Filter by:A Phase II Trial of S-1 as Maintenance Treatment After Gemcitabine Plus Cisplatin Regimen Chemotherapy in Patients With Recurrent and/or Metastatic Nasopharyngeal Carcinoma.
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.
The purpose of this study is to determine the maximal tolerated dose (MTD) of re-irradiation using carbon ion radiotherapy (CIRT) along with concurrent chemotherapy in the treatment of locally recurrent nasopharyngeal cancer (NPC) and to evaluate the efficacy of such treatment at the MTD. Participants will be treated with CIRT with escalating dose regimens along with concurrent chemotherapy (40 mg/m^2, weekly) to evaluate the maximal tolerated dose (MTD) in terms of acute and subactue toxicity observed during and within 4 months after the completion of concurrent chemoradiotherapy. Once the MTD for locally recurrent NPC is determined, the MTD will be used as the recommended dose to patients fulfilling the inclusion criteria in the Phase II part of the trial.
Nasopharyngeal carcinoma (NPC) is an Epstein-Barr virus(EBV) related malignancy and is an endemic disease in Southeast Asian countries. EBV had been identified as a therapeutic target in some EBV related cancer such as lymphoma and NPC. In cancer cell, EBV was in latent phase and expressed 8-11 genes for maintaining EBV proliferation. After switching to lytic phase, almost all the EBV encoding genes were expressed including thymidine kinase (TK) and some highly immunogenetic genes. These latent-lytic phase swifter included DNA methyltransferase inhibitors, various histone deacetylase (HDAC) inhibitors, radiotherapy and chemotherapy. Recently, combined chemotherapy and viral lytic therapy, cytolytic viral activation therapy (CVAT) had been shown some promising result in pilot study of NPC. In our patient derived xenograft (PDX) animal model drug sensitivity screening, gemcitabine (GEM) was shown to be the most effective drug. Furthermore, CVAT with GEM + Valproic acid (VPA) + ganciclovir (GCV) maintaining chemotherapy may benefit but reduce chemotherapy related side effect and prolonging treatment response duration. The following phase I clinical trial will be proposed to test the optimal combination of these drugs. 1. Number of patients: total 18 patients are needed 2. Inclusion criteria:(1) used as 2nd line regimen in recurrence/metastasis NPC patients with tissue proved of World Health Organization (WHO) type II or type III.(2) Performance status: eastern cooperative oncology group performance status (ECOG PS) ≤2. 3. Chemotherapy regimen: Gemcitabine (GEM, TTY) + Valproic acid (VPA, generic medicine) for viral activation + Valganciclovir (VGC, Roche) for antiviral medication 4. This treatment cycle of 28 days was repeated maximum 6 times. (Q4wks/cycle, max: 6 cycles) 5. Dosage: (1) GEM: 600, 800, 1000, 1250 mg/m^2, D1 & D8, intravenously. (2) VPA 12.5 mg/kg/day D1~14, per os. (3) VGC (2-3) x 450 mg/day D9~15, per os. 6. Objectives: 1. primary: to find the best combination of these 3 drugs in recurrent/metastatic NPC patients. 2. second: to evaluate the response and disease control rate in this pilot study. Key words: NPC, cytolytic viral activation therapy, gemcitabine, valproic acid, ganciclovir.
Currently, concurrent chemoradiotherapy with/without sequential chemotherapy is the standard treatment modality for intermediate risk NPC (stage II and T3N0M0) according to the National Comprehensive Cancer Network guideline. However these recommendations were based on the evidence in the two-dimensional conventional radiotherapy (2DCRT) era. The introduction of intensity-modulated radiotherapy (IMRT) in NPC treatment has brought substantial better treatment outcomes than 2DCRT. It has been questioned whether additional concurrent chemotherapy is still necessary for intermediate risk NPC within the excellent framework of IMRT. Thus, the investigators jointly conduct the first non-inferior randomized trial to determine the value of concurrent chemotherapy with cisplatin for intermediate risk NPC patients treated with IMRT. Given the results of clinical studies mentioned above,the investigators decide to adopt the concurrent regimen to be cisplatin 100 mg/m2 on day 1, 22, 43
This is a Phase Ⅲ randomized, controlled, multi-center, trial comparing cisplatin plus docetaxel to cetuximab, cisplatin, and docetaxel induction chemotherapy followed by concurrent chemoradiation in previously untreated patients metastatic nasopharyngeal carcinoma (mNPC) to determine whether the addition of cetuximab to induction chemotherapy and chemoradiation could improve therapeutic efficacy in mNPC, and investigate predictive and prognostic factors for mNPC.
The investigators aim to evaluate the efficiency and toxicities of concurrent docetaxel and cisplatin with intensity-modulated radiotherapy in high risk locoregionally advanced nasopharyngeal carcinoma.
A prior phase III randomized trial showed considerable survival benefit from the combined treatment of cisplatin-based concurrent chemotherapy and two-dimensional conventional radiotherapy (2DCRT) for patients with stage II (the Chinese 1992 staging system) nasopharyngeal carcinoma. However, since intensity-modulated radiotherapy (IMRT) was known to be superior to 2DCRT in local control, progression free survival and even overall survival, it is a pivotal question whether stage II [T1N1M0 and T2N0-1M0, based on the 2010 International Union against Cancer/American Joint Committee on Cancer (UICC/AJCC) staging system] patients can still obtain significant benefit from the additional concurrent chemotherapy in the IMRT era. The investigators' retrospective study (PMID:26528755 ) indicated that low risk nasopharyngeal carcinoma (T1N1M0, T2N0-1M0 or T3N0M0, the 2010 UICC/AJCC staging system) patients who underwent IMRT could not benefit from cisplatin-based concurrent chemotherapy. Therefore, the investigators perform this randomized controlled trial to address this question, on a prudent assumption that IMRT alone was not inferior to IMRT plus concurrent chemotherapy in stage II patients.
We define refractory nasopharyngeal carcinoma as the following: recurrence with radiation brain injury after radiotherapy, recurrence after the second or more courses of radiotherapy, standard treatment failure after recurrence, and first-line treatment failure after multiple distant metastasis. There is no standard treatment for refractory nasopharyngeal carcinoma. Platinum plus 5-Fu is the classic regimen for primary treatment of nasopharyngeal carcinoma. Endostatin is a multiple targeted angiogenesis inhibitor acting on tumor associated neovascular endothelial cells, normalizing the morphology and function of tumor vasculature, and indirectly leading to the quiescence or reduction of tumors. The purpose of this phase II clinical trial is to determine the efficacy and safety of nedaplatin plus continuous low dose 5-Fu intravenous infusion combined with endostar® (Recombinant Human Endostatin Injection) continuous intravenous infusion compared with nedaplatin plus continuous low dose 5-Fu intravenous infusion alone in refractory nasopharyngeal carcinoma. The study hypothesis is that nedaplatin plus continuous low dose 5-Fu intravenous infusion combined with endostar® continuous intravenous infusion is effective and safe in refractory nasopharyngeal carcinoma.
The purpose of this study is to determine whether celecoxib is effective in the treatment of nasopharyngeal carcinoma by concurrent chemoradiation with weekly nedaplatin.
