Dexmedetomidine (“Dex”)

Dex Has Demonstrated Analgesia & Safety Alpha 2 agonist (non-opioid) Injectable form (Precedex) marketed by Hospira in US as sedative Multiple studies demonstrating analgesia of alpha 2 agonists Intranasal formulation in clinical development for peri-procedural pain In-licensed non-IV rights from Orion Worldwide rights except Europe, Turkey, and CIS Multiple studies demonstrate Dex pain relief and safety profile Including our completed placebo controlled trials Expect strong IP position Pending IP coverage could run through 2030 Expect to file 505(b)(2) NDA after completion of Ph III

Positive Dex-IN Ph II Results (REC-14-013 – Post Op Day 1 Dosing) Randomized, placebo controlled Phase II bunionectomy study (168 patients) Randomized, placebo controlled study 50 mcg of Dex-IN or placebo every 6 hours Primary endpoint – SPID48 (p=0.0214) Oral opioid rescue therapy allowed 6 patients discontinued for lack of efficacy (3 in each treatment group) and 1 patient due to serious adverse event of hypotension Most common adverse events observed in the study were: blood pressure decrease / hypotension nausea (similar incidence to placebo) nasal discomfort and headache Adverse event of bradycardia was reported in 3 subjects in the Dex-IN treatment group
