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 ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    6. Non ambulatory patients must be able to sit independently (sits up straight with head erect for at least 10 seconds; does not use arms or hands to balance body or support position) per World Health Organization (WHO) motor milestones definition at screening. Patients who never had the ability to walk independently will be classified as Type 2. Patients who previously had the ability to walk unaided will be classified as Type 3.
    7. Ambulatory patients must have the ability to independently ambulate without aids or orthotics over 10 meters in 30 seconds or less at screening
    8. For Cohort 1, Revised Hammersmith Scale (RHS) score no greater than 63 at screening
    9. For Cohorts 2 and 3, Hammersmith Functional Motor Scale Expanded (HFMSE) score no less than 10 at screening
    10. Receiving the same background SMA therapy (e.g., on an approved survival motor neuron (SMN) upregulator therapy such as nusinersen, or not on any SMA therapy) for at least 6 months prior to screening and anticipated to remain on that therapy throughout the duration of the study
    10a. If receiving the SMN upregulator therapy nusinersen, must have completed the loading regimen and initiated maintenance dosing (i.e., completed at least one maintenance dose) with at least 4 weeks after the first maintenance dose having elapsed prior to screening
    11. Nutritional status stable over the past 6 months and anticipated to be stable throughout the duration of the study
    12. Have no physical limitations that would prevent the patient from undergoing motor function outcome measures throughout the duration of the study
    13. Able to receive study drug infusions and provide blood samples through the use of a peripheral intravenous (IV) or a long-term IV access device that the patient has placed for reasons independent from the study (i.e., for background medical care and not for the purpose of receiving SRK-015 in the study), throughout the duration of the study
    14. Able to adhere to the requirements of the protocol, including travel to the study center and completing all study procedures and study visits
    15. For patients who are expected to have reached reproductive maturity by the end of the study, adhere to study specific contraception requirements
    15a. Females of childbearing potential must have a negative pregnancy test at screening and agree to employ highly effective contraceptive measures (failure rate of 1% or less per year when used consistently and correctly) for the duration of the study and for 12 weeks following the last dose of study drug. Effective contraception methods are restricted to abstinence, intrauterine contraceptive devices, bilateral tubal occlusion, vasectomized partner, or a licensed hormonal product in combination with a barrier method.
    15b. Male patients with female partners of childbearing potential must be abstinent or agree to employ the use of a condom with or without spermicide throughout the duration of the study and for 12 weeks following the last dose of study drug.
    E.4Principal exclusion criteria

    3. Any acute or co morbid condition interfering with the well being of the patient within 14 days of screening, including active systemic infection, the need for acute treatment or inpatient observation due to any reason
    4. Severe scoliosis and/or contractures at screening. Based on clinical judgement, any scoliosis or contractures present must be stable over the past 6 months, anticipated to be stable for the duration of the study and not prevent the patient from being evaluated on any functional outcome measures throughout the duration of the study.
    5. Pregnant or breastfeeding
    6.

    11. Patient has any other condition, which in the opinion of the Investigator may compromise safety or compliance, would preclude the patient from successful completion of the study, or interfere with the interpretation of the results
