19
Q

What is the most common dosing recommendation for pediatric patients?

A

Dosing recommendations for most medicinal products used in the pediatric population are usually based on milligram (mg)/kilogram (kg) body weight up to a maximum adult dose.

20
Q

Why is mg/square meter body surface not used for dosing recommendations?

A

While dosing based on mg/square meter body surface area might be preferred, clinical experience indicates that errors in measuring height or length (particularly in smaller children and infants) and calculation errors of body surface area from weight and height are common

21
Q

What other type of dosing may be necessary in pediatric populations? E.g medications with a narrow therapeutic index

A

surface-area-guided dosing may be necessary, but extra care should be taken to ensure proper dose
calculation

22
Q

True or False?

The volume of blood withdrawn should be minimized in pediatric studies.

A

True

23
Q

Do blood volume withdrawls have to be in the protocol?

A

Yes

24
Q
Can Institutional Review Boards/Independent
Ethics Committees (IRB’s/IEC’s) review and may define the maximum amount of blood?
A

Yes- (usually on a milliliters (mL)/kg or percentage of total blood volume basis) that may be taken for investigational purposes.

25
Q

List of approaches used to minimize amount of blood withdrawn and/or number of venipunctures?

A
  • Use of sensitive assays for parent drugs and metabolites to decrease the volume of blood required per sample
  • Use of laboratories experienced in handling small volumes of blood for pharmacokinetic analyses and for laboratory safety studies (blood counts, clinical chemistry)
  • Collection of routine, clinical blood samples wherever possible at the same time as samples are obtained for pharmacokinetic analysis
  • The use of indwelling catheters, etc., to minimize distress as discussed in section 2.6.5.
  • Use of population pharmacokinetics and sparse sampling based on optimal sampling theory to minimize the number of samples obtained from each patient.

Techniques include:
-Sparse sampling approaches where each patient contributes as few as 2 to 4 observations at predetermined times to an overall “population area under-thecurve”

-Population pharmacokinetic analysis using the most useful sampling time points derived from modeling of adult data

26
Q

Which of the following apply to pediatric patients?

A. The principles in study design, statistical considerations and choice of control groups
detailed in ICH E6, E9, and E10 generally apply to pediatric efficacy studies

B. ICH guidances on E2 topics and ICH E6, which describe adverse event reporting,
apply to pediatric studies

A

Both

27
Q

True or False?

Medicinal products may affect physical and cognitive growth and development, and the adverse event profile may differ in pediatric patients.

A

True

28
Q

Describe the age range categories given in this ICH

5 of them

A

Preterm newborn infants

Term newborn infants (0 to 27 days)

Infants and toddlers (28 days to 23 months)

Children (2 to 11 years)

Adolescents (12 to 16-18 years (dependent on region))

29
Q

What important features should be considered in Preterm Newborn Infants?

A

(1) gestational age at birth and age after birth (adjusted age);
(2) immaturity of renal and hepatic clearance mechanisms;
(3) protein binding and displacement issues (particularly bilirubin);
(4) penetration of medicinal products into the central nervous system (CNS);
(5) unique neonatal disease states (e.g., respiratory distress syndrome of the newborn, patent ductus
arteriosus, primary pulmonary hypertension);
(6) unique susceptibilities of the preterm newborn (e.g., necrotizing enterocolitis, intraventricular hemorrhage, retinopathy of prematurity);
(7) rapid and variable maturation of all physiologic and
pharmacologic processes leading to different dosing regimens with chronic exposure;
(8) transdermal absorption of medicinal products and other chemicals

30
Q

What study design issues should be considered in Preterm Newborn Infants?

A

(1) weight and age (gestational and postnatal) stratification;
(2) small blood volumes (a 500-g infant has 40 mL of blood);
(3) small numbers of patients at a given center and differences in care among centers;
and
(4) difficulties in assessing outcomes.

31
Q

True or False?

Oral absorption of medicinal products may
be less predictable in Term Newborn infants than in older pediatric patients

A

trueeeeeeee

32
Q

Does oral asorption become more reliable in infants and toddlers then newborns and preterms?

A

Yes

33
Q

In children, what can puberty affect?

A

Puberty can affect the apparent activity of enzymes that metabolize drugs, and dose requirements for some medicinal products on a mg/kg basis may decrease dramatically (e.g., theophylline)

34
Q

In what age group is non-compliance a problem?

A

LOL adolescents

35
Q

True or False?

When protocols involving the pediatric population are
reviewed, there should be IRB/IEC members or experts consulted by the IRB/IEC who are knowledgeable in pediatric ethical, clinical, and psychosocial issues

A

True

36
Q

Is this true? As a rule, a pediatric subject is legally unable to provide informed consent. Therefore
pediatric study participants are dependent on their parent(s)/legal guardian to assume responsibility for their participation in clinical studies.

A

True

37
Q

Fully informed consent should be obtained from the __ _____ in accordance with regional laws or regulations

A

Legal Guardian

38
Q

Where appropriate, participants should ________ to enroll in a study (age of assent to be determined by
IRB’s/IEC’s or be consistent with local legal requirements).

A

assent

39
Q

True or False?
Participants of appropriate intellectual maturity should personally sign and date either a separately
designed, written assent form or the written informed consent.

A

True

40
Q

Emancipated or mature minors (defined by local

laws) are not capable of giving autonomous consent.

A

False-they are

41
Q

Practical considerations to ensure that participants’ experiences in clinical studies are positive and to minimize discomfort and distress include the following:

A
  • Personnel knowledgeable and skilled in dealing with the pediatric population and its age-appropriate needs, including skill in performing pediatric procedures
  • A physical setting with furniture, play equipment, activities, and food appropriate for age
  • The conduct of studies in a familiar environment such as the hospital or clinic where participants normally receive their care

Approaches to minimize discomfort of procedures, such as:

  • Topical anesthesia to place IV catheters
  • Indwelling catheters rather than repeated venipunctures for blood sampling
  • Collection of some protocol-specified blood samples when routine clinical samples are obtained
42
Q

__________should consider how many venipunctures are acceptable in an attempt to obtain blood samples for a protocol and ensure a clear understanding of procedures if an indwelling catheter fails to function over time.

A

IRB’s/IEC

43
Q

Of all the factors to determine to proceed with a pediatric study, what is the most important?

A

The most important is the presence of a serious or life-threatening disease for which the medicinal product represents a potentially important advance in therapy.

This situation suggests relatively urgent and early initiation of pediatric
studies.
