648 Clinical Trials for Various Conditions
The purpose of this study is to better define longitudinal genomic alterations in patients with glioblastoma (GBM), and to determine if plasma circulating tumor DNA (ctDNA) or cell free DNA (cfDNA) is associated with disease recurrence, survival, tumor characteristics, and/or peripheral immunosuppression.
This phase II trial tests whether contrast-enhanced ultrasound can predict the response of bile duct cancer to targeted radiotherapy (radioembolization treatment). Contrast-enhanced ultrasound uses gas microbubbles that may provide enhancement on ultrasound. It is also possible to pop these microbubbles using ultrasound imaging. Tumors that experience popping of these microbubbles may be easier to kill with radiotherapies. Therefore, this trial may also help doctors see if ultrasound-triggered microbubble popping can improve bile duct cancer response to radiotherapy. Another purpose of this trial is to test if the pressure inside the tumor estimated through ultrasound can be used to predict the tumor response to radiotherapy.
This study aims to assess real-world tumor response in pre/perimenopausal HR+/HER2- metastatic breast cancer (MBC) patients initiating palbociclib + aromatase inhibitor (AI) or AI alone as first-line therapy during the period on or after 01 January 2010 to on or before 30 June 2020. Data will be obtained from structured data fields within an electronic health record (EHR) database and will be supplemented by additional unstructured data collected through a targeted chart review.
Researchers are looking for a better way to treat people with solid tumors. Before a treatment can be approved for people to take, researchers do clinical trials to better understand its safety and how it works. In this trial, the researchers want to learn about regorafenib taken together with nivolumab in a small number of participants with different types of tumors. These include tumors in the head and neck, the esophagus, the pancreas, the brain, and the biliary tract. The biliary tract includes gall bladder and bile ducts. The trial will include about 200 participants who are at least 18 years old. All of the participants will take 90 mg of regorafenib as a tablet by mouth. The dose of regorafenib can be adjusted up to 120 mg or down to 60 mg by the doctor based on how well a participant tolerates treatment. All of the participants will receive 480 milligrams (mg) of nivolumab through a needle put into a vein (IV infusion). The participants will take treatments in 4-week periods called cycles. They will take regorafenib once a day for 3 weeks, then stop for 1 week. In each cycle, the participants will receive nivolumab one time. These 4-week cycles will be repeated throughout the trial. The participants can take nivolumab and regorafenib until their cancer gets worse, until they have medical problems, or until they leave the trial. The longest nivolumab can be given is up to 2 years. During the trial, the doctors will take pictures of the participants' tumors using CT or MRI and will take blood and urine samples. The doctors will also do physical examinations and check the participants' heart health using an electrocardiogram (ECG). They will ask questions about how the participants are feeling and if they have any medical problems.
This work explores the possibility of using ultrasound imaging and spectroscopy as a way of monitoring cell death, hence, tumour response to treatment. The hypothesis here is that it can be used as a way of monitoring early response to cancer treatment and predicting which patients continue on in their therapy to have a complete pathological response as a primary endpoint and tumour size decrease as a secondary endpoint. If this work is successful it could be used in the future early on in a cancer patient's treatment to predict whether or not a course of chemotherapy or radiotherapy is going to be successful. For example, in patients in which the analysis indicates a poor response the chemotherapy regimen could be changed to a more efficacious one or for those receiving radiotherapy predicted to have a poor response a radiosensitizing agent could be used to improve outcome.
This study is being conducted to determine whether the combination of imaging agents 68-Ga RM2 and 68-Ga PMSA11 is better at assessing response to high intensity focused ultrasound (HIFU) or high dose rate (HDR) local therapy than standard imaging or biopsy in patients with known prostate cancer.
This is a single institution, observational research study in which patients are observed using DWI/DCE MRI imaging before and after receiving neoadjuvant anti-HER2 therapy.
The purpose of this study is to determine the effectiveness of the combination of abemaciclib and fulvestrant in treating this type of cancer and to determine the types and severity of side effects caused by treatment with abemaciclib and fulvestrant.
The current study aims to provide validation results of RNA Disruption Assay (RDA) as a tumour response assessment tool that uses tumour core biopsies taken starting from 35 +/- 4 days after the initiation of neoadjuvant chemotherapy.
This proposal explores the novel hypothesis that the variability in outcomes within the Intermediate Risk(IR) HPV-positive Oropharynx Squamous Cell Carcinoma(OPSCC) cohort can be exploited to identify a subpopulation that exhibits outcomes similar to Low Risk (LR) HPV-positive Oropharynx Squamous Cell Carcinoma and therefore would be appropriate candidates for radiation dose de-escalation approaches. Current literature using PET, CT, and MRI as single imaging modalities have identified certain criteria within heterogenous patient populations that are associated with clinical outcomes. Here, the investigators will test the hypothesis that multiparametric analysis of simultaneously-acquired MRI and PET quantitative imaging biomarker data from the primary tumor prior to initiating therapy, after 2 weeks of chemoradiation(CRT), and 3 months following completion of chemoradiation in patients with Intermediate Risk HPV-positive Oropharynx Squamous Cell Carcinoma will generate parametric maps that are predictive of clinical outcome. Furthermore, the investigators will collect blood samples prior to, during, and after radiation therapy to evaluate whether levels of detected circulating tumor cells correlate with response to treatment.
The purpose of this study is to test the ability of a breast MRI biopsy to accurately diagnose a complete tumor response to the neoadjuvant chemotherapy (NAC) that the patient just finished. Numerous studies have shown that MRI has the highest accuracy for diagnosing a complete tumor response. The investigator wants to see if in a certain group of women who's breast cancer is no longer visible on the post-treatment MRI that the biopsy specimens from a MRI guided biopsy will accurately diagnose a complete tumor response to treatment which may in the future make breast surgery unnecessary in some women.
This research study is studying the TriNav ("TriSalus") for increasing delivery of chemotherapeutic agents delivered trans-arterially to intermediate stage Hepatocellular Carcinoma ("HCC") (Barcelona Clinic Liver Cancer (BCLC) class B; locally advanced, liver restricted disease patients. The names of the study interventions involved in this study are: -Trans-arterial chemoembolization ("TACE") with or without the utilization of Surefire
The purpose of this study is to determine if MRI imaging can detect genetic, proteomic, and metabolomic characteristics of liver tumors. The study also aims to determine if these imaging characteristics are correlated with clinical outcomes.
This early phase I trial studies how well dynamic contrast enhanced molecular resonance imaging (DCE-MRI) and technetium-Tc99m sestamibi molecular breast imaging (MBI) work in assessing tumor response to chemotherapy in patients with triple negative breast cancer (TNBC) who are undergoing chemotherapy. Investigational imaging scans such as MBI and DCE-MRI may help researchers predict which patients may respond to treatment.
Background: * There are several ways to treat prostate cancer. Researchers want to see how well a certain kind of imaging helps detect prostate cancer. They also want to see if a particular drug combination used before surgery will benefit people with prostate cancer that hasn't spread in the body (non-metastatic). The combination will be androgen deprivation therapy and enzalutamide. * The combination of androgen deprivation therapy and enzalutamide has been shown to make patients with advanced (metastatic disease) live longer. The investigators want to see if using it earlier can increase cure rate of surgery and identify genetic or molecular characteristics that are associated with better outcomes. Objectives: - To develop better ways of detecting prostate cancer before and after pre-operative treatment. Eligibility: - Men at least 18 years old with non-metastatic prostate cancer. They must be candidates for a radical prostatectomy. Design: * Participants will be screened with medical history, physical exam, and blood tests. They will have scans and X-rays. * Before starting the study drugs, participants will have: * Vital signs taken, medical history, and blood tests. * Electrocardiogram (ECG) heart test, with patches stuck on the skin. * Small piece of tumor removed (biopsy) using image guidance from magnetic resonance imaging (MRI) and ultrasound. * 3T multi-parametric magnetic resonance imaging (mpMRI). Participants will lie on a table that slides into a metal cylinder. A probe will be inserted in the rectum. They will be in the scanner for about 60 minutes, lying still. The scanner makes loud knocking sounds. Participants will get earplugs. * Participants will take the 2 study drugs for 6 months. * Enzalutamide is taken as 4 pills once a day. * Androgen deprivation therapy is given by injection 2 times over 6 months. * During these 6 months, participants will visit the clinic monthly. They will have physical exam, vital signs, and blood drawn. * After finishing the study drugs, participants will have another 3T mpMRI. Then they will have prostate removal surgery.
The purpose of this study is to determine whether an experimental alternative imaging method, Near Infrared Spectroscopy (abbreviated as NIR), can be used with a controlled respiratory system to examine the breasts for cancer. The NIR system uses light beams to produce an image or picture of the inside of the breast. The respiratory system will help researchers get more information about the breast tissue by changing the amount of oxygen the tissue receives during NIR imaging.
This study aims to develop methods for quantitative imaging of solid tumors in patients who are receiving immunotherapies that have a delayed mechanism of action. PET imaging with \[18F\] 2-deoxy-2-(18F)fluoro-D-glucose (FDG) is a potent diagnostic tool and is able to detect melanomas and other tumors, some of which are undetectable by CT. FDG PET is now used commonly in detecting melanoma in humans as melanomas quite consistently have high glucose metabolism. PET with FDG can image the response of tumors to therapy, but has not been extensively evaluated in melanoma nor in immunotherapy for melanoma. PET has been shown to be highly predictive of outcomes of patients following radioimmunotherapy of lymphoma, and has shown changes in tumor glycolysis as early as 7 days after immunotherapy initiation. In order to develop PET/CT as a tool to detect early evidence of response in patients with solid tumors receiving immune checkpoint blockade, investigators propose to perform PET/CT imaging prior to therapy, again between days 21 and 28, and finally at 4 months post-treatment initiation. Each scan will be assessed qualitatively and quantitatively. Investigators will use the PERCIST criteria to determine peak and maximum standardized uptake values corrected for lean body mass (SUL) in tumor, tumor volumes, and tumor total glycolytic volumes, and will use CT from PET/CT to measure tumor size by immune RECIST criteria. (See section on Outcome Evaluation below.) Investigators will assess whether early changes in tumor metabolism seen on FDG PET are predictive of progression free and overall survival outcomes. Through these systematic pilot studies, investigators hope to better link FDG PET measurements to individual patient responses to immune checkpoint blockade therapy and better understand and refine this emerging and often effective therapeutic approach.
Prostate cancer is one of most common cancers in America, affecting 1 in 6 men. External beam radiation therapy is one of the common methods to treat prostate cancer. Although radiotherapy is effective, side effects to the adjacent normal organs limit the therapeutic ratio. Those side effects are usually associated with the radiation damage of the normal tissue surrounding prostate, e.g. bladder, urethra and rectum etc. Both effectiveness and the side effects of radiation treatment are often accessed after whole course of radiotherapy, which makes the early intervention difficult. The current research project is a feasibility study of utilizing advanced magnetic resonance imaging (MRI) techniques to access radiotherapy treatment response of prostate cancer during and right after radiotherapy. Many advanced MRI techniques, e.g. spectroscopy (MRS), diffusion-weighted (DWI), dynamic contrast enhanced (DCE) perfusion weighted images, have been used in radiology departments for diagnostic purpose. This research project is to study the feasibility of using advanced MRI sequences to monitor tissue response during and after radiotherapy. The tissue changes revealed from MRI can provide physicians early information on possible tumor recurrence and normal tissue toxicity, therefore, the early intervention may be possible to spare normal tissue and cure the patient. The project is designed to combine several different advanced MRI imaging techniques systematically to study tissue changes during radiotherapy, which has not been seen elsewhere to date. Another important goal of this research project is to study the feasibility of associating functional MRI with radiation treatment dose distribution. Tissue response during radiation treatment depends on dose. The functional MRI can provide more information than simple anatomic information. Mapping the functional MRI spatially and associating them with 3D dose distribution in radiation treatment planning system is one important step to quantitative assess the relationship between radiation treatment and tissue changes due to the radiation.
Background: * Gastrointestinal cancers are among the most commonly diagnosed cancers in the United States. * There are currently no tests to predict how patients with gastrointestinal cancers will respond to radiation therapy or which patients may develop side effects from treatment. * Studies on tumor cells in the stool, urine, or blood from patients may provide valuable information that can be used to develop tests to determine which patients may need more or less aggressive therapy. * Studies of other substances in the stool, urine, or blood from patients may provide valuable information that can be used to develop tests to determine which patients are likely to develop side effects from radiation treatments. Objectives: * To collect blood, urine and stool specimens from patients with gastrointestinal cancers who will undergo radiation therapy. * To study hormone and protein changes in these blood, urine and stool specimens before, during and after radiation treatment in order to develop a way to predict how gastrointestinal cancers will respond to radiation therapy and if patients with these cancers will develop side effects from radiation treatment. Eligibility: -Patients 18 years of age and older with cancer of the gastrointestinal tract (esophagus, stomach, pancreas, rectum) who plan to receive radiotherapy to the site of the cancer on an National Cancer Institute (NCI) protocol Design: Participants undergo the following procedures: * Tumor biopsy: Before any treatment or at the time of surgery if it is the first treatment * Urine collection: Before, during, and after treatment and at follow-up visits. * Stool collection: Before, during, and after treatment and at follow-up visits. * Blood collection: Before, during, and after treatment and at follow-up visits. * Intestinal permeability assessment: Before any treatment, before radiation (if radiation is not the first treatment), 1 month after radiation is completed, and 3 months after radiation is completed. This test determines how the patients intestines are working to absorb sugar and may provide information about side effects from radiation treatments. Patients fast after midnight, then drink a small glass of sugars, and then do a 6-hour urine collection.
This phase II trial studies how well genetic testing works in predicting tumor response in patients with stage I-III HER2 negative invasive breast cancer. Genetic testing is a procedure that tests tumor samples to learn if certain genes are activated (turned on) in the tumor and if the activation of these genes may predict if the tumor will be sensitive or resistant to routine breast cancer treatments, such as chemotherapy or hormonal therapy.
Patients with pancreatic cancer are treated with combinations of surgery, radiation therapy and chemotherapy, depending on the location of the cancer and other individual patient health factors. The goals of therapy are to reduce or eliminate the cancer cells, but without serious damage to normal cells. Investigators at The University of Michigan are conducting a research project, to see if treatment effects on an individual patient's cancer cells can be detected early by new imaging tests in patients with resectable pancreatic cancer undergoing neoadjuvant chemoradiotherapy.
We will use magnetic resonance imaging (MRI) to investigate tumor changes in women with breast cancer who are receiving anthracycline-based systemic chemotherapy. We will also use MRI and cognitive tests to study the possible effects of chemotherapy on the brains of these women. The results will be compared to a control group of normal healthy women. We will try to determine if MRI can be used to predict tumor response and cognitive changes related to the chemotherapy.
The clinical trial is evaluating a multi-component active immunotherapy designed to stimulate an immune reaction to specific tumor associated antigens which are highly expressed on melanoma
In patients with breast cancer who undergo neoadjuvant chemotherapy or neoadjuvant hormone therapy molecular breast imaging (MBI) is an accurate test for assessing response rate to neoadjuvant therapy.
RATIONALE: Studying samples of blood in the laboratory from patients receiving pemetrexed disodium may help doctors learn more about the effects of pemetrexed disodium on cells. It may also help doctors understand how well patients respond to treatment. PURPOSE: This laboratory study is looking at blood samples from patients with stage III or stage IV non-small cell lung cancer enrolled in clinical trial MCCRC-RC0524 to determine the effect of pemetrexed disodium on cells.
RATIONALE: Collecting samples of tissue from patients with cancer to study in the laboratory may help doctors predict how well patients will respond to treatment with certain chemotherapy drugs and plan the best treatment. PURPOSE: This laboratory study is looking at tumor tissue samples to predict response to chemotherapy in patients with ovarian cancer, fallopian tube cancer, or primary peritoneal cancer.
To test the ability of new imaging techniques to monitor and predict response of pancreatic cancer to radiation and/or chemotherapy.
This exploratory clinical study is designed to obtain pre-therapeutic imaging assessments in 20 evaluable patients with metastatic renal cell cancer (RCC) and an early post therapy assessment at baseline and at various early time points (1 week in 5 patients, 2 weeks in 5 patients, 3 weeks in 5 patients and 4 weeks in 5 patients) after institution of standard approved sunitinib therapy at 37.5 mg/day. The clinical imaging biomarkers will include an assessment of tumor metabolism \[Bannasch 1986, Frauwirth 2002, Garber 2006, Kelloff 2005, Pauwels 1998, Semenza 2001, Smith 1999, Smith 2000, Sokoloff 1977, Warburg 1956, Weber 1977A, Weber 1977B\] (dynamic FDG-PET); tumor proliferation \[Rasey 2002,Shields 2001, Shields 1998, Vesselle 2002, Schwartz 2003\] (dynamic FLT-PET); tumor blood flow (H215O-PET, DCE MRI)\[Lodge 2000\], tumor perfusion (DCE-MRI)\[Tofts 1999, Tofts 1997, Parker 1999\]; and tumor blood volume (H215O-PET, DCE MRI)\[Lodge 2000, Tofts 1999, Tofts 1997\] in the same patient at baseline and then in the same patient at one of the post therapy time points (1 week, 2 weeks, 3 weeks or 4 weeks). We hypothesize that by using this set of imaging assessments it will be possible to determine an individual or more likely a set of imaging derived biomarkers that will accomplish several of the goals of the initiative which is providing funding for the study.
The study hypothesis is that the radiofrequency (RF) ablation is a safe and effective treatment for malignant lung tumors.
