About Kadcyla®

Kadcyla® is an Antibody-Drug Conjugate approved for second-line treatment for metastatic breast cancer (2013) and early Breast Cancer (2019).

Roche continues to strengthen Kadcyla’s market position through development of a variety of combination or adjuvant therapies.

According to the data from Clinicaltrials.gov, at least 78 oncology drugs from various pharmaceutical companies, utilizing agents with differing treatment targets or categories, are being studied in combination or adjuvant clinical trials with Kadcyla to create opportunities in second treatment line setting.  Among treatment programs of HER2-positive breast cancer, NCCN (The National Comprehensive Cancer Network) designated Kadcyla as the one of the second line treatment regimen for unresectable recurrent breast cancer or advanced breast cancer. Kadcyla works as the next line if the combination treatment of first-line drugs pertuzumab and trastuzumab cannot reach satisfying outcomes.
