Filter by:The purpose of this study is to test if an imaging agent called Zr-DFO-pertuzumab that finds HER2 proteins can be used to take pictures of HER2-positive cancer.
A Phase I of Olaparib with Radiation Therapy in Patients With Inflammatory, Loco-regionally Advanced or Metastatic TNBC (triple negative breast cancer) or Patient With Operated TNBC with Residual Disease.
To prospectively collect blood and tumor tissue from esophageal cancer patients to identify specific esophageal cancer mutations that can be measured in the blood (cell free DNA) during the course of treatment as a marker of response and recurrence.
This phase II trial studies how well cobimetinib and atezolizumab work in treating participants with rare tumors that have spread to other places in the body (advanced) or that does not respond to treatment (refractory). Cobimetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving cobimetinib and atezolizumab may work better in treating participants with advanced or refractory rare tumors.
To determine the safety and feasibility of 89Zr-Df-IAB22M2C as an immunoPET tracer; determine the best time window and protein dose for imaging; determine the pharmacokinetic (PK) and biodistribution of the probe; and to determine imaging parameters for optimal lymphoid and tumor visualization.
The radiation exposure resulting from medical imaging is a topic of some concern. Nuclear medicine provides potentially life-saving information regarding physiological processes, and is of particular value in children where the rapid and unequivocal diagnosis of pathological concerns is essential for the health of these patients. The overall objective of this investigation is to optimize pediatric patient absorbed dose by keeping it as low as possible while maintaining excellent diagnostic quality of nuclear medicine images. This is particularly important since children are at increased risk due to the enhanced radiosensitivity of their tissues and the longer time-period over which radiation effects may manifest. Current dosimetric estimations in children are based on either animal biokinetic or pharmacokinetic data from adults due to paucity of data that exists for children. This situation will be improved through the following specific aims: - Collect image-based pharmacokinetic (PK) data from patient volunteers in different age groups scheduled for routine nuclear medicine studies for F-18 fluorodeoxyglucose (FDG), a radiopharmaceutical commonly used in pediatric nuclear medicine - Pool and analyze the data for different age groups for each radiopharmaceuticals and - Generate biokinetic models to be used in subsequent dosimetric models for the optimization of pediatric nuclear medicine procedures. Since inadequate pharmacokinetic data currently exist in these patients, the investigators will use the data acquired in this study to establish PK models applicable to different age categories. Data on the pharmacokinetics of agents used in pediatric nuclear medicine are almost completely lacking. Internationally adopted dose coefficients (mSv/MBq) for pediatric nuclear medicine make age-dependent adjustments only for patient size and anatomical differences, while time-dependent kinetics from adult PK models are assumed due to the lack of kinetic data for children. The data obtained from this study will make it possible for the first time to determine how the PK in pediatric patients differs from adults. This will be done for F-18 fluorodeoxyglucose (FDG), a radiopharmaceutical commonly used for pediatric nuclear medicine imaging. The overall hope is that results will allow the molecular imaging community to implement pediatric dose-reduction approaches that substantially improve upon current guidelines pointing to future technological advances that could yield even greater dose-reduction while simultaneously improving diagnostic image quality.
As many as 70-85% subjects diagnosed with a follicular lesion on biopsy and undergoing surgery will have benign lesions verified by histopathology after surgery. Currently there is no method of pre-operatively diagnosing benign follicular lesions, as a result these subjects will have had surgery for diagnosis of a benign lesion. The aim of this study is to see whether shear-wave elastography, a new ultrasound technology can help pre-operatively diagnose benign follicular lesions. If successful, a lot of patients will not need surgery for the diagnosis of a benign lesion. The main goal of this study will be to evaluate the diagnostic accuracy of a new ultrasound technology (shear-wave elastography - SWE) for the diagnosis of malignancy in follicular lesions. Participants who have been diagnosed with a follicular lesion on thyroid biopsy and are scheduled for thyroid surgery will be eligible to participate. All participants will undergo a detailed ultrasound examination prior to their surgery. The results of the ultrasound will be compared with histopathology after surgery to test the diagnostic accuracy of SWE.
The prevalence of thyroid nodule is worldwide high. About 40% of normal population has thyroid nodules and about 5% are malignancy. It is important to differentiate malignancy from benign nodules because the management is completely different. Nowadays, the gold standard is fine needle aspiration cytology (FNAC) examination. The overall sensitivity and specificity is fair (~90%), but still has its limitation that some results are indeterminate in about 15% of the nodules. These obstacles are especially troublesome for papillary and follicular thyroid cancer that leads to delayed diagnosis, incomplete resection, and repeated operation. Preoperative evaluation of the prognosis is extraordinary important for cancer management. However, current prognostic scoring systems is only applicable after surgery. Hence, we urgently need a better risk-stratification system for individual-tailored treatment, and genetic-based computerized morphometry study seems to be the most realistic and promising one. The goal of this study is to propose a reliable method for diagnosis and prognosis of papillary thyroid cancer and follicular thyroid cancer through analyzing cellular morphologic characteristics.
The key purpose of the main part of the study is to assess efficacy and safety of anetumab ravtansine as monotherapy or combination therapy for mesothelin expressing advanced solid tumors. The main purpose of the safety lead-in (dose-finding) part of the study is to determine the safety and tolerability of anetumab ravtansine in combination with cisplatin and in combination with gemcitabine, and to determine the MTD of anetumab ravtansine in combination with cisplatin for mesothelin expressing advanced cholangiocarcinoma and in combination with gemcitabine for mesothelin expressing advanced adenocarcinoma of the pancreas. Patients will receive anetumab ravtansine every three weeks in monotherapy for most indications. In cholangiocarinoma and adenocarinoma of the pancreas, 3-weekly anetumab ravtansine is administered in combination with cisplatin or gemcitabine respectively (both administered in a 2 week on / 1 week off schedule). Treatment will continue until disease progression or until another criterion for withdrawal is met. .Efficacy will be measured by evaluating the tumor's objective response rate. Radiological tumor assessments will be performed at defined time points until the patient's disease progresses. Blood samples will be collected for safety, pharmacokinetic and biomarker analysis. Archival or fresh biopsy tissue will also be collected for mesothelin expression testing and biomarker analyses.
This dose escalation and dose expansion study is to evaluate and characterize the tolerability and safety profile of single agent KN035 in Chinese adult subjects with unresectable advanced carcinoma.
