|Condition or disease||Intervention/treatment||Phase|
|Metastatic Colorectal Cancer RAS Wild Type||Drug: Avelumab Drug: Cetuximab||Phase 2|
The primary objective of the study is to evaluate the efficacy (OS) of avelumab and cetuximab combined in pre-treated RAS wild type metastatic colorectal cancer patients. Tumor measurements by computed tomography (CT) scan or magnetic resonance imaging (MRI) will be performed every 8 weeks from the beginning of treatment to determine response to treatment. Response will be evaluated using the Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1).
Treatment will continue until disease progression, significant clinical deterioration, unacceptable toxicity, any criterion for withdrawal from the trial or trial drug is fulfilled. Treatment may continue past the initial determination of disease progression per RECIST 1.1 if the subject's performance status has remained stable, and if in the opinion of the Investigator, the subject will benefit from continued treatment and if other criteria are fulfilled as outlined in the protocol.

- Male or female subjects aged ≥ 18 years 3.Histologically proven diagnosis of colorectal adenocarcinoma.
4. Diagnosis of metastatic disease 5. RAS (NRAS and KRAS exon 2,3 and 4) wild-type in tissue at initial diagnosis. 6. Efficacy of a first line therapy containing an anti-EGFR agent (panitumumab or cetuximab) with a major response achieved (complete or partial response).
7. A second line therapy. 8. More than 4 months from last dose of anti-EGFR agent administered in first line treatment before randomization. 9.Measurable disease according to RECIST criteria v1.1 10 ECOG PS of 0 to 1 at trial entry 11. Estimated life expectancy of more than 12 weeks 12. Adequate hematological function defined by white blood cell (WBC) count ≥ 2.5 × 109/L with absolute neutrophil count (ANC) ≥ 1.5 × 109/L, lymphocyte count ≥ 0.5 × 109/L, platelet count ≥ 100 × 109/L, and hemoglobin ≥ 9 g/dL (may have been transfused) 13. Adequate hepatic function defined by a total bilirubin level
≤ 1.5 × the upper limit of normal (ULN) range and AST and alanine aminotransferase (ALT) levels ≤ 2.5 × ULN for all subjects or AST and ALT levels ≤ 5 x ULN (for subjects with documented metastatic disease to the liver).
14. Adequate renal function defined by an estimated creatinine clearance > 30 mL/min according to the Cockcroft-Gault formula (or local institutional standard method) 15. Effective contraception for both male and female subjects if the risk of conception exists (Note: The effects of the trial drug on the developing human fetus are unknown; thus, women of childbearing potential and men must agree to use effective contraception, defined as 2 barrier methods, or 1 barrier method with a spermicide, an intrauterine device, or use of oral female contraceptive. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this trial, the treating physician should be informed immediately.) Highly effective contraception for both male and female subjects throughout the study and for at least 30 days after last avelumab treatment administration if the risk of conception exists.
16. No prior immunotherapy
Subjects are not eligible for this trial if they fulfill any of the following exclusion criteria:
- Any contraindication to cetuximab and/or avelumab.
- Past or current history of malignancies other than colorectal carcinoma, except for curatively treated basal and squamous cell carcinoma of the skin or in situ carcinoma of the cervix.
- Pregnancy 4.Breastfeeding
5. Participation in a clinical study or experimental drug treatment within 30 days.
6. Subjects receiving immunosuppressive agents (such as steroids) for any reason should be tapered off these drugs before initiation of the trial treatment, with the exception of:
subjects with adrenal insufficiency, who may continue corticosteroids at physiologic replacement dose, equivalent to
≤ 10 mg prednisone daily
- intranasal, inhaled, topical steroids,
- local steroid injection (e.g., intra-articular injection)
- Systemic corticosteroids at physiologic doses ≤ 10 mg/day of prednisone or equivalent
- Steroids as premedication for hypersensitivity reactions (e.g., CT scan premedication) 7. All subjects with brain metastases, except those meeting the following criteria:
- Brain metastases have been treated locally, and
- No ongoing neurological symptoms that are related to the brain localization of the disease (sequelae that are a consequence of the treatment of the brain metastases are acceptable) 8. Prior organ transplantation, including allogeneic stem-cell transplantation 9. Significant acute or chronic infections including, among others:
- Known history of testing positive test for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome
- Hepatitis B virus (HBV) or hepatitis C virus (HCV) infection at screening (positive HBV surface antigen or HCV RNA if anti-HCV antibody screening test positive) 10. Active autoimmune disease that might deteriorate when receiving an immunostimulatory agent:
- Subjects with diabetes type I, vitiligo, psoriasis, hypo- or hyperthyroid disease not requiring immunosuppressive treatment are eligible
- Subjects requiring hormone replacement with corticosteroids are eligible if the steroids are administered only for the purpose of hormonal replacement and at doses ≤ 10 mg or equivalent prednisone per day.

Other severe acute or chronic medical conditions including immune colitis, inflammatory bowel disease, immune pneumonitis, pulmonary fibrosis or psychiatric conditions including recent (within the past year) or active suicidal ideation or behavior; or laboratory abnormalities that may increase the risk associated with study participation or study treatment administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the patient inappropriate for entry into this study.
