Ibrutinib and PD-1 Blockade in High Risk Lymphocytic Leukemia

Phase 2
Terminated
Conditions
Chronic Lymphocytic Leukemia
Interventions
Registration Number
NCT03514017
Lead Sponsor
H. Lee Moffitt Cancer Center and Research Institute
Brief Summary

The purpose of this study is to evaluate the impact of sequential overlapping treatment with PD-1 monoclonal antibody (mAb), pembrolizumab/MK-1375, followed by ibrutinib on endogenous immune function in previously untreated, high-risk CLL patients. Immune function will be evaluated through various laboratory correlative tests.

Pembrolizumab and IbrutinibIbrutinibTreatment with pembrolizumab and ibrutinib and follow-up period of up to 24 months. Pembrolizumab is a humanized monoclonal antibody that blocks the interaction between PD-1 and its ligands, PD-L1 and PD-L2. Ibrutinib is an inhibitor of Bruton's tyrosine kinase (BTK). Ibrutinib is a small-molecule inhibitor of BTK.

NameTimeMethod
Overall Response Rate (ORR) to the Therapeutic InterventionUp to 2 years

Response categories according to The International Workshop on Chronic Lymphocytic Leukemia (IWCLL): Complete remission (CR); Complete remission with incomplete marrow recovery (CRi); Partial remission (PR); Progressive disease (PD); Stable disease (SD), defined as not meeting criteria for CR, CRi, PR or PD.

Time to Best ResponseUp to 2 years

Time to best response to chronic lymphocytic leukemia (CLL) to the therapeutic intervention.

Secondary Outcome Measures
NameTimeMethod
Progression-free Survival (PFS)Up to 2 years

Progressive disease (PD), defined as ≥ 50% rise in lymphocyte count to \> 5 x10\^9/L, ≥ 50% increase in lymphadenopathy, ≥ 50% increase in liver or spleen size, Richter's transformation, or new cytopenias due to CLL.
