Overview

AZD8421 + camizestrant + ribociclib is an investigational **three-drug combination** being tested in clinical trials for the treatment of advanced or metastatic solid tumors, particularly **estrogen receptor positive (ER+), human epidermal growth factor receptor 2 negative (HER2-) breast cancer**. - **AZD8421** is a highly selective **CDK2 inhibitor** developed to overcome resistance to CDK4/6 inhibitors. - **Camizestrant** (AZD9833) is an oral selective estrogen receptor degrader (**SERD**), acting by degrading and antagonizing estrogen receptor (ER) signaling. - **Ribociclib** (Kisqali) is an **oral CDK4/6 inhibitor**, which blocks cell cycle progression. The combination aims to enhance cell cycle inhibition and ER signaling blockade, potentially improving efficacy in patients whose disease is resistant to standard CDK4/6 inhibitors and endocrine therapies. The regimen is delivered orally in trial settings to female patients with advanced breast cancer or high-grade serous ovarian cancer[1][2][3][4][5][6][7][9][10].
