ALSpire Trial Summary

This trial is testing a new drug for safety and how well it works in people with ALS or a related disease.

Who is the study for?
This trial is for adults with ALS, including those with a specific ATXN2 gene mutation. Participants must understand the study and give informed consent, have stable doses of certain ALS medications before starting, and meet criteria for diagnosing ALS. They need an informant/caregiver and should not have certain genetic mutations or history of substance abuse.Check my eligibility
What is being tested?
The ALSpire Study tests BIIB105's safety and effects on ALS progression over two parts: a 6-month phase where participants are randomly given either BIIB105 or placebo, followed by up to three years where all receive BIIB105. The study looks at how the body processes the drug and its impact on clinical function.See study design
What are the potential side effects?
Specific side effects aren't listed here but generally include reactions related to drug tolerance in organs, potential infusion-related issues, changes in blood parameters that will be closely monitored throughout the trial.

9Treatment groups
Experimental Treatment
Placebo Group
Group I: Part 2: Cohorts D1, D2: Open-LabelExperimental Treatment1 Intervention
Participants who complete Cohorts D1 and D2 will have a blinded Loading Dose Period, during which those who received placebo in Part 1 will receive BIIB105 Dose 4, IT, as 3 loading doses on Day 1 and two later days, while those who received BIIB105 in Part 1 will receive 2 loading doses of BIIB105 Dose 4, IT, on Days 1 and one later day, and placebo on Day 15. After the blinded Loading Dose Period, participants will receive BIIB105 Dose 4 up to thirty-eight maintenance doses, on up to thirty-eight later days.
Group II: Part 2: Cohorts A-C2: Open-LabelExperimental Treatment1 Intervention
Participants who complete Cohorts A, B, C1, and C2 will receive BIIB105 Dose 3, IT, as 3 loading doses on Day 1 and two later days, followed up to thirty-eight maintenance doses, on up to thirty-eight later days.
Group III: Part 1: Cohort D2Experimental Treatment1 Intervention
Participants with polyQ-ALS will receive BIIB105 Dose 4, IT, as 3 loading doses on Day 1 and two later days, followed by five maintenance doses on five later days.
Group IV: Part 1: Cohort D1Experimental Treatment1 Intervention
Participants with ALS will receive BIIB105 Dose 4, IT, as 3 loading doses on Day 1 and two later days, followed by five maintenance doses on five later days.
Group V: Part 1: Cohort C2Experimental Treatment1 Intervention
Participants with polyQ-ALS will receive BIIB105 Dose 3, IT, as 3 loading doses on Day 1 and two later days, followed by two maintenance doses on two later days.
Group VI: Part 1: Cohort C1Experimental Treatment1 Intervention
Participants with ALS will receive BIIB105 Dose 3, IT, as 3 loading doses on Day 1 and two later days, followed by two maintenance doses on two later days.
Group VII: Part 1: Cohort BExperimental Treatment1 Intervention
Participants with ALS will receive BIIB105 Dose 2, IT, as 3 loading doses on Day 1 and two later days, followed by two maintenance doses on two later days.
Group VIII: Part 1: Cohort AExperimental Treatment1 Intervention
Participants with ALS will receive BIIB105 Dose 1, intrathecally (IT), as 3 loading doses on Day 1 and two later days, followed by two maintenance doses on two later days.
Group IX: Part 1: Cohorts A-D2: PlaceboPlacebo Group1 Intervention
Participants with ALS and polyQ-ALS for Cohorts A, B, C1 and C2 will receive matching placebo to BIIB105 as 3 loading doses on Day 1 and two later days, followed by two maintenance doses on two later days, and participants with ALS and polyQ-ALS for Cohorts D1 and D2 will receive matching placebo to BIIB105 as 3 loading doses on Day 1 and two later days, followed by five maintenance doses on five later days.
