ARC-02 with Rituximab for B-cell non-Hodgkin lymphomas
Official title: A Study to Evaluate Safety, Tolerability, Pharmacokinetics (PK), and Clinical Activity of ARC-02 in Adult Participants With B-cell Non-Hodgkins Lymphoma (NHL)
Run by Taiho Oncology, Inc. · NCT07691606 · Data updated 2026-11-12
This study tests ARC-02, together with Rituximab, to see if the treatment is safe and shows early signs of activity in people with B-cell non-Hodgkin lymphomas who have already tried multiple therapies.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults with measurable B-cell NHL (including FL, MZL, MCL, DLBCL, or other B-cell subtypes) who have had at least two prior systemic therapies and are not eligible for additional standard treatments.
✕Probably not a fit
Patients with non-measurable disease, poor organ function, significant neuropathy, active participation in another trial, or those not meeting key eligibility criteria may have limited or no benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This Phase 1 trial evaluates ARC-02 in combination with Rituximab for patients with various B-cell non-Hodgkin lymphomas who have exhausted standard options. It will examine safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy. Eligibility requires measurable disease, multiple prior therapies, and adequate organ function. The study is conducted at select U.S. sites including California, Kentucky, and North Carolina. Primary goals focus on safety and dosing, with secondary signals of activity guiding future development.
Why it matters
Potential benefit: If successful, ARC-02 plus Rituximab could offer a new therapeutic option and potential disease control for patients with relapsed or refractory B-cell NHL.
How similar studies have gone: Some early-phase studies in B-cell NHL using novel agents in combination regimens have shown safety signals and hints of activity, but this exact ARC-02 plus Rituximab approach remains exploratory.
