Filter by:Nowadays, there are few second-line treatment options for advanced hepatocellular carcinoma (HCC). In order to further improve the efficacy of second-line treatment for advanced HCC, we plan to conduct a single-arm, single-center and phase II clinical study to explore the efficacy and safety of the new second-line treatment for advanced HCC. Previous studies had shown that FOLFOX systemic chemotherapy tended to increase the median survival time of patients with advanced HCC, and significantly improved the progression-free survival and tumor response rate. Therefore, FOLFOX systemic chemotherapy has become one of the recommended treatments for advanced HCC in Chinese guidelines. A phase II clinical study had showed that sintilimab combined with fruquintinib was with a promising anti-tumor activity in patients with advanced HCC who had received standard treatment, with a median progression-free survival of 7.4 months and a tumor response rate of 31.6%. Furthermore, there was a synergistic effect among chemotherapy, immunotherapy and anti-angiogenic therapy. Our previous phase II study showed that the median progression-free survival was 9.73 months, the median overall survival time was 14.63 months, and the tumor response rate was 43.3% in HCC patients extrahepatic metastasis who received FOLFOX systemic chemotherapy combined with targeted and immunotherapy. The results from our study suggested that the combination therapy had excellent anti-tumor efficacy and safety profile. Therefore. We intend to conduct this clinical study to explore the efficacy and safety of FOLFOX systemic chemotherapy combined with fruquintinib and sintilimab in second-line treatment for patients with unresectable HCC after first-line treatment.
Elderly or malnourished patients diagnosed with locally advanced esophageal squamous cell carcinoma (ESCC) 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 with a dose of 800mg per week and S-1 and concurrent radiotherapy for patients who are elderly or malnourished.
Although unprecedented advances have been made in the field of esophageal cancer in recent decades, the prognosis for patients with locally advanced esophageal squamous cell carcinoma (ESCC) remains extremely poor, accounting for 30-40% of overall survival at 5 year. In recent years, multimodal treatments have proven to be an appropriate therapeutic approach for locally advanced ESCC. Recently, immunotherapy developed rapidly. The purpose of this study was to observe the efficacy and safety of cardonilizumab combined with chemoradiotherapy in the treatment of locally advanced ESCC.
This trial is a prospective, randomized, controlled, multicenter, phase II clinical study to evaluate the efficacy and safety of sintilimab as consolidation therapy in elderly patients with esophageal cancer who did not progress after concurrent chemoradiotherapy. Patients aged 70-85 years with esophageal squamous cell carcinoma who did not progress after concurrent chemoradiotherapy and meet the inclusion criteria will be stratified according to MRD status (positive vs negative) and randomized in a 1:1 ratio into two groups: the treatment group receiving sintilimab (for patients with a weight <60 kg: 3 mg/kg IV on Day 1 every 3 weeks; for patients with a weight ≥60 kg: 200 mg IV on Day 1 every 3 weeks) and the observation group receiving regular follow-up. Patients should receive the first dose within 42 days after completing the last radiotherapy session and continue treatment until disease progression, intolerable toxicity, loss to follow-up, death, or other circumstances where the investigator determines treatment should be discontinued, whichever occurs first. The maximum duration of sintilimab treatment is 12 months (from the start of treatment), while the observation group will be followed up every 3 months for at least one year. No other anti-tumor treatments are allowed during the study period. The study aims to compare the effects of the two treatment modalities on progression-free survival, overall survival, tumor response, toxicity reactions, and quality of life in elderly patients with esophageal cancer.
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.
To explore the safety and efficacy of Albumin-Bound Paclitaxel/Platinum based concurrent chemoradiotherapy Followed by PD-1 inhibitor (Sintilimab) in locally advanced cervical cancer
The aim of this study was to develop an radiomic model based on CT images to evaluate markers of the bladder cancer microenvironment, such as TSR,TIL, and IP. Secondly, the association of the radiomic model with clinical outcomes and immunotherapy response was investigated.
To explore the predictive value of immune cells by single-cell sequencing on the outcome of locally advanced cervical cancer treated by concurrent chemoradiotherapy Followed by PD-1 inhibitor
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.
