Inflation of Type I Error in the Evaluation of Scaled Average Bioequivalence, and a Method for its Control.

Purpose: To verify previously reported findings for the European Medicines Agency's method for Average Bioequivalence with Expanding Limits (ABEL) for assessing highly variable drugs and to extend the assessment for other replicate designs in a wide range of sample sizes and CVs. To explore the properties of a new modified method which maintains the consumer risk ≤0.05 in all cases.

Influence of acarbose on blood glucose and breath hydrogen after carbohydrate load with sucrose or starch.

A monocentric, open, randomised, single-dose, six-period crossover trial was carried out in healthy volunteers under fasting conditions to establish the most appropriate study design for a pivotal bioequivalence trial with acarbose (CAS 56180-94-0) regarding a) dosage of the drug, b) type of carbohydrate load, c) type of primary endpoint, and d) sample size. 50 g sucrose or 50 g starch were used as carbohydrate load. Acarbose was administered in doses of 50 and 200 mg.

Bioequivalence study of two different clopidogrel bisulfate film-coated tablets.

Objective: The aim of the present study was to evaluate the bioequivalence of two oral clopidogrel (CAS 113665-84-2) formulations.

Method: The study was conducted as a monocentric, open, randomized, single-dose, two-period crossover trial in 48 healthy volunteers with a duration of hospitalization of approximately 24 h after dosing on day 1 and with a real wash-out period of 7 days. Blood samples were collected for 24 h post dosing in each period.
