Clinical trial Recruiting at 6 sites Phase 1 Interventional Ages 19 to 80

Poseltinib (NB02) alone for relapsed or refractory non-Hodgkin lymphoma

Official title: An Open-Label, Multicenter, Monotherapy, Dose-Escalation, Phase 1 Clinical Trial of NB02 (Posseltinib) in Patients With Relapsed/Refractory Non-Hodgkin's Lymphoma

Run by NOBO Medicine · NCT07114367 · Data updated 2026-11-12

This trial tests oral poseltinib (NB02) to see if it is safe and shows anti-lymphoma activity in adults 19–80 with relapsed or refractory follicular, mantle cell, or marginal zone lymphoma after at least two prior treatments.

Is this trial a fit for you?

Likely a good fit

Adults aged 19–80 with confirmed follicular, mantle cell, or marginal zone lymphoma who have relapsed or are refractory after more than two prior therapies, have measurable disease, ECOG ≤2, and can take oral medication are the intended participants.

Probably not a fit

Patients previously treated with poseltinib, those who cannot take oral medications, those unable to comply with study procedures, and most patients who progressed on BTK inhibitor regimens (except those who stopped BTKi due to intolerance or nonmedical reasons) are unlikely to be eligible or to benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This open-label, multicenter phase 1 dose-escalation trial gives poseltinib as monotherapy to patients with relapsed or refractory non-Hodgkin lymphomas (including FL, MCL, and MZL) to characterize safety, tolerability, pharmacokinetics, and preliminary anti-tumor activity. A standard 3+3 design will be used to identify the maximum tolerated dose (MTD) and/or the optimal biologic dose (OBD) based on safety, PK/PD, and early efficacy signals. Eligible participants are adults 19–80 with histologically confirmed disease, measurable lesions per Lugano, ECOG ≤2, and more than two prior lines of therapy; prior poseltinib exposure is excluded. The trial is conducted at several university hospitals in South Korea and will collect safety data, pharmacokinetic samples, and tumor response assessments.

Why it matters

Potential benefit: If poseltinib proves safe and active, it could become a new oral treatment option for patients with relapsed or refractory indolent and mantle cell lymphomas.

How similar studies have gone: Other BTK inhibitors have demonstrated activity in mantle cell and marginal zone lymphoma and some benefit in relapsed indolent lymphomas, but poseltinib itself remains at an early clinical stage.
