Revelation Biosciences Inc. Announces First Patient Enrolled and Dosed in Phase 1b Clinical Study of REVTx-99 for the Treatment of Allergic Rhinitis


SAN DIEGO, Jan. 18, 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 that the first patient has been enrolled and dosed in a Phase 1b clinical study to evaluate the potential utility of REVTx-99 for treating patients with allergic rhinitis and patients with chronic nasal congestion without polyps. The clinical study is being conducted in Australia.

“In the US, approximately 8% of adults and 7% of children have allergies that cause symptoms of allergic rhinitis, also called hay fever, and patients with allergic rhinitis have a threefold greater risk of developing asthma. The risk of developing asthma increases with more severe and persistent allergic rhinitis,” said James Rolke, Chief Executive Officer of Revelation. “REVTx-99 is being developed as a therapy for the millions of people who suffer from these symptoms each year – including those related to chronic nasal congestion, in which patients with severe cases may require invasive sinus surgery. The initiation of patient enrollment is an important step in our efforts to provide patients with safe and effective treatments for these chronic issues.”

The Phase 1b, randomized, double-blind, placebo-controlled, crossover design study is expected to enroll approximately 28 participants. The primary endpoint is to evaluate the effects of REVTx-99 versus placebo on safety and tolerability. Key secondary endpoints include allergy symptoms (Total Nasal Symptom Score) and peak nasal inspiratory flow elicited by nasal allergen challenge. The study will have two cohorts: one cohort will receive study drug before the nasal allergen challenge (the prophylactic cohort) and the second cohort will receive study drug after the nasal allergen challenge (the treatment cohort).

The company expects the topline data in the first half of 2022.

About REVTx-99

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 asal 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 Allergic Rhinitis

Allergic rhinitis also called hay fever, is a very common disorder that affects millions of patients annually and the hallmark complaint of nasal obstruction significantly impacts the quality of life. It is an allergic reaction to tiny particles in the air called allergens. Symptoms include sneezing, nasal congestion and irritation of the nose, throat, mouth and eyes. Some treatment options may include antihistamines, anti-inflammatory nasal sprays, anti-leukotrienes, and surgery. Allergic rhinitis can lead to complications in some cases: nasal polyps, sinusitis, and middle ear infections. People with severe chronic nasal congestion sometimes need surgery.


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.
