Combination treatment for relapsed or refractory natural killer T-cell lymphoma

A Single-arm, Open-label, Phase II Study of Golidocitinib and Benmelstobart Combination Treatment in Patients with Relapsed or Refractory Extranodal Natural Killer/T Cell Lymphoma (ENKTL) (JACKPOT50)

Phase 2 Interventional Sun Yat-sen University · NCT06733051

This study is testing a new combination of two medications to see if they can help people with a type of lymphoma that hasn't responded to previous treatments.

What this trial studies

This clinical trial evaluates the safety and efficacy of a combination treatment using golidocitinib and benmelstobart in patients with relapsed or refractory extranodal natural killer/T cell lymphoma. It is a prospective, single-arm, multicenter phase II trial that aims to determine how well these medications work together in this specific patient population. Participants must have previously failed at least one line of asparaginase-based therapy and meet other eligibility criteria. The study will assess treatment outcomes based on measurable lesions and overall patient health.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with pathologically confirmed extranodal natural killer/T cell lymphoma who have experienced treatment failure with prior therapies.

Not a fit: Patients with invasive NK-cell leukemia, central nervous system involvement, or those who have previously been treated with JAK inhibitors may not benefit from this study.

Why it matters

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

How similar studies have performed: While this approach is novel in the context of this specific combination, similar studies have shown promise in treating other forms of lymphoma with targeted therapies.
