Except with respect to an application for which subparagraph (B) applies, a person that submits, on or after

September 27, 2007
, an application (or supplement to an application) for a drug—

(i)

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

(ii)

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

shall submit with the application the assessments described in paragraph (2).

(B)
Certain molecularly targeted cancer indications

A person that submits, on or after the date that is 3 years after

August 18, 2017
, an original application for a new active ingredient under section 355 of this title or section 262 of title 42, shall submit with the application reports on the investigation described in paragraph (3) if the drug or biological product that is the subject of the application is—

(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

A brief documentation of the scientific data supporting the conclusion under clauses (i) and (ii) shall be included in any pertinent reviews for the application under section 355 of this title or section 262 of title 42.

(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).
