Adebrelimab Combined With Chemotherapy for the Esophageal Squamous Cell Carcinoma

This study is a prospective, single-arm, phase II exploratory clinical trial. The primary endpoint of this study is to evaluate the pathological complete response (pCR) rate after surgery and to assess the safety of neoadjuvant therapy with adebrelimab combined with platinum-based chemotherapy in patients with locally advanced resectable esophageal squamous cell carcinoma (ESCC) at the Second Qilu Hospital of Shandong University. The primary endpoint of this clinical trial is the pathological complete response (pCR) rate, defined as the absence of residual viable tumor cells in the resected specimen, including lymph nodes (ypT0N0M0). Secondary endpoints include the major pathological response (MPR) rate, objective response rate (ORR), treatment-related adverse events (TRAEs) and immune-related adverse events (irAEs), as well as quality of life (QOL) assessments during neoadjuvant immunochemotherapy (nICT). MPR is defined as less than 10% residual viable tumor cells in the primary tumor bed following neoadjuvant therapy and resection. ORR represents the percentage of patients achieving complete response (CR) or partial response (PR). Other secondary measures include the tumor downstaging rate, surgery rate, R0 resection rate (defined as no residual tumor at the resection margins), and perioperative complication rate. Furthermore, overall survival (OS) and relapse-free survival (RFS) are considered exploratory endpoints in this study. By evaluating these diverse endpoints, the investigators aim to comprehensively assess the efficacy, safety, and overall impact of the nICT approach in patients with locally advanced resectable ESCC. Additionally, it is planned to construct 20 pairs of esophageal squamous cell carcinoma and adjacent normal esophageal squamous epithelial organoids, laying the groundwork for future in-depth exploration of the mechanisms underlying esophageal carcinogenesis and progression, as well as functional studies of specific genes.

Study of Rituximab or Tocilizumab for Patients With Steroid-Dependent Immune-Related Adverse Events (irAEs)

The purpose of this study is to examine how effective rituximab or tocilizumab are in treating side effects for people who are receiving immunotherapy treatment requiring prolonged steroid use. Immune-related side effects are caused by the activation of the immune system. Because rituximab and tocilizumab have been shown to effectively in treating other diseased that involve immune system activation, this study seeks to evaluate how effective they will be in treating immune-related side effects in people receiving immunotherapy treatment for cancer.

A Single-cell Approach to Identify Biomarkers of Pulmonary Toxicity for Immune Checkpoint Blockade

The main goal of this prospective non-interventional exploratory monocentric study is to characterize the immune cell composition of bronchoalveolar lavage (BAL) fluid from cancer patients experiencing cancer therapy-induced pneumonitis on a single-cell scale. These mechanistic insights can directly lead to putative diagnostic biomarkers and therapeutic targets. A second highly clinically relevant hypothesis is that single-cell profiling of blood samples will reveal circulating biomarkers of ICB toxicity, making non-invasive diagnosis feasible.
