Active clinical trials for "Nasopharyngeal Carcinoma"

Researchers conduct the clinical trial (gemcitabine combined with cisplatin induction chemotherapy followed by concurrent chemoradiotherapy with gemcitabine for locally advanced nasopharyngeal carcinoma) to evaluate the safety and effectiveness of gemcitabine in patients with locally advanced nasopharyngeal carcinoma.

The purpose of this study is to explore the efficacy and safety of a combination of GP chemotherapy and tislelizumab in neoadjuvant therapy of locoregionally advanced nasopharyngeal carcinoma patients.

The goal of this clinical trial is to compare efficacy of two different resection extension in patients with resectable recurrent nasopharyngeal carcinoma after induction chemotherapy. The main question it aims to answer is that whether tumor regress areas after induction chemotherapy required complete resection. Patients will be randomly assigned to receive reduced-target resection or full-target resection after induction chemotherapy. Researchers will compare these two groups to see if the efficacy of reduced-target resection is not inferior to full-target resection.

Nimotuzumab is an IgG1 humanized monoclonal antibody that recognized an epitope located in the extra cellular domain of the human epidermal growth factor receptor (EGFR). Nimotuzumab has been granted approval for use in squamous cell carcinoma of head and neck (SCCHN), glioma and nasopharyngeal cancer in different countries. This is a multi-center, randomized controlled trial, with the purpose to evaluate the therapeutic efficacy and safety of nimotuzumab combined with induction chemotherapy plus chemoradiation and adjuvant therapy in locoregionally advanced nasopharyngeal carcinoma.

Because most patients with R/M NPC have received long-term maintenance of immunotherapy at the time of initial treatment and the first-line treatment, there are a large number of PD-1 inhibitor refractory patients. How to deal with the ICIs resistance is an urgent problem in clinical practice.

The goal of this clinical trial is to learn about hepatectomy on the prognosis of patients with nasopharyngeal carcinoma liver metastases (NCLM). The main questions it aims to answer are: To explore the effect of hepatectomy on the overall survival, recurrence-free survival and other prognostic indicators of patients with NCLM. To explore the impact of hepatectomy on the safety of patients with NCLM. Researchers will compare the prognosis of the patients in the hepatectomy group and the patients with NCLM who were prospectively enrolled in the same institution and received only systemic treatment at the same time by propensity score matching.

This is a prospective phase II clinical trial to evaluate the efficacy and safety of Anrotinib and Tirelizumab as a first-line treatment in patients with advanced recurrent or metastatic nasopharyngeal carcinoma.

Through multicenter, open-label, randomised clinical trials, we intend to demonstrate that PD-1 treatment added to salvage surgery could further decrease the rate of disease progression and improve the survival outcome of patients with resectable locally recurrent nasopharyngeal carcinoma compared with those treated with salvage surgery alone.

Recurrence rate after curative treatment for locally advanced Nasopharyngeal carcinoma (NPC) is reported varying from 15% to 30% of cases, while approximately 5-11% of patients present with de novo metastatic disease. In NPC, the immunogenicity of the cancer cell is derived from accumulated somatic mutations, but also from genomic and proteomic differences between host and Epstein Barr Virus (EBV). However, anti-cancer immune response tends to be feeble. This impaired anti-cancer immunity could be attributed to multiple factors including strategies to escape anti-cancer immunity. One of this is switch to immunosuppressive microenvironment, as well as aberrant negative co-stimulatory signals like PD-L1, that is over expressed in NPC. In 2017, the landmark KEYNOTE-028 trial firstly reported promising antitumor activities and safety profiles of pembrolizumab in previously treated RM-NPC Overall, after the treatment of PD-1 inhibitors, about 25% and 60% of the recurrent or metastatic nasopharyngeal carcinoma patients achieved ORR and DCR, respectively, with a profile of toxicities in line with the use of immune checkpoint inhibitors in other diseases. Recently, it was found that some non-BRCA-mutated tumors often harbor other alterations in HR genes except for germline BRCA deleterious mutations, thus making these tumors could benefit from PARPi treatment. PARP could contribute to resistance to chemotherapy induced DNA damage, NPC cell platinum resistant could use PARP to repair and escape apoptosis. In nasopharyngeal carcinoma PARP1 is overexpressed in comparison with normal nasopharyngeal cells, LMP1 (latent membrane protein one) activates PARP1 and increases Poly(ADP-ribos)ylation (PARylation) through PARP1. A preclinical study demonstrates that LMP1+ cells are more sensitive to PARP1 inhibition. After receiving PARPi treatment, accumulated chromosome rearrangements generate plenty of neoantigens and elevate the immunogenicity of tumor, PARPi-mediated acute inflammation remodels tumor immune microenvironment and drives a systemic Th1-skewing immune response. Patients in the POINT trial will receive pembrolizumab 200 mg intravenously (IV) on Day 1 of every 3-week dosing cycle (Q3W) and olaparib 300 mg capsules twice a day (BID) every day starting from Day 1 of Cycle 1. Treatment with protocol therapy will continue until objective disease progression, any prohibitive toxicity or until a maximum of 35 treatment cycles (up to 2 years).

The aim of this study is to compare the efficacy of Toripalimab Combined with GP Regimen Chemotherapy Versus GP Regimen Chemotherapy for Primary Metastatic NPC.
