Primary Outcome Measures
NameTimeMethod
Tolerability as Measured by Participant Withdrawal for an Adverse Event4 months SAD; 7 months MAD

Tolerability measured by participant withdrawal for an adverse event from randomization through end of study

Secondary Outcome Measures
NameTimeMethod
Mean Termination Half Life (t 1/2) of Medi18141 month

Mean termination half life (t 1/2) of Medi1814 during 28 day period after dose administration start (SAD Day 1 dose, MAD 3rd dose)

Maximum Plasma Concentration (Cmax) of Medi18141 month

Maximum plasma concentration (Cmax) of Medi1814 during 28 day period after dose administration start (prior to dosing, during infusion, 1, 2, 4, 8, 24, 48 hr, 7, 14,21, and 28 days)

Biomarkers: Amyloid-beta in Cerebral Spinal Fluid (Two Amyloid Bets Peptides of 40 and 42 Amino Acids Were Assessed)Day 29 in SAD; Day 85 in MAD

Biomarkers: Amyloid-beta in cerebral spinal fluid, mean percent change from baseline

Area Under the Concentration Time Curve (AUC) Time 0 to t (28 Days After 1st Dose SAD and MAD and After 3rd Dose in MAD, Day 57)1 month

Area Under the Concentration time curve (AUC) time 0 to t; calculated from Just prior to dose administration start to 28th day after dose (pre infusion, during infusion, 1,2,4,8,24,48 hr 7, 14, 21, and 28 day)

Biomarker: Total Amyloid-beta 1-42 in PlasmaDay 29 in SAD; Day 85 in MAD

Biomarker: Total Amyloid-beta 1-42 in plasma, mean percent change from baseline

Medi1814 Concentration in CSF SamplesSAD Day 29; MAD Day 85

Medi1814 concentration in CSF Samples; number of sampled subjects with a value above the lower limit of quantification

Immunogenicity: Anti-drug Antibody Titer4 months SAD (6 tests over 4 months; week 1, 2, 4, 8, 12, 16); 7 months MAD (7 monthly tests)

Immunogenicity: Anti-drug antibody titer, subject counted if titer 50 or greater on any test, else 0 if all \<50
