directed clinical trial of margetuximab in combination with checkpoint inhibitor molecules, including MGA012 (anti-PD-1 mAb) and MGD013 (bispecific PD-1 x LAG-3 DART molecule) in patients with HER2-positive gastric or gastroesophageal junction cancer in the third quarter of 2019.

B7-H3 Franchise. MacroGenics is developing a portfolio of investigational antibody-based therapeutics that target B7-H3 through complementary mechanisms of action taking advantage of this antigen’s broad expression across multiple solid tumor types. Program updates include:

•Advancing Enoblituzumab Study in Head and Neck Cancer: Enoblituzumab is an investigational, Fc-optimized mAb that targets B7-H3. MacroGenics recently met with FDA to discuss its plans regarding a Phase 2/3 registration-directed study of enoblituzumab in combination with MGA012 in patients with squamous cell carcinoma of the head and neck (SCCHN) and anticipates initiating the trial in the fourth quarter of 2019.

Exhibit 99.1
•MGD009 Program Prioritization: MGD009 is an investigational, bispecific DART molecule designed to target B7-H3 expressed on tumor cells and CD3 expressed on normal T cells. The company is prioritizing the development of the combination of MGD009 with MGA012, including plans to add a new dose expansion cohort in patients with melanoma who have previously been treated with a checkpoint inhibitor. MacroGenics has closed patient enrollment in the MGD009 monotherapy study.
•Continued MGC018 Dose Escalation: MGC018 is an investigational, antibody-drug conjugate (ADC) designed to target solid tumors expressing B7-H3 and has advanced through multiple dose levels in the Phase 1 monotherapy dose escalation.

Flotetuzumab. MacroGenics is advancing an investigational, bispecific DART molecule that recognizes both CD123 and CD3. Updates include:

•Completed Enrollment of Monotherapy Study in Acute Myeloid Leukemia (AML); Data Expected 2H2019; Requested End of Phase 1 Meeting with FDA: MacroGenics has completed enrollment of 50 patients at the recommended Phase 2 dose in the Phase 1 monotherapy study, including 30 patients with primary refractory AML. The Company plans to submit updated data from the trial for presentation at the 2019 American Society for Hematology (ASH) (Free ASH Whitepaper) Annual Meeting. MacroGenics plans to meet with the FDA in the third quarter to discuss the flotetuzumab program, and to define a potential registration path for this molecule.
•Plans to Initiate MGA012 Combination Study: MacroGenics plans to initiate a Phase 1 study in combination with MGA012 in relapsed or refractory AML in the third quarter.
•Regaining Full Global Rights: MacroGenics will regain full global rights to develop and commercialize flotetuzumab following Servier’s notification of its intent to terminate the collaboration and license agreement with the Company.
PD-1 Franchise. MacroGenics is advancing multiple investigational PD-1-directed programs to provide differentiation from existing PD-1-based treatment options and enable a broad set of combination opportunities across the Company’s portfolio. Program highlights include:

•MGA012 Registration-directed Studies: MGA012 (INCMGA0012) is an anti-PD-1 mAb exclusively licensed to Incyte Corporation on a worldwide basis. Incyte is pursuing development of MGA012 monotherapy in three ongoing potentially registration-directed trials. Incyte and MacroGenics are each conducting multiple studies of MGA012 in combination with other agents.
•MGD013 Dose Expansion; Data Expected 2H2019: MGD013 is a first-in-class bispecific DART molecule designed to provide co-blockade of PD-1 and LAG-3, two immune checkpoint molecules expressed on T cells. MacroGenics has enrolled approximately 100 patients in the Phase 1 dose expansion study in up to nine tumor types and expects to submit data from this monotherapy trial for presentation at a scientific conference in the second half of 2019.
•MGD019 Dose Escalation: MGD019 is a bispecific DART molecule designed to provide co-blockade of PD-1 and CTLA-4, two immune checkpoint inhibitors expressed on T cells. MGD019 has advanced through multiple dose levels in a Phase 1 dose escalation study.

MGD007. MacroGenics is evaluating an investigational, bispecific DART molecule that recognizes both gpA33 and CD3. MacroGenics completed the enrollment of 26 patients in the Phase 1 expansion cohort of MGD007 in combination with MGA012. The Company expects to provide a clinical update regarding this study in the first quarter of 2020.

Recent Corporate Developments

•Collaboration with I-Mab Biopharma: In July 2019, MacroGenics entered into an exclusive collaboration and license agreement with I-Mab Biopharma (I-Mab) to develop and commercialize enoblituzumab. I-Mab obtains rights in mainland China, Hong Kong, Macau and Taiwan. MacroGenics will receive an upfront payment of $15 million and will also be eligible to receive milestone payments of up to $135 million. In addition, I-Mab will pay tiered royalties ranging from mid-teens to twenty percent based on annual net sales in its territories.
