Filter by:This is a single-center, single-arm, open-label study that includes patients meeting the inclusion criteria (liver-GTV volume < 700ml or estimated liver-GTV V5 < 300ml) with hepatocellular carcinoma with diffuse tumor thrombosis involving both left and right lobes. All lesions receive moderate-dose hypofractionated intensity-modulated radiotherapy, with a gross tumor dose of 25Gy/5f, and a maximum dose of 35Gy/5f at the tumor center. One week before or during the radiotherapy, patients receive concurrent Pembrolizumab at a dose of 200mg. Subsequently, Pembrolizumab is administered intravenously every 3 weeks. Follow-up examinations are conducted 1-3 months post-radiotherapy. Lenvatinib 4mg may be used for maintenance therapy with Pembrolizumab if there are no contraindications. Maintenance therapy is continued until disease progression or intolerance. The primary endpoint is median overall survival (mOS), and secondary endpoints include objective response rate (ORR), progression-free survival (PFS), and toxicity.
This study is a prospective, open-label, multi-center phase III study; patients with untreated stage IIIA to stage IVB head and neck squamous cell carcinoma (including oral cavity cancer, oropharyngeal cancer, hypopharyngeal cancer, and laryngeal cancer) who meet the inclusion criteria are randomized 1:1 and given pembrolizumab 200 mg d1+ chemotherapy for 2 cycles (experimental group), 2 cycles of chemotherapy (control group), and then stratified according to the patient's condition. If the imaging evaluation after neoadjuvant treatment is (complete response, CR), adjuvant radiotherapy will be given; if the imaging evaluation is (partial response, PR) or (stable disease, SD), surgery (within 2 weeks) will be performed, followed by standard treatment. The main research hypothesis of this study: pembrolizumab combined with standard chemotherapy can significantly improve the rate of pathological complete response (pCR) compared with standard chemotherapy.
It analyzes the Tumor microenvironment(TME) changes in non pathologic complete response(pCR) subjects among subjects who were administered neoadjuvant pembrolizumab and those who were not administered neoadjuvant pembrolizumab for triple negative breast cancer. (Neoadjuvant Weekly paclitaxel, Carboplatin +- Pembrolizumab followed by Doxorubicin, Cyclophosphamide +- Pembrolizumab regimen)
This is a phase 2, Simon's 2-stage designed study with 2 cohorts of anti-PD-1/PD-L1 experienced patients with untreated brain metastases: 1) melanoma and 2) renal cell carcinoma (RCC).
The purpose of this study is to observe and evaluate the efficacy and safety of postoperative adjuvant treatment of pembrolizumab in patients with thoracic esophageal squamous cell carcinoma （ESCC） who have not received neoadjuvant therapy before undergoing R0 resection, and have positive postoperative lymph nodes.
The purpose of this study is to observe and evaluate the efficacy and safety of pembrolizumab plus cisplatin and 5-fluorouracil (5-FU) followed Surgery for locally advanced adenocarcinoma of esophagogastric junction
This study is a randomized, national multicenter clinical study ，which is designed to compare the efficacy of the safety and efficacy of treatment every 3 weeks or 6 weeks in (Non-small-cell-cell cancer, NSCLC) subjects without systematic treatment， who used Pembrolizumab after 6 cycles of combined chemotherapy， estimated with stable efficacy (CR, PR, and SSD) . In this study, subjects will be randomly assigned to the following two groups according to a 1:1 ratio: (A) Standard maintenance programme group, pembrolizumab 200mg, every 3 weeks, for a total of 2 years of follow-up and follow-up for 1 year; (B) Improvement maintenance programme group, pembrolizumab 200mg, every 6 weeks, for a total of 2 years of follow-up and 1 year follow-up;
