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   44334   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 ).

    		 Change from baseline in Kansas-City Cardiomyopathy Questionnaire-Total Symptom Score (KCCQ-TSS) at week 16 (higher scores represent less HF symptom frequency and burden).
    End point description
    Change from baseline in KCCQ-TSS was defined as the endpoint value at week 16 minus the baseline value. KCCQ is a 23-item, self-administered instrument that quantifies physical function, symptoms (frequency, severity and recent change), social function, self-efficacy and knowledge, and quality of life. The KCCQ-TSS incorporates the symptom frequency (4 items) and symptom burden (3 items) domains into a single summary score. The score is transformed to a range of 0-100, in which a higher score reflects better health status. Baseline value is the last value on or prior to the randomisation visit. Deaths are treated as the worst outcome and ordering among deaths is based on last value while alive. In rank ANCOVA and HL estimation, multiple imputation was performed on missing values for patients who were alive at the visit at week 16 but did not have KCCQ-TSS values.

    Substantial protocol amendments (globally)
    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    04 Mar 2020
    The main purpose of this amendment was to add 2 primary objectives to the study (ie, reduction in HF symptoms and reduction in physical limitation). The primary objectives are now to determine whether dapagliflozin is superior to placebo in reducing heart failure symptoms, reducing physical limitation, or improving exercise capacity in patients with chronic heart failure. The family of primary endpoints are KCCQ-TSS, KCCQ-PLS, and 6MWD. Some secondary objectives became exploratory objectives and other exploratory endpoints were revised. Clarifications were also made to text unrelated to the endpoints. The following details the key changes: Section 1.2 (Synopsis): Updated to reflect changes in the CSP text, including the changes to the objectives/endpoints as detailed in Section 3. Section 2: (INTRODUCTION) Updated to reflect changes in the objectives/endpoints as detailed in Section 3. Section 3 (OBJECTIVES AND ENDPOINTS): Two additional primary efficacy objectives/endpoints were added (ie, KCCQ-TSS and KCCQ-PLS) to create a primary endpoint family. Some secondary objectives became exploratory and certain exploratory objectives/endpoints were reordered and rephrased. Section 4 (STUDY DESIGN): Updated to reflect changes in the objectives/endpoints as detailed in Section 3. Explanation/clarification was added for the choice of primary endpoints. Section 6.3.1.2 (Capping): Updated to allow it on a level lower than the whole study. Section 7.4 (Discontinuation of the study): Reasons for the early closure of the study site were added as per more recent protocol template. Section 8.1 (Efficacy assessments): Updated to reflect changes in the objectives/endpoints as detailed in Section 3. Section 9 (STATISTICAL CONSIDERATIONS): Updated to reflect changes in the objectives/endpoints as detailed in Section 3, including updated power calculations and methodology for type I error control. General:Minor editing corrections to improve clarity and consistency.

    Limitations and caveats
    Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data.
    Data collection from the wearable device worn by a subset of patients at home for 3 periods of 7 days was challenging and a substantial amount of data was missing. This limits the use of the data based on the wearable activity monitors.
