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   42572   clinical trials with a EudraCT protocol, of which   7010   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.2.2Secondary objectives of the trial
    • To evaluate the effect of givosiran, compared to placebo, on:

    o Urinary porphobilinogen (PBG) levels in patients with AIP
    o Hemin usage in patients with AIP
    o The rate of porphyria attacks requiring hospitalization, urgent healthcare visit, or IV hemin administration at home in patients with any AHP
    o In patients with AIP on the symptoms of pain, nausea, and fatigue
    o In patients with AIP on the Physical Component Summary (PCS) of the 12-item Short-Form Health Survey (SF-12)
    • Evaluate the safety and tolerability of givosiran in patients with any AHP
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Age ≥12 years
    2. Documented diagnosis of AIP, HCP, VP, or ADP based on clinical features (eg, acute attacks of abdominal, back, chest, extremities, and/or limb pain), at least one documented urinary or plasma PBG or ALA value ≥4× upper limit of normal (ULN) within the past year prior to or during Screening, AND one of the following:
    • Documented genetic evidence of mutation in a porphyria-related gene, defined as ANY of the following:
    - AIP: mutation in the hydroxymethylbilane synthase gene (HMBS; also referred to as the porphobilinogen deaminase [PBGD] gene)
    - HCP: mutation in the coproporphyrinogen oxidase (CPOX) gene
    - VP: mutation in the protoporphyrinogen oxidase (PPOX) gene
    - ADP: mutation in the aminolevulinic acid dehydratase (ALAD) homozygous or compound heterozygous genes
    • OR if the results of a patient’s genetic testing do not identify a mutation in a porphyria-related gene (<5% of cases), a patient may be eligible for the study if they have both clinical features and diagnostic biochemical criteria consistent with AHP
    3. Have active disease, with at least 2 porphyria attacks requiring hospitalization, urgent healthcare visit or treatment with IV hemin at home within the 6 months prior to Screening
    4. Willing to discontinue and/or not initiate use of prophylactic hemin at the time of Screening and for the duration of the study
    5. Have adequate venous access for study sample collection as judged by the investigator
    6. Be willing to comply with the contraceptive requirements during the study period
    7. Be willing and able to comply with the study requirements and to provide written informed consent per local and national requirements. In the case of patients under the age of legal consent, legal guardian(s) must provide written informed consent and the patient should provide assent per local and national requirements and institutional standards.
    E.4Principal exclusion criteria
    1. Any of the following laboratory parameter assessments at Screening:
    a. Alanine aminotransferase (ALT) >2×ULN
    b. Total bilirubin >1.5× ULN. Patients with elevated total bilirubin that is secondary to documented Gilbert’s syndrome are eligible if the total bilirubin is <2×ULN
    c. International normalized ratio (INR) > 1.5 (patients on an anticoagulant [eg, warfarin] with an INR< 3.5 will be allowed)
    2. Estimated Glomerular Filtration Rate (eGFR) <30 mL/min/1.73 m2 using the Modification of Diet in Renal Disease (MDRD) formula
    3. On an active liver transplantation waiting list, or anticipated to undergo liver transplantation during the blinded study treatment period

    5. History of intolerance to subcutaneous injection(s)
    6. Known active HIV infection; or evidence of current or chronic hepatitis C virus (HCV) or hepatitis B virus (HBV) infection
    7. Currently enrolled in another investigational device or drug study, or less than 30 days or 5 half-lives (whichever is longer) since ending another investigational device or drug study(s), or receiving other investigational agent(s)
    8. Females who are pregnant, breast-feeding, or planning to become pregnant during the study
    9. Any condition (eg, medical concern or alcohol or substance abuse), which in the opinion of the Investigator, would make the patient unsuitable for dosing or which could interfere with the study compliance, the patient’s safety and/or the patient’s participation in the 6-month treatment period of the study. This includes significant active and poorly controlled (unstable) cardiovascular, neurologic, gastrointestinal, endocrine, renal or psychiatric disorders unrelated to porphyria identified by key laboratory abnormalities or medical history.
    10. History of recurrent pancreatitis, or acute pancreatitis with disease activity within the past 12 months prior to Screening
    11. Has a major surgery planned during the first 6 months of the study
    12. History of serious infection within one month prior to Screening
    13. Had a malignancy within 5 years prior to Screening, except for basal or squamous cell carcinoma of the skin, cervical in-situ carcinoma, or breast ductal carcinoma, that has been successfully treated
