About

Primary Objectives:

• Main study: To assess in overweight to obese subjects and type 2 diabetes mellitus (T2DM) patients not requiring anti-diabetic pharmacotherapy the safety and tolerability of 3 different dose escalation regimens of SAR425899 in terms of the relative and absolute frequency and severity of gastrointestinal (GI) adverse events (AEs).
• Six-month safety extension period: To assess the safety and tolerability of SAR425899 after 6 months treatment at the maximum dose that was individually well tolerated during the main part of the study in terms of the relative and absolute frequency and severity of GI AEs.

Secondary Objectives:

Main study and 6-month study extension period:

To assess in overweight to obese subjects and T2DM patients not requiring anti-diabetic pharmacotherapy:

• The effect of once-daily dosing of SAR425899 on body weight (BW), fasting plasma glucose (FPG), and hemoglobin A1c (HbA1c).
• Safety and tolerability.

Full description

Main study: The maximum study duration is approximately 12 weeks per patient (up-to 3-week screening period, 8-week treatment period, 3-day post treatment follow-up period).

Six-month study extension period: The maximum study duration is approximately 9 months (up-to 3-week screening period, 8-month treatment period, 3-day post treatment follow-up period).

Enrollment: 60 patients

Sex: All

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: None (Open label)

---

60 participants in 3 patient groups

Cohort 1

Experimental group

Description:

Daily dose escalation (click-by-click): Starting at dose 1 in the morning with daily increments to dose 2. During the escalation phase, the dose will only be increased if the patient is feeling fine.

Treatment:

Drug: SAR425899

Cohort 2

Experimental group

Description:

Weekly dose escalation in 6 escalation steps (7 dose levels): Starting at dose 1 injected in the morning with weekly increments to dose 2. In case a dose level is not well tolerated by a patient, the treatment should continue at the same dose level for another 7 days before the next dose escalation.

Treatment:

Drug: SAR425899

Cohort 3

Experimental group

Description:

Weekly dose escalation in 4 escalation steps (5 dose levels): Starting at dose 3 with weekly increments to dose 2. In case a dose level is not well tolerated by a patient, the treatment should continue at the same dose level for another 7 days before the next dose escalation.
