ITTintention to treat. The higher viral load value may be explained with the dominance of the alpha (B.1.1.7) SARS-CoV-2 variant during the enrolment phase (Spring 2021, Germany16), which is known to infect the human nasal mucosa more efficiently than the wild-type and has been associated with higher viral load13,14. Future studies will help understanding the impact of azelastine hydrochloride in treating SARS-CoV-2 infected patients. Of those, 27 patients belonged to the 0.1% azelastine group, 28 patients to the 0.02% azelastine group and 26 patients to the placebo group (Fig. PubMed 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. Secondary endpoints included the assessment of symptoms, patient status (using a 11-category ordinal score as proposed by the WHO11), body temperature and blood oxygen saturation, quality of life (reported in the SF-36 generic quality of life questionnaires) and safety (adverse events, including worsening of patient status/symptoms) over time. Med. Science 371, 13791382 (2021). Now, researchers at Swansea University will test it against Covid-19 Now, researchers at Swansea University. In a subset of patients (initial Ct<25) viral load was strongly reduced on day 4 in the 0.1% group compared to placebo (p=0.005). ISSN 1476-4687 (online) This was a prospective, randomized, double-blind, placebo-controlled dose-finding proof-of-concept study, in which azelastine nasal spray was used in 2 doses: the commercially available concentration of 0.1% and a fivefold lower concentration of 0.02%. Absolute changes of total symptom scores from baseline (day 1) until day 11 of treatment (ITT analysis set). The improvement of the symptom shortness of breath was significantly greater on days 3 (p=0.004) and 4 (p=0.011) in the 0.1% azelastine group compared to placebo (supplementary Figure S3). Lee, C. & Corren, J. Symptoms were documented in patient diaries. Pharmacol. Various studies have looked at the role of different foods in preventing coronavirus infection severe Covid-19 These include seaweed and grapefruit-based nasal sprays, dark chocolate, tuna.

URSAPHARM Arzneimittel GmbH, Saarbruecken, Germany is the sponsor of the clinical trial. Inhibition of SARS-CoV-2 by bentonite-based nasal spray. Researchers began to work on compounds that stifle TMPRSS2s ability to interact with the viral protein. https://doi.org/10.1038/s41598-023-32546-z, DOI: https://doi.org/10.1038/s41598-023-32546-z. 13, 861295. https://doi.org/10.3389/fphar.2022.861295 (2022). It would be desirable to use a validated, COVID-19 specific questionnaire in future studies, and first attempts for its development are promising32. Google Scholar. Article Internet Explorer). 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. Researchers found that for people who regularly used a prescription corticosteroid like Beconase or Nasonex before getting sick with COVID-19, the risk of severe outcomes like hospitalization and death dropped by as much as 25%. https://cornellsun.com/2022/04/27/cornell-research-team-to-develop-covid-19-nose-spray-treatment/, Shapira, T., Monreal, I. Dings, C. et al. The current proof-of-concept study served to investigate if nasally applied azelastine may have the potential to reduce the viral load (via blocking viral entry and viral replication) in patients tested positively for SARS-CoV-2. KaplanMeier survival analyses with log-rank test were performed to display the occurrence of negative PCR test results upon treatment. As expected, a continuous decrease in the mean virus load was observed in all study groups during the 11 treatment days. Those compounds were tested in human lung and colon cells that were then exposed to SARS-CoV-2. B.R. and JavaScript. Data on virus variants was available for 59 patients and 54 (92%) of those carried the alpha (B.1.1.7) variant. While PCR results in the placebo group turned negative only on day 11 of treatment, individual patients of the 0.1% azelastine group already showed negative PCR test results from day 2 on. Overall, none of the participating patients had clinically relevant increased values of body temperature (data not shown). Viruses 12, 1384. https://doi.org/10.3390/v12121384 (2020). But the spike protein may mutate to evade immune response. contracts here. By Dr. Ramya Dwivedi, Ph.D. Jul 19 2021. Small differences were found with regard to age and bmi, which were both slightly higher in the azelastine 0.1% group (supplementary Table S1). From hydroxychloroquine and veterinarian doses of the antiparasitic drug ivermectin, questionableand potentially harmfultreatments for COVID-19 have circulated the internet. Michel, J. et al. Since the start of the COVID-19 pandemic, its treatment via the nasal route has been studied for a range of drugs17. Patients were assigned a treatment number in an ascending mode according to their chronological order of inclusion. The current study was a randomized, parallel, double-blind, placebo-controlled trial. The viral load reduction of the ORF 1a/b gene from baseline to day 11 was log10 5.042.05 in the 0.1% azelastine group, log10 4.391.74 in the 0.02% azelastine and log10 4.151.34 in the placebo group. Comirnaty is FDA-approved as a 2-dose series for the prevention of COVID-19 in individuals 12 years of age and older. The preventive application of a hydroxypropyl methyl cellulose nasal spray showed promising results in an observational survey, indicating that it may reduce SARS-CoV-2 infection rates19. For quantification of SARS-CoV-2-RNA in copies/mL, a standard curve derived from a dilution series of a SARS-CoV-2 cell culture isolate in VTM and adjusted to Ct values obtained from two samples with defined SARS-CoV-2-RNA copy numbers (106 and 105 copies/mL; INSTAND e.V., Duesseldorf, Germany) was used. Since azelastine has been shown to inhibit viral replication by 99.9% in Vero E6 cell culture and in reconstituted human nasal tissue cultures, it was assumed that a reduction of 3-log in virus load would be seen within 3days in actively treated patients, while no effect on virus load reduction would be seen in placebo treated patients. Importantly, this scenario corresponds to current COVID-19 treatment regimens (e.g., with monoclonal antibodies or antiviral substances), which are usually started at57days upon start of symptoms but are still efficacious. Comirnaty is also authorized . The company led byMkel is now working to secure funding for clinical trials of TriSb92 in humans.. SARS-CoV-2 infection progression starts with viral entrance mediated by the spike glycoproteins interaction with the host ACE2 receptor molecule. 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. Killingley, B. et al. New methods of fast-acting COVID-19 prevention are being researched to make it safer to be in large public gatherings like sporting events or concerts. The reduction of virus load (reflected by decreases of ORF 1a/b gene copy numbers) from baseline to the end of treatment (day 11) was log10 4.452.26 in the 0.1% azelastine group, log10 4.122.01 in the 0.02% azelastine and log10 3.821.61 in the placebo group (Fig. Only one of the 20 mice given saline survived.

Thus, a nitric oxide nasal spray was shown to reduce the viral load in adult patients with mild COVID-19 infection, and an accelerated SARS-CoV-2 clearance compared to placebo was demonstrated18. "CofixRX is an antiviral nasal spray that offers up to 8 hours of protection from many cold and flu viruses." [from your CofixRx Nasal Spray product label] "Lasts for up to 8 hours per. Further endpoints include infection. The hope is the vaccines will build immunity in one spot the coronavirus often invades . What scientists say. FH is the CEO of URSAPHARM Arzneimittel GmbH. The most promising compound, N-0385, virtually stopped infection in its tracks. Importantly, newly emerging virus variants have the potential to evade the immune response, thereby affecting the efficacy of specific therapies and underlining the importance of new treatment strategies. After treatment, virus load was reduced in all groups (p<0.0001) but was greater in the 0.1% group compared to placebo (p=0.007). Since the start of the Coronavirus Disease 2019 (COVID-19) pandemic, several independent research groups revealed azelastines potential as a promising candidate for drug repurposing to reduce SARS-CoV-2 viral load and infection rates5,6,7,8,9,10. Both descriptive and exploratory statistics were performed. Marc, A. et al. Acta Pharmacol. The researchers first tried one dose a day for seven days, starting a day before SARS-CoV-2 infection. Emerg. The spritz developed by Moscona's team is one of a raft of proposed nasal sprays to prevent SARS-CoV-2 infection. In an in vitro screening of 1,800 approved drugs by use of a SARS-CoV-2-S pseudovirus entry inhibitor model, 15 drugs were identified as active inhibitors, but only seven of these drugs were identified as active against SARS-CoV-2, three of which were anti-histamines: clemastine, trimeprazine and azelastine hydrochloride5.
