The drug was also approved in the European Union. Nerlynx in combination with Roche's Xeloda was approved'by the Food and Drug Administration for third-line HER2-positive metastatic breast cancer. Meanwhile, several additional studies on Nerlynx targeting different types of breast cancer patient populations as well as other types of cancers are currently underway. A key analysis of Nerlynx is the phase II SUMMIT basket study for treating solid tumors in patients with activating EGFR, HER2 or HER4 mutated cancers.
