The company led byMkel is now working to secure funding for clinical trials of TriSb92 in humans.. The active substance (azelastine hydrochloride) is a histamine-1 receptor antagonist, which shows anti-inflammatory effects via mast cell stabilization and inhibition of leukotriene and pro-inflammatory cytokine production2,3,4. 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. 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. It's a type of antibody that targets the coronavirus' spike protein. Google Scholar. If delivery took place within 24h after sampling, samples were to be stored at<25C, if storage period was greater than 24h (e.g., on Sundays), samples had to be stored and shipped at 28C. Smell retraining therapy (SRT) is a treatment for loss of smell, also referred to as hyposmia or anosmia. Odhar, H. A. et al.

Vitiello, A., Ferrara, F., Troiano, V. & La Porta, R. COVID-19 vaccines and decreased transmission of SARS-CoV-2. When treated with N-0385, 70% of the mice survived and had little to no lung damage. New research has answers, COVID's future: mini-waves rather than seasonal surges, Are repeat COVID infections dangerous? was the deputy investigator. Gottlieb, R. L. 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. Of note, 30 (non-related) adverse events in 13 patients (7 patients with 16 events in the 0.1% azelastine, 2 patients with 4 events in the 0.02% azelastine, and 4 patients with 10 events in the placebo group) were still ongoing at the final safety follow up on day 60. Treatment kits were manufactured by URSAPHARM Arzneimittel GmbH, Saarbruecken, Germany, according to the randomization list (as sequentially numbered containers). [1] Nasal delivery of an IgM offers broad protection from SARS-CoV-2 variants. Pharmacol. This way, the virus moves on.. Wlfel, R. et al. and B.S. was responsible for data management activities. the best experience, we recommend you use a more up to date browser (or turn off compatibility mode in Absolute changes in viral copy numbers (log10 cp/ml) from baseline (day 1) over time based on the ORF 1a/b gene (Ct<25 analysis set). Interestingly, significantly greater decrease in viral load was shown on day 4 of treatment in patients with high viral burden (Ct<25) treated with 0.1% azelastine compared to placebo, indicating that azelastine treatment may be advantageous for this patient population, particularly at an early timepoint of infection. and JavaScript. The independent 25 variable was the nasal carriage of Bacillus species. One of these smaller antibodies is being developedfrom llamas for example; another comes fromexperiments with yeast to develop synthetic nanobodies; and in a third case, researchers isolated nanobodiesfrom llamas and from mice and showed they could neutralize the SARS-CoV-2 virus. By blocking that access, compounds that target TMPRSS2 have the potential to be effective against both current and future variants. Will there be a COVID winter wave? Our study results provide the first human data showing that azelastine hydrochloride nasal spray used in a 0.1% concentration may be effective in accelerating the reduction of virus load in the nasal cavity and improving symptoms reported by COVID-19 patients. Thus, eligibility criteria were designed carefully to investigate a clearly defined, homogeneous study population of low-risk patients with a narrow age range. Identification of 14 known drugs as inhibitors of the main protease of SARS-CoV-2. 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. Rev. Google Scholar. Infect. Data was analysed primarily exploratively; there was no formal testing of a given hypothesis. https://doi.org/10.1016/s2213-2600(20)30354-4 (2020). 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. 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. Decreases of viral load were also reflected in increases of negative PCR results over time. Pujadas, E. et al. Even in cases where the antiviral does not prevent coronavirus infection, the treatment could slow infection. Ninety SARS-CoV-2 positive patients were randomized into 3 groups receiving placebo, 0.02% or 0.1% azelastine nasal spray for 11days, during which viral loads were assessed by quantitative PCR. Shapira, T., Monreal, I. 15, 75297536. EudraCT number: 2020-005544-34. 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. The reduction of the symptom score from baseline to day 11 was 8.389.42 in the 0.02% azelastine group and 11.129.45 in the placebo group. Ghahremanpour, M. M. et al. and showed they could neutralize the SARS-CoV-2 virus. The RBD is where the coronavirus attaches to cells in the body. Trial registration: The study was registered in the German Clinical Trial Register (DRKS-ID: DRKS00024520; Date of Registration in DRKS: 12/02/2021). The spritz developed by Moscona's team is one of a raft of proposed nasal sprays to prevent SARS-CoV-2 infection. At the end of the study, patients and investigators assessed the overall tolerability and efficacy of the treatment as very good (3), good (2), moderate (1) or poor (0). and JavaScript. https://doi.org/10.1056/NEJMc2027040 (2021). 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. CAS Duration of culturable SARS-CoV-2 in hospitalized patients with covid-19. 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.

The study was termed CARVIN (referring to COVID-19: Azelastine nasal spray Reduces Virus-load In Nasal swabs). 147, 400401. Within the subgroup of patients with baseline Ct values below 25, a similar progression of viral load data was observed (Fig. Of note, we cannot rule out the possibility that the placebo (nasal spray buffer) contributed to viral clearance. Med. Ther. The availability of a self-administrable nasal spray reducing subsequent viral transmission would have great impacts for the community as correlations between SARS-CoV-2 viral load and infectiousness have been shown23. Patients of the current trial were eligible upon positive PCR test results, and if enrolled no later than 48h after swab sampling. 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. June 16, 2022, U.S. Department of Health and Human Services, The researchers first tried one dose a day for seven days, starting a day before SARS-CoV-2 infection.
