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   43846   clinical trials with a EudraCT protocol, of which   7282   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.

    Of a single-day IDR of 6 mg, 12 mg and 18 mg of GH001 in patients with bipolar II disorder and a current major episode of depression.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    4. Has a body mass index (BMI) in the range of 18.5 and 40 kg/m2 (inclusive) at screening.
    5. Meets the trial criteria for bipolar II disorder and is experiencing a major depressive episode, as assessed by a trial psychiatrist or registered clinical psychologist:
    -Meets the DSM-5 diagnostic criteria for bipolar II disorder with a current major depressive episode confirmed by the Mini-International Neuropsychiatric Interview (MINI) v7.0.2 -Has a Montgomery-Asberg Depression Rating Scale (MADRS) total score of ≥ 24 at screening and prior to first dose on Day 0
    8. Female patients must be either surgically sterile (hysterectomy, tubal ligation, or bilateral oophorectomy) or postmenopausal with amenorrhea for the last 2 years or remain completely abstinent (complete avoidance of heterosexual intercourse) or use a highly effective (failure rate <1%) medically accepted contraceptive method, including, but not limited to, hormone contraceptives that inhibit ovulation, intrauterine device (including hormone-releasing intrauterine device/systems) for 30 days before and 90 days after GH001 dosing and must have a negative serum pregnancy test at screening and a negative urine pregnancy test on the pre-test day (Day -1).
    10. Is able to inhale 3 liters of air from the test balloon within a single breath at screening, on the pre-test day (Day -1) and prior to first dose (Day 0). An incentive spirometer will be given to patients following screening. They will be encouraged to practice deep inhalations prior to the first dose on the test day (Day 0). Patients failing the test inhalation at screening may have the test inhalations repeated within 14 days of the original screening date.
    E.4Principal exclusion criteria
    2. Has, based on history, psychiatric assessment, and evaluation of the MINI, a current or prior diagnosis of bipolar I disorder, a manic episode, a psychotic disorder, major depressive disorder (MDD) or other mood disorder with psychotic features, obsessive compulsive disorder, post-traumatic stress disorder (PTSD), autism spectrum disorder, borderline personality disorder, schizophrenia, delusional disorder, paranoid personality disorder, schizoaffective disorder, clinically significant intellectual disability, or any other psychiatric comorbidity that renders the patient unsuitable for the trial according to the investigator’s judgment.
    3. Has one or more first degree relatives with a current or previously diagnosed psychotic disorder, bipolar I disorder, or MDD with psychotic features.
    4. Has significant suicide risk as defined by:
    (a) suicidal ideation as endorsed on items 4 or 5 on the C-SSRS within the past year, during the screening period, or at Baseline; or
    (b) suicidal behaviors within the past year; or
    (c) clinical assessment of significant suicidal risk during clinical interview; or
    (d) non-suicidal self-injury within the past year.
    6. Has taken anti-depressive medication e.g., a selective serotonin reuptake inhibitor (SSRI) such as paroxetine, fluoxetine (including in combination with olanzapine) or citalopram, a serotonin and norepinephrine reuptake inhibitor (SNRI) such as venlafaxine or duloxetine, a tricyclic antidepressant (TCA) such as amitriptyline or imipramine, an antipsychotic such as quetiapine, an atypical antidepressant such as bupropion or vortioxetine, or an N-methyl-D-aspartate (NMDA) receptor antagonist such as esketamine, within 7 days or 5 half-lives (whichever is longer) prior to dosing (exception: within the last 5 weeks in the case of fluoxetine).
    Patients who at screening are on such medication and are willing to discontinue and observe a wash-out period of 7 days or 5 half-lives (whichever is longer) prior to GH001 dosing (5 weeks for fluoxetine), can still be included, but the wash-out must be implemented, completed and documented before study drug administration. Gradual dose reduction before discontinuation and wash-out should be performed as per the investigator’s judgement and applicable medical guidelines.
    To ascertain patient safety during the potential taper and washout of anti-depressive medication, patients undergoing such taper and washout will be contacted weekly by the site.
    8. Is taking mood stabilizer therapy other than lamotrigine at screening or is, by the investigator, considered to be in the need of mood stabilizer treatment other than lamotrigine during the study.
    A period of at least 6 months without receipt of Lithium or Valproate and without an occurrence of a hypomanic episode is required prior to dosing.
    A period of at least 2 weeks or 5 half-lives (whichever is longer) without receipt of atypical anti-psychotics (e.g., aripiprazole, olanzapine, risperidone) and without an occurrence of a hypomanic episode is required prior to dosing.
    18. Has any current or past clinically significant condition (e.g., severe infection, severe pulmonary disease, uncontrolled hypertension, uncontrolled diabetes, severe cardiovascular disease, severe hepatic or renal failure, severe brain disorder (including seizure disorder, stroke, dementia, degenerative neurologic diseases, meningitis, encephalitis, and head injury with loss of consciousness) that may interfere with the interpretation of the trial results, constitutes a health risk for the patient, or that otherwise renders the patient unsuitable for the trial according to the investigator’s judgment.
    24. Patients with DSM-5 alcohol or substance use disorder (excluding tobacco and caffeine use disorders) within 6 months prior to screening.
    25. If a smoker, is unwilling or unable to abstain from cigarette smoking or vaping on the day of study drug administration (nicotine replacement therapy is permitted).
    28. A positive Coronavirus Disease 2019 (COVID-19) test during the screening, on the pre-test day (Day -1), or on Day 0 as confirmed by an antigen or polymerase chain reaction test. Subjects with a positive test result for COVID-19 during the screening period or on the scheduled trial dosing day may be rescreened, or attend their rescheduled Day -1/Day 0 visit a minimum of 5 days after initially testing positive, with/without a negative COVID-19 test result, provided that they are clinically recovered, and at the discretion of the investigator.
