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 subjects.
Each subject 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.
|Condition or disease||Intervention/treatment||Phase|
|Parkinson's Disease||Drug: MEDI1341 Drug: Placebo||Phase 1|
This is a randomized, double-blind, placebo-controlled study of single ascending intravenous doses of MEDI1341 in male and nonfertile female healthy volunteers, aged 18 to 65 years.
The study will include up to 6 planned cohorts; each cohort will comprise 8 subjects. Within each cohort, 6 subjects will be randomized to receive MEDI1341 and 2 will be randomized to receive placebo. A Safety Review Committee will review data from each cohort before progression to the next higher dose cohort occurs.
On Day 1, each randomized subject will receive a single 60 minute intravenous infusion of MEDI1341 or placebo and will undergo scheduled safety, pharmacokinetic, pharmacodynamic, and immunogenicity assessments. Additional study assessments will occur on Days 2, 4, 8, 15, 22, 29, 43, 57, and 92.
