Checkpoint Therapeutics Announces Issuance of Two New Patents for EGFR Inhibitor CK-101

Checkpoint Therapeutics (NASDAQ:CKPT) has announced that the European Patent Office (EPO) has issued a composition of matter patent for the company’s CK1-10 third generation growth factor receptor inhibitor.

As quoted in the press release:

European Patent No. 3035936 specifically covers the compound CK-101 and a broad range of related compounds, salts and pharmaceutical compositions, including various dosage forms of such pharmaceutical compositions. It also covers certain uses of such compounds or salts in treating cancer or a disorder mediated by EGFR or NSCLC, either alone or in combination with an additional anti-cancer and/or cytotoxic agent.

The U.S. Patent and Trademark Office previously issued a U.S. counterpart composition of matter patent for CK-101 (U.S. Patent No. 9,550,770). Together, the patents cover CK-101 in the U.S. and Europe through at least August 2034, not including any potential patent term extension in the U.S. under the Hatch-Waxman Act.

Additionally, in January 2019 the U.S. Patent and Trademark Office issued U.S. Patent No. 10,172,868, which claims a method of treating a patient diagnosed with NSCLC, metastatic NSCLC or NSCLC with EGFR mutations that is comprised of administering a therapeutically effective amount of CK-101. This U.S. patent is scheduled to expire in August 2034, not including any potential patent term extension.

“We are very pleased by the issuance of a European composition of matter patent for CK-101, in addition to a second U.S. patent, as they represent important milestones in our intellectual property strategy,” said James F. Oliviero, President and CEO of Checkpoint. “We plan to continue to expand and fortify our intellectual property estate for CK-101 in the U.S. and abroad as we advance CK-101 toward Phase 3 trial initiation, which we expect later this year.”
