Filter by:To explore the efficacy and safety of immune checkpoint inhibitor combined with endostar and chemotherapy in the treatment of advanced lung squamous cell carcinoma (stage IIIB-IV).
This is a multi-center, open-label, dose-escalation and cohort-expansion phase I clinical study to evaluate the safety and tolerability, pharmacokinetics profile, efficacy and immunogenicity of IMM2520 in subjects with advanced solid tumors.
The goal of this observational study is to explore whether ctDNA dynamic monitoring plus AI-based pathology can more effectively predict the therapeutic effect of neoadjuvant chemoimmunotherapy for resectable lung squamous cell carcinoma, so as to accurately guide clinical diagnosis and treatment.
This study is a phase III, multicenter, prospective randomized controlled clinical study comparing the efficacy of non-surgical esophageal squamous cell carcinoma with radical chemoradiotherapy and radical chemoradiotherapy combined with consolidation chemotherapy. The survival time and side effects of patients were observed and compared.
The guidelines for locally advanced head and neck squamous cell carcinoma currently recommend surgery / radiotherapy / chemotherapy / targeted therapy. However, the median PFS of patients with high risk factors after comprehensive treatment was about 17 months, and the 2-year PFS rate was about 40 %. The KEYNOTE-048 study showed that PD-1 monoclonal antibody alone or in combination with chemotherapy significantly improved survival and was safe for recurrent / metastatic head and neck squamous cell carcinoma. Therefore, PD-1 monoclonal antibody has become the first-line treatment of metastatic head and neck squamous cell carcinoma. For locally advanced head and neck squamous cell carcinoma, the existing studies on immunotherapy for neoadjuvant or concurrent chemoradiotherapy have not been clearly concluded. We previously used PD-1 monoclonal antibody for the maintenance treatment of patients after the first-line treatment of locally advanced head and neck squamous cell carcinoma, without residual tumor, which showed a trend of prolonged survival. Therefore, this study intends to explore whether the maintenance treatment of PD-1 monoclonal antibody terripril can further improve the survival of patients with locally advanced head and neck squamous cell carcinoma with high risk factors and no residual tumor after first-line comprehensive treatment, and the safety is good.
Rationale: Vulvar squamous cell carcinoma (VSCC) is a rare cancer with a rising incidence. Standard treatment comprises wide local excision of the primary tumour and inguinal lymph nodes and sometimes (chemo) radiotherapy. Treatment is associated with impressive and long-lasting morbidity, sexual and psychological dysfunction and wound healing disorders. Recurrent disease develops in up to 40% of all treated patients. The unmet need, therefore, is a less radical and more effective treatment for VSCC. Hypothesis: Based on the local immune profile in a large fraction of patients with primary VSCC the investigators hypothesize that neoadjuvant PD-1 checkpoint inhibition may reinvigorate tumor-specific T cells resulting in a reduced tumor load, potentially leading to less radical surgery and reduces the recurrence rate. The primary objectives of this trial are to study clinical efficacy and immune activation of neoadjuvant PD-1 blockade in VSCC. Study design: This is a prospective, multicenter phase II non-controlled clinical trial in 40 VSCC patients. Study population: Clinically diagnosed FIGO I-III primary VSCC patients to be treated with surgery with curative intent. Intervention (if applicable): Anti-PD1 antibody pembrolizumab, 200 mg IV Q3W for a total of 2 administrations per patient over a period of 6 weeks prior to surgery. Main study parameters/endpoints: The primary endpoints are: - Clinical efficacy of neoadjuvant PD-1 blockade in VSCC, measured by objective change in tumour size (according to RECIST1.1) - The activation, proliferation and migration of the CD4+CD39+PD-1+ intratumoral T-cell population.
This study is a single-arm, prospective, phase II trial for patients with metastatic esophageal squamous cell carcinoma (ESCC) who received immunotherapy plus chemotherapy as the first-line treatment. The aim of the study is to determine if intervening with combined local therapy and immunotherapy and chemotherapy in patients with ESCC led to significant improvements in survival and disease control compared with historical data.
The purpose of this study is to observe and evaluate the correlation between ctDNA-MRD and the therapeutic effect and prognosis of stage II-IVA operable esophageal squamous cell carcinoma.
This is an open-label, single-dose, prospective clinical trial. The study comprises 2 work packages. The main objective of work package I (WP-1) is to assess feasibility of Fluorescence imaing (FLI) during total laryngectomy (TLE) and to assess the optimal dose of the cRGD-ZW800-1. Work package II (WP-II) is designed to assess whether FLI can detect and decrease tumor positive margins after a TLE.
The objective of this study is to compare the efficacy and safety of MRG003 versus cetuximab/methotrexate as second/third line of therapy in patients with RM-SCCHN who have previously failed PD-1 (L1) inhibitors and platinum-based therapy.
