Karus Therapeutics to Announce Positive New Data from Phase I Relapsed/Refractory B-Cell Lymphoma Trial at ASH

Oxfordshire, UK, 4 December 2019 – Karus Therapeutics Ltd (‘Karus’), a clinical-stage biopharmaceutical company developing precision medicines for cancer, announces that new data will be presented from its KA2237 Phase I study at the ASH Annual Meeting & Exposition in Orlando, Florida, 9 December 2019.

The Phase I clinical trial, conducted at The University of Texas MD Anderson Cancer Center, has examined the safety, tolerability, pharmacokinetic properties and pharmacodynamic effects of KA2237 in patients with relapsed/refractory B-cell lymphoma.

KA2237 is a potent, orally-active and dual-selective PI3 Kinase (PI3K) p110β/δ inhibitor. The p110δ isoform is an attractive therapeutic target, with several known inhibitors demonstrating efficacy in B-cell lymphomas. Karus aims to overcome mechanisms of tumor escape by simultaneously targeting PI3K p110β.

Tim Edwards, Karus’s Executive Chairman, commented:
As we continue in our mission to develop transformative precision medicines for cancer, ASH provides the perfect opportunity to showcase the potential of KA2237 in the treatment of hematological and solid tumors. We are pleased to be presenting our new data and look forward to connecting with more of the hematology community.”

Details of the poster presentation are as follows:

Title: 4099. Results of a First in Human, Dose Ascending, Phase I Study Examining the Safety and Tolerability of KA2237, an Oral p110β/δ Inhibitor in Patients with Relapsed/Refractory (R/R) B-Cell Lymphoma
Time and Date: 18:00–20:00, Monday 9 December
Session: 626. Aggressive Lymphoma (Diffuse Large B-Cell and Other Aggressive B-Cell Non-Hodgkin Lymphomas)—Results from Prospective Clinical Trials: Poster III
