Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).


    The EU Clinical Trials Register currently displays   44343   clinical trials with a EudraCT protocol, of which   7372   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).

    General information about the trial
    Main objective of the trial
    To evaluate efficacy in terms of objective response rate (ORR) after 3 months of combination therapy of avelumab and cetuximab according to Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1)
    Protection of trial subjects
    The treatment should be conducted as described in the protocol. Any protocol deviations were reported. The recommendations of Good Clinical Practice (see ICH-GCP: International Conference on Harmonisation - Good Clinical Practice), valid since 17.1.1997, were met. Throughout the study, participating patients were under close observation.
    Background therapy
    Any medications (other than those excluded by the clinical trial protocol) that were considered necessary for the patients’ welfare and did not interfere with the trial drug could be given at the investigator’s discretion. At least 1 hour prior to the first infusion of cetuximab, patients had to be pretreated with an antihistamine and a corticosteroid. This premedication was also recommended prior to all subsequent infusions. Palliative bone-directed radiotherapy could be administered during the trial. Short-term administration of systemic steroid (that is, for allergic reactions or the management of irAEs) was allowed. Erythropoietin and darbepoietin alpha could be prescribed at the Investigator’s discretion. Bisphosphonate treatment was permitted if it had been started more than 14 days before the first administration of the study drug.
    Evidence for comparator
    As this was a single arm trial, no comparator was used.

    Recruitment
    Recruitment details
    After obtaining signed informed consent, screening evaluations were performed to confirm eligibiliy. Between 03-Jun-2019 (first patient in) and 12-Apr-2021 (last patient in), 70 pts were screened by 10 German hospitals; 49 pts were registered by 9 sites. A two-stage design (Simon) was used: the first 15 pts were analyzed after 3 months of therapy.

    Pre-assignment
    Screening details
    The patients were selected by the investigator according to the inclusion and exclusion criteria after they had been informed about the study in writing and orally and had signed an informed consent form. The baseline examinations had to be performed within 28 days prior to date of registration.

    Cetuximab was supplied as 20 mL vials with 100 mg Cetuximab (each mL of solution for infusion contained 5 mg). Patients received Cetuximab 500 mg/m² as an intravenous infusion on day 1 every 2 weeks. The recommended infusion period for the first infusion was 180 minutes. The following biweekly infusions were administerd as 120-minute iv infusions with the infusion rate not exceeding 10 mg/min. Dose modifications (reductions or escalations) were not allowed. Doses could be delayed for drug-related AEs until improvement to NCI grade ≤1.

    Objective response rate after 3 months of combination therapy of avelumab and cetuximab according to RECIST v1.1 [1]
    End point description
    Tumor assessments using computed tomography scan or magnetic resonance imaging of chest, abdomen and pelvis as well as of other tumor bearing areas were performed at screening and every 12 weeks during study treatment and during 3-monthly follow-up visits based on the German Guidelines for Diagnosis and Management of cSCC. Clinical assessment of cutaneous tumor lesions, including photography, had to be performed at screening and every 6 weeks during treatment period. Response evaluation was performed by the investigator according to RECIST v1.1 criteria. The overall response rate includd all patients with CR or PR at the respective time point. A non-interesting response rate of p0 = 30% and a target response rate of p1 = 50% were assumed. The hypotheses H0: p ≤ p0 versus H1: p ≥ p1 were tested with a first-type error rate of α = 0.05. At least 19 patients with objective responses (CR + PR) were required in 46 evaluable patients to reject p ≤ p0.
