Active clinical trials for "Nasopharyngeal Carcinoma"

PCR-DNA of EBV test is a good prognostic indicator for survival after treatment (report: Prognostic Impact of Plasma, Epstein-Barr Virus DNA in Patients with Nasopharyngeal Carcinoma Treated using Intensity-Modulated Radiation Therapy. The chances of the local recurrence or metastasis are higher in the patients at same stage with positive PCR-DNA of EBV in Nasopharyngeal carcinoma after same treatment.(ref.) Antiviral drugs have been used to inhibit EBV replication and target viral DNA polymerase are Foscarnet and phosphonoacetic acid both interact directly with the pyrophosphate-binding site of the enzyme, where Acyclovir as antiviral drug act at two levels: as competitive alternative substrates, competing with GTP on the substrate-binding site, and as DNA chain terminators, by incorporating into the growing DNA chain and blocking its elongation due to their acyclic structure.

Patients will be treated with pembrolizumab after concurrent chemoradiotherapy with cisplatin. Patients will be treated with up to 17 cycles (approximately 1 year) of pembrolizumab until disease progression or recurrence

Up to now, IMRT has largely improved the local control of locally advanced nasopharyngeal carcinoma (NPC), leaves the distant metastasis as the main treatment failure modality of patients with bulky lymph nodes (especially N3 stage). Although concurrent chemoradiotherapy (CCRT) continues to stand as the standard treatment of these patients, the role of adjuvant chemotherapy remains controversial due to its relatively severe toxicities and inferior compliance. However, our retrospective study of 2D-RT and IMRT era had proved adjuvant chemotherapy played key role in N3 NPC patients in terms of reducing distant metastasis and improving overall survival. Maintenance chemotherapy of gemicitabine single drug is promising with adequate efficacy and moderate toxicities. So we aim to conduct "A Phase III Randomized Trial of Maintenance Chemotherapy in High-metastatic Risk Nasopharyngeal Carcinoma Patients of N3 Stage" to evaluate the effectiveness and compliance of gemicitabine as maintenance chemotherapy in N3 nasopharyngeal carcinoma.

Nasopharyngeal carcinoma (NPC) is commonly observed in southern China, particularly in the Pearl River delta area and the Xijiang River basin in the Guangdong and Guangxi provinces, with an incidence rate as high as 25-50 per 100,000. The National Comprehensive Cancer Network guidelines (version 1, 2018), have recommended use of induction chemotherapy followed by CCRT as category 2A for NPC, especially the TPF regimen as category 1 for EBV-associated disease. The nanoparticle albumin-bound paclitaxel (Nab-paclitaxel) is a promising new agent with more efficient entry to the tumor microenvironment and preferential uptake by cancer cells. Superior activity of Nab-paclitaxel regimens without the necessity for antianaphylactic pretreatments has been shown in various solid tumors compared with the traditional solvent-based paclitaxel-based ones. However, the safety and efficacy of combination of Nab-paclitaxel, cisplatin and Fluorouracil (APF) has not been determined in patients with locoregionally advanced NPC. In this prospective, Multi-centeric, Open, Non-controlled phase II clinical trial, investigators perform an exploratory study to the efficacy and Safety of APF.

The purpose of this study is to compare the toxicity and therapeutic efficacy of proton or photon combined with carbon ion radiotherapy for newly diagnosed nasopharyngeal carcinoma.Participants will be randomized to 2 arms. Arm 1, participants received photon combined with carbon ion radiotherapy group, Arm 2, participants received proton combined with carbon ion radiotherapy.

The purpose of this study is to explore the efficacy and safety of combination of Apatinib and Camrelizumab regimen in treating recurrent or metastatic nasopharyngeal carcinoma patients who were resistant to PD-1 antagonists.

This is a study to evaluate the efficacy and safety of TQB2450 injection combination with Intensity-modulated Radiotherapy in patients with inoperable locally recurrent nasopharyngeal carcinoma.

The primary purpose of this study is to explore the significance of analgesic treatment for radiation-induced oral mucositis pain in patients with nasopharyngeal carcinoma during radiotherapy, and to compare the analgesic effect of morphine controlled-release tablets with that of fentanyl transdermal patch. Half of participants will receive morphine controlled-release tablets,while the other half will receive fentanyl transdermal patch.

The purpose of this study is to examine the efficacy of maintenance chemotherapy for the treatment of metastatic nasopharyngeal carcinoma. Participants will be randomized to 3 arms. Arm 1, control group, participants will receive only 4-8 cycles of conventional chemotherapy; arm 2, participants will receive 6 cycles of maintenance chemotherapy after conventional chemotherapy; arm 3, experiment arm, after conventional chemotherapy, participants will receive maintenance chemotherapy until disease progression or intolerable toxicities.

This is a Phase II trial to study the effectiveness of two cycles versus three cycles of Concurrent Chemoradiotherapy in treating patients with Low Risk Locoregionally Advanced Nasopharyngeal Carcinoma based on pretreatment plasma EBV DNA.
