LEADERSHIP Trial in BPS/IC and Reports Second Quarter 2015 Financial Results
VANCOUVER, British Columbia, Aug. 6, 2015 (GLOBE NEWSWIRE) — Aquinox Pharmaceuticals, Inc. (“Aquinox”) (NASDAQ:AQXP), a clinical-stage pharmaceutical company discovering and developing targeted therapeutics in disease areas of inflammation and immuno-oncology, today announced results from secondary endpoints from its Phase 2 LEADERSHIP trial with AQX-1125 in patients with bladder pain syndrome/interstitial cystitis (BPS/IC). Aquinox also provided a general business update and reported financial results for the second quarter ending June 30, 2015.

“Consistently positive results from multiple secondary endpoints have strengthened our confidence in further development of AQX-1125 for BPS/IC,” said Mr. David Main, President and CEO of Aquinox. “The encouraging effect of AQX-1125 observed on the primary endpoint of reduction in pain together with several statistically significant secondary endpoints, underscore the potential of AQX-1125 as a once daily, oral therapy for this debilitating disease.”

“We believe the next steps for AQX-1125 in BPS/IC include finalizing our pivotal trial designs in consultation with the appropriate regulatory authorities, including the FDA and EMA, to set a path to potential approval,” added Mr. Main.

Aquinox will host a conference call and live webcast on Thursday, August 6th, 2015 at 4:45 PM (ET) / 1:45 PM (PT) presenting additional results from the LEADERSHIP trial. Presentation slides will accompany the webcast and will be posted to the Aquinox website following completion of the call.

Business Highlights
Announced Encouraging Results from LEADERSHIP, a Phase 2 clinical trial of AQX-1125 in bladder pain syndrome/interstitial cystitis (BPS/IC). Aquinox reported top line results from its LEADERSHIP trial on June 25, 2015 did not reach statistical significance in its primary endpoint, but did demonstrate an encouraging trend in pain reduction for patients treated with AQX-1125 compared to placebo. The LEADERSHIP trial also demonstrated a high proportion of patients (49%) having achieved a clinically meaningful improvement in pain (2 points or greater on an 11-point NRS scale) as compared to placebo (39%).

Positive results from secondary endpoints, which included a statistically significant 1.3 point greater reduction over placebo on maximum daily pain at six weeks (p = 0.030) and a statistically significant 4.4 point greater reduction over placebo on the O’Leary Sant Symptom Scale at six weeks compared to placebo (p = 0.008), support further development of AQX-1125 in BPS/IC.
Approaching Top Line Data in KINSHIP, a Phase 2 clinical trial of AQX-1125 in atopic dermatitis. Target enrollment in the KINSHIP trial was achieved in early May 2015. Aquinox now anticipates top line data from the KINSHIP trial earlier than previously guided, now expected in Q4 2015. KINSHIP is designed to evaluate the safety and efficacy of AQX-1125 in approximately 50 mild to moderate atopic dermatitis patients.

Announced Top Line Results from FLAGSHIP, a Phase 2 clinical trial of AQX-1125 in chronic obstructive pulmonary disease (COPD) exacerbations. Top line results from the FLAGSHIP trial were reported on July 9, 2015, showing AQX-1125 provided no benefit to COPD patients with frequent exacerbations compared to placebo. Aquinox is currently not planning further development of AQX-1125 as a potential treatment for COPD.

Additional Development Activities. Aquinox is reallocating resources to high priority activities to support potential future registration and planned pivotal clinical trials with AQX-1125 in BPS/IC. Consequently, Aquinox is deferring the initiation of its Phase 2 trial in chronic rhinosinusitis with nasal polyps.

Summary of Financial Results
Cash Position. Cash, cash equivalents and investments totaled $29.0 million as of June 30, 2015, compared to $41.1 million as of December 31, 2014. This decrease was primarily driven by the advancement of AQX-1125 through the FLAGSHIP, LEADERSHIP and KINSHIP clinical trials. Aquinox expects its cash, cash equivalents and short-term investments to be sufficient to continue its operations and fund currently planned activities through the second quarter of 2016.

R&D Expenses. Research and development expenses for the second quarter of 2015 declined to $3.6 million from $4.6 million in the second quarter of 2014. The decline was the result of reduced expenditures as we approached the completion of the LEADERSHIP and FLAGSHIP trials.

G&A Expenses. General and administrative expenses of $1.2 million for the second quarter of 2015 were similar to the $1.1 million of general and administrative expenses for the second quarter 2014.
Net Loss. Net loss for the second quarter of 2015 was $4.8 million compared to a net loss of $5.4 million for the second quarter of 2014. This decline in net loss reflected the decrease in research and development expenses.

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 200 mg oral, once daily AQX-1125 to reduce pain in female patients with bladder pain syndrome/interstitial cystitis (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.

About Bladder Pain Syndrome/Interstitial Cystitis (BPS/IC)

BPS/IC is a chronic inflammatory bladder disease characterized by pelvic pain and increased urinary urgency and/or frequency. For many sufferers, these symptoms are severe and adversely affect all major aspects of their lives, including overall physical and emotional health, employment, social and intimate relationships, and leisure activities. While the cause of the disease remains largely unknown, erosion of the bladder lining is thought to be a significant contributor. BPS/IC is estimated to affect between 5 and 12 million people in the United States. Most BPS/IC patients continue to suffer this debilitating condition, despite treatment with existing therapies. Most current therapies and those in development are focused solely on symptomatic relief of BPS/IC. Aquinox believes new and innovative therapies that target the underlying disease in order to reduce the chronic pain and urinary symptoms are needed.

About the KINSHIP Trial
The KINSHIP trial is a multicenter, randomized, double-blind, placebo-controlled, Phase 2 clinical trial investigating the ability of AQX-1125 to reduce characteristic symptoms in approximately 50 patients with mild to moderate atopic dermatitis. The primary endpoint of the KINSHIP trial is change from baseline in Total Lesion Symptom Score after 12 weeks of treatment. The trial is being conducted at investigative sites across Canada.

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 in Q4 2015.
