Phase I Study of Cosibelimab and Balixafortide in Metastatic Pancreatic Ductal Adenocarcinoma

This is a single-center, open-label, phase 1 dose escalation and dose expansion (safety confirmation) trial to evaluate the safety and tolerability of balixafortide and cosibelimab in patients with metastatic PDAC who progressed after SOC chemotherapy. In the dose escalation cohort, a maximum of 12 patients will be enrolled exploring three dose levels of balixafortide to identify the maximum tolerated dose (MTD) and recommended phase II dose (RP2D). Dosing of cosibelimab will remain constant (800 mg IV). Cosibelimab will be given IV every 2 weeks and balixafortide will be given IV weekly at the assigned dose, until disease progression or unacceptable toxicity for up to 2 years.
