- 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.
- 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 sampling.
- Participants fill out a 2-page survey asking about why they did or did not participate in the study's PK sampling.
Pharmacokinetic studies provide critical information about the disposition of anticancer drugs in children. However, participation of children in the pharmacokinetic portion of phase I studies is optional when there is not prospect of direct benefit to the child.
The rate of participation in optional PK studies on COG Phase I Consortium Studies has been 60-70%.
There are no recent data on why families do or do not agree to participate in optional PK studies. Understanding families' reasons may reveal barriers to participation that could be overcome, leading to increased participation rates in optional PK sampling.
To use a simple 2 page survey to gather preliminary information on why parents/children agree to participate in Phase I Studies do or do not agree to participate in the voluntary pharmacokinetic (PK) portion of those studies.
Subjects (greater than or equal to 18 years old) or parents/guardians of subjects who are minors who consented to Phase I studies with optional PK sampling with the previous 4 weeks.
Consent for the primary Phase I treatment protocol must be active (not withdrawn).
No limit on the number of prior Phase I studies in which the subject or subject's child participated.
Subjects may only participate in this study once.
The individual who provided consent to the treatment study that included optional PK sampling will complete a short questionnaire.
Subjects (n=50) from a convenience sample will complete and return the questionnaire.
Reasons for participating or agreeing to participate will be tabulated. Correlations between answers and subject demographics, time required by PK, need for additional IV will be sought.
Subjects will meet off study criteria when the questionnaire is returned, lost to follow up, or consent for data submission to this or the primary treatment protocol is withdrawn.
The total accrual is 50 subjects. Accrual ceiling at the POB, NCI is 25 subjects.

An alkylating agent of value against both hematologic malignancies and solid tumors.
A smooth, solid or cystic fibroepithelial (FIBROEPITHELIAL NEOPLASMS) tumor, usually found in the OVARIES but can also be found in the adnexal region and the KIDNEYS. It consists of a fibrous stroma with nests of epithelial cells that sometimes resemble the transitional cells lining the urinary bladder. Brenner tumors generally are benign and asymptomatic. Malignant Brenner tumors have been reported.
A complex of related glycopeptide antibiotics from Streptomyces verticillus consisting of bleomycin A2 and B2. It inhibits DNA metabolism and is used as an antineoplastic, especially for solid tumors.
A group of methylazirinopyrroloindolediones obtained from certain Streptomyces strains. They are very toxic antibiotics used as ANTINEOPLASTIC AGENTS in some solid tumors. PORFIROMYCIN and MITOMYCIN are the most useful members of the group.
A complex of several closely related glycosidic antibiotics from Streptomyces griseus. The major component, CHROMOMYCIN A3, is used as a fluorescent stain of DNA where it attaches and inhibits RNA synthesis. It is also used as an antineoplastic agent, especially for solid tumors.
