Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The approach simply allows a greater concentration of chemotherapy drugs to enter the tumour cells rather than healthy cells. The uptake of the chemotherapeutic drug directly by the tumour is aided through applying short electric pulses to the tumor mass (referred to as - Electrochemotherapy or ECT). The pulses make the tumour more porous which allows the drug easier access into the cancer cells, whereas other tissues and organs in the body remain relatively poor at absorbing the drug, thereby reducing the potential side effects on healthy tissues. This approach to date has been limited to skin based tumours due to the requirement for the electrodes to be placed directly in contact with the tumour. Procedures with electrochemotherapy have been applied to human patients in other countries of the EU, the US and Japan.
The drug concentration used is significantly reduced due to the more targeted absorption by the tumor and this significantly reduces side effects normally associated with chemotherapy.
A large number of preclinical and clinical Phase I and I/II studies have demonstrated the efficiency and safety of ECT. These studies have included patients with melanoma, head and neck squamous cell carcinoma, merkel cell carcinomas, basal cell carcinoma and adenocarcinoma nodules. Case reports concerning other primary tumours have also been reported.
The investigators have developed an endoscopic approach (EndoVe system) for delivering the electric pulses to internal cancers and are currently seeking to evaluate its efficacy in the treatment of inoperable colorectal cancer. The treatment procedure is similar to standard endoscopic colorectal examination (colonoscopy) with the added element of an intravenous injection of bleomycin followed after eight minutes by the delivery of electric pulses (each one less than 1msec in duration). The pulses are endoscopically delivered directly to the tumour mass. The entire procedure is minimally invasive and does not require intensive care follow up or stitches. If the treatment is successful the tumour will shrink in size in the weeks following the procedure.
The objective of this study is to investigate the efficacy and safety of this approach in reducing the size of the tumour.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
There are no known side effects of the instrument being tested. The pulse generator used has been certified by European electrical safety bodies charged with assessing compliance of new equipment with the present security rules for electrical devices. The electrical pulse generator has the CE mark and is approved for use clinically; the endoscopic electrodes used are a prototype system and are not currently CE approved.
The treatment is provided on an outpatient basis and does not involve an overnight stay. The procedure is very similar to a colonoscopy examination with the added element of a low dose chemotherapy drug being injected intravenously.
It reduces operative time; therefore there are fewer anaesthetic risks
At this time, the only option for patients with inoperable colorectal cancers is symptom relief e.g. a defunctioning colostomy or stent placement. Both carry a risk profile greater than the treatment with the EndoVe system.
Quicker recovery time- This is beneficial for the patient in terms of reduced exposure to the hospital environment through a shorter in-patient stay.
Research: The potential benefits of studying novel medical instruments in general include the development of new alternatives to conventional or existing therapies for certain cancers. In particular, the widespread availability of the novel instrument being tested here may lessen the requirement for more invasive procedures. It will reduce the amount of chemotherapy drug being used, therefore reducing the systemic effects as well as the side effects.
The approach is currently being applied to inoperable cases but in the future it may potentially be applied to both earlier stage cancers and other internal cancers e.g. oesophagus, stomach etc.
Because the treatment procedure is short (outpatient basis), it allows these patients greater time outside of the hospital environment to maximise and allowing for a greater quality of life (this for both individual patient and community at large).
If this treatment approach is proven to be safe and effective, patients with inoperable colorectal cancers will have a minimally invasive option for palliation of symptoms.

Study Groups

EndoVe treatment
Use of the EndoVe device to safely and effectively ablate rectal tumor tissue
EndoVe endoscopic electroporation
The EndoVe device enables the endoscopic treatment of gastrointestinal tumor tissues. The device is placed on the tumor tissue and an electrical pulse of less than 1msec is delivered. The tumor tissue becomes permeabilised and absorbs much greater concentrations of the drug than the surrounding healthy tissue

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Case reviewed by a multidisciplinary team (MDT) (surgery, radiology, oncology, gastroenterology) and there are no curable options with the standard of care. The MDT considers all available treatment options and enrolment to this study is agreed as being appropriate; Or the case is curable but patient refuses to undergo the standard of care. The MDT considers all possible alternatives, which are also discussed with the patient, and the MDT considers enrolment to this study as being the most appropriate option; Or patients with advanced local disease with impending obstruction on endoscopic evaluation who are otherwise not suitable for surgical intervention or stenting, the MDT would also consider these patients for enrolment into this study.
3. Men or women aged at least 18 years.
4. Performance status (Karnofsky \> 60% or ECOG/WHO \< 2).
5. Treatment free interval of at least 2 weeks after previously applied therapy.
6. Patients must be mentally capable of understanding the information given.
7. Patients must give written informed consent.
8. a) A female of Non-Childbearing potential (i.e. physiologically incapable of becoming pregnant) is eligible to participate in the study if she:
* has had a hysterectomy
* has had a bilateral oophorectomy (ovariectomy) - has had a bilateral tubal ligation
