Bio Roundup: Seres Soars, MesoBlast Vote, Duchenne Decision & More

Xconomy National — 

The road of drug development is rife with detours and disappointments but Seres Therapeutics showed this week that course corrections can work. Four years after its microbiome therapy failed in a mid-stage study, the company reported early positive data from a pivotal test of its treatment for a type of gut infection.

The results are vindication for Cambridge, MA-based Seres (NASDAQ: MCRB). They’re also validation for the emerging microbiome medicines field, which has added many companies since Seres’s high-profile setback but has yet to yield an FDA-approved product. Could the Seres capsule of bacterial spores become the first? Investors seem to like its chances. Seres’s stock price soared after the news was announced, and the company took the opportunity to sell more shares, raising more than $245 million.

Our weekly roundup includes news of three other microbiome companies that struck deals, FDA approvals for a pair of rare disease drugs, and a vote of confidence for an experimental stem cell therapy. Read on for those stories and more.
