A Phase 2 interventional study of Epcoritamab in CLL, CLL (Chronic Lymphocytic Leukemia) and Chronic Lymphocytic Leukemia (CLL), sponsored by University of California, Irvine. Not yet recruiting at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-11-09.
Sponsored by University of California, Irvine · Phase 2, Interventional, and Treatment
This is a phase 2, single-arm, open-label clinical trial determining efficacy of Epcoritamab in subjects with Chronic Lymphocytic Leukemia (CLL) on Burton Tyrosine Kinase Inhibitor (BTKi).
2,036 studies on the registry are indexed under Leukemia, Lymphocytic, Chronic, B-Cell; 237 are open to participants now.
This study's planned enrollment of 24 is below the median of 39 across 1,603 interventional studies indexed under Leukemia, Lymphocytic, Chronic, B-Cell.
Browse Leukemia, Lymphocytic, Chronic, B-Cell studies →University of California, Irvine is the lead sponsor of 476 studies on the registry; 98 are open to participants now.
Of its 41 completed or terminated interventional studies of FDA-regulated products, 30 (73%) have results posted.
Compared within Leukemia, Lymphocytic, Chronic, B-Cell, this study's primary condition as ClinicalTrials.gg classifies it; the registry's first condition term is Leukemia, B-Cell. The counts are of registry records indexed under each term, refreshed daily. How we classify →

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.
“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Start is estimated for Dec 2026; primary completion for Oct 2028, 22 months later.
Of 208 non-industry phase 2 interventional studies under Leukemia, Lymphocytic, Chronic, B-Cell, half reached primary completion within 75 months of starting (the median), counting those still running; a quarter within 42 and three quarters within 119. This study's planned 22 months is below that.
Counting every sponsor, half of 249 studies reached it within 73 months; a quarter within 41 and three quarters within 114.
Start moved once since we started tracking on Sep 25, 2026: Oct 2026 → Dec 2026, on Nov 9, 2026.
