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   43973   clinical trials with a EudraCT protocol, of which   7311   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.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The aim of this study is to evaluate the efficacy of ancrod treatment on hearing ability in patients suffering from SSHL.
    The primary objective of this study is to determine the efficacy of ancrod as primary treatment of SSHL compared to placebo in patients with unilateral sudden sensorineural hearing loss as determined by audiometry.
    E.2.2Secondary objectives of the trial
    The secondary objectives of this study are to evaluate:
    − The relationship between biomarkers and clinical efficacy.
    − The safety and tolerability of ancrod.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    Patients must meet all of the following inclusion criteria in order to be eligible for this study:
    1. Unilateral idiopathic sudden sensorineural hearing loss ≥30 dB in at least 2 consecutive frequencies in the affected ear or ≥20 dB in 3 consecutive frequencies based upon evaluation of 8 frequencies, 0.125, 0.25, 0.5, 1, 2, 4, 6, and 8 kHz, compared to the contralateral ear.
    2. Symmetric hearing prior to onset of SSHL, according to patient’s recollection.
    3. Patients with hearing loss not greater than 90dB at 0.125, 0.25, 0.5, 1, 2, 4, 6, and 8 kHz.
    4. Enrollment has to be accomplished within 7 days after SSHL onset.
    5. Male or female aged ≥18 to ≤70 years.
    6. Women of childbearing potential who are sexually active with opposite partners have to perform adequate contraception with a combination of a highly effective method of birth control and additional barrier contraception. [Highly effective method of birth control is defined as those, alone or in combination, that result in a low failure rate (i.e. less than 1% per year) when used consistently and correctly for the entire study duration: combined (oestrogen and gestagen) oral contraceptives, hormone implants, hormone injectables, or hormone containing intrauterine device that needed to be in place for a period of at least 2 months prior to screening. Additional barrier contraception (at least the following methods are allowed: condom of the male, diaphragm with spermicide, portio cap with spermicide) has to be used for the duration of the trial, defined as from the time of screening to at least 10 days after Day 6 (Visit 4) of the double-blind treatment phase. A single barrier method is not acceptable. Women of non-childbearing potential can be included if surgically sterile (documented complete hysterectomy or bi-tubal ligations) or post-menopausal >1 year.]
    7. Men of reproductive potential must use condoms. In addition, the female partner should also be on a safe hormonal contraception (e.g. combined oral contraceptives, hormone implants, hormone injectables or hormone containing intrauterine device) or use a barrier contraception (e.g. intrauterine device, diaphragm or portio cap with spermicide), if she is of childbearing potential.
    8. Ability to understand and to follow the study protocol.
    E.4Principal exclusion criteria
    The presence of any of the following will exclude a patient from study enrolment:
    1. Pregnant or breast-feeding female.
    2. positive pregnancy test before receiving study drug
    3. Body weight >140 kg.
    4. Bilateral SSHL.
    5. Incomplete recovery after previous SSHL.
    6. Due to history of physical efforts suspected perilymph fistula or membrane rupture.
    7. Previously existing, known retrocochlear hearing loss.
    8. Any history of any ear operation or local inflammatory disease in the past one year
    9. History of blunt or penetrating ear trauma, head trauma, barotrauma, or acoustic trauma immediately preceding SSHL.
    10. History of Menière’s disease, autoimmune hearing loss, radiation-induced hearing loss, endolymphatic hydrops.
    11. Treatment with steroids for any reason within the preceding 30 days.
    12. History of chronic inflammatory diseases or autoimmune diseases e.g. rheumatic disease, including rheumatoid arthritis, scleroderma, lupus erythematosus, polymyalgia rheumatica, polyarteritis nodosa, temporal/giant cell arteritis, Sjögren’s syndrome, or ulcerative colitis and Crohn’s disease.
    13. History of unstable angina, coronary artery stenting or bypass grafting within three months of enrolment, transient ischemic attacks or stroke within four weeks of enrolment.
    14. Prior chemotherapy or treatment with immunosuppressant drugs (azathioprine, chlorambucil, cyclophosphamide, or other alkylating agents), cyclosporine, etanercept, infliximab, interferon or any therapy with drugs known as ototoxic (e.g. aminoglycosides, cisplatin, loop diuretics, quinine etc.) in the past 6 months.
    15. Gastrointestinal pathology: lesions liable to bleed such as active peptic ulcer disease, inflammatory bowel disease, history of gastrointestinal bleeding, or recent hemorrhage at any anatomical site requiring medical intervention.
    16. Screening plasma fibrinogen level of <180 mg/dL.
    17. Known disorder of platelet function or coagulation abnormality.
    18. Platelet count of <100,000/mm3.

    22. Renal insufficiency (e.g., blood urea nitrogen or creatinine ≥2 × ULN) or patients on renal dialysis.
    23. Use of another investigational drug within 30 days prior to SSHL onset.
    24. Any other serious medical condition that might interfere with subject evaluation over the 90-day study period, based on the investigator’s judgment, e.g. planned surgical intervention or any other condition which might give doubt for non-completing the study e.g. planned holiday, distance between investigational center and place of origin.
    25. Known hypersensitivity to the drug substance or excipients.
    26. Blood or blood product infusion within one week prior to study drug.
