About this study
Official title: Efficacy and Safety of Chidamide in Combination With Lenalidomide and Rituximab (CR2) in Newly Diagnosed Elderly/unFit Double-Expressor DLBCL: A Prospective, Single-Arm, Multicenter Clinical Study
To evaluate the efficacy and safety of Chidamide in combination with lenalidomide and rituximab (CR2) as induction therapy, followed by chidamide maintenance in responding patients with newly diagnosed elderly/unfit double-expressor DLBCL.
- Being tested
- Chidamide in combination with Lenalidomide and Rituximab (CR2)
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Chidamide in combination with Lenalidomide and Rituximab (CR2)Drug
The treatment consists of induction therapy followed by maintenance therapy.
Induction Therapy: Chidamide + Lenalidomide + Rituximab.
Maintenance Therapy: Patients with ≥PR after 8 cycles receive: Chidamide+ Lenalidomide for 1 year (unless disease progression or intolerable toxicity occurs, whichever comes first).
Investigators may adjust drug doses/schedules based on individual tolerance.
| Study group | Role | What they receive |
|---|---|---|
| newly diagnosed elderly/unfit DE-DLBCL patients | Experimental | newly diagnosed elderly/unfit (Patients aged ≥70 years, or aged ≥60 years with comorbidities, or those with ECOG PS ≥2 deemed ineligible for standard chemotherapy) Double-Expressor Diffuse Large B-Cell Lymphoma patients Receives: Drug: Chidamide in combination with Lenalidomide and Rituximab (CR2) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Progression-Free Survival (PFS)
PFS is defined as the time from the first dose of study drug to the first documented disease progression, relapse, or death from any cause, whichever occurs first
Measured: From date of first dose until date of progression, relapse, or death from any cause, assessed up to 3 years.
Secondary outcomes (3)
Objective Response Rate (ORR)
Objective response is defined as complete response (CR) or partial response (PR) assessed according to Lugano 2014 criteria
Measured: Assessed at baseline and up to 8 cycles of chemotherapy (each cycle is 28 days), up to approximately 24 weeks
Overall Survival (OS)
OS is defined as the time from the first dose of study drug to death from any cause
Measured: From date of first dose until date of death from any cause, assessed up to 3 years
Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability]
Descriptive statistics were used to summarize investigational drug exposure, including treatment duration, number of administrations, and dose levels. Adverse events were graded according to NCI CTCAE version 5.0. Safety will be assessed throughout the treatment and follow-up periods
Measured: From first dose of study drug through 30 days after the last dose, assessed up to 3 years

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Chidamide in combination with Lenalidomide and Rituximab (CR2) in people with Double Expressor DLBCL and ELDERLY PEOPLE, run by The First Affiliated Hospital with Nanjing Medical University at 1 site in China.
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 7 inclusion and 15 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: looking for participants now, as of the sponsor's last update on 20 Oct 2026. 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 China. 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.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Lei Fan, Doctor (86-13813976136, fanlei3014@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Progression-Free Survival (PFS) (time frame: From date of first dose until date of progression, relapse, or death from any cause, assessed up to 3 years.). 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 20 Oct 2026; AzTrials last refreshed its copy on 26 Oct 2026.
