110 Clinical Trials for Various Conditions
ACT-MBC prospectively assesses the impact of CTCs on treatment decisions, response assessment and prognosis in MBC patients.
This study is designed to evaluate the presence and numbers of circulating tumor cells (CTCs) and cancer related gene expression levels in subjects with localized high-risk prostate cancer (HRLPC) and from subjects with non-metastatic disease experiencing biochemical recurrence and castration-resistance (BCRLPC and NMCRPC groups, respectively) who are about to undergo next generation imaging (NGI, such as Axumin® or PSMA PETCT). The investigators will also evaluate subjects with localized indolent prostate cancer who are on active surveillance (AS) as a control population. The CTC and gene expression results will be evaluated for association with disease state and progression and survival.
The purpose of this study is to collect clinical specimens from subjects with a diagnosis of colorectal cancer/advanced adenoma or undergoing a screening colonoscopy and meeting study eligibility criteria.
The purpose of this pilot study is to evaluate the addition of carvedilol with standard of care treatment to determine if it will improve progression-free survival in the front line setting in patients with glioblastoma multiforme (GBM). In addition, monitoring of circulating tumor cells (CTCs) by a real-time reverse transcriptase polymerase chain reaction (qRT-PCR) assay to correlate with the clinical findings.
Subjects will receive standard chemotherapy and Tumor Treated Fields (TTFields) and will also receive Carvedilol for 4 cycles of treatment. Carvedilol will start at 6.25 mg orally twice a day and be increased to 12.5 mg orally twice daily after 1 to 2 weeks if tolerated. Peripheral glioma circulating tumor cells (CTC) and brain MRI with and without contrast will be obtained at baseline, 2 cycles, and 4 cycles to determine the efficacy and direction of change of the CTC using a new assay tool. Preliminary assessment of the tolerability of Carvedilol with standard chemotherapy will also be evaluated.
Create a living biobank of PDOs from Stage I-III lung cancer patients.
The purpose of the study is to evaluate the impact on progression-free survival (PFS) with the combination carboplatin - pembrolizumab in patients with CTC (circulating tumor cells) positive, HER2 negative metastatic breast cancer previously treated with anthracyclines and taxanes. Previous studies have indicated that recurrent breast cancers are more resistant to chemotherapy and maybe associated with a weak immune system. This study is investigating the use of an immune therapy drug, pembrolizumab, that has the ability to restore the capacity of controlling and killing cancer cells of an important component of your immune system called T-cells. Pembrolizumab has been found effective in other types of cancer and has already been approved by FDA for those indications, but the efficacy in breast cancer is still unknown. In this study, pembrolizumab will be combined with chemotherapy to increase the cancer cell killing. There is no control or placebo treatment in this study.
The purpose of this study is to identify circulating tumor cells in patients with solid tumors. Quantify and characterize these cells, collect patient information in regards to the patient's cancer. Develop a database and a sample repository where future analysis could be done.
The purpose of this study is to look at the amount of cancer cells in the blood of participants who are being treated with denosumab. The other purpose is to look at how long it takes for cancer to get worse when participants are being treated with denosumab. Circulating tumor cells (CTCs) in the blood of patients with metastatic breast cancer (MBC) have been associated with shorter survival than when CTCs are absent, especially in patients whose cancer has spread to their bones. In this study, we want it see if denosumab (the study drug) will decrease the number of CTCs measured in patients with MBC and cancer that has spread to their bones. We also plan to get blood from participants to study other research markers of interest.
This pilot study purpose of this study is to describe peripheral circulating immune cell profiles at baseline and change on treatment with immune checkpoint inhibitors in renal cell carcinoma and urothelial carcinoma.
This study looks at the level of circulating tumor elements (cancer cells or DNA pieces floating in the blood) and how it may be related to how the tumor responds to standard treatment in patients with rectal cancer that has spread to nearby tissue or lymph nodes (locally advanced). Researchers will also compare the level and genetic characteristics of circulating tumor elements between individuals with rectal cancer and healthy individuals to understand how they may change over time. Information from this study may help researchers better understand rectal cancer.
The purpose of this study is to investigate the feasibility of using novel decellularized tissue matrices to isolate and culture circulating tumor cells (CTCs) collected from patients with metastatic solid tumor malignancies.
The purpose of this research study is: * To test blood for the presence of tumor derived circulating tumor cells (CTCs) or circulating tumor DNA (ctDNA) using an investigational medical device called the LiquidBiopsy®. Using the LiquidBiopsy® platform, recovered cells or DNA can also be investigated to obtain genetic information that may be useful to treating physicians in understanding disease. * To test blood for natural killer cells (NK cells), which are part of the body's natural immune defense against tumors. A device called the NK VueTM Kit will be used for this test. The LiquidBiopsy® is a new investigational device. An investigational device is one that is not approved by the United States Food and Drug Administration (FDA). The NK VueTM Kit is an investigational device in the United States but is approved in Canada and South Korea as a class II device. If a tumor is present, very tiny numbers of tumor cells or the contents of these tumor cells can get dislodged from the tumor and swept into the bloodstream. The LiquidBiopsy® device is able to purify the tiny numbers of tumor cells or ctDNA in the blood. Even if a tumor is too small to be found by other means such as an x-ray, it is possible that ctDNA or CTCs may be found in the blood. Genetic information can then be recovered from these cells or DNA to look for genetic changes that are related to the abnormal growth in a tumor. This will potentially allow researchers to study tumor cells or tumor DNA from a blood sample instead of a biopsy sample. This may influence cancer diagnosis, treatment and drug selection in the future. NK cells occur naturally in the body and kill tumor cells. This study will measure the activity of the NK cells in blood. A strong correlation between low NK cell activity and increased circulating tumor cells in blood has been reported.
The primary objective of this study is to establish circulating tumor cell (CTC) derived xenografts and assess the activity of novel DNA repair inhibitors as a function of DNA repair mutations detected in CTC samples (personalize DNA repair therapy).
This clinical trial is for men with advanced prostate cancer that may have spread to other parts of the body. Currently, once prostate cancer cells have spread from the prostate to other organs it is not treatable by surgery. The purpose of this study is to treat patients with an experimental antibody (i.e. that has not been FDA approved) called J591 that attaches itself to a special protein on cancer cells called PSMA to try to eliminate these cancer cells (called circulating tumor cells) from the circulation. In the initial phase of the study, 6 participants will receive the experimental J591 treatment. Routine blood tests, research blood tests, physical exam will be performed at each visit. Participants will also be asked to complete a questionnaire about how they are feeling. Participants will have a radiographic scan every 3 months to check the status of their disease. Participants who tolerate the treatment well may be re-treated at the same level every 3 months, and may continue on treatment as long as they are responding to therapy and not experiencing unacceptable side effects.
The purpose of this study is to investigate the level of Circulating Tumor Cells (CTCs) in cancer patients before and after undergoing treatment regimens where the primary treatment modality is radiation therapy (XRT). Specifically, there is interest in the change in CTCs pre- and post- XRT, both in absolute and relative terms.
The primary objective of this study is to determine whether circulating tumor cells (CTCs) can be used as a non-invasive means of confirming pathologic diagnosis in early-stage (Stage I) non-small cell lung cancer (NSCLC). Patients scheduled to undergo surgical intervention will have blood samples obtained to test for CTCs. Presence of CTCs will be compared to final pathologic diagnosis based on surgical specimens to assess the sensitivity of using CTCs alone to make a definitive diagnosis.
The purpose of this study is to isolate and measure circulating tumor cells in the blood stream to advance detection of cancer and treatment monitoring. In this study, the investigators will utilize the novel technology for circulating tumor cell detection in order to evaluate their presence in patients with lung cancer.
Purposes are to determine whether various cohorts of bladder cancer patients have detectable tCTC's, determine it tCTC levels vary with the natural history of bladder cancer and to see if tCTC's provide novel information.Study population are various cohorts of patients diangosed with urothelial carcinoma of the bladder.Procedures include a venous blood draw, up to two times, over a 6 month period for collection of tCTC's. Up to 15 mL's of blood will be collected at each blood draw.
It is hypothesized that circulating tumor cells (CTCs) from pancreatic adenocarcinoma are released into the peritoneal cavity through blood lost during the surgical resection of these tumors resulting in peritoneal recurrence despite appropriate surgical resection. Targeting the mechanisms responsible for CTC adhesion to the peritoneum may result in inhibition of implantation and growth, thus preventing this mode of pancreatic cancer recurrence postoperatively.
CTC levels collected pre-surgery will be correlated with pathological samples.
The purpose of this study is to evaluate the number of circulating tumor cells (CTC) before and after treatment using an experimental method for detecting CTC, compared to commercial CTC assay results, in patients with prostate, breast or colorectal cancers. Experiments will be done to develop a new assay technique and also test how CTC react to commonly used drugs. This information will be analyzed to determine if the experimental assays can be helpful in the future to predict how a patient's cancer may react to certain treatments. The research experiments will also attempt to grow CTC for long-term or "immortal" cell lines that can be further studied for proteins and gene mutations related to the specific tumor (not familial), and testing for sensitivity to drugs. Blood samples will be collected at specific time points during routine medical care from patients with prostate, breast, colorectal or other solid tumor cancer. Samples will also be collected from patients with no cancer for comparison purposes. Samples for the experimental tests will be identified only by codes and results will not be shared with participants. Patients with prostate, breast or colorectal cancer will also have blood samples drawn for commercial CTC assays as part of their standard care.
This pilot study will aim to determine whether circulating tumor cells (CTCs) can be captured using the novel cMET based ferrofluid. The primary objective of this pilot study will be to describe the numbers of c-MET expressing cells that can be detected by the c-MET CTC capture technique. These data will be separated by disease site. The investigator will also describe the detection rates of both the c-MET CTC capture and the EpCAM CTC capture techniques in each patient, also separated by disease site.
The primary objective of the preliminary lead-in study is to determine whether circulating tumor cells in patients with metastatic progressive castration-resistant prostate cancer or metastatic progressive breast cancer can be captured using a novel mesenchymal-marker based ferrofluid (N-cadherin or O-cadherin based). The primary objective of each comparative cohort (second stage, prostate cancer) is to compare the non-detection rate of circulating tumor cells between the standard and novel methods.
This study will evaluate a method to detect tumor cells that are circulating in the blood without getting a biopsy. The investigators already know from other studies that cancer tumors shed a small number of cells into the bloodstream every day. These are called circulating tumor cells (CTCs). Some early studies indicate the amount and type of CTCs in the blood can help determine the status of the tumor itself and the way it is responding to treatment. In this study, the investigators will compare the number of CTCs in the blood at different time frames before and after surgery to remove the prostate.
Objective: To test the sensitivity of a proprietary novel filtration device designed to capture and concentrate circulating tumor cells (CTCs).
The purpose of this study is to establish the circulating tumor cell (CTC) assay as a surrogate for tissue diagnosis of suspected primary lung cancer. This is done through evaluating clinical and molecular markers to stratify the outcome/survival in patients with thoracic malignancies treated at Yale University/Yale-New Haven Hospital, University of California San Diego/Moores Cancer Center, Billings Clinic Cancer Center.
The purpose of this research study is to determine if the EGFR mutation can be detected in CTCs. CTCs are cancer cells that are shed from solid tumors and float freely in the bloodstream. A device called the CTC-chip has been developed to find CTCs in the blood of patients with cancer. This is an experimental device. Using this device, the investigators will test participants' blood to try and find CTCs with the EGFR mutation and compare them with the results from the biopsy your doctor has recommended. The long-term goal of this research is to develop a way to test for the EGFR mutation that is less invasive than a tumor biopsy.
The purpose of the study is to determine whether the type of anesthesia during breast cancer surgery has any impact on the way a patient's immune system functions for a brief period after surgery. If the investigators find that one type of anesthesia versus the other is more beneficial to a patient's immune system, then the investigators may use this information to design a larger study to exam the effect of anesthesia better.
Utilizing CellSearch® technology, the ability to both enumerate and reliably and reproducibly characterize circulating tumor cells (CTC) for tumor markers that predict endocrine sensitivity (estrogen receptor \[ER\] and Bcl-2) and resistance (HER2 and Ki67) has been demonstrated. An algorithm for a CTC-Endocrine Therapy Index (CTC-ETI) has been constructed that can be calculated for each patient using the CTC enumeration and marker results. The primary goal of this study is to determine a CTC-ETI in ER positive, HER2 negative metastatic breast cancer patients before the initiation of a new endocrine therapy for the identification of patients that will progress rapidly.
