Study summary

This is an open-label extension for a multicenter, randomized, double-blind, sham-controlled, adaptive design pivotal study.

Participants who complete the Hope Study (CA-0011) will be eligible to consent for screening to enroll in the OLE Hope Study (CA-0015). All participants will be treated with an Active Sensory Stimulation System (GS120) for 60 minutes daily for up to 12 months. There will be no Sham treatment group or randomization involved in this study.

Read the detailed description

This is an open-label extension for a multicenter, randomized, double-blind, sham-controlled, adaptive design pivotal study. Participants who complete the Hope Study (CA-0011) will be eligible to consent for screening to enroll in the OLE Hope Study (CA-0015). All participants will be treated with an Active Sensory Stimulation System (GS120) for 60 minutes daily for up to 12 months. There will be no Sham treatment group or randomization involved in this study.

Up to approximately 402 participants will complete the Hope Study and be offered participation in the OLE Hope Study at up to approximately 70 clinical sites.

The objective of the study will be to assess efficacy of gamma sensory stimulation (visual and audio) in slowing disease progression in the Active-Active group versus Active-Sham group for subjects with mild to moderate AD as measured functionally by the Alzheimer's Disease Cooperative Study - Activities of Daily Living (ADCS-ADL) assessment and a combined statistical test (CST) for ADCS-ADL and the Mini-Mental State Exam (MMSE).

Participants will be treated with the Sensory Stimulation System (GS120) for 60 minutes daily for up to 12 months with Active device settings. Each participant will be involved in the study for up to 13 months: approximately 12 months of treatment and 1 month of safety follow-up.The visits in the study include: a Screening/Enrollment visit (Day 0), followed by telephone training on device receipt, a clinic visit at 12 months and a telephone visit at 6 and 13 months.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Randomized and completed 12-months of participation in the Hope Study (CA-0011)
  • Non- or using adequate
  • Available/consenting Study Partner

Exclusion criteria

Exclusion Criteria:

  • Insufficient adherence to treatment in the Hope Study (CA-0011)
  • Living in continuous care nursing home (assisted living permitted)
  • Initiating or ongoing treatment with any of the following during study participation:

    • Immunomodulators or passive immunotherapies for AD (ie, monoclonal antibodies)
    • Memantine (Namenda or Namzaric)
    • Nootropic drugs except stable acetylcholinesterase inhibitors

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

What researchers measure

Primary outcomes

  1. Change from Baseline in Alzheimer's Disease Cooperative Study - Activities of Daily Living (ADCS-ADL) at 12-Months

    Function as measured by the ADCS-ADL (total score possible from 0-78, where a lower score is more affected by Alzheimer's disease)

    Time frame: Assessed for endpoint at Screening/Baseline and 12-Month clinic visits

  2. Change from Baseline in a Combined Statistical Test (CST) that creates a composite measure (combining Alzheimer's Disease Cooperative Study - Activities of Daily Living (ADCS-ADL) and Mini-Mental State Exam (MMSE) scales into one measure) at 12-Months

    Function and Cognition as measured by CST of ADCS-ADL and MMSE (ADCS-ADL total score possible from 0-78, where a lower score is more affected by Alzheimer's disease) (MMSE total score possible from 0-30, where a lower score is more affected by Alzheimer's disease)

    Time frame: Assessed for endpoint at Screening/Baseline and 12-Month clinic visits

Secondary outcomes

  1. Key Secondary: Change from Baseline in Mini-Mental State Exam (MMSE) at 12 Months

    Cognition as measured by MMSE (total score possible from 0-30, where a lower score is more affected by Alzheimer's disease)

    Time frame: Assessed for endpoint at Screening/Baseline and 12-Month clinic visits

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Feb 2024 (actual). Primary completion is estimated for Dec 2026, 34 months after the start.

Of 77 industry-sponsored interventional studies with no phase under Alzheimer Disease, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 11 and three quarters within 40. This study's planned 34 months is above that.

Counting every sponsor, half of 962 studies reached it within 29 months; a quarter within 15 and three quarters within 51.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 7, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
