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

Condition or disease Intervention/treatment Phase
Pancreatic Adenocarcinoma Metastatic Drug: Nab-paclitaxel Drug: Gemcitabine Genetic: VCN-01 Phase 2

Detailed Description:

Multi-center, open label, randomized, 2-parallel arm, phase IIb study of nab-paclitaxel and gemcitabine as SoC plus/minus VCN-01 in patients with metastatic pancreatic cancer. VCN-01 is a genetically modified adenovirus characterised by the presence of four independent genetic modifications on 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 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.
