- A pharmacokinetic (PK) study of a new drug involves taking several blood samples over a
period of time from study participants to determine how the body handles the substance.
These studies provide critical information about new drugs.
- Often, patients or parents of children in drug studies choose not to participate in
optional PK studies that are part of the study protocol.
- A better understanding of why patients or families do or do not agree to participate in
PK studies may help researchers make it easier for people to participate in them.
- To learn why some people do or do not agree to participate in PK blood sampling studies.
- Patients 18 years of age and older and parents or guardians of children who are
participating in a study of a drug that includes the option of participating in PK
- Participants fill out a 2-page survey asking about why they did or did not participate
in the study's PK sampling.
