Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   42556   clinical trials with a EudraCT protocol, of which   7007   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    To evaluate the safety and the efficacy i.e., complete almost complete cutaneous re-epithelialization at D7 after infusion of 2×106/kg ASCs in SJS-TEN patients. Indeed, usual mean time to epithelialization is 14 days, thus, considering the results of the survey about MCID described above, we decided to evaluate the rate of complete or almost complete healing at D7 post-infusion (i.e 10 days after inclusion).
    E.2.2Secondary objectives of the trial
    To evaluate the impact of ASCs treatment on SJS-TEN clinical course and immunological markers.

    E.5 End points
    E.5.1Primary end point(s)
    Safety :
    The toxicity is defined as the observation of at least one of the following adverse events:
    - Persisting fever (> 38.5°C between D5 and D10) independently of a sepsis
    - Local acute infusional toxicity: phlebitis, hematoma, local infection between D0 and D3
    - Anaphylaxis or severe systemic reaction following ASCs administration at D0
    - Rash between D0 and D3, involving ≥30% of BSA
    - Cardiac complications in absence of previous cardiologic disease between D0 and D3
    - Sustained ventricular arrhythmia between D0 and D3
    - ST-elevation myocardial infarction between D0 and D3
    - Acute pulmonary edema with PaO2 < 60 mm Hg or signs of congestion (RR> 25, laboured breathing, cyanosis, dyspnoea NYHA Grade IV) in absence of infectious pneumopathy and specific SJS-TEN lung involvement between D0 and D3
    - Cardiogenic shock with signs of hypoperfusion between D0 and D3
    - Thrombo-embolic event between D0 and D3
    - Cerebral infarction between D0 and D3
    - Acute renal failure or doubling of creatinine between D0 and D3
    - Epilepsia between D0 and D3
    - Sepsis between D0 and D3
    - Death between D0 and D3

    If one of these outcome is observed, then it will be considered as a toxicity for the patient.

    Efficacy:
    The efficacy is defined as the cutaneous re-epithelialization at D7 post-infusion according to the percentage of cutaneous BSA re-epithelialized in comparison to maximal cutaneous detachable-detached BSA observed previous or after infusion.

    Complete response, almost complete response : At least 90% of detached-detachable cutaneous BSA re-epithelialized.
    Partial response : Between 50% and 90% of detached-detachable cutaneous BSA re-epithelialized.
    Failure : Less than 50% of detached-detachable cutaneous BSA re-epithelialized.

    For simplicity, regarding the small sample size of the trial, complete (or almost complete) response and partial response will be considered as procedure success. In case of patient’s death, his(her) response will be considered as a failure of the procedure.
    Cutaneous detachable-detached BSA will be assessed according to the international standardized Wallace rule of Nines: 9% of body surface area involved is given for involvement of the head, each arm, chest and abdomen, 18% for each leg and the back, and 1% for the groin. Also the patient's palm can serve a reference point roughly equivalent to 1% of the body surface area for total assessment.
