From: Three steps to writing adaptive study protocols in the early phase clinical development of new medicines

Adaptive study design category

Boundaries

Assessments

1. Safety/tolerability samples and assessments (such as safety laboratory, vital signs, electrocardiograms (ECGs), continuous cardiac monitoring etc.) &

1. Minimum data requirements for progression between dosing regimens/protocol parts

2. PK/PD/exploratory/other samples and assessments:

2. Defined sampling or assessment types/categories for which adaptability is permitted

a) Additional or less samples or assessments may be taken

3. Minimum samples/time-points/assessments to sufficiently cover the full safety/tolerability and PK/PD profile in relation to relevant doses (e.g. single dose, steady state)

b) Timing of samples or assessments may be adapted

4. Maximum

 

-blood (or other) volumes

 

-number of samples or assessments

 

-sampling or assessment time-points

Assessments

3. Prolongation or shortening of the in-house period or out-patient follow-up period

1. Minimum/maximum in-house stay or out-patient follow-up periods based on:

 

-study specific safety & tolerability, PK and/or PD parameters that must be reached prior to discharge from the clinic/study

 

-evolving safety and tolerability profile of the IMP

 

-and evolving PK/PD characteristics of the IMP up to the decision making time-point
