Brief Summary:
A first in human phase 1 study in healthy volunteers and participants with Granulin (GRN) mutation causative of frontotemporal dementia (FTD) to assess AL001 safety, tolerability, pharmacokinetics, and pharmacodynamics

Condition or disease Intervention/treatment Phase
Healthy Frontotemporal Dementia Biological: AL001 Other: Placebo Phase 1

Detailed Description:
This is a first-in-human Phase 1 study designed to investigate the safety, tolerability, PK and PD of intravenously administered AL001 in Healthy Volunteers and FTD-GRN mutation carriers.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 64 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A First in Human Phase 1 Study in Healthy Volunteers and in Participants With Frontotemporal Dementia (FTD) With Granulin Mutation
Actual Study Start Date : September 14, 2018
Actual Primary Completion Date : December 31, 2019
Actual Study Completion Date : December 31, 2019

Arm Intervention/treatment
Experimental: AL001
Up to six single ascending doses of AL001
Biological: AL001
Active dose of AL001

Placebo Comparator: Saline Solution
Saline solution will be administered as a single infusion for each cohort in a ratio of 6 active and 2 placebo subjects
Other: Placebo
Saline solution administered as a single infusion as palcebo.

Primary Outcome Measures :
  1. Evaluation of safety and tolerability of AL001 measured by number of subjects with adverse events and Dose Limiting Adverse Event (DLAEs) [ Time Frame: 85 days ]
    Incidence of adverse events and dose limiting Adverse Events during the DLAE observation period and/or study treatment periods.

Secondary Outcome Measures :
  1. Pharmacokinetics (PK) of AL001 [ Time Frame: 85 days ]
    Serum and cerebrospinal fluid (CSF) concentration of AL001 at specified time points

  2. Maximum plasma concentration (Cmax) for AL001 [ Time Frame: 85 days ]
    Evaluate Cmax for serum and CSF concentration of AL001 at specified time points

  3. Area under the curve concentration (AUC) for AL001 [ Time Frame: 85 days ]
    Evaluate AUC for serum and CSF concentration of AL001 at specified time points
