Background

Description:

IC50: 2.2 nM for Btk kinase activity

Bruton’s tyrosine kinase (Btk) is a key regulator of the B-cell receptor (BCR) pathway and abberant BCR signaling has been implicated in the survival of malignant B-cells. Previous studies indicate that targeting Btk is effective in the treatment of B-cell malignancies. ONO-4059 is a highly potent and selective oral Btk inhibitor.

In vitro: ONO-4059 inhibited the TMD-8 cell growth and Btk phosphorylation in a concentration-dependent manner. Furthermore, the decrease in Btk phosphorylation subsequently down-regulated Erk phosphorylation. After the combination of ONO-4059 with doxorubicin, etoposide, vincristine and dexamethasone, increased apoptosis ratio was observed, 25, 20, 17 and 29%, respectively [1].

In vivo: For the 100-200 mm3 tumour groups, tumour growth inhibition at the final treatment day was 23% in QD, 72.9% in BD and 100% in dose mixed in food, groups respectively. For the 400-450 mm3 tumour groups, no growth inhibition was observed in the QD group and, growth inhibitions of 27.5% in BD and 100% in dose mixed in food were observed. The PK concentration and phosphorylated Btk inhibition levels of those animals whose dose was mixed in with food were higher than that of other treatment groups [2].

Clinical trial: ONO-4059 is a highly potent and selective oral Btk inhibitor that shows a favourable safety profile along with promising efficacy in this difficult-to-treat patient population with relapsed/refractory B-Cell lymphoma [3].
