• Indications: Nerlynx® (neratinib) tablets, for oral use, is a kinase inhibitor indicated:

    • As a single agent, for the extended adjuvant treatment of adult patients with early-stage HER2-positive breast cancer, to follow adjuvant trastuzumab-based therapy.
    • In combination with capecitabine, for the treatment of adult patients with advanced or metastatic HER2-positive breast cancer who have received two or more prior anti-HER2 based regimens in the metastatic setting.
  • Protect against progression in HER2+ metastatic breast cancer1,*

    * After ≥2 prior anti-HER2—based regimens in the metastatic setting.

    Nerlynx + capecitabine may help protect against progression1,2

    PFS in patients with HER2+ mBC vs lapatinib + CAPECITABINE1,2

    29% PFS rate at 12 months vs 15% with lapatinib + capecitabine1

    • Nerlynx + capecitabine significantly improved median PFS vs lapatinib + capecitabine: 5.6 months with Nerlynx + capecitabine vs 5.5 months with lapatinib + capecitabine (HR=0.76; 95% CI: 0.63-0.93; P=0.0059)1
    • There was no significant difference in OS between Nerlynx + capecitabine vs lapatinib + capecitabine: 21.0 months with Nerlynx + capecitabine vs 18.7 months with lapatinib + capecitabine (HR=0.88; 95% CI: 0.72-1.07; P=0.2086)1
    • The total number of patients remaining in the study at 24 months was 11 (9 patients receiving NERLYNX + capecitabine, 2 patients receiving lapatinib + capecitabine).1
    • CI: confidence interval; HR: hazard ratio; mBC: metastatic breast cancer; OS: overall survival; PFS: progression-free survival.
