Capnia Enrolls First Patient in Phase 2 Clinical Trial Evaluating Nasal CO2 for the Symptomatic Treatment of Trigeminal Neuralgia

REDWOOD CITY, Calif., Feb. 25, 2016 (GLOBE NEWSWIRE) -- Capnia, Inc. (NASDAQ:CAPN), a diversified healthcare company that develops and commercializes innovative diagnostics, devices and therapeutics addressing unmet medical needs, today announced enrollment of the first patient in a Phase 2 clinical trial evaluating nasal, non-inhaled carbon dioxide nasal CO2 (nasal CO2) for the symptomatic treatment of trigeminal neuralgia (TN). In December 2015, the U.S. Food and Drug Administration (FDA) granted Orphan Drug Designation to the Company’s nasal CO2 technology for the treatment of TN.

The multi-center, placebo-controlled, single-blind clinical trial is designed to enroll up to 50 patients with TN. The primary efficacy endpoint of the trial is pain relief as reported on a visual analog scale (VAS) in a subject diary, assessed through 24 hours from initial dose. Jason Sheehan, M.D., Ph.D., Professor of Neurological Surgery and Neuroscience, University of Virginia Medical Center, is the principal investigator of the study. Capnia expects to report top-line data from this trial by the end of 2016.

“Trigeminal neuralgia is an extreme, sporadic, burning or shock-like facial pain that can last anywhere from a few seconds to many minutes per episode. If inadequately controlled, the pain associated with trigeminal neuralgia can be debilitating,” said Dr. Sheehan. “Many of the pharmaceutical alternatives for treating TN lose effectiveness over time, or they yield pain relief but with significant unpleasant side-effects. We are eager to evaluate Capnia’s nasal CO2 technology in a controlled setting as we pursue a new treatment paradigm for patients suffering from TN-related pain.”

“Enrollment of the first patient in this pilot clinical study is an important milestone for the therapeutic nasal CO2 development program for the treatment of TN,” said Anish Bhatnagar, M.D., Chief Executive Officer of Capnia. “We continue to execute on our strategy of bringing novel therapies based on our nasal CO2 technology to patients as quickly as possible.”

Capnia's therapeutic technology uses nasal, non-inhaled carbon dioxide, delivered at a low-flow rate into the nasal cavity to alleviate symptoms of allergies as well as pain disorders related to the trigeminal nerve. Capnia developed Serenz™ for the treatment of allergy symptoms, and has completed multiple clinical trials for the treatment of pain (such as migraine) using this technology. The use of Capnia's nasal CO2 product for the treatment of TN is supported by preclinical and clinical data demonstrating that CO2 may inhibit sensory nerve activation, may inhibit subsequent release of neuropeptides and may alleviate trigeminally-mediated pain. Collectively, these data suggest that nasal CO2 may provide relief of symptoms associated with TN.

About Trigeminal Neuralgia

Trigeminal neuralgia (TN) is a clinical condition characterized by debilitating pain in regions of the face innervated by one or more divisions of the trigeminal nerve. The pain is typically described as intense, sharp and stabbing, and is often described as one of the most painful conditions known to humans. It may develop without apparent cause or be a result of another diagnosed disorder, including multiple sclerosis and herpes zoster.

About Capnia

Capnia, Inc. is a diversified healthcare company that develops and commercializes innovative diagnostics, devices and therapeutics addressing unmet medical needs. Capnia's lead commercial product, CoSense, is based on the Sensalyze™ Technology Platform. It is a portable, non-invasive device that rapidly and accurately measures carbon monoxide (CO) in exhaled breath. CoSense has 510(k) clearance for sale in the U.S. and has received CE Mark certification for sale in the European Union. CoSense is used for the monitoring of CO from internal sources (such as hemolysis, a dangerous condition in which red blood cells degrade rapidly), as well as external sources (such as CO poisoning and smoke inhalation). The initial target market is newborns with jaundice that are at risk for hemolysis, comprising approximately three million births in the U.S. and European Union. The Company's commercial, neonatology-focused product line also includes innovative pulmonary resuscitation solutions, including the NeoPIP™ Infant T-Piece Resuscitator and Universal T-Piece Circuit consumables. Capnia's proprietary therapeutic technology uses nasal, non-inhaled CO2 and is being evaluated to treat the symptoms of allergies, as well as the trigeminally-mediated pain conditions such as cluster headache, trigeminal neuralgia and migraine.
