Filter by:Patients with head and neck cancer and are schedule to receive standard radiation therapy known as IMRT to treat cancer
RATIONALE: Radiation therapy uses high energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as cisplatin and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving radiation therapy together with cisplatin and fluorouracil may kill more tumor cells. It is not yet known whether radiation therapy and cisplatin are more effective with or without fluorouracil in treating patients with head and neck cancer. PURPOSE: This randomized phase III trial is studying radiation therapy and cisplatin to compare how well they work with or without fluorouracil in treating patients with stage III or stage IV head and neck cancer.
[F-18]HX4 is being developed as a diagnostic radiopharmaceutical for PET imaging. This trial is looking at the safety of [F-18]HX4. The Sponsor is seeking to determine if [F-18]HX4 may serve as a clinically useful hypoxia marker in diagnostic imaging, allowing the rational application of hypoxia related therapies to those patients most likely to benefit from them. Tumor hypoxia, a situation where tumor cells have been deprived of oxygen, caused cancer cells to become more resistant to the effects of radiotherapy and chemotherapy. A non-invasive study characterizing tumor hypoxia would facilitate the development of targeted therapies. The population to be studied consists of a total of ten (10) adult subjects, including, four normal volunteers and six cancer subjects, the latter with a confirmed diagnosis of head and neck cancer, as defined by the protocol eligibility criteria. The objectives of this exploratory study are to: - Gain information on bio-distribution of [F-18]HX4, and to evaluate the PET images of [F-18]HX4 for resolution, signal to background ratio for both intermediate levels of oxygenation, and at extreme levels hypoxia - Use this eIND in order to obtain the necessary information to file an IND application with the FDA. The information collected under this exploratory study will not be used for diagnostic purposes, to assess the subject's response to therapy, or for clinical management of the subject. - Begin collection of baseline imaging data - Collect [F-18]HX4 metabolism data - Gain information to improve study design and the conduct of future trials This investigation will be conducted as an exploratory, open-label, non-randomized, uncontrolled, single center, safety study. The trial is expected to begin subject enrollment in early January 2008 and end subject participation in June 2008. The duration of an individual subject's participation includes a screening visit, followed by participation in the actual study starting with the day of dosing with imaging sessions lasting several hours, concluding with a next day safety follow-up visit. Individual doses of [F-18]HX4 shall not exceed 20 mCi. The IP will be administered through a previously placed suitably sized angiocatheter or a butterfly needle. Prior to injection, qualified site personnel will assay the dose. After IP administration several PET imaging series will be acquired. Also, in order to assess major organ function and electrolyte levels, a metabolites analysis will be performed for this study from predose to 90 minutes postdose. In order to determine the quantity of [F-18]HX4 and labeled metabolites excreted by the kidney,urine will be collected and pooled at the designated intervals after administration of the investigational product. This excretion data will provide supportive information for calculating human dosimetry estimates from PET imaging biodistribution data collected in human subjects. For cancer subjects, a tissue biopsy will have been taken or be scheduled to be performed. The biopsy sample will be examined for hypoxic biomarker(s) using immunohistochemistry methods.
The main purpose of this study is to evaluate low oxygen areas called hypoxia within tumors. These low oxygen areas are thought to be the reason why tumors are more resistant to chemotherapy and radiation treatment. An imaging technique using a hypoxia tracer called fluoromisonidazole (FMISO) can detect low oxygen areas within a tumor. This imaging technique, called a PET scan, uses positively charged particles to detect slight changes in the body's biochemistry and metabolism. FMISO PET scans have been performed in patients with head and neck cancer and have shown the ability to detect low oxygen areas within tumors.
See where the dye-like material (FACBC) goes in your body and how long it stays in your body. See how much of the dye-like material is picked up by your tumor Compare the FACBC pictures with other pictures (such as FDG PET scan) that were obtained as part of your standard imaging evaluation.
chemotherapy- and radiotherapy-induced oral mucositis represents a therapeutic challenge frequently encountered in cancer patients.This side effect causes significant morbidity and may delay or interrupt the treatment plan, as well reduce therapeutic index. cyclo-oxygenase 2 (COX-2) is an inducible enzyme primarily expressed in inflamed tissues and tumor. COX-2 inhibitors have shown promise as radio- and chemosensitizer and reduce radio-induced toxicities. we have conducted a phase III, randomized double blind clinical trial to evaluate the toxicity and efficacy of celecoxib, a selective COX-2 inhibitor, administered concurrently with chemotherapy, and radiation for locally advanced head and neck cancer.
RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment with erlotinib. PURPOSE: This clinical trial is studying how well erlotinib works when given before surgery in treating patients with head and neck cancer that can be removed by surgery.
A study of Oxaliplatin and Docetaxel followed by Cetuximab for head and neck cancer patients to determine their effect on the control and reduction of tumor size
The purpose of this study is to determine if the combination of 2 chemotherapy drugs called pemetrexed and gemcitabine might be effective treatment for head and neck squamous cell cancer. The researchers want to find out what effects, good and/or bad, that this treatment has on head and neck cancer.
RATIONALE: Vaccines made from a gene-modified virus and a person's dendritic cells may help the body build an effective immune response to kill tumor cells. Celecoxib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving vaccine therapy together with celecoxib may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving vaccine therapy together with celecoxib works in treating patients with metastatic nasopharyngeal cancer.
