New treatment option for Chronic Lymphocytic Leukemia (CLL)
Official title Immune Profiling of CLL/SLL Treated With First-Line Pirtobrutinib
ClinicalTrials.gov ID: NCT07428707
What this study is testing
What is Pirtobrutinib?
Pirtobrutinib is an investigational medicine, given as an once-daily pill taken by mouth, being studied as a potential treatment for chronic lymphocytic leukemia (cll).
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- Background: Chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL) are blood cancers that affect certain white blood cells. Advanced forms of these diseases are difficult to treat.
- Phase 1: an early, usually small safety study
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
