           Subpart C--Regulatory Review Period Determinations
 
Sec. 60.22  Regulatory review period determinations.

    In determining a product's regulatory review period, which consists 
of the sum of the lengths of a testing phase and an approval phase, FDA 
will review the information in each application using the following 
definitions of the testing phase and the approval phase for that class 
of products.
    (a) For human drugs:
    (1) The testing phase begins on the date an exemption under section 
505(i) of the Act becomes effective (or the date an exemption under 
former section 507(d) of the Act became effective) for the approved 
human drug product and ends on the date a marketing application under 
section 351 of the Public Health Service Act or section 505 of the act 
is initially submitted to FDA (or was initially submitted to FDA under 
former section 507 of the Act), and
    (2) The approval phase begins on the date a marketing application 
under section 351 of the Public Health Service Act or section 505(b) of 
the Act is initially submitted to FDA (or was initially submitted under 
former section 507 of the Act) and ends on the date the application is 
approved.
    (b) For food and color additives:
    (1) The testing phase begins on the date a major health or 
environmental effects test is begun and ends on the date a petition 
relying on the test and requesting the issuance of a regulation for use 
of the additive under section 409

[[Page 320]]

or 721 of the Act is initially submitted to FDA.
    (2) The approval phase begins on the date a petition requesting the 
issuance of a regulation for use of the additive under section 409 or 
721 of the Act is initially submitted to FDA and ends upon whichever of 
the following occurs last:
    (i) The regulation for the additive becomes effective; or
    (ii) Objections filed against the regulation that result in a stay 
of effectiveness are resolved and commercial marketing is permitted; or
    (iii) Proceedings resulting from objections to the regulation, after 
commercial marketing has been permitted and later stayed pending 
resolution of the proceedings, are finally resolved and commercial 
marketing is permitted.
    (c) For medical devices:
    (1) The testing phase begins on the date a clinical investigation on 
humans is begun and ends on the date an application for premarket 
approval of the device or a notice of completion of a product 
development protocol is initially submitted under section 515 of the 
Act. For purposes of this part, a clinical investigation is considered 
to begin on whichever of the following dates applies:
    (i) If an investigational device exemption (IDE) under section 
520(g) of the Act is required, the effective date of the exemption.
    (ii) If an IDE is not required, but institutional review board (IRB) 
approval under section 520(g)(3) of the Act is required, the IRB 
approval date.
    (iii) If neither an IDE nor IRB approval is required, the date on 
which the device is first used with human subjects as part of a clinical 
investigation to be filed with FDA to secure premarket approval of the 
device.
    (2) The approval phase either:
    (i) Begins on the date an application for premarket approval of the 
device is initially submitted under section 515 of the Act and ends on 
the date the application is approved; or
    (ii) Begins on the date a notice of completion of a product 
development protocol is initially submitted under section 515 of the Act 
and ends on the date the protocol is declared to be completed.
    (d) For animal drugs:
    (1) The testing phase begins on the date a major health or 
environmental effects test is begun or the date on which the agency 
acknowledges the filing of a notice of claimed investigational exemption 
for a new animal drug, whichever is earlier, and ends on the date a 
marketing application under section 512 of the Act is initially 
submitted to FDA.
    (2) The approval phase begins on the date a marketing application 
under section 512 of the Act is initially submitted to FDA and ends on 
the date the application is approved.
    (e) For purposes of this section, a ``major health or environmental 
effects test'' may be any test which:
    (1) Is reasonably related to the evaluation of the product's health 
or environmental effects, or both:
    (2) Produces data necessary for marketing approval; and
    (3) Is conducted over a period of no less than 6 months duration, 
excluding time required to analyze or evaluate test results.
    (f) For purposes of determining the regulatory review period for any 
product, a marketing application, a notice of completion of a product 
development protocol, or a petition is initially submitted on the date 
it contains sufficient information to allow FDA to commence review of 
the application. A marketing application, a notice of completion of a 
product development protocol, or a petition is approved on the date FDA 
sends the applicant a letter informing it of the approval or, by order 
declares a product development protocol to be completed, or, in the case 
of food and color additives, on the effective date of the final rule 
listing the additive for use as published in the Federal Register or, in 
the case of a new animal drug in a Category II Type A medicated article, 
on the date of publication in the Federal Register of the notice of 
approval pursuant to section 512(i) of the Act. For purposes of this 
section, the regulatory review period for an animal drug shall mean 
either the regulatory review period relating the drug's approval for use 
in

[[Page 321]]

nonfood-producing animals or the regulatory review period relating to 
the drug's approval for use in food-producing animals, whichever is 
applicable.
