Brief Summary:
Within the proposed single arm multicenter phase-II trial it is intended to investigate the feasi-bility of adding Avelumab to FOLFIRI plus Cetuximab after 4 cycles (2 months) of treatment with FOLFIRI plus Cetuximab. After 4 more cycles of FOLFIRI plus Cetuximab plus Avelumab the treatment will be de-escalated to Avelumab as a maintenance concept until progression of the disease according to RECIST 1.1 has occurred.

Condition or disease Intervention/treatment Phase
Treatment Related Cancer Drug: 5-FU Drug: Folinic Acid Drug: Irinotecan Drug: Cetuximab Drug: Avelumab Phase 2

Detailed Description:

After 4-6 months of doublet chemotherapy a de-escalation to a less toxic regimen is needed for most of the patient with mCRC. The addition of Avelumab to a cytotoxic chemotherapy regimen with FOLFIRI plus cetuximab followed by Avelumab maintenance has not been in-vestigated so far. It is known that FOLFIRI plus cetuximab leads to necrosis and therefore tumor antigens that usually are not presented to the host immune system become recogniza-ble. This effect of a triggered immune system after induction treatment with chemotherapy is currently investigated in other trials. The ongoing IMPALA trial is testing the toll-like receptor (TLR)-9 agonist MGN1703 as maintenance treatment in patients that have responded to an induction doublet chemothera-py. This effect may be enhanced by the fact that Cetuximab in Combination with 5-FU and Irinotecan triggers immunogenic cell death.

The lately published data from the interim analysis of the PACIFIC trial using the anti-PD L1 antibody durvalumab after chemoradiation in stage II non-small cell lung cancer (NSCLC) proofed the concept of an anti-PD L1 antibody as a maintenance treatment after chemoradi-ation. Durvalumab prolonged PFS significantly (HR 0.52, p<0.001).

The study is not limited to MSI-h and should be able to demonstrate Avelumab efficacy in MSS tumors. The lately presented data on the use of atezolizumab plus cobimetinib (NCT01988896) in in heavily pretreated MSS mCRC patients showed a 12-month OS rate of 43% which was higher than the 24% seen for Regorafenib in the pivotal CORECT trial. Therefore it is worthwhile to test this concept in MSS mCRC.

Furthermore part of the cetuximab effect can be attributed to ADCC (antibody derived cellu-lar cyctotoxicity) with again leads to necrosis of tumor cells and the release of antigens. Both effects together may be able to present enough tumor-neo-antigens. To boost the effect, Avelumab is able to inhibit the PD-1 derived inhibition of cytolysis and other tumor cells within the body may be attacked by the immune system which leads to an anti-tumor effect repre-sented by a prolonged PFS and finally OS of the patients.

Primary Outcome Measures :
  1. Progression free survival (PFS) [ Time Frame: up to 8 months ]
    The primary clinical objective is to determine the efficacy of a standard 1st-line regimen (FOLFIRI plus cetuximab) in patients with RAS wild-type mCRC with Avelumab mainte-nance in terms of progression free survival rate after 8 months (according to RECIST 1.1).

Secondary Outcome Measures :
  1. Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability] [ Time Frame: up to 36 months ]
    Determine safety and tolerability, according to NCI CTC AE v4.03 and to the obtained data on vital signs, clinical parameters (oxygen saturation) and feasibility of the regimen.

  2. Efficacy of experimental Regimen according to response rate [ Time Frame: up to 36 months ]
    Determine the efficacy of the experimental regimen in terms of objective response rate (acc. to RECIST v1.1 and irRE-CIST)

  3. Efficacy of experimental Regimen according to Overall survial [ Time Frame: up to 36 months ]
    Determine the efficacy of the experimental regimen in terms of overall survival.
