MEPL-G combination therapy for NK/T‑cell lymphoma with HLH

Combination of Mitoxantrone Liposome and Etoposide, Dexamethasone, Pegaspargase and Golidocitinib (MEPL-G) in the Treatment of NK/T-cell Lymphoma Associated Hemophagocytic Lymphohistiocytosis (NKTCL-HLH): a Prospective, Multi-center, Single Arm, Phase Ib/II Clinical Trial

Phase1; Phase2 Interventional Beijing Tongren Hospital · NCT07525466

This trial will test whether the MEPL-G drug combination (liposomal mitoxantrone, etoposide, pegaspargase, methylprednisolone, and golidocitinib) can control both the lymphoma and the life‑threatening HLH inflammation in adults with NK/T‑cell lymphoma–associated HLH.

What this trial studies

This is a phase 1/2, open‑label trial combining a selective JAK1 inhibitor (golidocitinib) with liposomal mitoxantrone and established HLH-directed agents (etoposide, pegaspargase, methylprednisolone) to treat adults with extranodal NK/T‑cell lymphoma complicated by HLH. The approach pairs targeted inhibition of JAK/STAT‑driven inflammation with cytotoxic and anti‑HLH agents to try to control both tumor burden and cytokine storm. Primary objectives include safety, tolerability, dose finding and preliminary efficacy endpoints such as response rate and short‑term survival. Patients receive treatment at Beijing Tongren Hospital with close monitoring of cardiac function, infections, and viral hepatitis markers.

Who should consider this trial

Good fit: Adults (≥18) with histologically confirmed extranodal NK/T‑cell lymphoma who meet HLH‑2004 diagnostic criteria and who meet cardiac, infection, and viral hepatitis safety requirements are the intended candidates.

Not a fit: Patients with significant cardiac dysfunction (NYHA ≥ II or LVEF <50%), uncontrolled infections, pregnancy or breastfeeding, or certain concurrent malignancies are unlikely to benefit or are excluded.

Why it matters

Potential benefit: If successful, this regimen could rapidly control both the lymphoma and the fatal HLH cytokine storm, improving short‑term survival and enabling patients to reach longer‑term therapies.

How similar studies have performed: Components such as golidocitinib and pegaspargase have shown anti‑NKTCL or anti‑HLH activity in preclinical or early clinical work, but the full MEPL‑G combination is novel and not yet validated in large trials.
