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   44339   clinical trials with a EudraCT protocol, of which   7369   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
    This study will examine the safety and efficacy of once-weekly omarigliptin in participants 18 to <45 years of age with Type 2 diabetes mellitus and inadequate glycemic control. The study hypothesis is that treatment with omarigliptin compared with placebo provides greater reduction in hemoglobin A1c (A1C) in participants after 24 weeks.
    Protection of trial subjects
    This study was conducted in conformance with Good Clinical Practice standards and applicable country and/or local statutes and regulations regarding ethical committee review, informed consent, and the protection of human subjects participating in biomedical research. The following additional measure defined for this individual study was in place for the protection of trial participants: participants exceeding pre-specified glycemic thresholds after Day 1 of the double-blind treatment period were to have rescue therapy with open-label metformin initiated by the investigator.

    		 Change from baseline in A1C at Week 24
    End point description
    A1C (%) is used to report average blood glucose levels over prolonged periods of time. Analysis population: Full analysis set (FAS) population comprised all participants who received at least one dose of study treatment and had a baseline measurement or a post-randomization measurement for the analysis endpoint. The unexpected absence of a treatment effect in this study led to investigations that included measurement of metformin levels in available samples collected for future research during the study. Of the 92 participants with samples who had not been rescued with metformin, 57% (25/44) in the placebo group and 29% (14/48) in the omarigliptin group had detectable metformin, indicating the use of metformin that was prohibited by the protocol. The use of metformin prohibited by the protocol was without investigator knowledge and is a confounding factor impacting the ability to draw any conclusions regarding the efficacy results from this study.

    An AE is defined as any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it is considered related to the medical treatment or procedure, that occurs during the course of the study. Data presented exclude data following the initiation of glycemic rescue. Analysis population: All participants treated (APaT) population included all randomized participants who received at least one dose of study medication. The safety database was analyzed in a standard fashion in the APaT population for all participants who took at least one dose of study medication. This analysis may have been confounded by the use of metformin prohibited by the protocol (see efficacy results description above).

    End point title
    		 Percentage of participants who required glycemic rescue by Week 24
    End point description
    Participants exceeding pre-specified glycemic thresholds after starting the double-blind treatment period may have received rescue therapy (per protocol) with open-label metformin initiated by the investigator. Analysis population: all randomized participants. This analysis may have been confounded by the use of metformin prohibited by the protocol (see efficacy results description above).

    Adverse events information
    Timeframe for reporting adverse events
    Up to 27 weeks; Serious adverse events (SAEs) were collected up to 24 weeks during treatment + 3 week follow-up, non-serious adverse events (NSAEs) were collected up to 24 weeks during treatment
    Adverse event reporting additional description
    SAEs include data after glycemic rescue; NSAEs exclude data after glycemic rescue. Investigations performed by the Sponsor revealed that many participants had used a prohibited antihyperglycemic agent—metformin (i.e., not as rescue medication; see efficacy results description above).

    Limitations and caveats
    Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data.
    Investigations indicate that the presence of metformin in future biomedical research (FBR) samples from non-rescued participants was due to participant self-administration of metformin outside of the protocol and without investigator knowledge.
