Main objective of the trial

The primary objective of the study is to evaluate the efficacy of CetuGEX™ for the treatment of patients with stage III/IV recurrent and/or metastatic SCCHN as compared to cetuximab (both in combination with platinum-based chemotherapy) in terms of PFS.

E.2.2

Secondary objectives of the trial

Secondary objectives are as follows:
1. To evaluate further efficacy criteria, safety and QoL of patients with stage III/IV recurrent and/or metastatic SCCHN treated with CetuGEX™ as compared to cetuximab (both in combination with platinum-based chemotherapy).
2. To assess PK parameters and profiles of CetuGEX™.
3. To assess efficacy and safety based on genetic markers for immune response (FcγR allotypes) and biomarkers.

18. Patients institutionalized by official means or court order.
19. Receipt of any other investigational medicinal product within the last 30 days before randomization or any previous CetuGEX™ administration.
20. Prior allergic reaction to a monoclonal antibody, grade 3 IRR or any grade 4 reaction to a monoclonal antibody.
21. Known sensitivity to any component of the investigational medicinal product (IMP) and medication used in this study.

E.5 End points

E.5.1

Primary end point(s)

progression-free survival

E.5.1.1

Timepoint(s) of evaluation of this end point

Screening, every 6 weeks after day of randomization until Week 18 and every 8 weeks thereafter

E.5.2

Secondary end point(s)

Secondary efficacy endpoints include:
 PFS as assessed by independent centralized reading according to modified irRC.
 Objective response rate (ORR, i.e., CR + PR) according to modified irRC at the end of combination treatment.
 Best overall response rates (CR, PR, SD) according to modified irRC including maintenance therapy treatment.
 Clinical benefit rate (CBR, i.e., CR + PR + SD) according to modified irRC.
 Overall survival (OS) defined as time from randomization until death of any cause.
 Time to treatment failure (TTF), as defined in Section 10.3.1.2.
 QoL scores assessed using EORTC-QLQ-C30 and EORTC-QLQ-H&N35H.
In addition, PFS and all secondary efficacy endpoints listed above will be analyzed by FcγRIIIa-allotype subgroups (i.e., FF, FV and VV), p16 status, and other potential parameters.
