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   43851   clinical trials with a EudraCT protocol, of which   7283   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 ).

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    17 Jun 2013
    1. Included subjects who had evidence of both EGFR -activating mutations (exon 19 deletion and L858R mutation in exon 21) within a tumor specimen (allowing for the presence of the T790M mutation in exon 20). 2. Updated emerging information on dacomitinib PK characteristics and metabolism in subjects and implemented related changes in the dosing instructions and concomitant medications; 3. Provided instructions for preparation of tumor tissue specimens for EGFR mutational analysis and pathology/histology study to ensure that sufficient tumor specimens would be available for protocol-required testing; clarified that confirmation of adenocarcinoma histology and presence of an EGFR-activating mutation in tumor tissue were required for eligibility screening; 4. Stated that CYP2D6 genotyping would be performed in patients treated in the dacomitinib arm who were undergoing multiple PK sampling on C2D1; 5. Stated that dacomitinib could be dosed with or without food; added that concomitant use of proton-pump inhibitors and H 2 antagonists with dacomitinib should be avoided if possible; 6. Clarified that potential dose reductions to manage treatment-related toxicity applied only to dacomitinib (not gefitinib); added guidelines for interruption and resumption of gefitinib dosing for management of toxicity.
    01 Oct 2013
    Expanded eligibility to subjects with recurrent NSCLC (in addition to those with newly diagnosed disease), if there was a disease-free interval of at least 12 months’ duration between completion of prior systemic therapy (neoadjuvant/adjuvant chemotherapy and/or combined modality chemotherapy/radiation therapy) and recurrence of NSCLC.
    30 Jun 2014
    1. Removed the planned IA of PFS and modified related statistical considerations; 2. Shortened the period from screening to randomization in China; required confirmation of adenocarcinoma histo- and/or cytopathology, by the local laboratory prior to screening for all patients; 3. Added statement that a tumor specimen must be available for retrospective central laboratory confirmation for EGFR mutation (ex-China) and adenocarcinoma (all); 4. Clarified conditions for discontinuation of study treatment; 5. Clarified that patients who had PD confirmed by IRC review, and for whom the investigator believed it was in their best interest to continue on their respective study therapy, would be allowed to continue on their respective study therapy; 6. Implemented retrospective CYP2D6 genotyping for all patients treated in the dacomitinib arm; 7. Provided further guidance on treatment and management of common AEs; 8. Clarified follow-up procedures for subjects who continued on their respective study therapy after disease progression assessed by IRC review; specified that long-term follow-up for all subejcts was to include survival status and subsequent cancer therapies; 9. Clarified inclusion criterion: In the case of subjects with recurrent NSCLC who had received prior neoadjuvant/adjuvant chemotherapy, the tumor specimen was to be obtained at the time of recurrence after completion of neoadjuvant/adjuvant therapy.
    30 Jun 2015
    1. Extended the maximum duration of study participation (including long-term follow-up for progression and survival) to 48 months from date of first dose of study treatment per the current protocol (changed from 32 months), to improve the potential to obtain at least 201 overall survival (OS) events; 2. Clarified that no IA was planned for the primary endpoint; 3. Added language describing when and how the analysis of the primary endpoint was to be conducted; 4. Added language describing when and how an interim and a final analysis of the secondary endpoint of OS was to be conducted.
    08 Feb 2018
    1. Study design was clarified to indicate that dacomitinib patients treated for 48 months may continue dacomitinib treatment beyond 48 months through either the Pfizer compassionate use program, transfer onto a local rollover study (applies to patients in Japan only), or through continuation of dacomitinib on this study (applies to patients in China only), if allowed under local law, until disease progression, or unacceptable toxicity, or the study was terminated by Sponsor, whichever occurred first. 2. Study procedures, schedule of activities, and safety/efficacy assessments were added or amended to include patients who will be treated on dacomitinib beyond 48 months.
