Using low-dose Decitabine with COP chemotherapy for relapsed DLBCL

A Prospective Study of Low-dose Decitabine Combined With COP Regimen in the Treatment of Relapsed and Refractory DLBCL

Observational First Affiliated Hospital of Harbin Medical University · NCT03494296

This study is testing if adding a low dose of Decitabine to standard chemotherapy can help people with relapsed diffuse large B-cell lymphoma who haven't responded to other treatments.

What this trial studies

This study investigates the combination of low-dose Decitabine and the COP chemotherapy regimen in patients with relapsed and refractory diffuse large B-cell lymphoma (DLBCL). Decitabine acts as a DNA methyltransferase inhibitor, aiming to reverse DNA methylation and promote tumor cell differentiation or apoptosis. The study focuses on patients who have not responded to standard treatments and evaluates the effectiveness of this novel combination therapy. Participants will receive the D-COP regimen, which includes Decitabine alongside traditional chemotherapy agents.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with histopathologically confirmed relapsed or refractory DLBCL.

Not a fit: Patients with severe organ dysfunction, active infections, or significant heart disease may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve treatment outcomes and survival rates for patients with relapsed DLBCL.

How similar studies have performed: While the use of Decitabine in combination therapies is promising, this specific approach has not been extensively tested in prior studies.
