Shares of Sweden-based Hansa Biopharma AB (NASDAQ:HNSA) jumped 32.7% to SEK53.90 (US$5.81) on July 2 as Sarepta Therapeutics Inc. became the first partner to license its lead asset, imlifidase, to enable gene therapies to treat muscular dystrophy patients harboring neutralizing antibodies to the adeno-associated virus (AAV) vectors the medicines employ.
In late June, when Pfizer Inc. unveiled the first phase Ib data, mixed safety signal and all, for its Duchenne muscular dystrophy (DMD) gene therapy, PF-06939926, investors in Sarepta Therapeutics Inc. as well as Solid Biosciences Inc. watched with particular interest. The latter firm seems none the worse for wear, though, raising $60 million in a private placement.
