Aetna Updates Clinical Policy to Include Exhaled Nitric Oxide Giving Over 22 Million Additional Lives Access to FeNO Testing

FeNO Testing Deemed “Medically Necessary” for Asthma Patients

MORRISVILLE, NC – Circassia Pharmaceuticals, Inc. (“Circassia” or “the Company”), a specialty pharmaceutical company focused on respiratory disease, is pleased to announce that Aetna, one of the largest health insurance companies in the United States, has updated its Exhaled Breath Tests Clinical Policy to include the measurement of exhaled nitric oxide as “medically necessary” for the evaluation of asthma and for monitoring the response to long-term control therapy.

Circassia’s innovative NIOX® technology provides objective and accurate fractional exhaled nitric oxide (FeNO) measurement of airway inflammation at the clinical point of care. NIOX® is based on the discovery that patients with allergic/eosinophilic airway inflammation, the major underlying characteristic of asthma, generally have higher than normal levels of nitric oxide in their exhaled breath. By measuring the concentration of FeNO, NIOX® enables clinicians to evaluate airway inflammation in patients with underlying asthma, aiding diagnosis and helping guide treatment and reduce exacerbations. NIOX® is the only FeNO device for clinical use at the point of care available in the US.

David Acheson, Senior Vice President, US Commercial, said: “Aetna’s updated policy is excellent news for people with asthma and parents of children who live with asthma. The update includes data from a recent US Agency for Healthcare Research and Quality report that highlights the use of FeNO testing as a valuable part of comprehensive asthma diagnosis and management. We are pleased to see Aetna update its Clinical Policy Bulletin to include FeNO and provide expanded coverage to its members who have this serious condition.”

Aetna serves more than 22 million medical members and 1.2 million healthcare professionals. The Clinical Policy Bulletin expresses Aetna's determination of whether certain services or supplies are medically necessary, experimental and investigational, or cosmetic. Aetna reaches these conclusions based upon a review of currently available clinical information, including clinical outcome studies in the peer-reviewed published medical literature, regulatory status of the technology, evidence-based guidelines of public health and health research agencies, evidence-based guidelines and positions of leading national health professional organizations, views of physicians practicing in relevant clinical areas and other relevant factors.
