Revelation Biosciences Inc. Receives Approval to Start a Phase 1 Clinical Study of REVTx-99 an Experimental Treatment for COVID-19

MENLO PARK, Calif.--(BUSINESS WIRE)--#biotechnews--Revelation Biosciences Inc. (Revelation), a clinical stage life sciences company focused on the development of immunologic-based therapies for the prevention and treatment of disease, announced today that it has been granted approval by the Bellberry Human Research Ethics Committee (HREC) in Australia to conduct a Phase 1 clinical study of REVTx-99 in healthy volunteers (RVL-HV01 study). HREC approval permitted Revelation to complete the required Clinical Trial Notification to the Therapeutic Goods Administration. REVTx-99 is in development as an early treatment for SARS-CoV-2 Infection (COVID-19). RVL-HV01 is a single site, placebo-controlled, single dose, escalating dose study to determine the safety and tolerability of intranasal REVTx-99 in healthy adult volunteers. The study is expected to begin enrolling participants in Q4 2020.

"We are excited to announce the initiation of clinical development for REVTx-99, our first pipeline candidate to enter Phase 1 clinical study," said James Rolke, Chief Executive Officer of Revelation. �Due to the severity and high hospitalization rate of SARS-CoV-2 infection and the urgent need for effective treatments, we are looking forward to embarking on clinical development and rapidly advancing this therapeutic candidate.�

RVL-HV01 will enroll up to 32 participants in 4 cohorts. The primary endpoints are to determine the safety and tolerability of escalating intranasal doses of REVTx-99 in healthy adult volunteers and to determine the pharmacodynamic effect of REVTx-99 in healthy adult volunteers as measured by nasal and systemic cytokine levels throughout the course of treatment. There are multiple exploratory pharmacodynamic endpoints.

Revelation expects enrollment of RVL-HV01 to begin during the fourth quarter of 2020, with topline data early in the first quarter of 2021. After completion of this study, Revelation plans to initiate a Phase 2 study during the first half of 2021 in early stage COVID-19 patients at risk for hospitalization.

About REVTx-99

REVTx-99 is a proprietary intranasal formulation of phosphorylated hexaacylated disaccharide or PHAD, a synthetic version of monophosphoryl lipid A. SARS-CoV-2 viral proteins have been shown to block the production of interferons, a key part of the innate immune response to viral infection, resulting in worse outcomes. REVTx-99 acts by stimulating the innate immune response via interaction with toll-like receptor 4 (TLR4) and activation of the TIR-domain-containing adapter-inducing interferon-? (TRIF) pathway to produce protective cytokines including Type I and Type II interferons. The innate immune system is the first line of defense against invading pathogens such as bacteria and viruses. Toll-like receptors (TLRs) are associated with sentinel cells (e.g. macrophages, dendritic cells) and serve a vital role in the innate immune system response. TLRs recognize repeated molecular patterns associated with pathogens (PAMPS). When a pathogen invades a subject, TLRs recognize PAMPS as foreign and activate the innate immune response, inducing the production of numerous cytokines to combat the invading pathogen and stimulate the adaptive immune 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. The Company has several product candidates in development. REVTx?99, the lead therapeutic candidate, is an intranasal immunomodulator for the early treatment of SARS-CoV-2 infection. An expansion of REVTx?99 therapeutic indications is planned targeting early treatment and prevention of respiratory viral infection such as with influenza A or B, parainfluenza, and respiratory syncytial virus. 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 the Company�s therapeutic pipeline, Revelation is also developing REVDx-501, a rapid point of care diagnostic that can be used to detect any respiratory viral infection regardless of virus type without the need for specialized instrumentation.
