Active clinical trials for "Carcinoma, Squamous Cell"

Angiogenesis, the formation of new blood vessel from existing vessels, is essential for tumor growth and metastasis. Antiangiogenic therapies inhibit the growth of genetically stable endothelial cells, and most tumors should starve to death with little acquired resistance. Endostatin has been shown to block endothelial cell proliferation, survival, and migration. Antitumor activity of endostatin protein has been demonstrated in various murine and human tumors in animal model studies without any detectable toxicity. Endostatin gene therapy could directly express the highly bioactive protein in vivo by means of the mechanism of eukaryotic expression system as post-translational modification and folding, as well as overcoming the challenge of the long-term storage and the cumbersome daily administration of endostatin protein. E10A is a replication-deficient recombinant adenovirus containing a wild-type human endostatin transgene constructed from serotype 5 adenovirus (Ad5). Preclinical studies demonstrated that intratumoral injection of E10A provided significant tumor growth inhibition and sustained elevation of endostatin in blood and tumor tissue in hepatocellular carcinoma, nasopharyngeal carcinoma, and tongue cancer animal models. A Phase I clinical trial of E10A we conducted showed that repetitive intratumoral injection of E10A resulted in a small and sustained elevation of endostatin in blood and had a mild antitumor activities with very limited toxicity. The major toxicity was transient and manageable fever. A randomized Phase III trial in nonsmall-cell lung cancer showed endostatin improved response rate and time to tumor progression in combination to chemotherapy. Therefore, we designed a randomized phase II trial to explore the safety and effectiveness of E10A combined with chemotherapy in the treatment of patients with head and neck cancer.

Until today, the 5-FU/cisplatin combination is the reference regimen with 30-45% response rates, which is most commonly used to treat patients with metastatic, recurrent or locally advanced, unresectable squamous cell carcinoma of the esophagus. Because the classical dose schedule of this two-drug combination is cisplatin 100 mg/m2 day 1 and 5-FU 1000 mg/m2/day continuous infusion for 96-120 hr, prolonged administration time and mucosal toxicity are inconvenient to the patients with the aim of palliation. Capecitabine, which is oral prodrug of 5-FU and mimic continuously-infused 5-FU, is being investigated in phase I, II and III trials for the treatment of gastric, gastroesophageal, and esophageal cancers, primarily in the first-line metastatic setting. In our experience, capecitabine plus cisplatin combination (XP) as a first-line treatment for 45 patients with advanced or recurrent esophageal squamous cell carcinoma demonstrated a promising anti-tumor activity with 57% of response rate and showed tolerable toxicity with convenience. Paclitaxel has been also investigated as monotherapy and in combination with cisplatin in patients with advanced esophageal cancer. A Dutch phase II study demonstrated that paclitaxel combination with carboplatin had shown an encouraging confirmed response rate of 59% with 51 patients with resectable esophageal cancer in neoadjuvant setting. Another Dutch phase II study showed 43% of response rate including 4% of CR with 8 months of response duration when paclitaxel plus cisplatin administration was given for patients with metastatic esophageal cancer. Although recently first-line palliative chemotherapy regimen in esophageal cancer has been investigated, many trials have failed to show superiority to 5-FU/cisplatin combination. Since we considered that XP or XT is more effective and convenient chemotherapy regimen than 5-FU/cisplatin, this randomized phase II study was planned to compare XP with XT in terms of efficacy and tolerability.

It is the investigators understanding that the combination of clinical trial with laboratory cellular/molecular assay is relevant to the current promising mainstream, the translational research. The design of this trial fulfills this concept and would be a good example conducting in Mackay Memorial hospital.

The purpose of this study is to determine which regimen is better for esophageal squamous carcinoma in concurrent chemoradiation(CCRT),paclitaxel or S1 plus cisplatin.

The therapy of photofrin PDT was effective in improving life quality of patients with advanced esophageal and/or gastric cardiac cancer and the time optimizing for employing laser irradiation was of great importance.The purpose of this study is to evaluate the clinical efficacy and adverse effects of Photodynamic Therapy (PDT) on esophageal and/or gastric cardiac cancer during different time after inject photofrin.

A two-arm (two cycles' versus four cycles' capecitabine combined oxaliplatin concurrent radiotherapy) randomised Phase III clinical trial was started in Oct. 2015. Definitive chemoradiotherapy is the standard regimen in Western countries for patients with esophageal cancer who can't receive surgery or reject surgery. But in China because of its severer toxic reaction, most of patients had to discontinue treatment at the halfway way. Thus, the chemotherapy regimen of capecitabine combined oxaliplatin are widely used in clinical due to its characristic of low toxic reaction. The purpose of this study is to confirm the efficacy and safety of the different cycles(two cycles and four cycles ) of Capecitabine-oxaliplatin in Chinese esophageal squamous carcinoma radical concurrent chemoradiotherapy. A total of 60 patients will be accrued from China within 2 years. The primary endpoint is overall survival and the secondary endpoints include progression-free survival, response rate, pathologic complete response rate and adverse events.

A two-arm Phase III trial was started in Oct. 2014. Definitive chemoradiotherapy with cisplatin plus 5-fluorouracil is the standard in Western countries in esophagus cancer. But in China because of its toxic reaction, most of patients stop the halfway. The purpose of this study is to confirm the difference of 2 and 4 cycles of cisplatin plus 5-fluorouracil in the definitive chemoradiotherapy for esophagus squamous cell carcinoma. A total of 210 patients will be accrued from China within 2 years. The primary endpoint is overall survival and the secondary endpoints include progression-free survival, response rate, pathologic complete response rate and adverse events.

This clinical study is designed as a phase 3,multicenter, double-blind, randomized, controlled study,to evaluate the efficacy and safety of nimotuzumab combined with paclitaxel+cisplatin（TP) compared with TP as first-line treatment for the metastatic esophageal squamous carcinoma.

Oropharyngeal squamous cell carcinoma (OPSCC) incidence is increasing rapidly in the developed world. This has been attributed to a rise in Human Papillomavirus (HPV) infection. HPV+OPSCC is considered a distinct disease entity, affecting younger patients and has a good prognosis following treatment. Subsequently, patients can live with the considerable side effects for several decades. Radiotherapy and cetuximab (Epidermal Growth Factor Receptor-inhibitor) have demonstrated similar efficacy to 'platin' chemoradiotherapy (current standard treatment containing platinum-based compounds) in head and neck cancer, but is potentially less toxic. Results of this trial will be used to determine the optimum treatment of this debilitating cancer, with the primary aim of decreasing toxicity and improving quality of life for HPV+OPSCC patients.

The purpose of this study is to determine the efficacy of nab-paclitaxel monotherapy in previously treated advanced or metastatic squamous lung cancer.
