Spots Global Cancer Trial Database for Endoscopic Assisted Electrochemotherapy in Addition to Neoadjuvant Treatment of Locally Advanced Rectal Cancer

Study Description

Brief Summary: The purpose of this study is to evaluate the efficacy and safety of neoadjuvant electrochemotherapy on locally advanced rectal cancer (UICC II-III) in an intended curative clinical setting, using an endoscopic electroporation device (EndoVE).

Detailed Description: Electroporation of cancer cells allows for a greater concentration of chemotherapy drugs to enter the tumor cells. The uptake of the chemotherapeutic drug is aided through the application of short electric pulses to the tumor mass (referred to as - Electrochemotherapy or ECT). The pulses make the tumor cells 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. Procedures with electrochemotherapy have previously 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. An endoscopic system (EndoVE ) for delivering the electric pulses to gastrointestinal tumors has recently been developed. The treatment procedure is similar to standard endoscopic colorectal examination (therapeutic colonoscopy) with the added element of an intravenous injection of bleomycin followed by the delivery of electric pulses (each one less than 1msec in duration). The pulses are endoscopically delivered directly to the tumor mass. The entire procedure is minimally invasive and completely ambulatory. A successful treatment will cause the tumor to 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 downsizing locally advanced rectal tumors prior to intended curative surgery. Time frame: 1. All patients will be treated with standard neoadjuvant chemoradiation therapy prior to enrollment in this trial. 2. Alle patients will have PET/MRI scans performed twice to evaluate treatment response (before and after ECT) 3. ECT treatment will be performed 4 weeks prior to surgery outlined by MDT. 4. Alle patients will be followed up for 3 months.
