Itepekimab (REGN-3500) is an IgG4 monoclonal antibody against IL-33. Itepekimab reduced airway inflammation and related tissue damage in preliminary clinical studies. Itepekimab has potential effects in asthma, chronic obstructive pulmonary disease (COPD), and atopic dermatitis (AD).

Tozorakimab (MEDI-3506) is a human immunoglobulin G1 monoclonal antibody targeting interleukin-33. Tozorakimab reduces inflammation and epithelial dysfunction. Tozorakimab can be used to research chronic obstructive pulmonary disease.

Etokimab (Antibody ANB 020) is a humanized monoclonal antibody that targets IL-33. Etokimab can be used for the research of atopic dermatitis.

Talacotuzumab (JNJ 56022473; CSL 362) is an IgG1-type fully humanized, CD123-neutralizing monoclonal antibody containing a modified Fc structure. Talacotuzumab has KDs of 0.43 nM, 188 nM, 46 nM, 16.8 nM for CD123, CD32b/c, CD16-158F, CD16-158V, respectively. Talacotuzumab inhibits IL-3 binding to CD123, antagonizing IL-3 signaling in target cells. Talacotuzumab has mutated the Fc region to increase affinity for CD16 (FcγRIIIa), thereby enhancing antibody-dependent cell-mediated cytotoxicity (ADCC). Talacotuzumab is highly effective in vivo reducing leukemic cell growth in acute myeloid leukemia (AML) xenograft mouse models.

Depemokimab (GSK-3511294) is a long-acting anti-IL-15 monoclonal antibody. Depemokimab can be used for research of asthma.
