Savara gets FDA break­through sta­tus de­spite large, late-stage fail­ure

Savara watched their stock crater in June as they an­nounced a late-stage fail­ure on their lead com­pound. But now, based on the same Phase III tri­al, the FDA is giv­ing the biotech and its rare lung dis­ease drug break­through ther­a­py des­ig­na­tion.

The des­ig­na­tion comes for Mol­gradex, an in­halant meant to treat au­toim­mune pul­monary alve­o­lar pro­teinosis (aPAP). It was the lead com­pound in Savara’s 2016 buy­out of Seren­dex. The dis­ease is caused by au­toan­ti­bod­ies that neu­tral­ize a pro­tein called GM-CSF in the lungs, and the in­halant re­plen­ish­es the lungs with a re­com­bi­nant form of the pro­tein.
