Filter by:In this study, Liposome Entrapped Paclitaxel Easy to Use (LEP-ETU) is being compared to Taxol® to examine whether the paclitaxel in these 2 formulations undergoes similar processing by the body. Safety and tolerability of LEP-ETU and Taxol will also be assessed. In this study, each patient will receive one intravenous infusion of LEP-ETU or Taxol, followed 3 weeks later by an infusion of the other drug, at the same dose and infusion duration. Multiple blood samples will be taken for analysis before, during, and after both drug infusions. Upon completing these 2 Cycles of treatment, eligible patients may enroll in an extension study (LEP-ETU-102B) to continue treatment with LEP-ETU. LEP-ETU is a liposomal formulation of paclitaxel, a widely used anti-cancer drug. This LEP-ETU formulation of paclitaxel is being developed to potentially reduce toxicities associated with Taxol, by eliminating the drug formulation component polyoxyethylated castor oil (Cremophor® EL). In LEP-ETU, paclitaxel is associated with liposomes, which are microscopic membrane-like structures created from lipids (fats). Thus, the LEP-ETU formulation could potentially have reduced toxicity, while maintaining or enhancing efficacy.
This is a phase II, multicenter, open-label study of cetuximab in patients with epidermal growth factor receptor (EGFR) negative, metastatic colorectal carcinoma who have progressed after receiving at least one standard chemotherapeutic regimen that included a fluoropyrimidine. Target enrollment is 80 evaluable patients. Patients with EGFR-negative metastatic colorectal carcinoma who have progressed after receiving at least one standard chemotherapeutic regimen that included a fluoropyrimidine, will receive an initial dose of cetuximab, 400 mg/m2 , intravenously (i.v.) over 120 minutes, followed by weekly treatment with cetuximab, 250 mg/m2 i.v. over 60 minutes. Patients who experience unacceptable toxicity or who have progressive disease (PD) will not receive further cetuximab therapy. Patients will be evaluated for a tumor response at a minimum of every 6 weeks while on cetuximab therapy. Patients with stable disease (SD), partial response (PR), or a complete response (CR) may continue to receive weekly cetuximab therapy, unless they are dose-delayed or discontinued because of toxicity. Patients who have a PR or CR must have a confirmatory tumor assessment no less than 4 weeks after the initial evaluation demonstrating a response. To evaluate the objective response rate, a single-stage design will be used in this study.
The purpose of this study is to determine the highest dose of Liposome Entrapped Paclitaxel Easy to Use formulation (LEP-ETU) that can be safely administered by an intravenous infusion to patients with advanced cancer.
The purpose of this study is to evaluate the safety and efficacy of Karenitecin (BNP1350) as a treatment for Malignant Melanoma.
A program for patients with non small cell lung cancer who may benefit from Iressa, but cannot enter another clinical trial due to them not being eligible, or for whom no trials are available.
This study will investigate the most effective approach for managing pain and providing palliative care (lessening of pain or symptoms). Patients with advanced cancer who are enrolled in a National Cancer Institute (NCI) protocol and will undergo major surgery as part of their treatment may be eligible for this study. Participants will be randomly assigned to pain management provided by either 1) their attending physician or 2) the Clinical Center's Pain and Palliative Care Service. Patients in the first group may be reassigned to the Pain and Palliative Care Service at any time during the study. Participants will be interviewed every 3 months for as long as 1 year about their pain, its effect on several areas of their lives, changes in their needs, and how well they think their pain is being managed.. As the patients progress through the NCI study, they will meet regularly and as often as needed with either their attending physician or the Pain and Palliative Care team. Each interview will last about 20 to 30 minutes. With the patient's permission, the interviews will be tape recorded.
The utility of PEREGRINE Monte Carlo calculations for radiation treatment planning in a clinical setting will be assessed by comparing results with other fully three-dimensional programs. ROB will investigate PEREGRINE for clinical use at NCI in collaboration with Lawrence Livermore National Laboratory (LLNL).
Patients undergoing immunotherapy for advanced cancer under IRB-approved protocols, who are to receive immune cells in adoptive transfer, will have less than or equal to 50% of those cells labeled with In-111-oxine and administered along with the remainder of their unlabeled cells. They will then undergo gamma-camera imaging over the next 0-7 days and blood samples and tumor sites which are accessible with minimal surgery (low-risk biopsy) may be sampled in some patients for enumeration of radiolabeled cells. End-points will be tumor and normal organ imaging and the amount of In-111 per gram of tissue in biopsies or per ml. of blood.
We propose to determine the response of a newly developed laser heated, vycor glass fiberoptic radiation dosimetry system to ionizing radiation in a clinical radiotherapy environment. Present systems measure only total dose or have limitations, such as instability, non-linearity, excessive size or a decoupled measurement system, making them unsuitable in a variety of clinical applications. This fiberoptic coupled dosimetry system is a new and innovative technology application which allows on-line measurement of instantaneous dose rate and total dose never before achievable. It offers a clear advantage in patient treatment delivery, allowing on-line corrections essential to a new generation of radiotherapy treatment machines with development of beam intensity modulation as an adjunct to 3D conformal therapy. It also has the advantage of submillimeter size and is minimally invasive, making it ideal for brachytherapy. This system has the potential for stable, accurate, reproducible, clinically feasible measurements of total dose and dose rate. The output of this system will be measured under various clinical conditions encountered in a clinical setting and compared against existing thermolumeniscent and diode dosimetry standards. Initial measurements will use a tissue equivalent phantom for depth dose and accuracy measurements. Additional studies will include dosimetric measurements of routine clinical treatment setups on patients receiving therapeutic irradiation.
Most bone marrow transplantations for malignant and non-malignant disease include whole body irradiation. Techniques for administering that treatment, including patient positioning, lung and soft tissue compensation, dose rate, total dose and fractionation differ between institutions. These differences are optimized at each institution to limit toxicity and maximize therapeutic outcome. Technically complex procedures such as total body radiation are subject to equipment failures. Such failures mid-treatment could be catastrophic to the patient, since therapy must be timely and compatible therapy may not be available elsewhere in the community. The purpose of this protocol is to provide backup between George Washington University Medical Center and the Radiation Oncology Branch of the NCI to allow for orderly, safe, and compatible therapies in the event of equipment failure; or replacement of a linear accelerator or any other malfunctioning equipment necessary to deliver TBI; or any emergent situation.
