PART I Business Revelation Biosciences is a clinical-stage biopharmaceutical company developing therapeutics and diagnostics that modulate the innate immune system via TLR-4 stimulation Overview and Pipeline Revelation develops TLR-4 modulating therapeutics, with a pipeline focused on organ disease, infection prevention, vaccine adjuncts, and food allergies, while discontinuing prior programs - The company's therapeutic candidates are based on the active ingredient PHAD®, a synthetic version of MPLA, which stimulates TLR-4 to modulate the innate and adaptive immune response75 Development Pipeline Status | Therapeutic Candidate | Indication | Discovery | Preclinical | Phase 1 | Phase 2 | Next Milestone | | :--- | :--- | :--- | :--- | :--- | :--- | :--- | | REVTx-300 | Acute/chronic kidney disease | ✔ | ✔ | | | Initiate Phase 1a* study | | REVTx-100 | Prevention of post surgical infection | ✔ | ✔ | | | Initiate Phase 1a* study | | REVTx-200 | Adjunct to IM vaccine | ✔ | ✔ | | | Readout from PEITHO nonclinical study | | REVTx-99b | Food allergies | ✔ | ✔ | | | Initiate non-clinical study | - The company discontinued clinical development of REVTx-99a for respiratory viral infections in June 2022 after a Phase 2b study did not meet its primary endpoint95 - Development of REVTx-99b for chronic nasal congestion and allergic rhinitis was halted in July 2022 after a Phase 1b study met safety endpoints but not exploratory efficacy endpoints96 - Development of the REVDx-501 diagnostic has been suspended to focus resources on therapeutic candidates99176 Key Therapeutic Programs Key therapeutic programs leverage PHAD® for acute/chronic organ diseases, infection prevention, vaccine adjuncts, and food allergies, with Phase 1a studies for REVTx-300 and REVTx-100 planned for H2 2023 - In a nonclinical rat model for kidney disease, REVTx-300 demonstrated a statistically significant reduction in renal cortical fibrosis at doses of 0.3 mg/kg (44% reduction) and 0.9 mg/kg (58% reduction) compared to the vehicle-only group7788 - The company plans to initiate a combined Phase 1a clinical study in healthy volunteers for both REVTx-300 and REVTx-100 in the second half of 2023 to evaluate safety and investigate biomarkers8285146 - REVTx-100 is being developed under an exclusive worldwide license agreement with Vanderbilt University for treating or preventing infections, utilizing US patent 11,389,46583187 - REVTx-200 is being developed as an intranasal therapy to be administered with traditional IM vaccines to potentially provide a more complete immunization by stimulating a mucosal immune response86 Manufacturing, IP, and Competition Revelation relies on third-party manufacturing, faces single-source supplier risk for PHAD®, holds several patent applications, and operates in an intensely competitive biopharmaceutical industry - The company does not own or operate manufacturing facilities and relies on third-party CMOs for production of its product candidates184 - There is only one supplier for the active ingredient PHAD®, Avanti Polar Lipids, Inc., and the company does not have a long-term supply agreement in place, though it has purchased enough material for planned clinical studies184 - As of March 21, 2023, the company's patent portfolio includes three U.S. provisional patent applications (for REVTx-300, REVTx-99b, and a new drug program) and three international PCT patent applications (two for REVTx-99b and one for REVDx-501)197 - The company faces intense competition from multinational pharmaceutical companies and specialized biotechnology firms with greater financial, technical, and human resources177183 Government Regulation The company's products are subject to extensive FDA and international regulation, encompassing preclinical studies, clinical trials, manufacturing, marketing approval, and ongoing compliance with healthcare laws and reimbursement policies - Therapeutic product candidates must undergo a multi-phase approval process including preclinical studies, an Investigational New Drug (IND) application, and three phases of clinical trials to establish safety and efficacy before an NDA can be submitted to the FDA210213215 - The diagnostic candidate, REVDx-501, is regulated as a medical device and is expected to be subject to review under a de novo clearance pathway, which can be more rigorous than the 510(k) process228233 - The company's operations are subject to various U.S. healthcare laws, including the Anti-Kickback Statute, the False Claims Act, HIPAA for data privacy, and the Sunshine Act for transparency in payments to physicians244245248252257 - Commercial success depends on securing coverage and adequate reimbursement from third-party payors like Medicare, Medicaid, and private insurers, which is a complex and uncertain process260261262 Risk Factors The company faces substantial risks including limited operating history, net losses, going concern uncertainty, high development risks, reliance on third-party manufacturing, IP protection challenges, intense competition, commercialization hurdles, litigation, and regulatory changes - The company has a limited operating history, has incurred net losses since inception, and its financial statements raise substantial doubt about its ability to continue as a going concern without additional funding315316318 - The business is highly dependent on the success of its Program Products, which are in early stages of development and face a high risk of failure in clinical trials322332347 - Revelation relies on a single supplier, Avanti Polar Lipids, Inc., for PHAD®, the active pharmaceutical ingredient in its therapeutic candidates, and does not have a long-term supply agreement, posing a significant manufacturing risk367 -
