Pfizer Inc. (NYSE:PFE) has made an announcement that the U.S Food and Drug Administration (FDA) granted a Breakthrough Therapy status to for XALKORI.

XALKORI which is the first ever Tyrosine Kinase Inhibitor to receive the designation is used to treat patients who have been previously treated with MET Exon 14 Alterations for Metastatic Non-Small Cell lung cancer. The Breakthrough Therapy designation for XALKORI was, additionally granted for the treatment of patients with relapsed or refractory systemic anaplastic large cell lymphoma (ALCL) that is anaplastic lymphoma kinase (ALK) positive.

Met 14 alterations

Met is a type of transmembrane tyrosine receptor kinase carried in various cell types. Met 14 alterations are found in about 3% of NSCLC tumors. ALCL which is a rare non-Hodgkin lymphoma is categorized into either ALK-positive or ALK-negative. Even with chemotherapy, many patients with ALCL are prone to relapse hence the need for alternative treatment.

With several patients suffering from cancers that carry these genomic alterations XALKORI is a welcome relief as it promises to transform the lives of the said patients. A biomarker-driven approach like XALKORI is changing cancer treatment methods by ensuring patients get the right medicine for their cancer disease.
