SUPPLEMENTARY INFORMATION:

I. Background

FDA is announcing the availability of a draft guidance for industry entitled “Pulmonary Tuberculosis: Developing Drugs for Treatment.” The purpose of this draft guidance is to assist sponsors in the clinical development of investigational drugs for the treatment of pulmonary TB. Specifically, this draft guidance provides FDA's current recommendations regarding the overall development program and clinical trial designs for a new investigational drug or drugs to be used in combination with approved drugs or a new treatment regimen that includes one or more investigational drugs to support an indication for the treatment of pulmonary TB.

This draft guidance will revise and replace the draft guidance for industry of the same name issued November 6, 2013 (78 FR 66744). Since the 2013 final guidance was issued, there have been improvements in nonclinical models and further interest in streamlined clinical development programs as well as consideration for combination regimens with treatment-shortening regimens with improved safety and efficacy. Thus, in this revised draft guidance more detail is provided for nonclinical models, early phase studies and trial design considerations, including the demonstration of efficacy using superiority or noninferiority (NI) trial designs. Additionally, updates are made to pediatric patients being included in trials, endpoint and safety considerations, and labeling. The Appendix is also updated with an example of an NI margin justification.

This draft guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The draft guidance, when finalized, will represent the current thinking of FDA on “Pulmonary Tuberculosis: Developing Drugs for Treatment.” It does not establish any rights for any person and is not binding on FDA or the public. You can use an alternative approach if it satisfies the requirements of the applicable statutes and regulations.

II. Paperwork Reduction Act of 1995

While this guidance contains no collection of information, it does refer to previously approved FDA collections of information. Therefore, clearance by the Office of Management and Budget (OMB) under the Paperwork Reduction Act of 1995 (PRA) (44 U.S.C. 3501-3521) is not required for this guidance. The previously approved collections of information are subject to review by OMB under the PRA. The collections of information in 21 CFR part 312 have been approved under OMB control numbers 0910-0014. The collections of information in 21 CFR part 314 have been approved under OMB control number 0910-0001. The collections of information in 21 CFR part 601 have been approved under OMB control number 0910-0338. The collections of information in 21 CFR 201.56 and 201.57 have been approved under OMB control number 0910-0572.
