Active clinical trials for "Nasopharyngeal Carcinoma"

This prospective trial aims to enroll patients with high-risk stage III-IVA (AJCC 8th, except T3N0) locoregionally-advanced nasopharyngeal carcinoma (LANPC). Under the condition of full course of PD-1/PD-L1 blockades, patients who achieved both radiological and biological complete response after 3 cycles of platinum-based chemotherapy plus PD-1/PD-L1 blockades will be randomized in a 1:1:1 ratio to receive reduced-dose radiotherapy (60Gy/30F) alone or reduced-dose radiotherapy plus concurrent chemotherapy or standard dose radiotherapy (70Gy/33F) with concurrent chemotherapy. To solve the urgent problem of whether patients with high-risk advanced nasopharyngeal carcinoma are suitable for downgrade treatment.

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 trial is aimed to investigate whether additional adjuvant PD-1 antibody treatment could improve survival in high-risk nasopharyngeal carcinoma compared to metronomic capecitabine alone.

A Prospective, Single-arm, Multicenter Clinical Study of Transnasal Endoscopic Surgery Combined With Adjuvant Immunotherapy for Recurrent Nasopharyngeal Carcinoma

The goal of this multicenter randomized non-inferior study is to compare the additon of camrelizumab or nimotuzumab to neoadjuvant chemotherapy followed by concurrent chemoradiotherapy in locally advanced nasopharyngeal carcinoma patients whose EBV DNA remained detectable after one cycle neoadjuvant chemotherapy using GP regimen. The main question it aims to answer is: whether the addition of carrilizumab or nituzumab improve the treatment outcomes in the relatively poor prognostic patients identified by the response of EBV DNA. Participants will be randomized to the combination of carrilizumab and standard treatment , the combination of nituzumab and standard treatment or the standard treatment alone if their EBV DNA didn't decrease to undetectable level post first cycle of neoadjuvant chemotherapy.

The goal of this clinical trial is to compare overall response rate between gemcitabine, nimotuzumab and toripalimab as induction treatment and gemcitabine combined with cisplatine in paitents with locally advanced nasopharyngeal carcinoma. It aims to answer whether gemcitabine, nimotuzumab and toripalimab as induction treatment show non-inferiority compared to GP induction chemotherapy. Participants will be randomly divided into two induction treatment groups.

The goal of this multicenter randomized non-inferior study is to compare radiotherapy alone versus concurrent chemoradiotherapy in locally advanced nasopharyngeal carcinoma patients whose EBV DNA drop to undetectable level after one cycle neoadjuvant chemotherapy using GP regimen. The main question it aims to answer is: the omission of concurrent chemotherapy is safe in the relatively good prognostic patients identified by the response of EBV DNA. Participants will be randomized to either radiotherapy alone or the standard treatment concurrent chemoradiotherapy if their EBV DNA decrease to undetectable level post first cycle of neoadjuvant chemotherapy and don't rebound in the second and third cycle.

This trial is a multi-center phase III clinical trial. The purpose of this trial is to explore whether 2 cycles induction chemotherapy combined with concurrent chemoradiotherapy is not inferior to 3 cycles induction chemotherapy combined with concurrent chemoradiotherapy in patients with locally advanced nasopharyngeal carcinoma.

This study aims at exploring whether plasma radiofrequency ablation at low temperature is associated with better survival outcome in localized recurrent nasopharyngeal carcinoma by conducting a randomized controlled trial of plasma radiofrequency ablation at low temperature versus electrocautery block resection at high frequency for localized recurrent nasopharyngeal carcinoma. If the hypothesis is confirmed, it is expected to provide a convenient choice for the surgical treatment of localized recurrent nasopharyngeal carcinoma.
