OGEN Oragenics Inc

Oragenics, Inc. (NYSE American: OGEN) (“the Company”), a company focused on developing unique, intranasal pharmaceuticals for the treatment of neurological disorders, today announced the completion of its spray-dried formulation and filling in the nasal device for its lead candidate, ONP-002, for concussion. ONP-002 is a new chemical entity (NCE) designed to target the brain through delivery into the nasal cavity. The prefilled formulation is intended to provide the needed drug-device dosing for the planned Phase IIa clinical trial in concussed patients.

For the trial, the Company produced both placebo and ONP-002 drug for use in the Phase IIa clinical trial to be conducted in Australia. The work included the production of ONP-002 as a spray-dried nanoparticle formulation, loading of the powder in Oragenics’ novel breath-propelled intranasal device, and initiating a stability program of both the drug formula alone and within the device. The Phase IIa clinical trial is expected to enroll 40 concussed patients who will receive 1:1 either placebo or the ONP-002 drug, with doses given twice a day for five consecutive days following injury. The trial aims to start treatment within 8 hours of the injury in the emergency department. It is anticipated that patient-reported outcomes and blood biomarkers will be included in the evaluation.

“In preparing for the Phase IIa study, we wanted to ensure that ONP-002 could be formulated as a nanoparticle and delivered intranasally as a powder to improve brain exposure. The anti-inflammatory effects of our novel neurosteroid are designed to reduce negative outcomes after a concussion. We believe the combination of the spray-dried powder in our device is ideal for field delivery, increasing the chances of stopping the neuropathology of a concussive injury early,” commented Michael Redmond, President for Oragenics.

About Concussion

Concussion is an unmet medical need. There are an estimated 69 million concussions annually reported worldwide. Common causes of concussion include falls, motor vehicle accidents, and contact sports. Other neurological disorders, including Alzheimer’s Disease, Parkinson’s Disease, and Chronic Traumatic Encephalopathy (CTE), have been linked to concussion. Post-concussion symptomology is linked to long-term disability and occurs in as high as 20% of concussed patients.
