Patient Treatment Act of 2013''.

SEC. 2. APPROVAL OF CERTAIN DRUGS FOR USE IN A LIMITED POPULATION OF 
              PATIENTS.

    (a) Approval of Certain Antibacterial and Antifungal Drugs.--
Section 505 of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 355) 
is amended by adding at the end the following:
    ``(x) Approval of Certain Antibacterial and Antifungal Drugs for 
Use in a Limited Population of Patients.--
            ``(1) Approval.--At the request of the sponsor of an 
        antibacterial or antifungal drug that is intended to treat a 
        serious or life-threatening disease or condition, the 
        Secretary--
                    ``(A) may approve the drug under subsection (c) to 
                treat a limited population of patients for which there 
                is an unmet medical need;
                    ``(B) in determining whether to grant such approval 
                for a limited population of patients, may rely on 
                traditional endpoints, alternative endpoints, or a 
                combination of traditional and alternative endpoints; 
                datasets of limited size; pharmacologic or 
                pathophysiologic data; data from phase 2 clinical 
                studies; and such other confirmatory evidence as the 
                Secretary deems necessary; and
                    ``(C) shall require the labeling of drugs approved 
                pursuant to this subsection to prominently include in 
                the prescribing information required by section 201.57 
                of title 21, Code of Federal Regulations (or any 
                successor regulation) the following statement: `This 
                drug is indicated for use in a limited and specific 
                population of patients.'.
            ``(2) Promotional materials.--The provisions of section 
        506(c)(2)(B) shall apply with respect to approval under this 
        subsection to the same extent and in the same manner as such 
        provisions apply with respect to accelerated approval under 
        section 506(c)(1).
            ``(3) Withdrawal of limited population approval 
        requirements.--If a drug is approved pursuant to this 
        subsection to treat a limited population of patients and is 
        subsequently approved or licensed under this section or section 
        351 of the Public Health Service Act, respectively, without 
        such a limitation, the Secretary may remove any labeling 
        requirements or postmarketing conditions made applicable to the 
        drug during the earlier approval process.
            ``(4) Relation to other provisions.--Nothing in this 
        subsection shall be construed to prohibit designation and 
        expedited review of a drug as a breakthrough therapy under 
        section 506(a), designation and treatment of a drug as a fast 
        track product under section 506(b), or accelerated approval of 
        the drug under section 506(c), in combination with approval of 
        the drug for use in a limited population of patients under this 
        subsection.
            ``(5) Rule of construction.--Nothing in this subsection 
        shall be construed to alter the standards of evidence under 
        subsection (c) or (d) (including the substantial evidence 
        standard in subsection (d)). Subsections (c) and (d) and such 
        standards of evidence apply to the review and approval of drugs 
        under this subsection, including whether a drug is safe and 
        effective. Nothing in this subsection shall be construed to 
        limit the authority of the Secretary to approve products 
        pursuant to this Act and the Public Health Service Act as 
        authorized prior to the date of enactment of this subsection.
            ``(6) Effective immediately.--The Secretary shall have the 
        authorities vested in the Secretary by this subsection 
        beginning on the date of enactment of this subsection, 
        irrespective of when and whether the Secretary promulgates 
        final regulations to carry out this subsection.''.
    (b) Licensure of Certain Biological Products.--Section 351(j) of 
the Public Health Service Act (42 U.S.C. 262(j)) is amended--
            (1) by striking ``(j)'' and inserting ``(j)(1)'';
            (2) by inserting ``505(x),'' after ``505(p),''; and
            (3) by adding at the end the following:
            ``(2) In applying section 505(x) of the Federal Food, Drug, 
        and Cosmetic Act to the licensure of biological products under 
        this section--
                    ``(A) references to an antibacterial or antifungal 
                drug that is intended to treat a serious or life-
                threatening disease or condition shall be construed to 
                refer to biological products intended to treat a 
                bacterial or fungal infection associated with a serious 
                or life-threatening disease; and
                    ``(B) references to approval of a drug under 
                section 505(c) of such Act shall be construed to refer 
                to licensure of a biological product under subsection 
                (a) of this section.''.
    (c) Monitoring.--Title III of the Public Health Service Act is 
amended by inserting after section 317T (42 U.S.C. 247b-22) the 
following:

            ``(1) the use of antibacterial and antifungal drugs, 
        including those receiving approval or licensure for a limited 
        population pursuant to section 505(x) of the Federal Food, 
        Drug, and Cosmetic Act; and
            ``(2) changes in bacterial and fungal resistance to drugs.
    ``(b) Public Availability of Data.--The Secretary, acting through 
the Director of the Centers for Disease Control and Prevention, shall 
make the data derived from monitoring under this section publicly 
available for the purposes of--
            ``(1) improving the monitoring of important trends in 
        antibacterial and antifungal resistance; and
            ``(2) ensuring appropriate stewardship of antibacterial and 
        antifungal drugs, including those receiving approval or 
        licensure for a limited population pursuant to section 505(x) 
        of the Federal Food, Drug, and Cosmetic Act.''.

SEC. 4. NO EFFECT ON HEALTH CARE PRACTICE.

    Nothing in the Antibiotic Development to Advance Patient Treatment 
Act of 2013 (including the amendments made thereby) shall be construed 
to restrict, in any manner, the prescribing of antibiotics or other 
products by health care professionals, or to limit the practice of 
health care.
Antibiotic Development to Advance Patient Treatment Act of 2013 - Amends the Federal Food, Drug, and Cosmetic Act (FFDCA) to authorize the Secretary of Health and Human Services (HHS) to approve the use of an antibacterial or antifungal drug that is intended for treatment of a serious or life-threatening disease or condition to treat a limited population of patients for which there is an unmet medical need. Requires the labeling of such drugs to prominently include in the prescribing information the statement that the drug is indicated for use in a limited and specific population of patients. Amends the Public Health Service Act to authorize the Secretary to license those antibacterial or antifungal drugs as biological products. Requires the Secretary, acting through the Director of the Centers for Disease Control and Prevention (CDC), to: (1) monitor the use of antibacterial and antifungal drugs, (2) monitor changes in bacterial and fungal resistance to drugs, and (3) make the information derived from such monitoring available to the public. Amends the FFDCA to direct the Secretary: (1) to identify upon approval, and subsequently update, susceptibility test interpretive criteria for antibacterial drugs by relying upon preclinical and clinical data, Bayesian and pharmacometric statistical methodologies, and such other confirmatory evidence the Secretary deems necessary; (2) on a quarterly basis, to evaluate new or updated criteria published by a nationally or internationally recognized standard development organization; and (3) to publish on the Food and Drug Administration's (FDA's) website a notice adopting, declining to adopt, or partially adopting such new or updated criteria.
