Summary

Extranodal NK/T-cell lymphoma (NKTCL) is an aggressive EBV-associated lymphoma with poor prognosis, highly prevalent in China. Early-stage NKTCL achieves favorable long-term survival, while advanced disease shows dismal outcomes with no standard therapy. Notably, 10%-20% of patients develop secondary hemophagocytic lymphohistiocytosis (NKTCL-HLH), a life-threatening complication with median survival \<2 months and mortality over 90%. Current treatments fail to simultaneously control lymphoma and hyperinflammation, with poor tolerance and high resistance. The JAK/STAT pathway drives EBV-induced inflammation and tumor progression. Golidocitinib, a selective JAK1 inhibitor, demonstrates potent anti-NKTCL activity and rapid inflammation control. Liposomal mitoxantrone offers targeted efficacy with lower toxicity, while etoposide, methylprednisolone, and pegaspargase provide synergistic anti-tumor and anti-HLH effects. This study proposes the novel MEPL-G regimen (liposomal mitoxantrone, etoposide, methylprednisolone, pegaspargase, golidocitinib) for NKTCL-HLH. By targeting both HLH and NKTCL, this combination aims to achieve rapid disease control, improve tolerance, and prolong survival, addressing the unmet critical clinical need for this high-risk population.

Detailed description

Extranodal NK/T-cell lymphoma (NKTCL) is an aggressive Epstein-Barr virus (EBV)-associated non-Hodgkin lymphoma with particularly high incidence in Asia, especially in southern China where it accounts for 10%-15% of all malignant lymphomas. Early-stage NKTCL can achieve an 80% long-term survival rate with radiotherapy combined with pegaspargase-based chemotherapy. However, advanced and relapsed/refractory NKTCL carries a dismal prognosis, with long-term survival below 40%. A severe complication is hemophagocytic lymphohistiocytosis (HLH), which develops in 10%-20% of patients and leads to an extremely aggressive clinical course, with median survival less than 2 months and 6-month overall survival of only 23%. Pathogenically, EBV infection induces abnormal immune activation through the JAK/STAT and NF-κB pathways, triggering a cytokine storm characterized by elevated IFN-γ, TNF-α, IL-6, and IL-10. This immune dysregulation, combined with impaired cytotoxic function, drives both lymphomagenesis and HLH progression. Current treatments remain unsatisfactory. Traditional HLH-directed regimens fail to control underlying lymphoma, while conventional lymphoma chemotherapy shows limited efficacy and poor tolerance due to multi-drug resistance and organ dysfunction. Recently, targeted agents have emerged as promising strategies. Golidocitinib, a highly selective JAK1 inhibitor, effectively blocks JAK1-STAT3 signaling, suppresses EBV-driven tumor growth, and mitigates cytokine storms. It has demonstrated encouraging anti-tumor activity in relapsed/refractory NKTCL. Meanwhile, liposomal mitoxantrone improves tumor targeting and reduces cardiotoxicity, with objective response rates of 50%-60% in NKTCL. Etoposide, methylprednisolone, and pegaspargase further provide synergistic anti-lymphoma and anti-inflammatory effects. Our research group has accumulated extensive experience in NKTCL and NKTCL-HLH, validating effective combination regimens and supporting the rationale of combining anti-lymphoma and anti-HLH strategies. Therefore, this study designed the innovative MEPL-G regimen (liposomal mitoxantrone, etoposide, methylprednisolone, pegaspargase, golidocitinib) for NKTCL-HLH patients. This regimen aims to rapidly control HLH, eradicate lymphoma, improve safety and tolerance, and ultimately prolong survival, addressing the urgent unmet medical need for this high-risk population.

Type	Name	Description
DRUG	Mitoxantrone liposome	In the Phase Ib part, 3 patients will be enrolled at the starting dose of liposomal mitoxantrone: 18 mg/m²/d on day 1, every 3 weeks (q3w). If no DLT occurs, the recommended phase 2 dose (RP2D) will be 18 mg/m²/d on day 1 q3w. If DLT occurs, the dose will be de-escalated sequentially (18→16→14→12 mg/m²/d on day 1 q3w).
