The Challenge

The blood-brain barrier
is medicine's hardest wall

The brain's protective barrier blocks pathogens — but also nearly every therapeutic we try to deliver. Solving this unlocks treatments for conditions that have defeated medicine for decades.

BBB
Selective Exclusion
Tight junction proteins, efflux transporters, and restricted transcytosis block the vast majority of therapeutic molecules from reaching brain tissue. The barrier is exquisitely selective — and ruthlessly effective.
CNS
Unmet Need
Alzheimer's, Parkinson's, glioblastoma, and rare neurological disorders remain largely untreatable — not because we lack effective molecules, but because we cannot deliver them where they need to go.
AI
New Frontier
Computational modelling of BBB receptor biology, transporter dynamics, and transcytosis kinetics is opening unprecedented design space for delivery systems built on the brain's own transport machinery.

The Opportunity

A $35 billion market
waiting for a key

The BBB is the single greatest bottleneck in neurotherapeutics. Whoever solves delivery unlocks not just Alzheimer's — but the entire CNS drug pipeline.

$35B+
CNS Drug Delivery Market by 2030
Driven by aging populations and a deepening pipeline of molecules that work — if they could only reach the brain.
98%
Failure Rate at the BBB
The barrier is the chokepoint, not the molecule. A platform that cracks this problem captures disproportionate value.

Platform Licensing Precedents
BBB delivery platforms have commanded $100M–$1B+ valuations and licensing deals from major pharma.
The Engine

NeuraPass discovers what
wet lab alone cannot

A computational discovery engine that models BBB biology at molecular resolution — identifying optimal delivery platforms before a single synthesis is committed.

AI Discovery Platform

From receptor landscape to validated candidate

NeuraPass integrates multi-scale BBB datasets — receptor interaction dynamics, transporter kinetics, endothelial transcriptomics — to predict which carrier architectures will actively cross the barrier. It is receptor-agnostic, modality-agnostic, and designed to discover platforms, not optimize a single chemistry.

Development Path

From computation
to clinic

Every candidate NeuraPass identifies follows a rigorous validation ladder — de-risking at each stage before the next dollar is spent.

01

NeuraPass Discovery

Computational screening of carrier-receptor pairings across the BBB landscape. Thousands of candidates evaluated in silico to identify the highest-confidence architectures for active transcytosis.

In Progress
02

3D BBB-on-Chip Validation

Physiologically relevant in vitro models with real-time TEER measurement and flow-mimicked cerebral vasculature. Validates barrier integrity, carrier uptake, and transcytosis before animal studies.

In Progress
03

In Vivo Proof of Concept

BBB crossing and brain parenchyma delivery confirmed in animal models. Pharmacokinetic profiling, biodistribution, and preliminary efficacy readouts in relevant disease models.

Planned
04

IND-Enabling Studies

GLP toxicology, GMP manufacturing scale-up, and regulatory dossier preparation. The bridge from preclinical validation to first-in-human clinical trials.

Planned
05

Phase I Human Trials

First-in-human safety and proof-of-mechanism studies. Demonstrating BBB penetration and therapeutic payload delivery in patients with CNS disease.
