Active clinical trials for "Kidney Neoplasms"

This study is designed prospectively to investigate the safety and efficacy of neoadjuvant PD-1 monoclonal antibody combined with cisplatin-based chemotherapy in patients with locally advanced upper urinary tract urothelial carcinoma (UTUC). Tislelizumab, an anti-programmed death protein-1 (PD-1) monoclonal antibody, was engineered to minimize binding to FcγR on macrophages to abrogate antibody-dependent phagocytosis, a mechanism of T-cell clearance and potential resistance to anti-PD-1 therapy. The safety, tolerability, and efficacy of tislelizumab in patients with PD-L1 positive urothelial carcinoma who progressed during/following platinum-containing therapy was proved in a phase 2 trial (CTR20170071). This trial focuses on the efficacy of Tislelizumab in combination with cisplatin-based chemotherapy to induce pathological down-staging of locally advanced UTUC in neoadjuvant setting.

The aim of the study is the evaluation of the ablation efficiency of the percutaneous irreversible electroporation (IRE) as primary ablation therapy of locally confined renal cell carcinoma (≤4cm, see inclusion and exclusion criteria). The ablation success will be proofed by magnet resonance imaging (MRI) and histologically after partial kidney resection or nephrectomy 4 weeks after IRE. Hypotheses: Kidney tumors ≤4cm can be ablated completely by percutaneous IRE. Surrounded structures and renal tissue can be preserved.

Approximately 30,000 new patients are introduced into dialysis and about 20,000 of them die every year in Japan. At present, about 300,000 patients are on dialysis and more than 10,000 patients are registered with the Japan Organ Transplant Network (JOTN) with the hope for a renal transplantation. If the renal function is restored by transplantation, the quality of life (QOL) improves and more than 90% are reportedly comeback to their normal life activities and get relieved from the burden of dialysis. Furthermore, it can reduce the dialysis related medical cost by as much as 50%. However, only about 1,000 renal transplantation cases are annually carried out in Japan. Among them, 80-85% are living renal transplantations offered by family members or relatives, and the rest are from deceased donors. Due to the fact that the number of deceased donors are scarce and only living renal transplantations between the family members or relatives are currently allowed in Japan, the approximate waiting time to receive a renal transplantation is 16 years. For that reason, many patients travel abroad to receive a renal transplantation. There are reports that total nephrectomies are performed as a treatment for small size (4 cm or less) renal tumors, renal stones, ureteral tumors and ureteral strictures in many cases and that many of these nephrectomized kidneys can be successfully transplanted after surgical restoration with satisfactory results. However, due to the lack of necessary evidence it is currently not allowed in Japan. Therefore, the investigators planned the present clinical study to evaluate the curative efficacy (renal function, QOL) and safety (side effects, complications or occurrence of renal cancer) of living renal transplantations between family members and relatives with restored donor kidneys after the surgical removal or repairment of a small size (4 cm or less) renal tumor or renal stone, ureteral tumor or ureteral stricture, in order to acquire necessary clinical data for potential enrichment of the renal donor pool in Japan as well as to develop useful medical care for our patients who are on dialysis for many years due to the renal failure.

RATIONALE: Sunitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Giving sunitinib before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving it after surgery may kill any tumor cells that remain after surgery. It is not yet known whether sunitinib is more effective when given before or after surgery in treating kidney cancer. PURPOSE: This randomized phase II trial is studying the side effects of sunitinib and to compare how well it works when given before or after surgery in treating patients with metastatic kidney cancer.

RATIONALE: Treating a person's lymphocytes with interleukin-2 and monoclonal antibody may help them kill more cancer cells when they are put back in the body. PURPOSE: This phase II trial is studying how well lymphocyte therapy works in treating patients with stage III or stage IV kidney cancer.

RATIONALE: Biological therapies use different ways to stimulate the immune system to try to stop cancer cells from growing. Combining interferon alfa and interleukin-2 may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of interferon alfa and interleukin-2 in treating patients with metastatic kidney cancer.

RATIONALE: Interferon alfa may interfere with the growth of cancer cells. Thalidomide may stop the growth of cancer by stopping blood flow to the tumor. It is not yet known if interferon alfa is more effective with or without thalidomide in treating metastatic kidney cancer. PURPOSE: Randomized phase II trial to compare the effectiveness of interferon alfa with or without thalidomide in treating patients who have metastatic kidney cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Biological therapies use different ways to stimulate the immune system and stop cancer cells from growing. Combining chemotherapy with biological therapy may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of fluorouracil combined with biological therapy in treating patients who have metastatic kidney or colorectal cancer.

This is a phase Ib, open, mono-center, dose-escalation, tolerability and pharmacokinetic study evaluating the Recombinant Humanized Anti-PD-1 mAb for Injection in combination with Axitinib in patients with advanced kidney cancer and melanoma who have failed in routine systemic treatment.

Phase II clinical trial to investigate the safety, clinical activity and toxicity of combinations of D-CIK and low dose anti-PD-1 antibody in patients with metastatic renal cell carcinoma treated with axitinib.
