Compound class:
Antibody
Comment: Satralizumab (previously referred to using the replaced INN sapelizumab) is an investigational humanized monoclonal antibody targeting the IL-6 receptor, with immunomodulatory potential. This antibody is an improved version of tocilizumab, with enhanced antigen-neutralizing ability and pharmacokinetics suitable for less frequent administration [2].
Annotated peptide sequences for this antibody are available from its IMGT/mAb-DB record. Peptide BLAST searches reveal identical matches between the heavy and light chain sequences as annotated in IMGT and SEQ IDs 26 and 29 respectively claimed in patent US8562991 [2]. This matches satralizumab to the Fv4-M73 construct in the patent. ![]() Ligand Activity Visualisation ChartsThese are box plot that provide a unique visualisation, summarising all the activity data for a ligand taken from ChEMBL and GtoPdb across multiple targets and species. Click on a plot to see the median, interquartile range, low and high data points. A value of zero indicates that no data are available. A separate chart is created for each target, and where possible the algorithm tries to merge ChEMBL and GtoPdb targets by matching them on name and UniProt accession, for each available species. However, please note that inconsistency in naming of targets may lead to data for the same target being reported across multiple charts. ✖ |

Summary of Clinical Use ![]() |
Satralizumab was granted EMA orphan drug designation for neuromyelitis optica (NMO) in June 2016. It received its first national approval from Canada in June 2020 [1], and from Japan slightly later that year, for the treatment of neuromyelitis optica spectrum disorder (NMOSD), FDA approval followed in August 2020 with the indication specified as anti-aquaporin-4 (AQP4) antibody positive NMOSD. |
