Purinostat mesylate injections versus oral selinexor for relapsed or refractory diffuse large B‑cell lymphoma
Official title: A Randomized, Controlled, Multicenter Phase III Clinical Study Evaluating the Efficacy and Safety of the Purinostat Mesylate for Injection (PM) Compared to Selinexor in Patients With Relapsed/Refractory Diffuse Large B-cell Lymphoma (R/R DLBCL)
Run by Chengdu Zenitar Biomedical Technology Co., Ltd · NCT07011056 · Data updated 2026-11-12
This study tests whether purinostat mesylate injections work better than oral selinexor for adults with relapsed or refractory diffuse large B‑cell lymphoma.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18 or older with histologically confirmed relapsed or refractory DLBCL after at least two prior systemic therapies, measurable disease, ECOG performance status ≤2, and adequate organ function are appropriate candidates.
✕Probably not a fit
Patients with double/triple‑hit B‑cell lymphoma, prior transplantation, active or reactivated infections, pregnancy or breastfeeding, or other serious illnesses that make participation unsafe are unlikely to benefit from this protocol.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Adults with relapsed or refractory diffuse large B‑cell lymphoma who have received at least two prior systemic therapies are enrolled and assigned to receive one of two treatments. The experimental arm receives purinostat mesylate intravenously (11.2 mg/m2 on days 1, 4, 8 and 11 of a 21‑day cycle) for up to six cycles, while the control arm receives oral selinexor 60 mg twice weekly in 4‑week cycles. The main outcomes are objective response rate and overall survival as determined by a blinded independent central review (BICR). Safety and tolerability are monitored throughout treatment.
Why it matters
Potential benefit: If successful, this treatment could provide higher response rates and longer survival than current selinexor therapy for people with relapsed or refractory DLBCL.
How similar studies have gone: Selinexor has shown activity in relapsed/refractory DLBCL in prior studies, while purinostat mesylate has more limited early‑phase data and this Phase III comparison aims to clarify its benefit.
