Brief Summary:
QUILT-3.088 NANT Pancreatic Cancer Vaccine: Phase II Randomized Trial of the NANT Pancreatic Cancer Vaccine vs. Standard-of-Care as First- Line Treatment for Patients with Metastatic Pancreatic Cancer.

Condition or disease Intervention/treatment Phase
Metastatic Pancreatic Cancer Drug: Gemcitabine Drug: Nab-paclitaxel Drug: Aldoxorubicin HCl Biological: ALT-803 Biological: ETBX-011 Biological: ETBX-021 Biological: ETBX-051 Biological: ETBX-061 Biological: GI-4000 Biological: GI-6207 Biological: GI-6301 Biological: haNK Drug: Avelumab Drug: Bevacizumab Drug: Capecitabine Drug: Cyclophosphamide Drug: 5-Fluorouracil Drug: Leucovorin Drug: Oxaliplatin Phase 2

Detailed Description:

This is a two-cohort, open-label, randomized phase 2 study to evaluate the safety and efficacy (as assessed by PFS) of the NANT Pancreatic Cancer Vaccine regimen (experimental arms) vs SoC therapy (control arms) as first-line treatment for subjects with metastatic pancreatic cancer.

Subjects will be enrolled into two independent cohorts based on ECOG status. Subjects with ECOG 0-1 will be randomized 1:1 to receive the NANT Pancreatic Cancer Vaccine regimen (experimental arm) or gemcitabine in combination with nab-paclitaxel (control arm), while subjects with ECOG 2 will be randomized 1:1 to receive the NANT Pancreatic Cancer Vaccine regimen (experimental arm) or gemcitabine monotherapy (control arm).

The experimental arms will be administered in two phases, an induction and a subsequent maintenance phase. The treatment regimen administered in the experimental arms will be identical for all subjects, independent of ECOG status. Subjects may continue induction treatment for up to 1 year. Those who have a complete response (CR) in the induction phase will enter the maintenance phase of the study. Subjects who experience ongoing stable disease (SD) or an ongoing partial response (PR) after 1 year of induction phase treatment may enter the maintenance phase at the Investigator's discretion. Subjects may remain on the maintenance phase of the study for up to 1 year.

Treatment in the study will be discontinued if the subject experiences confirmed PD or unacceptable toxicity, withdraws consent, or if the Investigator feels it is no longer in the subject's best interest to continue treatment. Subjects receiving treatment in the control arms may cross over to treatment in the induction phase of the experimental arms after experiencing PD. Subjects receiving treatment in the experimental arms with an initial assessment of PD per RECIST 1.1 may, at the discretion of the Investigator, continue to receive study treatment until PD is confirmed. The maximum time on study treatment is 2 years.


Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 1064 participants
Allocation: Randomized
Intervention Model: Single Group Assignment
Intervention Model Description: This is a randomized parallel group study comparing the NANT Pancreatic Cancer Vaccine and standard therapy with respect to efficacy and safety in treatment naïve patients with pancreatic cancer. Patients will be stratified by ECOG status and then randomized 1:1 to receive either the NANT Pancreatic Vaccine (n~532) or standard therapy with gemcitabine alone (ECOG 2; n~266) or combined with nab-paclitaxel (ECOG 0-1; n~266). Treatment may continue for up to 2 years or until documented progression (RECIST v 1.1) or unacceptable toxicity. Patients on standard therapy who progress or experience unacceptable toxicity may crossover to receive NANT Pancreatic Vaccine.
