Strengthening Executive Function in neurodevelopmental conditions

Anaka is developing AKA1315, a first-in-class, clinical-stage therapy in parallel development for executive function impairment in ADHD, Down syndrome (DS-EF) and autism, with pipeline-in-a-product franchise potential.

The challenge

A significant, unaddressed need across
neurodevelopmental conditions

Executive function (EF), the brain's control system governing working memory, inhibition, cognitive control, planning, and attention, is significantly impaired in ADHD, Down syndrome, and autism. Across all three, no approved therapy is designed to directly stabilize the EF network itself.

ADHD

  • ·23M individuals in the US
  • ·20-30% of stimulant-treated children experience clinically significant nightly insomnia

Unmet needMany treatments exist, but none also improves sleep

Down syndrome executive function (DS-EF)

  • ·70%+ of individuals with DS have significant EF impairment
  • ·Impacts independence, learning, communication, and sleep

Unmet needNo approved treatment for EF impairment

Autism spectrum disorder

  • ·8M individuals in the US
  • ·Many current options cause sedation or stimulant-type effects, with limited EF benefit

Unmet needNo approved treatment for EF impairment

Current treatments fall short

All existing options (stimulants, reuptake inhibitors, α2A agonists, and psychotropics) target monoamines, not the underlying prefrontal network dysfunction believed to drive EF impairment. None is designed to directly stabilize the affected neuronal firing. None improves sleep.

Down syndrome specialists describe a successful executive-function therapy as a potential blockbuster, and say better executive function is among the very top priorities families ask for.

Our approach

AKA1315: stabilizing the brain's control system

Over three decades, co-founder Mario Sanchez systematically observed that compounds stabilizing neuronal firing produced consistent improvements in executive function across ADHD, Down syndrome, and autism, while standard neurotransmitter-targeting drugs did not. This hypothesis led directly to identification of AKA1315.

The driver of EF impairment

Unstable prefrontal network activity

EF impairment reflects a pattern of unstable prefrontal cortex (PFC) network activity, characterized by:

  • ·Inconsistent attention and working memory
  • ·Poor cognitive control and inhibition
  • ·Worsening with sleep disruption and stress
  • ·Shared downstream network instability across ADHD, DS, and autism, not a single upstream cause

Our mechanism

Direct neuronal firing stabilization

AKA1315 directly stabilizes neuronal firing via dual-state ion channel modulation:

  • ·Reduces pathological firing variability
  • ·Restores signal-to-noise in PFC networks
  • ·Supports stable prefrontal network function
  • ·No mechanistic overlap with any other active Down syndrome program in development

AKA1315 is the only therapy in development with early human signal across executive function, sleep, and mood in more than one neurodevelopmental condition, and one of the lowest regulatory-risk profiles of any active program in this space.

Why AKA1315

A development plan built to de-risk a historically difficult category

Neurodevelopmental drug programs typically fail for well-understood reasons: poorly characterized mechanisms, high placebo response, and unproven formulations. AKA1315's plan is designed to retire each of those risks in sequence, before the next dollar is spent.

01

Known safety profile

AKA1315 combines components with decades of established clinical safety data, removing the discovery-stage toxicology risk that sinks many CNS programs.

02

One new variable at a time

The modified-release formulation is the single genuinely new element in the program, gated by an objective pharmacokinetic readout before advancing.

03

Early human signal already observed

Consistent, early signals in executive function, sleep, and mood have been observed across three distinct conditions, ahead of the controlled studies designed to confirm them.

04

Staged, gated development

Each phase is tied to pre-committed, objective go/no-go criteria, so capital is only deployed once the prior risk has been retired.

Programs

A single asset with
Executive Function franchise potential

AKA1315 targets the EF network layer shared across multiple neurodevelopmental conditions. ADHD and Down syndrome executive function (DS-EF) are being developed in parallel as lead indications, with autism spectrum disorder as a follow-on franchise opportunity built on the same mechanism.
