Filter by:This phase I/II trial studies the side effects of durvalumab, tremelimumab and hypofractionated radiation therapy in treating patients with head and neck squamous cell carcinoma that has come back (recurrent) or that has spread to other places in the body (metastatic). Immunotherapy with monoclonal antibodies, such as durvalumab and tremelimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects. Giving durvalumab, tremelimumab, and hypofractionated radiation therapy may work better in treating patients with recurrent or metastatic head and neck squamous cell carcinoma.
The goal of this project is to develop and characterise an imaging strategy for biology-guided individualisation of the proton therapy plan to improve patient outcome and quality-of-life. Positron-emission tomography (PET) studies reflecting glucose metabolism, hypoxia and physical changes of proton-irradiated tumour tissues will be performed. Patients with head and neck cancer will be studied, as these individuals frequently experience recurrences within the radiation field, often with limited therapeutic options. Severe side-effects and functional impairment, deteriorating patients' quality-of-life, limited the use of dose-escalation in recent feasibility studies of photon therapy guided by individual PET-response. However, proton therapy, currently being introduced in the Netherlands, improves the precision of radiotherapy and thereby limits the side-effects caused by irradiation of neighbouring healthy tissues. Therefore, in proton therapy dose-escalation to improve patient outcome is less restricted by toxicity. Using PET-studies of two hallmarks of radioresistance, glucose metabolism and hypoxia, side-by-side, before and early in-treatment, the predictive ability of both PET-techniques for local recurrence-free survival will be compared. A treatment plan adapted to the individual response measured by both procedures and compute tumour-dose and toxicity, will be simulated, thereby substantiating feasibility of image-guided adaptive replanning. Simultaneously to biological responses, proton therapy-induced physical changes will be studied. These atomic changes, dependent on tissue-composition and dose-deposition, are measurable by PET. It is expected that activation-PET to measure tissue-changes during therapy, a potential new biomarker of treatment efficacy, toxicity but also accuracy of treatment plan execution. Activation-PET will be related to earlier-mentioned PET-imaging of metabolism. This clinical-technological project paves the way for an interventional trial of PET-guided treatment personalisation. Activation-PET will also serve as biomarker and quality control for proton therapy and support the current development of specialised in-beam PET-technology. These PET-techniques together will help us to individualise treatment, which is of great importance for the success and cost-effectiveness of proton therapy.
This study will evaluate the efficacy and safety of atezolizumab compared with placebo as adjuvant therapy after definitive local therapy in patients with high-risk locally advanced squamous cell carcinoma of the head and neck (SCCHN)
The purpose of this first in human and proof of concept study is to characterize the safety, tolerability and initial efficacy of CLL442 in patients with Squamous Cell Carcinoma in situ (SCCis) to enable further clinical development of CLL442.
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.
The purpose of this study is to test whether 5 fraction stereotactic ablative body radiation (SABR) is safe and improves local control for early state squamous cell carcinoma of the lung. While three fraction SABR is effective for the treatment of early stage non small cell lung carcinoma (NSCLC) of all histologies, it is not safe for many patients. While four and five fraction SABR is safe, recently published data and our institutional data suggests that local control for early stage squamous cell carcinoma of the lung using the current four or five fraction SABR is suboptimal.
In this multi-institution phase I/II trial, the investigators have chosen paclitaxel and carboplatin using a schedule and doses identical to those used in the CROSS trial. Following a run-in with nivolumab alone at 240 mg IVPB every 2 weeks for 2 doses, nivolumab at 240 mg every 2 weeks will be added to paclitaxel and carboplatin, which will be dosed according to the standard of care established by the CROSS trial: paclitaxel 50 mg/m2 weekly for 6 weeks and carboplatin AUC 2 weekly for 6 weeks. Concurrent radiation will be administered with chemotherapy at 1.8 Gy/fraction × 28 fractions to a total dose of 50.4 Gy, the standard radiation dose administered in the United States for trimodality therapy that includes concurrent therapy with carboplatin and paclitaxel. A decrease in dose to 41.4 Gy per the protocol established by van Hagen, et al. will be permitted before discontinuing therapy due to unacceptable toxicity. While the CROSS study administered only 5 weekly doses of chemotherapy during the 5 weeks of radiation, the higher dose of 50.4 Gy (1.8 Gy/fraction ×28 fractions over 5½ weeks) utilized in this study permits for a sixth dose during the additional week of radiation.
This is a multicenter minimal risk or burden prospective 3-cohort follow-up and monitoring study that aims to collect clinical, socio-psychological, medico-economics data and biospecimens for patients with oral potentially malignant lesions (OPML) or resectable head and neck squamous cell carcinoma (HNSCC) : - Cohort A: OPML patients. - Cohort B (specific design): smokers (adults who have smoked at least 100 cigarettes in their lifetime) motivated to quit - either current smokers (who currently smokes cigarettes every day (daily) or some days (nondaily)) or former smokers (adults who have smoked at least 100 cigarettes in their lifetime, but say they currently do not smoke) who stops smoking within 3 months prior to the diagnosis - with a resectable HNSCC requiring postoperative radiotherapy or chemoradiation. - Cohort C: Patients with resectable HNSCC non-eligible to cohort B. The primary objective of this study is the identification of biomarkers (predictive of malignant transformation or second primary tumor) and new strategies for prevention and therapy, mainly through extensive genomic, epigenomic and immune characterization of OPML and HNSCC.
This is a study to determine the clinical benefit (how well the drug works), safety and tolerability of combining CDX-3379 and cetuximab. The study will enroll patients with advanced head and neck squamous cell carcinoma who have previously received cetuximab and progressed.
Esophageal cancer is a common malignant disease worldwide especially in china. Though esophagectomy and definitive chemoradiotherapy are standard treatments, disease relapses in many patients and the prognosis of metastatic ESCC is still poor. For patients with unresectable or metastatic ESCC, chemotherapy is an important treatment alone or with radiotherapy. Taxane, platinum, and fluoropyrimidine have been reported effective in ESCC and is used as first-line treatment of ESCC. As for 2nd-line treatment, both irinotecan and taxane had been recommended based on data from clinical trials which were most enrolled esophageal or esophageal-gastric junction adenocarcinoma and with only small sample size. Therefore, it is still urgently needed to explore effective 2nd-line treatment for ESCC. Apatinib, also known as YN968D1, is an orally antiangiogenic agents. Preclinical and clinical data had shown that it is effective in the treatment of a variety of solid tumors including esophageal cancer. It had been approved as a 3rd-line treatment for patients with advanced gastric cancer by state FDA of China in 2014. And the safety data showed that hemorrhage is rare and non-fetal which is different from bevacizumab. Therefore, the investigators initialize this phase II study to explore the efficacy and safety of irinotecan and apatinib combination treatment in unresectable or metastatic ESCC patients who failed in 1st-line chemotherapy or chemoradiotherapy.
