1. Nature of operations

Aquinox Pharmaceuticals, Inc. and its subsidiary, Aquinox Pharmaceuticals (Canada) Inc., (consolidated, the “Company”) is a pharmaceutical company discovering and developing novel therapeutics for conditions marked by inflammation, inflammatory pain, and blood cancers.

On June 27, 2018, the Company announced that its Phase 3 Leadership 301 clinical trial evaluating once-daily, oral rosiptor for the treatment of interstitial cystitis/bladder pain syndrome (IC/BPS) failed to meet its primary endpoint. As a result, all further development activities with rosiptor were halted. In July 2018, the Company announced a restructuring plan to reduce operating costs and better align the Company’s workforce with the needs of its business. On November 6, 2018, the Company’s Board of Directors approved further restructuring to reduce operating costs (see Note 11. Subsequent Event). The Company is currently evaluating strategic options.
