Sponsor's own description
This is a prospective, randomized placebo-controlled double blinded clinical trial in frontline healthcare workers managing COVID-19 patients. Participants will be weekly tested for SARS-CoV-2 and a panel of respiratory viruses. Treatment will be 3times a day for 84 days one puff into each nostirl and 3 puffs into mouth. Daily a symptom score will be recorded. The primary objective of the trial is to demonstrate that prophylactic treatment of health care workers managing COVID-19 patients with iota-carrageenan reduces symptoms of SARS-CoV-2 infections as well as infections with other respiratory viruses when compared to a placebo-treated control group.
