Daiichi Sankyo Company, Limited (hereafter, Daiichi Sankyo) today announced the first patient with triple negative breast cancer (TNBC) has been dosed in the ongoing phase 1 study assessing DS-1062, a TROP2 directed DXd antibody drug conjugate (ADC).
Patients with TNBC, an aggressive subtype of breast cancer, have limited treatment options beyond standard chemotherapy. High TROP2 expression has been reported in up to 80 percent of patients with TNBC.
“Following the promising preliminary results reported with DS-1062 in patients with non-small cell lung cancer, we have expanded the study to include patients with triple negative breast cancer,” said Gilles Gallant, BPharm, PhD, FOPQ, Senior Vice President, Global Head, Oncology Development, Oncology R&D, Daiichi Sankyo. “We continue to follow the science to determine whether DS-1062, designed with our proprietary DXd ADC technology, could serve as a new TROP2 directed therapy option for patients with TNBC and other cancers.”
