Active clinical trials for "Carcinoma, Squamous Cell"

It has been well established that malignant tumors tend to have low levels of oxygen and that tumors with very low levels of oxygen are more resistant to radiotherapy and other treatments, such as chemotherapy and immunotherapy. Previous attempts to improve response to therapy by increasing the oxygen level of tissues have had disappointing results and collectively have not led to changing clinical practice. Without a method to measure oxygen levels in tumors or the ability to monitor over time whether tumors are responding to methods to increase oxygen during therapy, clinician's reluctance to use oxygen therapy in usual practice is not surprising. The hypothesis underlying this research is that repeated measurements of tissue oxygen levels can be used to optimize cancer therapy, including combined therapy, and to minimize normal tissue side effects or complications. Because studies have found that tumors vary both in their initial levels of oxygen and exhibit changing patterns during growth and treatment, we propose to monitor oxygen levels in tumors and their responsiveness to hyperoxygenation procedures. Such knowledge about oxygen levels in tumor tissues and their responsiveness to hyper-oxygenation could potentially be used to select subjects for particular types of treatment, or otherwise to adjust routine care for patients known to have hypoxic but unresponsive tumors in order to improve their outcomes. The overall objectives of this study are to establish the clinical feasibility and efficacy of using in vivo electron paramagnetic resonance (EPR) oximetry-a technique related to magnetic resonance imaging (MRI)-to obtain direct and repeated measurements of clinically useful information about tumor tissue oxygenation in specific groups of subjects with the same types of tumors, and to establish the clinical feasibility and efficacy of using inhalation of enriched oxygen to gain additional clinically useful information about responsiveness of tumors to hyper-oxygenation. Two devices are used: a paramagnetic charcoal suspension (Carlo Erba India ink) and in vivo EPR oximetry to assess oxygen levels. The ink is injected and becomes permanent in the tissue at the site of injection unless removed; thereafter, the in vivo oximetry measurements are noninvasive and can be repeated indefinitely.

This is a single arm phase II study, in which 2 cycles of chemotherapy (5FU/CDDP) and immunotherapy (durvalumab and tremelimumab) are administered every 3 weeks with concurrent radiotherapy for inoperable locally advanced esophageal squamous cell carcinoma. Four weeks after completion of CCRT combined with immunotherapy, 2 cycles of durvaluma and tremelimumab will be administered every 4 weeks and thereafter durvalumab monotherapy Q4W will be maintained until unacceptable toxicity or disease progression, or for maximum 2 years after enrollment.

This is an open-label, single arm, multi-center study, assessing efficacy and safety of BI-754091 in combination with afatinib as treatment in patients with advanced or metastatic ESCC refractory to at least 1 line of systemic treatment (including chemotherapy or radiation therapy).

The incidence and mortality of esophageal cancer are at the forefront in China, among which the elderly patients account for a large proportion. Concurrent chemoradiotherapy is the standard treatment for inoperable locally advanced esophageal cancer. Most elderly patients with esophageal cancer cannot tolerate concurrent chemotherapy because of complications and other reasons. Immunotherapy has definite efficacy and low toxicity in advanced esophageal squamous cell carcinoma, and the results combined with radiotherapy have also been preliminarily reported. Therefore, it is necessary to further explore the efficacy and safety of radiotherapy combined with immunotherapy in elderly patients with esophageal cancer.

This study is being conducted to explore the efficacy of SHR-6390 and SHR-1020 in the treatment of esophageal squamous cell carcinoma after progression on PD-1 Antibody.
