Key Updates on Proprietary Programs
Recent progress and anticipated events in 2021 related to MacroGenics’ approved and investigational product candidates in clinical development, as well as an advanced preclinical program, are highlighted below.
- 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 (margetuximab-cmkb) approval and commercial launch. In
December 2020, the FDA approved MARGENZA in combination with chemotherapy for the treatment of adult patients with metastatic HER2-positive breast cancer who have received two or more prior anti-HER2 regimens, at least one of which was for metastatic disease. The launch, which is being coordinated with MacroGenics’ commercial partner, EVERSANA, is expected in March.
- Phase 2/3 MAHOGANY study in advanced gastric (GC) and gastroesophageal junction (GEJ) cancer. The MAHOGANY clinical program contains two modules designed to evaluate margetuximab as an investigational agent in combination with a checkpoint inhibitor, with or without chemotherapy, as a potential first-line treatment for patients with advanced or metastatic HER2-positive GC/GEJ. Initial safety and efficacy data from among the first 40 patients enrolled in Module A, which is evaluating margetuximab in combination with retifanlimab (an anti-PD-1 therapy), are expected in the first half of 2021. Enrollment in Module B, which is evaluating margetuximab plus MacroGenics’ checkpoint inhibitor molecules in combination with chemotherapy compared to standard of care therapy of trastuzumab with chemotherapy in patients with HER2-positive tumors irrespective of PD-L1 expression, is currently ongoing in coordination with the Company's regional partner in
Greater China, Zai Lab.
- MARGENZA (margetuximab-cmkb) approval and commercial launch. In
- Flotetuzumab is a bispecific CD123 × CD3 DART® molecule being evaluated in patients with primary induction failure (PIF) and early relapsed (less than six months, or ER6) AML. Six clinical and preclinical abstracts related to AML and flotetuzumab were presented at the
American Society of Hematology(ASH) Annual Meeting & Exposition in December 2020. MacroGenicsis conducting a single-arm, registration-enabling clinical study to evaluate flotetuzumab in up to 200 patients with PIF/ER6 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 the second half of 2021, and completing full enrollment of this study in 2022.
- MGC018 is an antibody-drug conjugate that targets B7-H3.
MacroGenicscontinues to enroll 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 mid-2021.
- Enoblituzumab is an Fc‐engineered, anti‐B7‐H3 mAb. In the coming weeks, MacroGenics expects to initiate a Phase 2 study of enoblituzumab in a chemo-free regimen in combination with retifanlimab in front-line patients with squamous cell carcinoma of the head and neck (SCCHN) who are PD-L1 positive and with tebotelimab in SCCHN patients who are PD-L1 negative.
- Tebotelimab is a bispecific, tetravalent DART molecule targeting PD-1 and LAG-3. Tebotelimab is being evaluated in a Phase 1 dose expansion study as monotherapy in several tumor types. An oral presentation of tebotelimab Phase 1 data in patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL) was made at ASH in
December 2020. In addition, data from the combination study of tebotelimab and margetuximab in patients with advanced HER2+ neoplasms were presented at the Society for Immunotherapy of Cancer(SITC) Annual Meeting in November 2020. MacroGenics’ regional partner in Greater China, Zai Lab, is also evaluating tebotelimab in Phase 1 combination studies with niraparib and brivanib for the study of advanced gastric cancer and hepatocellular carcinoma, respectively, as well as a monotherapy study in patients with melanoma. MacroGenicsexpects to provide clinical updates on tebotelimab in 2021, including future development plans.
- MGD019 is a bispecific, tetravalent DART molecule targeting PD-1 and CTLA-4. The Company is enrolling Phase 1 dose expansion cohorts, initially in patients with microsatellite stable colorectal cancer (MSS CRC) and checkpoint-naïve NSCLC at the recommended Phase 2 dose. The Company expects to provide a clinical update on this study in mid-2021.
- IMGC936 is an antibody-drug conjugate 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 the Phase 1 dose escalation study is currently enrolling patients with select advanced solid tumors.
- MGD024 is a next-generation, bispecific CD123 × CD3 DART molecule in preclinical development. The molecule incorporates a CD3 component designed to minimize cytokine-release syndrome, while maintaining anti-tumor cytolytic activity, along with an Fc domain to permit intermittent dosing through a longer half-life. The Company anticipates submitting an Investigational New Drug (IND) application to the FDA by the end of 2021.

IMPORTANT SAFETY INFORMATION - MARGENZA
BOXED WARNING: LEFT VENTRICULAR DYSFUNCTION AND EMBRYO-FETAL TOXICITY
- Left Ventricular Dysfunction: MARGENZA may lead to reductions in left ventricular ejection fraction (LVEF). Evaluate cardiac function prior to and during treatment. Discontinue MARGENZA treatment for a confirmed clinically significant decrease in left ventricular function.
- Embryo-Fetal Toxicity: Exposure to MARGENZA during pregnancy can cause embryo-fetal harm. Advise patients of the risk and need for effective contraception.
WARNINGS & PRECAUTIONS:
Left Ventricular Dysfunction
- Left ventricular cardiac dysfunction can occur with MARGENZA.
- MARGENZA has not been studied in patients with a pretreatment LVEF value of <50%, a prior history of myocardial infarction or unstable angina within 6 months, or congestive heart failure NYHA class II-IV.
- Withhold MARGENZA for ≥16% absolute decrease in LVEF from pre-treatment values or LVEF below institutional limits of normal (or 50% if no limits available) and ≥10% absolute decrease in LVEF from pretreatment values.
- Permanently discontinue MARGENZA if LVEF decline persists greater than 8 weeks, or dosing is interrupted more than 3 times due to LVEF decline.
- Evaluate cardiac function within 4 weeks prior to and every 3 months during and upon completion of treatment. Conduct thorough cardiac assessment, including history, physical examination, and determination of LVEF by echocardiogram or MUGA scan.
- Monitor cardiac function every 4 weeks if MARGENZA is withheld for significant left ventricular cardiac dysfunction.
- Based on findings in animals and mechanism of action, MARGENZA can cause fetal harm when administered to a pregnant woman. Post-marketing studies of other HER-2 directed antibodies during pregnancy resulted in cases of oligohydramnios and oligohydramnios sequence manifesting as pulmonary hypoplasia, skeletal abnormalities, and neonatal death.
- Verify pregnancy status of women of reproductive potential prior to initiation of MARGENZA.
- Advise pregnant women and women of reproductive potential that exposure to MARGENZA during pregnancy or within 4 months prior to conception can result in fetal harm.
