About this trial

This study will examine what happens when patients with amyotrophic lateral sclerosis (ALS) are given an investigational medication (study drug) known as LTX-002. Specifically, the researchers will be looking at safety, tolerability (if someone has any side effects from the drug), pharmacokinetics (what the body does to the study drug) and pharmacodynamics (what the study drug does to the body). The study will also investigate the effect of the drug on indicators of the severity of ALS, such as markers in blood and in the cerebrospinal fluid (the fluid that surrounds the brain and spinal cord, CSF) and on measures of the participant's ability to move, speak, and breathe.

Eligibility criteria

Qualifiers

Diagnosis of ALS per Gold Coast criteria

ALS symptom onset less than 36 months prior to Screening

Slow vital capacity ≥ 50% of predicted value

Body mass index ≥18 and ≤40 kg/m2

Disqualifiers

Current evidence or history of a clinically significant medical condition that, in the Investigator's judgement, would impact the participant's safety, interpretation of study results, or place the participant at high risk of poor treatment compliance or of not completing the study

History of brain or spinal abnormalities on magnetic imaging (MRI) or computed tomography (CT) that might interfere with the lumbar puncture (LP), cerebrospinal fluid (CSF) circulation or safety assessments

Prior treatment with antisense oligonucleotide (ASO), small interfering RNA, stem cell therapy, or gene therapy for any indication

Tracheostomy
