Renal Cell Carcinoma, Metastatic

The purpose of this observational study is to assess the role of plasma concentration monitoring of treatment drugs for patients with metastatic renal cell carcinoma (mRCC) in terms of efficacy and side effects. It furthermore holds microbiome characterization of CPI-treated patients. Furthermore, the investigators examines the role of anti-drug antibodies and receptor polymorphisms in CTLA-4 and PD-1 receptors in treatment failure among patients with mRCC treated with check point immunotherapy (CPI). Moreover, polymorphisms in the UGT1A1 gene will be correlated with the pazopanib treatment dose.

BACKGROUND: For synchronous metastatic renal cell carcinoma (RCC), surgical resection of the primary tumor in the presence of distant metastases has been the standard of therapy for select patients followed by systemic therapy. In the era of TKIs two randomized trials, CARMENA and SURTIME, have questioned the role and timing of surgery in these patients, results point towards no surgery or a deferred approach. RATIONALE: The antitumor activity of immune checkpoint blockage (ICB) is more potent than other therapy in mRCC. The deferred cytoreductive nephrectomy approach ensures systemic therapy for all patients, avoid systemic treatment delay, and spare surgery in patients with progressive tumors. Current data only point towards a survival benefit for cytoreductive nephrectomy in intermediate risk patients, but not in poor risk patients HYPOTHESIS: Deferred cytoreductive nephrectomy after initial nivolumab combined with ipilimumab or a TKI/IO-combination will improve OS in patients with synchronous metastatic RCC and ≤3 IMDC risk features This is an open, randomized, multicenter comparison trial, designed to evaluate the effect of deferred cytoreductive nephrectomy compared with no surgery following initial nivolumab combined with ipilimumab or a TKI-combination, in mRCC patients with IMDC intermediate and poor risk.

One of the most relevant targets in the field of novel targeted anticancer therapy is the family of receptors to fibroblast growth factor receptors (FGFRs). FGFR1 is the main representative of the FGFR family. The goal of this clinical trial is to learn if monoclonal anti-FGFR1 antibody (OM-RCA-01) works to treat metastatic cancers expressing FGFR1. It will also learn about the safety of drug OM-RCA-01. The main questions it aims to answer are: 1. What medical problems do participants have when receiving drug OM-RCA-01? 2. What dose of the drug should patients receive in the next studies? 3. Does tumor growth slow down in patients receiving OM-RCA-01? All patients in this study will receive the antibody treatment. The drug will be given through a vein (by IV infusion) every two weeks, for as long as the disease remains under control and the treatment is well tolerated.

This phase III randomized controlled trial evaluates the efficacy of stereotactic body radiation therapy (SBRT) in oligometastatic renal cell carcinoma. The study aims to determine if the addition of SBRT to standard systemic therapy prolong survival compared to the standard systemic therapy alone. In addition, the study will explore the impact of this combined modality therapy on patients' toxicity and quality of life. The researchers will compare SBRT plus standard systemic therapy to standard systemic therapy alone, which is targeted agents and immunotherapy in this case, to determine if SBRT could prolong survival.

Prospective, randomised, feasibility study of patients with localised or metastatic renal cell carcinoma (RCC) comparing standard palliative dose radiotherapy to a high-dose hypofractionated regime. Primary aim • To demonstrate feasibility of a randomised study comparing high-dose hypofractionated radiotherapy versus standard palliative dose radiotherapy in localised or metastatic renal cell carcinoma The aim is to recruit a minimum of 24 patients; 12 to the control arm and 12 to the high-dose regime. 2 treatment arms, no placebo: * Control arm - standard palliative-dose radiotherapy, 30Gy in 10 fractions in 3Gy per fraction over 2 weeks * High-dose arm - high-dose radiotherapy, 30Gy in 5 fractions in 6Gy per fraction on alternate days/2-3 fractions a week over 2 weeks

The aim of this study is to evaluate the effect of two decision aids for renal cell carcinoma (RCC) on the decision-making process and the quality of the decision.

This open-label Phase 1 study will evaluate the safety, tolerability, PK characteristics and preliminarily efficacy of JMKX003948 tablets in patients with renal cell carcinoma.
