Immunopharmacology Comments
The TEC family protein tyrosine kinases have been identified as key components of T-cell-receptor activation and signalling. TEC family kinases are expressed predominantly by haematopoietic cells. T cells express ITK, TXK and TEC [2]. ITK inhibition has been extensively expolred as therapeutic option for Th2-driven inflammatory diseases. Despite much effort having been made to discover novel ITK inhibitors, and favourable preclinical discoveries, the majority of the lead compounds have not translated or progressed to the clinic. JTE-051 (structure not disclosed) is currently the only ITK inhibitor under clinical evaluation, and this is being examined in Phase 2 studies as a treatment for rheumatoid arthritis (NCT02919475) and psoriasis (NCT03358290).
