About
The Sponsor, Genfit, has developed a new formulation of GFT505 (60 mg). The objective is to compare the relative bioavailability between the new GFT505 formulation (capsule dosed at 60 mg GFT505) and the old GFT505 formulation (capsule dosed at 20 mg GFT505) in healthy male subjects and to assess the impact of gender on this relative bioavailability after administration in male and female subjects.
Using the new formulation, a single and a multiple ascending dose study will be performed in overweight or obese male subjects otherwise healthy whose demographic and physiological characteristics are thought to be closer to those of the target population (Type 2 diabetes). Thereafter, a group of male and female patients with Type 2 diabetes will receive multiple dose administration of GFT505.
Full description
The study will be divided in 4 successive parts :
- Study Part I will be a comparative bioavailability between a new GFT505 formulation (capsule dosed at 60 mg GFT505 by capsule) and the old GFT505 formulation (capsule dosed at 20 mg GFT505 by capsule) coupled with an evaluation of the gender effect assessed with the new formulation. In this purpose a group of 12 male subjects will receive successively both formulations on a unique occasion in a randomized manner while a group of 12 female subjects will receive the new formulation on one occasion only. This part of the study will be done in healthy volunteers.
- Study Part II will be a single ascending dose to be run at a maximum of 3 dose levels. Subjects included in this part of the study will receive only one dose level to limit the exposure to GFT505. Three cohorts of 8 subjects are planned to be included. This part will be run in overweight or obese subjects.
- Study Part III will start after completion of the first Cohort of Study Part II. Study Part III will be a multiple ascending dose to be run at a maximum of 3 dose levels. Subjects included in this part of the study will receive only one dose level to limit the exposure to GFT505. Three cohorts of 12 subjects are planned to be included. This part will be run in overweight or obese subjects.
- Study Part IV will follow the same design and same treatment schedule than Study Part III but will be performed in the target population, patients with Type 2 diabetes and only one dose will be tested in study part IV.

Exclusion criteria
Part I :
- Who previously received GFT505.
- With any clinically significant abnormality following review of prestudy laboratory tests (Aspartate and Alanine aminotransferase must be within normal ranges), vital signs, full physical examination and Electrocardiogram.
- Who have a positive laboratory test for Hepatitis B surface antigen (HbsAg), or anti-HIV 1/2 (Human immunodeficiency virus) or anti-HCV (Hepatitis C virus) antibodies.
- Who are known or suspected alcohol or drug abusers (more than 14 units of alcohol per week, one unit = 8 g or about 10 mL of pure alcohol).
- Who drink more than 8 cups daily of beverage containing caffeine.
- Who have a positive laboratory test for urine drug screening (opiates, cocaine, amphetamine, cannabis, benzodiazepines).
- Who have undergone surgery or have donated blood within 12 weeks prior to the start of the study.
- Who have taken any prescribed or over the counter drug (including antacid drug), with the exception of paracetamol (up to 3 g per day) within 2 weeks prior to the first dose administration.
Part II and III : specific additional exclusion criteria
- Who have taken fibrates within 6 weeks prior to the first dose administration.
Part IV : specific additional exclusion criteria
- With unstable proliferative retinopathy, macular oedema (fundus examination performed in the previous year will be considered relevant on Investigator's judgement).
- Who have taken fibrates within 6 weeks prior to the first dose administration.
