ROCKVILLE, MD., February 24, 2022 (GLOBE NEWSWIRE) --MacroGenics, Inc. (NASDAQ: MGNX), a biopharmaceutical company focused on developing and commercializing innovative antibody-based therapeutics for the treatment of cancer, today provided an update on its recent corporate progress and reported financial results for the year ended December 31, 2021.
“We are excited about our 2022 plans for our B7-H3-directed programs for the potential treatment of multiple solid tumors. We believe we are well-positioned to be a leader in this promising field and are prioritizing our efforts around B7-H3. First, I am pleased to share that later this quarter, we plan to meet with the U.S. Food and Drug Administration (FDA) to discuss the design of a potential registration-directed study of MGC018 in patients with metastatic castration-resistant prostate cancer (mCRPC). Second, we expect to initiate a study of MGC018 in combination with lorigerlimab, our bispecific DART molecule targeting PD-1 and CTLA-4, in the coming weeks. And third, during the second half of this year, we intend to provide an update from a study of our second B7-H3 targeted molecule, enoblituzumab, being evaluated in combination with two of our checkpoint molecules in front-line squamous cell carcinoma of the head and neck (SCCHN). Beyond these B7-H3 programs, we are advancing several of our other clinical-stage molecules and have a variety of ongoing preclinical activities intended to expand our pipeline of differentiated investigational product candidates for the potential treatment of cancer,” said Scott Koenig, M.D., Ph.D., President and CEO of MacroGenics.
Updates on Proprietary Programs
B7-H3 Programs: MacroGenics is developing two investigational, clinical product candidates that target B7-H3, an antigen with broad expression across multiple solid tumor types and a member of the B7 family of molecules involved in immune regulation. Recent highlights for these two molecules include:
•MGC018 is an antibody-drug conjugate (ADC) that targets B7-H3. MacroGenics presented encouraging preliminary clinical results from an ongoing Phase 1/2 study of MGC018 in patients with solid tumors at the American Society of Clinical Oncology (ASCO) and European Society for Medical Oncology (ESMO) meetings in 2021. The Phase
1/2 study expansion cohorts are fully enrolled for patients with mCRPC (n=40) and smaller cohorts of patients (n=approximately 20 each) with non-small cell lung cancer (NSCLC), melanoma and triple negative breast cancer (TNBC), while the Company continues to recruit patients for the SCCHN cohort. MacroGenics plans to meet with FDA later this quarter to discuss its development strategy in mCRPC. In addition, the Company intends to provide an update on clinical data from the dose expansion cohorts in the second half of 2022 as the data further mature. Finally, beyond monotherapy, the Company expects to initiate a combination study of MGC018 with lorigerlimab across multiple indications in the coming weeks.
•Enoblituzumab is an Fc‐engineered, monoclonal antibody (mAb) that targets B7‐H3. MacroGenics continues to recruit patients into its Phase 2 study of enoblituzumab in combination with retifanlimab, the Company's investigational, anti-PD-1 antibody that was licensed to Incyte, in front-line patients with SCCHN who are PD-L1 positive and with tebotelimab in SCCHN patients who are PD-L1 negative. The Company expects to complete enrollment of the PD-L1 positive patient cohort during the first half of this year and provide an update on this cohort during the second half of the year. I-Mab, MacroGenics’ partner in Greater China, announced in December that the Center for Drug Evaluation (CDE) of China’s National Medical Products Administration (NMPA) approved its Investigational New Drug (IND) submission for the initiation of a Phase 2 trial in China for enoblituzumab in combination with pembrolizumab in patients with solid tumors, including NSCLC, urothelial carcinoma and other selected cancers.
DART Molecules for Immune Checkpoint Blockade: MacroGenics is studying multiple investigational, PD-1-directed programs to provide further differentiation from existing PD-1-based treatment options and enable combination opportunities across the Company’s portfolio. Recent highlights include:
• Lorigerlimab (formerly MGD019) is a bispecific, tetravalent DART molecule targeting PD-1 and CTLA-4. MacroGenics is conducting a Phase 1/2 dose expansion study in cohorts of patients with microsatellite stable colorectal cancer (MSS CRC), mCRPC, melanoma and checkpoint-naïve NSCLC. The Company anticipates sharing data from this ongoing study in the second half of 2022. As described above, MacroGenics expects to initiate a dose escalation study of MGC018 in combination with lorigerlimab in the coming weeks.
•Tebotelimab is a bispecific, tetravalent DART molecule targeting PD-1 and LAG-3. Tebotelimab was evaluated in a Phase 1/2 dose expansion study in several tumor types and is currently being studied in combination with enoblituzumab in SCCHN. The Company expects to provide an update on potential future development plans for tebotelimab in the second half of 2022. MacroGenics' partner in Greater China, Zai lab, recently informed the Company that it has decided to discontinue development of tebotelimab for indications it was enrolling in its territory and is evaluating future development plans in other indications.
Bispecific CD123 × CD3 DART molecule: MacroGenics has prioritized the development of MGD024, its investigational, next-generation CD123 × CD3 DART molecule, and will discontinue the development of flotetuzumab. Recent updates of these DART molecules include:
•MGD024 is a next-generation, humanized CD123 × CD3 DART molecule designed to minimize cytokine-release syndrome, while maintaining anti-tumor cytolytic activity, and permitting intermittent dosing through a longer half-life. In November, MacroGenics announced submission of an IND application for MGD024 to FDA. At the American Society of Hematology (ASH) Annual Meeting in December, MacroGenics presented preclinical data from the combination of MGD024 with standard-of-care agents used to treat CD123-positive hematological malignancies. The Company expects to initiate a Phase 1 dose escalation study of MGD024 in patients with CD123-positive neoplasms, including acute myeloid leukemia (AML), pending IND clearance by FDA.
•Flotetuzumab is the Company’s first-generation, investigational, bispecific CD123 × CD3 DART molecule. An interim efficacy threshold from the single-arm study evaluating flotetuzumab in patients who were refractory to induction therapy was met with manageable safety. However, the Company has recently decided to prioritize the development of MGD024 and discontinue development of flotetuzumab, in view of the Company’s belief that MGD024 may offer certain advantages over flotetuzumab, including easier dose administration and a more facile means to combine with other agents.
Margetuximab is an Fc-engineered mAb that targets the HER2 oncoprotein, which is expressed by certain breast, gastroesophageal and other solid tumor cells. MARGENZA® (margetuximab-cmkb) was launched in March 2021 by MacroGenics and its commercial partner, Eversana Life Science Services, LLC, 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. In January 2022, Zai Lab announced that the China NMPA accepted the New Drug Application (NDA) for margetuximab for the treatment of the same HER2-positive breast cancer indication.
Zai Lab recently informed MacroGenics that they have decided to discontinue enrollment of Module B of the MAHOGANY study in gastric cancer based on their review of both the clinical data and the changing treatment landscape. MacroGenics previously announced in November 2021 that the Company had decided to discontinue enrollment of Module A of the MAHOGANY study.
Selected Partnered Program Updates:
•IMGC936 is an investigational 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.
•Teplizumab is an investigational, anti-CD3 monoclonal antibody acquired from MacroGenics by Provention Bio, Inc. under an asset purchase agreement in 2018 for which MacroGenics is entitled to receive future milestone payments and royalties on net sales. Provention is developing teplizumab for the treatment of type 1 diabetes (T1D). On February 22, 2022, Provention announced that it had resubmitted the Biologics License Application (BLA) for teplizumab for the delay of clinical T1D in at-risk individuals. The BLA resubmission followed Provention’s Type B meeting with FDA earlier in the year.
