MacroGenics Provides Update on Corporate Progress and Third Quarter 2020 Financial ResultsConference call scheduled for today at 4:30 p.m. ET.

ROCKVILLE, Md., Nov. 04, 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 provided an update on its corporate progress and reported financial results for the quarter ended September 30, 2020.

“MacroGenics continued the advancement of its portfolio of multiple clinical molecules during the third quarter of 2020, with three investigational programs currently in pivotal studies: margetuximab, flotetuzumab and retifanlimab. The PDUFA action date for margetuximab in breast cancer is December 18. Just prior, we look forward to our next presentation of flotetuzumab clinical data at ASH in December, following the publication of data in three separate journals this year highlighting the medical and scientific interest in this DART® molecule,” said Scott Koenig, M.D., Ph.D., President and CEO of MacroGenics. "At ESMO in September, we and our partner, Incyte, presented clinical data on MGD019 and retifanlimab, respectively. And on the heels of MGC018 data presented at ASCO, we recently commenced the enrollment of patients with mCRPC, TNBC and NSCLC. More near-term, we look forward to providing an update on tebotelimab plus margetuximab in HER2-positive patients at the upcoming SITC Annual Meeting this month. Finally, we look forward to updating you on continued progress through the rest of 2020 and into 2021.”

Key Highlights from Investigational Product Candidates in Pivotal Studies:

  • Margetuximab (Fc-engineered, anti-HER2 mAb): A Biologics License Application (BLA) for margetuximab, in combination with chemotherapy as a treatment for patients with metastatic HER2-positive breast cancer, is being reviewed by the U.S. Food and Drug Administration (FDA). The Prescription Drug User Fee Act (PDUFA) target action date is December 18, 2020. Based on the current accrual rate of overall survival (OS) events in the Phase 3 SOPHIA study, MacroGenics now anticipates accrual of the 385th OS event, which triggers the final OS analysis, in the second half of 2021.

    Enrollment of the global Phase 2/3 MAHOGANY study of margetuximab plus checkpoint blockade, with or without chemotherapy, as a potential first-line treatment for patients in front-line gastric and gastroesophageal junction cancer is ongoing. MacroGenics’ partner in Greater China, Zai Lab, recently announced dosing of the first patient in that region. MacroGenics anticipates providing a clinical update on Module A of the study in the first half of 2021.
     
  • Flotetuzumab (bispecific CD123 × CD3 DART molecule): During the third quarter, two manuscripts were published in Blood and Blood Advances, two publications of the American Society of Hematology (ASH). The first publication reported on clinical results as of November 2019, while the most recent publication reported on the potential role of flotetuzumab in the immunotherapy of TP53-positive acute myeloid leukemia (AML). In addition, six flotetuzumab and AML abstracts were accepted for presentation at the upcoming ASH Annual Meeting.

    MacroGenics continues to enroll the single-arm, registrational study to evaluate flotetuzumab in up to 200 AML patients with primary induction failure or early relapse (PIF/ER) AML, with complete remission (CR) and CR with partial hematological recovery (CRh) as the primary endpoint.
     
  • Retifanlimab (anti-PD-1 mAb previously known as MGA012 or INCMGA0012): At the European Society for Medical Oncology (ESMO) Virtual Congress 2020 in September, data from potentially registration-enabling monotherapy studies in patients with squamous cell carcinoma of the anal canal and Merkel cell carcinoma were presented. Also in September, a $15 million milestone payment to MacroGenics was triggered under the Company’s exclusive global collaboration and license agreement with Incyte Corporation. This milestone was triggered by Incyte’s initiation of the Phase 3 clinical trial evaluating the efficacy and safety of retifanlimab with platinum-based chemotherapy in patients with metastatic squamous and non-squamous non-small cell lung cancer (NSCLC).

Key Highlights from Other Investigational Product Candidates:

  • MGC018 (B7-H3 antibody-drug conjugate): Encouraged by the MGC018 interim clinical dose escalation data presented at the American Society of Clinical Oncology (ASCO) meeting in May, the Company recently commenced the enrollment of patients with metastatic castration-resistant prostate cancer (mCRPC), triple negative breast cancer (TNBC) and non-small cell lung cancer (NSCLC) in the dose expansion portion of the Phase 1 clinical study. The Company expects to provide an update on this study in the first half of 2021.
  • Enoblituzumab (Fc-engineered, anti-B7-H3 mAb): In the first quarter of 2021, MacroGenics expects to initiate a Phase 2 study of enoblituzumab in a chemo-free regimen in combination with either retifanlimab in front-line patients with squamous cell carcinoma of the head and neck (SCCHN) who are PD-L1 positive or with tebotelimab in SCCHN patients who are PD-L1 negative.
  • Tebotelimab (also known as MGD013, a bispecific PD-1 × LAG-3 DART molecule): The Company will present updated data via poster presentation from the ongoing Phase 1 dose expansion study of tebotelimab in combination with margetuximab in a cohort of patients with advanced HER2-positive tumors at the upcoming Society for Immunotherapy of Cancer (SITC) Annual Meeting.
  • MGD019 (bispecific PD-1 × CTLA-4 DART molecule): In September, data from the Phase 1 dose escalation study of MGD019 was presented during an oral session at the ESMO Virtual Congress 2020. Based on the results presented, the Company has expanded the study initially in patients with microsatellite stable colorectal cancer (MSS CRC) and checkpoint-naïve NSCLC at the recommended Phase 2 dose of 6.0 mg/kg.
  • IMGC936 (ADAM9 antibody-drug conjugate): IMGC936 is an ADC that targets ADAM9, a cell surface protein over-expressed in several solid tumor types. IMGC936 is being advanced under a co-development agreement with ImmunoGen, Inc. Under the 50/50 collaboration, ImmunoGen is leading clinical development and they are currently screening patients for the Phase 1 dose escalation study in patients with select advanced solid tumors.

Third Quarter 2020 Financial Results
