Sovleplenib is a novel, investigational, selective small molecule inhibitor for oral administration targeting the spleen tyrosine kinase (Syk).
Syk is said to be a major component in B-cell receptor and Fc receptor signalling. It is an established target for treating multiple subtypes of B-cell lymphomas and autoimmune disorders.
The company stated that the small molecule inhibitor is also being investigated in various cancers including indolent non-Hodgkin’s lymphoma, autoimmune hemolytic anemia, and multiple subtypes of B-cell malignancies in China, Europe, and the US.
In November last year, Hutchmed reported positive data from the Phase III FRUTIGA study of fruquintinib for the treatment of advanced gastric cancer or gastroesophageal junction (GEJ) adenocarcinoma.
