A Pivotal Study of LIPUS-Brain in Patients with Early Alzheimer's Disease

JRCT ID: jRCT2032230125

Registered date:08/06/2023

Basic Information

• Recruitment status: Recruiting
• Health condition(s) or Problem(s) studied: Early Alzheimer's Disease
• Date of first enrollment: 31/10/2023
• Target sample size: 220
• Study type: Interventional
• Intervention(s): Perform 3 sets every other day, 3 times a day for 20 minutes each time (at intervals of 5 minutes or more between each session). Considering this as one course, one course (weeks 0, 12, 24, 36, 48, and 60) will be administered during the 12-week period.

Outcome(s)

• Primary Outcome: Changes in ADAS-J-cog-14 scores from baseline to 72 weeks

Secondary Outcome

'- Changes in ADAS-J-cog-14 scores from baseline to 24 and 48 weeks.
- Changes in CDR-SB from baseline to 48 and 72 weeks.
- Changes in MMSE-J, FAQ, NPIQ-J, J-ZBI, WMS-R, EQ-5D-5L and ABC from baseline to 24, 48 and 72 weeks.
- Prevalence of responders at 24, 48, and 72 weeks defined as those with no deterioration or even improvement in ADAS-J-cog-14 scores.
- Transition rate from MCI due to AD to AD at 72 weeks.
- The safety endpoints include adverse symptoms until 72 weeks and any abnormal MRI findings at 72 weeks.
- Termination due to aggravation of dementia symptoms.
