The U.S. Food and Drug Administration’s (FDA) final Guidance for Industry on Pathologic Complete Response in Neoadjuvant Treatment of High-Risk Early-Stage Breast Cancer incorporates two changes that ASCO had proposed in comments submitted to the agency on a draft guidance issued in 2012.
The guidance is intended to assist sponsors in designing trials to support marketing approval of drugs and biological products for treating breast cancer in the neoadjuvant setting. The document addresses the use of pathologic complete response in breast cancer as a potential endpoint to support provisional approval under the accelerated approval regulations.
Two areas where FDA made changes consistent with ASCO’s suggestions included:
ASCO cosponsored a workshop with FDA in 2013 on pathologic complete response in high-risk early-stage breast cancer. The guidance includes a statement about implementation that discusses the workshop’s conclusion that the benefits of using pathologic complete response as a measure for accelerated approvals outweigh the risks.
