Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 32 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 2, Multicenter, Open-Label Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of AL001 in Heterozygous Carriers of Granulin or C9ORF72 Mutations Causative of Frontotemporal Dementia
Actual Study Start Date : September 27, 2019
Estimated Primary Completion Date : March 30, 2021
Estimated Study Completion Date : March 30, 2021

Arm Intervention/treatment
Experimental: AL001
AL001 every 4 weeks for up to 48-weeks
Drug: AL001
administered via intravenous (IV) infusion once a month

Primary Outcome Measures :
  1. Evaluation of safety and tolerability of AL001: Incidence of adverse events [ Time Frame: 48 weeks ]
    Incidence of adverse events

Secondary Outcome Measures :
  1. Pharmacokinetics (PK) of AL001 [ Time Frame: 48 weeks ]
    Concentration of AL001 at specified time points

  2. Maximum plasma concentration (Cmax) for AL001 [ Time Frame: 48 weeks ]
    Evaluate Cmax for concentration of AL001 at specified time points

  3. Area under the curve concentration (AUC) for AL001 [ Time Frame: 48 weeks ]
    Evaluate AUC for concentration of AL001 at specified time points
