Narsoplimab (OMS 721) is a high-affinity fully human immunoglobulin gamma 4 (IgG4) monoclonal antibody that binds MASP-2 and blocks lectin pathway activation. Narsoplimab can be used in research of hematopoietic stem-cell transplantation and SARS-CoV-2.

Ontamalimab (SHP647) is a fully-human IgG2 monoclonal antibody targeting mucosal addressin cell adhesion molecule-1 (MAdCAM-1). Ontamalimab can be used for the research of Crohn's disease.

Simtuzumab (AB 0024; GS 6624) is a monoclonal antibody directed against Lysyl oxidase like-2 (LOXL2). Simtuzumab can be used for the research of primary sclerosing cholangitis (PSC).

Ladiratuzumab (hLIV22) is an anti-LIV-1/ZIP6 humanized monoclonal antibody. Ladiratuzumab, conjugated with the microtubule disrupting agent, MMAE (HY-15162) to compose SGN-LIV1A, an antibody-drug conjugate (ADC). Ladiratuzumab can be used for research of breast cancer.

Opicinumab (BIIB033) is a monoclonal antibody against LINGO-1 and has potential application in acute optic neuritis and relapse multiple sclerosis.

Polzastobart (JTX-8064) is a humanized IgG4 monoclonal antagonist antibody that selectively binds LILRB2 and prevents it from binding its ligands, classical and non-classical MHC I molecules. Polzastobart enhances pro-inflammatory cytokine production in macrophages by blocking the ability of LILRB2 to bind HLA-A/B and/or HLA-G, a marker of immunotolerance on cancer cells. Polzastobart is a macrophage immune checkpoint inhibitor.

Miptenalimab (BI-754111) is an anti-human LAG-3 antibody (KD: 88.6 nM for h LAG-3). Miptenalimab blocks the interaction of LAG-3 with its ligand MHC-II.

Relatlimab (BMS-986016) is a human monoclonal antibody anti-LAG-3 antibody generated by immunization of transgenic mice bearing human immunoglobulin miniloci with recombinant LAG-3 protein. Relatlimab blocks LAG-3/MHC II interaction with an IC50 value of 0.67 nM and LAG-3/FGL1 interaction with an IC50 value of 0.019 nM. Relatlimab can be used in research of cancer.

Encelimab is an anti-LAG3 antibody. Encelimab blocks the interaction between LAG-3 and MHC II, and enhances T-cell activation. Encelimab alone or in combination with an anti-PD-1 antibody reduces tumor size in a lymphoma mice model (A20 cell xenograft).

Ieramilimab (LAG525; IMP701) is a humanized IgG4 monoclonal antibody that binds to LAG-3, resulting in inhibition of LAG-3 interaction with MHC-II molecules.

Favezelimab (MK-4280) is a humanized anti-LAG-3 monoclonal antibody that blocks the interaction between LAG-3 and its ligand MHC class II. Favezelimab has the potential for colorectal cancer (CRC) research combined with the PD-L1 inhibitor Pembrolizumab (HY-P9902).

Fianlimab (REGN3767) is a human monoclonal antibody that targets the immune checkpoint receptor LAG-3 on T cells and has anti-tumour activity.
