In vivo Trial Arms (TA) Domain Model

Example: Simple Parallel Design, No Recovery

TOBA-211 - Getting issue details... STATUS TOBA-212 - Getting issue details... STATUS This example assumes a simple parallel design in which the applicant-defined protocol specifies the following information. All subjects are to be screened for 7 days prior to randomization into 3 protocol groups:

Group 1 is a control group of 20 subjects, 10 male and 10 female, dosed with vehicle once per day for 28 days.
Group 2 is a low-dose group of 20 subjects, 10 male and 10 female, dosed at 100 mg/kg once per day for 28 days.
Group 3 is a high-dose group of 20 subjects, 10 male and 10 female, dosed at 500 mg/kg once per day for 28 days.

There are no other experimental factors of interest specified in the study design. In this case, the design consists of 3 trial arms, because there are 3 distinct sequences of elements, depicted as follows:
