Clinical Trial Summary

This is a clinical research study of an investigational (FDA BB-IND 10091) treatment for patients with pancreatic cancer (all stages) and advanced colorectal cancer that no longer responds to standard therapies.

The treatment is being evaluated for its effect on tumor growth. It consists of the placement (implantation) of small beads that contain mouse renal adenocarcinoma cells (RENCA macrobeads). The cells in the macrobeads produce substances that have been shown to slow or stop the growth of tumors in experimental animals and veterinary patients. It has been tested in 31 human subjects with different types of cancers in a Phase I safety trial. Phase II studies in patients with colorectal, pancreatic or prostate cancers are in progress.

Description:

This is an open-label Phase 2 clinical trial. The study will have a duration of 12 months and involve a potential total of four macrobead implants for each enrolled patient, with the implants being no less than three months apart.

The RENCA macrobeads are implanted intraperitoneally, using laparoscopic surgical procedures. The macrobeads remain permanently within the peritoneal cavity, even if patients withdraw from the study and/or begin new therapy (e.g. chemotherapy). After the formal phase of the trial is completed, subjects will be followed for life.

The intent of this Phase 2 trial is to assess efficacy, safety, and tolerability of RENCA macrobeads. Screening occurs within 28 days prior to first implantation. Enrolled patients are treated with a dose of 8 RENCA macrobeads per kilogram of body weight and observed for a minimum of 3 months prior to the next implantation. A maximum of 4 implantation procedures is possible. Day 0 is the day of implantation.

Prior to the start of the study, the Investigators ensured that the protocol and any attendant documentation were approved, in writing, by the Institutional Review Board. The study was conducted in compliance with the International Conference on Harmonization (ICH) of Technical Requirements for Registration of Pharmaceuticals for Human Use Good Clinical Practice Guidelines (E6 [R1]) for conducting, recording, and reporting studies, as well as for archiving essential documents.

The Investigators, the Medical Monitor of the sponsor, and the Data Safety Monitoring Board were responsible for monitoring safety parameters collected in the study. They, collectively, provided oversight and monitoring of the safety of the participants in the study.

Type	Measure	Description	Time frame	Safety issue
Other	Necrosis Comparison of Tumors Using PET-CT Scan	Tumors were assessed by positron emission tomography (PET)-CT scan at baseline and day 90 following the first RENCA macrobead implantation. The use of [13]F-fluorodeoxyglucose (FDG) uptake for the detection of lesions >1 cm in diameter allowed evaluation of metabolic activity. Decreases in FDG uptake were indicative of metabolic suppression of the tumor. The use of PET-CT scanning indicated anatomical localization, approximate size/volume of primary tumor and metastatic lesion(s), and assessment of metabolic activity of the tumor (as an indicator of metabolic health and necrosis).; Disease state is reported as a function of Tumor measurement divided by SUVmax. Changes were assessed between day 90 post RENCA macrobead implant and baseline values. Patients with no change = stable; patients with decreased values = decreased/necrosis, and patients with increased values = increased.	Baseline vs. Day 90 post-Implant 1
Other	Tumor Marker Response of mCRC Participants	Tumor markers included serum carcinoembryonic antigen (CEA) and cancer antigen 19-9 (CA 19-9), and were assessed on all participants with mCRC at baseline and at subsequent evaluation points to further assess tumor response to RENCA macrobead implantation. A tumor marker response was defined as a greater than or equal to 20% decrease in one or both of CEA or CA 19-9.	Change from baseline up to and including day 30 post-Implant 1
Other	Tumor Marker Response of Pancreatic Cancer Participants	Tumor markers included serum carcinoembryonic antigen (CEA) and cancer antigen 19-9 (CA 19-9), and were assessed on all participants with pancreatic cancer at baseline and at subsequent evaluation points to further assess tumor response to RENCA macrobead implantation.
