Combination treatment of sintilimab and linperlisib for relapsed NK/T-cell lymphoma

Open-Label, Phase Ib Study of Sintilimab and Linperlisib Combination Treatment in Patients with Relapsed or Refractory Extranodal Natural Killer/T Cell Lymphoma (NKTCL)

Phase 1 Interventional Sun Yat-sen University · NCT06793956

This study is testing a new combination of two drugs, sintilimab and linperlisib, to see if it can help people with relapsed NK/T-cell lymphoma who haven't had success with other treatments.

What this trial studies

This open-label, phase Ib study evaluates the effectiveness of combining sintilimab and linperlisib in patients with relapsed or refractory extranodal natural killer/T-cell lymphoma (NKTCL). The trial aims to determine the safety and efficacy of this combination treatment in individuals who have not responded to previous therapies. Participants must have a confirmed diagnosis of NKTCL and meet specific eligibility criteria, including having measurable lesions and adequate organ function. The study is designed to provide insights into a potential new treatment option for this challenging condition.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with pathologically confirmed relapsed or refractory NKTCL after prior treatment failure.

Not a fit: Patients with a history of aggressive NK-cell leukemia or those who have previously been treated with PI3K inhibitors may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could offer a new therapeutic option for patients with relapsed or refractory NKTCL.

How similar studies have performed: While this approach is novel in the context of NKTCL, similar combination therapies have shown promise in other hematological malignancies.
