Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The experimental treatment consists of a chemotherapy drug, PNU-159682 packaged inside an EDV™ nanocell targeted to the epidermal growth factor receptor (EGFR) to form the investigational product E-EDV-D682. The EnGeneIC Dream Vector (EDV) nanocell is used to transport the chemotherapy directly to the tumor via the blood stream where it attaches to the surface of EGFR expressing cancer cells causing the cancer cells to die.
The E-EDV-D682 are given at the same time as one other investigational product designed to boost the body's own immune system to fight the cancer. This investigational product consists of non-targeted EDVs carrying alpha-galactosylceramide (GC) called EDV-GC. The combination of these 2 drugs is known as E-EDV-D682/GC.
The trial is a randomized blinded Phase I/IIa study that aims to test the safety and efficacy of E-EDV-D682/GC in combination with gemcitabine and nab-paclitaxel. The trial consists of 2 cohorts:
* Cohort 1 is an initial safety run-in phase that includes at least six participants who will receive E-EDV-D682/GC in combination with gemcitabine and nab-paclitaxel to assess safety. If one or less of the participants experience a dose limiting toxicity (DLT), the randomization portion of the study will be activated. If two or more DLTs occur, then the dose level will be reduced for the following participants. Cohort 1 enrollment will be complete once the first six evaluable participants have completed the DLT evaluation period, the study will then proceed to the randomized, blinded expansion phase.
* Cohort 2 is the randomized phase II expansion phase of the trial:
Participants will be randomized 2:1 to ARM A or ARM B, respectively:
1. ARM A. E-EDV-D682/GC with gemcitabine and nab-paclitaxel (N = 92)
2. ARM B. Gemcitabine and nab-paclitaxel with placebo (N = 46)
The first treatment cycle for all participants will involve bi-weekly visits for 3 weeks with a treatment free week in week 4, followed by weekly visits for a further 3 weeks. Doses of E-EDV-D682/GC in 3mL of 0.9% sodium chloride are administered intravenously over 10 seconds. In week 8, tumor burden will be radiologically re-evaluated in accordance with immune Response Evaluation Criteria in Solid Tumors (iRECIST) guidelines to determine treatment response.
Subsequent cycles will consist of weekly visits for 7 weeks. Following each 7-week treatment period is a treatment free week in which tumor burden is radiologically re-assessed (Week 8). Treatment may continue until the patient or investigator deems it suitable to stop treatment, for example if serious side effects occur or if the participants disease continues to grow.
It is estimated that the study duration for participants in the active treatment phase will be approximately 6 months consisting of two weeks for screening, 16 weeks of treatment (2 cycles, depending on the disease state and tolerability to the IMP and a 30-35-day safety follow-up visit).

RANDOMIZED
PARALLEL
The study design is based on an initial safety run-in using a rolling 6 model prior to randomization into two treatment arms. The initial safety run-in (Cohort I) will assess safety and tolerability of E-EDV-D682/GC in combination with gemcitabine and nab-paclitaxel in subjects with metastatic PDAC. In Cohort 2 subjects will be randomized into two treatment arms consisting of E-EDV-D682/GC with gemcitabine and nab-paclitaxel or gemcitabine and nab-paclitaxel with placebo.

E-EDV-D682 is a product based on the EnGeneIC EDV™ technology. EDVs are bacterially derived nanocells 400 nm in diameter that can be packaged with a range of different chemotherapeutic drugs and specifically targeted to cancer cell receptors via single chain bispecific antibodies (BsAb).
E-EDV-D682 packages a chemotherapeutic payload PNU159682 into the EDV which targets the epidermal growth factor (EGFR) on cancer cells via a BsAb.
EDV-GC
EDV-GC is a product based on the EnGeneIC EDV™ technology. EDVs are bacterially derived nanocells 400 nm in diameter that can be packaged with a range of different drugs. EDV-GC packages the immunomodulatory adjuvant aplha-galactosyl ceramide (GC) into the EDV and is designed to recruit anti-tumor immune cells.
Gemcitabine

In this trial the safety and efficacy of E-EDV-D682/GC will be tested in combination with a reference therapy - gemcitabine and nab-paclitaxel.
Nab paclitaxel.
Nab-paclitaxel in combination with gemcitabine is routinely used as second-line therapy in metastatic PDAC patients who have either progressed on or are intolerant to 5-FU based combination in the first line setting.
