Pipeline

Two assets. One mission: a younger brain.

Our lead medicine rejuvenates the healthy aged brain and is entering formal safety studies. A second, purpose-designed asset is in active efficacy testing. Both ride the same validated intranasal mRNA-LNP delivery platform.

Bars show the furthest stage each program has reached. Both run on one intranasal mRNA-LNP delivery platform. Preclinical data are not yet peer reviewed; no L3 Labs product has been tested in humans.

L04 · Lead asset

Brain rejuvenation.

L04 is an intranasal mRNA medicine that drives the brain's master regulator of synaptic plasticity, neurogenesis and neuronal survival. In preclinical studies it boosted the birth and growth of new neurons in the aged hippocampus, improved memory in healthy aged mice, and protected existing neurons in an aggressive familial-Alzheimer's model.

L05 · Second-generation cargo

Brain rejuvenation, a complementary mechanism.

A second brain-rejuvenating medicine that works through a different, complementary mechanism to L04. Purpose-designed on the same intranasal platform and now in active efficacy testing. The target is undisclosed.

The regulatory on-ramp: MCI & early Alzheimer's

Longevity is the mission; the clinic is the path. We enter humans through mild cognitive impairment and early Alzheimer's disease, indications with clear, accelerable regulatory pathways and validated, mechanism-matched biomarker endpoints. Read our Alzheimer's & MCI strategy →
