Active clinical trials for "Nasopharyngeal Neoplasms"

Nasopharyngeal cancer (NPC) is a cancer that starts at the back of the nose. Without distant spread, NPC is sensitive to radiotherapy and chemotherapy; however, if NPC relapses or spreads to other organs, treatment options are limited. This grant proposes to evaluate the safety and tolerability of a novel treatment for patients with NPC that has either relapsed or spread to distant organs. Epstein-Barr Virus (EBV) is known to play a role in the development of NPC, and studies have shown that NPC tumor cells express proteins that are related to EBV. Some of these proteins can trigger a response from the immune system, specifically the activation of cytotoxic T lymphocytes (CTLs), a type of immune cell that might exert anti-tumor effects. In this project, we will take blood from NPC patients, generate CTLs targeted against EBV, and re-infuse these back into patients in an attempt to achieve anti-tumor activity. Patients will also receive an antibody called CD45 Mab prior to CTL infusion in order to allow for better expansion of the infused CTLs in the patients.

This study is to observe and compare the effect of docetaxel plus lobaplatin induction chemotherapy combined with lopoplatin chemoradiotherapy and TPF induction chemotherapy combined with cisplatin chemoradiotherapy on dendritic cells subsets in the treatment of locally advanced head and neck squamous cell carcinoma.

Colorectal cancer (CRC) is a leading cause for cancer related mortality in the western world with a lifetime risk of 6%. Etiology is complex, while genetic background significantly affects the risk. Around one third of all genetic disorders as well as most cases of Familial Adenomatous Polyposis (FAP) and a large proportion of all sporadic CRC cases occur as a result of premature nonsense mutations (creating a stop codon) in an individual's adenomatous polyposis coli (APC) gene. Nonsense mutations are single-point alterations in the DNA that prematurely halt the protein translation process, producing a shortened, nonfunctional protein. In many of these cases, if the cell can be 'persuaded' to ignore the premature stop codon signal, the resulting protein may be able to ameliorate or stop the disease. Recently, members of the aminoglycoside family of antibiotics have been found to induce ribosomal read-through of nonsense mutations, leading to expression of a full length, functional protein. Investigators have recently shown that members of the aminoglycoside and macrolide antibiotic families can induce read-through of the nonsense mutations in the APC gene and lead to reduced oncogenic phenotypes in CRC cells and in different mice models. The aim of this project is to determine the ability of the macrolide antibiotic-erythromycin to induce read-through of the nonsense mutations in the APC gene and to induce expression of a full length, functional APC protein in patients suffering from FAP and to tests its effect on adenoma number and size and on desmoid tumors in these patients. The future goal is to maximize the effect of stop-codon suppressors on APC while minimizing side effects. In this study investigators will select FAP patients which carry APC nonsense mutations, treat them with erythromycin PO for 4-6 months and examine colonic and duodenal adenomas as well as abdominal desmoid tumors, that will be documented before during and after treatment. In parallel, investigators will test polyp, adenoma and desmoid tissue samples as well as blood samples from these patients for changes in expression levels of the APC protein and related oncogenic markers. Suppression of nonsense mutations within the APC gene should be of benefit for patients suffering from FAP, attenuated FAP or multiple adenomas and for patients with advanced or diffuse CRC. Furthermore, given the rapid progress being made in the identification of different nonsense mutations in human genes that lead to mostly un-curable disease, the identification of clinically approved compounds that suppress nonsense mutations and that can be administered long-term without significant side effects would open new venues in the treatment of genetic human diseases that arise from pre-mature stop codons in important coding sequences. Immediate goal: establish the ability of erythromycin to read-through APC nonsense mutation in FAP patients. The read-through effect of erythromycin will be clinically tested by counting and measuring the number and size of both colonic and duodenal adenomas before and over treatment and by measuring the size of known desmoid tumors. Samples of the adenomas and desmoid tumors will be tested by western blot, immunofluorescence and immunohistochemistry for restoration of APC expression and changes in oncogenic markers. These experiments should be conducted within 6 month. Long term objective: Determine the lowest dose of erythromycin that can inhibit growth of colonic neoplasia and CRC in patients expressing a truncated APC protein due to nonsense mutations. Examine the ability of a panel of additional macrolide antibiotics to induce APC nonsense mutation suppression using in-vitro methods. Investigators will focus on macrolide antibiotics that are currently in clinical use and are administrated for long terms. These objectives should take around 6 month and will be conducted in parallel.

This is a single center, non-randomized phase IIa study to determine the tolerance and safety of Abraxane (ABX) in combination with cisplatin (DDP) in patients with advanced nasopharyngeal carcinoma (NPC). Patients in whom the standard therapy had failed or had been infeasible will be eligible.The safety and efficacy will be evaluated according to NCI-CTCAE V4.0 and RECIST 1.1 respectively.

Primary: To evaluate the efficacy of capecitabine in combination with oxaliplatin (XELOX) in terms of overall response rate (based on RECIST criteria) in patients with metastatic NPC without prior chemotherapy for relapse. Secondary: To evaluate the efficacy profile of oxaliplatin (XELOX) in patients with metastatic NPC in terms of time to progression of disease, survival time, duration of response and complete response rate. To study the safety and tolerability of the regimen in patients with metastatic NPC.

Familial adenomatous polyposis (FAP) leads to adenomas and eventual adenocarcinomas in colon and less frequently, duodenum. Chemopreventive strategies have been studied in FAP patients to delay the development of adenomas and cancers. The non-steroidal anti-inflammatory drugs (NSAIDs) and selective cyclooxygenase-2 inhibitor have shown the regression of colorectal and duodenal adenomas in FAP patients. However, these drugs showed gastrointestinal damage and cardiovascular risks, and new preventive strategies are needed. Niclosamide, an anti-helminthic drug, has recently been suggested to have a suppressive effect on tumorigenesis via inhibition of Wnt pathway, and have no significant safety issues. The investigators devised a double-blind randomized controlled trial to evaluate the effect of niclosamide on polyps of colorectum and duodenum in FAP patients.

The central hypothesis is to test Low Dose Fraction Radiotherapy (LDFRT), as a potentiator of Docetaxel and Cisplatin efficacy in locally advanced nasopharyngeal cancer.

Fourty Patients will be randomly assigned in a 1:1 ratio to recieve treatment with 8 capsuls (2*4 capsuls/day) of wholistic Turmeric capsules (Pukka herbs) or placebo for six months.

Verify that 3DV+TPS is non-inferior compared to existing imported TPS and superior to existing domestic TPS.

Radiation therapy remains the principal treatment for nasopharyngeal carcinoma (NPC). The most frequently occurred radiation-related side effect is probably the radiation-induced oral mucositis (OM), which affects up to 100% of NPC patients receiving radiation therapy. When severe, oral mucositis increases the risk of infection and may compromise clinical outcomes by necessitating treatment breaks, dosage reductions, and reduced therapy compliance. In China, a quadruple mixture, composed of dexamethasone, gentamicin, vitamin B12, and procaine, is commonly prescribed when NPC patients begin to suffer from radiation-induced OM. However, the incidence of radiation-induced OM is still quite high. Oral Ulcer Gargle (FORRAD®) is a proprietary viscous liquid mucoadhesive hydrogel formulation. It creates a palliative barrier over injured mucosa, to prevent and to cure radiation-induced OM. The objective of this randomized phase II study is to assess the efficacy and safety of Oral Ulcer Gargle (FORRAD®) as an intervention for radiation-induced OM in the treatment of NPC, compared with the commonly used quadruple mixture, which is composed of dexamethasone, gentamicin, vitamin B12, and procaine.
