AGENCY:

Food and Drug Administration, HHS.

ACTION:

Notice.

SUMMARY:

The Food and Drug Administration (FDA) is announcing the availability of a draft guidance for industry entitled “Community-Acquired Bacterial Pneumonia: Developing Drugs for Treatment.” The purpose of this draft guidance is to assist clinical trial sponsors and investigators in the development of antibacterial drugs for the treatment of community-acquired bacterial pneumonia (CABP). The science of clinical trial design and our understanding of this disease have advanced in recent years, and this draft guidance informs sponsors of our current recommendations for clinical development. FDA is specifically requesting comment on critical areas of scientific interest including the appropriate primary efficacy endpoints, the use of an intent-to-treat (ITT) population for the primary analysis population, and the use of antibacterial therapy by patients before participating in clinical trials. This draft guidance revises the draft guidance of the same name that published March 20, 2009.

DATES:

Although you can comment on any guidance at any time (see 21 CFR 10.115(g)(5)), to ensure that the Agency considers your comment on this draft guidance before it begins work on the final version of the guidance, submit either electronic or written comments on the draft guidance by April 10, 2014.

ADDRESSES:

Submit written requests for single copies of the draft guidance to the Division of Drug Information, Center for Drug Evaluation and Research, Food and Drug Administration, 10903 New Hampshire Ave., Bldg. 51, Rm. 2201, Silver Spring, MD 20993-0002. Send one self-addressed adhesive label to assist that office in processing your requests. See the SUPPLEMENTARY INFORMATION section for electronic access to the draft guidance document.

Submit electronic comments on the draft guidance to http://www.regulations.gov. Submit written comments to the Division of Dockets Management (HFA-305), Food and Drug Administration, 5630 Fishers Lane, Rm. 1061, Rockville, MD 20852.

I. Background

FDA is announcing the availability of a draft guidance for industry entitled “Community-Acquired Bacterial Pneumonia: Developing Drugs for Treatment.” The purpose of this draft guidance is to assist clinical trial sponsors and investigators in the development of antibacterial drugs for the treatment of CABP. Issues in CABP clinical trials were discussed at a 2008 workshop cosponsored by FDA and professional societies. Recently, there have been additional discussions about clinical trial design and endpoints for CABP at several meetings of the Anti-Infective Drugs Advisory Committee. As a result of these public discussions, the science of clinical trial design and our understanding of endpoints and approaches to clinical development have advanced.

This revised draft guidance supersedes the draft guidance published in March 2009 and informs sponsors of the changes in our recommendations. Although we acknowledge the challenges in conducting clinical trials of investigational antibacterial drugs in CABP, this revised draft guidance incorporates changes intended to attain a greater degree of balance between the practicability of conducting CABP clinical trials and the trial procedures needed for a scientifically sound and interpretable trial. We are specifically requesting input from the public on these changes for consideration before finalizing the guidance. Specifically, the changes from the 2009 draft guidance include:

  • A description of two potential primary efficacy endpoints for CABP clinical trials: (1) Improvement in patient symptoms early in the course of therapy for CABP (at day 3 to day 5) and (2) all-cause mortality.
  • A justification for a noninferiority margin based on clinical responses observed early in the course of therapy, as well as a justification for all-cause mortality as a primary efficacy endpoint.
  • Suggestions for efficacy analyses based on: (1) An overall ITT population and (2) a microbiological intent-to-treat population consisting of those patients who have a documented bacterial pathogen known to cause CABP.
  • An approach for accommodating enrollment of patients who have received prior antibacterial therapy, provided certain constraints are met.

Issuance of this guidance fulfills a portion of the requirements of Title VIII, section 804, of the Food and Drug Administration Safety and Innovation Act (Publ. L. 112-144), which requires FDA to “review and, as appropriate, revise not fewer than 3 guidance documents per year . . . for the conduct of clinical trials with respect to antibacterial and antifungal drugs. . . .”

This draft guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The draft guidance, when finalized, will represent the Agency's current thinking on this topic. It does not create or confer any rights for or on any person and does not operate to bind FDA or the public. An alternative approach may be used if such approach satisfies the requirements of the applicable statutes and regulations.

II. The Paperwork Reduction Act of 1995

This draft guidance refers to previously approved collections of information that are subject to review by the Office of Management and Budget (OMB) under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). The collections of information in 21 CFR part 312 have been approved under OMB control number 0910-0014 and the collections of information in 21 CFR part 314 have been approved under OMB control number 0910-0001.
