Study type
Description of intervention(s) / exposure
This is an open-label, Phase I/IIa study of EGFR-targeted EDVs containing the cytotoxic drug PNU-159682 (E-EDV-D682), which is administered intravenously (IV) in combination with immunomodulatory EDV-GC in subjects with advanced pancreatic cancer and other EGFR expressing solid tumours who have failed first or second line therapy, or where other standard therapies are not appropriate.

The Phase I component of the study will enrol 5 patients per cohort (5 patients with advanced pancreatic and 5 patients with other EGFR expressing solid tumours), to evaluate the safety and tolerability of the combination of E-EDV-D682 with adjuvant EDV-GC.
The first treatment cycle for both cohorts (pancreatic patients and participants with other solid tumours), is identical and will comprise of two doses administered 30 minutes apart, the first a combination E-EDV-D682/GC followed by a dose of single agent E-EDV-D682. The 2 doses will be given twice per week for the first 2 weeks (8 doses). After which E-EDV-D682/GC and E-EDV-D682, will be administered weekly for 2 further weeks (4 doses) (12 doses over 4 weeks). Week 5 is treatment free, but tumour burden will be radiologically re-evaluated in accordance with iRECIST to determine treatment response.
Subsequent cycles will follow a weekly dosing schedule, where the same 2 doses, E-EDV-D682/GC followed 30 minutes after completion by E-EDV-D682, will be administered weekly for 4 weeks (8 doses). Following each 4-week treatment period is a treatment free week in which tumour burden is radiologically re-assessed (Week 5).

In order to foster tolerance & minimise potential infusion related reactions, the first dose of combination E-EDV-D682/GC at Cycle 1, will be given at a reduced dose level of 2.5 x 10^9. Subsequent doses (Doses 3, 5, 7, 9 and 11) will then be escalated incrementally until the target dose level, 8 x 10^9, is attained at Cycle 1, Dose 11.

Single agent E-EDV-D682 will commence at a starting dose of 2 x 10^9 at Cycle 1, Dose 2, escalating to a maximum dose level of 7 x 10^9 by Cycle 1, Dose 12. All subsequent cycles of both the combination and E-EDV-D682 alone will be administered at the maximum dose levels attained in Cycle 1.

Participants may continue to receive investigational medicinal product whilst they continue to derive clinical benefit with no prohibitive toxicity, or until the subject becomes intolerant to the study medication, the subject withdraws consent, or at the discretion of the Investigator if it is felt to be in the best interests of the participant to withdraw.

Post-review by the Safety Monitoring Board and authorization by said committee, the Phase IIa component (dose expansion) will open to enrolment. Up to an additional 35 patients/cohort will be recruited to further evaluate the safety and anti-tumour efficacy of the combination of E-EDV-D682 and EDV-GC (E-EDV-D682/GC) as per the schedule outlined.

Primary outcome [1] 319244 0
Assess the safety and tolerability of E-EDV-D682 with EDV-GC in subjects with advanced pancreatic cancer and other EGFR expressing solid tumours who have failed first or second line therapy or where other standard therapies are not appropriate.
Timepoint [1] 319244 0
Safety assessment will involve recording the incidence of Adverse Events (AEs) and clinically significant changes in vital signs and clinical laboratory tests. AE's and vital signs will be assessed pre-dose and then at 1, 2 and 3 hours post-dose infusion for all doses and at the safety withdrawal visit 30-35 days post-final dose.

The very common side effects reported are:
• Chills and shaking (rigors)
• Fever including night sweats
• Abnormalities of liver tests
• Fatigue and lethargy
• Nausea

The common side effects reported are:
• Abnormalities of electrolyte tests
• Headache
• Pain or discomfort at the site of the cancer
• Breathless
• Muscular weakness/aches

A designated Safety Review Committee will assess if any reported adverse event including Serious Adverse Events (SAE's) and Suspected Unexpected Serious Adverse Reactions (SUSAR's) are attributable to the study treatment and fulfill the protocol defined criteria of a Dose Limiting Toxicity (DLT).

Participants will be assessed for DLTs after the first 50 days of treatment. and will include the first 5 patients enrolled in each cohort. In the case of missed doses, the DLT evaluable period will be extended by 7 days for each missed dose so that a DLT evaluable subject is defined as, having received 9 doses and been evaluated for a minimum of 7 days following each dose.
Primary outcome [2] 319245 0
Assess anti-tumour response in subjects with advanced pancreatic cancer and other EGFR expressing solid tumours when administered E-EDV-D682 with EDV-GC.
Timepoint [2] 319245 0
Evidence of anti-tumour activity will be assessed radiologically, and response graded according to iRECIST criteria. The overall response for each subject will be recorded at Week 8 of every cycle of treatment for the duration of treatment. Results for best overall response will be presented for individual participants and for the whole cohort, or relevant subsets, if applicable using frequency counts and percentages.
Primary outcome [3] 319246 0
Assess overall survival (OS) in subjects with advanced pancreatic cancer and other solid tumours when administered E-EDV-D682 with EDV-GC.
Timepoint [3] 319246 0
Survival will be presented as months following administration of Dose 1 for individual subjects, and overall or for relevant subsets if applicable. Survival will continue to be monitored for the duration of the long term follow-up (every 3 months from the safety follow-up visit, for a period of 12 months, and then for the extent of the patients survival). Kaplan Meier curves will be utilised to determine percentage and median survival. There is no control arm for this study. Survival will be compared to historic survival data for individual tumour types.

Brief summary
The primary purpose of this trial is to evaluate the safety and efficacy of a combination treatment consisting of EDV's packaged with a chemotherapeutic targeted to cancer cells and an adjuvant therapy that is designed to boost the bodies own immune system to fight the cancer.
In Phase I the study will enrol 5 evaluable patients per cohort.
In Phase IIa the study, will enrol up to an additional 35 evaluable patients per cohort.
Therefore up to 40 evaluable subjects per cohort will be enrolled in the study.

Who is it for?
You may be eligible to enrol in this trial if you are aged 18 years old or older and have either advanced pancreatic cancer or any solid tumour that has been treated with at least one prior treatment regime or where other standard therapies are not appropriate.

Study details
All participants enrolled in this trial will receive combination treatment with the following:
1. The EnGeneIC Dream Vector(TM) (EDV(TM)). The EDVs are very small particles known as nanocells, which are made from Salmonella bacteria. The type of Salmonella is one that does not cause disease. The EDV is the delivery vehicle used to transport the study drug directly to the site of the cancer.
2. The Cancer Treatment. The study drug is a type of chemotherapy. The study drug is packaged inside the EDVs (E-EDV-D682) and is targeted directly to the site of the tumour, rather than the body’s healthy cells and tissues. The EDVs will also be packaged with another substance that is designed to boost the immune system, called EDV-GC.
3. Bispecific antibody. The EDV delivery system works in 2 ways, as well as carrying the study drug, the EDV surface is also coated with a bispecific antibody. A bispecific antibody is two antibodies linked together, such that one can attach to the EDV and the other to cancer cells. Once attached, the EDVs are taken up inside the cancer cells, and the study drug is delivered directly inside the cell itself, causing the cancer cell to die.

Treatment will be administered in 5-week cycles. The treatments are prepared in a syringe and administered into a vein (intravenous), over a period of 20 minutes using a special pump. Two doses of the treatment are given twice per week for the first 2 weeks, followed by weekly treatment for a further two weeks, with a treatment free week where a CT or MRI scanning is performed to evaluate the tumours response to treatment (Week 5). Treatment may continue until the patient or investigator deems it suitable to stop treatment, for example if serious side effects occur or if the patients disease continues to grow.

It is hoped that the findings from this trial will provide information on whether E-EDV-D682 and EDV-GC treatment may be safe and effective for the treatment of otherwise incurable pancreatic and other advanced solid tumours.
