About this study

Official title: Avelumab, Palbociclib and Axitinib in in Treatment Naive Metastatic Clear Cell Renal Cell Carcinoma.

The aim of this study is to see whether the combination of 3 drugs (axitinib, avelumab and palbociclib) is safe and effective in slowing down the growth of advanced clear cell renal cell carcinoma (ccRCC) in patients that have not received any prior systemic treatment.

The names of the study drug involved in this study are/is:

  • Axitinib
  • Avelumab
  • Palbociclib
Read the detailed description

This is a multi-center, single-arm, phase 2 study to evaluate the efficacy of the combination of axitinib, avelumab, and palbociclib in patients with untreated, advanced clear cell renal cell carcinoma (ccRCC).

This research study involves an investigational drug combination (axitinib, avelumab and palbociclib) not approved by the FDA (USA Food and Drug Administration) for treatment of advanced clear cell renal cell carcinoma (ccRCC), though the combination of axitinib and avelumab has been approved for use in advanced clear cell renal cell carcinoma (ccRCC) treatment. Palbociclib is a CDK inhibitor, which targets growing cancer cells by blocking how a phosphate molecule is added to an important regulatory protein called retinoblastoma so preventing the formation of new cancer cells.

Study procedures include screening for eligibility, study treatment, participant evaluations and safety follow visits in addition to general health status follow-up after study treatment. Participants will receive study treatment for as long as they do not have serious side effects and their disease does not get worse, and will be followed for as long as they remain on the study.

It is expected that about 25 people will take part in this research study.

Pfizer is supporting this research study by providing the study drugs (axitinib, avelumab and palbociclib).

What is being measured

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

  1. Best Overall Response Rate (ORR)

    Objective response rate (ORR) is defined as the proportion of participants achieving complete response (CR) or partial response (PR) based on RECIST 1.1 criteria on treatment. Per RECIST 1.1 for target lesions: CR is complete disappearance of all target lesions and PR is at least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taken as reference baseline sum LD. PR or better overall response assumes at a minimum incomplete response/stable disease (SD) for the evaluation of non-target lesions and absence of new lesions.

    Measured: From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, for duration of therapy assessed up to 100 months

Secondary outcomes (2)

  1. Median Progression-free survival (PFS)

    Based on the Kaplan-Meier method, median progression-free survival (PFS) is defined as the duration of time from study entry to documented disease progression (PD) or death. Per RECIST 1.1 criteria: progressive disease (PD) is at least a 20% increase in the sum of the longest diameter (LD) of target lesions taken as reference of the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. Disease progression (PD) for the evaluation of non-target lesions is the appearance of one or more new lesions and/or unequivocal progression of non-target lesions.

    Measured: From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 100 months

  2. Median Overall Survival (OS)

    Based on the Kaplan-Meier method overall survival (OS) is defined as the time from study entry to death or censored at date last known alive.

    Measured: Participants followed for long-term for survival every 6 months from the end of treatment until death or lost to follow-up, up to 2 years after treatment discontinuation.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Axitinib, Palbociclib and Avelumab in people with Advanced Clear Cell Renal Cell Carcinoma, run by Bradley A. McGregor, MD.

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 20 inclusion and 37 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: withdrawn, as of the sponsor's last update on 7 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.

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 phase mean?

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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Best Overall Response Rate (ORR) (time frame: From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, for duration of therapy assessed up to 100 months). 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 NCT05176288.

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 7 Sep 2023.
