VMD55 Programme

One asset.
Global exclusive rights.

VMD55 is Aedion's lead asset — a dengue antiviral programme held under a globally structured exclusive licence, advancing through a defined pathway — informed by a completed Phase III clinical trial in the predecessor compound, now preparing Phase 2a for VMD55.

Lead Asset

VMD55 — programme overview.

VMD55 is Aedion's lead asset, grounded in the pioneering scientific work of Professor Max Reynolds and held under a global exclusive licence and supply framework. Aedion is the single authoritative global holder of the programme — responsible for its development, protection, standardisation, and clinical advancement.

VMD55 builds on prior clinical work. In a randomised, double-blind, placebo-controlled Phase III trial in Indonesia, patients treated with MAC, the predecessor material to VMD55, cleared dengue virus significantly faster than placebo (p=0.013), and the material was well tolerated. Aedion is advancing VMD55 from that clinical observation under a globally structured development framework; demonstrating chemical continuity between VMD55 and the trial material is a programme objective.

Clinical Evidence

Phase III completion — a clinical observation in patients.

The predecessor compound to VMD55 has already completed a Phase III clinical trial in Indonesia — giving the VMD55 programme a clinical starting point that a conventional early-stage asset does not have.

In a randomised, double-blind, placebo-controlled trial (532 randomised, ~450 analysed per protocol), patients treated with MAC cleared dengue virus significantly faster than placebo (p=0.013), with an accompanying immunomodulatory signal. The material was well tolerated across three human studies. The mechanism by which this occurs is not yet established: in-vitro work demonstrates direct virucidal activity, but only at concentrations far above those achievable by oral dosing, and a host-response mechanism remains a hypothesis. Establishing the mechanism, and demonstrating chemical continuity between the current material and the material used in 2013, are the two objectives of our current programme.

Phase III Clinical Trial — Indonesia

Predecessor Compound · Completed
Study Type Phase III clinical trial — Indonesia
Primary Finding Patients treated with MAC cleared dengue virus significantly faster than placebo (p=0.013); 532 randomised, ~450 analysed per protocol
Immunological Effect An accompanying immunomodulatory signal; not yet established as the mechanism
Mechanism Not yet established; a host-response mechanism is a hypothesis the Phase 2a is designed to test
Safety Profile Well tolerated across three human studies
Next Step Phase 2a of VMD55, designed to test whether the clinical observation holds, and by what mechanism

Phase III clinical trial conducted in Indonesia. Results pertain to the predecessor compound to VMD55 and do not constitute regulatory approval of VMD55. Aedion Therapeutics is advancing VMD55 through an independent development and regulatory pathway. Chemical continuity between VMD55 and the trial material has not yet been established.

Development Pathway

Built on Phase III evidence — advancing VMD55 to Phase 2a.

Aedion is advancing VMD55 through a rigorous, systematically planned development pathway appropriate for priority dengue-endemic markets and designed to maintain internationally credible regulatory standards throughout.

Development Mandate

Five areas of responsibility define Aedion's role.

Aedion was not created to start from zero. Its mandate is specific: to secure, protect, standardise, and advance an existing body of scientific work through the commercial, legal, and clinical infrastructure needed to make it a globally credible therapeutic asset.

01
Rights & Supply Management
Secure and manage the global exclusive rights, know-how, and supply structure for VMD55 — establishing Aedion as the single authoritative global holder of the programme across all markets.
02
Intellectual Property Strategy
Protect and continuously expand the IP estate surrounding the programme. Build a defensible, long-term IP position that supports clinical development, commercialisation, and investor confidence.
03
Product Standardisation & Quality
Standardise and develop VMD55 to internationally credible GMP-aligned quality standards — appropriate for regulatory submissions in priority dengue-endemic markets and beyond.
04
Regulatory & Clinical Execution
Advance the programme through regulatory, preclinical, and clinical milestones in priority markets. Build a clinical track record that underpins long-term asset value and regulatory credibility.
05
Platform Value Creation
Create a platform for long-term value in dengue and adjacent viral disease opportunities. VMD55 is the beginning — Aedion is positioned to become a durable infectious disease company over time.

Rights & IP Structure

A coherent global framework built for long-term defensibility.

Licence Structure
Global Exclusive Licence
Aedion holds exclusive global rights to VMD55 in dengue under a structured licence and supply framework. There is a single global holder of the programme — Aedion Therapeutics.
IP Estate
Active & Expanding
The intellectual property surrounding VMD55 is under active protection and ongoing strategic expansion. Aedion's IP strategy is designed to create durable barriers to entry and underpin long-term commercial value.
Know-How
Centralised & Secured
The scientific know-how underlying the programme has been centralised within Aedion's legal structure. This encompasses the full body of prior work established under Professor Max Reynolds' research programme.

Platform Potential

VMD55 is the beginning — not the ceiling.

Long-Term Vision
From a single asset to a durable infectious disease platform.

While Aedion's immediate focus is the disciplined development of VMD55 in dengue, the company is structured from the outset to become a broader platform in mosquito-borne and viral disease therapeutics.

The expertise, infrastructure, regulatory relationships, and scientific credibility built through the VMD55 programme create a natural foundation for expansion into adjacent indications and assets over time.

Current Focus

What Aedion is doing now, and what funding enables.

Aedion holds global exclusive rights and supply to VMD55 — establishing the legal and commercial foundation from which the development programme advances. Current activities are focused on product standardisation and preparing for the Phase 2a clinical stage.

The current raise is directed at completing these foundational steps and funding the next clinical milestone. Full detail on the use of proceeds, development plan, and capital requirements is available in the Data Room under NDA.
