MacroGenics Provides Update on Corporate Progress and 2017 Financial Results

ROCKVILLE, Md., Feb. 27, 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 provided a corporate progress update and reported financial results for the year ended December 31, 2017.

"We have had multiple advances in our portfolio of product candidates recently," said Scott Koenig, M.D., Ph.D., President and CEO of MacroGenics. "In addition to margetuximab passing an interim futility analysis for the SOPHIA Phase 3 metastatic breast cancer study, a combination of margetuximab with an anti-PD-1 agent has shown encouraging activity in the treatment of gastric cancer patients in a Phase 2 study. Furthermore, we continue to enroll relapsed/refractory acute myeloid leukemia (AML) patients in the flotetuzumab dose expansion study following the promising results that were presented at recent medical conferences. As we continue to advance these and our other candidates, we look forward to presenting additional data in 2018 and defining future development strategies across our portfolio."

Key Pipeline Updates

Margetuximab. Recent highlights related to the Company's Fc-optimized monoclonal antibody that targets the human epidermal growth factor receptor 2, or HER2, include:

  • Phase 3 Metastatic Breast Cancer Study. The pivotal SOPHIA study is evaluating the efficacy of margetuximab plus chemotherapy compared to trastuzumab plus chemotherapy in approximately 530 relapsed/refractory HER2-positive metastatic breast cancer patients. In January 2018, the Company announced the completion of a pre-planned interim futility analysis with the recommendation of an independent data safety monitoring committee to continue SOPHIA as planned without modification. This analysis was based on a pre-specified assessment of progression-free survival as determined by independent central review. The Company also announced that the U.S. FDA had 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. MacroGenics remains on track to complete enrollment of the study by the end of 2018.
  • Phase 2 Gastric Cancer Study. In January 2018, MacroGenics presented interim clinical data from a Phase 2 study of margetuximab plus an anti-PD-1 agent in patients with gastric and gastroesophageal junction (GEJ) cancer. These results included encouraging tolerability, a 32% objective response rate and median progression-free survival of 5.5 months in a subpopulation of 25 patients with gastric cancer. Based on these results, MacroGenics is expanding the study by enrolling 25 additional gastric cancer patients and will continue to evaluate biomarkers to determine the patients who are most likely to benefit from margetuximab plus anti-PD-1 therapy.

Flotetuzumab. Recent highlights of the Company's bispecific, humanized DART molecule that recognizes both CD123 and CD3, include:

  • Monotherapy Study. Updated data from an ongoing dose expansion study of flotetuzumab in patients with AML and myelodysplastic syndrome (MDS) were presented at the Annual American Society of Hematology (ASH) Meeting in December 2017. Consistent with previously disclosed earlier dose escalation data, flotetuzumab demonstrated acceptable tolerability as well as evidence of anti-leukemic activity. MacroGenics continues to enroll the AML and MDS dose-expansion cohorts and anticipates presenting updated clinical data in 2018. The Company's collaborator, Servier, has development and commercialization rights outside North America, Japan, Korea and India for flotetuzumab, also known as S80880.
  • Planned Combination Study with anti-PD-1. At the Annual ASH Meeting in December 2017, MacroGenics presented data supporting the rationale for using checkpoint blockade as an approach to potentially enhance the anti-leukemic activity of flotetuzumab. MacroGenics intends to initiate a combination study with MGA012, an anti-PD-1 monoclonal antibody (mAb), by mid-2018.

Other Pipeline Assets Update

Additional programs that the Company is advancing include the following:

PD-1-Directed Immuno-Oncology Franchise. MacroGenics is advancing multiple PD-1-directed programs to enable both a broad set of combination opportunities across the Company's portfolio and provide further differentiation from existing PD-1-based treatment options. These programs include:

  • MGA012. MGA012 is a humanized, proprietary anti-PD-1 monoclonal antibody being developed for use as monotherapy as well as in combination with other potential cancer therapeutics. MGA012 was licensed to Incyte Corporation in 2017 under a global collaboration and license agreement. Patients are being enrolled across multiple dose expansion cohorts in a Phase 1 study.
  • MGD013. MacroGenics designed a DART molecule, MGD013, to provide 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. MGD013 is currently being evaluated in a Phase 1 dose escalation study. MacroGenics expects to establish the dose and schedule for MGD013 administration as well as initiate dose expansion cohorts in 2018.
  • MGD019. This DART molecule is designed to provide co-blockade of both PD-1 and CTLA-4 on T cells. The Company is completing Investigational New Drug (IND)-enabling studies and anticipates submitting the IND application for MGD019 in 2018.

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. These molecules include:

  • Enoblituzumab: The Company continues to recruit patients with various solid tumors in an ongoing study of this Fc-optimized monoclonal antibody that targets B7-H3, in combination with an anti-PD-1 mAb. The Company expects to present clinical data from this study in 2018.
  • MGD009: This DART molecule targeting B7-H3 and CD3 is being evaluated in a Phase 1 study across multiple solid tumor types. The Company expects to establish the dose and schedule for MGD009 administration as well as initiate monotherapy dose expansion cohorts in 2018. In addition, a combination study of MGD009 and MGA012 was recently initiated.
  • MGC018: The Company is completing IND-enabling activities to support submission of an IND application for this anti-B7-H3 antibody drug conjugate (ADC) in 2018.

Additional DART Clinical Programs. Additional DART molecules in Phase 1 clinical development being led by MacroGenics include the following:

  • MGD007.  The Company is completing a monotherapy study of MGD007, a DART molecule that recognizes gpA33 and CD3, and anticipates commencing a combination study with MGA012 in 2018.
  • MGD014. MacroGenics' first DART molecule designed to target an infectious agent, MGD014 recognizes the envelope protein of HIV-infected cells (Env) and the T cells' CD3 component, to redirect the immune system's T cells to kill HIV-infected cells. The Company expects to commence the Phase 1 study in 2018.

Corporate Update

  • Incyte Collaboration. In October 2017, MacroGenics announced that it had entered into a global collaboration and license agreement with Incyte. The Company received an upfront payment of $150 million upon closing in December 2017 and is eligible to receive milestones and royalties on any future sales of MGA012. MacroGenics retains the right to develop its own pipeline assets in combination with MGA012, with Incyte commercializing MGA012 and MacroGenics commercializing its combinatorial asset(s), if any such potential combinations are approved. In addition, MacroGenics retains the right to manufacture a portion of both companies' global clinical and commercial supply needs of MGA012.
  • Roche Collaboration. In January 2018, MacroGenics announced that it had entered into a research collaboration and license agreement with F. Hoffmann-La Roche Ltd and Hoffmann-La Roche Inc. ("Roche") to jointly discover and develop novel bispecific molecules to undisclosed targets. MacroGenics received an upfront payment of $10 million from Roche in January 2018 and is eligible to receive potential milestone payments and royalties on future sales.
  • GMP Manufacturing Suite Build-out: The Company began the expansion of its manufacturing capacity in early 2017 by commencing the build-out of a GMP suite in its headquarters building in Rockville, Maryland to support larger-scale clinical and commercial manufacturing. MacroGenics expects this manufacturing suite to be fully operational in 2018.
  • Dr. Jay Siegel Added to Board. In November 2017, MacroGenics announced the appointment of Jay Siegel, M.D., former Chief Biotechnology Officer and Head of Scientific Strategy and Policy at Johnson & Johnson, to its Board of Directors.
