(i)

section 355 of this title under for a new active ingredient, new indication, new dosage form, new dosing regimen, or new route of administration; or

(ii)

section 262 of title 42 under for a new active ingredient, new indication, new dosage form, new dosing regimen, or new route of administration,

(i)

intended for the treatment of an adult cancer; and

(ii)

directed at a molecular target that the Secretary determines to be substantially relevant to the growth or progression of a pediatric cancer.

(2)

Assessments

(A)

In general

The assessments referred to in paragraph (1)(A) shall contain data, gathered using appropriate formulations for each age group for which the assessment is required, that are adequate—

(i)

to assess the safety and effectiveness of the drug or the biological product for the claimed indications in all relevant pediatric subpopulations; and

(ii)

to support dosing and administration for each pediatric subpopulation for which the drug or the biological product is safe and effective.

(B)

Similar course of disease or similar effect of drug or biological product

(i)

In general

If the course of the disease and the effects of the drug are sufficiently similar in adults and pediatric patients, the Secretary may conclude that pediatric effectiveness can be extrapolated from adequate and well-controlled studies in adults, usually supplemented with other information obtained in pediatric patients, such as pharmacokinetic studies.

(ii)

Extrapolation between age groups

A study may not be needed in each pediatric age group if data from one age group can be extrapolated to another age group.

(iii)

Information on extrapolation

(3)

Molecularly targeted pediatric cancer investigation

(A)

In general

With respect to a drug or biological product described in paragraph (1)(B), the investigation described in this paragraph is a molecularly targeted pediatric cancer investigation, which shall be designed to yield clinically meaningful pediatric study data, gathered using appropriate formulations for each age group for which the study is required, regarding dosing, safety, and preliminary efficacy to inform potential pediatric labeling.

(B)

Extrapolation of data

Paragraph (2)(B) shall apply to investigations described in this paragraph to the same extent and in the same manner as paragraph (2)(B) applies with respect to the assessments required under paragraph (1)(A).
