NCT03272165

Brief Summary

This is a study of single ascending intravenous doses of MEDI1341 or placebo in up to 48 healthy volunteers, aged 18 to 65 years. The study will include up to 6 planned cohorts; each cohort will comprise 8 participants. Each participant will receive a single 60 minute intravenous infusion of MEDI1341 or placebo and will undergo scheduled assessments over a period of 13 weeks. The main aim of the study is to assess the safety and tolerability of single doses of MEDI1341 in healthy volunteers.

Outcome Measures

Primary Outcomes (14)

  • Number of Participants With Treatment Emergent Adverse Events (TEAEs) and Treatment Emergent Serious Adverse Events (TESAEs)

    An adverse event (AE) is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. A serious adverse event (SAE) is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. The TEAEs are defined as events present at baseline that worsened in intensity after administration of study drug or events absent at baseline that emerged after administration of study drug.

    Day 1 through 92 days after a single dose of study drug

  • Number of Participants With Abnormal Vital Signs, Physical and Neurological Examinations, and Body Weight Measurements Reported as TEAEs

    Vital signs assessment included body temperature, respiration rate, pulse rate, and blood pressure. Participants with abnormal vital signs, physical and neurological examinations, and body weight measurements reported as TEAEs are reported.

    Day 1 through 92 days after a single dose of study drug

  • Change from Baseline in 12-Lead Electrocardiogram (ECG) Data in Paper and Digital Recordings (PR Interval, QRS Duration, QT Interval, QTcF Interval, and RR Interval)

    Changes from baseline in 12-Lead ECG data in paper recordings (PR interval, QRS duration, QT interval, and QTcF interval) and digital recordings (PR interval, QRS duration, QT interval, QTcF interval, and RR interval) are reported.

    12-lead paper ECG: Baseline (Day -49) to Day 92; Digital ECG: Baseline (Day 1) to Day 92

  • Change from Baseline in Heart Rate by 12-Lead ECG in Paper and Digital Recordings

    Change from baseline in heart rate by 12-Lead ECG in paper and digital recordings are reported.

    12-lead paper ECG: Baseline (Day -49) to Day 92; Digital ECG: Baseline (Day 1) to Day 92

  • Number of Participants With Abnormal Laboratory Parameters Reported as TEAEs

    Laboratory assessment included hematology, clinical chemistry, and urinalysis. Participants with abnormal laboratory parameters reported as TEAEs are reported.

    Day 1 through 92 days after a single dose of study drug

  • Number of Abnormal Findings for Ophthalmic Assessment (Ophthalmic Examination and Slit-lamp Examination) for Placebo and Cohorts 4 to 6 at Follow-up Visit

    Number of abnormal findings for ophthalmic assessment (ophthalmic examination and slit-lamp examination) at follow-up visit (Day 57) are reported.

    Follow-up Visit (Day 57)

  • Intraocular Pressure at Screening for Placebo and Cohorts 4 to 6

    Intraocular pressure at Screening (Day -49) is reported.

    Screening (Day -49)

  • Intraocular Pressure at Day 29 for Placebo and Cohorts 4 to 6

    Intraocular pressure at Day 29 is reported.

    Day 29

  • Intraocular Pressure at Day 92 for Placebo and Cohorts 4 to 6

    Intraocular pressure at Day 92 is reported.

    Day 92

  • Number of Participants With Injection Site Reactions

    Participants who had injection site reactions (bleeding, bruising, erythema, swelling, or induration) on Day 1 are reported.

    Day 1

  • Visual Analogue Scale (VAS) Pain Score for Site Reaction Pain

    The VAS (0 to 10 cm) was used to describe reaction site pain. The score 0 means 'no pain at all' and 10 score means 'worst pain imaginable'. The higher the VAS score, the greater the reaction site pain experienced.

    Day 1 (within 24 hours after end of infusion)

  • Number of Participants With Suicidal Ideation and Suicidal Behavior Assessed by Columbia Suicide Severity Rating Scale (C-SSRS)

    The C-SSRS is a scale capturing occurrence, severity, and frequency of suicide-related thoughts and behaviours, and has a binary response (yes/no). * Suicidal Ideation: a "yes" answer to any one of 5 suicidal ideation questions: wish to be dead, non-specific active suicidal thoughts, active suicidal ideation with any methods (not plan) without intent to act, active suicidal ideation with some intent to act without specific plan, active suicidal ideation with specific plan and intent. * Suicidal Behaviour: a "yes" answer to any of 5 suicidal behaviour questions: preparatory acts or behaviour, aborted attempt, interrupted attempt, actual attempt (non-fatal), completed suicide.

    Screening (Day -49) through 92 days after a single dose of study drug

  • Number of Participants With Montreal Cognitive Assessment (MoCA) Total Score at Screening (Day -1)

    The MoCA is s standardized cognitive screening tool for mild cognitive impairment and dementia. The total score was used as outcome measure and this score ranges from 0-31, with higher scores representing better cognitive ability and scores below 26 were considered as cognitive dysfunction.

    Screening (Day -1)

  • Number of Participants With MoCA Total Score at Day 92

    The MoCA is s standardized cognitive screening tool for mild cognitive impairment and dementia. The total score was used as outcome measure and this score ranges from 0-31, with higher scores representing better cognitive ability and scores below 26 were considered as cognitive dysfunction.
