Clinical Trial Summary

To investigate safety, tolerability, the effects on cognition and brain metabolism of pepinemab in early AD dementia (early AD) subjects.


Clinical Trial Description

To investigate safety, tolerability, the effects on cognition and brain metabolism of pepinemab, administered as IV infusions every 4 weeks for 44 weeks (12 infusions) in mild dementia due to Alzheimer's Disease (AD)) participants. Participants will be randomized 1:1 to receive 40 mg/kg pepinemab or placebo. This is a randomized double-blind, placebo-controlled study of pepinemab in mild dementia due to AD. The study is 52 weeks in duration, including a safety and efficacy evaluation 4 weeks after the last dose of study drug. Participants with resolved adverse events at Week 48 will have a safety telephone call at Week 52. Participants with unresolved adverse events at Week 48 will have a safety in-office visit at Week 52. The study protocol will include two sentinel participants in each of the two blinded dose arms. Sentinel dosing will be implemented by randomly assigning one study participant to one of the two dose arms in a blinded manner, treating those participants with study drug. If no unexpected serious adverse events are observed within 48 hours after the first and second participants receive treatment, two additional participants will be enrolled, with one participant assigned randomly to each of the two dose arms. Again a 48-hour safety period will be observed following treatment of the fourth participant to document any unexpected safety events that may occur. Should no unexpected serious adverse events occur within 48 hours after the third and fourth participants receive treatment, the remaining participants will be assigned to the study dose arms according to the blinded randomization scheme and the 1:1 randomization ratio. Participants will be randomized to one of two treatment arms and will receive one dose of study drug every 4 weeks during the 44-week dosing period for a total of 12 doses of study drug. The primary objective is the safety and tolerability of study drug. A key secondary objective is the change in brain metabolism as assessed by [18F]fluorodeoxyglucose (FDG)-PET in the resting state. ;
