Press Release

Rockville, MD, Jan. 09, 2020 (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 its corporate and program priorities for 2020.

“Following the submission in 2019 of our first BLA with the FDA, 2020 has the potential to be a transformative year for MacroGenics. As the product candidates in our deep pipeline enter later-stage clinical trials, we are prioritizing certain programs in order to efficiently utilize our financial, human and intellectual capital on programs with the highest commercial and scientific merit and the potential to achieve regulatory approval," said Scott Koenig, M.D., Ph.D., President and CEO of MacroGenics. “We are excited to advance multiple product candidates in registration-directed studies and believe our program prioritization positions us to capitalize on what we hope will be a pivotal year for the Company.”

Program Prioritization

The Company’s research and development priorities for its investigational molecules in 2020 are highlighted below.

Margetuximab is an Fc-engineered, anti-HER2 monoclonal antibody being evaluated for the treatment of patients with advanced HER2-positive cancers.

• Biologics Licensing Application (BLA) for Metastatic Breast Cancer. Pending acceptance and review of the BLA submitted in December 2019 to the Food and Drug Administration (FDA) based on the Phase 3 SOPHIA study results, the Company anticipates a Prescription Drug User Fee Act (PDUFA) date by the end of 2020. MacroGenics expects a Standard Review process in which the FDA will likely require an Oncologic Drugs Advisory Committee (ODAC) meeting in the second half of 2020.
• Phase 2/3 MAHOGANY Study in Advanced Gastric and Gastroesophageal Junction Cancer. MacroGenics is enrolling patients in this front-line study designed to evaluate the combination of margetuximab with anti-PD-1 based therapies. Initial safety and efficacy data are expected in the second half of 2020 from Module A of this study, which is evaluating a chemotherapy-free regimen. Module A has been designed to support a potential accelerated approval in the U.S. based on evaluation of objective response rate in a single-arm study.

Flotetuzumab is a bispecific CD123 x CD3 DART® molecule being evaluated for the treatment of patients with relapsed or refractory acute myeloid leukemia (AML). MacroGenics intends to define a potential registration path in the U.S. for the treatment of patients with primary induction failure and early relapsed AML in the first half of 2020, pending continued discussions with the FDA.

MGA012 (INCMGA0012) is an anti-PD-1 monoclonal antibody that has been exclusively licensed to Incyte Corporation. There are currently 18 disclosed Phase 1-3 clinical studies evaluating MGA012 in monotherapy and combination regimens across a broad range of tumor types.¹

MGD013 is a first-in-class, bispecific PD-1 x LAG-3 DART molecule being evaluated in a Phase 1 dose expansion study. MacroGenics is selecting indications for further development and expects to submit data from the ongoing study for presentation at a scientific conference in the first half of 2020.

Enoblituzumab is an Fc‐engineered, anti‐B7‐H3 monoclonal antibody. To further inform the development of this molecule, MacroGenics plans to evaluate the activity of both enoblituzumab plus MGA012 and enoblituzumab plus MGD013 as chemotherapy‐free regimens in front‐line patients with recurrent and metastatic squamous cell carcinoma of the head and neck (SCCHN) before proceeding with the full Phase 2/3 study.

MGC018 is an antibody-drug conjugate (ADC) targeting B7-H3 and MGD019 is a bispecific PD-1 x CTLA-4 DART molecule. The Company expects to complete dose escalation for each of these molecules in early 2020 and then initiate a focused dose expansion in select tumor types.

MGD009 is a B7-H3 x CD3 DART molecule and MGD007 is a gpA33 x CD3 DART molecule. In connection with its strategic prioritization, the Company will discontinue development of these programs.

Cash Balance and Cash Runway

The Company’s estimated cash, cash equivalents and marketable securities balance as of December 31, 2019 was approximately $215 million (unaudited), compared to $232.9 million as of December 31, 2018. Through the prioritization of programs and ongoing realignment of its resources, as well as anticipated and potential collaboration payments, MacroGenics is focused on extending its cash runway through 2021. The Company will provide further guidance in connection with reporting 2019 fourth quarter and annual financial results and company progress in late February 2020.

Slide Presentation

A slide presentation describing these corporate priorities, research and development goals and other information will be available on the Investors page on the Company's website at www.macrogenics.com after the market close on Friday, January 10, 2020.
