About this study

Official title: A Randomized, Double-blind, Placebo-controlled, Dose Finding, Phase 2a Clinical Trial to Evaluate the Efficacy and Safety of KDS2010 in Overweight or Obese Patients

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.

Read more

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.

Read the detailed description

This Phase 2a, randomized, double-blind, placebo-controlled, dose-finding clinical trial is designed to evaluate the efficacy, safety, and pharmacokinetics of KDS2010, a novel, reversible monoamine oxidase-B (MAO-B) inhibitor, in overweight or obese adult patients. The clinical trial is conducted at selected sites in Korea.

The study consists of three stages and will enroll approximately 75 subjects. In Stage 1, 9 subjects were randomized in a 2:1 ratio (KDS2010 120 mg: placebo) to evaluate initial safety and tolerability. Upon completion of the week 13 visit for the last subject in Stage 1, a Safety Review Committee (SRC) assessed cumulative safety data and determined that the study may proceed to Stage 2.

Stage 2 is currently being prepared for subject recruitment and will proceed with 33 subjects randomized in a 2:1 ratio to receive KDS2010 180 mg or placebo. Upon completion of the Week 13 visit for the last ongoing subject in Stage 2, the SRC will review the safety data collected up to that time to determine whether the study may proceed to Stage 3. Stage 3 will proceed with 33 subjects randomized in a 2:1 ratio to receive KDS2010 240 mg or placebo.

All subjects will undergo a 2-week run-in period prior to randomization to confirm eligibility based on adherence to lifestyle modification (documented reduction of ≥500 kcal/day and ≥150 minutes of physical activity per week for ≥50% of the run-in period).

The treatment period consists of 12 weeks of once-daily oral administration of the investigational product (IP), followed by a 1-week post-treatment safety follow-up (week 13). During treatment, subjects will visit the site at Weeks 4, 8, and 12, with a telephone visit at Week 2. Safety follow-up will be conducted by phone at Week 13.

The primary efficacy endpoint is the percentage change in body weight from baseline to Week 12. Secondary efficacy endpoints include the proportion of subjects achieving ≥5%, ≥10%, ≥15%, and ≥20% weight loss and changes in waist circumference, BMI, blood pressure (SBP/DBP), quality of life (IWQOL-Lite-CT), body composition (DEXA), lipid profile, glycemic parameters (HbA1c, fasting glucose, HOMA-IR), and liver steatosis. Exploratory endpoints assess the proportion of subjects with ≥25% weight loss, as well as changes in MAO-B specific activity and adiponectin levels.

Safety will be evaluated through monitoring of adverse events (AEs), laboratory tests, vital signs, ECGs, and psychological assessments, including the Columbia-Suicide Severity Rating Scale (C-SSRS) and Patient Health Questionnaire-9 (PHQ-9). Pharmacokinetic parameters (AUCtau, Cmax,ss, Cmin,ss, Cav,ss, Tmax,ss, t1/2, PTF, etc.) will be measured to assess systemic exposure to KDS2010.

Subjects must be adults aged 19 years or older, have a BMI ≥30 kg/m² or ≥27 kg/m² with at least one weight-related comorbidity, and demonstrate compliance with lifestyle modification during the run-in.

Major exclusion criteria include recent significant weight change (≥5% within 12 weeks), use of anti-obesity drugs or MAO inhibitors, type 1 or 2 diabetes, bariatric surgery, uncontrolled hypertension, hepatic or renal dysfunction, significant psychiatric disorders, or suicidal ideation/attempts.

The total study duration is expected to be approximately 28 months from IRB approval, with individual subject participation lasting up to 17 weeks. This trial aims to evaluate the safety, efficacy, and pharmacokinetics of KDS2010 for future development in the treatment of obesity.

    Measured: Baseline to Week 12

  2. Change from baseline in Waist Circumference

    Waist circumference will be measured to the nearest 0.1 cm using a tape measure while the participant stands with feet approximately 25-30 cm apart, distributes body weight evenly, and exhales comfortably. Changes will be assessed up to Week 12.

    Measured: Screening(Week -4 to -2), Run-in(Week -2), Baseline(Week 0), Week 4, 8, 12

  3. Change from baseline in Body Mass Index (BMI)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing KDS2010 in people with Overweight and Obesity, run by NeuroBiogen Co., Ltd at 3 sites in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 41 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 24 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Jaeheon Kang, Professor (+82)2-6959-9927, jenny.kim@mdnf.co.kr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage Change in Body Weight from Baseline (time frame: Baseline to Week 12). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jun 2026.
