NB02(POSELTINIB) Monotherapy in R/R Non-Hodgkin's Lymphoma (POTENTIAL-M)

January 28, 2026 updated by: NOBO Medicine

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

This trial is an open-label, multicenter, monotherapy, dose-escalation, phase 1 clinical trial to evaluate the safety, tolerability, pharmacokinetics (PK), and preliminary anti-tumor activity of NB02 (posseltinib) in patients with relapsed/refractory NHL including FL, MCL and MZL

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study will conduct dose-finding. The dose-finding will be set as 3+3 design to seek candidates for optimal doses. Patients will receive study drugs to determine the MTD and/or OBD. In this study, OBD is defined as the most reasonable dose considering the benefit/risk ratio from available non-clinical and clinical data. The OBD will be determined based on available safety, PK/PD, and preliminary efficacy data, with a focus on identifying the dose that optimally balances clinical activity and tolerability.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Age 19 to 80 years.
  2. Patients must voluntarily agree to participate in the study and provide written informed consent prior to any study-related procedures.
  3. Patients with histologically confirmed follicular lymphoma, mantle cell lymphoma or marginal zone lymphoma.
  4. relapsed/refractory Patients who have received more than two prior lines of therapy.
  5. Measurable disease based on Lugano classification.
