VANCOUVER, Canada I July 9, 2015 I Aquinox Pharmaceuticals, Inc. (“Aquinox“) (AQXP), a clinical-stage pharmaceutical company discovering and developing targeted therapeutics in disease areas of inflammation and immuno-oncology, announced today its Phase 2 FLAGSHIP clinical trial failed to demonstrate efficacy in chronic obstructive pulmonary disease (COPD) patients with a history of frequent exacerbations.

“We believe that FLAGSHIP was a robust and well conducted trial and the results are conclusive,” said David Main, President & CEO at Aquinox. “Given the encouraging activity seen in our recent LEADERSHIP trial our focus will be on the further development of AQX-1125 in bladder pain syndrome/interstitial cystitis. In addition, we are awaiting results from our KINSHIP trial in atopic dermatitis.”

In the FLAGSHIP trial, patients treated with 200 mg oral, once daily AQX-1125 for 12 weeks demonstrated no difference in COPD symptoms compared to placebo, as measured by EXACT, a patient-reported outcome tool. On the secondary endpoint of medically treated exacerbations there was also no benefit observed with AQX-1125.

Consistent with past results, the FLAGSHIP trial demonstrated AQX-1125 to be well tolerated. The overall adverse event rate was similar between AQX-1125 and placebo.

Aquinox will host a conference call and live audio webcast today July 9, 2015 at 9:00 AM (ET) / 6:00 AM (PT) to summarize and discuss these results in greater detail.

About the FLAGSHIP Trial

The FLAGSHIP trial was a multicenter, randomized (1:1), double-blind, placebo-controlled, Phase 2 clinical trial investigating the ability of 200mg, oral, once daily AQX-1125 to reduce the effects of exacerbations in 400 unstable patients with moderate to severe COPD. The primary endpoint was the change in the severity, duration and recurrence of COPD exacerbations in patients treated with AQX-1125 versus placebo, as measured by EXACT, a patient-reported outcome tool that measures symptoms. The FLAGSHIP trial was initiated in July of 2013 and enrolled subjects at investigative sites across Northern and Central Europe, Australia, New Zealand and the United States.

About the LEADERSHIP trial

The LEADERSHIP trial was a multicenter, randomized (1:1), double-blind, placebo-controlled, Phase 2 clinical trial investigating the ability of 200mg oral, once daily AQX-1125 to reduce pain in female patients with BPS/IC. The primary endpoint was to measure the difference in the change from baseline in the mean daily bladder pain score based on an 11-point numeric rating scale (NRS) at six weeks recorded by electronic diary. The trial was initiated in July of 2013 and conducted at investigative sites across Canada and the United States. A total of 69 subjects were enrolled. For more information on the LEADERSHIP trial, please see our recent press release announcing top line data June 25, 2015.

About AQX-1125

AQX-1125, Aquinox’s lead drug candidate, is a small molecule activator of SHIP1, which is a regulating component of the PI3K cellular signaling pathway. By increasing SHIP1 activity, AQX-1125 accelerates a natural mechanism that has evolved to maintain homeostasis of the immune system and reduce immune cell activation and migration to sites of inflammation. AQX-1125 has demonstrated preliminary safety and favorable drug properties in multiple preclinical studies and clinical trials. Aquinox is currently developing AQX-1125 as an oral, once daily treatment in bladder pain syndrome/interstitial cystitis. In addition, Aquinox is exploring AQX-1125 for atopic dermatitis in its ongoing KINSHIP Phase 2 trial with top line data expected by Q1 2016.
