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   43881   clinical trials with a EudraCT protocol, of which   7295   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.

    General information about the trial
    Main objective of the trial
    • To characterize the safe use of the investigational medicinal product and the transplantation/implantation procedures. • To characterize the cumulative functional and radiographic effects of NDplus over NDbasic and SC. • To characterize the effect of NDbasic alone over SC. • To characterize the effect of the investigational medicinal product on the adjacent de-generative discs. • To define metabolic parameters that measure identity, purity, and potency of the extracted tissue, of the isolated cells, and of the in vitro expanded cells. • To define metabolic parameters in subjects to control the status of tissue repair. • To define metabolic parameters in patients to control the status of tissue repair • To define the prognostic value of metabolic and radiological parameters in the context of disc degeneration, functional status, and quality of life
    Protection of trial subjects
    NDisc plus application: The required biomaterial for the cell culture is extracted in the context of an elective sequestrectomy. The material is taken from the extracted disc and therefore a by-product of the elective sequestrectomy with no additional risk for the patient. Nutrition solution for cultivation of human chondrocytes contains a small amount of homologous serum, which is manufactured by Transfusion Medicine Tuebingen. EU-GMP-guidelines are fully applied. The injection needle for the implantation must be inserted into the remaining disc tissue under the image converter tube (X-ray unit). The administered radiation dose is about the same as that of 2x-ray-chest images. For NDplus and NDbasic patients female patients are required to take contraceptive measures until the end of the therapy phase. Pregnancy tests are performed prior to sequestrectomy and prior implantation. Local anaesthesia prior to implantation were conducted. Investigators are specially trained for the process of implantation.
    Background therapy
    Standard of care treatment: Sequestrectomy
    Evidence for comparator
    NOVOCART® Disc plus (NDplus) was developed to provide rehydration and biological integrity of degenerative lumbar discs to prevent secondary disease such as disc herniation and segmental instability. It was hypothesized that by transplanting disc derived chondrocytes into degenerative discs, where the cells will be held in situ re-differentiate and produce new cartilaginous tissue. Thus patients were expected to experience better outcomes as compared to control (standard care [SC] sequestrectomy). NOVOCART® Disc basic (NDbasic) alone has no active cell component, its hydrophilic characteristics and specific ingredients for influencing cell metabolism and anti-inflammatory as well as anti-angiogenic, anti-osteogenic, and anti-neurotropic milieu conditioning has a potential for disc regeneration and effective pain treatment.
