NCT06432036

Brief Summary

This phase I/II trial tests the safety, side effects and effectiveness of radioembolization with yttrium-90 (Y-90) in patients with early stage renal cell carcinoma. Y-90 is a radioactive chemical that is incorporated into millions of very tiny glass spheres. These spheres are injected into the artery that feeds the cancer. This process is called radioembolization. Y-90 radioembolization may be a safe and effective treatment for patients with early stage renal cell carcinoma.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Participants must be aged ≥ 18 years at the time of screening
  • Written informed consent and any locally required authorization (e.g., Health Insurance Portability and accountability Act) obtained from the patient/legal representative prior to performing any protocol-related procedures, including screening evaluations
  • Life expectancy ≥ 12 months
  • RCC, diagnosed by radiographic imaging and histology
  • Clinical stage of RCC: T1 or T2a, Cancer stage (N0M0)
  • solid (\> 80% solid) target lesions
  • Patient not an ideal candidate for partial nephrectomy or thermal ablation at the time of study entry, based on the decision of the institution's multidisciplinary tumor board. Contraindications for partial nephrectomy include inability to potentially partially resect the kidney, high risk of adverse events due to medical comorbidities, or potential high risk of adverse events due to general anesthesia. Contraindications to thermal ablation include potential inability to technically place ablation probes into the tumor, central tumors which risk thermal injury to the renal collecting system
  • Patient not considered a candidate for long-term active surveillance due to oncologic risk due to tumor growth and/or tumor size
  • Patient not considered ideal candidates for radical nephrectomy due to surgical comorbidity and/or development of adverse health outcomes
  • Measurable tumor by RECIST 1.1 criteria
  • Absence of bilateral renal tumors
  • Negative serum pregnancy test in females of child-bearing potential; patients who are breast-feeding cannot participate in this trial
  • Hemoglobin ≥ 9.0 g/dL
  • Absolute neutrophil count ≥ 1.5 x 10\^9/L
  • Absolute lymphocyte count ≥ 1.0 x 10\^9/L
  • +4 more criteria

You may not qualify if:

  • Any contraindication to angiography or selective renal artery catheterization
  • Screening angiography with cone beam CT (CBCT) shows any arterial flow to the gastrointestinal tract uncorrectable by angiographic techniques
  • Screening angiography with CBCT shows poor tumor targeting that would lead to a dose that does not meet the renal dosing criteria. This typically occurs when a feeding artery to the tumor cannot be identified
  • Screening angiography demonstrates excessive non-tumoral renal parenchyma will be in the treatment field, that the new baseline glomerular filtration rate will be \< 45 mL/min/1.73 m\^2
  • Screening angiography demonstrates renal venous shunting of iodinated contrast that is immediately visible upon arterial injection
  • Extra-renal metastases, including patients with abdominal lymph nodes \>1.5 cm in shorter axis, or with lung nodules (single lesion, \>1 cm, or multiple smaller lesions with a total diameter \>2 cm)
  • Brain metastases, leptomeningeal carcinomatosis or spinal cord compression. Patients with suspected brain metastases at screening should have an MRI (preferred) or CT each preferably with IV contrast of the brain prior to study entry
  • Evidence of any tumor invasion into the renal vein, renal artery, or renal collecting system
  • Any prior radiation therapy to the abdomen, including localized radiation therapy to the index tumor
  • Concurrent treatment for RCC or treatment in the last 6 months in another clinical study, unless it is an observational study (non-interventional) or during a non-interventional follow-up stage of an interventional study, or prior randomization to this study
  • History of active primary/acquired immunodeficiency
  • Presence of renal ureteral stent in the treatment kidney at any time
  • History of malignancy, other than RCC, within three years, with the exception of adequately treatment carcinoma in situ of the cervix, early squamous cell carcinoma or basal cell carcinoma of the skin, localized prostate cancer, ductal carcinoma in situ, or low-grade endometrial carcinoma with no myometrial invasion (negligible risk of metastases or death 5-year overall survival \[OS\] rate \> 90%)
  • Major surgical procedure (as defined by the Investigator) within 28 days prior to enrollment
  • A history of severe allergy or intolerance to contrast agents, narcotics, sedatives or atropine that cannot be managed medically
  • +6 more criteria
