Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18-75 with histologically confirmed relapse refractory primary or secondary central nervous system lymphoma.

Probably not a fit

Patients who do not have relapse refractory central nervous system lymphoma or those with significant comorbidities may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial investigates the efficacy and safety of a combination regimen involving Selinexor, Methotrexate, and Rituximab in patients with relapse refractory primary and secondary central nervous system lymphoma. The study consists of a dose escalation phase followed by a phase 2 expansion, enrolling approximately 30 patients. Participants will receive escalating doses of Selinexor alongside standard treatments, with a total of six treatment cycles planned. The trial aims to assess the tolerability and effectiveness of this novel combination therapy.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with difficult-to-treat central nervous system lymphoma.

How similar studies have gone: While there have been studies on similar combination therapies, this specific approach with Selinexor is relatively novel and has not been extensively tested.
