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   44359   clinical trials with a EudraCT protocol, of which   7384   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
    The purpose of this study is to determine the efficacy and safety of pembrolizumab given concomitantly with chemoradiation (CRT) and as maintenance therapy versus placebo plus CRT in participants with locally advanced head and neck squamous cell carcinoma (LA HNSCC). The primary hypothesis is that pembrolizumab in combination with CRT is superior to placebo in combination with CRT with respect to event-free survival (EFS).

    Arm description
    On Cycle 1 Day 1 (each cycle is 21 days), participants received a priming dose of 200 mg Pembrolizumab followed by 100 mg/m^2 Cisplatin PLUS 70 Gray (Gy) Radiotherapy (accelerated (AFX) or standard fractionation radiotherapy (SFX)) on Day 8 of Cycles 1, 2 and Cycle 3 (SFX RT regimen only). During CRT, participants received 2 doses of pembrolizumab (Day 1 of Cycles 2 and 3) and up to 3 cycles of Cisplatin (2 cycles during AFX and 3 cycles during SFX RT). Participants also received up to an additional 14 cycles of pembrolizumab alone as maintenance therapy for a total of 17 cycles of pembrolizumab (approximately 1 year). If cisplatin and/or radiation therapy was discontinued, the participant may continue on treatment with pembrolizumab.

    Event-free Survival (EFS)
    End point description
    EFS is the time from date of randomization to the date of first record of any of the following events: death due to any cause; progression per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) by blinded independent central review (BICR) or biopsy as indicated for locoregional progression or recurrence or distant metastasis. As well as the first record of the following types of surgery: salvage surgery for persistent or residual disease at the primary tumor site requiring surgical removal when invasive cancer is present on final pathology; neck dissection or surgery (performed for clinical or radiological disease progression per RECIST 1.1) ≤ 20 weeks from end of CRT when invasive cancer is present; or neck dissection or surgery >20 weeks from end of CRT when invasive cancer is present. A value of 9999 indicates median and upper limit not reached due to insufficient number of participants with an event. Analysis population consists of all randomized participants.

    OS was defined as the time from the date of randomization to the date of death due to any cause. Participants without documented death at the time of analysis were censored at the date the participant was last known to be alive. The non-parametric Kaplan-Meier method was used to estimate the survival curve in each treatment group.

    An AE was defined as any untoward medical occurrence in a participant administered study drug and which does not necessarily have to have a causal relationship with the study drug. An AE is any sign, symptom, disease, or worsening of preexisting condition temporally associated with study therapy and irrespective of causality to study therapy. The number of participants who experienced an AE is presented. Analysis population consists of all randomized participants who received at least one dose of study treatment.

    End point description
    The EORTC QLQ-C30 is a 30-item questionnaire developed to assess the quality of life (QoL) of cancer patients. For Global Health Status (GHS) (Item 29), participants are asked "How would you rate your overall health during the past week?" Individual items are scored on a 7-point (1=very poor to 7=excellent). Raw scores for each scale are standardized into a range of 0 to 100 by linear transformation, with a higher score indicating a better level of function and better overall GHS. A change from baseline of 10 points on the 100-point EORTC QLQ-C30 scale is considered as clinically relevant. Analysis population consists of participants with at least one patient reported outcome (PRO) assessment available for this specific endpoint and who had received at least 1 dose of study intervention.

    End point description
    EORTC QLQ Head and Neck Questionnaire (H&N35) measures QoL in head and neck cancer (HNC) patients. It consists of 7 multi-item scales (pain in the mouth, problems with swallowing, senses, speech, social eating, social contact, and sexuality). Participant responses to the swallowing scale (Items 35-38) were scored on a 4-point scale (1=Not at all to 4=Very much). Raw scores were standardized by linear transformation so that scores ranged from 0 to 100, with a higher score indicating more problems. Change from baseline in swallowing was measured. A change from baseline of 10 points on the 100-point EORTC QLQ-H&N35 is considered as clinically relevant. Analysis population consists of participants with at least one PRO assessment available for this specific endpoint and who had received at least 1 dose of study intervention.

    End point description
    An AE was defined as any untoward medical occurrence in a participant administered study drug and which does not necessarily have to have a causal relationship with the study drug. An AE is any sign, symptom, disease, or worsening of preexisting condition temporally associated with study therapy and irrespective of causality to study therapy. The number of participants who discontinued study drug due to an AE is presented. Analysis population consists of all randomized participants who received at least one dose of study treatment.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    26 May 2017
    AM2: Revision of retropharyngeal (RT) dose parameters to ensure standardization and uniformity of treatment for study while providing flexibility for global radiation therapy practices.
    26 Apr 2018
    AM4: Updated guidelines for dose modification to align with the most current label and safety information for pembrolizumab.
    30 Sep 2019
    AM6: 1) To align the protocol-specified criteria for locoregional failure with the definition of an event considering that protocol- specified locoregional failures are also clinically significant events. 2) Events in patients with locally advanced head and neck squamous cell carcinoma (SCC) treated with definitive chemoradiation therapy (CRT) can occur in the absence of radiographic progression per Response Evaluation Criteria in Solid Tumors (RECIST 1.1) by Blinded Independent Central Review (BICR). Therefore, the Event Free Survival (EFS) definition is being revised accordingly to clarify the scenarios in which histological confirmation of invasive cancer secondary to residual and/or progressive disease fulfills criteria for an event in the absence of radiographic progression per RECIST 1.1 by BICR.
    16 Dec 2020
    AM7: 1) To update the assumptions of the survival distribution of the control arm based on emerging data from JAVELIN 100; and to update the timing of efficacy analysis to allow for additional follow-up of all subjects. 2) To allow imaging assessments to continue for subjects who have not experienced an event. Censoring rules have been changed accordingly. 3) Collection of Fludeoxyglucose Positron Emission Tomography (FDG-PET) reports and corresponding imaging (Computed Tomography (CT)/Magnetic Resonance Imaging (MRI)) reports to fulfill a regulatory request.
    21 Nov 2022
    AM8: Merck Sharp & Dohme Corp. underwent an entity name and address change to Merck Sharp & Dohme LLC, Rahway, NJ, USA. This conversion resulted only in an entity name change and update to the address. Additionally, scheduled trial assessments/procedures were modified based on the results of the final efficacy analysis.
