About this study
Official title: Clonal Evolution of B Cells in High-risk Chronic Lymphocytic Leukemia Patients After Idelalisib-rituximab Treatment
The purpose of the study is to assess the evolution of B cells at a genetic and surface-marker level in high-risk CLL after idelalisib-rituximab treatment. The targeted population includes 20 subjects ages 18 or older diagnosed with high-risk CLL. This will include patients with relapsed or refractory disease who require therapy with idelalisib and rituximab as per FDA label. This is an observational study for peripheral blood samples of these patients collected at pre-determined time points.

Questions about this trial
What is this clinical trial studying?
An observational study of Chronic Lymphocytic Leukemia, run by Abramson Cancer Center at Penn Medicine at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 10 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: withdrawn, as of the sponsor's last update on 16 Apr 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was withdrawn before enrolling participants, so there are no results.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of somatic hypermutation (time frame: 12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Apr 2019; AzTrials last refreshed its copy on 6 Nov 2026.
