Researchers supported in part by the National Institute of Allergy and Infectious Diseases (NIAID) have developed a nasal spray that has the potential to not only treat COVID-19 but also prevent SARS-CoV-2 infection in a way that the virus cant mutate to avoid. Could a nose spray a day keep COVID away? - nature.com Dings, C. et al. identified azelastine as an anti-viral candidate and demonstrated pronounced anti-SARS-CoV-2 activity in vitro10. For male patients, the assessment was done via phone call. Multinomial regression analysis was done to 26 determine the association between nasal carriage of Bacillus and COVID-19 severity after 27 adjusting for age, sex, and co-morbidity status. 62, 50937, Cologne, Germany, Henning Gruell,Maike Schlotz&Florian Klein, Ursatec GmbH, Marpinger Weg 4, 66636, Tholey, Germany, ClinCompetence Cologne GmbH, Theodor-Heuss-Ring 14, 50668, Cologne, Germany, Belisa Russo,Susanne Mller-Scholtz,Cengizhan Acikel,Hacer Sahin,Nina Werkhuser,Silke Allekotte&Ralph Msges, Institute of Medical Statistics and Computational Biology (IMSB), Faculty of Medicine, University of Cologne, Kerpener Str. Evaluation of AUC values (reflecting baseline adjusted decreases of viral load over 11days) showed that the 0.1% azelastine group exhibited a greater AUC value of 24.1413.12 (referring to greater decrease) compared to the placebo group with an AUC value of 18.894.70 (p=0.007, Fig. One puff of the respective nasal spray was applied per nostril, 3 times a day (morning, midday, evening). Although it may be expected that the azelastine might be most efficacious during very early time points after infection, its application in the current study setting could only be started during the symptomatic phase of the disease. TriSb92 isone of multiple nasal spray approaches but unlikely to be as durable as effective nasal vaccines, saidEricTopol, MD, a professor of molecular medicine and executive vice president of Scripps Research in La Jolla, CA. Applied treatment regimens aimed to explore differences regarding viral carriage upon treatment with azelastine compared to placebo. Since viral levels during early infection with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) tend to be highest in the nose and nasopharynx1, a nasal spray with an active substance inhibiting virus entry and replication may stop or delay the progression of the disease to the lower respiratory system and reduce the transmission to uninfected individuals. Wiesmller (health authorities Cologne, Germany) for his support regarding regulatory issues, PD Dr. E. Raskopf for editorial assistance, and H. Papp for her assistance in PCR control experiments. Because N-0385 was suitable for use as a nasal spray, researchers used a mouse model that develops severe COVID-19 and gave the mice either N-0385 or control doses of saline in their noses. Even in cases where the antiviral does not prevent coronavirus infection, the treatment could slow infection. Pharmacol. Pediatr. Ralph Msges. J.

If all goes well, the hope is that we'll have a safe and effective nasal spray to serve as an extra line of defense in the fight against COVID-19. Expert. The RBD is where the coronavirus attaches to cells in the body. E.N., V.S., G.N., R.K., A.B., M.F. March 31, 2023 - An antiviral therapy in early development has the potential to prevent COVID-19 infections when given as a nasal spray as little as 4 hours before exposure. In addition, presence or absence of fever (38.0C) was documented daily (0=no fever, 3=fever). Patients were assigned a treatment number in an ascending mode according to their chronological order of inclusion. It's a type of antibody that targets the coronavirus' spike protein. Whether the current data can be extrapolated to other SARS-CoV-2 variants needs to be investigated. 76, 469475. Asthma inhalers: Which one's right for you? - Mayo Clinic The company led byMkel is now working to secure funding for clinical trials of TriSb92 in humans.. All this made her work personal: for the past decade, Moscona, a molecular virologist, had been hunting for compounds that could stop viruses in their tracks, before the pathogens infect even a single cell in a persons body. The hope is the vaccines will build immunity in one spot the coronavirus often invades . PubMed Central contracts here. Internet Explorer).

A minimal common outcome measure set for COVID-19 clinical research. Viral load and disease severity in COVID-19. This could happen by limiting how much virus could replicate early in the skin inside the nose and nasopharynx (the upper part of the throat), saidMkel, who is also CEO of Pandemblock Oy, the company set up to develop the product. In a highly relevant and translational in vitro model using reconstituted human nasal tissue, a fivefold diluted commercially available azelastine nasal spray solution inhibited viral replication almost completely within 72h after SARS-CoV-2 infection10. and B.S. 13, 861295. https://doi.org/10.3389/fphar.2022.861295 (2022). One study of about 400 health-care workers suggests a nasal spray may reduce the incidence of COVID-19 by up to 80 per cent. The primary endpoint of the CARVIN study was the assessment of virus load kinetics of SARS-CoV-2 by determining the presence and amount of viral carriage via PCR. Subgroups were analysed exploratorily (e.g., subgroups regarding gender, age, symptom severity, etc.). Winchester, S., John, S., Jabbar, K. & John, I. Unlike a COVID vaccine that boosts a persons immune system as protection, the antiviral nasal spray works more directly by blocking the virus, acting as a "biological mask in the nasal cavity," according to, One of these smaller antibodies is being developed, to develop synthetic nanobodies; and in a third case, researchers isolated nanobodies. Med. PubMed Central Scientists are working on fast-acting nasal sprays to block coronavirus infections but formulating the sprays is a challenge. During visits, nasopharyngeal swabs were taken for quantitative PCR measurements, and investigators assessed the patient status in accordance with the WHO clinical progression scale11. . The WHO clinical progression scale progressively decreased in all treatment groups during the study. Res. Data on virus variants was available for 59 patients and 54 (92%) of those carried the alpha (B.1.1.7) variant. Comparable numbers of adverse events occurred in all treatment groups with no safety concerns. Sci Rep 13, 6839 (2023). Importantly, the AUC analysis depicting the viral load decrease based on the detection of the ORF 1a/b gene over the 11-day treatment period showed a significantly greater reduction of virus load in the 0.1% azelastine group compared to placebo. the epithelium, to recreate the first line of defense against respiratory viruses.

Approval of the study by the German Federal Institute for Drugs and Medical Devices (BfArM) was given on 3rd February 2021. Article It was more effective against the virus, though, when given before infection rather than after, perhaps due to the initial establishment of the infection," the researchers note. All rights reserved. Identification of SARS-CoV-2 entry inhibitors among already approved drugs. PubMed KaplanMeier analysis results regarding the ORF 1a/b gene from baseline (day 1) until day 11 of treatment (ITT analysis set). The anti-histamine azelastine, identified by computational drug repurposing, inhibits infection by major variants of SARS-CoV-2 in cell cultures and reconstituted human nasal tissue. Azelastine hydrochloride nasal spray is an approved medicinal product currently available at a concentration of 0.1% w/v to treat allergic rhinitis. PubMed It also appears to work as a treatment if used within 4 hours after infection inside the nose, new research reveals., Known as TriSb92(brand name Covidin, from drugmaker Pandemblock Oy in Finland), the viral inhibitoralso appears effective against all coronavirus variants of concern, neutralizing even the Omicron variants BA.5, XBB, and BQ.1.1 in laboratory and mice studies., Unlike a COVID vaccine that boosts a persons immune system as protection, the antiviral nasal spray works more directly by blocking the virus, acting as a "biological mask in the nasal cavity," according to the biotechnology company set up to develop the treatment.. Google Scholar. Cornell research team to develop COVID-19 nose spray treatment. Thank you for visiting nature.com. The current study demonstrated a gradual decrease of patients symptoms and improvements of quality of life. The spritz developed by Moscona's team is one of a raft of proposed nasal sprays to prevent SARS-CoV-2 infection. Kim, M.-C. et al. The team will enrol 480 healthworkers, including nurses and doctors . Overall, no statistical differences between groups were determined. Head Neck Surg. The Coronavirus Immunotherapy Consortium identified new candidate drugs based on monoclonal antibodies in work funded by NIAID. Bearing in mind the low number of participants in the current proof-of-concept study, the results still build a promising foundation for a currently running phase III study, during which effects of azelastine nasal spray on symptom severity and progression to severe COVID-19 disease are investigated in a greater patient population. ADS was the principal investigator responsible for the conduct of the study, M.G. Moreover, this group showed that azelastine has the potential to inhibit SARS-CoV-2 cell entry by binding to the angiotensin-converting enzyme 2 (ACE2) receptor and to inhibit intracellular virus replication through binding to the sigma-1 receptor6. Smell retraining therapy (SRT) is a treatment for loss of smell, also referred to as hyposmia or anosmia. Early intervention with azelastine nasal spray may reduce viral load in Negative PCR results appeared earlier and more frequently in the azelastine treated groups: being 18.52% and 21.43% in the 0.1% and 0.02% groups, respectively, compared to 0% for placebo on day 8. However, examples of prolonged nasal positivity have also been reported, and many factors are known to have an influence on the individual viral load and clearance27. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. The study was termed CARVIN (referring to COVID-19: Azelastine nasal spray Reduces Virus-load In Nasal swabs). Pawar, R. D. et al. The investigators judged the efficacy as good or very good in 74.1% (0.1% azelastine treatment), 82.1% (0.02% azelastine treatment) and 73.1% (placebo treatment) of treated patients. In a study funded by NIAID, researchers are using mice to look for genes that account for different COVID-19 symptoms. PM, MF, DG, CS and BS are employed at URSAPHARM Arzneimittel GmbH. This trial was conducted at the Department of Otorhinolaryngology, Head and Neck Surgery of the Faculty of Medicine of the University of Cologne, Germany. This is exemplified by the emergence of the highly immune evasive omicron variant that is resistant to many monoclonal antibodies authorized for clinical use34.
