Imvotamab (IGM-2323) is a CD20xCD3 bispecific IGM antibody with dual action mechanism. Imvotamab is used to induce physiological T cell activation to prevent over-stimulation and subsequent down-regulation of immune function. Imvotamab is currently being developed for the treatment of B-cell malignant tumors, multiple myeloma (MM) and non-Hodgkin's lymphoma (NHL).

Histone H3 is one of the DNA-binding proteins found in the chromatin of all eukaryotic cells. H3 along with four core histone proteins binds to DNA forming the structure of the nucleosome. Histones play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. Histone H3 has three main variants, H3.1 and H3.2, which are deposited in chromatin only during DNA replication and H3.3, which is replication independent and is found primarily in the regions of active transcription and heterochromatin. Post translationally, histones are modified in a variety of ways to either directly change the chromatin structure or allow for the binding of specific transcription factors. The N-terminal tail of histone H3 protrudes from the globular nucleosome core and can undergo several different types of post-translational modification that influence cellular processes. These modifications include the covalent attachment of methyl or acetyl groups to lysine and arginine amino acids and the phosphorylation of serine or threonine. Histone modifications are one form of epigenetic information that relate closely to gene regulation. Aberrant histone methylation caused by alteration in chromatin-modifying enzymes has long been implicated in cancers. Recently, recurrent histone mutations have been identified in multiple cancers and have been shown to impede histone methylation. All identified histone mutations (including H3K4M, H3K9M, H3K27M, H3K36M, and H3G34V/R/W) result in amino acid substitution at/near a lysine residue that is a target of methylation.

Suvratoxumab (MEDI4893) is a long-acting, high-affinity humanized anti-α-toxin monoclonal antibody (IgG1κ type). Suvratoxumab potently neutralizes α-toxin, a key S. aureus virulence factor. Suvratoxumab improves survival and reduces lung injury in an immunocompromised mice model of pneumonia. Suvratoxumab also enhances the antibacterial activity of Vancomycin (HY-B0671) or Linezolid (HY-10394).
