Study summary

The aim of this 4-weeks randomized double-blind placebo-controlled single and multiple ascending dose study is to assess the Safety and Tolerability of LB54640 in Healthy overweight and obese subjects

Read the detailed description

The study was conducted in 2 parts:

Part 1 (Single Ascending Dose) This study part included 6 sequential dose cohorts (S1-S6), enrolling 8 healthy subjects per cohort. Cohort S3 was evaluate the effect of food.

Part 2 (Multiple Ascending Dose) This part included 7 sequential dose cohorts (M1-M7), enrolling 8 subjects per cohort. Cohorts was evaluate safety, Pharmacokinetics and Pharmacodynamics parameters in healthy overweight and obese subjects. They were dosed once daily for 28 days with LB54640 or placebo.

What researchers measure

Primary outcomes

  1. Incidence and severity of adverse events (AEs)

    Number of subjects who experienced adverse events and severity of adverse events

    Time frame: Through study completion upto 6weeks depending on cohorts

  2. Incidence and severity of adverse events of special interest (AESIs) in Part 2 (MAD)

    Number of subjects who experienced adverse events of special interest (AESIs)

    Time frame: Through study completion upto 6weeks depending on cohorts

  3. Change from baseline in vital signs (blood pressure)

    Absolute values and changes from baseline (BP assessed by 24-hour ambulatory blood pressure monitoring (ABPM);systolic pressure and diastolic pressure will be assessed

    Time frame: Through study completion upto 6weeks depending on cohorts

  4. Change from baseline in vital signs (heart rate)

    Absolute values and changes from baseline (HR assessed by 24-hour ambulatory electrocardiography monitoring (12-lead cardiac telemetry; central reader))

    Time frame: Through study completion upto 6weeks depending on cohorts

  5. Change from baseline in vital signs (weight in kilograms, height in meters)

    weight and height will be combined to report BMI in kg/m\^2

    Time frame: Through study completion upto 6weeks depending on cohorts

Secondary outcomes

  1. Pharmacokinetics profiles in Plasma for single ascending dose cohort
