What: Shares ofGalena Biopharmaclimbed by over 12% on exceptional volume today after the company announced the publication of two abstracts for the upcoming American Society of Clinical Oncology, or ASCO, meeting being held May 29 through June 2..

The main impetus behind today's move, though, appears to be the release of some intriguing early efficacy data for the folate protein binding vaccine, GALE-301, in terms of its ability to preventovarian and endometrial cancer recurrence in the adjuvant setting. Specifically, the company stated that patients receiving the 1000 mcg dose exhibited a 78% reduction in the relative risk of recurrence. The vaccine was also well tolerated across all doses, according to the press release.

So what: Galena is unquestionably a struggling biopharma that desperately needs good news on the clinical front. Earlier this year, the Food and Drug Administration issued a warning letter to Galena for not reporting 19 adverse events arising from patients taking its sublingual tablet Abstral for breakthrough cancer pain. And the company is only now emerging from its alleged stock promotion scandal last year that led to the ousting of CEO Mark Ahn.
