An Open-label, Adaptive Design, Positron Emission Tomography Study in Healthy Male Participants to Characterize Receptor Occupancy by MIJ821 in the Brain

Korábbi kezelés

• Any significant illness, including infectious diseases, which has not resolved within 2 weeks prior to baseline.
• Exposure to ionizing radiation as part of a research study, which, in addition to the exposure from this study, would lead to a total effective dose of more than 10 mSv in a period of one year.
• Sexually active males unwilling to use a condom during intercourse while taking study treatment and for 90 days following dosing. A condom is required for all sexually active male participants for 90 days following dosing (including vasectomized men) to prevent them from fathering a child AND to prevent delivery of the investigational drug via seminal fluid to their partner.

Más betegség

• Hypersensitivity to NMDA antagonists (MIJ821 or other compounds with similar mechanism of action, like ketamine or compounds with similar chemical structure to ketamine) or to any excipients, local anesthetics, or anticoagulants used in this study.
• Resting heart rate in sinus rhythm outside 50-90 bpm
• Any history of neurological disorders, including, but not limited to any of the followings:
• Any history of stroke or known cerebrovascular disorders (e.g. aneurysm or arteriovenous malformation) or known aneurysmal vascular disease in other location (e.g. aorta)
• Any history or presence of epilepsy or of seizures or convulsions of any kind.
• Any history of head trauma leading to permanent sequelae or history of head trauma leading to clinically significant but transient symptoms within 2 years of baseline.

Egyéb

• Any of the following ECG abnormalities at Screening or Baseline:
• PR interval outside 110-200 ms
• QRS duration outside 70-120 ms
• QTcF > 450 ms
• Score "yes" on item 4 or item 5 of the Suicidal Ideation section of the C-SSRS, if this ideation occurred in the past 6 months from screening, or "yes" on any item of the Suicidal Behavior section, except for the "Non-Suicidal Self-Injurious Behavior" (item also included in the Suicidal Behavior section), if this behavior occurred in the past 2 years.

• Signed informed consent must be obtained prior to participation in the study
• Healthy males, aged 23 to 55 years (inclusive), and in good health as determined by past medical history, physical and neurological examination, vital signs, electrocardiogram, and laboratory tests at Screening and Baseline (whenever applicable)
• At screening and at baseline (Day -1), vital signs after 3 minutes resting (in sitting position during screening and supine position during baseline) must be within the following ranges:
• Body temperature (otic) from 35.0 °C to 37.5 °C, inclusive
• Systolic blood pressure (BP) from 90 to 139 mmHg, inclusive
• Diastolic BP from 50 to 89 mmHg, inclusive.
• Pulse rate from 50 to 90 beats per minute, inclusive
• Participants must weigh at least 50 kg to participate in the study and must have a body mass index (BMI) within the range of 18.0 to 29.9 kg/m² at screening. BMI = body weight (kg) / height2 (m2)
• Participants must be able to communicate well with the Investigator and to comply with the requirements of the entire study, including adhering to study restrictions and visit schedule
