LONDON, Feb 27 (Reuters) - European health regulators said on Friday they had recommended approval of a drug for advanced lung cancer developed by Swiss drugmaker Novartis that is intended to treat patients with a specific genetic mutation.

Zykadia, or ceritinib, is from a new class medicines known as ALK inhibitors. It was approved in April 2014 in the United States.

It is designed for use in non-small cell lung cancer patients who have previously been treated with Pfizer's Xalkori, another ALK inhibitor.

Between 2 and 7 percent of non-small cell lung cancer patients have the specific mutation of the ALK (anaplastic lymphoma kinase) protein for which such treatment is targeted. They are often non smokers.
