Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Pembrolizumab and Ibrutinib

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.

Group Type EXPERIMENTAL

Pembrolizumab

Intervention Type DRUG

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

Ibrutinib

Intervention Type DRUG

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).
