Regulatory discussions are underway, including pre-IND discussions with the FDA, to ensure comprehensive safety and toxicological testing before human clinical trials commence.

4. Technology & Innovation

Technology Stack

ReBio Pharma's core innovation is its proprietary SiSu® platform, a novel formulation technology for sustained-release drug delivery.

Core Platforms and Technologies: The SiSu® platform is a therapeutic amplifier that enables the design of targeted, locally delivered conjugates.

Proprietary Developments: The platform utilizes a liquid polymer that, upon subcutaneous injection into an aqueous environment, solidifies into a soft depot (implant). This implant then releases the medicinal agent evenly and consistently over an extended period (one month to a year) from a single injection.

Scientific Methodologies: The technology aims to provide precise, programmable drug exposure, addressing safety and efficacy challenges unmet by other sustained-release approaches.

Technical Capabilities: ReBio Pharma manufactures its polymers in-house in both the UK and Finland.

Patents and Intellectual Property

The company holds key intellectual property related to its drug delivery formulations. ReBio has 10 patent documents, with 5 granted patents. Pending patent applications include "Compositions for ophthalmic care" with publication IDs EP-4294366-A1, US-20240130997-A1, and US-20240226053-A9, with a first filing date of February 19, 2021. An earlier patent application pertaining to the treatment of type 2 diabetes was submitted in 2017.
