SEND Example.In vivo Example Trial 2

This example assumes a design in which the sponsor-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 to 30 days. Three subjects of each sex will be subject to blood sampling for the purpose of toxicokinetic (TK) analysis and all remaining animals will be scheduled for necropsy.
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 to 30 days. Three subjects of each sex will be subject to blood sampling for the purpose of TK analysis and all remaining animals will be scheduled for necropsy.
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 to 30 days. Three subjects of each sex will be subject to blood sampling for the purpose of TK analysis and all remaining animals will be scheduled for necropsy.

Group Number	Group Label	Dose Level	Number of Animals (Both Sexes Combined)
Group Number	Group Label	Dose Level	Non-Toxicokinetic	Toxicokinetic
1	Group 1, Control	Vehicle Control	14	6
2	Group 2, 100 mg/kg	100 mg/kg/day	14	6
3	Group 3, 500 mg/kg	500 mg/kg/day	14	6

There are no other experimental factors of interest specified in the study design. In this case the design consists of 3 trial arms, depicted in the following figure.

Trial Elements

In this study, treatment started on one date and the necropsy is scheduled, for an individual animal, after 28 to 30 days of treatment. The necropsy for a subset of animals per treatment per day will be staggered over a 3-day period.

Trial Arms

There are three trial arms in this study. The fact that some subjects are being selected for blood sampling is an experimental factor that is separate from the treatment being received; this is described in the TS example.

Trial Sets

Assuming that the protocol also specifies that subjects with blood sampling for TK analysis are experimentally distinct, the factors of interest are the treatment levels and whether the subject is sampled for TK analysis; this leads to 6 trial sets.

The sponsor has chosen to provide the associated arm code, sponsor-defined group code, group label, set label, dose level and units, control type, whether the trial set is being sampled for TK analysis, and planned number of males and females for each set.
