Breast cancer biosimilar shows equivalency to brand
Breast cancer biosimilar shows equivalency to brandTwo new major studies on a biosimilar to trastuzumab (Herceptin, Genentech) to treat HER2-positive metastatic breast cancer and HER2-positive gastric cancer demonstrated equivalency.
Continued advances in cancer outcomes unveiled at ASCOLeading cancer drugs reduced the risk of death by half for people with lung cancer and assisted patients with HER2-positive breast cancer live longer without the disease recurring. The findings were just two of the numerous important study results presented at the 51st Annual Meeting of the American Society of Clinical Oncology (ASCO) meeting in Chicago, Ill., this week.
Unprecedented efficacy of latest HER2-targeting agents can extend life but at significant costBreast cancer is the second most common cancer in the world, and the most common cancer in women. In 2013, approximately 261,000 women were diagnosed with this disease in the United States alone.1 When diagnosed in the earliest stages, such as ductal carcinoma in situ and stage 1, the 5-year survival rate is almost 100%. If diagnosed later, or if the disease progresses to advanced breast cancer, survival rapidly decreases. Human epidermal growth factor receptor 2 (HER2)-positive breast cancer represents about 20% of cases, and before the introduction of HER2-targeting therapies, had the worst prognosis of all breast cancer subtypes.
Distribution changes for top cancer drugs cause hospitals to protestGenentech has announced a major change in the distribution process for their 3 top cancer drugs: Avastin (bevacizumab), Herceptin (trastuzumab), and Rituxan (rituximab). Now, distribution of the drugs to hospitals and clinics will be restricted to authorized specialty distributors.
Breast cancer drug may play role in bladder cancerMayo Clinic researchers have found amplification of HER2, a known driver of some breast cancers, in micropapillary urothelial carcinoma and have shown that the presence of HER2 amplification is associated with particularly aggressive tumors.
