简介

Receptor for the invariable Fc fragment of immunoglobulin gamma (IgG). Optimally activated upon binding of clustered antigen-IgG complexes displayed on cell surfaces, triggers lysis of antibody-coated cells, a process known as antibody-dependent cellular cytotoxicity (ADCC). Does not bind free monomeric IgG, thus avoiding inappropriate effector cell activation in the absence of antigenic trigger (PubMed:24412922, PubMed:25786175, PubMed:21768335, PubMed:22023369, PubMed:8609432, PubMed:9242542, PubMed:25816339, PubMed:11711607, PubMed:28652325). Mediates IgG effector functions on natural killer (NK) cells. Binds antigen-IgG complexes generated upon infection and triggers NK cell-dependent cytokine production and degranulation to limit viral load and propagation. Involved in the generation of memory-like adaptive NK cells capable to produce high amounts of IFNG and to efficiently eliminate virus-infected cells via ADCC (PubMed:25786175, PubMed:24412922). Regulates NK cell survival and proliferation, in particular by preventing NK cell progenitor apoptosis (PubMed:9916693, PubMed:29967280). Fc-binding subunit that associates with CD247 and/or FCER1G adapters to form functional signaling complexes. Following the engagement of antigen-IgG complexes, triggers phosphorylation of immunoreceptor tyrosine-based activation motif (ITAM)-containing adapters with subsequent activation of phosphatidylinositol 3-kinase signaling and sustained elevation of intracellular calcium that ultimately drive NK cell activation. The ITAM-dependent signaling coupled to receptor phosphorylation by PKC mediates robust intracellular calcium flux that leads to production of pro-inflammatory cytokines, whereas in the absence of receptor phosphorylation it mainly activates phosphatidylinositol 3-kinase signaling leading to cell degranulation (PubMed:2532305, PubMed:1825220, PubMed:23024279). Costimulates NK cells and trigger lysis of target cells independently of IgG binding (PubMed:23006327, PubMed:10318937). Mediates the antitumor activities of therapeutic antibodies. Upon ligation on monocytes triggers TNFA-dependent ADCC of IgG-coated tumor cells (PubMed:27670158). Mediates enhanced ADCC in response to afucosylated IgGs (PubMed:34485821). (Microbial infection) Involved in Dengue virus pathogenesis via antibody-dependent enhancement (ADE) mechanism. Secondary infection with Dengue virus triggers elevated levels of afucosylated non-neutralizing IgG1s with reactivity to viral envelope/E protein. Viral antigen-IgG1 complexes bind with high affinity to FCGR3A, facilitating virus entry in myeloid cells and subsequent viral replication.

HM2023-05: GTB-3650 (Anti-CD16/IL-15/Anti-CD33) Tri-Specific Killer Engager (TriKE®) for the Treatment of High Risk Myelodysplastic Syndromes (MDS) and Refractory/Relapsed Acute Myeloid Leukemia (AML)

This is a Phase I dose finding study of GTB-3650 (anti-CD16/IL-15/anti-CD33) Tri-Specific Killer Engager (TriKE®) for the treatment of select CD33-expressing refractory/relapsed myeloid malignancies in adults ≥ 18 years of age who are not a candidate for potentially curative therapy, including hematopoietic stem cell transplantation, and are refractory to, intolerant of, or ineligible for therapy options that are known to provide clinical benefit. The hypothesis is GTB-3650 TriKE will induce natural killer (NK) cell function by targeting malignant cells, as well as, CD33+ myeloid derived suppressor cells (MDSC) which contribute to a tumor induced immunosuppression. Because CD16 is the most potent activating receptor on NK cells, this single agent may induce a targeted antiCD33+ tumor response

Identification of novel anti-CD16a antibody clones for the development of effective natural killer cell engagers

Article

作者: Corper, Adam ; Li, Lin ; Begum, Hydari ; Chang, Alex ; Woods, Catherine ; Fan, Xiaomin ; Farokhi, Elinaz ; Liao, Bill ; Challa, Dilip ; Tumanut, Christine

Natural killer (NK) cells are key players in human innate immunity. Cell engager antibody formats that recruit and activate NK cells more effectively have emerged as a promising immunotherapy approach to target cancer cells through more effective antibody-dependent cell-mediated cytotoxicity (ADCC). Monoclonal antibody drugs with ADCC activity have shown clinical benefit and improved outcomes for patients with certain types of cancer. CD16a, a Fc gamma III receptor, is the major component that is responsible for the ADCC activity of NK cells. Screening AvantGen's yeast displayed human antibody libraries led to the isolation of 2 antibody clones, #1A2 and #2-2A2, that selectively recognize both isoforms (F and V) of CD16a on primary NK cells with high affinity, yet minimally (#1A2) or do not (#2-2A2) cross-react with both allelotypes of CD16b (NA1 and NA2) expressed by neutrophils. Epitope mapping studies revealed that they bind to an epitope dependent on residue Y158 of CD16a, since mutation of Y158 to the corresponding CD16b residue H158 completely abolishes binding to CD16a. When formatted as bispecific antibodies targeting CD16a and a tumor-associated antigen (TAA, e.g. CD19), they exhibit specific binding to NK cells and induce potent NK cell activation upon encountering tumor cells, resulting in effective tumor cell killing. Notably, these bispecific antibody engagers stimulate NK cell cytokine release during co-culture with target cells, resulting in target cell cytotoxicity. These anti-CD16a antibody clones are promising candidates for combination with any TAA of interest, offering the potential for novel NK cell engager-based cancer therapeutics that are minimally affected by the high concentrations of human IgG in the circulation.

FCGR3A F158V alleles frequency differs in multiple myeloma patients from healthy population

Article

作者: Jacquard, Carine ; Presumey, Jessy ; Campos-Mora, Mauricio ; Robert, Nicolas ; Multrier, Caroline ; Gao, Fei ; Cartron, Guillaume ; Villalba, Martin ; Coënon, Loïs ; Moreaux, Jérome ; Zemiti, Sara ; Constantinides, Michaël

FCGR3A presents a single nucleotide polymorphism at location 158 (V/F), which affects its binding to the fragment crystallizable (Fc) of antibodies (Abs). FcγRIIIa-158 V allotype has the highest affinity and is associated with a better clinical response to IgG1 monoclonal Abs (mAb) treatment. We compared the allele frequency of FCGR3A-F158V polymorphism in cohorts of patients with B-cell lymphoproliferative disorders, including multiple myeloma (MM), monoclonal gammopathy of undetermined significance (MGUS), non-Hodgkin lymphoma (NHL), and B-cell chronic leukemia (B-CLL). FCGR3A-158F homozygous were enriched and tended to be in MM and MGUS patients, respectively; but neither in B-CLL nor in NHL patients. We identified a significantly lower concentration of CD8 T-cells and resting memory CD4 T-cells in MM patients bone marrow with the F/F genotype, associated with an increase in the macrophage percentage. In contrast, natural killer cells increased in V/V homozygous patients. This suggests a deregulation of the immune microenvironment in FCGR3A-F/F homozygous patients. However, we did not observe difference in response following treatment combining chemotherapy associated or not with daratumumab, an IgG1 mAb direct against CD38. Our findings suggest that FCGR3A F158V polymorphism can regulate the immune environment and affect the development of tumor plasma cells.

Afucosylated anti-EBOV antibody MIL77-3 engages sGP to elicit NK cytotoxicity

Article

作者: Zhang, Min ; Wu, Xiaonan ; Wang, Jing ; Xiao, He ; Zhang, Yuting ; Li, Xinying ; Qiao, Chunxia ; Zheng, Hang ; Wang, Mianjing ; Wang, Youchun ; Chen, Guojiang ; Wu, Haiyan ; Luo, Longlong ; Wang, Yi ; Zheng, Yuanqiang ; Feng, Jiannan ; Feng, Junjuan ; Huang, Weijin

ABSTRACT MIL77-3 is one component of antibody cocktail that is produced in our lab and represents an effective regimen for animals suffering from Zaire Ebolavirus (EBOV) infection. MIL77-3 is engineered to increase its affinity for the FcγRIIIa (CD16a) by deleting the fucose in the framework region. The potential effects of this modification on host immune responses, however, remain largely unknown. Herein, we demonstrated that MIL77-3 recognized secreted glycoproptein (sGP), produced by EBOV, and formed the immunocomplex to potently augment antibody-dependent cytotoxicity of human peripheral blood-derived natural killer cells (pNKs), including CD56 dim and CD56 bright subpopulations, in contrast to the counterparts (Mab114, rEBOV548, fucosylated MIL77-3). Intriguingly, this effect was not observed when NK92-CD16a cell line was utilized and restored by the addition of beads-coupled or membrane-anchored sGP in combination with MIL77-3. Furthermore, sGP bound to unrecognized receptors on T cells contaminated in pNKs rather than NK92-CD16a cells. Administration of beads-coupled sGP/MIL77-3 complex in mice elicited NK activation. Overall, this work reveals an immune-stimulating function of sGP/MIL77-3 complex by triggering cytotoxic activity of NK cells, highlighting the necessity to evaluate the potential impact of MIL77-3 on host immune reaction in clinical trials. IMPORTANCE Zaire Ebolavirus (EBOV) is highly lethal and causes sporadic outbreaks. The passive administration of monoclonal antibodies (mAbs) represents a promising treatment regimen against EBOV. Mounting evidence has shown that the efficacy of a subset of therapeutic mAbs in vivo is intimately associated with its capacity to trigger NK activity, supporting glycomodification of Fc region of anti-EBOV mAbs as a putative strategy to enhance Fc-mediated immune effector function as well as protection in vivo . Our work here uncovers the potential harmful influence of this modification on host immune responses, especially for mAbs with cross-reactivity to secreted glycoproptein (sGP) (e.g., MIL77-3), and highlights it is necessary to evaluate the NK-stimulating activity of a fucosylated mAb engaged with sGP when a new candidate is developed.

MacroGenics Enters Into Agreement With TerSera Therapeutics for the Sale of MARGENZA®

ROCKVILLE, MD & DEERFIELD, IL, USA I October 22, 2024 I MacroGenics, Inc. (NASDAQ: MGNX), a biopharmaceutical company focused on discovering, developing, manufacturing and commercializing innovative antibody-based therapeutics for the treatment of cancer, and TerSera Therapeutics LLC, a privately-held biopharmaceutical company with a focus in oncology and non-opioid pain management, announced today that they have entered into an agreement in which TerSera will acquire global rights to MARGENZA® (margetuximab-cmkb). MARGENZA was approved by the U.S. Food and Drug Administration (FDA) in December 2020 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 approval was based on results from the pivotal Phase 3 head-to-head clinical trial (SOPHIA) evaluating the safety and efficacy of MARGENZA vs. Herceptin® (trastuzumab), both combined with chemotherapy. Pursuant to the terms of the agreement, TerSera will pay MacroGenics $40 million at closing. MacroGenics may receive additional sales milestone payments of up to an aggregate of $35 million. The transaction is expected to close in the fourth quarter of 2024, subject to customary closing conditions. “This transaction will enable us to focus our efforts on advancing our pipeline of novel and differentiated oncology product candidates,” said Scott Koenig, M.D., Ph.D., President and Chief Executive Officer of MacroGenics. “We believe TerSera’s established and complementary U.S. commercial infrastructure has the potential to broaden patient access to MARGENZA.” “MARGENZA is an important treatment option for patients with metastatic HER2+ breast cancer,” said Edward Donovan, Chief Executive Officer of TerSera. “We are very excited to add MARGENZA to our existing oncology portfolio, deepening our commitment to the treatment of patients with breast cancer.” IMPORTANT SAFETY INFORMATION BOXED WARNING: LEFT VENTRICULAR DYSFUNCTION AND EMBRYO-FETAL TOXICITY WARNINGS & PRECAUTIONS: Left Ventricular Dysfunction Embryo-Fetal Toxicity Infusion-Related Reactions (IRRs) MOST COMMON ADVERSE REACTIONS: The most common adverse drug reactions (>10%) with MARGENZA in combination with chemotherapy are fatigue/asthenia (57%), nausea (33%), diarrhea (25%), vomiting (21%), constipation (19%), headache (19%), pyrexia (19%), alopecia (18%), abdominal pain (17%), peripheral neuropathy (16%), arthralgia/myalgia (14%), cough (14%), decreased appetite (14%), dyspnea (13%), infusion-related reactions (13%), palmar-plantar erythrodysesthesia (13%), and extremity pain (11%). You may report side effects to the FDA at (800) FDA-1088 or www.fda.gov/medwatch or to MacroGenics at (844)-MED-MGNX (844-633-6469). INDICATION MARGENZA is a HER2/neu receptor antagonist indicated, 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. Please see full Prescribing Information , including Boxed Warning. About HER2-positive Breast Cancer Human epidermal growth factor receptor 2 (HER2) is a protein found on the surface of some cancer cells that promotes growth and is associated with aggressive disease and poor prognosis. Approximately 15-20% of breast cancer cases are HER2-positive. Monoclonal antibodies targeting HER2 have greatly improved outcomes; however, a significant number of patients progress to later lines of therapy. Effective treatments for metastatic HER2-positive breast cancer continue to remain an unmet need. About MARGENZA MARGENZA (margetuximab-cmkb) is an Fc-engineered, monoclonal antibody that targets the HER2 oncoprotein. HER2 is expressed by tumor cells in breast, gastroesophageal and other solid tumors. Similar to trastuzumab, margetuximab-cmkb inhibits tumor cell proliferation, reduces shedding of the HER2 extracellular domain and mediates antibody-dependent cellular cytotoxicity (ADCC). However, through MacroGenics’ Fc Optimization technology, margetuximab-cmkb has been engineered to enhance the engagement of the immune system. In vitro, the modified Fc region of margetuximab-cmkb increases binding to the activating Fc receptor FCGR3A (CD16A) and decreases binding to inhibitor Fc receptor FCGR2B (CD32B). These changes lead to greater in vitro ADCC and NK cell activation. The clinical significance of in vitro data is unknown. About MacroGenics, Inc. MacroGenics is a biopharmaceutical company focused on discovering, developing, manufacturing and commercializing innovative monoclonal antibody-based therapeutics for the treatment of cancer. The Company generates its pipeline of product candidates primarily from its proprietary suite of next-generation antibody-based technology platforms, which have applicability across broad therapeutic domains.
