Changes Sought in LPAD Draft Guidance
Pharmaceutical Research and Manufacturers of America says it generally supports the FDA proposed limited population pathway for antibacterial and antifungal drugs (LPAD) and provides comments on the draft guidance: need for revisions to accurately reflect statutory language; FDA LPAD pathway eligibility determinations made at a time of approval may discourage pathway use based on sponsor uncertainty; FDA should not inadvertently discourage development under the pathway of medicines to treat rare diseases.
The Biotechnology Innovation Organization says the draft guidance provides welcome clarity for sponsors developing antibiotic and antifungal drugs under the pathway created by the 21st Century Cures bill. It offers these comments: additional examples of products for which the LPAD approval pathway might be valuable or necessary would be helpful; additional clarification is needed to inform clinical trial design for LPAD products; FDA should consider how new initiatives to modernize drug development and review may be applied to LPAD products; additional guidance is requested on labeling; and clarity is needed on communication of promotional material.
