Sec. 601.27  Pediatric studies.

    (a) Required assessment. Except as provided in paragraphs (b), (c), 
and (d) of this section, each application for a new active ingredient, 
new indication, new dosage form, new dosing regimen, or new route of 
administration shall contain data that are adequate to assess the safety 
and effectiveness of the product for the claimed indications in all 
relevant pediatric subpopulations, and to support dosing and 
administration for each pediatric subpopulation for which the product is 
safe and effective. Where the course of the disease and the effects of 
the product are similar in adults and pediatric patients, FDA may 
conclude that pediatric effectiveness can be extrapolated from adequate 
and well-controlled effectiveness studies in adults, usually 
supplemented with other information in pediatric patients, such as 
pharmacokinetic studies. In addition, studies may not be needed in each 
pediatric age group, if data from one age group can be extrapolated to 
another. Assessments required under this section for a product that 
represents a meaningful therapeutic benefit over existing treatments 
must be carried out using appropriate formulations for the age group(s) 
for which the assessment is required.
    (b) Deferred submission. (1) FDA may, on its own initiative or at 
the request of an applicant, defer submission of some or all assessments 
of safety and effectiveness described in paragraph (a) of this section 
until after licensing of the product for use in adults. Deferral may be 
granted if, among other reasons, the product is ready for approval in 
adults before studies in pediatric patients are complete, pediatric 
studies should be delayed until additional safety or effectiveness data 
have been collected. If an applicant requests deferred submission, the 
request must provide an adequate justification for delaying pediatric 
studies, a description of the planned or ongoing studies, and evidence 
that the studies are being or will be conducted with due diligence and 
at the earliest possible time.
    (2) If FDA determines that there is an adequate justification for 
temporarily delaying the submission of assessments of pediatric safety 
and effectiveness, the product may be licensed for use in adults subject 
to the requirement that the applicant submit the required assessments 
within a specified time.
    (c) Waivers--(1) General. FDA may grant a full or partial waiver of 
the requirements of paragraph (a) of this section on its own initiative 
or at the request of an applicant. A request for a waiver must provide 
an adequate justification.
    (2) Full waiver. An applicant may request a waiver of the 
requirements of paragraph (a) of this section if the applicant certifies 
that:
    (i) The product does not represent a meaningful therapeutic benefit 
over existing therapies for pediatric patients and is not likely to be 
used in a substantial number of pediatric patients;
    (ii) Necessary studies are impossible or highly impractical because, 
e.g., the number of such patients is so small or geographically 
dispersed; or
    (iii) There is evidence strongly suggesting that the product would 
be ineffective or unsafe in all pediatric age groups.
    (3) Partial waiver. An applicant may request a waiver of the 
requirements of paragraph (a) of this section with respect to a 
specified pediatric age group, if the applicant certifies that:
    (i) The product does not represent a meaningful therapeutic benefit 
over existing therapies for pediatric patients in that age group, and is 
not likely to be used in a substantial number of patients in that age 
group;
    (ii) Necessary studies are impossible or highly impractical because, 
e.g., the number of patients in that age group is so small or 
geographically dispersed;

    (iii) There is evidence strongly suggesting that the product would 
be ineffective or unsafe in that age group; or
    (iv) The applicant can demonstrate that reasonable attempts to 
produce a pediatric formulation necessary for that age group have 
failed.
    (4) FDA action on waiver. FDA shall grant a full or partial waiver, 
as appropriate, if the agency finds that there is a reasonable basis on 
which to conclude that one or more of the grounds for waiver specified 
in paragraphs (c)(2) or (c)(3) of this section have been met. If a 
waiver is granted on the ground that it is not possible to develop a 
pediatric formulation, the waiver will cover only those pediatric age 
groups requiring that formulation. If a waiver is granted because there 
is evidence that the product would be ineffective or unsafe in pediatric 
populations, this information will be included in the product's 
labeling.
    (5) Definition of ``meaningful therapeutic benefit''. For purposes 
of this section, a product will be considered to offer a meaningful 
therapeutic benefit over existing therapies if FDA estimates that:
    (i) If approved, the product would represent a significant 
improvement in the treatment, diagnosis, or prevention of a disease, 
compared to marketed products adequately labeled for that use in the 
relevant pediatric population. Examples of how improvement might be 
demonstrated include, e.g., evidence of increased effectiveness in 
treatment, prevention, or diagnosis of disease; elimination or 
substantial reduction of a treatment-limiting drug reaction; documented 
enhancement of compliance; or evidence of safety and effectiveness in a 
new subpopulation; or
    (ii) The product is in a class of products or for an indication for 
which there is a need for additional therapeutic options.
    (d) Exemption for orphan drugs. This section does not apply to any 
product for an indication or indications for which orphan designation 
has been granted under part 316, subpart C, of this chapter.
