Accepts healthy volunteers: yes
Allocation: RANDOMIZED
Intervention model: SEQUENTIAL
Intervention model description: 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 .

Brief summary: A Multiple Dose, Randomized, Placebo-controlled, Dose-escalating Study to Evaluate Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Subcutaneously Administered MD-18 for healthy subjects with overweight or obesity

Detailed description: This study will be conducted as a single center study, at the Sheba Medical Center, Israel. Escalating daily doses of MD-18 or placebo will be administered subcutaneously to each subject over a 4-week period with a 7-day follow-up period. 54 patients will be enrolled across 7 cohorts. Each of the cohorts will enroll 4 active and two placebo subjects, except for the final cohort. Cohort 7 will be comprised of obese subjects and will enroll 12 active and 6 placebo subjects. Starting dose has been determined from the SAD study (CG MD-18-01). Cohorts will receive 74 mg MD-18 three times weekly, (starting dose), 114 mg three times weekly, 227 mg three times weekly, 302 mg once weekly, 302 mg three times weekly or 302 mg daily using 4:2 (active:placebo) randomization; all doses refer to the MD-18 salt. A total of 36 subjects will receive active therapy across seven cohorts (24 in the first six cohorts and 12 in the seventh cohort) and 18 subjects will receive placebo. The study will be conducted on an outpatient basis, with visits performed as shown in the schedule of events.
