PURPOSE: This phase I/II trial is studying the side effects of tinzaparin and to see how well it works in treating patients with metastatic kidney cancer that cannot be removed by surgery.
- Determine the effect of tinzaparin sodium on fibrin formation (prothrombin fragment F1.2), thrombin generation (thrombin-antithrombin complexes), and fibrinolysis (D-Dimer) from baseline to 2 weeks and at nadir or disease progression in patients with unresectable metastatic renal cell carcinoma (RCC).
- Determine the effect of tinzaparin sodium treatment on circulating angiogenesis markers, including vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF).
- Determine the proportion of patients developing venous thromboembolism and hemorrhage.
- Determine the tolerability of tinzaparin sodium treatment for up to 6 months in these patients.
- Establish the feasibility of undertaking a multicenter renal cell carcinoma trial with specialized coagulation test collection, shipping, and processing.
- Obtain more accurate and specific mean, median, and variability in biomarker data in advanced RCC patients treated with tinzaparin sodium for purposes of planning larger future trials.
- Estimate the progression-free survival at 4 months in patients treated with tinzaparin sodium.
- Correlate progression-free survival with changes in markers of coagulation activation or angiogenesis.
- Correlate the anticoagulant activity of tinzaparin sodium (anti-Xa activity) with change in coagulation markers, angiogenesis markers, and progression-free survival.
OUTLINE: This is an open-label, pilot, multicenter study.
Patients receive a treatment dose of tinzaparin sodium subcutaneously (SC) once daily for 14 days followed by a prophylactic dose of tinzaparin sodium SC once daily for up to 6 months in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed periodically.
PROJECTED ACCRUAL: A total of 35 patients will be accrued for this study.

In this study the investigators will determine the safety and effectiveness of Tinzaparin in preventing blood clots for up to 12 months of treatment.
This study evaluates the pharmacokinetics of tinzaparin during renal replacement therapy. 60 patients with clinical indication for pharmacological thromboprophylaxis and slow low efficien...
Blood clots in the leg veins, known as deep vein thrombosis, are important because they may travel to the lung (known as pulmonary embolism) and cause death. Blood clots are treated with ...
The purpose of this study is to assess if accumulation of anti-Xa activity occurs after repeated daily administration of prophylactic doses of tinzaparin in patients with severe chronic ki...
The blood thinner "tinzaparin" might increase survival in patients with colon cancer undergoing surgical resection. The investigators want to assess if a trial allocating patients to prolo...
The prevalence of chronic kidney disease (CKD) is increasing worldwide in part due to population ageing. Identifying risk factors for age-related kidney function decline could help in understanding me...
The discovery of sodium storage without concurrent water retention suggests the presence of an additional compartment for sodium distribution in the body. The osmoregulatory role of this compartment u...
The safety and efficacy of low-molecular-weight heparin in the prevention of extracorporeal dialysis circuit clotting among in-center extended duration nocturnal hemodialysis (INHD) patients are unkno...
Acute kidney injury with metabolic acidosis is common in critically ill patients. This study assessed the associations between the use of IV sodium bicarbonate and mortality of patients with acute kid...
Sodium-glucose cotransporter 2 (SGLT2) inhibition has been shown to reduce cardiovascular mortality and preserve kidney function in patients with type 2 diabetes. Kidney transplant recipients with dia...
A sodium-hydrogen antiporter expressed primarily by EPITHELIAL CELLS in the kidneys, it localizes to the apical membrane of the PROXIMAL KIDNEY TUBULE, where it functions in sodium and water reabsorption and possibly calcium homeostasis. It also is expressed in heart, brain, and lung tissues and is resistant to AMILORIDE inhibition.
A sodium-glucose transporter that is expressed in the luminal membrane of the PROXIMAL KIDNEY TUBULES.
Agents that inhibit SODIUM-POTASSIUM-CHLORIDE SYMPORTERS which are concentrated in the thick ascending limb at the junction of the LOOP OF HENLE and KIDNEY TUBULES, DISTAL. They act as DIURETICS. Excess use is associated with HYPOKALEMIA and HYPERGLYCEMIA.
A complication of kidney diseases characterized by cell death involving KIDNEY PAPILLA in the KIDNEY MEDULLA. Damages to this area may hinder the kidney to concentrate urine resulting in POLYURIA. Sloughed off necrotic tissue may block KIDNEY PELVIS or URETER. Necrosis of multiple renal papillae can lead to KIDNEY FAILURE.
Sodium or sodium compounds used in foods or as a food. The most frequently used compounds are sodium chloride or sodium glutamate.
Nephrology - kidney function
Nephrology is a specialty of medicine and pediatrics that concerns itself with the study of normal kidney function, kidney problems, the treatment of kidney problems and renal replacement therapy (dialysis and kidney transplantation). Systemic conditions...
Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
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...
