Filter by:This proof-of-concept study is designed to assess the ability of [18F]AH-111585 PET imaging to detect tumors and angiogenesis. Up to 30 evaluable subjects are planned to be included at up to 2 study centers in the US. Subjects are considered evaluable if they undergo administration of AH-111585 (18F) Injection, dynamic and static PET imaging, and tumor tissue acquisition. The targeted population is adult subjects at initial diagnosis or recurrence with tumors ≥2.5 cm in diameter who are scheduled to undergo resection or biopsy of the tumor as a result of routine clinical treatment. The tumors must belong to one of the following 5 types: - High-grade glioma, including glioblastoma multiforme, anaplastic astrocytoma, and anaplastic oligodendroglioma - Lung cancer, including small cell lung cancer and non-small cell lung cancer - Head and neck (H&N) tumors, including laryngeal squamous cell carcinoma, well-differentiated thyroid and oral cavity carcinoma - Sarcoma - Melanoma Safety will be assessed from the rates of adverse events, changes in vital signs, changes in electrocardiogram (ECG) parameters, changes in physical examination findings, and changes in clinical laboratory findings. Efficacy will be assessed as the correlations between parameters derived from the PET images and the reference standards. The reference standards will be immunohistology for αvβ3 integrins and other biomarkers specific for oncology and angiogenesis and from the standard of care imaging. Measures obtained from optional DCE-CT imaging may also be used to compare the uptake and retention of [18F]AH-111585 in tumors obtained from the dynamic PET to assess functional status of the vascular system of the tumor.
Determination of efficiency of nimotuzumab in children with high grade glioma.
The purpose of this study is to determine the safety and efficacy of the combination of Gliadel wafers plus surgery and limited field radiation therapy with concomitant temozolomide followed by temozolomide given at an extended dose schedule (metronomic schedule) in patients undergoing initial surgery for newly-diagnosed high grade glioma.
A Pilot Study Evaluating Minimized Time to Beam Hypofractionated IMRT with PET Assisted Target Definition in Patients with High Grade Gliomas The aim of this pilot project is to explore the feasibility of combining a simple conformal plan (Phase I) with an IMRT treatment approach (Phase II) for high grade glioma patients with the aim of starting the RT as soon as possible following the patient's first outpatient visit (thus, minimized 'time to beam'). It is hoped that the rapid treatment start with the initial 3D CRT plan will lessen clinical deterioration due to the growth of these aggressive tumours. The use of Linac-based IMRT in Phase II of the patient's treatment plan will maintain the benefit of the sophistication of IMRT. Using novel PET imaging we also hope to better characterize regions of glioma cells thus producing more optimized planning target volumes (PTVs) for each patient and decreasing the volume of normal brain irradiated with the aim of minimizing radiation toxicities. Hopefully this planning and treatment approach will provide an improvement in the quality of life and outcome for high grade glioma patients.
RATIONALE: Current therapies for children with recurrent/progressive high grade gliomas provide very limited benefit to the patient. The anti-cancer properties of Antineoplaston therapy suggest that it may prove beneficial in the treatment of children with recurrent/progressive high grade gliomas. PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on children (> 6 months of age) with recurrent/progressive high grade gliomas.
