Trial summary

This is a multicenter retrospective study designed to compare overall survival (OS) by PD-L1 expression status in patients with RCC who have received systemic chemotherapy for recurrent or metastatic RCC, to determine whether the prognosis is worse in PD-L1-positive than in PD-L1-negative RCC.

  • No healthy volunteers
  • Adult, Older adult

Study population: Patients with recurrent or metastatic RCC who have initiated first line treatment between 1 January 2010 and 31 December 2015, with representative FFPE of nephrectomy surgical specimen which are suitable for assessment of PD-L1 expression

Who may be able to join

Who cannot join

  • 1. Malignancies other than RCC is co-existed from the time of nephrectomy and death.
  • 2. Treatment with anti-CTLA-4 antibody, anti-PD-1/PD-L1 antibodies as first-line therapy for recurrent or metastatic RCC.

About this study

Official title: A Retrospective Multicenter Analysis of PD-L1 Expression in Japanese Renal Cell Carcinoma Patients

This is a multicenter retrospective study designed to compare overall survival (OS) by PD-L1 expression status in patients with RCC who have received systemic chemotherapy for recurrent or metastatic RCC, to determine whether the prognosis is worse in PD-L1-positive than in PD-L1-negative RCC.

Total 600 RCC surgical specimens will be collected from patients who started systemic chemotherapy for recurrent or metastatic RCC between January 1, 2010 and December 31, 2015 at about 30 participating study sites in Japan.

PD-L1 expression status (IC; immune cell) on tumor-infiltrating immune cells will be evaluated by IHC, and classified by score: IC0 (PD-L1-negative) and IC1, IC2, IC3 (PD-L1-positive). Unless otherwise specified, between-group comparisons will be performed between IC0 and IC1/2/3.

What is being measured

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

  1. Overall survival in PD-L1 negative (IC0) and positive (IC1/2/3) patients.

    Overall survival is defined as the time from the initiation date of first line treatment to death due to any cause.

    Measured: Baseline

Secondary outcomes (4)
  1. Overall survival by PD-L1 expression status (IC0, IC1, IC2, IC3)

    Overall survival is defined as the time from the initiation date of first line treatment to death due to any cause.

    Measured: Baseline

  2. Overall survival after nephrectomy (including cytoreductive nephrectomy)

    Overall survival is defined the time from nephrectomy (including cytoreductive nephrectomy) to death due to any cause.

    Measured: Baseline

  3. Time to recurrence after radical nephrectomy

    Time to recurrence after radical nephrectomy is the duration from the day of surgery to diagnosis of recurrent.

    Measured: Baseline

  4. Treatment duration (first-line and second-line therapy)

    Treatment duration is the duration from the day1 of systemic therapy for mRCC to the end of the treatment.

    Measured: Baseline

Questions about this trial

What is this clinical trial studying?

An observational study of Renal Cell Carcinoma, run by Chugai Pharmaceutical at 1 site in Japan.

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 3 inclusion and 2 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: finished, as of the sponsor's last update on 30 Aug 2021. 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 Japan. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Overall survival in PD-L1 negative (IC0) and positive (IC1/2/3) patients. (time frame: Baseline). 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 30 Aug 2021.
