MR001 plus chemotherapy for advanced or metastatic pancreatic ductal adenocarcinoma after first-line therapy

An Open-label, Dose-escalation and Dose-expansion Phase Ib/IIa Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Efficacy of MR001 in Combination With Standard Chemotherapy Regimens in Patients With Locally Advanced or Metastatic Pancreatic Ductal Adenocarcinoma (PDAC) Who Have Progressed After First-line Therapy

Phase1; Phase2 Interventional Shenzhen Majory Biotechnology Co., Ltd. · NCT07235202

This trial will test whether adding MR001 to standard chemotherapy helps people with locally advanced or metastatic pancreatic ductal adenocarcinoma whose disease progressed after first-line therapy.

What this trial studies

This open-label Phase Ib/IIa study uses a dose-escalation followed by dose-expansion design to test the safety, tolerability, pharmacokinetics, and preliminary efficacy of MR001 given with standard chemotherapy in patients with locally advanced or metastatic PDAC who progressed after one prior systemic regimen. MR001, a monoclonal antibody directed at pathways related to CD4/TGF-β1 signaling, is administered in combination with standard regimens including irinotecan liposome plus 5-FU/LV, nab-paclitaxel, or gemcitabine. Primary endpoints focus on safety, tolerability, and pharmacokinetics during dose escalation, with expansion cohorts assessing preliminary anti-tumor activity by RECIST v1.1 and exploratory biomarker analyses. The trial is sponsored by Shenzhen Majory Biotechnology and conducted at Beijing Tsinghua Changgung Hospital.

Who should consider this trial

Good fit: Adults with histologically confirmed locally advanced or metastatic PDAC who progressed after exactly one prior systemic therapy, have ECOG 0–1, measurable disease, and adequate organ function would be eligible.

Not a fit: Patients with uncontrolled brain metastases, significant organ dysfunction, recent systemic immunosuppression, pregnancy, or known hypersensitivity to MR001 are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, adding MR001 could improve disease control and survival for patients with PDAC who have limited options after first-line therapy.

How similar studies have performed: Combining immunomodulatory antibodies with chemotherapy in PDAC is relatively novel and while preclinical data and limited early-phase clinical work suggest potential, there is not yet established proof of major clinical benefit in this setting.
