A Phase 1/2A Open-Label, Multi-Dose, Multi-Center Escalation and Exploratory Study of Cerdulatinib (PRT062070) in Patients With Relapsed/Refractory Chronic Lymphocytic Leukemia (CLL)/Small Lymphocytic Lymphoma (SLL) or B Cell or T Cell Non-Hodgkin Lymphoma (NHL)

This study will identify the highest dose, and assess the safety, of cerdulatinib (PRT062070)
that may be given in patients with relapsed/refractory chronic lymphocytic leukemia or
non-hodgkin lymphoma

This is an open-label, Phase 1/2a, multi dose, multi-center trial of orally administered
cerdulatinib assessing safety, tolerability and PK parameters conducted in 2 phases:

- Phase 1: Dose-escalation portion, during which 43 patients enrolled to receive a
single-agent cerdulatinib at their assigned dose level starting at 15 mg QD,
administered in increasing doses until the MTD/MAD is identified.

- Phase 2a: Consisting of 6 planned cohorts of up to 40 patients each by cancer type. Five
cohorts will receive single agent cerdulatinib at a starting dose of 30 mg BID for
28-day cycles. Cohort 2 receives cerdulatinib plus rituximab IV at 375 mg/m2.

Inclusion Criteria:

Phase 1 Specific Patient at least 18yrs of age with histologically confirmed CLL/SLL or
B-cell Non-Hodgkin lymphoma (DLBCL, FL, MCL, MZL, lymphoplasmacytic lymphoma).

Phase 2a Inclusion
