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   43801   clinical trials with a EudraCT protocol, of which   7272   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.

    signed and dated informed consent and authorization to use protected
    health information (PHI) in accordance with national and local privacy

    GAA genetic testing) of LOPD, or based on a documented deficiency of
    GAA enzyme activity;
    3. Have received a marketed ERT for at least the previous 24 months and

    b. Percentage of the predicted FVC ≥30% and ≤80% in the upright
    5. Agree to use reliable contraception for a minimum of 6 months after
    administration of SPK-3006 or 12 weeks after the final dose of sirolimus,
    whichever occurs later. Female candidates of child-bearing potential
    must have a negative pregnancy test prior to initiating
    immunosuppression (Day -6) and on Day 0 prior to administration of
    SPK-3006. See Section 13 (Appendix 1) for guidance on reliable
    contraception and the definition of women of child-bearing potential
    6. Agree to refrain from blood, plasma, platelets, egg or sperm and organ

    E.4Principal exclusion criteria
    1. Active hepatitis B and/or C
    All candidates must be screened for both active hepatitis B and C,
    regardless of prior known history.
    a. Screening for hepatitis B
    All candidates must have a single sample at Screening for each of the
    following tests: hepatitis B surface antigen (HBsAg), total hepatitis B
    core antibody (anti-HBc), and a nucleic acid test for hepatitis B virus
    DNA (HBV-DNA viral assay)
    i. A candidate is not eligible if either HBsAg is positive or HBV-DNA is
    ii. A candidate is eligible if the anti-HBc is positive and both HBsAg and
    HBV-DNA are negative, as this would be consistent with a prior infection
    of hepatitis B. Anti-HBc must be obtained in all candidates to
    discriminate between acute infection and possible reactivation of
    hepatitis B during the trial in candidates with no prior history of
    hepatitis B.
    iii. A candidate who is currently undergoing antiviral therapy for chronic
    hepatitis B is not eligible.
    b. Screening for hepatitis C
    i. A candidate who is currently undergoing antiviral therapy for chronic
    hepatitis C is not eligible.
    ii. All other candidates, including those who have never been treated or
    who have completed antiviral therapy for chronic hepatitis C must have a
    nucleic acid test for hepatitis C viral RNA (HCV-RNA single load assay) at
    • A candidate is not eligible if the HCV-RNA load assay is
    • Candidates treated with anti-viral therapy for chronic hepatitis C, must
    have completed anti-viral therapy at least 6 months prior to Screening
    and have a negative HCV-RNA at Screening.
    • Candidates with a documented or self-reported history of hepatitis C
    must have a single negative HCV-RNA at Screening
    2. Significant underlying liver disease. A candidate is not eligible if any
    of the following pre-existing diagnoses, which are indicative of
    significant underlying liver disease, are present in the medical record
    • Liver cirrhosis
    • Portal hypertension
    • Hepatic encephalopathy
    • Gamma-glutamyl transferase (GGT) >1.2X ULN adjusted for age and
    gender; or
    • Bilirubin >1.2X ULN adjusted for age and gender. Candidates with
    asymptomatic elevated bilirubin (e.g., Gilbert syndrome) can be
    considered after discussion with the Medical Monitor.
    All candidates who do not have the pre-existing diagnoses listed above
    must have the following assessments performed at Screening
    • Measurement of serum albumin. A candidate is not eligible if the serum
    albumin level is below the testing laboratory's lower limit of normal
    • Liver fibrosis = stage 3. The following results are indicative of fibrosis
    >= stage 3 and exclude the candidate from participation
    - FibroScan, with a score > 8.3 kPa units
    - FibroTest/ FibroSURE with a result > 0.48
    - AST-Platelet Ratio Index (APRI) >1;
    Of note, if results from more than one modality for evaluation of liver
    fibrosis are available (e.g., results from both FibroScan and FibroSURE
    are available) the result from FibroScan should be consulted for
    determination of liver fibrosis as it will take precedence over other
    3. Human immunodeficiency virus (HIV) infection
    4. Prior hypersensitivity to rhGAA
    5. Pre-existing AAV-Spark100 neutralizing antibody titers >1:1
    6. High titer antibody responses to rhGAA (anti-GAA >1:30,000)
    7. Participation in a clinical study with an investigational drug in the past
    6 months (vaccination studies are accepted; observation studies are
    accepted after discussion with the Medical Monitor);
    8. Requires any invasive ventilation or requires noninvasive ventilation
    while awake and upright;
    9. Any change to respiratory muscle strength training within 90 days
    prior to informed consent (for participants receiving respiratory muscle
    strength training) or initiation of respiratory muscle strength training
    prior to Day 0
    10. Received any prior vector or gene transfer agent
    11. Concomitant use of medication that is contraindicated with sirolimus
    (see Section, such as, medication known to be a strong or
    moderate inducer or inhibitor of CYP3A4 – excluded only during the
    sirolimus immunosuppressive period
    12. Live vaccines within 30 days prior to informed consent to at least 52
    weeks after receiving SPK-3006 infusion
    13. Use of systemic immunosuppressive agents (e.g., corticosteroids)
    within 30 days prior to informed consent and to Day 0 prior to SPK-3006
    14. Active malignancy (except non-melanoma skin cancer)
    15. History of liver cancer
    16. Pregnant or nursing women
    17. Any evidence of an active infection at the time of SPK-3006 infusion
    18. Known allergy or hypersensitivity to SPK-3006 investigational

    the potential participant to complete the follow-up examinations during
    the course of the study, or other condition that, in the opinion of the
    Investigator and/or Medical Monitor, and/or Sponsor makes the
    candidate unsuitable for participation in the study
