FUNCtion ALS: Aiming to Restore UNC13A Function in People Living With ALS (FUNCtion ALS)

8. september 2026 oppdatert av: Trace Neuroscience, Inc.

A Randomized, Double-Blind, Placebo-Controlled, Phase 1 / 2 Trial Evaluating the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Exploratory Efficacy of TRCN-1023 Administered by Intrathecal Injections to Adult People Living With Amyotrophic Lateral Sclerosis

The FUNCtion Amyotrophic Lateral Sclerosis (ALS) trial is a randomized, double-blind, placebo-controlled Phase 1/2 trial to evaluate the safety and tolerability of TRCN-1023 in adults living with ALS. TRCN-1023 is an investigational medicine given as a single injection into the fluid surrounding the spine (intrathecal injection). The trial will also assess how the body processes the drug and whether it shows early signs of benefit over 24 weeks.

Detaljert beskrivelse

TRCN-1023 is an investigational medicine designed to restore the function of a protein called UNC13A, which becomes disrupted in most people with Amyotrophic Lateral Sclerosis (ALS) due to a breakdown in how nerve cells process genetic information. This trial is designed to evaluate the safety and tolerability of TRCN-1023 given as a single injection into the fluid surrounding the spine, and to identify the best dose to carry forward into future studies. TRCN-1023 stays in the brain and spinal cord long enough that it may only need to be administered once every 24 weeks. The trial will also assess how the body processes the drug, whether it engages its intended target, and its effects on disease progression, physical function, and quality of life.

  • ALS symptoms began within the past 24 months
  • Able to perform breathing tests: slow vital capacity (SVC) with consistent results, with breathing capacity of at least 60% of the expected value
  • Able and willing to meet all study requirements, including travel to the study site, brain magnetic resonance imaging (MRI) scans, lumbar punctures, and blood draws
  • Able and willing to use wearable sensors and complete speech assessments at home
