The goal of this study is to explore the efficacy and safety of near-infrared light combined with lecanemab in patients with mild Alzheimer's disease (AD).
This study will employ a randomized, double-blind, sham-controlled method with an open-label extension phase. This trial contains the core phase and an extension phase. During the core phase, eligible subjects were selected and randomized (experimental group: control group = 1:1). The subjects who entered the experimental group received treatment with a near-infrared light therapy device combined with lecanemab for 16 weeks. The subjects who entered the control group received treatment with a near-infrared light therapy device simulator (sham stimulation) combined with lecanemab for 16 weeks. After completing the core phase, patients from both groups of the core phase are eligible to enter the extension phase. In the extension phase, all the participants were treated with a near-infrared light therapy device combined with lecanemab up to week 48.

| The change from baseline in the Alzheimer's Disease Assessment Scale-Cognitive (ADAS-cog). | The Alzheimer's Disease Assessment Scale - Cognitive Section (ADAS-Cog-14) is a comprehensive tool used to evaluate cognitive function in individuals. The unabbreviated scale title is the Alzheimer's Disease Assessment Scale - Cognitive Section. The minimum score on this scale is 0, while the maximum score is 144. Importantly, higher scores on the ADAS-Cog-14 indicate worse cognitive function. This scale assesses various cognitive domains, and an increasing score reflects more severe cognitive impairment. | 16 weeks. |

| 32 weeks, 48 weeks. |
| The change from baseline in the Mini-Mental State Examination (MMSE). | The Mini-Mental State Examination (MMSE) is a widely used tool for assessing cognitive function. The unabbreviated scale title is the Mini-Mental State Examination. The minimum score on this scale is 0, while the maximum score is 30. Higher scores on the MMSE indicate better cognitive function. This scale evaluates various cognitive domains such as orientation, attention, calculation, recall, and language. A higher score reflects better cognitive performance. | 16 weeks, 32 weeks, 48 weeks. |
| The change from baseline in the Clinical Dementia Rating - Sum of Boxes (CDR-SB). | The Clinical Dementia Rating - Sum of Boxes (CDR-SB) is a comprehensive assessment tool used to evaluate the severity of dementia. The unabbreviated scale title is the Clinical Dementia Rating - Sum of Boxes. The minimum score on this scale is 0, while the maximum score is 18. Higher scores on the CDR-SB indicate worse cognitive and functional impairment. This scale assesses various domains including memory, orientation, judgment and problem-solving, community affairs, home and hobbies, and personal care. An increasing score reflects more severe dementia. | 16 weeks, 32 weeks, 48 weeks. |
| The change from baseline in the Alzheimer's Disease Cooperative Study - Activities of Daily Living Scale (ADCS-ADL). | The Alzheimer's Disease Cooperative Study - Activities of Daily Living Scale (ADCS-ADL) is a tool designed to assess the functional abilities of individuals in their daily activities. The unabbreviated scale title is the Alzheimer's Disease Cooperative Study - Activities of Daily Living Scale. The minimum score on this scale is 0, while the maximum score is 78. Higher scores on the ADCS-ADL indicate better functional ability in daily living activities. This scale evaluates various aspects of daily living, such as personal care, household chores, and financial management. A higher score reflects better performance in activities of daily living. | 16 weeks, 32 weeks, 48 weeks. |
