Lähi-infrapunavalon terapialaite lievälle-kohtuulliselle Alzheimerin taudille (NirsCure-03A)
Monikeskuksinen, satunnaistettu, kaksoissokkokontrolloitu, lumekontrolloitu tutkimus lähi-infrapunavalon terapialaitteen tehosta ja turvallisuudesta lievästä keskivaikeaan Alzheimerin tautia sairastavilla osallistujilla (NirsCure-03A)
This study is a multicenter, randomized, double-blind, sham-device-controlled clinical trial.
A total of 320 patients with mild to moderate Alzheimer's disease (AD) are planned to be enrolled. Central stratified block randomization will be applied, with stratification based on disease severity (mild vs. moderate) and Aβ-PET subgroup center status (yes vs. no). Participants will be randomly assigned to either the treatment group or control group in a 1:1 ratio. After enrollment, participants will complete the treatment at home during a 52-week double-blind period. The treatment group will receive therapy using a near-infrared light therapy device, while the control group will use sham device. Both investigators and participants will remain blinded to treatment allocation throughout the double-blind period. Participants who complete the 52-week double-blind treatment period may choose to enter an open-label extension and receive an additional 26 weeks of active near-infrared light therapy.
