LONDON, Oct. 04, 2019 (GLOBE NEWSWIRE) — Hutchison China MediTech Limited (“Chi-Med”) (AIM/Nasdaq: HCM) has initiated an international Phase I/Ib study of HMPL-523, its novel spleen tyrosine kinase (“Syk”) inhibitor, in patients with relapsed or refractory lymphoma. The first patient was dosed on September 26, 2019 in the U.S.
The international clinical study, with sites in the U.S. and Europe, is a multi-center, open-label, two-stage study, including dose escalation and expansion, investigating the effects of HMPL-523 administered orally to patients with relapsed or refractory lymphoma. The primary outcome measures are safety and tolerability. Secondary outcomes include pharmacokinetic (PK) measurements and preliminary efficacy such as objective response rate (ORR). The lead investigator of the study is Dr. Nathan Fowler, Associate Professor, Department of Lymphoma/Myeloma, The University of Texas MD Anderson Cancer Center, Houston, TX. Additional details may be found at clinicaltrials.gov, using identifier NCT03779113.
This study complements the ongoing Phase Ib dose expansion program of HMPL-523 in Australia (clinicaltrials.gov identifier: NCT02503033) and China (clinicaltrials.gov identifiers: NCT02857998 and NCT03483948) addressing a broad range of hematological cancers. Preliminary results of the dose escalation stage in a Phase I study in China of HMPL-523 in patients with relapsed or refractory B-cell lymphomas were presented in 20181. Outside of oncology, HMPL-523 is in Phase I study in patients with Immune Thrombocytopenia (ITP) in China (clinicaltrials.gov identifier: NCT03951623).
About HMPL-523
HMPL-523 is a novel, highly selective and potent small molecule inhibitor for oral administration targeting spleen tyrosine kinase, also known as Syk. Syk is a major component in B-cell receptor signaling and is an established therapeutic target in multiple subtypes of B-cell lymphomas. Because B cell malignancies are heterogeneous and patients commonly experience relapse despite current therapies, there is a recognized need for new therapeutics.

These forward-looking statements reflect Chi-Med’s current expectations regarding future events, including its expectations for the clinical development of HMPL-523, including in combination with azacitidine, plans to initiate clinical studies for HMPL-523 as a monotherapy or in combinations, its expectations as to whether such studies would meet their primary or secondary endpoints, and its expectations as to the timing of the completion and the release of results from such studies. Forward-looking statements involve risks and uncertainties. Such risks and uncertainties include, among other things, assumptions regarding enrollment rates, timing and availability of subjects meeting a study’s inclusion and exclusion criteria, changes to clinical protocols or regulatory requirements, unexpected adverse events or safety issues, the ability of drug candidate HMPL-523 as a monotherapy or in combinations to meet the primary or secondary endpoint of a study, to obtain regulatory approval in different jurisdictions, to gain commercial acceptance after obtaining regulatory approval, the potential market of HMPL-523 for a targeted indication and the sufficiency of funding. In addition, as one of the Phase I studies in China relies on the use of azacitidine as combination therapeutics with HMPL-523, such risks and uncertainties include assumptions regarding the safety, efficacy, supply and continued regulatory approval of azacitidine.
