Outcome Measures

Primary Outcomes (12)

  • To determine the safety and tolerability multiple subcutaneous doses of MD-18 in overweight or obese but otherwise healthy subjects, as assessed by the collection of Adverse events.

    All adverse events, exacerbations of concomitant illnesses, or events known to be related to underlying disease processes or concomitant medications are to be recorded on the case report form throughout the study. Should there be more than 2 subjects receiving MD-18 with an adverse event grade 4 or 5 that is at least possibly related to MD-18, the study will be put on immediate hold and the data will be reviewed by the site Principal Investigator (PI) and the company Chief Medical Officer (CMO) before proceeding.

    Through study completion, an average of 8 months

  • To determine the safety and tolerability multiple subcutaneous doses of MD-18 in overweight or obese but otherwise healthy subjects, as assessed by the collection of body temperature.

    Body temperature measurements in Celsius (°C) will be conllected at the visits specified in the study protocol's Schedule of Events. If any clinically significant findings or machine/equipment errors occur, the measurement will be repeated. Any confirmed clinically significant result will be recorded as adverse events (AEs).

    During the following study visits: Screening, Day 1,7,14,21,28 and 35) and at the study visits of the 8 weeks study extension period on days 42,56,70,84 and 92 (Only for subjects that have agreed to participate from Cohort 7)

  • To determine the safety and tolerability multiple subcutaneous doses of MD-18 in overweight or obese but otherwise healthy subjects, as assessed by the collection of Serum chemistry.

    Collection of blood samples for serum chemistry

    During the screening visit, Day 1, 7,28,35 and at the study visits of Day 56,84 and 92 at the 8 weeks study extension period (Only for subjects that have agreed to participate from Cohort 7).

  • To determine the safety and tolerability multiple subcutaneous doses of MD-18 in overweight or obese but otherwise healthy subjects, as assessed by the collection of body weight

    Body weight (in kilograms) will be measured. To ensure consistency and accuracy, all subjects will be measured while wearing only undergarments or light clothing, without shoes. A calibrated scale will be used consistently throughout the study. In addition, weight measurements along with the screening height measurement will be combined to report BMI in kg/m\^2

    During each study visit and at the study visits of the 8 weeks study extension period (Only for subjects that have agreed to participate from Cohort 7)

  • To determine the safety and tolerability multiple subcutaneous doses of MD-18 in overweight or obese but otherwise healthy subjects, as assessed by the collection of Electrocardiogram examination.

    12-lead triplicate ECGs will be obtained. The ECG machine will automatically calculate the following: Heart rate ( refers to the number of contractions of the heart per minute) PR interval (PR interval is the time from the beginning of the P wave (atrial depolarization) to the beginning of the QRS complex. QRS complex (represents the depolarization of ventricles And the beginning of systole and ventricular contraction). QT interval (is the time from the beginning of the QRS complex, representing ventricular depolarization, to the end of the T wave, resulting from ventricular repolarization). QTc interval (is the QT interval corrected for heart rate).

    at screening (visit 1; Day -7) and days 7, 28 and 35. On Day 92 (for the 8 weeks extension period Only for subjects that have agreed to participate from Cohort 7).

  • To determine the safety and tolerability multiple subcutaneous doses of MD-18 in overweight or obese but otherwise healthy subjects, as assessed by the collection of respiration rate

    Respiration rate in breaths per minute will be collected at the visits specified in the study protocol's Schedule of Events. If any clinically significant findings or machine/equipment errors occur, the measurement will be repeated. Any confirmed clinically significant result will be recorded as adverse events.

Masking Details
Study medication will be supplied in labelled vials,clearly identifying the contents and indicating that the product is an investigational drug. An unblinding pharmacist at the clinical site will be responsible for the appropriate amount of vials to be dispnsed to each subject according to the randomization scheme. A blinded nurse will draw the correct amount of study medication into a syringe based on the subject's assigned arm, and administer the injection to the subject.
Purpose
TREATMENT
Intervention Model
SEQUENTIAL
Model Details: Dosing will be in 7 dose cohorts. Cohorts 1 through 6 will be comprised of six subjects in each cohort using 4:2 (active: placebo) randomization. Thus, there will be four subjects receiving drug and two receiving placebo in each cohort. Cohort 7 will comprise 18 Obese subjects, in which 12 subjects will receive MD-18 and six will receive placebo. A total of 54 subjects will be enrolled in this study, with 36 receiving MD-18 and 18 receiving placebo. There is no need to wait for the completion of one cohort (Day 28) before proceeding to the next. Once all subjects for Cohort 1 have been recruited, the site should begin recruitment for Cohort 2, even while Cohort 1 is still ongoing. This process should continue for subsequent cohorts. The highest dose that is safe and tolerable in all subjects will be determined as the Maximum Tolerable Dose .
