Mesoblast Limited MESO recently announced that the FDA has granted a Rare Pediatric Disease (RPD) designation to its allogeneic cell therapy, Revascor (rexlemestrocel-L), for treating children with congenital heart disease. Shares of the company were up 20.9% in after-hours trading on Jan 18, following the announcement of the news.

The RPD designation is granted by the FDA to medicines that treat serious or life-threatening diseases, which usually affect children of all ages. Upon potential approval for Revascor by the FDA, the company may become eligible to receive a priority review voucher (“PRV”). This PRV can be used either by MESO in a subsequent marketing application filed with the FDA for a different product or may even be sold to any other third party to boost cash reserves.

The FDA granted the RPD tag to Revascor after the company submitted data from a randomized controlled study. The study investigated Revascor in children with hypoplastic left heart syndrome (HLHS), a potentially life-threatening congenital heart condition. The study was conducted on 19 children with HLHS.

Shares of Mesoblast have plunged 73.5% in the past year compared with the industry’s decline of 13.8%. Zacks Investment Research

Data from the study showed that a single intramyocardial administration of Revascor improved surgical outcomes and led to a significantly larger increase in left ventricular (LV) end-systolic and end-diastolic volumes in children with HLHS over a period of 12 months versus controls.

In November 2023, MESO submitted regulatory filings to the FDA seeking an orphan drug designation and rare pediatric disease designation for Revascor for the treatment of congenital heart disease HLHS.

Revascor is currently not approved in the United States. The company is also developing rexlemestrocel-L for treating chronic low back pain.
