ADVL08N1: A Pharmacokinetic Participation Questionnaire Study

Background:

• 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.

Objectives:

• To learn why some people do or do not agree to participate in PK blood sampling studies.

Eligibility:

• 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 sampling.

Design:

• Participants fill out a 2-page survey asking about why they did or did not participate in the study's PK sampling.
