About this study

Official title: An Open-label Extension of SPG302-ALS-001 Study to Evaluate the Long-term Safety and Efficacy of Daily Oral SPG302 Treatment in Participants With Amyotrophic Lateral Sclerosis

This study will evaluate the long-term safety and efficacy of participants enrolled in SPG302-ALS-101 with Amyotrophic Lateral Sclerosis (ALS)

Read the detailed description

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Treatment emergent adverse events and serious adverse events

    Incidence, nature, and severity of treatment emergent adverse events (TEAEs) and serious adverse events (SAEs)

    Measured: Up to 52 weeks

  2. 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

    Measured: Up to 52 weeks

Secondary outcomes (3)
  1. 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

    Measured: up to 52 weeks

  2. 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.

    Measured: up to 52 weeks

  3. 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.

    Measured: up to 52 weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing SPG302 in people with Amyotrophic Lateral Sclerosis (ALS), run by Spinogenix at 3 sites in Australia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 17 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Australia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: patients treated through compassionate use program). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Treatment emergent adverse events and serious adverse events (time frame: Up to 52 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Dec 2025.
