Non-invasive CNS delivery platform

Unlock the brain.Keep the molecule.

Apertum primes the blood-brain barrier with non-invasive stimulation—so systemic therapeutics reach the CNS without being redesigned.

Biology can work.
Delivery can fail.

The blood-brain barrier protects the brain—and blocks most therapeutic molecules from reaching useful exposure.

Apertum treats permeability as a platform problem. The goal is to unlock existing and next-generation therapeutics without redesigning the asset around the barrier.

The device is not
the product. Delivery is.

A clinical workflow built to fit around the therapeutic—not force the therapeutic to fit around the technology.

01

Prime

A 45-minute non-invasive stimulation session transiently increases BBB permeability.

02

Infuse

The device is removed and the existing therapeutic is administered through a standard systemic infusion.

03

Deliver

The temporary permeability window increases exposure inside the central nervous system.

04

Discharge

The workflow is ambulatory—with no sedation, shaving, implanted device or hospital stay.

Across species.
Into deep structures.

Systemic AAV–ARSA administration with Apertum treatment produced region-specific enzyme activity increases versus a no-opening control in non-human primates.

Research access

Follow the evidence further.

Prime a temporary delivery window for approved or clinical-stage compounds whose useful CNS exposure is limited by the barrier.

Platform value · Increase exposure without changing the compound.

Create a route for large biologics to enter the CNS while preserving the molecule’s binding architecture and systemic administration.

Platform value · Improve tissue-level antibody exposure.

Use BBB priming before systemic AAV delivery to investigate broader access to deep brain structures. AAV–ARSA is the platform’s current functional NHP signal.

Evidence anchor · Non-human-primate AAV–ARSA activity mapping.

Apply the same workflow to gene-replacement and nucleic-acid programs where distribution—not construct design—is the central constraint.

Platform principle · Keep the therapeutic design; change the access condition.

A measurable first step.
A platform beyond it.

The beachhead is brain oncology: use clinically planned resection to measure whether BBB priming changes drug exposure, then evaluate repeat-use safety.
