CHK1 Patent Update

Sareum (AIM: SAR), the specialist cancer drug discovery and development business, is pleased to announce that the U.S. Patent and Trademark Office has issued notification of a grant of a patent for one of the inventions associated with the CHK1 cancer programme.

The patent* describes compounds, developed by Sareum and Cancer Research UK funded scientists at the Institute of Cancer Research (ICR), that inhibit the function of CHK1 kinase enzymes and their potential to treat cancer. On 24 September 2013, it was announced that Cancer Research Technology Ltd and the ICR had licenced the CHK1 programme to the Cancer Research Technology Pioneer Fund (CPF) and that CPF, Sareum and BACIT ltd had entered into a co-development collaboration to advance the CHK1 programme into clinical trials. This particular patent provides limited territorial coverage but is part of a wider estate, including two further patent applications published in 2013, which if granted in its current form would provide broad geographical protection for the CHK1 programme currently being pursued. 

* Patent No. US 8,618,121

Sareum’s CEO, Dr Tim Mitchell, commented: “Consistent with the usual business of the Company, the intellectual property estate that underpins the CHK1 programme continues to develop, protecting the asset and enhancing its commercial value”.

About CHK1 Kinase

CHK1 is important in controlling the way many cancer cells respond to DNA damage, which may be a consequence of the cancer itself, or intentionally caused by chemotherapy or radiotherapy. Inhibition of CHK1 affects the ability of the cell to repair this damage and can therefore potentiate the effect of certain chemotherapeutic drugs.  The candidate CHK1 inhibitor to be developed could potentially treat a range of cancers including pancreatic, bowel and non-small cell lung cancer (NSCLC) in combination with DNA-damaging chemotherapy drugs and/or radiotherapy. The inhibitor could also potentially treat certain neuroblastoma and acute myeloid leukaemia (AML) types when dosed alone.
