New ALS drug injected into spine begins human testing
NCT ID NCT07100119
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage study tests a new drug called LY4256984 in 32 people with sporadic ALS. The drug is injected into the spine to see if it is safe and how the body handles it. The main goal is to check for side effects, not yet to prove it works.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- LY4256984 (given as an injection into the spine)
- What this could lead to
- If successful, this could point toward a treatment that slows or controls ALS progression.
- What could go wrong
- This is a very early Phase 1 trial with only 32 people, focused on safety. It is too soon to know if the drug works, and it may cause side effects or fail in later studies.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Have a definite, possible, or probable diagnosis of sporadic amyotrophic lateral sclerosis (ALS) made by a physician experienced with the management of ALS * ALS symptom onset as determined by the Investigator within 24 months of Screening * Have a body mass index (BMI) within the range of greater than or equal to 18.0 and less than or equal to 35.0 kilogram per square meter (kg/m²) (inclusive) Exclusion Criteria: * Have a history or presence of medical illness including, but not limited to, any cardiovascular, renal, hepatic, gastrointestinal, respiratory, hematological, endocrine, psychiatric, or neurological disease, convulsions, or any clinically significant laboratory abnormality * Have a history of another neurodegenerative disease or significant dementia/severe cognitive problems * Have serum alanine aminotransferase (ALT), aspartate transferase (AST), or total bilirubin levels greater than 2 x upper limit of normal. * Have a significant renal impairment (estimated glomerular filtration rate \<60 milliliters per minute \[mL/min\]/1.73 m²). * Have a 12-lead electrocardiogram (ECG) abnormality at screening, in the opinion of the investigator, that increases the risks associated with participating in the study * Show clinically significant abnormalities in lumbar spine previously known or determined by screening lumbar X-ray or fluoroscopy (if performed)
