The Company’s lead product candidate, TSC, is being developed to enhance the diffusion of oxygen to tissues with low oxygen levels, also known as hypoxia, a serious complication of many of medicine’s most intractable and difficult-to-treat conditions, including hypoxic tumors.

On April 18, 2022, the Company effected a 1-for-50 reverse split of its common stock. Any references in the unaudited condensed consolidated financial statements and related notes to share or per share amounts give retroactive effect to this reverse stock split.
