BATON ROUGE, La. – Researchers at Baton Rouge General are studying whether a new at-home nasal spray can prevent COVID-19. As part of the Phase 2 clinical trial, rhinologist Dr. Henry Barham and his team are looking for participants between the ages of 18 and 65 years old who have not had COVID-19.

“The initial data is very encouraging, and through this trial, we hope to find that a safe, effective prevention option that acts as a barrier of defense against upper respiratory infections like COVID-19,” said Dr. Barham.

While the COVID-19 vaccines stimulate adaptive or “memory” immunity by causing antibodies, the nasal spray studies innate immunity, which acts as the defense system a person is born with and serves as the first line of defense in preventing infection.

If a person meets the criteria and is eligible to participate in the study, it will involve using the self-administered nasal spray as well as four study-related office visits over the course of six weeks. For information on the study, call (225) 819-1181 or click here.
