Filter by:This is a multicentre open-label non-randomised, Single Stage Ahern Design (with a 3+3 design for the safety run-in) phase II clinical trial of DKN-01 plus atezolizumab in patients with advanced unresectable or metastatic OGA who have progressed following chemotherapy.
Gastric cancer is a global health issue as the world's fifth most common malignancy and third leading cause of cancer mortality, respectively. Preoperative radiation therapy may improve overall survival (OS) but is seldom used. There is precedent for preoperative chemoradiation, as it is the standard of care for esophageal and gastroesophageal junction tumors. However, reluctance of physicians to prescribe preoperative radiation therapy in gastric cancer may be due to the large treatment fields necessary to account for stomach motion. Adaptive radiation therapy may permit decreased field sizes and more accurate dose delivery. In traditional CT based radiation delivery the same radiation plan is delivered each day without assessment of inter-fraction or intra-fraction motion. Adaptive radiation therapy permits the physician to contour the unique anatomy daily to generate a new plan to account for day to day organ motion. Real-time MR imaging is also used during the treatment so that radiation is only delivered when the tumor is within the pre-specified target area. Thus, adaptive radiation therapy may overcome traditional barriers of radiation delivery in gastric cancer and improve oncologic outcomes.
To evaluate the efficacy and safety of Camrelizumab in Combination With Docetaxel +S-1 Sequenced by Camrelizumab+S-1 as Adjuvant Treatment Therapy in Stage III Gastric Cancer (PD-L1 + / MSI-H / EBV +/dMMR) . Secondary study objective: To observe and evaluate the overall survival and adverse events of Camrelizumab in Combination With Docetaxel +S-1 Sequenced by Camrelizumab+S-1 as Adjuvant Treatment Therapy in Stage III Gastric Cancer (PD-L1 + / MSI-H / EBV +/dMMR). To evaluate the safety ofCamrelizumab in Combination With Docetaxel +S-1 Sequenced by Camrelizumab+S-1 as Adjuvant Treatment Therapy in Stage III Gastric Cancer (PD-L1 + / MSI-H / EBV +/dMMR). Objective: To explore the incidence of PD-L1 + / MSI-H / EBV + /dMMR in stage III gastric cancer. To explore the correlation of PD-L1 + / MSI-H / EBV + /dMMR in stage III gastric cancer.
The purpose of the study is to determine to evaluate safety and tolerability of CPL304110 when administered once daily to adults with advanced solid malignancies.
This phase I trial studies a new imaging technique called FAPi PET/CT to determine where and to which degree the FAPI tracer (68Ga-FAPi-46) accumulate in normal and cancer tissues in patients with non-prostate cancer. The research team also want to know whether what they see on PET/CT images represents the tumor tissue being excised from the patient's body. The research team is also interested to investigate another new imaging technique called PSMA PET/CT. Participants will be invited to undergo another PET/CT scan, with the PSMA tracer (68Ga-PSMA-11). This is not required but just an option for volunteer patients. Patients who have not received an 18F-FDG PET/CT within one month of enrollment will also undergo an FDG PET/CT scan. The PET/CT scanner combines the PET and the CT scanners into a single device. This device combines the anatomic (body structure) information provided by the CT scan with the metabolic information obtained from the PET scan. PET is an established imaging technique that utilizes small amounts of radioactivity attached to very minimal amounts of, in the case of this research, 68Ga-PSMA-11 and 68Ga-FAPi, and 18F-FDG (if applicable). Because some cancers take up 68Ga-PSMA-11 and/or 68Ga-FAPi it can be seen with PET. CT utilizes x-rays that traverse the body from the outside. CT images provide an exact outline of organs where it occurs in patient's body. FAP stands for Fibroblast Activation Protein. FAP is produced by cells that surround tumors. The function of FAP is not well understood but imaging studies have shown that FAP can be detected with FAPI PET/CT. Imaging FAP with FAPI PET/CT may in the future provide additional information about various cancers. PSMA stands for Prostate Specific Membrane Antigen. This name is incorrect as PSMA is also found in many other cancers. The function of PSMA is not well understood but imaging studies have shown that PSMA can be detected with PET in many non-prostate cancers. Imaging FAP with PET/CT may in the future provide additional information about various cancers.
This is a two-arm, randomized, double-blinded, multicenter phase III clinical study to evaluate the efficacy of HLX10 combined with chemotherapy versus placebo combined with chemotherapy for neoadjuvant/adjuvant treatment of gastric cancer. Subjects will be randomized to the following two arms at 1: 1 ratio: - Arm A (HLX10 arm): HLX10 combined with chemotherapy will be adopted in the neoadjuvant treatment phase, and HLX10 monotherapy will be administered in the adjuvant treatment phase; - Arm B (control arm): Placebo combined with chemotherapy will be given in the neoadjuvant treatment phase, and chemotherapy alone will be administered during the adjuvant treatment phase. Chemotherapy regimen SOX (oxaliplatin + tegafor gimeracil oteracil potassium (S-1)) will be used in the neoadjuvant treatment phase in Arm A and B, and in the adjuvant treatment phase in Arm B. After randomization, subjects will receive a total of 3 cycles of neoadjuvant treatment with the mentioned treatment regimen.Surgery will be performed within 3-6 weeks after the last cycle of neoadjuvant treatment.All subjects who have completed the surgery will be unblinded after surgery, and adjuvant treatment will be started 3 to 12 weeks after surgery. Subjects randomized to Arm A (HLX10 arm) will continue to receive HLX10 monotherapy for up to 17 cycles (12 months).Subjects in Arm B after surgery (control arm) will continue to use chemotherapy alone (oxaliplatin + S-1) for 5 cycles.
This is an explorative, phase I clinical trial. The aim of this study is to establish the safety and efficacy of electrochemotherapy for non-curable gastric cancer.
This study is intended to evaluate efficacy and safety of EGFR monoclonal antibody (Cetuximab/Nimotuzumab) in combination with a chemotherapy in gastric cancer patients with EGFR amplification.
This is a randomized, open-label phase III study. The treatment was compare the efficacy and safety of Albumin-bound Paclitaxel plus S-1 versus Oxaliplatin plus capecitabine (XELOX) treating stage Ⅲ gastric cancer as adjuvant setting
Gastric cancer (GC) is one of the most common malignancies. According to the global cancer statistics 2018, there were 1,033,701 new cases of gastric cancer per year, ranked the fifth place in new tumors, and 782,685 deaths, ranked the second place in cancer deaths. At present, surgery is the only way to cure gastric cancer, but the 5-year survival rate is only 20%-30%. studies have confirmed that neoadjuvant therapy could improve the R0 resection rate and overall survival, which is considered a better treatment strategy. PD 1 monoclonal antibody is definitely effective in neoadjuvant therapy in other tumors such as NSCLC and bladder cancer, especially in PD-L1+ patients. However, there is no research of PD-1 monoclonal antibody in neoadjuvant therapy of gastric cancer. Thus we plan to conduct this prospective phase II clinical trial, evaluating the safety and efficacy of toripalimab, also known as JS001, in combination with XELOX for the neoadjuvant therapy of gastric cancer.
