Full title of the trial

A randomized, multicenter, double-blind phase 3 study of amcenestrant (SAR439859) plus palbociclib versus letrozole plus palbociclib for the treatment of patients with ER (+), HER2 (-) breast cancer who have not received prior systemic anti-cancer treatment for advanced disease

Randomizált, multicentrikus, kettős vak, III. fázisú vizsgálat az amcenesztrant (SAR439859) plusz palbociklib kezelés, illetve letrozol plusz palbociklib kezelés összehasonlítására olyan ER(+), HER2(-) emlőrákban szenvedő betegek körében, akik korábban nem kaptak szisztémás daganatellenes terápiát az előrehaladott betegségükre

A.3.1
