Relapsed/Refractory B-cell Malignancies

Brief summary

The primary objective of this study is to determine the long-term safety and tolerability of tirabrutinib in adults with relapsed/refractory B-cell malignancy who have tolerated and achieved stable disease or improved with tirabrutinib treatment while enrolled in a prior (parent study) tirabrutinib study (NCT01659255). The dosing regimen will be based on the prior dosing regimen from the parent study.

Percentage of Participants Who Experienced Treatment-Emergent Marked Laboratory AbnormalitiesFirst dose of tirabrutinib up to 36 months in the parent study and up to 61 months in the rollover studyTreatment-emergent marked laboratory abnormalities were defined as values that increase from baseline by at least 3 toxicity grades at any postbaseline time point, up to and including the date of the last dose of study drug plus 30. If the relevant baseline laboratory value is missing, any Grade 3 or 4 values observed within the timeframe specified above will be considered treatment-emergent marked abnormalities. Laboratory assessments included tests for Chemistry, Hematology, Coagulation and Urinalysis.

Recruitment details

Participants were enrolled at study sites in the United Kingdom and France. The first participant was screened on 10 September 2015. The last study visit occurred on 30 December 2020.

Pre-assignment details

102 participants were screened. Participants must have been enrolled in parent study ONO-4059POE001 (NCT01659255) to be eligible to receive continued access to tirabrutinib in this rollover study.

Percentage of Participants Who Experienced Treatment-Emergent Adverse Events (AEs)

Treatment-emergent AEs were defined as one or both of the following: * Any AEs with an onset date on or after the study drug start date of parent study and no later than 30 days after permanent discontinuation of study drug in this rollover study; * Any AEs leading to premature discontinuation of study drug.

Time frame: First dose of tirabrutinib up to 36 months in the parent study and up to 61 months in the rollover study

Population: Safety Analysis Set included all participants who took at least 1 dose of study drug in the study. The data for this study are summarized by integrating the parent (NCT01659255) study data and rollover study data. One participant in 600 mg arm (CLL), received 40 mg dose for a longer period of time in parent study. Hence, this participant was included in 40 mg arm in safety analysis set.
