Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
AMX0114 is given by intrathecal injection, an injection in the lower back into the spinal canal, also known as lumbar puncture. This clinical trial is designed to test if the treatment is safe and tolerable by monitoring the incidence of adverse events, serious adverse events, dose limiting toxicities (DLTs), and incidence of abnormalities in clinical laboratory assessments, vital signs, physical and neurological examinations, and electrocardiograms (ECGs). This trial will also assess the effects of AMX0114 on biomarkers of ALS, including markers of neuronal death and neuroinflammation.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Active Treatment: AMX0114
AMX0114 will be administered once every 4 weeks by intrathecal bolus injection for a total of up to 4 doses. Treatment will be administered on Day 1, followed by repeat dosing every 4 weeks at approximately Day 29, Day 57 and Day 85.
AMX0114
Antisense oligonucleotides (ASOs) are a type of medicine that treats diseases by intercepting the mRNA messages sent within the cell, resulting in fewer specific proteins being made. AMX0114 is an ASO that targets the mRNA messenger that instructs the body to create a protein called calpain-2. Calpain-2 has been linked to the degeneration and death of neurons in many neurological diseases, including people living with sporadic ALS. AMX0114 is designed to reduce the levels of calpain-2, with the goal of slowing down the process that leads to neuron injury and death.
Placebo
Placebo drug will be administered once every 4 weeks by intrathecal bolus injection for a total of up to 4 doses. Treatment will be administered on Day 1, followed by repeat dosing every 4 weeks at approximately Day 29, Day 57 and Day 85.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Male or female, at least 18 years of age.
3. Diagnosis of clinically definite or clinically probable ALS, made by a physician who is experienced with management of ALS.
4. Time since onset of first symptom of ALS should be \<24 months prior to beginning the study. Date of ALS symptom onset is defined as the onset of weakness (in the limbs, bulbar region, or trunk).
5. If the participant is to be treated with riluzole and/or edaravone before or during the trial, then treatment must be previously started and maintained at a stable regimen for at least 30 days prior to starting the study and through the end of the study.
6. Women of childbearing potential (e.g., not post-menopausal for at least one year or surgically sterile) must agree to use an acceptable birth control method for the duration of the trial and 60 days after the last dose of Study Drug or be of non-childbearing potential.
7. Female participants or female partners of male participants must not be pregnant or plan to become pregnant for the duration of the trial and for up to 90 days after the last dose of Study Drug.
8. Male participants must agree to abstain from sperm donation for the duration of the trial and practice contraception with a female partner, for at least 90 days after last dose of Study Drug.
Exclusion Criteria
2. SVC less than 75%.
3. Abnormal liver function defined as aspartate aminotransferase and/or alanine aminotransferase \> 3 times the upper limit of normal (ULN) and/or total bilirubin \> 1.5 times the ULN (obtained within 4 weeks of first dose) except when a result of Gilbert syndrome.
4. Abnormal renal function defined as estimated glomerular filtration rate (eGFR) \< 60 mL/min/1.73m2.
5. Other laboratory abnormalities, including abnormalities in platelet count, international normalized ratio, prothrombin time, and activated partial thromboplastin time.
6. Pregnant women (confirmed by a pregnancy test within 7 days prior to first dose) or women currently breastfeeding.
7. Current or previous clinically significant, unstable medical condition (other than ALS), that in the opinion of the Investigator could affect a participant's safety or ability to comply with the study.
8. Significant abnormalities in physical/neurological examination, vital signs, or electrocardiogram (ECG), which in the opinion of the Investigator could affect the safety of the participant.
9. Presence of unstable psychiatric disease, cognitive impairment, dementia or substance abuse that could affect the participant's ability to provide informed consent or comply with study procedures.
10. Current or previous enrollment in another trial involving use of an investigational therapy, in most cases within 30 days after the last dose of the study drug, prior to starting this study.
11. Current or previous treatment with small interfering ribonucleic acid, stem cell therapy, any ASO or gene therapy.
12. Any contraindications for lumbar puncture or repeated intrathecal injection and/or underlying disorders that could be affected by intrathecal injections.
13. Prior severe reaction or known hypersensitivity to any part of the Study Drug.
