"At our virtual R&D Day in May, we outlined our vision for expanding and driving progress in our pipeline of clinical programs that target dysregulated transcription factors and the regulatory networks within cancerous cells. This included unveiling the development strategy for our SYK inhibitor portfolio, which comprises entospletinib (ENTO) and LANRA. These differentiated clinical-stage investigational development candidates have the potential to address the mutations that are present in more than two-thirds of patients with AML," said Norbert Bischofberger, Ph.D., president and CEO. "We are poised to initiate our registrational Phase 3 trial later this year to support potential accelerated approval of ENTO in patients newly diagnosed with NPM1-mutated AML. With the recent FDA clearance of our IND for LANRA in relapsed or refractory FLT-3 mutant AML, we plan to launch our second SYK inhibitor clinical trial in the fourth quarter of 2021, when we also expect to report initial Phase 1 data from our trial of KB-0742, our potent oral, highly selective cyclin dependent kinase 9 inhibitor. I am proud of our Company’s momentum and anticipate multiple important inflection points in the coming months."
Recent Company Highlights
Received clearance from U.S. Food and Drug Administration (FDA) for the IND application of LANRA, a next-generation spleen tyrosine kinase (SYK) inhibitor. The first of two planned Phase 1/2 clinical trials is expected to initiate in Q4 2021 in patients with relapsed or refractor FLT3-mutated AML and will include a dose-escalation and an expansion cohort study design. The first stage will evaluate initial safety, pharmacokinetic (PK) and anti-leukemic activity of escalating once-daily doses of LANRA in combination with gilteritinib. Initial data from this first stage of the trial are anticipated to be available in the second half of 2022.
On track to initiate the Phase 3 trial of ENTO in the second half of 2021 with a pivotal data readout expected in the second half of 2023.
This trial will assess measurable residual disease (MRD) negative complete response (CR) as the primary endpoint to support potential accelerated approval in patients newly diagnosed with NPM1-mutated AML.
Anticipates reporting initial safety, PK and pharmacodynamic (PD) data from Phase 1 trial of KB-0742, a highly selective, orally bioavailable cyclin dependent kinase 9 (CDK9) inhibitor being developed to treat MYC-amplified solid tumors, in the fourth quarter of 2021. The company presented preclinical data for KB-0742 at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting in April 2021, which showed CDK9 inhibition on an intermittent dosing schedule with KB-0742 resulted in sustained inhibition of tumor growth in multiple types of solid tumors. The findings suggest that genomic amplification of MYC, a well-characterized transcription factor and a long-recognized driver of cancer, is a key factor of sensitivity to CDK9 inhibition.
Hosted a virtual R&D Day in May 2021 to discuss the company’s development strategy for the SYK inhibitors ENTO and LANRA, expectations for the upcoming Phase 1 data readout for KB-0742 and potential populations for expansion cohorts of a Phase 1/2 trial, along with an overview of the company’s differentiated drug discovery platform and future pipeline programs.
