Brief Summary

  • The standard first line treatment in SCCAC is the association of 5-FU with cisplatin reaching a percentage of survival at 5 years of about 32% (Faivre 1999); in a recent case series of patients affected by SCCAC, the combination of 5-FU and cisplatin as first line treatment produced 34.4% objective response rate (ORR) and a 5 years survival rate of 15% (Sclafani 2017);
  • No standard second line treatment exists for SCCAC;
  • Cetuximab in association with irinotecan has demonstrated promising results in pretreated patients affected by SCCAC (Lukan 2009). In addition, it was recently tested in stage I-III SCCAC in association with cisplatin plus 5-FU and radiotherapy. Despite not reaching their pre-specified endpoints both studies reported an interesting activity in local control of disease, leading to hypothesize that cetuximab warrant further investigation in new strategies (Garg 2017, Sparano 2017);
  • Anti-PD1 treatments such as nivolumab and pembrolizumab showed promising activity in metastatic refractory SCCAC in terms of response rate and disease control with acceptable toxicity profiles (Morris 2017, Ott 2017);
  • The induction of immunogenic cell death was recently shown for cetuximab-based regimens (Pozzi 2016) and PD-L1 blockade should lead to NK cells activation enhancing cetuximab ADCC (Concha-Benavente 2015, Concha-Benavente 2016). On the basis of these considerations, the investigators designed the present randomized phase II trial of avelumab alone or avelumab plus cetuximab for previously treated unresectable locally advanced or metastatic SCCAC.

Outcome Measures

Primary Outcomes (1)

  • Primary endpoint is Objective Response Rate (ORR).

    The primary endpoint is Objective Response Rate (ORR). ORR is defined as the percentage of patients, relative to the total of enrolled subjects, achieving a complete (CR) or partial (PR) response, according to Response Evaluation Criteria In Solid Tumors (RECIST) v1.1 criteria. The determination of the radiological response will be based on the investigator's reported evaluation.

    Radiological responses will be evaluated starting from cycle 1 day 1 of treatment until disease progression, withdrawal of consent or death for any reason, whichever occurs first assessed up to 12 moths.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Histologically proven diagnosis of SCCAC;
  • Progression on or after first line systemic therapy for surgically unresectable or metastatic disease. Systemic radiosensitizing chemotherapy with curative intent in limited-stage disease should be considered equal to a first line for a patient experiencing progression during or within 6 months of completion;
  • Evaluable disease lesion according to RECIST v1.1 criteria;
  • Availability of tumor sample (primary and/or metastatic sites);
  • Age ≥ 18 years;
  • Eastern Cooperative Oncology Group - Performance Status (ECOG PS) ≤ 2;
  • Life expectancy of at least 12 weeks;
  • Laboratory Requirements:
  • Neutrophils ≥ 1.5 x 109 /L; Platelets ≥ 100 x 109 /L; Hemoglobin ≥ 9 g/dL; Total bilirubin ≤ 1.5 time the upper-normal limits (UNL) of the normal values and ASAT (SGOT) and/or ALAT (SGPT) ≤ 2.5 x UNL (or \<5 x UNL in case of liver metastases); Alkaline phosphatase ≤ 2.5 x UNL (or \<5 x UNL in case of liver metastases); Creatinine clearance ≥ 30 mL/min according to the Cockcroft-Gault formula (or local institutional standard method) or serum creatinine ≤1.5 x UNL;
