SUPPLEMENTARY INFORMATION:

I. Background

FDA is announcing the availability of a guidance for industry entitled “Chronic Rhinosinusitis With Nasal Polyps: Developing Drugs for Treatment.” The guidance provides recommendations for sponsors developing products for the treatment of CRSwNP. Specifically, this guidance represents FDA's current thinking regarding trial population and design, effectiveness, statistical analysis, and safety for drugs being developed for the treatment of CRSwNP. This guidance does not address the clinical development of drugs for the treatment of chronic rhinosinusitis without nasal polyps or allergic fungal rhinosinusitis.

This guidance finalizes the draft guidance of the same title issued on December 10, 2021 (86 FR 70505). FDA considered comments received on the draft guidance in this finalized guidance. Chronic rhinosinusitis is characterized by inflammation of the nasal mucosa and paranasal sinuses and can be further divided into chronic rhinosinusitis with and without nasal polyps. Nasal polyps are inflammatory hyperplastic growths that protrude into the nasal passages. Symptoms of CRSwNP include nasal congestion, nasal discharge, facial pain or pressure, and loss of smell. Nasal polyps have associated morbidity that can have substantial impact on day-to-day functioning. Because of differences in natural history and treatment between chronic rhinosinusitis with and without nasal polyps, this guidance specifically addresses aspects of trial design, safety and efficacy assessment for CRSwNP. Changes from the draft to the final guidance include considerations for efficacy assessments for CRSwNP.

This guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The guidance represents the current thinking of FDA on “Chronic Rhinosinusitis With Nasal Polyps: 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 contained in 21 CFR part 312 relating to investigational new drug applications have been approved under OMB control number 0910–0014. The collections of information in 21 CFR part 314 relating to new drug applications have been approved under OMB control number 0910–0001. The collections of information contained in 21 CFR part 601 relating to biologics license applications have been approved under OMB control number 0910–0338.
