Study of HuMab-5B1 (MVT-5873) in Subjects With Pancreatic Cancer or Other Cancer Antigen 19-9 (CA19-9) Positive Malignancies

Phase 1 Safety and Tolerability Study of Human Monoclonal Antibody 5B1 (MVT-5873) With Expansion in Subjects With Pancreatic Cancer or Other CA19-9 Positive Malignancies

Phase 1 Safety and Tolerability Study in Subjects with Pancreatic Cancer or Other CA19-9 Positive Malignancies.

Study Overview

• Status: Terminated
• Conditions: Pancreatic Cancer
• Intervention / Treatment: Drug: MVT-5873; Drug: modified FOLFIRINOX (mFOLFIRINOX); Drug: gemcitabine + nab-paclitaxel

Detailed Description

Open label, multicenter, non-randomized, dose escalation/expansion trial of MVT-5873 as a single agent and in combination with standard of care chemotherapy or modified FOLFIRINOX (mFOLFIRINOX) in subjects with pancreatic and other CA19-9 positive malignancies. The study was designed to define a Maximum Tolerated Dose (MTD) of MVT-5873 as monotherapy (Group A), in combination with a standard of care chemotherapy (Group B), for a Q2 week schedule (Group D), an MTD of MVT-5873 for a Q4 week schedule (Group C), and an MTD for a Q2 week schedule of MVT-5873 in combination with mFOLFIRINOX (Groups E and F). Each group utilized a conventional 3+3 study design to identify the MTD and recommended phase 2 dose (RP2D).

Following the definition of the MTD in each group, the RP2D of MVT-5873 as a single agent and in combination with mFOLFIRINOX was defined. Following completion of monotherapy dose escalation, an expansion cohort of 30 additional subjects was treated at the RP2D for Group D. Subjects were subdivided into two groups of 15 subjects; those without peripheral blood expression of C19-9 and those with peripheral blood expression of CA19-9. MVT-5873 pharmacokinetics (PK) and pharmacodynamics (PD) were determined for each group.
