About this study

Official title: Randomized Open Label Study to Compare the Efficacy and Safety of Everolimus Followed by Chemotherapy With Streptozotocin- Fluorouracilo (STZ-5FU) Upon Progression or the Reverse Sequence, in Advanced Progressive Pancreatic NETs (pNETs)

The purpose of this study is to compare streptozotocin (STZ) vs everolimus as first line treatment for advanced pNET and to elucidate which sequence of STZ based chemotherapy and the mammalian Target of Rapamycin (mTOR) inhibitor, everolimus, gives better results in terms of second Progression Free Survival (PFS) in well differentiated and advanced pancreatic NETs.

Read the detailed description

STZ plus 5-Fuorouracil (5FU) is the actual standard of care for advanced pancreatic Neuroendocrine tumours (pNETS) in the European Union. Everolimus has been recently approved for its use in advanced pNETs by the Food and Drug Administration (FDA) and in Europe by the European Medical Agency (EMA).

A randomized study is needed to have a clear knowledge about the best sequence for its administration; this is, before or after palliative chemotherapy.

There may or may not be any benefits from giving first each other treatment of the study. The information obtained from this study will help the physician improve the treatment and management of patients with advanced pNET.

This study was planned to compare STZ-5FU chemotherapy followed by everolimus upon progression versus the reverse sequence. However sequential studies with pNETs are hard to be managed in terms of time and costs. Therefore the protocol was amended to have PFS1 (progression free survival after course 1) as primary endpoint and PFS2 (i.e. progression free survival after both STZ based chemotherapy and Everolimus or the reverse order) as secondary endpoint. This information will be extremely valuable for the day to day clinical practice of pNETs oncologists

What is being measured

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

  1. First Progression Free Survival (PFS1)

    Proportion of patients who are alive without progression to Course 1 from the date of randomization in STZ based CT vs Everolimus arms

    Definitions for PFS rate for course 1 at 12 months:

    • No: number (proportion) of patients who were not alive and progression free according to the respective definition (main, conservative, and optimistic);
    • Yes: number (proportion) of patients who were alive and progression free according to the respective definition (main, conservative, and optimistic).

    Measured: At 12 months

Secondary outcomes (11)
  1. Second Progression Free Survival (Second PFS)

    PFS of Course 1 (PFS1) + interval between treatments + PFS of Course 2 (PFS2), where PFS1 represents progression free survival of Course 1 and PFS2 represents progression free survival of Course 2

    Measured: Until the end of study every 12 weeks, approximately up to 5 years

  2. Progression-free Survival (PFS) to First Treatment

    Time from the date of randomization to the date of first disease progression.

    Measured: Throughout the study period every 12 weeks, approximately up to 5 years

  3. Adverse Events (AEs) Rate

    Number of patients expiriencing adverse events, treatment-related AEs and serious adverse events (SAEs)

    Measured: Throughout the study period in continous monitoring at every visit for approximately up to 5 years

  4. Frequency of Dose Modifications to First Treatment

    Percentage of patients who require a dose reduction or interruption for management of adverse events during the study period

    Measured: Throughout the study period, approximately up to 5 years

  5. Best Overall Response (BOR) to First Study Treatment

    Best response achieved with the first study treatment according to RECIST V1.0

    Measured: Throughout the study period, every 12 weeks up to approximately 5 years

  6. Objective Response Rate (ORR) to First Study Treatment

    The ORR is defined as the number of patients having as their BOR to first treatment either Complete response (CR) or Partial Response (PR) measured by RECIST criteria version 1.0.

    Measured: Throughout the study period every 12 weeks, up to approximately 5 years

  7. Frequency of Dose Modifications to Second Treatment

    Percentage of patients who require a dose reduction or interruption for management of adverse events during the study period

    Measured: Throughout the study period, approximately up to 5 years

  8. Overall Survival (OS)

    The median OS defined as the time from the date of randomization until death from any cause. This is estimated by kaplan meier method.

    Measured: Throughout the study period, up to approximately 5 years

  9. Best Overall Response (BOR) to Second Study Treatment

    Best response achieved with the second study treatment according to RECIST V1.0

    Measured: Throughout the study period, every 12 weeks up to approximately 5 years

  10. Objective Response Rate (ORR) to Second Study Treatment

    The ORR is defined as the number of patients having as their BOR to second treatment either Complete response (CR) or Partial Response (PR) measured by RECIST criteria version 1.0.

    Measured: Throughout the study period every 12 weeks, up to approximately 5 years

  11. Progression-free Survival (PFS) to Second Treatment

    Time from the date of first dose of second treatment to the date of second disease progression.

    Measured: Throughout the study period every 12 weeks, approximately up to 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Drug: Everolimus and STZ-5FU in people with Neuroendocrine Tumors, run by Grupo Espanol de Tumores Neuroendocrinos at 37 sites in 8 countries.

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 9 inclusion and 14 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 11 May 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 37 sites in Germany, France, Spain, Denmark, Netherlands and 3 more countries. 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 phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 11 May 2025). 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?

First Progression Free Survival (PFS1) (time frame: At 12 months). 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 11 May 2025.
