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 preclinical and clinical pathway.

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 is not a theoretical programme. The predecessor compound to VMD55 completed a Phase III clinical trial in Indonesia — demonstrating significant antiviral activity against dengue virus, a well-characterised safety profile, and the capacity to maintain endothelial homeostasis and prevent plasma leakage. VMD55 advances that proven scientific foundation under a globally structured development framework.

Clinical Evidence

Phase III completion — proven antiviral activity in human subjects.

The predecessor compound to VMD55 has already completed a Phase III clinical trial in Indonesia — providing a substantive clinical evidence base that meaningfully de-risks the VMD55 programme relative to a conventional early-stage asset. This is not a compound starting from first principles.

The trial concluded that the predecessor compound demonstrated antiviral activity against dengue virus, was well tolerated with no hepatotoxic or nephrotoxic effects, and was suitable for adoption as a standard treatment for dengue patients. VMD55 is being advanced on the foundation of that established evidence.

Phase III Clinical Trial — Indonesia

Predecessor Compound · Completed
Study Type Phase III clinical trial — Indonesia
Primary Finding Significant reduction in viral load following treatment; antiviral activity against dengue virus confirmed
Immunological Effect Potential immunomodulatory activity observed
Endothelial Effect Demonstrated capacity to maintain endothelial homeostasis — preventing plasma leakage, the defining complication of severe dengue
Safety Profile Well tolerated; no hepatotoxic or nephrotoxic effects identified; no other significant adverse effects observed
Study Conclusion The predecessor compound to VMD55 was concluded to be suitable for adoption as standard treatment for dengue patients in Indonesia

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.

Development Pathway

A defined route from pre-clinical to clinical milestone.

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.
