Follicular Lymphoma (FL/Indolent NHL) Aggressive NHL (a NHL) Chronic Lymphocytic Leukemia (CLL) / Small Lymphocytic Lymphoma (SLL) T-cell Lymphoma (PTCL and CTCL) B-cell Non Hodgkin Lymphoma (NHL) | Drug: Cerdulatinib (PRT062070) | Phase 1 Phase 2 |
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.

Experimental: cerdulatinib (PRT062070)
Intervention: Drug: cerdulatinib (PRT062070) or cerdulatinib (PRT062070) plus rituximab
|
Drug: Cerdulatinib (PRT062070) |
- Maximum tolerated dose (MTD) of cerdulatinib in patients with relapsed/refractory CLL/SLL or B-cell NHL. [ Time Frame: 28-day cycles until end of treatment ]
- Frequency and severity of dose limiting toxicity as classified by Common Terminology Criteria for Adverse Events (CTCAEv4) by dose level. (Phase 1) [ Time Frame: 28-day cycles until end of treatment ]Assessments: Antitumor activity of cerdulatinib as measured by ORR defined as CR+PR as measured by CT and CT/PET
- Assess antitumor activity of B-cell, T-cell NHL, or CLL/SLL, as a single agent and with rituximab for B-cell NHL (subtypes B-cell, T-cell NHL, or CLL/SLL) as single agent and with rituximab for B-cell NHL. [ Time Frame: 28-day cycles until end of treatment ]Assessments: Duration of response DOR, progression free survival PFS, time to treatment response TTR and lymph node response LNR, clinical benefit rate (CR+PR+SD)
- To further evaluate the PK profile of cerdulatinib in patients with specific subtypes of B-cell or T-cell NHL, alone or in combination with rituximab for B-cell NHL. [ Time Frame: 28-day cycles until end of treatment ]Assessments: (Cmax) and area under the plasma concentration versus time curve (AUC) of PRT602070.
- To further evaluate the PD of cerdulatinib in patients with specific subtypes of B-cell or T-cell NHL, alone or in combination with rituximab for B-cell NHL. [ Time Frame: 28-day cycles until end of treatment ]
- To assess tumor phenotype and genotype in relation to clinical response [ Time Frame: 28-day cycles until end of treatment ]
- To further evaluate the safety and tolerability of cerdulatinib in patients with specific subtypes of B-cell, T-cell NHL or CLL/SLL and the combination of cerdulatinib with rituximab in patients wtih B-cell NHL [ Time Frame: 28-day cycles until end of treatment ]Assessments: PE, vitals, laboratory values and AEs
- To evaluate the relationship between markers of inflammation with clinical outcome and overall health as determined by the Global Health Assessment. [ Time Frame: 28-day cycles until end of treatment ]
- To assess Minimal Residual Disease (MRD) status in CLL patients achieving a complete response/ complete response incomplete blood count recovery/partial response (CR/CRi/PR) by flow cytometry. [ Time Frame: 28-day cycles until end of treatment ]
