If a regulatory agency discovers previously unknown problems with a product, such as adverse events of unanticipated severity or frequency, or problems with the facility where the product is manufactured, or disagrees with the promotion, marketing, or labeling of a product, such regulatory agency may impose restrictions on that product or us, including requiring withdrawal of the product from the market. If we fail to comply with applicable regulatory requirements, a regulatory agency or enforcement authority may, among other things, issue warning letters, impose penalties, suspend regulatory approvals, or require a product recall. Any of these actions by a regulatory agency could require us to expend significant time and resources, generate negative publicity, and adversely affect the value of our company.

To the extent we seek orphan drug designation for any of our product candidates, we may be unable to obtain such designations or to maintain the benefits associated with orphan drug status, including market exclusivity, which may cause our revenue, if any, to be reduced.

Under the Orphan Drug Act, the FDA may grant orphan designation to a drug or biologic intended to treat a rare disease or condition where there is no reasonable expectation that the cost of developing and making available the drug or biologic in the United States will be recovered from sales in the United States for that drug or biologic. Once granted, orphan drug designation entitles a party to financial incentives and certain exclusivity protections. In February 2019, the FDA granted orphan drug designation for our DNL310 program in Hunter syndrome. However, the FDA can still approve other drugs that have a different active ingredient for use in treating the same indication or disease, and can waive orphan exclusivity if we are unable to manufacture sufficient supply of our product. We plan to seek orphan drug designations for some other product candidates, but we may be unable to obtain such designations.

Further, in response to Catalyst Pharms., Inc. v. Becerra, 14 F.4th 1299 (11th Cir. 2021), the FDA clarified in a January 2023 notice that the FDA intends to continue to apply its longstanding interpretation of the regulations to matters outside of the scope of the Catalyst order – that is, the agency will continue tying the scope of orphan-drug exclusivity to the uses or indications for which a drug is approved, which permits other sponsors to obtain approval of a drug for new uses or indications within the same orphan designated disease or condition that have not yet been approved.
