Sunitinib is an approved treatment for metastatic renal cell carcinoma. We performed a prospective clinical trial to evaluate the safety and clinical response to sunitinib administered before nephrectomy in patients with localized or metastatic clear cell renal cell carcinoma. MATERIALS AND
Patients with biopsy proven clear cell renal cell carcinoma were enrolled in the study and treated with 37.5 mg sunitinib malate daily for 3 months before nephrectomy. The primary end point was safety.
In an 18-month period 20 patients were enrolled. The most common toxicities were gastrointestinal symptoms and hematological effects. Grade 3 toxicity developed in 6 patients (30%). No surgical complications were attributable to sunitinib treatment. Of the 20 patients 17 (85%) experienced reduced tumor diameter (mean change -11.8%, range -27% to 11%) and cross-sectional area (mean change -27.9%, range -43% to 23%). Enhancement on contrast enhanced computerized tomography decreased in 15 patients (mean HU change -22%, range -74% to 29%). After tumor reduction 8 patients with cT1b disease underwent laparoscopic partial nephrectomy. Surgical parameters, such as blood loss, transfusion rate, operative time and complications, were similar to those in patients who underwent surgery during the study period and were not enrolled in the trial.
Preoperative treatment with sunitinib is safe. Sunitinib decreased the size of primary renal cell carcinoma in 17 of 20 patients. Future trials can be considered to evaluate neoadjuvant sunitinib to maximize nephron sparing and decrease the recurrence of high risk, localized renal cell carcinoma.

Sunitinib is a tyrosine kinase inhibitor used for the treatment of renal cell carcinoma and metastatic brain tumors. Preclinical pharmacokinetic studies have shown higher sunitinib hepatic and brain e...
To assess the efficacy and tolerability of sunitinib rechallenge in the third-line or later setting in patients with metastatic renal cell carcinoma (mRCC).
We aimed to analyse clinical and gene expression profiles to predict pathologic complete response and disease-free survival using two consecutive, prospective, preoperative chemotherapy trial cohorts.
Although a significant proportion of patients with metastatic renal cell carcinoma (mRCC) are elderly, the data on the outcomes of targeted therapies in this population are limited. The aim of the pre...
Sunitinib is a standard treatment for metastatic clear cell renal cell carcinoma (mccRCC). Data on its activity in the rare variant of metastatic chromophobe renal cell carcinoma (mchRCC), are limited...
The safety and tolerability of CVX-060 have been established in the first-in-human clinical trial, CVX-060-101. Thus, this phase Ib/II trial is to assess the safety and pharmacokinetics (...
The study compare the standard treatment with nephrectomy + sunitinib to treatment with sunitinib alone without nephrectomy. This study will be the first trial on this competitive context
While sunitinib can be very helpful to treat kidney cancer, these medications can also cause side effects, including heart damage. Studies performed in the past did not look at heart funct...
The goal of this clinical research study is to learn if Sutent® (sunitinib malate), given before surgery, can help control renal cell carcinoma. The safety of sunitinib malate will also b...
This prospective study will investigate the characteristics of mRCC patients at time of CR in comparison with mRCC patients non on CR treated with Sunitinib, in order to provide some answe...
Work consisting of a clinical trial involving one or more test treatments, at least one control treatment, specified outcome measures for evaluating the studied intervention, and a bias-free method for assigning patients to the test treatment. The treatment may be drugs, devices, or procedures studied for diagnostic, therapeutic, or prophylactic effectiveness. Control measures include placebos, active medicine, no-treatment, dosage forms and regimens, historical comparisons, etc. When randomization using mathematical techniques, such as the use of a random numbers table, is employed to assign patients to test or control treatments, the trial is characterized as a RANDOMIZED CONTROLLED TRIAL.
Providing an investigational therapy to a patient who is not eligible to receive that therapy in a clinical trial, but who has a serious or life-threatening illness for which other treatments are not available. Compassionate use trials allow patients to receive promising but not yet fully studied or approved therapies when no other treatment option exists. Also called expanded access trial.
Work that is a report of a pre-planned, usually controlled, clinical study of the safety and efficacy of diagnostic, therapeutic, or prophylactic drugs, devices, or techniques based on several hundred volunteers, including a limited number of patients, and conducted over a period of about two years in either the United States or a foreign country.
Work that is a report of a pre-planned, usually controlled, clinical study of the safety and efficacy of diagnostic, therapeutic, or prophylactic drugs, devices, or techniques after phase II trials. A large enough group of patients is studied and closely monitored by physicians for adverse response to long-term exposure, over a period of about three years in either the United States or a foreign country.
Work consisting of a clinical trial that involves at least one test treatment and one control treatment, concurrent enrollment and follow-up of the test- and control-treated groups, and in which the treatments to be administered are selected by a random process, such as the use of a random-numbers table.
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...

Renal Cell Carcinoma
Renal cell cancer (renal adenocarcinoma or hypernephroma) is the most common type of kidney cancer in adults. More than 8 in every 10 (80%) kidney cancers diagnosed in the UK are this type. In renal cell cancer the cancerous cells start in the lini...
