About this study

Official title: Phase III Study of Adjuvant Pembrolizumab vs Active Surveillance After Nephrectomy in Patients With Non-Clear Cell Renal-Cell Carcinoma

This phase III trial compares the effect of pembrolizumab to active surveillance after a surgical procedure to completely or partially remove a kidney (nephrectomy) in improving time without disease in patients with non-clear cell renal cell cancer. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving pembrolizumab after nephrectomy may be more effective than the usual active surveillance approach for improving time without disease in patients with non-clear cell renal cell cancer.

Read the detailed description

PRIMARY OBJECTIVE:

  1. To evaluate whether adjuvant treatment of pembrolizumab will lead to better disease-free survival (DFS) compared to patients receiving no adjuvant treatment in the active surveillance arm.

SECONDARY OBJECTIVES:

  1. To compare overall survival (OS) between patients receiving pembrolizumab versus (vs.) active surveillance II. To assess the safety and tolerability in each arm. III. To compare DFS between patients randomized to the pembrolizumab arm vs. the active surveillance arm in patients that are circulating tumor deoxyribonucleic acid (ctDNA) positive at baseline.

IV. To compare OS between patients randomized to the pembrolizumab arm vs. the active surveillance arm in patients that are ctDNA positive at baseline.

  1. To compare the percentage of baseline ctDNA positive patients that achieve ctDNA clearance at week 12 between the pembrolizumab arm and active surveillance arm at.

VI. To compare DFS with KIM-1 status (high and low) by treatment arms. VII. To assess whether a decrease in KIM-1 after one cycle of adjuvant therapy is associated with improved DFS among patients receiving pembrolizumab.

VIII. To evaluate whether an increase in KIM 1 at predefined landmark timepoints is associated with an increased risk of subsequent DFS events.

IX. To evaluate whether persistently elevated C-reactive protein (CRP) is associated with recurrence.

EXPLORATORY OBJECTIVE:

  1. To assess DFS and OS in each histology subgroups (papillary, chromophobe, unclassified, other).

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM A: Patients undergo active surveillance, including computed tomography (CT) or magnetic resonance imaging (MRI), every 3 months for 1 year. Patients also undergo collection of blood samples on study and CT or MRI during follow up. Patients may undergo echocardiography (ECHO) and/or bone scan and/or positron emission tomography (PET)/CT if clinically indicated.

ARM B: Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1 of each cycle. Cycles repeat every 6 weeks for up to 9 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo CT or MRI throughout the trial and collection of blood samples on study. Patients may undergo ECHO and/or bone scan and/or PET/CT if clinically indicated.

After completion of study treatment, patients are followed up every 3 months up to year 2, every 6 months in years 2-5, and every 12 months in years 5-10.

What is being measured

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

  1. Disease-free survival (DFS)

    A superiority test of DFS for pembrolizumab arm versus (vs.) active surveillance arm will be performed at one-sided 0.025 significance level, using a stratified log-rank test assuming exponential failure.

    Measured: From randomization to first documented local recurrence, distant metastasis, secondary systemic malignancy, or death due to any cause, whichever occurs first, assessed up to 10 years

Secondary outcomes (9)

  1. Overall survival (OS)

    OS will be assessed among all randomized patients. Kaplan-Meier estimate will characterize OS and OS comparison will be made for pembrolizumab vs. active surveillance arm using stratified log-rank test and assuming exponential failure.

    Measured: From randomization to death from any cause, assessed up to 10 years

  2. Incidence of adverse events

    Adverse events will be described separately for patients treated on each arm to evaluate safety and tolerability. Toxicity will be defined using the Common Terminology Criteria for Adverse Events. All patients who receive treatment, regardless of eligibility, will be evaluated for toxicity. The 90% confidence interval for the true probability of observing a toxicity of Grade 4 or higher on a given arm will be no wider than 12.1% for each arm. The probability of observing one or more toxicities on a given arm with a true rate of 1% is 86.6% for each arm.

    Measured: Up to 1 year

  3. DFS among those that are circulating tumor deoxyribonucleic acid (ctDNA) positive

    The first ctDNA analysis objective is to compare DFS between patients randomized to pembrolizumab arm vs. active surveillance arm among patients that are ctDNA positive at baseline. Among patients that are ctDNA positive at baseline, DFS will be compared between patients randomized to pembrolizumab arm vs. surveillance arm using a stratified log-rank test at 0.05 two-sided alpha level assuming exponential failure. Hazard ratios (HRs) for recurrence or death will be reported using a univariable cox proportional hazards model.

    Measured: Up to 10 years

  4. OS among those that are ctDNA positive

    The second ctDNA analysis objective is to compare OS between patients randomized to pembrolizumab arm vs. active surveillance arm among patients that are ctDNA positive at baseline. Among 72 patients that are predicted to be ctDNA positive at baseline, OS will be compared between patients randomized to Pembrolizumab arm vs. surveillance arm using a stratified log-rank test at 0.05 two-sided alpha level assuming exponential failure. HRs for recurrence or death will be reported using a univariable cox proportional hazards model.

    Measured: Up to 10 years

  5. ctDNA clearance rate prediction

    Will compare ctDNA clearance rate at week 12 between pembrolizumab arm and active surveillance arm. Among the 72 patients that are predicted to have ctDNA positivity at baseline, comparison of ctDNA clearance between arms will be assessed using Fisher's exact test at 0.05 two-sided alpha level.

    Measured: At week 12

  6. DFS by KIM-1 status

    Will to compare DFS between the two arms among high baseline KIM-1 levels (> 86 pg/mL) and low baseline KIM-1 levels separately. Among patients that consent to biomarker study (n=360), DFS will be compared between pembrolizumab arm patients and active surveillance arm patients in each high KIM-1 level and low KIM-1 level subgroups separately, using a stratified log-rank test assuming exponential failure, at 0.05 two-sided alpha level. HRs will be reported using a univariable cox proportional hazards model.

    Measured: Up to 10 years

  7. DFS by KIM-1 in pembrolizumab arm

    Will assess whether a decrease in KIM-1 after one cycle of adjuvant therapy identifies patients who derive benefit from treatment. Among patients that consent to biomarker study and get randomized to pembrolizumab arm (n=180), DFS will be compared between pembrolizumab arm patients with a clinically meaningful drop in KIM-1 level after cycle 1 vs. no clinically meaningful drop in KIM-1 level using log-rank test at 0.05 two-sided alpha level. HRs will be reported using a univariable cox proportional hazards model.

    Measured: Post-cycle 1 (cycle length = 6 weeks)

  8. DFS in patients with any KIM-1 increase and not

    Will evaluate whether an increase in KIM-1 at any timepoint is associated with better DFS. Among patients that consent to biomarker study (n=360), DFS will be compared between patients with a clinically meaningful increase in KIM-1 level at any timepoint vs. no clinically meaningful increase in KIM-1 level using log-rank test at 0.05 two-sided alpha level. Hazard ratios will be reported using a univariable cox proportional hazards model.

    Measured: Up to 10 years

  9. Recurrence rate in C-reactive protein (CRP) groups

    Will evaluate whether persistently elevated CRP is associated with recurrence. Among the patients that consent to biomarker study (n=360), comparison between those with persistently elevated CRP vs. don't will be compared in recurrence rate, using Fisher's exact test at 0.05 two-sided alpha level. Odds ratio will be reported to summarize the strength of association between elevation of CRP (yes vs. no) and development of recurrence disease (yes vs. no).

    Measured: Up to 10 years
