ZG005 with gecacitinib for relapsed or refractory lymphoma

A Multicenter, Open-Label, Dose-Escalation and Dose-Expansion Phase I/II Study of ZG005 in Combination With Gecacitinib in Patients With Relapsed or Refractory Lymphoma

PHASE1; PHASE2 · Suzhou Zelgen Biopharmaceuticals Co.,Ltd · NCT06883526

We are testing whether ZG005 given with gecacitinib is safe and helps adults whose lymphoma has come back or hasn't responded to prior treatments.

What this trial studies

This Phase 1/2 interventional trial enrolls adults with histologically confirmed relapsed or refractory lymphoma to receive ZG005 injections plus oral gecacitinib. Part 1 (Phase 1) will explore safety and tolerability and determine the recommended Phase 2 dosing regimen for the combination. Part 2 (Phase 2) will then test the combination's efficacy in the same patient population using the dose selected from Part 1. Key exclusions include known CNS lymphoma and severe cardiovascular or cerebrovascular disease, and the trial is conducted at The First Affiliated Hospital, Zhejiang University School of Medicine under Suzhou Zelgen Biopharmaceuticals sponsorship.

Who should consider this trial

Good fit: Adults (≥18) with histologically confirmed relapsed or refractory lymphoma who can consent and do not have CNS involvement or serious cardiovascular/cerebrovascular disease are the intended participants.

Not a fit: Patients with known CNS involvement, severe heart or stroke-related conditions, or other investigator-determined reasons are unlikely to be eligible or to benefit from participation.

Why it matters

Potential benefit: If successful, this combination could offer a new treatment option that controls disease in some patients with relapsed or refractory lymphoma.

How similar studies have performed: Combining targeted biologic agents with oral kinase inhibitors has shown activity in certain lymphomas, but the specific ZG005 plus gecacitinib combination is investigational with limited public data to date.
