Study Overview
Brief Summary
The purpose of this study is to explore the safety and feasibility of anti-programmed cell death 1(PD-1) immunotherapy, Camrelizumab, combined with cyclin-dependent kinase 4/6 blockade, Palbociclib, as a new neoadjuvant treatment regimen for patients with resectable esophageal squamous cell carcinoma (ESCC).

- •The patients with severe systematic intercurrent diseases, including active infection or poorly controlled diabetes, coagulation disorders, hemorrhagic tendency, or those undergoing thrombolysis or anticoagulant therapy etc. are excluded from the study.
- •Female participants who test positive for a serum pregnancy test, are in the lactation period, or are at a childbearing stage and unwilling to use contraception measures during the research are excluded.
- •Received any investigational drug within 4 weeks prior to the first dose, or concurrently enrolled in another clinical trial.
- •Any other factors that are not suitable for inclusion in this study judged by investigators.
Arms & Interventions
Camrelizumab+Palbociclib(100mg) 3 patients
For palbociclib, there is 2 dose levels, 100mg qd and 125 mg qd, and if no patients experience DLT on 100mg level, 125mg level will be administered.
Intervention: Camrelizumab (Drug)
Camrelizumab+Palbociclib(100mg) 3 patients
For palbociclib, there is 2 dose levels, 100mg qd and 125 mg qd, and if no patients experience DLT on 100mg level, 125mg level will be administered.

Outcomes
Primary Outcomes
Safety of combination camrelizumab and palbociclib as assessed by number of participants who experience adverse events
Time Frame: up to 15 weeks
Number of participants who experience grade 1 or higher adverse events, as defined by Common Terminology Criteria for Adverse Events version 5.0 (CTCAE v5.0)
Feasibility of combination camrelizumab and palbociclib as assessed by number of participants who experience adverse events
Time Frame: up to 15 weeks
Patients proceed to surgery without experiencing prolonged treatment-related delays. An extended treatment-related delay will be considered if it exceeds 37 days from the initially scheduled surgery date. In terms of feasibility, if there is any treatment toxicity of any grade that could adversely impact prognosis, as judged by the investigators, the planned operative date should be re-evaluated.
Secondary Outcomes
- Maximum Tolerated Dose (MTD) of palbociclib as determined by number of participants with dose limiting toxicities (DLT)(up to 15 weeks)
- Major Pathologic Response(up to 15 weeks)
- Objective response rate (ORR)(up to 15 weeks)
- Progression free survival(PFS)(Up to 2 years)
- Overall survival (OS)(Up to 2 years)
