The phase III KEYNOTE-522 trial evaluating Keytruda, Merck’s anti-PD-1 therapy, met its overall survival endpoint, in combination with chemotherapy as pre-operative treatment and then continuing as a single agent after surgery for the treatment of patients with high-risk early-stage triple-negative breast cancer.
The phase III persevERA Breast Cancer study, evaluating investigational giredestrant in combination with palbociclib for people with oestrogen receptor (ER)-positive, human epidermal growth factor receptor 2 (HER2)-negative, locally advanced or metastatic breast cancer, did not meet its primary objective of a statistically significant improvement in progression-free survival in the intent-to-treat population versus letrozole plus palbociclib, but a numerical improvement was observed.
