Filter by:Carbonic anhydrase IX (CA IX) has been implicated in the progression of most solid tumours and expression has been demonstrated in clinical samples from a variety of solid cancers. High expression is often associated with high grade or metastatic disease and poor prognosis. CA IX is not expressed in normal tissue, potentially providing a cancer-associated target that would not likely result in significant interruption of normal biologic function in organs not affected by cancer. A humanized monoclonal antibody CA9hu-1 has shown robust activity in a variety of tumour models including models of ovarian, prostate, breast, pancreatic, colon and lung where tumour growth and metastasis are inhibited when CA9hu-1 is used as a monotherapy. Enhancement of chemotherapy has also been demonstrated in several models in combination with CA9hu-1. CA IX is also expressed by tumour-associated cells (angiogenic endothelium, tumour-associated macrophages), which also drive cancer progression. Thus, targeting CA IX with CA9hu-1 in cancer patients is expected to affect multiple pathways and multiple tumour compartments that are important to tumour progression. Taken together, there is strong rationale for developing hu-CA91 for the treatment of advanced cancer. The present study was designed to establish safety and toxicity profile and maximum tolerated dose of CA9hu-1, evaluate pharmacokinetics, investigate the presence of anti-drug antibody, to document anti-tumour activity at a clinically relevant dose, and to document the use of [18F]FLT-PET as a biomarker for detection of early tumour response at a clinically relevant dose.
This study will obtain tumor samples from patients with head and neck cancers and aims to develop personalized TCR-T therapy for head and neck cancer by determining the reactive TCR clone sequences in head and neck cancer.
The objective of this Study is to collect, process, and transfer biologic samples such as blood and/or tissue biopsies to determine the concordance of detected alterations obtained through liquid biopsy analyses compared to next generation sequencing of time-matched or archival tissue specimens from individuals with advanced solid tumors. Examples of locally advanced and metastatic tumors include stage III and IV cancers (ex. lung, breast, all gastrointestinal malignancies, all gynecologic malignancies, prostate cancer, head and neck tumors, soft tissue cancers, and melanoma). These specimens will be analyzed for diagnostic purposes and research (either by Labcorp/OmniSeq or to a third-party recipient designated by Labcorp/OmniSeq). Labcorp/OmniSeq may transfer the specimens and data to its clients, including commercial, academic or non-profit research institutions; or alternatively, may retain the specimens in its repository for future research use at the sole discretion of Labcorp/OmniSeq and or assignees. Labcorp/OmniSeq will maintain all detailed clinical information including demographic data (de-identified), ethnicity, disease state, stage (radiological, pathological and clinical-whichever is relevant).
The high-flow oxygen therapy system, also called the THRIVE (Transnasal Humidified Rapid-Insufflation Ventilatory Exchange) system, appears to provide better patient safety than conventional techniques. Panendoscopy is a very common diagnostic procedure in ENT surgery. The general anesthesia during the diagnostic panendoscopy is a good representation of the induction stage. Indeed, the procedure of preoxygenation preceding anesthetic induction and direct laryngoscopy corresponds to the airway management that is an integral part of each general anesthesia. This is why researchers are studying it in particular to improve patient safety during difficult intubations. The paradox is that there is no consensus on the anesthetic strategy for this procedure that counts four main methods for the airway management of patients requiring an ENT panendoscopy. In our center, the investigators use, in most situations, a variant of spontaneous ventilation described by Y. Jacquet et al., with the difference that the investigators use a transglottic oxygenation probe during the procedure. During laryngoscopy, the operator positions a naso-tracheal tube after local anesthesia of the vocal cords. The oxygen flow is reduced to 3 L/min before the exploration procedure. The arrival in operating theaters of the Optiflow™ system, developed by the New Zealand Company Fisher & Paykel Healthcare, has led to a rethinking of the way oxygen is delivered. This device allows the administration of a flow rate of up to 70 L/min while delivering heated gases.
NRF2 activation, observed in up to 40% of head and neck squamous cell carcinoma (HNSCC) tumors, plays a critical role in tumor progression, metastasis, and radiation therapy resistance. The investigators have recently discovered that pyrimethamine (PYR) and its analogs have an inhibitory effect on NRF2 activity in vitro and in mouse models via inhibition of dihydrofolate reductase (DHFR). Pyrimethamine is an established drug that has been used for decades for treatment of protozoan infections and malaria. A growing body of research shows that it has potential antitumor activity, however its activity on growing human tumors has not been previously studied. The primary efficacy goal of this study is to evaluate the activity of pyrimethamine on human tumors as demonstrated by inhibition of DHFR and downregulation of NRF2 pathway activity. On-target inhibition of DHFR by pyrimethamine results in the stabilization and increased protein expression of human DHFR. The primary efficacy hypothesis of this study is that treatment with pyrimethamine will result in a 50% increase in DHFR protein within the tumor cells as measured by quantitative western blot analysis. Secondarily, among those tumors classified as NRF2-active on pre-treatment biopsy, the investigators hypothesize there will be a 50% reduction in NRF2 activity as measured by SureQuant targeted proteomic analysis.
This trial evaluates how well a new therapeutic device works in managing trismus in patients who received radiation treatment for head and neck cancer. Radiation therapy is a common form of treatment in patients with head and neck cancers. However, changes to surrounding tissue following radiation therapy may lead to trismus, an inability to open the mouth fully. This can create significant functional impairment leading to malnutrition due to impaired chewing, risk of dental infections due to impaired oral hygiene, difficulty with speech, and decreased health-related quality of life. Exercise therapy is the mainstay of treatment for post-radiation trismus to help improve mobility and flexibility and increase range of mouth opening. This new device is non-invasive and is similar to other jaw stretching devices where a mouthpiece is placed between the teeth and a hand-lever is used to spread open the upper and lower jaw. However, it will also have additional sensors to measure pressure exerted by the hands and jaw as well as the distance to open the mouth which could help guide therapy. This study may help doctors customize a device to patient-specific needs, provide real-time feedback, and encourage compliance for trismus exercise therapy.
This is a feasibility study investigating the use of a high-performance HyperSight cone beam CT (CBCT) and adaptive planning software for both online and offline radiotherapy treatment planning for head and neck cancer.
The goal of this trial is to determine whether it is possible to minimize radiation dose to parts of the brain that are important for thinking and learning in children who require radiation to treat their tumor, and if this will help reduce neurocognitive (thinking and learning) impairments in these patients. Patients with newly diagnosed brain or head and neck tumors who are having radiation therapy will have neurocognitive testing and MRI imaging (both research and for regular care) done as part of their participation in the study. Survivors of childhood brain tumors who completed radiation therapy at least two years before joining the study, and have not had a recurrence, will have neurocognitive testing and research MRIs completed. Healthy children will also be enrolled and have research MRIs done. The researchers will use the radiation plan to determine how much radiation was delivered to different parts of the brain. The investigators will use the MRIs to determine how the normal brain is changing after treatment; and how this compares to patients who had standard radiation treatment or who never had a brain tumor. The neurocognitive testing will be compared among different groups to see how different treatment plans affect performance on neurocognitive tests.
Since the introduction of immune checkpoint ihibitors (ICIs) in cancer treatment, numerous studies have investigated different patient profiles to identify those who benefit from this class of drugs. Currently, hundreds of studies are being conducted with the aim of increasing the benefit of these therapies by combining ICIs with other treatments: immunomodulators, cytotoxics, targeted therapies, including cancer vaccines, which are peptides or RNA injected to trigger or increase a specific immune response against the tumor. Other approaches exist, such as oncology-specific "basket" studies, to focus on a genetic mutation independently of tumor location and determine whether a drug could treat the same genetic mutation found in several different locations. To date, ICIs are part of standard management in the US for patients with several diseases: advanced melanoma, NSCLC, Merkel cell carcinoma, head and neck squamous cell carcinoma, urothelial and renal cell carcinoma, cancers characterized by microsatellite instability, refractory Hodgkin's lymphoma, hepatocellular carcinoma, gastric cancer. In addition, trials are underway to investigate the benefit of ICIs in other locations. Thus, taking into account the growing importance of ICIs in the oncological therapeutic strategy and the large number of patients treated, a better understanding of the vascular impact of these drugs is necessary.
Recently published data suggest that stimulation of the infrahyoid strap muscles increases pharyngeal patency in patients with obstructive sleep apnea, but the innervation of these muscles by the ansa cervicalis is variable. The investigators propose a study examining the anatomic variation of the ansa cervicalis and the effect of neurostimulation on muscle recruitment.
