This March, the FDA released updated guidance on the naming of biologics, biosimilars, and interchangeable biosimilars. In the document, the FDA indicated that it no longer intends to retroactively give approved biologics 4-letter suffixes devoid of meaning, but it will continue to assign suffixes to newly approved innovator biologics, biosimilars, or interchangeable biosimilars. In addition, FDA does not intend to add suffixes to the names of transition products. This week, the comment period on the updated guidance closed, and the FDA heard from a variety of stakeholders who asked the agency to change its direction.

Yesterday, the FDA approved Roche’s ado-trastuzumab emtansine (Kadcyla) for the adjuvant treatment of HER2-positive early breast cancer in patients who have residual invasive disease after neoadjuvant taxane- and trastuzumab-based therapy.
