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   44338   clinical trials with a EudraCT protocol, of which   7368   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.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    Subject eligibility is determined according to the following criteria prior to entry into the study:
    1. The subject signs and dates a written informed consent form.
    2. The subject is male or female and aged 18 to 65 years, inclusive, at the time of informed consent.
    3. The subject, if male, weighs more than or equal to 50 kg (110 lbs) and, if female, weighs more than or equal to 45 kg (99 lbs).
    4. The subject has a body mass index (BMI) between 18.5 and 35.0 kg/m2, inclusive.
    5. The subject has a primary diagnosis of MDD, without psychotic features, according to Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM 5) criteria, as assessed by a board-certified psychiatrist. MDD should be the principal diagnosis and the condition that best accounts for the clinical presentation. Subjects with a secondary diagnosis of generalized anxiety disorder or social anxiety disorder may be included if, in the principal investigator’s judgment, such diagnosis will not interfere with participation in the study or with outcome assessments. The diagnostic assessment must include a face-to-face evaluation of the subject using the Mini International Neuropsychiatric Interview (MINI).
    6. The subject has MDD that is resistant to treatment (ie, TRD), defined as failure to respond to at least 2, but not more than 5, adequate trials of pharmacological treatment in the current episode, as determined using the MGH ATRQ.
    7. The subject qualifies as a candidate for receiving ketamine infusions as a treatment for their depression, in the opinion of the investigator.
    8. The subject is naïve to ketamine treatment.
    9. The subject has a HAMD-17 total score of ≥22 at Screening (Visit 1).
    10. The subject is on stable pharmacological treatment for depression (≤50% change in dose) during the last 6 weeks prior to Randomization (Visit 4). Subjects who are not currently taking pharmacological treatment for depression may be eligible, with the approval of the medical monitor.
    11. The subject is euthyroid. An abnormally high or low thyroid-stimulating hormone level may be corroborated by T3 and T4 levels in addition to a comprehensive history and physical examination to rule out a thyroid disorder. Subjects maintained on thyroid medication must be euthyroid for a period of ≥6 months prior to Screening (Visit 1).
    12. A male subject who is nonsterilized and sexually active with a female partner of childbearing potential agrees to use barrier method of contraception (eg, condom with or without spermicide) from signing of informed consent throughout the duration of the study and for 100 days after the last dose of study drug. The female partner of a male subject should also be advised to use a highly effective method of contraception.
    13. A female subject of childbearing potential who is sexually active with a nonsterilized male partner agrees to use a highly effective method of contraception from signing of informed consent throughout the duration of the study and for 40 days after the last dose of study drug.
    E.4Principal exclusion criteria
    Any subject who meets any of the following criteria will not qualify for entry into the study:
    1. The subject is found to be a match in the subject registry database with a subject who has participated in another study within the last 30 days (or at any time for an excluded medical or psychiatric condition).
    2. The subject has received any investigational compound within 90 days prior to the first dose of study drug.
    3. The subject is an immediate family member, study site employee, or is in a dependent relationship with a study site employee who is involved in conduct of this study (eg, spouse, parent, child, sibling) or may consent under duress.
    4. The subject has any active or unstable medical condition or an abnormality that may affect safety, increase risk of seizure, or lower the seizure threshold, or may put them at risk due to their participation in this study, as judged by the investigator.
    5. The subject or any immediate family member has a seizure disorder or a history of seizure disorder, except febrile convulsions.
    6. The subject is currently diagnosed with a personality disorder, dementia, eating disorder, schizophrenia, schizoaffective disorder, or bipolar disorder.
    7. The subject has a history of neurological abnormalities that is judged by the medical monitor to preclude the subject’s participation in the study; or brain injury including traumatic injury, perinatal encephalopathy, and postnatal brain damage, blood-brain barrier abnormality, and cavernous angioma.
    8. The subject has a history of cerebral arteriosclerosis.
    9. The subject is currently diagnosed with glaucoma.
    10. The subject is at an imminent risk of suicide per the C-SSRS (score of 5) or per the investigator’s clinical judgment.
    11. The subject has a history of cancer, except basal cell carcinoma that has been in remission for ≥5 years prior to Screening (Visit 1).
    12. The subject has known gastrointestinal (GI) disease or GI procedure that could interfere with the oral absorption or tolerance of TAK-653, including difficulty swallowing tablets.
    13. The subject has an abnormal and clinically-significant ECG at Screening (Visit 1).
    14. The subject has abnormal Screening (Visit 1) clinical laboratory values that, in the opinion of the investigator, suggest a clinically-significant underlying disease. Subjects with liver function test (LFT) results that meet any of the discontinuation or withdrawal criteria must be excluded (see Section 7.4).
    15. The subject has uncontrolled hypertension or a systolic blood pressure of >150 mm Hg or diastolic blood pressure >95 mm Hg at Screening (Visit 1).
    16. The subject has a positive urine test result for drugs of abuse (defined as any illicit drug use) at Screening (Visit 1) or Day 1 (Visit 4).
    17. The subject has a blood alcohol content of ≥0.06% at Screening (Visit 1), prior to ketamine infusion (Day -5 or Day -1), or Day 1 (Visit 4).
    18. The subject is currently diagnosed with abuse of or dependence on alcohol or other drugs (except nicotine). The subject will be allowed to enroll if his/her drug and alcohol abuse/dependence is in full (complete, not partial) sustained (>1 year) remission.
    19. The subject has a positive test result for hepatitis B surface antigen (HBsAg) or hepatitis C virus antibody (anti-HCV), or is known to be human immunodeficiency virus (HIV) positive, at Screening (Visit 1).
    20. The subject has a known hypersensitivity to any component of the formulation of TAK-653.
    21. The subject has any contraindication to the administration of ketamine.
    22. The subject has taken any excluded medication or food product or received any excluded procedure during the time periods listed in Section 7.3.
    23. The subject has poor peripheral venous access.
    24. If female, the subject is pregnant or lactating or intending to become pregnant before participating in this study, during the study, and within 40 days after last dose of the study drug; or intending to donate ova during such time period.
    25. If male, the subject intends to donate sperm during the course of this study or within 100 days after the last dose of study drug.
