- Incidence of Adverse Events (AEs) and Serious Adverse Events (SAEs) [ Time Frame: Screening (Day -28 ) up to Day 15 ]An AE is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. An SAE is any untoward medical occurrence that at any dose results in death, is a life-threatening event, requires inpatient hospitalization or prolongation of existing hospitalization, results in a significant disability/incapacity or congenital anomaly, or is a medically important event.
- Area Under the Concentration-Time Curve From Time 0 to Time of the Last Measurable Concentration (AUClast) of BIIB100 [ Time Frame: Day 1 (pre-dose) up to Day 3 ]BIIB100 will be measured in the plasma.
- Area Under the Concentration-Time Curve From Time 0 to Infinity (AUCinf) of BIIB100 [ Time Frame: Day 1 (pre-dose) up to Day 3 ]BIIB100 will be measured in the plasma.
- Maximum Observed Concentration (Cmax) of BIIB100 [ Time Frame: Day 1 (pre-dose) up to Day 3 ]BIIB100 will be measured in the plasma.
- Time to Reach Cmax (Tmax) of BIIB100 [ Time Frame: Day 1 (pre-dose) up to Day 3 ]BIIB100 will be measured in the plasma.
- Terminal Elimination Half-life (t1/2) of BIIB100 [ Time Frame: Day 1 (pre-dose) up to Day 3 ]BIIB100 will be measured in the plasma.
- Apparent Clearance (CL/F) of BIIB100 [ Time Frame: Day 1 (pre-dose) up to Day 3 ]BIIB100 will be measured in the plasma.
- Apparent Volume of Distribution During the Terminal Elimination (Vz/F) of BIIB100 [ Time Frame: Day 1 (pre-dose) up to Day 3 ]BIIB100 will be measured in the plasma.

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Key Inclusion Criteria:
- Must meet the laboratory-supported probable, probable, or definite criteria for diagnosing ALS according to the World Federation of Neurology El Escorial criteria.
- Participants taking concomitant riluzole at study entry must be on a stable dose for greater than or equals to (>=) 30 days prior to the first dose of study treatment (Day 1). Participants taking concomitant riluzole must be willing to continue with the same dose regimen throughout the study, unless the Investigator determines that riluzole should be discontinued for medical reasons, in which case it may not be restarted during the study.
- Participants taking concomitant edaravone at study entry must be on a stable dose for >= 60 days prior to the first dose of study treatment (Day 1).
- Adequate respiratory function as indicated by slow vital capacity (SVC) >= 65% of predicted value as adjusted for sex, age, and height (from the sitting position).
Key Exclusion Criteria:
- Ongoing medical condition (e.g., wasting or cachexia, severe anemia) that would, in the opinion of the Investigator, interfere with the conduct or assessments of the study.
- Significant cognitive impairment or unstable psychiatric illness, including psychosis, suicidal ideation, suicide attempt, or untreated major depression less than or equals to (<=) 90 days of Screening, which in the opinion of the Investigator would interfere with the study procedures.
- Treatment with drugs that are transported by Breast Cancer Resistance Protein (BCRP) and P-glycoprotein (P-gp) including, but not limited to, rosuvastatin, sulfasalazine, dabigatran, digoxin and fexofenadine.
- Current enrollment or plan to enroll in any interventional clinical study in which an investigational treatment or approved therapy for investigational use is administered within 30 days or 5 half-lives of the agent, whichever is longer, prior to the Baseline Visit (pre-dose on Day 1). Participation in a noninterventional study focused on ALS natural history may be allowed at the discretion of the Investigator and after consultation with the Sponsor.
Note: Other protocol defined Inclusion/Exclusion criteria may apply.
