Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages Any age
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Study population: RCC and UC patients who were treated with ICB but developed metastatis post-treatment that was resected

Who may be able to join

  • Eligible patients will include retrospectively identified patients with RCC or UC who have received treatment with ICB and achieved clinical benefit but subsequently developed a solitary new/progressive lesion that was removed surgically. Patients with other tumor types who otherwise meet criteria may be included at a later time
  • Additionally, a group of patients with RCC who have undergone a metastasectomy but who did not receive treatment with ICB will be identified. These patients may be approached for study participation to serve as a comparator group

About this study

Official title: Defining the Genomic and Histologic Landscape of Primary and Metastatic Tumors With Divergent Kinetics in Patients With Renal Cell Carcinoma (RCC) and Urothelial Carcinoma (UC) Treated With Immune Checkpoint Blockade (ICB)

This is a comparative study using resected/ biopsied tumors samples collected from renal cell carcinoma and urothelial carcinoma patients who underwent surgical removal of lesions, followed by immune checkpoint blockade (ICB) treatment targting programmed cell death 1 (PD1) but developed new lesions later were also removed and stored in the biosample repository (BSR). The histology and genomic analysis of the pre-treatment and metastatic samples from the same patient would be used to find out the changes that may have lead to metastasis. Also, metastatic samples from ICB naive patients would be collected and compared with those from ICB treated patients to find out if the metastasis in treated patients was due to development of reistance.

Being tested
Immune checkpoint inhibitor targeting PD1

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Histopathological characterization of samples from ICB treated patients

    To characterize differences in histopathology and patterns of genomic expression between baseline tumors and metastases exhibiting divergent growth kinetics ("escape" metastases) in patients treated with immune checkpoint blockade (ICB)

    Measured: 18 months

  2. Genomic characterization of samples from ICB treated patients

    To characterize expression of different genes between baseline tumors and metastases exhibiting divergent growth kinetics ("escape" metastases) in patients treated with immune checkpoint blockade (ICB)

    Measured: 18 months

Secondary outcomes (4)
  1. Histopathological characterization of samples from patients treated with targeted or observational therapy

    To characterize differences in histopathology between baseline tumors and metastases in patients with RCC treated with observation or targeted therapy.

    Measured: 18 months

  2. Comparison of Histopathological characteristics of metastatic samples from ICB naive and treated patients

    To characterize differences in histopathology and patterns of genomic expression between "escape" metastases in patients treated with ICB from patients treated with targeted therapy or observation.

    Measured: 18 months

  3. Genomic characterization of samples from patients treated with targeted or observational therapy

    To characterize differences in patterns of genomic expression between baseline tumors and metastases in patients with RCC treated with observation or targeted therapy

    Measured: 18 months

  4. Comparison of genomic characteristics of metastatic samples from ICB naive and treated patients

    To characterize differences in patterns of genomic expression between "escape" metastases in patients treated with ICB from patients treated with targeted therapy or observation.

    Measured: 18 months

Questions about this trial

What is this clinical trial studying?

An observational study of Renal Cell Carcinoma and Urothelial Carcinoma, run by Fox Chase Cancer Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 22 May 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Histopathological characterization of samples from ICB treated patients (time frame: 18 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 May 2026.
