简要总结
This is a randomized, double-blind, placebo-controlled study of single and multiple ascending dosage levels of AZD6423 in healthy volunteers. The study includes an up to 28-day screening period, an in-house period during which AZD6423 or placebo will be administered IV, and a 4- to 10-day follow-up period after discharge.
详细描述
In Part 1 of the study (single ascending dose portion), approximately 40 subjects will be randomly assigned. Eight (8) subjects will be randomized in each of 5 dosage-level cohorts (AZD6423 or placebo). Within each cohort, 6 subjects will be randomized to receive AZD6423 and 2 subjects will be randomized to receive placebo. Each subject will receive only one dose of either AZD6423 or placebo on Day 1. In Part 2 of the study (multiple ascending dose portion), approximately 24 subjects will be randomly assigned. Eight (8) subjects will be randomized in each of 3 dosage-level cohorts. Within each cohort, 6 subjects will be randomized to receive AZD6423 and 2 subjects will be randomized to receive placebo. Each subject will receive three doses of either AZD6423 or placebo.

入选标准
- •Subjects must understand the nature of the study and must provide signed and dated written informed consent in accordance with local regulations before the conduct of any study-specific procedures.
- •All male subjects who are biologically capable of having children must agree and commit to the use of a reliable method of birth control for the duration of the study and for 15 days after dose administration.

- •Subjects must be fluent in English.
排除标准
- •A history or presence of a clinically significant hepatic, renal, gastrointestinal, cardiovascular, endocrine, respiratory, immunologic, hematologic, dermatologic, or neurologic abnormality.
- •A clinically significant abnormality on physical examination, neurological examination, EEG, ECG, vital signs or laboratory evaluations at screen or between screen and dose administration.
- •A history of seizure.
- •A history of head trauma, including closed head injury with loss of consciousness.
- •Any history of suicide attempt or suicidal behavior, or, in the opinion of the investigator, clinically significant risk of suicide or violent behavior.
- •Urine drug screen positive for a drug of abuse
- •A family history of schizophrenia, schizoaffective disorder, or psychosis in first degree relatives.
