ROCKVILLE, Md., Nov. 02, 2021 (GLOBE NEWSWIRE) -- MacroGenics, Inc. (NASDAQ: MGNX), a biopharmaceutical company focused on developing and commercializing innovative monoclonal antibody-based therapeutics for the treatment of cancer, today provided an update on its recent corporate progress and reported financial results for the quarter ended September 30, 2021.

“In September, we were pleased to present encouraging preliminary results from our ongoing Phase 1 cohort expansion study of MGC018 at the European Society for Medical Oncology (ESMO) Annual Meeting. We look forward to providing additional clinical data updates on this study next year as well as sharing our future development plans for this molecule in the first quarter of next year, after continued engagement with Key Opinion Leaders and regulatory agencies,” said Scott Koenig, M.D., Ph.D., President and CEO of MacroGenics. “Beyond MGC018, we continue to advance our growing pipeline of investigational product candidates for the potential treatment of cancer. Finally, the recent FDA approval to manufacture MARGENZA drug substance at our GMP manufacturing facility is an important achievement for the Company.”

Updates on Proprietary Programs

The recent progress and key events related to MacroGenics’ investigational product candidates in clinical development and its approved product, MARGENZA, are highlighted below:

  • MGC018 is an antibody-drug conjugate (ADC) that targets B7-H3. At ESMO, MacroGenics presented encouraging preliminary clinical results from the ongoing Phase 1 study of MGC018 in patients with solid tumors. The Phase 1 study cohort expansions are ongoing for metastatic castrate-resistant prostate cancer (mCRPC), non-small cell lung cancer (NSCLC), melanoma, squamous cell carcinoma of the head and neck (SCCHN) and triple negative breast cancer (TNBC). The Company expects to present additional data from the ongoing Phase 1 study of MGC018 in the first half of next year. In addition, MacroGenics intends to provide details regarding further development plans in mCRPC in the first quarter of 2022. The Company also intends to initiate a study combining MGC018 with one of its proprietary checkpoint inhibitor molecules in the first half of next year.
  • Enoblituzumab?is an Fc?engineered, monoclonal antibody that targets B7?H3. MacroGenics?continues to recruit patients into its Phase 2 study of enoblituzumab in a chemotherapy-free regimen in combination with retifanlimab in front-line patients with SCCHN who are PD-L1 positive and with tebotelimab in SCCHN patients who are PD-L1 negative. In September, I-Mab Biopharma announced that an IND to initiate a Phase 2 trial of enoblituzumab in combination with pembrolizumab in patients with select solid tumors was accepted in China, triggering a net $4.5 million milestone payment to MacroGenics. I-Mab has development and commercial rights to enoblituzumab in Greater China.
  • Bispecific CD123 × CD3 DART molecules:
    • Flotetuzumab?is a bispecific CD123 × CD3 DART molecule being evaluated in patients with refractory acute myeloid leukemia (AML).?MacroGenics is conducting a single-arm clinical study to evaluate flotetuzumab in up to 200 patients with refractory AML, with complete remission (CR) and CR with partial hematological recovery (CRh) as the composite primary endpoint. The Company anticipates providing further updates on the clinical development of flotetuzumab in 2022.
    • MGD024 is a next-generation, bispecific CD123 × CD3 DART molecule designed to minimize cytokine-release syndrome, while maintaining anti-tumor cytolytic activity, and has an Fc domain to permit intermittent dosing through a longer half-life. MacroGenics submitted an IND application for MGD024 to the FDA in October. The Company intends to present preclinical MGD024 data at the American Society of Hematology (ASH) Annual Meeting in December.
  • Tebotelimab?is a bispecific, tetravalent DART molecule targeting PD-1 and LAG-3. MacroGenics is evaluating the molecule in patients as monotherapy as well as in combination with other agents. The Company’s partner for this molecule in Greater China, Zai Lab, expanded its Phase 1b/2 study of tebotelimab in combination with the PARP inhibitor niraparib into new indications, including gastric cancer, TNBC and biliary tract cancer. In addition, Zai Lab enrolled the first patient in an endometrial cancer cohort in October 2021.
  • MGD019 is a bispecific, tetravalent DART molecule targeting PD-1 and CTLA-4. The Company is conducting a Phase 1 dose expansion study in cohorts of patients with microsatellite stable colorectal cancer (MSS CRC), checkpoint-naïve NSCLC, mCRPC and melanoma. The Company anticipates sharing data from its ongoing Phase 1 dose expansion study next year.
  • IMGC936 is an ADC that targets ADAM9, a cell surface protein over-expressed in several solid tumor types, and is being developed jointly under a 50/50 collaboration with ImmunoGen, Inc. Under the collaboration, ImmunoGen is leading clinical development of IMGC936 in a Phase 1 clinical trial evaluating safety and pharmacokinetics in multiple solid tumors and has indicated they anticipate disclosing initial data in 2022.
  • Margetuximab?is an Fc-engineered, monoclonal antibody (mAb) that targets the HER2 oncoprotein, which is expressed by certain breast, gastroesophageal and other solid tumor cells.
    • MARGENZA Commercial Launch.?In March 2021, MacroGenics and its commercial partner, EVERSANA, launched MARGENZA for the treatment of adult patients with metastatic HER2-positive breast cancer, in combination with chemotherapy, who have received two or more prior anti-HER2 regimens, at least one of which was for metastatic disease. As previously reported, the median overall survival (OS) in the intent-to-treat population was not statistically different between the two arms. A prespecified, non-alpha allocating, exploratory analysis of OS by CD16A genotype in the SOPHIA trial showed a numerical OS advantage in favor of margetuximab in F homozygous patients and a numerical OS advantage in favor of trastuzumab in V homozygous patients. Finally, MacroGenics recently received U.S. FDA approval to manufacture MARGENZA drug substance at its GMP manufacturing facility in Rockville, MD.
    • MAHOGANY Study. At ESMO, MacroGenics presented results from Cohort A Part 1 of the Phase 2/3 MAHOGANY study of margetuximab in combination with retifanlimab, an anti-PD-1 molecule the Company licensed to Incyte Corporation, in patients with advanced gastric and gastroesophageal junction cancer.?Although the number of confirmed responses by independent review (twenty one of 40 (53%) patients) exceeded the prespecified futility boundary for this chemotherapy-free regimen, MacroGenics has decided to discontinue enrollment of Cohort A based on a number of factors, including the prioritization of its other product candidates given the competition in this indication, and the accelerated approval of combination therapy with pembrolizumab. MacroGenics’ partner for margetuximab in Greater China, Zai Lab, continues to enroll patients in Cohort B.
    • Zai Lab’s Bridging Study. In October 2021, Zai Lab announced that the bridging study of margetuximab plus chemotherapy in advanced, previously treated HER2-positive breast cancer met its primary endpoint with acceptable safety and tolerability. The study showed that efficacy of the combination in Chinese patients was consistent with that seen in the global population in MacroGenics’ SOPHIA Phase 3 trial. Zai Lab has indicated that it anticipates submitting a BLA in China for pretreated metastatic HER2-positive breast cancer by approximately year-end 2021.

Updates on Partnered Program

  • Retifanlimab is an investigational anti-PD-1 antibody that MacroGenics licensed to Incyte. Incyte will present clinical results in poster presentations from both a Phase 2 study of retifanlimab in patients with advanced or metastatic Merkel cell carcinoma and a tumor specific expansion cohort study in patients with recurrent MSI-H or deficient mismatch repair (dMMR) recurrent endometrial cancer at the 2021 Society for Immunotherapy of Cancer (or SITC) Virtual Meeting taking place November 10 - 14, 2021.

Third Quarter 2021 Financial Results
