Study Arms:
- Phase 1 Cerdulatinib (Type: EXPERIMENTAL): During Phase 1, participants will receive oral cerdulatinib on Day 1 and then starting on Day 4 at doses of 15 mg up to 100 mg QD or oral cerdulatinib at doses of 15 mg up to 45 mg BID in 28-day cycles (except Cohort 1 will have a 21-day cycle starting on Day 1) for up to 10 cycles.
- Phase 2a Cerdulatinib (Type: EXPERIMENTAL): During Phase 2a, participants in cohorts based on cancer type will receive oral cerdulatinib at starting doses of 35, 30, or 20 mg BID on Day 1 in 28-day cycles for up to 10 cycles. Doses of cerdulatinib can be reduced to a minimum dose of 15 mg BID or increased to a maximum dose of 30 mg BID at the discretion of the Investigator based upon clinical judgment and with Sponsor Medical Monitor approval.
- Phase 2a Cerdulatinib plus Rituximab (Type: EXPERIMENTAL): During Phase 2a, participants in this cohort will receive oral cerdulatinib at their applicable dose and an IV injection of rituximab 375 mg/m\^2 on Days 1, 8, 15, and 22 of Cycle 1 and Day 1 of Cycles 4, 6, 8, and 10.

Based on this trial design, predict the completion outcome and termination type (if applicable).
