VANCOUVER, Canada I May 4, 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, today announced that it has reached its target enrollment in the Phase 2 KINSHIP trial of AQX-1125 for the treatment of atopic dermatitis.

“We are pleased with how enrollment has proceeded in this Phase 2 clinical trial,” said David Main, President and CEO of Aquinox. “Our non-clinical studies have led us to a potential link between skin inflammation and SHIP1 and we believe that the mechanism of action and properties of AQX-1125, as a once daily, oral, anti-inflammatory treatment, may provide a benefit to patients with atopic dermatitis.”

The KINSHIP clinical trial is being conducted at investigative sites in Canada as a randomized, double-blind, multicenter, placebo-controlled Phase 2 trial evaluating the efficacy and safety of AQX-1125 in approximately 50 adult patients with mild to moderate atopic dermatitis as a proof-of-concept trial in this indication. The KINSHIP trial’s primary endpoint is change from baseline in Total Lesion Symptom Score after 12 weeks of treatment. Secondary endpoints include safety, pharmacokinetics and additional efficacy endpoints, including the analyses of biopsies. Top line data from the KINSHIP trial is anticipated by the first quarter of 2016.

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 exploring AQX-1125 as an oral, once daily treatment in several Phase 2 trials.

About Atopic Dermatitis

Atopic dermatitis is a non-contagious disease characterized by chronically inflamed skin and sometimes intolerable itching. Atopic dermatitis may manifest as redness, scaling, and loss of the surface of the skin and is the most common of the many types of eczema, frequently associated with other allergic disorders, especially asthma and hay fever. While the etiology of atopic dermatitis remains largely unknown, the disease has been traced to a defect of the immune system within the skin. Considered to be underdiagnosed by physicians, the prevalence of atopic dermatitis ranges from 1%-20% worldwide. Atopic dermatitis affects an estimated 17.8 million Americans, with two-thirds of those suffering from the moderate to severe form of the disease where existing therapies are often inadequate, ineffective or unsuitable for long-term treatment.

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.
