Active clinical trials for "Nasopharyngeal Carcinoma"

A Phase 1, open label, dose escalation and expanded cohort study of P-MUC1C-ALLO1 in adult subjects with advanced or metastatic epithelial derived solid tumors, including but not limited to the tumor types listed below.

Post radiation nasopharyngeal necrosis is a relatively special radiotherapy sequelae after radiotherapy for nasopharyngeal carcinoma. According to the degree of its development, it can be roughly divided into three stages: mild, moderate and severe stages, corresponding to the pre-nasopharyngeal necrosis stage, the soft tissue necrosis stage and the bone necrosis stage respectively. In the past, treatment methods were limited, including anti-infection, topical nasopharyngeal drugs, etc., the efficacy was not good, the nasopharyngeal necrosis lesions progressed, and a series of serious complications occurred, such as: intracranial infection secondary to osteonecrosis, massive nasopharyngeal hemorrhage, etc. It seriously endanger the life of the patient. With the continuous development of medical technology, the means of treatment are also constantly updated, such as repeated debridement guided by nasal endoscope, modified nasopharyngeal irrigation and hyperbaric oxygen therapy, the healing rate of nasopharyngeal necrosis has improved, especially the cure rate of patients in the mild and moderate-stages can reach 54.1%-54.8%. However, there are still some patients with poor healing of nasopharyngeal wounds after treatment. Since 2004, our team has carried out a series of studies such as transnasal endoscopic nasopharyngeal resection combined with posterior pedicle nasal septum and floor mucoperiosteum flap(NSFF), and successfully achieved minimally invasive and en bloc resection of localized recurrent nasopharyngeal carcinoma. This method basically solved the problem of surgical wound healing of recurrent nasopharyngeal carcinoma. On this basis, we further applied it to the treatment of nasopharyngeal necrosis to further improve the cure rate and improve the prognosis. In addition, our retrospective study showed that compared with conservative treatment, curative-intent endoscopic necrectomy followed by reconstruction using the posterior pedicle nasal septum and floor mucoperiosteum flap can effectively prolong the overall survival time of patients and significantly improve the symptoms, but it still needs to be further confirmed by prospective clinical trials. In addition, some patients (22.2%) had necrosis of the mucosal flap after receiving surgery, which affected the healing of surgical wounds. Besides, the development of nasopharyngeal necrosis is a slow process. If nasopharyngeal necrosis removal combined with pedicled mucosal flap repair is performed prematurely, the area outside the operation area may be necrotic again. Theoretically, each patient only has the nasal septum-nasal septum mucosal flaps on both sides of the nasal septum, which means that each patient only has 2 chances of repairing the nasal septum-nasal floor mucosal flaps. Premature surgical intervention may not only lead to incomplete debridement, but also lose a valuable opportunity for mucosal flap repair. Therefore, based on the above problems, this study intends to compare the endoscopic nasopharyngeal necrosis debridement combined with pedicled mucosal flap repair versus the best conservative regimen for the treatment of early and mid-stage nasopharyngeal necrosis, to explore the prognosis of patients with nasopharyngeal necrosis. The preferred regimen, if confirmed by this study, is expected to standardize the treatment of nasopharyngeal necrosis after radiotherapy and further promote it, effectively increasing the cure rate of nasopharyngeal necrosis and improving the prognosis of patients.

This randomized clinical trial determining whether Sintilimab plus Capecitabine versus Capecitabine alone can improve the progression-free survival rate of NPC patients with unfavorable response to induction chemotherapy. Patients whose plasma EBV DNA> 0 copy/mL or SD/PD according to RECIST1.1 after two cycles induction chemotherapy will have concurrent chemoradiotherapy. MRI, CT and EBV DNA will be assessed before the end of radiotherapy. After concurrent chemoradiotherapy, eligible patients will be randomized to receive either adjuvant Sintilimab plus Capecitabine or Capecitabine alone.

Current radiotherapy guidelines and consensus statements uniformly recommend elective region irradiation (ERI) as the standard strategy for nasopharyngeal carcinoma (NPC). However, given the scarcity of skip-metastasis, the improved assessment accuracy of nodal involvement, and the striking advancements in chemotherapy for NPC, a one-fits-all delineation scheme for clinical target volumes for the nodal region (CTVn) may not be appropriate anymore, and modifications of the CTVn delineation strategy may be warranted. Involved site irradiation (ISI) covering merely the initially involved nodal site and potential extranodal extension has been confirmed to be as effective as ERI with decreased radiation-related toxicities in some malignancies, but has not yet been investigated in NPC. This study aims to compare the regional control, survival outcomes, radiation-related toxicities, and quality of life (QoL) of ISI with conventional ERI in NPC patients with a limited nodal burden.

Nasopharyngeal carcinoma is biologically different from traditional head and neck squamous cell carcinoma. The mainstay treatment for locally advanced nasopharyngeal carcinoma is cisplatin-based concurrent chemoradiation. Recent phase III randomized control trials have demonstrated that induction chemotherapy plus concurrent chemoradiation further improved progression-free survival. However, not every patient has good response to induction chemotherapy. Evidence has accumulated that those with poor response to induction chemotherapy, or those with detectable Epstein-Barr Virus (EBV) DNA post induction chemotherapy, correlated with poorer progression-free survival. Huang CL et al. (Int J Radiat Oncol Bio Phys. 2019) reported that plasma EBV DNA load at completion of induction chemotherapy was an independent and earlier predictor for progression-free survival and overall survival in locally advanced nasopharyngeal carcinoma. Lv J et al. (Nat Commun. 2019) demonstrated that real-time monitoring of plasma EBV DNA response added prognostic information, and had the potential uitility for risk-adapted treatment intensification in nasopharyngeal carcinoma. Therefore, investigators selects those with poor plasma EBV DNA response during and after induction chemotherapy, and intensifies the treatment with combination of anti-PD-1 antibody, in order to improve progression-free survival in locally advanced nasopharyngeal carcinoma, according to response-adapted strategy.

This study aims to explore a new, more effective and tolerable treatment regimen for patients with advanced recurrent/metastatic nasopharyngeal carcinoma. Specifically, we plan to conduct a phase III randomized controlled clinical trial based on the standard treatment of "GP + PD-1 mAb", replacing cisplatin with apatinib to achieve "platinum-free" therapy and reduce toxicity. In addition, we will investigate the efficacy of using apatinib in combination with PD-1 mAb compared to PD-1 mAb monotherapy to further improve treatment outcomes. The ultimate goal is to provide a new and reliable treatment modality for patients with advanced recurrent/metastatic nasopharyngeal carcinoma and guide clinical practice.

Nasopharyngeal carcinoma (NPC) is a head and neck tumor. Studies have shown that more than 70% of patients are diagnosed with locally advanced nasopharyngeal carcinoma at the time of initial diagnosis. The 3-year survival rate of locally advanced nasopharyngeal carcinoma after chemotherapy is over 90%, but 30% of patients still have recurrence and distant metastasis. Therefore, while improving the level of radiation therapy technology, we should study multidisciplinary comprehensive treatment methods and put forward the biological concept of "cure". Induction chemotherapy can effectively create better radiotherapy conditions for locally advanced nasopharyngeal carcinoma, especially for patients with large lesions, improve the treatment response rate, and may reduce the local recurrence and distant metastasis rate. After the end of neoadjuvant chemotherapy, compared with patients who only reached SD, patients who reached CR had a significant survival benefit; Other patients had a reduced rate of distant metastasis, which aroused our interest, although there was no obvious survival benefit. The national multicenter phase II clinical study showed that nitumab combined with radiotherapy significantly improved the 3-year survival rate of patients with locally advanced nasopharyngeal carcinoma compared with radiotherapy alone. According to the previous related research results, nitumab combined with induction chemotherapy or concurrent chemoradiotherapy has a certain effect on nasopharyngeal carcinoma without obvious adverse reactions. However, prospective studies on the short-term efficacy and safety of local advanced nasopharyngeal carcinoma combined with induction chemotherapy and concurrent chemoradiotherapy are still lacking (Taisheng ®）。

Radiotherapy combined with recombinant human endostatin and capecitabine for patients with nasopharyngeal carcinoma (NPC) resistant to induction chemotherapy.

In the era of comprehensive therapy, many studies have investigated the value of induction chemotherapy (IC) in the treatment of nasopharyngeal carcinoma (NPC). Concurrent cisplatin and radiotherapy is the foundation of concurrent chemoradiotherapy strategies, and the addition of cisplatin-based induction chemotherapy to concurrent chemoradiotherapy (CCRT) is considered to prolong survival by reducing distant metastasis in patients with high-risk disease. However, the severity of acute toxicities was significantly increased, which can compromise quality of life and lead to interruptions in CCRT. Fortunately, Locoregional control has substantially improved as the intensity-modulated radiation therapy (IMRT) technique has been widely used in the last decades, IMRT improved the treatment outcomes of patients with NPC, especially the local control rate. Currently, in the era of IMRT, whether patients with NPC benefit from IC plus radiotherapy alone and reduce toxicities compared with IC combined with CCRT. Therefore, the investigators propose this randomized phase III prospective study to assess the efficacy and contribution of IC plus radiotherapy alone in locoregionally advanced NPC during IMRT era.

The purpose of this study is to characterize the safety and tolerability of KFA115 and KFA115 in combination with tislelizumab in patients with select advanced cancers, and to identify the maximum tolerated dose and/or recommended dose.
