How Chronic Lymphocytic Leukemia studies are organized in the registry

CLL is registered together with small lymphocytic lymphoma (SLL) in many records — they are treated as one disease in study design — so listings often carry both names. Drug-class abbreviations, particularly BTK and BCL-2 inhibitor terms, appear directly in current titles.

Terms that often appear in related listings
SLL BTK inhibitor relapsed CLL venetoclax

These describe how studies tend to be titled and grouped on ClinicalTrials.gov — they are search vocabulary, not medical guidance.
