Shares of Galena Biopharma (NASDAQ:GALE) climbed Friday, after the biotechnology company said it received a notice of acceptance from the Australian Patent Office for a patent covering the use of its NeuVax vaccine candidate for inducing protective or therapeutic immunity to breast-cancer recurrence in patients with certain gene expressions.

The patent provides NeuVax the exclusivity for this indication until 2028, not including any patent term extensions, Galena said.
