"During the third quarter, MacroGenics made tremendous progress in advancing its portfolio of immuno-oncology product candidates towards multiple near-term data read-outs," said Scott Koenig, M.D., Ph.D., President and CEO of MacroGenics. "Given the Company’s substantial pipeline progress over the past several months, we believe that the next twelve months are poised to be transformative for MacroGenics, during which we expect to continue to advance our core mission of developing breakthrough biologics that may become life-changing medicines for patients."

Key Pipeline Updates
Margetuximab. Recent highlights related to the Company’s Fc-optimized monoclonal antibody (mAb) that targets the human epidermal growth factor receptor 2, or HER2, include:
• Fully Enrolled Phase 3 Metastatic Breast Cancer Study. The Company has completed enrollment of 530 relapsed/refractory HER2-positive metastatic breast cancer patients in its pivotal SOPHIA study. MacroGenics anticipates disclosure of topline PFS data in the first quarter of 2019. In anticipation of a potential future product launch, MacroGenics is progressing its U.S. commercial planning and actively exploring ex-U.S. development and commercialization partnership opportunities.
• Phase 2 Gastric Cancer Study Demonstrated Antitumor Activity. At the 2018 European Society of Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress in October, MacroGenics presented updated interim clinical data from a Phase 2 study of margetuximab plus an anti-PD-1 agent in patients with HER2-positive gastroesophageal adenocarcinoma. This chemotherapy-free combination, designed to coordinately engage innate and adaptive immunity, demonstrated antitumor activity in patients with advanced gastric cancer. The Company recently completed enrollment of 25 additional gastric cancer patients and expects to present data from this ongoing portion of the study in the first quarter of 2019.

PD-1 Franchise. MacroGenics is advancing multiple PD-1-directed programs to provide further differentiation from existing PD-1-based treatment options and enable a broad set of combination opportunities across the Company’s portfolio. Recent program highlights include:

Exhibit 99.1
• MGA012 Achieves Development Milestones. This anti-PD-1 mAb, also known as INCMGA0012, was licensed to Incyte Corporation in 2017 under a global collaboration and license agreement. MacroGenics retains the rights to develop MGA012 in combination with its pipeline assets. MGA012 met certain clinical proof-of-concept criteria, triggering a total of $15 million in milestones from Incyte, $10 million of which has been recognized in the third quarter and $5 million of which is expected to be recognized in the fourth quarter. Incyte plans to present updated data from the cohort expansion portion of the Phase 1 study of MGA012 in a poster session at the upcoming Society for Immunotherapy for Cancer (SITC) (Free SITC Whitepaper) Annual Meeting. Incyte has announced its intention to pursue monotherapy development of MGA012 in MSI-high endometrial cancer, Merkel cell carcinoma and anal cancer through registration-directed studies with initial data anticipated in 2020. In addition, across both Incyte and MacroGenics, multiple studies have been initiated which will feature various combination regimens with MGA012.
• MGD013 Dose Expansion Initiated. This first-in-class DART molecule provides co-blockade of two immune checkpoint molecules expressed on T cells, PD-1 and LAG-3, for the potential treatment of a range of solid tumors and hematological malignancies. MacroGenics recently established the dose and schedule for MGD013 administration and has initiated dose expansion in up to nine tumor types in a Phase 1 study.
• MGD019 IND Cleared. This DART molecule is designed to provide co-blockade of both PD-1 and CTLA-4, two immune checkpoint inhibitors, on T cells. MacroGenics’ Investigational New Drug (IND) application for MGD019 was cleared by the FDA and the Company is currently engaged in Phase 1 study startup.
B7-H3 Franchise. MacroGenics is developing a portfolio of therapeutics that target B7-H3, a member of the B7 family of molecules involved in immune regulation. The Company is advancing multiple programs that target B7-H3 through complementary mechanisms of action that take advantage of this antigen’s broad expression across multiple solid tumor types. Recent program highlights include:
• Enoblituzumab Oral Presentation at SITC (Free SITC Whitepaper): Clinical data from MacroGenics’ study of this Fc-optimized mAb that targets B7-H3 combined with an anti-PD-1 mAb was selected for oral presentation at the upcoming SITC (Free SITC Whitepaper) Annual Meeting. Like the combination of margetuximab and anti-PD-1, enoblituzumab and anti-PD-1 is designed to leverage Fc-optimization and checkpoint blockade to coordinately engage innate and adaptive immunity, the two major components of the immune response. As an update of the recently released abstract, the combination of enoblituzumab and anti-PD-1 demonstrated antitumor activity in checkpoint inhibitor-naïve patients who had squamous cell carcinoma of the head and neck (SCCHN) and in checkpoint inhibitor-naïve patients with non-small cell lung cancer (NSCLC) with tumor PD-L1 expression of <1%. In these two cohorts, objective responses occurred in 6/18 (33%) response-evaluable SCCHN patients and in 5/14 (36%) response-evaluable NSCLC patients. Additional details will be provided at SITC (Free SITC Whitepaper).
• Orlotamab Studies Ongoing: This DART molecule targeting B7-H3 and CD3 is being evaluated in a Phase 1 monotherapy study in multiple tumor types. In addition, a combination study of orlotamab and MGA012 is ongoing.
• MGC018 Phase 1 Startup Initiated: MacroGenics’ IND submission for this anti-B7-H3 antibody-drug conjugate (ADC) was cleared by the FDA and the Company is initiating a Phase 1 study. This first-in-man study is designed to study MGC018 both as monotherapy and in combination with MGA012 in patients with solid tumors.
Flotetuzumab. Recent highlights of the Company’s bispecific, humanized DART molecule that recognizes both CD123 and CD3, include:
• Oral Presentations at ASH (Free ASH Whitepaper). MacroGenics plans to present both updated clinical data as well as gene signature data from its completed acute myeloid leukemia (AML) dose expansion cohort in two oral presentations at the American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting next month. The Company’s collaborator, Servier, has development and commercialization rights outside North America, Japan, Korea and India for flotetuzumab, also known as S80880.

Exhibit 99.1
• Combination Study with MGA012 Planned. MacroGenics has previously presented data supporting the rationale for using checkpoint blockade as an approach to potentially enhance the anti-leukemic activity of flotetuzumab and plans to commence a combination study with MGA012.

Third Quarter 2018 Financial Results
• Cash Position: Cash, cash equivalents and marketable securities as of September 30, 2018, were $260.1 million, compared to $305.1 million as of December 31, 2017.
• Revenue: Total revenue, consisting primarily of revenue from collaborative agreements, was $20.8 million for the quarter ended September 30, 2018, compared to $1.7 million for the quarter ended September 30, 2017. This increase was primarily due to revenue recognized under the Incyte MGA012 collaboration. Revenue from collaborative agreements includes the recognition of deferred revenue from payments received in previous periods as well as payments received during the year.
• R&D Expenses: Research and development expenses were $46.2 million for the quarter ended September 30, 2018, compared to $41.0 million for the quarter ended September 30, 2017. This increase was primarily due to the initiation of combination studies of MGA012, continued enrollment in multiple ongoing studies, increased development/manufacturing costs related to MGA012, which were partially reimbursed by Incyte, and increased headcount to support expanded manufacturing and development activities.
• G&A Expenses: General and administrative expenses were $9.6 million for the quarter ended September 30, 2018, compared to $8.4 million for the quarter ended September 30, 2017. This increase was primarily due to increased patent-related expenses and consulting and other costs incurred related to the implementation of the Company’s new enterprise resource planning (ERP) system.
• Net Loss: Net loss was $34.0 million for the quarter ended September 30, 2018, compared to net loss of $47.0 million for the quarter ended September 30, 2017.
• Shares Outstanding: Shares outstanding as of September 30, 2018 were 42,248,075.
