How is orphan drug exclusivity affected when the FDA-approved use for an orphan drug is arguably narrower than the treatment of the rare disease it was designated for?

By way of background, a sponsor can obtain orphan drug exclusivity when the FDA approves an application for a drug that has first been designated under 21 U.S.C. § 360bb of the Orphan Drug Act (ODA) for a “rare disease or condition.”  Id. § 360cc(a).  Except in any of three statutorily prescribed circumstances (§§ 360cc(b), (c)), the FDA cannot approve another application for the “same drug” for “the same disease or condition” for seven years after the first approval.

As we mentioned in the early days of the pandemic, COVID-19 has been accompanied by a rise in cyberattacks worldwide. At the same time, the global response to the pandemic has accelerated interest in the collection, analysis, and sharing of data – specifically, patient data – to address urgent issues, such as population management in hospitals, diagnoses and detection of medical conditions, and vaccine development, all through the use of artificial intelligence (AI) and machine learning. Typically, AIML churns through huge amounts of real world data to deliver useful results. This collection and use of that data, however, gives rise to legal and practical challenges. Numerous and increasingly strict regulations protect the personal information needed to feed AI solutions. The response has been to anonymize patient health data in time consuming and expensive processes (HIPAA alone requires the removal of 18 types of identifying information). But anonymization is not foolproof and, after stripping data of personally identifiable information, the remaining data may be of limited utility. This is where synthetic data comes in.
