Trial Outcomes & Findings for DDI Study of Evobrutinib and Carbamazepine (NCT NCT05248945)

NCT ID: NCT05248945

Last Updated: 2026-01-15

Results Overview

AUC0-inf was calculated by combining AUC0-t and AUCextra. AUCextra represents an extrapolated value obtained by Clast pred/Lambda z, where Clast pred was the calculated plasma concentration at the last sampling time point at which the measured plasma concentration is at or above the Lower Limit of quantification (LLQ) and Lambda z was the apparent terminal rate constant determined by log-linear regression analysis of the measured plasma concentrations of the terminal log-linear phase.

PRIMARY outcome

Timeframe: Evobrutinib: Predose and 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8,12,16 and 24 hours post dose on Day 1 and Day 19.

Population: The Pharmacokinetic Analysis Set included all participants who had completed the study without any relevant protocol deviations and factors likely to affect the comparability of PK results. Here 'Overall number of participants analyzed' = number of participants evaluable for this outcome measure.

AUC0-inf was calculated by combining AUC0-t and AUCextra. AUCextra represents an extrapolated value obtained by Clast pred/Lambda z, where Clast pred was the calculated plasma concentration at the last sampling time point at which the measured plasma concentration is at or above the Lower Limit of quantification (LLQ) and Lambda z was the apparent terminal rate constant determined by log-linear regression analysis of the measured plasma concentrations of the terminal log-linear phase.

Timeframe: Baseline (Day 1) and Day 26

Population: The safety analysis set included all participants, who were administered any dose of any study intervention.

An adverse event (AE) was defined as any untoward medical occurrence in a participant. An AE was any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with use of a study intervention. A serious adverse event (SAE) was any untoward medical occurrence that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect or was otherwise considered medically important. TEAE's were those events with onset dates on or after the first administration of study intervention. TEAEs include both Serious TEAEs and non-serious TEAEs."

Timeframe: Baseline (Day 1) and Day 26

Population: The safety analysis set included all participants, who were administered any dose of any study intervention.

Blood samples were collected to analyze the hematology parameters: Platelets, Leukocytes, Neutrophils, Eosinophils, Basophils, Monocytes, and Lymphocytes Values. Baseline was the last scheduled measurement before administration of study intervention. Absolute changes from baseline was calculated by subtracting the post-dose visit value from the Baseline value.

AE was defined as any untoward medical occurrence in a subject. An AE was any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with use of a study intervention. SAE was any untoward medical occurrence that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect or was otherwise considered medically important. TEAE's were those events with onset dates on or after the first administration of study intervention. TEAEs include both Serious TEAEs and non-serious TEAEs. Severity of AE were assessed by the investigator as Mild, Moderate, and Severe: An event that prevents normal everyday activities. Severe is a category used to rate the intensity of an event; both AEs and SAEs can be assessed as severe. SAS is used.
