This study will evaluate the long-term safety and efficacy of participants enrolled in SPG302-ALS-101 with Amyotrophic Lateral Sclerosis (ALS)
This is an open-label extension study of SPG302-ALS-001 to investigate the long-term safety, tolerability, and efficacy of SPG302 administered orally in participants with Amyotrophic Lateral Sclerosis (ALS). This study will allow participants in the parent study to continue dosing. Enrolled participants will continue at the dose they received at the end of the first trial, and will self-administer SPG302 orally every day for up to 52 weeks. Participants will have an in-person clinic visit every 3 months (± 3 days) and a monthly phone visit. An end of treatment visit will occur within 7 days of the last dose of SPG302. A final visit to collect safety data will be conducted up to 1 month (± 3 days) post last dose.

C-SSRS (Columbia Suicide Severity Rating Scale)
Prospective suicidality assessment is performed using the Columbia-Suicide Severity Rating Scale (C-SSRS), a questionnaire to evaluate suicidal ideation and behavior. Answer "yes" on item 4 or 5 of the Suicidal Ideation section or "yes" on any item of the Suicidal Behavior section is considered positive. The suicidal behavior lethality sub-scale evaluates the level of actual or potential medical damage
Time frame: Up to 52 weeks
Change in the Amyotrophic Lateral Sclerosis Functional Rating Scale-revised (ALSFRS-R) scores
Questionnaire administered by a clinician that includes a series of questions about participants' ability to function in certain daily activities. Each type of function is scored from 4 (normal) to 0 (no ability), with a maximum total score of 48 and a minimum total score of 0. Patients with higher scores have more physical function. This outcome would evaluate these scores based on patient demographics including clinical presentation at outset of study, presence of ventilation assistance, and patient demographics. Results will be compared to matched historical controls
Time frame: up to 52 weeks
Change in Edinburgh Cognitive and Behavioural ALS Screen (ECAS)
The Edinburgh Cognitive and Behavioural ALS Screen (ECAS) assesses cognitive and behavioral changes in people with (ALS) through a 136-point test covering language, verbal fluency, executive function, memory, and visuospatial cognitive domains. A lower score indicates worsening of symptoms.
Time frame: up to 52 weeks
Changes from baseline in neurofilament light biomarker (NfL)

To assess the effect of SGP302 on NfL, a biomarker of neurodegeneration. A higher level of this biomarker indicates a progression of this disease.
Time frame: up to 52 weeks.
