About this study

Official title: A Phase II, Open-label, Multicenter Trial to Investigate the Clinical Activity and Safety of Avelumab in Patients With Advanced, Metastatic High Grade Neuroendocrine Carcinomas NEC G3 (WHO 2010) Progressive After Chemotherapy

The purpose of the AveNEC trial is to investigate the clinical activity and safety of avelumab in patients with NEC G3 (WHO 2010), including "NET G3" who are progressive after first line chemotherapy.

Read the detailed description

According to the WHO classification of 2010, Neuroendocrine neoplasms (NEN) are divided into well to moderately differentiated neuroendocrine tumors (NET), which are graded depending on their proliferation status into NET G1 (Ki67 index < 2%) and NET G2 (Ki67 2-20%), and into the poorly differentiated high grade neuroendocrine Carcinomas (NEC G3, ki67 > 20%), which - depending on their morphology - are subdivided into small cell as well as large cell NECs. The vast majority (60-90%) of patients with high grade NEC are metastasized at the time of diagnosis with distant metastases present in approximately two third of the patients.

G3 neuroendocrine neoplasia according to the WHO classification of 2010 are not a homogenous entity. Based on clinical and morphological criteria a differentiated subgroup with a Ki67 in the lower proliferative range (usually between 20-55%) which is unofficially termed "NET G3", can be subdivided from the more aggressive and undifferentiated "classical" NEC G3.

The prognosis of patients with metastatic NEC G3 is poor, and median overall survival has been reported to be 5 months with a 2-year survival rate of 11 % in the SEER data base for gastrointestinal NEC. In two large series of GEP-NEC, median survival was 12-19 months for patients with best available therapy (mainly platinum based chemotherapy) and as short as 1 month for those receiving only best supportive therapy. In contrast to the "classical" NEC G3 with a poorly differentiated morphology and a Ki 67 > 55%, NET G3 typically do not respond as well to a platinum based chemotherapy but a have a somewhat better prognosis with a 4-months longer median survival as compared to classical NEC G3. Therefore, according to current guidelines other treatment options like temozolomide based chemotherapy may be considered as a first line therapy in patients with differentiated "NET G3" .

There is a strong and unmet medical need for a novel and effective second line treatment option for these highly aggressive and rapidly progressing tumors. Considering the lack of any other established therapeutic option and the very limited efficacy of alternative second or third line chemotherapy in patients with NEC G3 (WHO 2010) who are progressive after a first-line chemotherapy, the availability of a novel therapeutic option with a significant clinical benefit (SD; PR; CR) in at least 30 % of the patients and with tolerable side effects would represent an important and clinical highly relevant break through in the treatment of these aggressive tumors.

There is a strong rationale for investigating PD-1/PD-L1 blockade in NEC G3 (WHO 2010). High grade NEC as well as LCNEC of the lung show a high mutational load, what is associated with a strong immunogenicity and a better response to an anti-PDL1/PD1 immunotherapy, and increased PDL1 expression has been demonstrated in high grade NEC. In intermediate NET the degree of T-cell tumor infiltration was associated with recurrence and survival and in a study with 80 patients with bronchopulmonary NEN including high grade NEC the expression of PD-L1 and PD-1 was associated with a worse prognosis. Evidence from phase 2 to 3 trials shows antiproliferative efficacy of an anti-PDL1/PD1 immunotherapy in high grade NECs. Furthermore, Merkel cell carcinomas, which are classified as high grade neuroendocrine tumors, are sucessfully treated with Avelumab.

Avelumab is a fully human antibody that binds PD-L1 and blocks the interaction between PD-L1 and PD-1. This removes the suppressive effect of PD-L1 on anti-tumor CD8+ T cells, resulting in restoration of cytotoxic T cell response.

Given the important role of PD-L1 in the suppression of T-cell responses, and the mode of action of avelumab which blocks the interaction between PD-L1 and its receptors, avelumab is being developed as a potential therapy for subjects with various tumors.

It is assumed that at least 20-30 % of patients with progressive disease after at least one first line chemotherapy will show a significant and clinically highly relevant benefit which is defined as an objective tumor response with complete remission (CR), partial remission (PR) or stable disease (SD) according to RECIST1.1.

    Measured: 8, 16, 24, 36, 48, 60 weeks

  4. Duration of disease control

    Duration of disease control: Duration of disease control is defined as the time from the first disease control (CR, PR, SD) to progression of disease (PD) according to RECIST1.1.

    Measured: up to 1 year

  5. Time to response (TTR)

    Time to response (TTR): TTR is the time from the first dose of trial medication to the first documentation of either complete response (CR) or partial response (PR) according to RECIST1.1.

    Measured: up to 1 year

  6. Median Progression-free survival time (PFS)

    Median Progression-free survival time (PFS). The time from first dose of trial medication to first documentation of objective tumor progression (PD) or to death due to any cause, whichever occurs first.

    Measured: up to 2 years

  7. Overall survival (OS) and survival rate after 1 and 2 years

    Overall survival (OS) and survival rate after 1 and 2 years: Overall survival is defined as the time from first dose of trial medication to date of death due to any cause. Survival rate is defined as rate of subjects surviving for at least 1 year or 2 years after first application of trial medication.

    Measured: up to 2 years

  8. Quality of life (QoL)

    Quality of life (QoL) assessed by the EORTC QLQ-C30 questionnaire on Screening/Baseline, during Treatment on every assessment, on End of Treatment and on Safety FU visit

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Avelumab in people with Cancer, run by Johannes Gutenberg University Mainz at 4 sites in Germany.

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 26 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 25 Feb 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Germany. 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 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 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?

disease control rate (DCR) after 16 weeks of avelumab treatment (time frame: 16 weeks). 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 NCT03352934, which also lists 1 linked publication.

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 25 Feb 2022.
