This Phase II trial evaluates the efficacy and safety of Serplulimab combined with S1 chemotherapy in patients with inoperable, locally advanced esophageal squamous cell carcinoma after concurrent chemoradiation. The primary endpoint is the one-year progression-free survival rate. Secondary measures include clinical response rates, overall survival, duration of response, and safety profiles. Exploratory goals focus on the potential of biomarkers like PD-L1 and ctDNA to predict treatment outcomes. Treatment involves initial chemoradiation followed by consolidation with Serplulimab and S1, continuing for up to 12 months or until disease progression or unacceptable toxicity.
Patients diagnosed with locally advanced esophageal squamous cell carcinoma (ESCC) who failed to induction chemo(immuno)therapy had poor prognosis. Radiotherpy was an important and effective treatment in treating ESCC. The present study is a one-arm trial that seeks to evaluate the efficacy in patients with unresectable ESCC. The study objectives include R0 resection rate, complete pathological response and treatment toxicity, etc. Nimotuzumab is a recombinant humanized monoclonal antibody against EGFR. Its efficacy and safety in patients with esophageal cancer have been confirmed by many studies. The current prospective phase II study aimed to evaluate the efficacy and safety of a combination regimen comprising chemotherapy with nimotuzumab and S-1 and concurrent radiotherapy for patients who are not sensitive to induction chemo(immuno)therapy.
The goal of this observational study was to explore the safety and efficacy of short course hypofractionated radiotherapy combined with Raltitrexed and Tislelizumab in the treatment of patients with relapsed or advanced esophageal squamous cell carcinoma.
The goal of this clinical trial is to learn if immune microenvironment modification could improve the effect of chemoradiotherapy for patients with local advanced esophageal squamous cell carcinoma. The main questions it aims to answer are: 1. Does immune microenvironment could be modified by medium dose of three drugs (paclitaxel, cisplatin, 5-FU), PD1 checkpoint inhibitor, probiotics, and thymosin α1？ 2. Does induction and consolidation of PD1 checkpoint inhibitor improve the effect of chemoradiotherapy for patients with esophageal cancer? This is a single arm study. Participants will: 1. Take one cycle of induction chemotherapy (paclitaxel, cisplatin, 5-FU) and immunotherapy (Sintilimab), two cycle of concurrent chemoradiotherapy, one cycle of consolidation chemo-immunotherapy, and then 1 year of immunotherapy. 2. Take probiotics (Clostridium Butyricum) for 1 year and thymosin alpha-1 daily during radiotherapy.
The purpose of this study is to determine safety and preliminary efficacy of amivantamab monotherapy, amivantamab in addition to pembrolizumab, and amivantamab in addition to paclitaxel in participants with recurrent/metastatic head and neck cancer. The study will also confirm the recommended Phase 2 combination dose (RP2CD) for amivantamab in addition to paclitaxel.
Previous trials, such as ADURA and CTONG, have demonstrated the benefits of neoadjuvant targeted therapy in patient with EGFR mutations , which can effectively reduce the extent of tumors and improve the survival outcomes. However, clinical trials of neoadjuvant targeted therapy in NSCLC have rarely enrolled patients with EGFR-mutated lung squamous cell carcinoma due to its rarity, which means that the safety and feasibility of neoadjuvant osimertinib in patients with resectable stage II-IIIB EGFR-mutated lung squamous cell carcinoma remains controversial.
Bronchial arterial infusion plus bronchial arterial chemoembolization (BAI-BACE) has been reported as non-first-line therapy to treat lung cancer in many hospitals in China. BAI, which uses chemotherapeutic drugs directly injected into the tumor and achieved a high concentration in a short time to kill the tumor. Then BACE could seal off the tumor vessels. In this study, we aim to describe the efficacy and safety of BAI-BACE as non-first-line for advanced lung squamous cell carcinoma.
This is a multi-center, open-label, Phase 0 substudy designed to evaluate the localized pharmacodynamics (PD) of rilvegostomig, volrustomig, and sabestomig within the tumor microenvironment (TME) when administered intratumorally in microdose quantities via the CIVO device in patients presenting with Head and Neck Squamous Cell Carcinoma (HNSCC) with a surface accessible lesion, who are scheduled for tumor and/or regional node dissection as part of their standard treatment. PD effects due to injected investigational agents will be compared to those elicited by pembrolizumab alone, which will also be injected in microdose quantities via the CIVO device.
The goal of this clinical trial is to learn if PD-1 monoclonal antibody combined with radical chemoradiotherapy works to treat rectal squamous cell carcinoma (rSCC). lt will also learn about the safety of the regime. The main questions it aims to answer are: Does PD-1 monoclonal antibody combined with radical chemoradiotherapy improve survival prognosis? What is the complete response rate (CCR) of the regime？ Researchers will compare PD-1 monoclonal antibody combined with radical chemoradiotherapy to previous study to see if this regime works to treat rSCCs. Participants will receive chemotherapy with DDP and 5-FU, immunotherapy with PD-1 monoclonal antibody and radiotherapy with a total dose of 50-54GY.
