Clinical trials

N3 classification, rENE positivity is a high-risk type of locally advanced nasopharyngeal carcinoma. EBV DNA remaining at detectable levels after induction chemotherapy is also a characteristic of high-risk nasopharyngeal carcinoma. Based on the available evidence, patients with high-risk nasopharyngeal carcinoma are recommended to receive oral maintenance therapy to reduce the risk of failure. The purpose of this study was to conduct a prospective, multicenter, randomized phase III clinical trial to determine whether maintenance therapy with triprilimab combined with capecitabine is better than maintenance therapy with capecitabine alone in high-risk nasopharyngeal carcinoma (N3+, rENE+, Detectable EBV DNA after 2 cycles of induction chemotherapy).

This study investigated the effects of topical chlorhexidine spray on the incidence, severity, and quality of life during radiotherapy in nasopharyngeal carcinoma patients.

This study aims to evaluate the effectiveness and safety of endoscopic nasopharyngeal pseudomembrane removal in reducing radiation-induced nasopharyngeal necrosis in patients with recurrent nasopharyngeal carcinoma who have received re-irradiation. This is a prospective, single-arm, multicenter interventional study. Participants with recurrent nasopharyngeal carcinoma who develop pseudomembrane reaction during or after re-irradiation will receive endoscopic pseudomembrane removal. Based on published literature, the 2-year incidence of radiation-induced nasopharyngeal necrosis after re-irradiation is approximately 40%. This study expects to reduce the incidence to 20%. The primary outcome measure is the 2-year incidence of nasopharyngeal necrosis after re-irradiation. Secondary outcome measures include: necrosis-free survival, overall survival, progression-free survival, local regional recurrence-free survival, distant metastasis-free survival, as well as safety and adverse events. A total of 40 participants will be enrolled from multiple hospitals in China.

Research on radiotherapy target volumes for glioblastoma is increasingly focused on exploring more limited yet effective irradiation fields, aiming to achieve local control while minimizing acute and long-term neurotoxicity. Previous retrospective analysis by investigators revealed that local recurrences of glioblastoma are predominantly confined to a narrow margin around the original lesion: 98.3% of recurrences occurred within 0.5 cm of the original T2-FLAIR abnormality, 94.8% within 1 cm of the original T1-enhanced region. These findings have been cited in the ESTRO-EANO treatment guidelines. Building on this evidence, investigators plan to conduct a single-arm, phase II clinical trial to systematically evaluate the efficacy and safety of a 1 cm radiotherapy target volume in post-operative glioblastoma patients.Eligible patients with glioblastoma who have undergone surgical resection will be selected to receive limited-field radiotherapy. The target volume will be defined based on the postoperative MRI enhancing lesion: a 1 cm margin will be added to form the clinical target volume (CTV), followed by a further 0.3 cm margin to create the planning target volume (PTV). A total dose of 60 Gy will be delivered in 30 fractions (2 Gy per fraction, 5 fractions per week). Concurrent and adjuvant chemotherapy will be administered per standard guidelines. The primary efficacy endpoints are the 6-month progression-free survival rate and the incidence of symptomatic radiation-induced brain necrosis of grade 3 or higher. Secondary endpoints include overall survival, patterns of recurrence, neurocognitive function, and quality of life.

This single-arm, single-center phase II trial evaluates the safety and efficacy of a non-continuous radio-immunotherapy strategy for recurrent nasopharyngeal carcinoma (NPC) unsuitable for surgery. Induction consists of three fractions of low-dose radiotherapy (1.5 Gy ×3) plus high-dose boosts (5 Gy ×3 to tumor core with carotid/mucosal sparing) combined with anti-PD-1 (240 mg IV on Day 1 and Day 22). After a 21-28-day interval, definitive IMRT (2 Gy ×28, 5 days/week) is delivered without concurrent immunotherapy to minimize immune damage. Anti-PD-1 maintenance (240 mg IV Q3W) starts within 2 weeks after radiotherapy for up to 12 months or until progression/toxicity. The primary endpoint is ORR at 3 months post-radiotherapy; secondary endpoints include 3-year OS, 3-year PFS, safety (NCI-CTCAE v5.0), and quality of life (EORTC QLQ-C30). Key eligibility: histologically confirmed non-keratinizing NPC (WHO II/III), rT2-rT4, ECOG 0-1, adequate organ function.

Nasopharyngeal carcinoma (NPC) is a malignant tumor that develops in the nasopharyngeal mucosal epithelium. Due to the disease itself and the impact of anti-tumor therapy, malnutrition has become a common clinical complication in patients with NPC, among which NPC patients receiving concurrent chemoradiotherapy are one of the groups with the highest incidence of malnutrition, and malnutrition seriously affects the prognosis of NPC patients. Nutritional management throughout the course has a positive impact on the prognosis and life management of NPC patients. As an immune-enhancing oral nutritional preparation, it is helpful to maintain the weight and immune function of patients with nasopharyngeal carcinoma during concurrent chemoradiotherapy, reduce the degree of treatment-related side effects during concurrent chemoradiotherapy for nasopharyngeal carcinoma, and delay the occurrence of acute side effects. The purpose of this study was to investigate the effect of rapid rapid rapid improvement of patients' immune status during concurrent chemoradiotherapy, and to further evaluate its impact on patients' weight, prognosis, treatment-related toxic side effects, and quality of life. In this study, 109 patients with nasopharyngeal carcinoma who received concurrent chemoradiotherapy in our hospital are planned to be included, and all patients in this group will be given oral tachyphin at a standard dose from the first day of radiotherapy. The nutritional immune status of the patient was assessed at different points during the treatment period.

This study is a multicenter, non-inferiority, open-label, randomized controlled Phase III clinical trial. It aims to compare the efficacy of modified delineation radiotherapy (experimental group) versus standard delineation radiotherapy (control group) in the prophylactic irradiation of neck lymphatic drainage areas III/IVa in nasopharyngeal carcinoma. The study evaluates the incidence of primary hypothyroidism, quality of life, and adverse events between the two groups.

The purpose of this study is to explore the efficacy and safety of a combination regimen of Anti-PD1 monoclonal antibody, nimotuzumab, and capecitabin in treating recurrent or metastatic nasopharyngeal carcinoma patients who have failed first-line platinum-based chemotherapy.

This study aims to explore the prognostic value of pathological remission after one cycle of induction chemotherapy in locally advanced nasopharyngeal carcinoma, and the change of immune micro-environment after one cycle induction chemotherapy, including the density of immune cells infiltration and tertiary lymphoid structures.

This is an Open, Single Arm, Exploratory and Phase II Clinical Trial of Anlotinib Hydrochloride Capsules Combined With TQB2450 Injection in Esophageal Squamous Cell Carcinoma (ESCC) Patients as Postoperative Adjuvant Therapy. In order to observe and evaluate the efficacy and safety of Anlotinib Hydrochloride Capsules combined with TQB2450 Injection in treatment of patients with ESCC. The primary endpoint is disease free survival (DFS).
