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
    To investigate the efficacy, safety, and tolerability of linagliptin 5 mg once daily compared with placebo as add-on therapy for 24 weeks to stable basal insulin treatment in elderly (≥60 years) patients with type 2 diabetes mellitus and insufficient glycaemic control.
    Protection of trial subjects
    Safety was to be ensured by monitoring the patients for AEs clinically, by laboratory testing, and by home blood glucose monitoring (HBGM). Patients who were not adequately controlled could have their permitted background medication adjusted or new antidiabetic medications introduced to ensure their safety. In case the patient developed any condition/disease or AE which did not allow – according to investigator’s judgement – the patient’s safe continuation of the trial, the patient was to be prematurely discontinued from the trial. Symptoms that could be attributed to hypoglycaemia were to be closely monitored during the trial. General risks associated with participating in this trial were related to trial-specific procedures such as blood sampling. The amount of blood taken during the whole course of the trial was considered to be of no or negligible risk to the patients. The trial design with a 1-week placebo run-in phase is a well-established design for trials in type 2 diabetes. Daily monitoring of blood glucose was performed by patients with the HBGM device and patients were to be discontinued if there was any indication that the patient was not stable enough. Thus the risk of the 1-week placebo treatment was minimal.

    Recruitment
    Recruitment details
    		 This was randomised, double blinded, placebo controlled, parallel study. Total 525 patients with type 2 diabetes mellitus (T2DM) and insufficient glycaemic control were screened. 302 patients were randomised into two groups. The trial was extended to 52 weeks for Japanese patients. 102 patients were identified and observed for the extended period.

    Pre-assignment
    Screening details
    		 All patients were screened for eligibility to participate in the trial. Subjects attended specialist sites which would then ensure that they (the subject) met all strictly implemented inclusion/exclusion criteria. Subjects were not to be randomised to trial treatment if any one of the specific entry criteria were violated.

    Hemoglobin A1c (HbA1c) at baseline
    HbA1c values measured at baseline in percent. HbA1c is a form of hemoglobin, a blood pigment that carries oxygen, which is bound to glucose. The term HbA1c also refers to glycated hemoglobin. High levels of HbA1c (Normal range is less than 6%) indicate poorer control of diabetes than level in normal range.

    End point description
    This outcome has measured difference between HbA1c values from baseline to 24 weeks post treatment. The term ‘baseline’ refers to the last observation prior to the administration of any randomised study medication. HbA1c is a form of hemoglobin, a blood pigment that carries oxygen, which is bound to glucose. The term HbA1c also refers to glycated hemoglobin. High levels of HbA1c (Normal range is less than 6%) indicate poorer control of diabetes than level in normal range. Population set used for analysis: Full analysis set observed cases (FAS (OC)): Includes all patients randomised in the Treated Set who had a baseline and at least one on-treatment HbA1c value. These analyses used available data as observed while patients were on treatment. All values collected after a patient started rescue medication were excluded from the analysis.

    		 Percentage of patients experiencing at least one hypoglycaemia accompanied by a prespecified glucose value.
    End point description
    Hypoglycaemia accompanied by a prespecified glucose value is defined as any investigator reported hypoglycaemia (event or AE) with a reported blood glucose level of less than 54 milligram/deciLitre (3.0 millimole/Litre) or any investigator reported symptomatic hypoglycaemic AE with a reported blood glucose level of less or equal 70 milligram/deciLitre (3.9millimole/Litre) or any severe hypoglycaemic AE. Severe hypoglycaemia is an event that requires the assistance of another person to actively administer carbohydrates or glucagon because the patient is unable to take the substance on his or her own. The confidence intervals mentioned in measure of dispersion are exact 95% confidence interval by Clopper and Pearson. The proportion of patients with at least one hypoglycaemia accompanied by a glucose value less than 54mg/dL alone has also represented separately according to American Diabetes Association definition of clinically significant hypoglycaemia.

    Statistical analysis description
    A logistic regression model with treatment as fixed effect and baseline HbA1c and baseline daily basal insulin dose as linear covariates was applied. This analysis showed that patients teated with linagliptin were more likely to achieve these responses than in the placebo group.The dispersion value standard error of the mean is actually standard error for odds ratio.

    End point description
    This is the proportion of patients with HbA1c on treatment <7.0% after 24 weeks of treatment. The confidence intervals mentioned in method of dispersion are exact 95% CI by Clopper and Pearson. Population set used for analysis: Full analysis set (Non-completers considered failure)(FAS (NCF)): Includes all patients randomised in the Treated Set who had a baseline and at least one on-treatment HbA1c value. This analyses regarded missing values for binary efficacy endpoints as failure.

    End point description
    This outcome has measured difference between FPG values from baseline to 24 weeks post treatment. The term ‘baseline’ refers to the last observation prior to the administration of any randomised study medication. Population set used for analysis: Full analysis set observed cases (FAS (OC)): Includes all patients randomised in the Treated Set who had a baseline and at least one on-treatment HbA1c value. These analyses used available data as observed while patients were on treatment. All values collected after a patient started rescue medication were excluded from the analysis.

    Timeframe for reporting adverse events
    From first drug administration up to 24 weeks, until 7 days after last drug administration for overall population. And from first drug administration up to 52 weeks, until 7 days after last drug administration for Japanese population.
    Adverse event reporting additional description
    An AE was defined as any untoward medical occurrence, including an exacerbation of a preexisting condition, in a patient in a clinical investigation who received a pharmaceutical product. A treated set (TS) was used for AE analysis. TS includes patients who were dispensed study medication and taken at least one dose of investigational treatment.
