About this study

Official title: Phase I/II Study of Pembrolizumab and Cabozantinib in Patients With Metastatic Renal Cell Carcinoma

This is a phase I/II open-label study designed to evaluate the combination of pembrolizumab and cabozantinib in subjects with locally advanced, recurrent, or metastatic renal cell carcinoma. Sequential dose escalation of cabozantinib with standard dose pembrolizumab will occur in the phase I dose escalation part of the study to determine the recommended phase 2 dose (RP2D). Subsequently, subjects will receive cabozantinib at the RP2D in combination with pembrolizumab in the phase II dose expansion part of the study.

Read the detailed description

Primary Objectives

  • To determine the efficacy based on objective response rate [ORR = complete response (CR) + partial response (PR)] of pembrolizumab and cabozantinib when administered in combination in subjects with locally advanced or metastatic renal cell carcinoma..

Secondary Objectives

  • To characterize dose-limiting toxicities (DLTs), maximum tolerated dose (MTD), and recommended phase 2 dose (RP2D) for the combination.
  • To assess other measures of anti-tumor activity of the combination of pembrolizumab and cabozantinib in subjects with locally advanced or metastatic renal cell carcinoma.

What is being measured

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

  1. Efficacy of Pembrolizumab and Cabozantinib Based on Objective Response Rate

    Measured through the complete response (CR) + partial response (PR)] of pembrolizumab and cabozantinib when administered in combination in subjects with locally advanced or metastatic renal cell carcinoma. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.

    Measured: Beginning of study to end of study, up to 5 years

Secondary outcomes (6)

  1. Maximally Tolerated Dose (MTD) and Recommended Phase 2 Dose (RP2D)

    • The MTD is defined as the highest dose level with no more than 1 DLT reported in 6 DLT-evaluable subjects.
    • The Recommended Phase 2 Dose (RP2D) of cabozantinib will be selected based on the clinical data and will not exceed the MTD. If < 2/6 subjects experience a DLT at 60 mg daily during dose escalation, then 60 mg daily will be considered the RP2D. If ≥ 2/6 subjects experience DLTs at 60 mg daily, and ≤ 1/6 subjects experience a DLT at 40 mg daily, then 40 mg daily will be considered the RP2D. The dose of pembrolizumab will be constant at 200 mg IV every 3 weeks.

    Measured: Throughout Cycle 1, up to 21 days

  2. Dose Limiting Toxicities

    Assessed through Common Terminology Criteria for Adverse Events (CTCAE) v 4.0. Dose Limiting Toxicity (DLT) was defined as any of the following events occurring during the DLT assessment window (21 days) and is assessed by the investigator to be likely related to study treatment (pembrolizumab and/or cabozantinib).

    • Grade ≥ 3 non-hematologic, non-hepatic adverse events
    • Grade 3 nausea, vomiting, or diarrhea lasting >72 hours despite maximal medical therapy.
    • Grade ≥ 4 neutropenia (ANC < 500 cells/μL) lasting > 7 days
    • Grade ≥ 3 febrile neutropenia
    • Grade ≥ 4 anemia
    • Grade ≥ 4 thrombocytopenia, or Grade 3 thrombocytopenia associated with clinically significant bleeding
    • Grade ≥ 3 elevation of serum hepatic transaminase (ALT or AST).
    • Grade ≥ 3 elevation of serum total bilirubin.
    • ALT or AST > 3 × upper limit of normal (ULN) AND total bilirubin >2 × ULN will require permanent treatment discontinuation.

    Measured: Throughout Cycle 1, up to 21 days

  3. Progression-Free Survival

    Measured as the time it takes for an occurrence of documented disease progression. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.

    Measured: Beginning of study to end of study, or death, whichever comes first, up to 5 years

  4. Overall Survival

    Measured as the time it takes for an occurrence of death due to any cause

    Measured: Beginning of study to end of study, or death, whichever comes first, up to 5 years

  5. Disease Control Rate (DCR), AKA Clinical Benefit Rate (CBR)

    DCR is the sum of the complete response, partial response, and stable disease rates

    Measured: Beginning of study to end of study, or death, whichever comes first, up to 5 years

  6. Duration of Response

    Duration of time that patients maintain RECIST response to treatment

    Measured: Time of first response as measured by RECIST 1.1 to time of progression or death, whichever comes first, up to 5 years

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Cabozantinib and Pembrolizumab in people with Metastatic Renal Cell Carcinoma, run by University of Colorado, Denver at 5 sites 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 16 inclusion and 41 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 13 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites 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.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 17 Oct 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Efficacy of Pembrolizumab and Cabozantinib Based on Objective Response Rate (time frame: Beginning of study to end of study, up to 5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03149822, which also lists 19 linked publications.

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 13 Mar 2025; AzTrials last refreshed its copy on 8 Nov 2026.
