Filter by:Colorectal cancer (CRC) is a significant cause of morbidity and mortality worldwide. Its early clinical manifestations are often subtle, leading to late-stage diagnosis in about 30% of cases with distant metastases. Liver metastases are widespread and associated with poor prognosis, especially in terms of response to immunotherapy. Despite advancements in first- and second-line treatments, third-line therapies for advanced CRC remain limited, emphasizing the need for novel strategies. This prospective study evaluates the efficacy of combined therapy involving Sintilimab, Fruquintinib/Regorafenib, and radiotherapy in advanced CRC. The study cohort comprises patients with non-liver metastatic advanced CRC and those with liver metastases, each receiving tailored treatment protocols. The primary objectives are to assess progression-free survival (PFS), overall survival (OS), and treatment response rates. Subgroup analyses will focus on liver metastases to delineate their impact on treatment outcomes. The rationale for this study stems from the intricate interplay between immunotherapy, targeted therapy, and radiotherapy in CRC management. Previous data suggest a negative correlation between liver metastases and immunotherapy efficacy, necessitating a comprehensive approach integrating multiple treatment modalities. Radiotherapy, particularly stereotactic body radiation therapy (SBRT), has shown promise in controlling liver tumors and modulating the tumor microenvironment, potentially enhancing immunotherapy responses. This study aims to provide valuable insights into optimizing third-line and subsequent therapies for advanced CRC by elucidating the efficacy and safety of this combined treatment approach. The findings may pave the way for personalized treatment strategies tailored to individual patient characteristics, ultimately improving clinical outcomes in this challenging disease setting.
In the IMRT era, patients with stage II-III (AJCC8th) nasopharyngeal carcinoma achieve high local control. However, survivors are increasingly experiencing late radiation-induced toxicities. A previous study found that reducing the radiation dose to the primary site to 60Gy for patients who achieved partial or complete response to induction chemotherapy resulted in a lower rate of late toxicities and an inferior local control rate. The investigators aim to reduce the radiation dose to the primary site for patients after immunochemotherapy, given the potential of neoadjuvant chemotherapy and immunotherapy to increase response rates and long-term survival. The protocol includes participants with stage II-III (AJCC8th), except T2N0M0, to receive three courses of neoadjuvant gemcitabine plus cisplatin and Toripalimab. If the primary tumour regresses by over 75%, de-escalated radiotherapy with 60Gy will be administered, and participants will receive two cycles of cisplatin and three cycles of Toripalimab during the radiotherapy course. Otherwise, participants will receive conventional radiotherapy and concurrent chemotherapy with cisplatin for two cycles as usual. The aim of this study is to investigate the 3-year local control rate and toxicities of de-escalated radiotherapy.
Solid tumors pose significant challenges in current therapeutic approaches. Targeted therapy has emerged as a promising avenue, aiming to enhance treatment efficacy while minimizing adverse effects. This clinical trial focuses on an innovative combination of two targeted inhibitors, Palbociclib and Bevacizumab, for their potential synergistic effects in addressing these challenging malignancies. Moreover, this study incorporates a molecular approach by considering Long Non-Coding RNAs (LncRNAs) as biomarkers. Initiating with a focus on colorectal cancer, the study aims to expand its scope to other solid tumors, including lung, breast, ovarian and other cancers. Palbociclib, a cyclin-dependent kinase 4/6 (CDK4/6) inhibitor, disrupts the cell cycle progression, particularly in cancer cells with specific molecular characteristics. Bevacizumab, a vascular endothelial growth factor (VEGF) inhibitor, targets angiogenesis-a critical process for tumor growth and metastasis. The rationale behind combining these agents lies in their complementary mechanisms of action, potentially leading to enhanced antitumor effects. LncRNAs have shown promise in predicting treatment response and prognosis in various cancers, providing an additional layer of precision to the treatment strategy. By elucidating the molecular basis through LncRNA analysis, the trial aims to tailor the treatment to the specific molecular profile of each patient, ultimately striving for better outcomes and improved survival rates. This novel combination therapy, coupled with a personalized biomarker-driven approach, represents a cutting-edge strategy in the pursuit of more effective and individualized treatment for solid tumors.
A total of 17 to 23 participants are anticipated to be enrolled in the Phase I clinical trial, which is further divided into two distinct parts: one part involves single-agent cell therapy, while the other entails a combination of cell therapy and Serplulimab Injection. To be more precise, the study aims to include patients who have been diagnosed with metastatic or locally advanced refractory/recurrent malignant solid tumors and have shown resistance to standard therapeutic interventions. These tumor types may encompass head and neck cancer, ovarian cancer, lung cancer, melanoma, and others.
Immune checkpoint inhibitors have ushered in a new era of cancer treatment, bringing significant survival benefits to patients. However, some patients have accelerated tumor growth in the early stage of immunotherapy, called hyperprogression. The quality of life of patients with hyperprogression is seriously reduced, and there is no effective treatment at present, and the prognosis is extremely poor. Therefore, early identification of high-risk groups of hyperprogression is the key to prevent hyperprogression. However, there are no effective biomarkers to predict hyperprogression. By sequencing, proteomics and metabolomics analysis of clinical tissue and blood samples, we found that the level of SAA1 was significantly increased in patients with hyperprogression, and SAA1 was an effective marker for predicting hyperprogression in pan-cancer. We planned to conduct a multicenter, prospective cohort study to verify the reliability of SAA1 as a marker for predicting hyperprogression of immunotherapy in pan-cancer patients.
According to the cancer statistics in 2020, colorectal cancer (CRC) remains a major public health issue worldwide, representing the third common cancer (10%) and second leading cause of death (9.4%) with 5-year survival rate approaching 65%. Meanwhile, 28.8% of the newly diagnosed cases and 30.3% of the CRC-related death occurs in China. Among all the CRC, stage I-III account for 75%. For the standard management for non-late stage(stage I-III) CRC patients, surgery including the primary site and local lymph nodes dissection has been the most important one. But for the high-risk stage II and locally-advanced stage III CRC, neoadjuvant or adjuvant therapy such as chemotherapy and radiotherapy plays a vital role in preventing the residual cancer cells to relapse and spread to distant sites after surgery. For the past decades, immunotherapy like anti-PD-1 and anti-CTLA4 checkpoint inhibitor achieves great process in solid tumor treatment especially for late-stage CRC. And Pembrolizumab and Nivolumab has been proved for dMMR/MSI-H late-stage-CRC by FDA. Combination of Ipilimumab and Nivolumab has achieved great success among the early-stage-CRC in NICHE study. The investigators here to carry out a phase II clinical trial to explore the safety and effect of single anti-PD-1 (Tisleizumab-BGB-A317 ) neoadjuvant treatment for non-late stage CRC patients.
Cervical cancer constitutes a significant health burden for women globally. While most patients with early-stage disease can be cured with radical surgery or chemoradiotherapy, patients with high-risk locally advanced disease or with recurrent/metastatic disease have a poor prognosis with standard treatments. Immunotherapies are a rational treatment for this HPV-driven cancer that commonly expresses programmed cell death ligand-1. Toripalimab, a humanized immunoglobulin G4 monoclonal antibody against PD-1, showed promising anti-tumor efficacy in multiple solid tumors. This randomised study is evaluating toripalimab combined with CCRT versus CCRT alone for treatment-naïve LACC.
This study aims to evaluate the efficacy and safety of neoadjuvant camrelizumab combined with chemotherapy in resectable stage IIIA and IIIB (T3-4N2) non-small cell lung cancer (NSCLC) patients. Inclusion criteria are: age 18-75, pathologically confirmed resectable stage IIIA-IIIB (T3-4N2) NSCLC, absence of EGFR, ALK, and ROS1 gene mutations, and Eastern Cooperative Oncology Group (ECOG) status 0-1. All patients receive three cycles of camrelizumab combined with platinum-based doublet chemotherapy, followed by curative surgery within 4-6 weeks after completion of chemotherapy. Patients undergo 18F-fluorodeoxyglucose (FDG) PET/CT scans in 1 week before treatment and 1 week before surgery, and peripheral blood samples are collected for biomarker analysis. The primary endpoints for follow-up are pathologic complete response (pCR) rate and major pathological response (MPR) rate, while secondary endpoints include safety and progression-free survival. Exploratory endpoints include molecular imaging research and biomarker analysis.
This study is an observational real-world research conducted on Chinese hepatocellular carcinoma (HCC) patients. Its primary objective is to evaluate the safety and efficacy of immunotherapy-based combination therapies in Chinese HCC patients within the practical context of real-world conditions.
At present, the treatment methods for recurrent cervical cancer are very limited. The immune checkpoint inhibitors (ICBs) is a promising new directions for recurrent cervical cancer, but the clinical response rate is insufficient. Pulse low-dose rate radiotherapy (PLDR) is a new technology in recent years, which uses continuous pulse low-dose rate irradiation to induce hypersensitivity in tumors, and its clinical safety has been verified. Compared to conventional radiotherapy, PLDR has advantages in protecting the lymphatic system and relieving the immune barrier, but it is still unclear whether it can improve the efficacy of ICB. This project aims to combine PLDR with ICB to explore new strategies for recurrent cervical cancer.
