Press Release

ROCKVILLE, Md., July 30, 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 June 30, 2020.

“We are excited about the momentum we have built to date in 2020. We have presented promising initial clinical data at ASCO from the MGD013 and MGC018 programs. We have defined a potential registration path for flotetuzumab and we have received FDA clearance to initiate clinical testing of our novel antibody-drug conjugate targeting ADAM9 being co-developed with ImmunoGen. Furthermore, we were able to extend our cash runway into 2023,” said Scott Koenig, M.D., Ph.D., President and CEO of MacroGenics. “In the coming months, we anticipate presentation of clinical data from other investigational product candidates in our pipeline, including MGD019, a PD-1 × CTLA-4 DART® molecule, and retifanlimab, an anti-PD-1 antibody. Additionally, the PDUFA goal date for the margetuximab BLA is in December.”

Key Highlights from Investigational Product Candidates

• MGC018 (B7-H3 antibody-drug conjugate): At the American Society of Clinical Oncology (ASCO) Virtual Annual Meeting in May, data were presented from the ongoing Phase 1/2 dose escalation study of MGC018 that suggested manageable safety and preliminary activity in patients with metastatic castration-resistant prostate cancer (mCRPC). The Company expects to commence the enrollment of an expansion cohort of patients with mCRPC as part of the Phase 1/2 study in the third quarter of 2020.
   
• Flotetuzumab (bispecific CD123 × CD3 DART molecule): In May, MacroGenics announced that the trial of flotetuzumab designed to support registration in the U.S. will be a single arm study in up to 200 patients with AML whose disease is refractory to induction treatment (primary induction failure) or has relapsed after a remission of less than six months (early relapse). The trial will be conducted as an expansion of the ongoing Phase 1/2 study. The primary endpoint is a response rate comprised of complete remission (CR) and CR with partial hematological recovery (CRh). The Company plans to submit updated data for presentation at a scientific conference in the fourth quarter of 2020.
   
• Margetuximab (Fc-engineered, anti-HER2 mAb): The Food and Drug Administration (FDA) notified MacroGenics in May that it no longer plans to hold an Oncologic Drugs Advisory Committee (ODAC) meeting to discuss the Biologics License Application (BLA) for margetuximab in combination with chemotherapy as a treatment for patients with metastatic HER2-positive breast cancer. The Prescription Drug User Fee Act (PDUFA) target action date is December 18, 2020.
  
  In July, The Lancet Oncology published results from a Phase 2 study of margetuximab and pembrolizumab in second-line patients with advanced HER2-positive gastric or gastroesophageal junction cancer. These data formed the basis for conducting the ongoing Phase 2/3 MAHOGANY study of margetuximab plus checkpoint blockade in front-line patients.

• MGD013 (bispecific PD-1 × LAG-3 DART molecule): At the ASCO Virtual Annual Meeting, results were presented from dose escalation and select expansion cohorts from the ongoing Phase 1 study of MGD013 in advanced solid tumors as well as the combination of MGD013 and margetuximab in a cohort of patients with advanced HER2-positive tumors. MacroGenics is expanding enrollment of the combination cohort.
   
• MGD019 (bispecific PD-1 × CTLA-4 DART molecule): Data from the Phase 1 dose escalation study of MGD019 are scheduled to be presented during an oral session at the European Society for Medical Oncology (ESMO) Virtual Congress 2020 to be held September 19-21.
   
• IMGC936 (ADAM9 antibody-drug conjugate): In July, MacroGenics received FDA clearance of the Investigational New Drug (IND) application for IMGC936 that is being advanced under a co-development agreement with ImmunoGen, Inc. ADAM9 is a cell surface protein over-expressed in several solid tumor types. ImmunoGen expects to initiate a Phase 1 dose escalation study in patients with select advanced solid tumors in the fourth quarter of 2020.
   
• Enoblituzumab (Fc-engineered, anti-B7-H3 mAb): MacroGenics expects to initiate a Phase 2 study of enoblituzumab in combination with retifanlimab as a chemo-free regimen in front-line patients with advanced head and neck cancer in the first quarter of 2021.
   
• Retifanlimab (anti-PD-1 mAb also known as MGA012 or INCMGA0012): Data from POD1UM-201, the ongoing study of retifanlimab monotherapy in patients with Merkel cell carcinoma, are scheduled to be presented during a poster session at the ESMO Virtual Congress 2020. In addition, data from POD1UM-202, the fully-enrolled, potentially registration-enabling monotherapy study in patients with squamous cell carcinoma of the anal canal, are expected to be presented at a medical congress in the second half of 2020. Retifanlimab was invented by MacroGenics and licensed to Incyte.

During the quarter ended June 30, 2020, $96.5 million in net proceeds were received from the sale of 4,060,482 shares of the Company’s common stock pursuant to its at-the-market (ATM) offering. Subsequent to June 30, 2020, an additional $21.3 million net proceeds were received from the sale of 726,380 shares pursuant to the Company’s ATM offering and $12.0 million was received from Boehringer Ingelheim GmbH under a 2010 license and collaboration agreement.
   
• Revenue: Total revenue, consisting primarily of revenue from collaborative agreements, was $20.3 million for the quarter ended June 30, 2020, compared to $10.6 million for the quarter ended June 30, 2019. This increase was primarily due to $12.0 million recognized from the agreement with Boehringer Ingelheim.
   
• R&D Expenses: Research and development expenses were $57.4 million for the quarter ended June 30, 2020, compared to $51.4 million for the quarter ended June 30, 2019. This increase was primarily due to an increase in development and clinical trial costs for multiple programs.
   
• G&A Expenses: General and administrative expenses were $10.2 million for the quarter ended June 30, 2020, compared to $12.1 million for the quarter ended June 30, 2019. This decrease is primarily due to a decrease in consulting costs, with a smaller decrease in travel-related costs due to COVID-19.
   
• Net Loss: Net loss was $46.9 million for the quarter ended June 30, 2020, compared to net loss of $31.8 million for the quarter ended June 30, 2019.
