Approval of the study by the German Federal Institute for Drugs and Medical Devices (BfArM) was given on 3rd February 2021. Detection of the alpha (B.1.1.7) variant was based on single nucleotide polymorphism analysis for SARS-CoV-2 spike gene mutation N501Y and deletion H69/V70. Zapor, M.

A Boots nasal spray for cold and flu has shown positive results during testing to see if it could help tackle coronavirus infections. Now, researchers at Swansea University will test it against Covid-19. At the end of the treatment, 48.2% of the patients of the 0.1% azelastine group showed no detection of the ORF 1a/b gene, whereas only 23.1% of patients of the placebo group showed negative PCR results (supplementary Table S4). Front. 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. At V1, a comparable distribution of patients with a score of 1 (14.8% in the 0.1% azelastine group, 14.3% in the 0.02% azelastine group and 23.1% in the placebo group) or 2 (85.2% in the 0.1% azelastine group, 85.7% in the 0.02% azelastine group and 76.9% in the placebo group) was observed. It would be desirable to use a validated, COVID-19 specific questionnaire in future studies, and first attempts for its development are promising32. 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. Short intervals of swab collection time points, particularly during early days of infection, and high number of PCR tests aimed to monitor SARS-CoV-2 viral loads as closely as possible, considering that only limited knowledge regarding details of viral clearance was publicly available at the time of the study development. Categorical data were described by absolute frequencies and percentage of valid cases. . Boots Dual Defence, which contains Carragelose, a patented version of iota-carrageenan, is already clinically proven to help shorten the duration and severity of cold and flu-like symptoms,[ii] and new in-vitro (test tube) laboratory study results suggest that Carragelose could also reduce the risk of an infection with SARS-CoV-2, the virus which The physical and mental health summary scores of the SF-36 questionnaire improved during the course of the treatment without statistical differences between groups (data not shown). Cegolon, 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. With the changing epidemiology of COVID-19 and its impact on our daily lives, there is still an unmet need of COVID-19 therapies treating early infections to prevent progression. HG, MS, and FK declare no conflict of interest. By application of a novel computational approach based on Shannon entropy homology, Konrat et al. 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. contributed to the study conceptualisation.

Article Additionally, safety follow-ups were performed at 2 time-points. The overall AUC of the Azelastine 0.1% group (red area) was significantly greater than that of placebo (green area), p=0.007. It's a type of antibody that targets the coronavirus' spike protein. 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. The current study demonstrated a gradual decrease of patients symptoms and improvements of quality of life.

Of note, we cannot rule out the possibility that the placebo (nasal spray buffer) contributed to viral clearance. PubMed The aim of our study was to support the preclinical evidence for azelastines antiviral activity in patients tested positive for SARS-CoV-2.

BR, SMS, HS, CA, NW, SA, and RM are employees of ClinCompetence Cologne, the CRO which organized this trial. It would be desirable to study azelastine treatment in a greater COVID-19 population to get further insights on azelastines effects on individual symptoms and to determine its potential on long-term symptoms. Struct. 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. Z.

ADS 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. 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. Whether the current data can be extrapolated to other SARS-CoV-2 variants needs to be investigated. Emerg. Pujadas, E. et al. Loading Twitter content.

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.

The dual-target RT-PCR independently targets the ORF1a/b and the sarbecovirus E genes, and assays were considered positive if at least one target returned a positive result (Ct values reflecting an inverse relationship with viral load). The first administration of the nasal spray was carried out in the presence of the investigator; products were subsequently self-administered for 11days (treatment phase).

It should be noted that the SARS-CoV-2 alpha variant (B.1.1.7) was the dominant variant in Germany during the enrolment phase of the current study16. The sample size calculation was based on the expected reduction of virus load during the treatment considering 3 treatment arms. Postdoctoral Fellow Scholarship at Dept of Biochemistry of Vanderbilt University. the epithelium, to recreate the first line of defense against respiratory viruses. 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. N. Engl. Pharmacol. The reduction in the symptom score was clinically relevant for all three groups. In a study examining the effect of azelastine nasal spray on upper respiratory infections in children, it was found that the placebo group, receiving hypertonic saline solution (twice daily) also produced a favourable response compared to those receiving no treatment31.

P eople who receive a Covid booster dose in the UK next month will be among the first in the world to receive Moderna's dual-variant vaccine, which protects against two strains of the virus.But . Thus, eligibility criteria were designed carefully to investigate a clearly defined, homogeneous study population of low-risk patients with a narrow age range. The analysis of sum symptom scores showed that the study population (ITT analysis set) suffered from moderate symptoms (mean valuesSD: 38.5810.04) on day 1 of the study (supplementary Table S5). During the course of the treatment, all study groups showed clear improvements of symptoms (Fig. Overall, none of the participating patients had clinically relevant increased values of body temperature (data not shown).

A TMPRSS2 inhibitor acts as a pan-SARS-CoV-2 prophylactic and therapeutic. Many elderly people as well asindividuals who are immunodeficient for various reasons do not respond to vaccines, and are in the need of other protective measures, said Kalle Saksela, MD, PhD, senior author of the study and a virologist at the University of Helsinki. 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.
