The use of an antibody drug conjugate, glembatumumab vedotin (CDX-011), for the treatment of breast cancer

Abstract

Introduction: Breast cancer (BC) is the most common malignancy in women in the USA. Despite the multi-modality treatments that are currently available, advanced BC has a persistent and unacceptable mortality rate. The need for new therapeutic strategies is extremely high. Experimental approaches with targeted therapies such as antibody drug conjugates provide hope for future treatment possibilities.

Areas covered: The development status and the possible role of antibody-mediated cytotoxic therapy are discussed in the setting of advanced BC. An overview of, mechanism of action, preclinical and Phase I/II results of glembatumumab vedotin (CDX-011) are discussed.

Expert opinion: The evidence that the glycoprotein NBM (GPNMB) target is a relevant target in BC, along with data showing that CDX-011 is safe and active in patients with advanced BC, provide a strong rationale to continue to explore this drug in patients with GPNMB-expressing breast tumors.
