What We Do

Solving the Delivery Problem

Founded in 2021 and headquartered in Cambridge, UK, Dianoya is solving the fundamental challenge of neuro-drug development: the Blood-Brain Barrier. By hijacking the body's natural iron transport mechanism, we turn large molecule therapeutics into brain-penetrant precision medicines.

Why BACE1?

Previous BACE inhibitors (Merck, Lilly, Janssen) failed due to peripheral target engagement causing cognitive decline. Our brain-selective delivery achieves 40:1 brain:plasma exposure, enabling CNS-specific Aβ reduction without systemic BACE1 inhibition. Pre-IND meeting scheduled Q1 2026.

The Mechanism

Engineered to escape
the Lysosome

Unlike high-affinity TfR binders that trigger lysosomal degradation, our bivalent shuttle uses moderate affinity (Kd ~0.3nM) with pH-dependent release kinetics, validated across three NHP studies showing consistent parenchymal distribution and no reticulocyte depletion at therapeutic doses.

Business Strategy

Pipeline-First Growth

We focus wholly-owned development on high-value CNS targets where brain delivery is the primary failure mode. Platform partnerships are opportunistic and limited to indications outside our core focus (e.g., neuro-oncology).

Proprietary Focus

  • Neurodegeneration programmes focus on wholly-owned assets for Alzheimer's and Parkinson's.
  • Value Capture strategy retains full rights through clinical proof-of-concept.

Strategic Partnering

  • Non-Core Indications are addressed by out-licensing the platform for rare disease & oncology.
  • Economics leverage upfront fees + milestones to fund the proprietary pipeline.
