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   44335   clinical trials with a EudraCT protocol, of which   7366   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 ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    To demonstrate that the combination of palbociclib with cetuximab is superior to cetuximab in prolonging Overall Survival in HPV-negative, cetuximab-naïve patients with Recurrent/Metastatic Squamous Cell Carcinoma Of The Head and Neck in whom one prior platinum-containing chemotherapy has failed.
    Demostrar que la combinación de palbociclib con cetuximab es superior al cetuximab en la prolongación de la SG en pacientes con CCECC recurrente/metastásico VPH negativos, sin tratamiento previo con cetuximab, en los que fracasó la quimioterapia previa con platino.
    E.2.2Secondary objectives of the trial
    -To compare secondary measure of efficacy between the treatment arms;
    -To compare safety and tolerability between the treatment arms;
    -To compare Patient-Reported Outcome (PRO) measures between the treatment arms;
    -To characterize the correlations between baseline biomarker (eg, p16, Rb) expression in tumor tissue and clinical efficacy in both treatment arms;
    -To characterize steady state trough concentrations for palbociclib, and trough and maximum concentrations for cetuximib in patients with Recurrent/Metastatic Squamous Cell Carcinoma Of The Head and Neck.
    - Comparar la variable secundaria de la eficacia entre los grupos de tratamiento.
    - Comparar la seguridad y la tolerabilidad entre los grupos de tratamiento.
    - Comparar los resultados notificados por los pacientes (PRO) entre los grupos de tratamiento.
    - Caracterizar las correlaciones entre la expresión basal de biomarcadores (p. ej., p16, Rb) en el tejido tumoral y la eficacia clínica en ambos grupos de tratamiento.
    - Caracterizar las concentraciones mínimas en estado estacionario de palbociclib, y las concentraciones mínimas y máximas de cetuximab en los pacientes con CCECC recurrente/metastásico.
    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    Optional pharmacogenomic sub-study using banked biospeciments for the following research:
    - Investigations of the disease under study in the clinical study, and related conditions;
    - Biospecimens may be used as controls. This includes use in case-control studies of diseases for which Pfizer is researching drug therapies; use in characterizing the natural variation among people in genes, RNA, proteins, and metabolites; and use in developing new technologies related to pharmacogenomics/biomarkers.
    Sub-estudio farmacogenómico opcional que utiliza las muestras biológicas para depósito en banco para las siguientes investigaciones:
    - Investigaciones sobre la enfermedad que se está evaluando en el estudio clínico y sobre afecciones relacionadas.
    - Las muestras biológicas pueden emplearse como controles. Esto incluye el uso en estudios de casos y control de enfermedades para las cuales Pfizer esté investigando farmacoterapias; el uso en la caracterización de la variación natural entre las personas con respecto a genes, ARN, proteínas y metabolitos; y el uso en el desarrollo de nuevas tecnologías relacionadas con la farmacogenómica/los biomarcadores.
    E.3Principal inclusion criteria
    1. Histologically or cytologically confirmed squamous cell carcinoma of the oral cavity, oropharynx, hypopharynx or larynx, not amenable for salvage surgery or radiotherapy.
    2. Measuarable disease as defined per RECIST v. 1.1. Tumor lesions previously irradiated or subjected to other locoregional therapy will only be deemed measureable if disease progression at the treated site after completion of therapy is clearly documented.
    3. HPV-negative SCCHN tumor as determined per institutional standard (eg, p16 IHC; multiplex nucleic acid sequence based amplification [NASBA] or other polymerase chain reaction [PCR]-based assays).
    4. Documented progressive disease according to RECIST v1.1 following
    receipt of at least 2 cycles of one platinum-containing chemotherapy regimen administered for R/M disease (min. 50 mg/m2 for cisplatin, minimum area under the curve [AUC] >4 for carboplatin).
    5. Availability of a tumor tissue specimen (ie, archived formalin fixed paraffin embedded tissue [block preferred, or 15 unstained slides]), which will be used for centralized, retrospective biomarker analysis. If archived tumor tissue is not available, then a de novo biopsy will be required for patient participation.
    6. ECOG performance status (PS) 0 or 1.
    7. Adequate organ and marrow function defined as follows:
    - Leukocytes >3,000/mm3 (3.0 x 1.000.000.000/L);
    - Absolute Neutrophil count (ANC) ? 1,200/mm3 (1.2 x 1.000.000.000/L);
    - Platelets ? 75,000/mm3 (75 x 1.000.000.000/L);
    - Hemoglobin (Hb) ? 9 g/dL (90 g/L);
    - Serum creatinine ? 1.5 x upper limit of normal (ULN) or estimated creatinine clearance ? 40 mL/min as calculated using the method standard for the institution;
    - Total serum bilirubin ? 1.5 x ULN (? 3.0 x ULN if Gilbert's disease);
    - Asparate aminotransferase (AST) and/or alanine aminotransferase (ALT) ? 2 x ULN (? 5.0 x ULN if liver metastases present);
    - Alkaline phosphatase ? 2.5 x ULN (? 5.0 x ULN if bone or liver metastases present).
    8. Male and female patients of childbearing potential and at risk for pregnancy must agree to use two highly effective methods of contraception throughout the study and for 6 months after the last dose of cetuximab.
    Female subjects who are not of childbearing potential (ie, meet at least 1 of the following criteria):
    - Have undergone a documented hysterectomy and/or bilateral oophorectomy;
    - Have medically confirmed ovarian failure; or
    - Achieved postmenopausal status, defined as follows: cessation of regular menses for at least 12 consecutive months with no alternative pathological or physiological cause; status may be confirmed by having a serum follicle stimulating hormone (FSH) level within the laboratory?s reference range for postmenopausal women.
    9. Age ? 18 years (or ? 20 years as applicable by local country regulations).
