NCT03514017

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.

Outcome Measures

Primary Outcomes (2)

  • Overall Response Rate (ORR) to the Therapeutic Intervention

    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.

    Up to 2 years

  • Time to Best Response

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

    Up to 2 years

Secondary Outcomes (1)

  • Progression-free Survival (PFS)

    Up to 2 years

Study Arms (1)

Pembrolizumab and Ibrutinib

EXPERIMENTAL

Treatment 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.

Drug: PembrolizumabDrug: Ibrutinib

Interventions

Pembrolizumab will be administered intravenously (IV) at 200 mg every 3 weeks for 1 year and up to 2 years.

Also known as: Keytruda®
Pembrolizumab and Ibrutinib

Ibrutinib will be administered orally once daily at approximately the same time each day at the dose of 420 mg daily (3 capsules of 140 mg daily).

Also known as: Imbruvica®
Pembrolizumab and Ibrutinib
