Clinical Trial Summary

The ACHIEVE Brain Health Follow-Up Study is a 3-year follow-up to the Aging and Cognitive Health Evaluation in Elders (ACHIEVE) randomized study to determine the long-term effect of hearing intervention vs. successful aging/delayed hearing intervention on rates of cognitive decline and incident mild cognitive impairment or dementia.


Description:

ORIGINAL ACHIEVE TRIAL: The Aging and Cognitive Health Evaluation in Elders (ACHIEVE) study is an National Institute on Aging (NIA)-sponsored Phase III randomized controlled trial (R01AG055426; Multiple Principal Investigators: Lin/Coresh) investigating whether hearing loss treatment versus an aging education control intervention reduces cognitive decline over a 3-year follow-up period. From 2018 to 2019, the investigators recruited 977 adults aged 70-84 years with untreated mild-to-moderate hearing loss who were randomized 1:1 at baseline to receive hearing intervention (HI; best practices hearing services and technologies) versus a successful aging (SA) education control intervention (i.e., one-on-one sessions with a health educator covering topics important for healthy aging). Participants are followed semi-annually at the ACHIEVE field sites (Washington County, Maryland; Jackson, Mississippi; Minneapolis, Minnesota; Forsyth County; North Carolina) with final Year 3 study visits for ACHIEVE participants scheduled from 2021-2022. After the participants Year 3 visit, all participants randomized to the SA education control group will also be offered the hearing intervention. Final Year 3 results from this original trial will indicate whether hearing intervention (versus a successful aging control intervention) reduces cognitive decline over a 3-year interval after randomization. ACHIEVE BRAIN HEALTH FOLLOW-up STUDY: The current study will continue following the ACHIEVE cohort for an additional 3 years after the participants Year 3 visit (i.e., total of 6 years) to determine the long-term effects of hearing intervention (i.e., participants randomized to HI at ACHIEVE baseline) versus successful aging/delayed HI control (i.e., participants randomized to SA at ACHIEVE baseline and offered HI after the participants ACHIEVE Year 3 visit) on cognitive, dementia, and brain outcomes. Given that cognitive impairment typically reflects the slow accumulation of pathologic changes, the benefits of hearing intervention in slowing this decline may not be fully appreciable within just 3 years. Therefore, this 6-year follow-up of the cohort will allow the investigators to fully evaluate the longer, cumulative impact of hearing loss treatment on older adults. Such findings will complement the main trial results in 2023 and directly inform clinical and policy decisions around the potential use of hearing interventions to reduce the risk of cognitive decline and Alzheimer's disease and related dementias (ADRD).

Study Design


Intervention

Other:
Hearing intervention
The hearing intervention is best practices hearing rehabilitation treatment program, consisting of fitting with hearing aids and other hearing assistive technologies along with comprehensive, individualized hearing rehabilitation sessions with a study audiologist spaced over the 2-3 months post-fitting designed to provide all the active components of the intervention. Participants also received semi-annual booster sessions with the study audiologist for 3 years and will continue to receive hearing healthcare from the study audiologist and complete semi-annual sessions for 3 additional years.
Successful aging/delayed hearing intervention
The successful aging health education program follows the protocol and materials developed for the 10 Keys to Healthy Aging program. The program involved individualized sessions with a study health educator, with initial sessions spaced over the 2-3 months post-randomization and semi-annual sessions for 3 years. Upon completion of the ACHIEVE trial, these participants are offered the best practices hearing rehabilitative treatment program with comprehensive, individualized sessions post-fitting and will receive semi-annual booster sessions with the study audiologist for 3 years.

Outcome

Type Measure Description Time frame Safety issue
Primary Change in global cognition Change from original ACHIEVE trial baseline to ACHIEVE-BHFU final visit in global cognition, as assessed using a factor score derived from completion of a neurocognitive testing battery. The ACHIEVE and ACHIEVE Brain Health studies administer a neurocognitive testing battery annually, which includes the following cognitive tests: Delayed Word Recall, Incidental Learning, Logical Memory I and II, Word Fluency, Animal Naming, Boston Naming, Trail Making Test A and B, Digit Span Backwards, and Digit Symbol Substitution. Factor analytic methods use all items from all tests in the battery to generate a single global cognition score. ACHIEVE Baseline, ACHIEVE-BHFU Year 3 (~6 years)
Primary Mild cognitive impairment (MCI) / dementia Time until composite outcome of adjudicated diagnosis of mild cognitive impairment (MCI) or dementia over the course of follow-up from original ACHIEVE trial baseline until ACHIEVE-BHFU final visit. 6 years
Secondary Change in cognition memory domain Change from original ACHIEVE trial baseline to ACHIEVE-BHFU final visit in the cognition memory domain, as assessed using a memory domain factor score derived from completion of a neurocognitive testing battery. The cognitive tests for the memory domain include Delayed Word Recall, Incidental Learning, and Logical Memory I and II. These tests have an underlying commonality, or factor, that is unable to be directly measured, and factor analytic methods use items from the tests noted to generate a single overall memory score. ACHIEVE Baseline, ACHIEVE-BHFU Year 3 (~6 years)
Secondary Change in cognition executive function domain Change from original ACHIEVE trial baseline to ACHIEVE-BHFU final visit in the cognition executive function domain, as assessed using an executive function domain factor score derived from completion of a neurocognitive testing battery. The cognitive tests for the executive function domain include Trail Making Test A and B and Digit Symbol Substitution. These tests have an underlying commonality, or factor, that is unable to be directly measured, and factor analytic methods use items from the tests noted to generate a single overall executive function score. ACHIEVE Baseline, ACHIEVE-BHFU Year 3 (~6 years)
Secondary Change in cognition language domain Change from original ACHIEVE trial baseline to ACHIEVE-BHFU final visit in the cognition language domain, as assessed using a language domain factor score derived from completion of a neurocognitive testing battery. The cognitive tests for the language domain include Word Fluency, Animal Naming, and Boston Naming. These tests have an underlying commonality, or factor, that is unable to be directly measured, and factor analytic use items from the tests noted to generate a single overall language score. ACHIEVE Baseline, ACHIEVE-BHFU Year 3 (~6 years)
Secondary Change in regional brain volumes Change in volume (cm^3) of each MRI-defined brain region of interest from ACHIEVE trial baseline to ACHIEVE-BHFU final visit if the participant previously participated in the ACHIEVE-MRI ancillary study, or from ACHIEVE-BHFU baseline visit to ACHIEVE-BHFU final visit if the participant was not previously enrolled in the ACHIEVE-MRI ancillary study. If in ACHIEVE-MRI: ACHIEVE Baseline, ACHIEVE-BHFU Year 3 (~6 years); if not in ACHIEVE-MRI: ACHIEVE-BHFU Baseline, ACHIEVE-BHFU Year 3 (~2.5 years)
Secondary Change in white matter tract integrity Change in MRI fractional anisotropy and mean diffusivity in white matter tracts from ACHIEVE trial baseline to ACHIEVE-BHFU final visit if the participant previously participated in the ACHIEVE-MRI ancillary study, or from ACHIEVE-BHFU baseline visit to ACHIEVE-BHFU final visit if the participant was not previously enrolled in the ACHIEVE-MRI ancillary study. If in ACHIEVE-MRI: ACHIEVE Baseline, ACHIEVE-BHFU Year 3 (~6 years); if not in ACHIEVE-MRI: ACHIEVE-BHFU Baseline, ACHIEVE-BHFU Year 3 (~2.5 years)
