Item 8.01. Other Events.

The Company is providing the following preliminary results for the ongoing vecabrutinib clinical trial. Two of the three chronic lymphocytic leukemia (“CLL”) patients in Cohort 6 (400mg twice daily) had stable disease upon first response assessments including a patient with a 48% reduction in tumor burden. One patient was determined to have progressive disease but will remain on study as the investigator has determined that the patient is receiving benefit. All three patients remain on study and are in cycle 5. The status of patients being treated in Cohort 7 (500mg twice daily) is also being updated. Three CLL patients and two mantle cell lymphoma patients remain on study at the 500 mg dose level. Additional patients continue to be evaluated for this cohort, and the Company is on track to announce first response assessments for Cohort 7 in the second quarter.

These are preliminary data from an ongoing clinical trial and should be considered with caution and not relied upon as indicative of future clinical results.
