GeneOne Life Science Announces US FDA Approval of a Phase 2 Study of GLS-1200 Nasal Spray for COVID-19 Prevention

GeneOne Life Science receives FDA approval for a Phase 2 study of its nasal spray, GLS-1200, for COVID-19 prevention

GeneOne Life Science, Inc. announces today an Investigational New Drug (IND) approval by the U.S. Food and Drug Administration of a Phase 2 study of GLS-1200, its nasal spray for the prevention of COVID-19 infection. This study will recruit hospital personnel and other frontline healthcare workers who are at significantly higher risk for infection with COVID-19. In this study, GLS-1200 will be topically self-administered as a spray to the nose, the primary entry point for COVID-19 infection. GLS-1200 acts to stimulate nasal cells to produce nitric oxide (NO). NO has been shown to inhibit SARS coronavirus growth and infectivity. This study of GLS-1200 will enroll a total of 225 participants into a randomized, double-blind, placebo-controlled clinical trial. The study will investigate whether three-times daily nasal administration of GLS-1200 over 4 weeks can prevent infection with COVID-19 while in use.

Dr. Joel N. Maslow, Chief Medical Officer of GeneOne, states that “having a prophylactic treatment like GLS-1200 that is easily scalable and nasally administered to the point of entry of the virus can provide significant benefit.”

Mr. Young K. Park, CEO of GeneOne, states that “we have moved quickly to enable GeneOne to supply millions of doses, as we anticipate the Phase 2 study of GLS-1200 will demonstrate effectiveness in preventing infection.”
