At three years, 88.3% of people treated with Kadcyla in the adjuvant HER2-positive early breast cancer setting did not have their breast cancer return compared to 77.0% treated with Herceptin, an 11.3% improvement People who have residual disease after neoadjuvant treatment have a worse prognosis than those with no detectable disease Data from the phase III KATHERINE study will be submitted to health authorities globally, including the US Food and Drug Administration and European Medicines Agency Results are being presented at the 2018 San Antonio Breast Cancer Symposium, featured in the press programme and simultaneously published in the New England Journal of Medicine on Wednesday, 5 December 2018 Basel, 5 December 2018 - Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced that the phase III KATHERINE study met its primary endpoint, showing Kadcyla® (trastuzumab emtansine) as a single agent significantly reduced the risk of disease recurrence or death (invasive disease-free survival; iDFS) by 50% (HR=0.50, 95% CI 0.39-0.64, p=3 AEs Thrombocytopenia (decreased platelet count) 5.7% 0.3% Hypertension (high blood pressure) 2.0% 1.2% Radiation-induced skin injury 1.4% 1.0% Peripheral neuropathy (numbness, tingling or pain in the hands or feet) 1.4% 0.0% Neutropenia (decreased neutrophil count) 1.2% 0.7% Hypokalaemia (low blood potassium level) 1.2% 0.1% Fatigue 1.1% 0.1% Anaemia (decrease in red blood cells) 1.1% 0.1% About Kadcyla Kadcyla is an antibody-drug conjugate (ADC) engineered to deliver potent chemotherapy directly to HER2-positive cancer cells, potentially limiting damage to healthy tissues. [2;3] It combines two anti-cancer properties joined together by a stable linker: the HER2-targeting properties of trastuzumab (the active ingredient in Herceptin) and the chemotherapy agent DM1.  Kadcyla is the only ADC approved as a single agent in 104 countries including the US and EU for the treatment of people with HER2-positive metastatic breast cancer who have previously received Herceptin and taxane chemotherapy, separately or in combination. Roche licenses technology for Kadcyla under an agreement with ImmunoGen, Inc. About Roche's medicines for HER2-positive breast cancer Roche has been leading research into the HER2 pathway for over 30 years and is committed to improving the health, quality of life and survival of people with both early and advanced HER2-positive disease. HER2-positive breast cancer is a particularly aggressive form of the disease that affects approximately 15-20% of patients.  Roche has developed three innovative medicines that have helped transform the treatment of HER2-positive breast cancer: Herceptin (trastuzumab), Perjeta (pertuzumab) and Kadcyla (trastuzumab emtansine). Eligibility for treatment with Roche's HER2-targeted medicines is determined via a diagnostic test, which identifies people who will likely benefit from these medicines at the onset of their disease.
