Experimental Treatment
Group I: Mavorixafor and IbrutinibExperimental Treatment2 Interventions
Each participants will initially receive mavorixafor at Dose Level 1 (200 mg QD) in combination with ibrutinib 420 mg. Cohort A will comprise the first 6 participants enrolled in the study that complete at least their first cycle at Dose Level 2 (400 mg QD). Cohort A participants will start at Dose Level 1 and be allowed to dose escalate after the first cycle to Dose Level 2, if no DLTs are observed during the first cycle of each participant. Cohort B will comprise the next 6 participants enrolled into the study that complete at least their 1st cycle at Dose Level 3 (600 mg QD). Cohort B participants will start at Dose Level 1 and be allowed to dose escalate up to Dose Levels 2 and 3. Cohort C will comprise the remainder of participants enrolled up to the total of 18. Cohort C participants will start at Dose Level 1 and be allowed to escalate to 400 and 600 mg after each dose level has been deemed safe by participants from Cohort A and B.
