Synopsis :
FabiSpray is a Nitric Oxide Nasal Spray (NONS) designed to kill the COVID-19 virus in the upper airways. It has proven anti-microbial properties with a direct virucidal effect on SARS-CoV-2.
Glenmark Pharmaceuticals Limited and Canadian pharmaceutical company SaNOtize Research & Development Corp. has launched FabiSpray in India for the treatment of adult patients with COVID-19 who have high risk of progression of the disease.

FabiSpray
NONS when sprayed over nasal mucosa acts as a physical and chemical barrier against the virus, preventing it from incubating and spreading to the lungs.
Glenmark has received manufacturing and marketing approval from the Drugs Controller General of India (DCGI) for NONS as part of the accelerated approval process.
A Phase 3 clinical trial was conducted in adult COVID-19 patients across 20 clinical sites in India. The double-blind, parallel arm, multicenter study, conducted in 306 patients evaluated the efficacy and safety of Nitric Oxide Nasal Spray versus normal saline nasal spray in non-hospitalized adult patients. All patients received standard supportive care in the study.
The trial analyzed patients with risk of progression of disease – non-vaccinated patients, patients in the middle and older age group and patients with co-morbidities. Primary endpoint was met: Reduction in log viral load in the NONS group was statistically significant and superior to the control (placebo) group (p < 0.05).
The median time to virological cure was 4 days in the NONS group and 8 days in the placebo group (p < 0.05). A significantly higher proportion of patients demonstrated a 2-point improvement on the WHO Progression Scale (a validated clinical endpoint) in the NONS group as compared to the placebo group (p < 0.05).
NONS was safe and well tolerated by patients. No patients experienced moderate, severe, serious Adverse Events (AE) or death in the study.
Dr. Monika Tandon, Senior VP & Head – Clinical Development, Glenmark Pharmaceuticals Ltd commented, “The results from this Phase 3, double blind, placebo controlled trial are encouraging. Demonstration of reduction in the viral load has significant positive impact from a patient and community perspective. In the current scenario, with new emerging variants exhibiting high transmissibility, NONS provides a useful option in India’s fight against COVID-19.”
In March 2021, clinical trials from its innovator, SaNOtize showed NONS was a safe and effective antiviral treatment of SARS CoV-2. In the first 24 hours, NONS reduced the average viral load by around 95%, and then by more than 99% within 72 hours. (In the India Phase 3 trial, a reduction of viral load of 94% in 24 hours and 99% in 48 hours was similar to reduction seen in the UK NHS trial conducted by SaNOtize).
NONS has been tested in healthy volunteers and patients as part of Canada and UK clinical trials. SaNOtize has an ongoing global Phase 3 prevention trial, which will further add to its efficacy. As per studies conducted in the Utah State University USA, NONS is proven to kill 99.9% of SARS-Cov-2 virus including Alpha, Beta, Gamma, Delta, and Epsilon variant within 2 minutes.
Dr. Srikanth Krishnamurthy one of the Principal Investigators of the study commented, “Nitric Oxide Nasal Spray lowers the viral load and hastens RT-PCR negativity when used early in COVID 19 infection leading to recovery. Most importantly, viral load reduction with NONS has the potential to reduce the chain of transmission. Last but not the least, NONS being topical, is safe, and makes this therapeutic option very attractive”.
Commenting on the significance of this development, Robert Crockart, Chief Commercial Officer, Glenmark Pharmaceuticals Ltd said, “We are happy to receive regulatory approval for Nitric Oxide Nasal Spray (FabiSpray) and launch it in partnership with SaNOtize. This reaffirms our commitment of providing yet another safe and effective antiviral treatment for COVID-19, and we are confident it will offer patients a much needed and timely therapy option.”
In July 2021, Glenmark entered into an exclusive long term strategic partnership with Canadian biotech firm SaNOtize, to manufacture, market and distribute its breakthrough Nitric Oxide Nasal Spray for COVID-19 treatment in India and other Asian markets including Singapore, Malaysia, Hong Kong, Taiwan, Nepal, Brunei, Cambodia, Laos, Myanmar, Sri Lanka, Timor-Leste and Vietnam.
NONS has already received a CE mark in Europe, which is an equivalent of marketing authorization in case of a Medical Device. By virtue of the CE mark, SaNOtize has permission to launch NONS in the EU.
NONS is also approved and being sold in Israel, Thailand, Indonesia and Bahrain, under the name enovid or VirX. NONS is approved in many counties for protection against viruses including SARS COV-2.
