Active clinical trials for "Carcinoma, Renal Cell"

Antiangiogenics are the mainstay of treatment in patients with metastatic renal cell carcinoma. Conventional clinical end-points, used to measure efficacy with chemotherapeutic agents, have not been helpful in monitoring the efficacy of antiangiogenic therapy. Increasing numbers of predictive and pharmacodynamic biomarkers are being investigated that are useful surrogates for clinical response and also to identify patients early on who will benefit from this class of agents. This is valuable in avoiding unnecessary toxicity in patients and also in reducing cost implications of this expensive group of drugs. The investigators wish to explore the variability of baseline metabolomic profile in the blood and urine of patients with mRCC and characterise the inter-subject and intra-subject variability. The study of the baseline levels has not been performed in this cohort previously. This is extremely important in interpreting the emerging data of changes in the levels of the various biomarkers from various trials. This will in turn help in the development of future targeted therapies, especially Phase I/II studies where an early demonstration of target modulation is vital. This study will also help to identify the number of patients required for appropriate statistical evaluation in pharmacodynamic studies to assess biological activity, optimisation of dosing, and investigation of potential mechanisms of resistance. Study of the urinary and blood metabolomic profile in conjunction will give us an insight into the potential use of urine as a diagnostic and prognostic tool. OBJECTIVES GOAL The main objective of the study is to determine the change from baseline in metabolomic profiling in patients with clear cell renal cell carcinoma 1 month after nephrectomy or antiangiogenic treatment during 2 months

NiSAR is a Ph.D. study and consists of three substudies. Renal cancer is one of the most deadly urologic malignancies and accounts for 900 new cases and 300 deaths per year. An increase in the use of imaging diagnostics has yielded a rise in the incidental detection of small renal masses (SRM), meaning tumors <4cm (T1a). Kidney biopsies are the gold standard for diagnosing SRM but has an inherent risk of infections, retroperitoneal bleeding and in rare cases loss of kidney function. This is problematic since up to 30% of SRM are benign. This Ph.D. consists of three studies that all aim to develop new minimally invasive modalities for diagnosing SRM. Patients eligible for these studies are diagnosed with SRM at one of the departments of Urology in the southern region of Denmark. Studies 1 and 2 aims to find circulating biomarkers, in the form of DNA and messenger ribonucleic acid (mRNA) contained in micro vesicles secreted into blood by renal cell cancers and find changes in biomarkers levels after surgery. Study 3 aim to determine the potential of multiplanar MRI (mpMRI) to discriminate between benign and malign SRM. Potentially this can lead to a fundamental change of the way urologists diagnose and monitor SRM and renal cell cancer in general. The investigators will also build a research biobank for future research.

The purpose of this project is to analyze tumour tissue from a group of subjects with renal cell carcinoma, who have been treated at the Royal Marsden Hospital.

Often kidney cancer is diagnosed when the tumour is small and hasn't spread. Rather than major surgery to remove the whole kidney, image-guided ablation involving heat (microwave or radiofrequency) or freezing (cryotherapy) is often used to destroy the tumour using minimal invasive technique with much less risk and discomfort. Limited evidence suggests that ablation also activates the immune system which may help in fighting the cancer. We will investigate the immune and other changes by analysing blood samples from patients before and after ablation. Understanding this will help in designing more effective new treatments combining ablation with biological therapies.

Generally, in the trials, an observant patient is described as correctly taking 90 to 100% of the prescribed doses. Here, the 80% compliance rate will be the cut-off between observant and non-observant patients. The evaluation methodology is based primarily on a survey of patients with metastatic or locally advanced kidney cancer who have just began an oral treatment protocol. The constitution of this cohort will be made from newly treated patients included by oncologists. The survey consists of implementing a series of questionnaires with each patient of the sample throughout the course of oral cancer care. This series of questionnaires will aim to identify: the gradient of compliance of the patient with his treatment, all the factors likely to influence positively or negatively the latter, whether medical, material or socio-economic, the evolution of patient compliance during their treatment course, a patient's quality of life index through the standardized quality of life survey form (EORTC - Quality of Life Questionnaire QLQ C30 version 3). These questionnaires will be supplemented by the medical record data (including information on tolerance and possible drug interactions). The representativeness of the patients surveyed will be established by comparing the statistical characteristics of the surveyed population with those of the aggregate anonymous global data obtained by the two Medical Department of the French Regional Health Insurance of the two regions. From the data compiled by this study, different econometric models of patient behavior will seek to establish, in particular, a relationship between the probability that a given patient will be either non or poorly observant and the various variables proved to be statistically significant.

Prospective research of Matrix Metalloproteinases (MMP) 2 and 9 as predictive biomarkers in metastatic kidney cancer patients treated with 2 anti angiogenic agents (Sunitinib or Pazopanib).

Sunitinib is an oral drug used for treatment of advanced kidney cancer. The standard dose is 50mg, but many patients require a dose decrease due to side-effects. Drug levels of sunitinib vary approximately 10-fold between patients. This study will measure blood levels of sunitinib and its metabolite, and correlate these with side-effects and the response to the treatment. The study aims to establish whether blood levels change with time, and see how useful blood levels are for monitoring patients treated with sunitinib.

The study includes the recruitment of patients with advanced renal cells carcinoma and hepatocarcinoma in treatment with sorafenib. Multicenter cohort study. It is a prospective observational study.

The hypothesis of this study are as follows: Prognostic evaluation of patients based on an integrative model provides better assessment of overall survival, and thus improves setting of care goals. In a routine care population, antitumour drugs may have a significant impact on overall survival through their targeted antitumor effect, but also through their toxicity profile and their impact on comorbidities. The optimization of patient support (supportive care, drug tolerance monitoring) can have an impact on the prognosis.

The project aims to identify Nivolumab predictive biomarkers in metastatic renal cancer patients through functional evaluation of peripheral Tregs and NKs. Moreover the efficacy of new CXCR4 antagonists (PCT/IB2011/000120/ EP2528936B1/ US2013/0079292A1) will be ex vivo evaluated in modulating Tregs and NKs function
