Clinical trials

This is a randomized, double-blind, placebo-controlled, dose-finding, Phase 2a study designed to evaluate the safety and efficacy of KDS2010 in overweight or obese patients. Based on preliminary efficacy observed in the Phase 1 study, this clinical trial is being conducted in Korea. After a minimum 2-week run-in period, subjects who meet the inclusion and exclusion criteria will be randomized to the treatment group or placebo group at a 2:1 ratio in each stage. Subjects will receive the investigational product for 12 weeks following randomization. The study will be conducted in three stages. Approximately 75 subjects will be enrolled, with 6 subjects in the KDS2010 120 mg group and 3 subjects in the placebo group in Stage 1, 22 subjects in the KDS2010 180 mg group and 11 subjects in the placebo group in Stage 2, and 22 subjects in the KDS2010 240 mg group and 11 subjects in the placebo group in Stage 3. The primary objectives are to assess the efficacy and safety of KDS2010 in overweight or obese patients. Exploratory objectives include evaluating the proportion of subjects achieving a weight reduction of more than 25% from baseline at Week 12 and assessing changes in MAO-B specific activity and adiponectin levels. Based on nonclinical and Phase 1 clinical data, KDS2010 will be administered orally once daily at doses of 120 mg, 180 mg, and 240 mg throughout the study.

A randomized, double-blind, placebo-controlled, dose-finding Phase 2a clinical trial will be conducted to evaluate the efficacy and safety of KDS2010 in patients with Mild Cognitive Impairment (MCI) due to Alzheimer's disease (AD) and mild dementia due to Alzheimer's disease. Based on preliminary efficacy observed in the Phase 1 clinical trial, a clinical trial will be conducted in Korea. Eligible patients diagnosed with MCI or mild Alzheimer's disease will be stratified by disease stage (MCI/mild AD) prior to randomization. Subjects will be randomly assigned in a 1:1:1 ratio to either Treatment Group 1, Treatment Group 2, or the Control Group. The investigational product will be administered orally once daily for a duration of 24 weeks. Approximately 114 subjects will be enrolled, including an estimated 20% dropout rate, with 38 subjects assigned to each group (Treatment Group 1, Treatment Group 2, and Control Group). The objectives of the study are as follows: 1. Efficacy Objectives: Efficacy will be evaluated through changes in cognitive function, self-management, and daily living activities before and after administration of KDS2010. Biomarker analysis in plasma and in cerebrospinal fluid (CSF; optional) will also be conducted to explore treatment efficacy. 2. Safety Objectives: The safety and tolerability will be evaluated after administration of KDS2010. 3. Exploratory Objectives: The efficacy of Treatment Groups 1 and 2 compared to the Control group will be explored through cognitive endpoints (the Clinical Dementia Rating-Sum of Boxes (CDR-SB), the Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog13), and the Mini-Mental State Examination (MMSE)), stratified by demographic information, tauopathy, and ApoE4 genes. Based on nonclinical and Phase 1 clinical data, KDS2010 will be administered orally once daily at two dose levels: 60 mg and 120 mg.
