ROCKVILLE, Md., Aug. 07, 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 an update on its corporate progress and reported financial results for the quarter ended June 30, 2018.

“MacroGenics continues to advance its portfolio of oncology product candidates toward multiple data read-outs,” said Scott Koenig, M.D., Ph.D., President and CEO of MacroGenics. “We expect to complete enrollment of the SOPHIA Phase 3 metastatic breast cancer study of margetuximab in the next few months and be able to disclose top-line results in the first quarter of 2019. Also in early 2019, we expect to provide an update on the combination study of margetuximab with an anti-PD-1 agent in the treatment of gastric cancer patients in a Phase 2 study. In addition, we will provide updates later this year on both the enoblituzumab plus anti-PD-1 combination study, as well as the flotetuzumab monotherapy dose expansion study in patients with relapsed/refractory acute myeloid leukemia (AML). Finally, we recently submitted an investigational new drug (IND) application for our first antibody-drug conjugate — MGC018, an anti-B7-H3 ADC — and anticipate submitting an IND for MGD019 (PD-1 x CTLA-4 DART® molecule) by year-end.”

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:

-- 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. MacroGenics remains on track to complete enrollment of the study in the next few months, with anticipated disclosure of topline PFS data in the first quarter of 2019. -- Phase 2 Gastric Cancer Study. At the 2018 ASCO Annual Meeting in June, 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 that margetuximab plus an anti-PD-1 antibody may have enhanced antitumor activity in patients with advanced gastric cancer. The Company expects to complete enrollment of 25 additional gastric cancer patients in the next few months and present data in the first quarter of 2019.

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

-- Monotherapy Study. MacroGenics has completed the enrollment of its AML dose expansion cohort and plans to present updated clinical data and disclose further development plans in late 2018. The Company’s collaborator, Servier, has development and commercialization rights outside North America, Japan, Korea and India for flotetuzumab, also known as S80880. -- Combination Study with MGA012. MacroGenics has previously presented data supporting the rationale for using checkpoint blockade as an approach to potentially enhance the anti-leukemic activity of flotetuzumab. MacroGenics intends to commence enrollment of a combination study with MGA012, an anti-PD-1 mAb also known as INCMGA0012, later this year.

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. This humanized, proprietary anti-PD-1 mAb is 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. MacroGenics retains the rights to develop MGA012 in combination with its pipeline assets, and has already initiated clinical combination studies with two separate DART molecules. In June 2018, Incyte 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 data anticipated in 2020-2021. -- MGD013.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. MGD013 is currently being evaluated in a Phase 1 study. MacroGenics expects to establish the dose and schedule for MGD013 administration as well as initiate dose expansion cohorts by year end 2018. -- MGD019. This DART molecule is designed to provide co-blockade of both PD-1 and CTLA-4 on T cells. The Company anticipates submitting the IND application for MGD019 by year end 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 completed the recruitment of patients in an ongoing study of this Fc-optimized mAb that targets B7-H3, in combination with an anti-PD-1 mAb and expects to present clinical data from this study as well as disclose further development plans in the fourth quarter of 2018. -- Orlotamab (formerly known as MGD009): This DART molecule targeting B7-H3 and CD3 is being evaluated in a Phase 1 study. The Company recently established the dose and schedule for orlotamab administration and initiated monotherapy dose expansion cohorts in six different tumor types. In addition, a combination study of orlotamab and MGA012 was initiated in the first quarter of 2018 and is ongoing. -- MGC018: The Company has submitted an IND for this anti-B7-H3 ADC and anticipates initiation of a Phase 1 study in the coming months. This first-in-man study is designed to study MGC018 both as monotherapy and in combination with MGA012 in patients with solid tumors.

Second Quarter 2018 Financial Results

-- Cash Position: Cash, cash equivalents and marketable securities as of June 30, 2018, were $300.9 million, compared to $305.1 million as of December 31, 2017. -- Revenue: Total revenue, consisting primarily of revenue from collaborative agreements, was $18.8 million for the quarter ended June 30, 2018, compared to $1.7 million for the quarter ended June 30, 2017. 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 $52.0 million for the quarter ended June 30, 2018, compared to $34.5 million for the quarter ended June 30, 2017. This increase was primarily due to the continued enrollment in the Company’s two margetuximab studies, flotetuzumab study and increased headcount to support expanded manufacturing and development activities. -- G&A Expenses: General and administrative expenses were $11.1 million for the quarter ended June 30, 2018, compared to $8.4 million for the quarter ended June 30, 2017. This increase was primarily due to consulting and other costs incurred related to the implementation of the Company’s new enterprise resource planning (ERP) system and increased patent expenses. -- Net Loss: Net loss was $43.2 million for the quarter ended June 30, 2018, compared to net loss of $40.7 million for the quarter ended June 30, 2017. -- Shares Outstanding: Shares outstanding as of June 30, 2018 were 42,229,011.
