Loading SynMiR experience

Restoring therapeutic sensitivity.

SynMiR is developing synthetic microRNA-based therapeutics designed to address drug resistance in melanoma.

Cancer rarely escapes through one pathway.

Resistance is multi-factorial. Syn-miRs are designed to modulate multiple resistance-associated genes at once.

Local delivery. Sustained exposure.

A PLGA-based locoregional delivery strategy is being developed to concentrate activity where residual disease may emerge.

From academic discovery to biotech asset.

SynMiR is building the preclinical data package required for investor, regulatory and pharma-partner readiness.

A synthetic microRNA approach to multi-pathway resistance.

SynMiR designs proprietary Syn-miRs: synthetic RNA sequences engineered to act on networks of genes associated with tumour survival and therapeutic escape.

Multi-target design

Unlike single-target approaches, Syn-miRs are designed to engage multiple molecular nodes involved in resistance.

Bioinformatic generation

The platform uses proprietary computational logic to generate miRNA-like sequences tailored to disease-relevant gene networks.

Pipeline scalability

The same design logic can support future oncology indications beyond the first melanoma candidate.

Current development is preclinical. Further validation is required before clinical use.

Melanoma relapse is driven by resistance.

Targeted therapies have improved outcomes, but acquired resistance remains a major clinical and strategic challenge.

1

Initial response

BRAF/MEK targeted therapies can produce meaningful initial responses in selected melanoma patients.

2

Acquired resistance

Over time, tumour cells may activate alternative pathways and bypass single-axis inhibition.

3

Unmet need

Reducing recurrence and delaying resistance remain key goals in melanoma treatment innovation.

Designed for local control, not systemic exposure.

SynMiR is pursuing locoregional delivery using PLGA-based controlled release to improve local exposure while limiting systemic distribution.

Systemic RNA delivery challenges

  • Rapid degradation
  • Potential immune activation
  • Off-target exposure
  • Narrow therapeutic window

Locoregional PLGA strategy in Melanoma

  • Delivery at or near the surgical site
  • Controlled release over weeks
  • Reduced systemic exposure by design
  • Potential fit with surgically accessible melanoma settings

Early evidence supports continued development.

SynMiR has generated preliminary molecular and preclinical evidence. The next milestone is to validate the optimized delivery system in vivo.

Molecular PoC

Target engagement rationale

Initial molecular studies support the mechanism-of-action hypothesis and target-network engagement.

In vitro

Activity in resistant melanoma models

Syn-mel-10-8 showed strong phenotypic activity in resistant melanoma cell models during internal preclinical testing.

In vivo Study I

Initial in vivo signal

A first in vivo study using a standard delivery system showed tumour-size reduction during treatment exposure, highlighting the need for sustained delivery.

In vivo Study II

Optimized PLGA delivery

A second in vivo study is focused on PLGA-based sustained local release and improved exposure at the target site.

All results are preclinical and investigational. SynMiR has not been evaluated in humans and is not approved for clinical use.

18 months to a value-inflecting preclinical package.

The current plan focuses capital on milestone-driven de-risking rather than broad exploratory research.

Phase 1Months 1–3

IP & asset control

Exclusive license execution and IP/FTO workstream consolidation.

Phase 2Months 3–9

Delivery validation

PLGA manufacturing, QC and in vivo efficacy validation with optimized delivery.

Phase 3Months 6–12

Safety package

Early toxicology, dose range and tolerability workstreams with external partners.

Phase 4Months 12–18

Investor-ready data room

Data package assembly, indication strategy, regulatory pre-submission preparation and pharma BD outreach.

A focused entry market with expansion potential.

SynMiR’s initial strategy is designed around a surgically accessible melanoma setting, with potential expansion into broader adjuvant and combination opportunities after de-risking.

Tier 1

Focused entry

Injectable or locoregional melanoma settings where delivery feasibility and unmet need are clearest.

Tier 2

Adjuvant expansion

Potential future use in post-surgical, high-risk BRAF-mutated melanoma populations, subject to clinical validation.

Tier 3

Platform optionality

Longer-term potential to expand into combination strategies or additional oncology indications after delivery and safety validation.

* Market estimates and indication prioritization are under validation through KOL interviews, clinical input and investor due diligence.

Built for pharma partnership.

SynMiR is not building a commercial salesforce. The business model is based on asset de-risking, partnership, licensing and co-development.
