SAN DIEGO, Jan. 11, 2022 (GLOBE NEWSWIRE) -- Revelation Biosciences Inc. (NASDAQ: REVB) (the “Company” or “Revelation”), a clinical-stage life sciences company that is focused on the development of immunologic-based therapies for the prevention and treatment of disease, today announced it has observed significant decrease in viral load with prophylactic treatment of REVTx-99 in three independent in vitro single cell-based assay models of SARS-CoV-2 infection.
In addition, the company announced that they have completed their business combination with Petra Acquisition, Inc. and will trade under “REVB” and “REVBW” beginning today, January 11, 2022.
How REVTx-99 Works
REVTx-99 binds to toll-like receptor 4 (TLR4), stimulating and inducing host-directed factors that augment the production of protective cytokines including interferons and interferon-related proteins which contributes to the establishment of an anti-viral state regardless of virus type, strain, or variant.
The Studies and Findings
REVTx-99 was assessed for prophylactic anti-viral activity against SARS-CoV-2 Delta infection in three separate cell lines, each expressing sufficient levels of ACEII and TLR4, receptors required to sufficiently demonstrate viral infection as well as REVTx-99 activity, respectively.
These studies were conducted on behalf of Revelation by a third-party contract research laboratory specializing in viral activity assays.
Revelation is continuing to develop and optimize in vitro and in vivo models to define TLR4 stimulation in response to REVTx-99, and identify a dose range for optimal anti-viral efficacy against SARS-CoV-2, additional variants such as Omicron, and other viruses including rhinovirus, respiratory syncytial virus, and influenza. Additional in vitro anti-viral dose response results for REVTx-99 will be used to inform the design for our planned preclinical studies.
"These results, along with our early clinical study results, (Revelation study REV-NHV01), suggest REVTx-99 creates an anti-viral state in relevant cell types and encourage us to continue our work to demonstrate the anti-viral potential for REVTx-99, especially considering the continuous introduction of new variants, such as Omicron”, said James Rolke, Chief Executive Officer of Revelation. “With new, more infective SARS-CoV-2 variants emerging, and the continued impact of COVID-19 on the daily lives of people around the world, we remain focused on rapidly advancing this urgently needed protective therapy to fill the current unet need."
During the 2019-2020 season, the CDC estimates that influenza was associated with 38 million illnesses, 18 million medical visits, 405,000 hospitalizations, and 22,000 deaths. Globally, COVID-19 is responsible for more than 5 million deaths, with thousands of people dying every day.

REVTx-99 is a proprietary intranasal drop formulation in development for the prevention or treatment of respiratory viral infection and is broadly applicable to most infectious viruses including influenza A, influenza B, parainfluenza, rhinovirus, respiratory syncytial virus (RSV), SARS-CoV-2 and its variants. The active ingredient in REVTx-99 stimulates the nasal (mucosal) innate immune system via interaction with toll-like receptor 4 (TLR4) to produce protective cytokines including interferons and interferon-related proteins. These protective cytokines work in concert to blunt the ability of an invading virus to proliferate and survive. Phase 1 data showed REVTx-99 to be well-tolerated and to significantly increase intranasal protective cytokines.
In addition, to viral infection, REVTx-99 is also being developed for management of allergic rhinitis symptoms and chronic nasal congestion without polyps. REVTx-99 upregulates a protein which competes for the native eotaxin receptor, CCR3, preventing eotaxin from recruiting eosinophils, thereby reducing recruitment of Th2 cells, and attenuating the allergic response.
About Revelation Biosciences Inc.
Revelation Biosciences, Inc. is a clinical-stage life sciences company focused on the development of immunologic-based therapies for the prevention and treatment of disease. Revelation has several product candidates in development. REVTx-99, the lead therapeutic candidate, is an intranasal immunomodulator to prevent or treat infections caused by various respiratory viruses such as SARS-CoV-2, including its variants, influenza A and B, parainfluenza, rhinovirus, and RSV. REVTx-99 is also being developed for other indications such as: allergic rhinitis and chronic nasal congestion. REVTx-200 is an intranasal immunomodulator adjunct to be used in combination with an intramuscular vaccination for more complete immunity. REVTx-200 is based on the same technology used in REVTx-99. In addition to Revelation’s therapeutic pipeline, Revelation is also developing REVDx-501, a rapid home use diagnostic that can be used to detect any respiratory viral infection, regardless of virus type or strain, without the need for specialized instrumentation.
