What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 92 participants in total. It began in 2024-10-22 with a primary completion date of 2026-04.

Brief Summary

BnH-015B is a small molecule compound that targets the GluN2B binding site on NMDA receptors and positively modulates. BnH-015B has shown, through nonclinical trials, to improve symptoms of cognitive decline by regulating the BDNF/TRKβ and microglia-mediated IL-33/OPN signaling pathways; therefore, it is expected to be a promising new drug that can significantly improve symptoms associated with Alzheimer's disease, including memory loss.

confirmed as amyloid positive via amyloid PET * \[Part II\] Patients diagnosed within the last 5 years prior to screening * \[Part II\] The subject (or the subject's legal representative) and caregiver must sign the consent for participation in the study, and the same caregiver must assist the subject throughout the entire study period and be continuously available for contact * \[Part II\] Individuals who possess sufficient vision, hearing, language ability, motor function, and comprehension to follow the test procedures in the investigator's judgment * \[Part I\&II\] Individuals

this clinical trial, completely understand it, and voluntarily decide to participate and agree in writing to follow the instructions (however, for Part II, consent from a guardian can be substituted for this) * \[Part I\&II\] Individuals deemed suitable as subjects for this study by the investigator based on physical examinations, clinical laboratory tests, and medical history evaluations Exclusion Criteria: * \[Part II\] Patients with a history of unstable angina, myocardial infarction, progressive chronic heart failure (New York Heart Association class III or IV), or clinically significant electrocardiographic abnormalities within the year prior to screening * \[Part II\] Patients with a history of vascular dementia * \[Part II\] Patients diagnosed with dementia or cognitive impairment not related to Alzheimer's disease, including but not limited to significant head trauma, alcohol abuse, frontotemporal dementia, Huntington's disease, Parkinsonian syndromes (e.g., Parkinson's disease, Lewy body dementia), significant cerebrovascular disease, and/or significant seizure disorders * \[Part II\] Patients with psychotic symptoms primarily due to conditions other than Alzheimer's disease causing dementia (e.g., schizophrenia, schizoaffective disorder, delusional disorder, or mood disorders with psychotic symptoms) * \[Part II\] Patients who must take contraindicated medications throughout the entire study period * \[Part II\] Patients who have used cognitive-impairing, long-term permissible concomitant medications (e.g., antidepressants, anticonvulsants, atypical and typical antipsychotics, benzodiazepines) in unstable doses for at least 8 weeks prior to screening visit and during the screening period * \[Part II\] Patients who have

gastroesophageal reflux disease) or a history of surgery (except for simple appendectomies or hernia surgeries) that may affect the safety/tolerability and pharmacokinetic evaluations of the investigational product * \[Part I\&II\] Individuals who have hypersensitivity reactions or have a clinically significant history of hypersensitivity reactions to drugs that contain the ingredient of

one or more of the following results in clinical laboratory tests during screening including additional tests: Blood levels of AST (SGOT), ALT (SGPT) \> 1.5 times the upper limit of the normal range, eGFR calculated using the CKD-EPI equation: \< 60 mL/min/1.73m2 * \[Part I\&II\] Individuals who have taken any prescription drugs or herbal medicine within 2 weeks prior to the planned administration date of the investigational product, or any over-the-counter (OTC) drugs, dietary supplements including liver function aids, or vitamin preparations within 1 week (however, the investigator may choose

enzyme-inhibiting drugs like clarithromycin within 1 month prior to the planned administration date of the investigational product * \[Part I\&II\] Individuals who have participated in another clinical trial (including bioequivalence studies) and received an investigational product within 6 months prior to the planned administration date of the investigational product * \[Part I\&II\]
