A Safety, Tolerability, Pharmacokinetic, and Pharmacodynamic Study of BIIB091, a Bruton's Tyrosine Kinase (BTK) Inhibitor, in Healthy Adult Participants

A Phase 1, Randomized, Blinded, Placebo-Controlled, Single- and Multiple-Ascending Dose, Safety, Tolerability, Pharmacokinetic, and Pharmacodynamic Study of BIIB091, a Bruton's Tyrosine Kinase (BTK) Inhibitor, in Healthy Adult Participants

This study will evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of single and multiple oral doses of BIIB091 in healthy participants.This study will also determine the effect of food on the single oral dose pharmacokinetic (PK).

Study Overview

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Participants with Adverse Events (AEs) and Serious Adverse Events (SAEs)	An AE is any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An 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), however, this does not include an event that, had it occurred in a more severe form, might have caused death; 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.	Baseline up to Day 9 for SAD Cohorts; Baseline up to Day 24 for MAD Cohorts

Secondary Outcome Measures

Outcome Measure	Time Frame
Area Under the Curve from Time 0 to the Time of the Last Measurable Concentration (AUClast)	Baseline and multiple timepoints up to Day 3 for SAD Cohorts; Baseline and multiple timepoints up to Day 16 for MAD Cohorts
Area Under the Concentration-Time Curve From Time 0 Extrapolated to Infinity (AUCinf)	Baseline and multiple timepoints up to Day 3
Maximum Observed Concentration (Cmax)	Baseline and multiple timepoints up to Day 3 for SAD Cohorts; Baseline and multiple timepoints up to Day 14 for MAD Cohorts
Time to Reach Maximum Observed Concentration (Tmax)	Baseline and multiple timepoints up to Day 3 for SAD Cohorts; Baseline and multiple timepoints up to Day 14 for MAD Cohorts
