Study Overview

Study of Nab-Paclitaxel and Gemcitabine and Plus/Minus VCN-01 in Patients With Metastatic Pancreatic Cancer

A phase IIb, open-label, randomized study of Nab-Paclitaxel and Gemcitabine and plus/minus VCN-01 in Patients with Metastatic Pancreatic Cancer

Multi-center, open label, randomized, 2-parallel arm, phase IIb study of nab-paclitaxel and gemcitabine as Standard of Care (SoC) plus/minus VCN-01 in patients with metastatic pancreatic cancer. Gemcitabine and nab-paclitaxel are chemotherapy drugs approved by the FDA to treat pancreatic cancer. VCN-01 is a genetically modified adenovirus characterized by the presence of four independent genetic modifications in the backbone of the wild-type human adenovirus serotype 5 (HAd5) genome that confer tumor selective replication and antitumor activity. Approximately 92 patients in sites in North America and European Union (EU) will be recruited and randomized in a 1:1 ratio to one of two treatment arms (i.e., approximately 46 patients per treatment arm): * Arm 1- (SoC): Nab-paclitaxel and gemcitabine as SoC (28-day cycles). Patients in this arm will not receive the investigational medicinal product (IMP) VCN-01. * Arm 2- (VCN-01+ SoC): A maximum of two (2) doses of VCN-01 administrated in combination with nab-paclitaxel and gemcitabine as SoC (28-day cycles with exception of the IMP dose cycles, which will be 35-day cycles). A Data Monitoring Committee (DMC) will be convened at regular intervals to assess safety and to look at OS to determine if the trial can continue.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person’s general health condition or prior treatments.

Ages Eligible for Study:
