Giredestrant demonstrates efficacy in early-stage breast cancer
Roche has reported that its selective estrogen receptor degrader (SERD), giredestrant, has demonstrated significant clinical benefit in pivotal Phase III trials for adjuvant early-stage ER-positive, HER2-negative breast cancer, as well as strong efficacy in advanced breast cancer settings. These results position giredestrant as the first oral SERD to show meaningful clinical benefit in this indication. The announcement sparked a notable 7% jump in Roche’s share price in a single day.
