Brief summary
This single-dose, randomized, open label, five-treatment, five-period, five-sequence crossover study was performed to assess pharmacodynamics (PD) and pharmacokinetics (PK) of three new developed coated Glucose beads formulations (containing glucose (8 g) and caffeine), one coated Glucose beads formulation (containing glucose (8 g)) and one uncoated Glucose beads formulation (containing Glucose (8 g) and caffeine) after single-dose administration (fasting conditions) in 20 obese healthy subjects. After an overnight fasting of at least 10 hours the subjects were administered either glucose (8 g) or glucose (8 g) and caffeine starting at 8:00 (time 0; administration time was staggered beginning at 8:00 for the first group of subjects) in sitting position. At least 3 days wash-out period was kept between each treatment periods.
Detailed description
This single-dose, randomized, open label, five-treatment, five-period, five-sequence crossover study was performed to assess pharmacodynamics (PD) and pharmacokinetics (PK) of three new developed coated Glucose beads formulations (containing glucose (8 g) and caffeine), one coated Glucose beads formulation (containing glucose (8 g)) and one uncoated Glucose beads formulation (containing Glucose (8 g) and caffeine) after single-dose administration (fasting conditions) in 20 obese healthy subjects. Only subjects who had given voluntarily their informed consent participated in the screening examination and, if found eligible as per study inclusion and exclusion criteria, were enrolled in the study. At least 13 hours before investigational product administration in each treatment period, subjects were admitted to the clinical site. During each treatment period the hospitalization period in the clinical unit was 13 hours before and up to 11 hours after investigational product administration. Test products (T1, T 2, T3, T4, T5) was administered as single oral doses during the first, second, third, fourth and fifth treatment period corresponding to the randomization code under fasting conditions. After an overnight fasting of at least 10 hours, the subjects were administered either glucose (8 g) or glucose (8 g) and caffeine starting at 8:00 (time 0; administration time was staggered beginning at 8:00 for the first group of subjects) in sitting position. According to the randomization code subjects were received on the respective study day one coated beads formulations (T1, T2, T3, T 4) or the uncoated beads formulation (T5). A total of 17 blood samples were drawn for determination of Glucagon-like peptide-1 (GLP-1) levels and pharmacokinetic analysis of caffeine at the prescribed times, pre-dose (1.0 h, 0.5 hand 0 h) and 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 8.0 and 10.0 hours after investigational product administration. Blood samples for glucose measurements was taken via an indwelling catheter or vein puncture from the forearm vein pre-dose (1.0 h, and 0 h) and at 0.5, 1.0, 2.0, 3.0, 4 0, 5.0, 6 0, 8.0 and 10.0 hours after investigational product administration. Visual analogue scale (VAS) (appetite), VAS (stomach rumbles) were evaluated at the prescribed times pre-dose (0 h) and at 2, 4 and 10 hours after investigational product administration. Wash-out periods of at least 3 days were separated the five treatment periods. Within 7 days after last blood sampling in the last treatment period 12-lead electrocardiogram (ECG), vital signs, clinical routine laboratory parameters, physical examination and check of adverse events were repeated.
Interventions
DRUGcoated beads glucose (8 g) and caffeine anhydrous
After an overnight fasting of about 10 hours the subjects were administered either glucose (8 g) or glucose (8 g) and caffeine starting at 8:00 (time 0; administration time was staggered beginning at 8:00 for the first group of subjects) in sitting position on Day 1.
DRUGcoated beads glucose (8 g)
After an overnight fasting of about 10 hours the subjects were administered glucose (8 g) starting at 8:00 (time 0; administration time was staggered beginning at 8:00 for the first group of subjects) in sitting position on Day 1.
DRUGuncoated beads glucose (8 g) and caffeine anhydrous
After an overnight fasting of about 10 hours the subjects were administered either glucose (8 g) or glucose (8 g) and caffeine starting at 8:00 (time 0; administration time was staggered beginning at 8:00 for the first group of subjects) in sitting position on Day 1.
