A Study to Evaluate Safety and Pharmacokinetics of BIIB104 in Healthy Japanese and Non-Japanese Participants

Phase 1
Completed
Conditions
Healthy Volunteer
Interventions
Drug: Placebo
Registration Number
NCT05148481
Lead Sponsor
Biogen
Brief Summary

The primary objective of the study is to evaluate the pharmacokinetics (PK) of BIIB104 in healthy Japanese and non-Japanese participants. The secondary objective of the study is to evaluate the safety and tolerability of multiple, oral doses of BIIB104 administered twice daily (BID) for 9 days, with an additional dose occurring in the morning on Day 10 in healthy Japanese and non-Japanese participants.

Key

Exclusion Criteria
  • Participation in other studies involving treatment with an investigational drug within 30 days or 5 half-lives (whichever is longer) prior to randomization and/or during study participation.
  • History of severe allergic or anaphylactic reactions, systemic hypersensitivity reaction to BIIB104, or any allergic reactions that in the opinion of the investigator are likely to be exacerbated by any component of the study treatment.
  • History of seizures or a condition with risk of seizures.
  • History of, or positive test result at Screening for, human immunodeficiency virus (HIV).
  • Chronic, recurrent, or serious infection, as determined by the investigator, within 6 months prior to screening or between screening and Day 1.

Time to Reach Maximum Observed Concentration (Tmax) of BIIB104Up to Day 11
Maximum Observed Concentration (Cmax) of BIIB104Up to Day 11
Maximum Observed Concentration at Steady State (Cmax,ss) of BIIB104Up to Day 11
Time to Reach Maximum Observed Concentration at Steady State (Tmax,ss) of BIIB104Up to Day 11
Apparent Total Body Clearance (CL/F) of BIIB104Up to Day 11
Apparent Volume of Distribution (Vz/F) of BIIB104Up to Day 11
Accumulation Ratio for Steady State of BIIB104Up to Day 11

Accumulation ratio for steady state is defined as area under the concentration-time curve over a uniform dosing interval tau at steady state divided by area under the concentration-time curve within a dosing interval for single dose \[AUC(tau,ss)/AUC(tau,sd)\].

Area Under the Concentration-Time Curve Within a Dosing Interval for Single Dose [AUC(tau,sd)] of BIIB104Up to Day 11
Area Under the Concentration-Time Curve Over a Uniform Dosing Interval Tau at Steady State [AUC(tau,ss)] of BIIB104Up to Day 11
Elimination Half-Life (t½) of BIIB104Up to Day 11
Secondary Outcome Measures
NameTimeMethod
Number of Participants with Adverse Events (AEs)Day 1 up to Day 25

An adverse event (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, symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.

Number of Participants with Serious Adverse Events (SAEs)From screening up to Day 25

A serious adverse event (SAE) is any untoward medical occurrence that at any dose results in death, in the view of the investigator, places the participant at immediate risk of death (a life-threatening event), requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, results in a congenital anomaly/birth defect or is a medically important event.
