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].

Phase I study of tirabrutinib (ONO-4059/GS-4059) in patients with relapsed or refractory B-cell malignancies in Japan.[Pubmed:30815927]
Cancer Sci. 2019 Feb 27.
We evaluated the safety, efficacy, pharmacokinetics, pharmacodynamics and predictive biomarkers of tirabrutinib, a second-generation, enhanced-selectivity Bruton's tyrosine kinase inhibitor in Japanese patients with relapsed/refractory B-cell non-Hodgkin lymphoma (B-cell NHL) and chronic lymphocytic leukemia (CLL). This was an open-label, multicenter, phase I study. Seventeen patients (male N = 8) with a median age of 70 years were enrolled in 4 dose cohorts (160 mg once daily [N = 3], 320 mg once daily [N = 3], 480 mg once daily [N = 4] and 300 mg twice daily [N = 7]); 4 patients had continued tirabrutinib administration as of 4 January 2018. The maximum tolerated dose was not reached. Pneumonitis (N = 1) was the dose-limiting toxicity for 300 mg twice daily. Common adverse events (AEs) were rash (35.3%) and vomiting (29.4%). Eight patients (47.1%) developed grade >/=3 AEs: neutropenia (23.5%), anemia (11.8%) and leukopenia (11.8%) were frequent. The overall response rate (>/=PR) was 76.5% (13/17 patients), including 4 DLBCL patients with no CD79A/B or MYD88 mutations, and 1 CLL patient with a TP53 mutation, providing promising data for future developments. Of 16 patients with measurable lesions during the screening period, 12 showed >/=50% reductions in tumor diameter. In many patients, the tumor size decreased soon after beginning treatment. The maximum serum concentration for tirabrutinib was 611, 1220, 1280 and 886 ng/mL on Day 1 and 484, 971 1940, and 961 ng/mL on Day 28 for Cohorts 1-4, respectively. Tirabrutinib pharmacokinetics were linear, with little accumulation following multiple doses. Tirabrutinib was well tolerated and showed promising efficacy for B-cell NHL/CLL.
Homogeneous BTK Occupancy Assay for Pharmacodynamic Assessment of Tirabrutinib (GS-4059/ONO-4059) Target Engagement.[Pubmed:30011241]
SLAS Discov. 2018 Oct;23(9):919-929.
Bruton's tyrosine kinase (BTK) is a clinically validated target for B-cell leukemias and lymphomas with FDA-approved small-molecule inhibitors ibrutinib and acalabrutinib. Tirabrutinib (GS-4059/ONO-4059, Gilead Sciences, Inc., Foster City, CA) is a second-generation, potent, selective, irreversible BTK inhibitor in clinical development for lymphoid malignancies, including chronic lymphocytic leukemia (CLL) and diffuse large B-cell lymphoma (DLBCL). An accurate pharmacodynamic assay to assess tirabrutinib target coverage in phase 1/2 clinical studies will inform dose and schedule selection for advanced clinical evaluation. We developed a novel duplex homogeneous BTK occupancy assay based on time-resolved fluorescence resonance energy transfer (TR-FRET) to measure free and total BTK levels in a multiplexed format. The dual-wavelength emission property of terbium-conjugated anti-BTK antibody served as the energy donor for two fluorescent energy acceptors with distinct excitation and emission spectra. The assay was characterized and qualified using full-length purified recombinant human BTK protein and peripheral blood mononuclear cells derived from healthy volunteers and patients with CLL. We demonstrated assay utility using cells derived from lymph node and bone marrow samples from patients with CLL and DLBCL. Our TR-FRET-based BTK occupancy assay provides accurate, quantitative assessment of BTK occupancy in the clinical trial program for tirabrutinib and is in use in ongoing clinical studies.
Novel synthetic drugs currently in clinical development for chronic lymphocytic leukemia.[Pubmed:28942659]
Expert Opin Investig Drugs. 2017 Nov;26(11):1249-1265.
INTRODUCTION: Over the last few years, several new synthetic drugs, particularly Bruton's tyrosine kinase (BTK), phosphatidylinositol 3-kinase (PI3K) and BCL-2 inhibitors have been developed and investigated in chronic lymphocytic leukemia (CLL). Areas covered: This review highlights key aspects of BTK, PI3K and BCL-2 inhibitors that are currently at various stages of preclinical and clinical development in CLL. A literature review of the MEDLINE database for articles in English concerning CLL, B-cell receptor, BCL-2 antagonists, BTK inhibitors and PI3K inhibitors, was conducted via PubMed. Publications from 2000 through July 2017 were scrutinized. The search terms used were acalabrutinib, ACP-196, BGB-3111, ONO-4059, GS-4059, duvelisib, IPI-145, TGR-1202, copanlisib, Bay 80-6946, buparlisib, BKM-120, BCL-2 inhibitors, venetoclax, ABT-263, navitoclax, CDK inhibitors, alvocidib, flavopiridol, dinaciclib, SCH 727,965, palbociclib, PD-0332991, in conjunction with CLL. Conference proceedings from the previous five years of the ASH and EHA Annual Scientific Meetings were searched manually. Additional relevant publications were obtained by reviewing the references from the chosen articles. Expert opinion: The use of new synthetic drugs is a promising strategy for the treatment of CLL. Data from ongoing and future clinical trials will aid in better defining the status of new drugs in the treatment of CLL.
