The goal of this Phase 2 clinical trial is to learn if the combination of Camrelizumab and Palbociclib is a safe and effective treatment when given before surgery (neoadjuvant therapy) for patients with esophageal squamous cell carcinoma (ESCC) that can be surgically removed. Camrelizumab is an immunotherapy drug that helps the immune system fight cancer, and Palbociclib is a targeted therapy drug that stops cancer cells from growing.
The main questions it aims to answer are:
Is the combination of Camrelizumab and Palbociclib safe for patients to receive before their surgery? How effective is this treatment combination in shrinking tumors prior to surgery?
