Trial Outcomes & Findings for A Study to Evaluate Pirtobrutinib (LOXO-305) in Healthy Adult Participants (NCT NCT06181006)

NCT ID: NCT06181006

Last Updated: 2025-01-14

Results Overview

TEAE is defined as an adverse event (AE) which starts on or after the first administration of study drug. A serious adverse event is defined as any AE occurring at any dose that results in any of the following outcomes: death; a life-threatening adverse drug experience; inpatient hospitalization or prolongation of existing hospitalization; a persistent or significant disability/incapacity; a congenital anomaly/birth defect; an important medical event that may require medical or surgical intervention to prevent any of the above outcomes.
