Cyclacel Announces Notice of Grant of New European Patent Covering Sapacitabine Pharmaceutical Formulations

Granted Patent Broadens Exclusivity of Sapacitabine


BERKELEY HEIGHTS, N.J., Feb. 21, 2018 (GLOBE NEWSWIRE) -- Cyclacel Pharmaceuticals, Inc. (NASDAQ:CYCC) (NASDAQ:CYCCP) ("Cyclacel" or the "Company"), a biopharmaceutical company developing oral therapies that target the various phases of cell cycle control for the treatment of cancer and other serious disorders, today announced the receipt of a notice from the European Patent Office of the intention to grant a patent (EP1962814) including claims to novel pharmaceutical formulations of sapacitabine. The European patent will provide exclusivity until December 2026 excluding any extensions. Equivalent patents have been granted in the United States (US 8,497,291 expiring in January 2030) and other countries.

"This European notice of grant enhances the intellectual property estate related to sapacitabine. The relevant patent family is an important layer of our strategy of building on sapacitabine's exclusivity.  It supplements existing composition of matter, dosing regimen and combination treatment patent protection in major global markets extending into 2030," said Spiro Rombotis, President and Chief Executive Officer of Cyclacel. "We look forward to providing updates on our progress with sapacitabine, in terms of regulatory discussions regarding the data from our SEAMLESS study in acute myeloid leukemia and updates from our ongoing Phase 1 extension study evaluating the sequential regimen of sapacitabine and seliciclib in patients with BRCA positive, breast, ovarian and pancreatic cancers."

About sapacitabine

Sapacitabine (CYC682), an orally-available nucleoside analogue, is currently being studied in an ongoing, Phase 1 study evaluating a sequential regimen of sapacitabine and seliciclib, a first generation CDK inhibitor. Parts 1 and 2 of the study evaluated an enriched population of approximately 76 patients with advanced cancers and were reported at ASCO 2016.  The ongoing extension of part 1 enrolled 20 patients with BRCA positive advanced breast cancers and is in the follow-up stage. Part 3 of the study has been opened for enrolment with the objective of testing a revised dosing schedule in additional patients, including BRCA positive patients with advanced ovarian and pancreatic cancers.

Sapacitabine is also the subject of the Phase 3 SEAMLESS study of elderly patients with acute myeloid leukemia, or AML. Data from this completed study were reported on December 11, 2017 in an oral presentation at the 59th ASH Annual Meeting.  Sapacitabine has been evaluated in both hematological cancers and solid tumors. Over 1,000 patients have received sapacitabine in Phase 1, 2 and 3 studies.
