NCT02051608

Brief Summary

Part 1 is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study will evaluate the efficacy and safety of gantenerumab in participants with mild Alzheimer disease. Participants will be randomized to receive either gantenerumab subcutaneously every 4 weeks or placebo subcutaneously every 4 weeks. Approved Alzheimer medication is allowed if on stable dose for 3 months prior to screening. Part 2 is an open-label extension (OLE). A positron emission tomography (PET) imaging substudy will be conducted within the main study. Eligible participants who provide separate informed consent will undergo PET imaging scans using the radioligand florbetapir as a pharmacodynamic measure of changes in brain amyloid load over time.

Outcome Measures

Primary Outcomes (3)

  • Part 2: Percentage of Participants With Adverse Events (AEs) or Serious Adverse Events (SAEs)

    An AE is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. SAE is any adverse event that is fatal or which requires or prolongs inpatient hospitalization or results in persistent or significant disability/incapacity or causes congenital anomaly/birth defect or results in a significant medical event in the investigator's judgment.

    First dose up to 4 weeks after the last dose of study drug (up to 249 weeks)

  • Part 2: Percentage of Participants With Treatment Emergent Anti-Drug Antibodies (ADAs)

    Participants were considered positive or negative for ADA based on their baseline and post-baseline sample results. The number and percentage of participants with confirmed positive ADA levels were determined for participants previously (in part 1) on Gantenerumab and Placebo. The prevalence of ADA at baseline was calculated as the percentage of participants with confirmed positive ADA levels at baseline relative to the total number of participants with a sample available at baseline. The incidence of treatment-emergent ADAs was determined as the percentage of participants with confirmed post-baseline positive ADAs relative to the total number of participants that had at least one post-baseline sample available for ADA analysis.

    First dose up to last dose (Baseline up to until maximum 5 years)

  • Part 2: Percentage of Participants With Adverse Events Leading to Discontinuation of Treatment

    Percentage of participants with adverse events leading to discontinuation from treatment were reported.

    First dose up to 4 weeks after the last dose in OLE (Up to approximately 249 weeks)

Secondary Outcomes (10)

  • Part 1: Percentage of Participants With AEs, SAEs

    First dose up to last dose (Up to approximately 152 weeks)

  • Part 1: Percentage of Participants With Treatment Emergent ADAs

    First dose up to last dose (Up to approximately 152 weeks)

  • Part 1: Gantenerumab Plasma Concentration at Multiple Timepoints

    Pre-dose: Weeks 4, 8, 12, 24, 48, 72 and Post dose: Day 4

  • Part 1: Percentage of Participants With Adverse Events Leading to Discontinuation of Treatment

    First dose up to last dose (Up to approximately 152 weeks)

  • Part 2: Percent Change From Baseline in Hippocampal Volume at Week 104

    Baseline (Part 1 screening), Week 104

  • +5 more secondary outcomes

Other Outcomes (22)

  • Part 1: Mean Change From Baseline in Alzheimer's Disease Activity Scale-Cognitive Subscale 13 (ADAS-Cog13) Scores at Week 104

    Baseline, Week 104

  • Part 1: Mean Change From Baseline in Alzheimer's Disease Cooperative Study-Activities of Daily Living (ADCS-ADL) Scores at Week 104

    Baseline, Week 104

  • Part 1: Percentage Change From Baseline in Total Tau (T-tau) in CSF at Week 104

Limitations and Caveats

As the participants transitioned early to OLE, most participants did not reach the primary analysis timepoint (Week 104). Hence, the efficacy endpoints for Part 1 became exploratory in nature.
