OncoSil™ implanted with concurrent Standard of care Chemotherapy - either FOLFIRINOX or gemcitabine + Abraxane.

OncoSil™

Paul J Ross, MRCP MBBS

To evaluate the safety of OncoSil™ in a patient population undergoing standard chemotherapy treatment for pancreatic cancer. This study has been designed to satisfy regulatory requirements.

The clinical investigation will be conducted at approximately 15 sites in Australia, the United Kingdom and Europe (Belgium) involving 40 patients.

Detailed description

The purpose of this research study is to investigate the safety of an active implantable (radiological) medical device OncoSil™, when implanted into patients with pancreatic cancer, in conjunction with Standard of Care (SOC) chemotherapy. OncoSil™, is an experimental treatment and carries the active treatment "radioactive Phosphorous (32P)" inside inactive silicon particles. Once implanted, the OncoSil™ Microparticles will stay in the tumour permanently. The purpose of OncoSil™, is to deliver the action of 32P directly into a targeted tumour to destroy cancer cells.

40 Patients will be taking part in a single arm open label research study - which means that everyone in the research study will receive the investigational treatment OncoSil™, plus their prescribed standard chemotherapy regimen which will be either; FOLFIRINOX (FOLFIRINOX is the name of a combination of chemotherapy drugs used to treat advanced cancer of the pancreas) or gemcitabine + nab-paclitaxel (Abraxane).

Endpoints: Primary Endpoint:

• Safety and Tolerability

Secondary Endpoints:

Efficacy

* Local Disease Control Rate at 16 weeks
* Local Progression Free Survival (LPFS), within the pancreas
* Progression Free Survival (PFS), all sites
* Overall Survival (OS)
* Body weight
* Impaired function
* Pain Scores

The screening period will be performed within a 2 week period, followed by a treatment period of investigational visits which will occur weekly from Day 0 (Visit 1) until week 12, then 4 weeks later at week 16, and then at 8-weekly intervals until study participants reach documented progression of disease criteria for both LPFS and PFS which marks the end of study participation i.e. EOS visit.

An 8-weekly review of medical records will be used to monitor possible device or late radiation related adverse events, and oncology treatments/procedures administered for up to 12 months post OncoSil™ implantation.

Overall survival will be conducted via 8-weekly medical record reviews until study participant death, or until 104 weeks post the last study participant enrolled.

Activity (Dose): The intended average absorbed radiation dose per treated tumour is 100 Gy (+20%).

Risks associated with OncoSil™ and/or implantation procedure

The following adverse events, considered to have a causal relationship with OncoSil™ or procedure, were recorded during previous clinical studies:

* Procedure-related pain
* Abdominal pain and discomfort
* Lethargy
* Fever
* Nausea and vomiting
* Abnormal liver function tests

The incidence of complications after standard open pancreaticoduodenectomy for pancreatic or peri-ampullary tumours is around 50%. The amount of intra-operative blood loss is an important factor that determines the occurrence of postoperative complications. Therefore, any significant reduction of intra-operative blood loss will benefit the peri-operative course.

Pancreaticoduodenectomy (PD) is the only therapeutic option to cure patients suffering from pancreatic head or peri-ampullary tumors. The standard approach in PD is open surgery (OPD). With advancing technology, data from expert centers suggest minimally invasive or laparoscopic PD (LPD) to be safe and feasible, though randomized studies are lacking to show the clinical benefits of LPD vs. OPD.

Advantages of minimally invasive surgery over open surgery are reduced tissue damage, surgical trauma and immunosuppression.

The general objective of this study is to compare the intra-operative efficacy of LPD vs. OPD, and in particular the amount of intra-operative blood loss.

Study design Monocentric randomized trial to compare the amount of intra-operative blood loss in LPD vs. OPD. Patients expected to undergo portal vein resection/reconstruction or any simultaneous other type of surgery will be excluded from the study.

Two experienced surgeons will perform all procedures; RA will perform the open and BT the laparoscopic procedures. A pylorus-resecting PD will be followed by a trans-mesocolic end-to-side hepatico-jejunostomy (HJS), a pancreatico-gastrostomy (PGS), and an ante-colic gastro-enterostomy (GES). Da Vinci robotic assistance of the reconstruction in LPD is allowed for the HJS and the PGS, while the GES will be done with endo-staplers.

Statistical considerations Randomization will take place pre-operatively after informed consent has been obtained. Patients will be randomized into two groups (OPD vs. LPD) using permuted blocks of size 6. This implies that of each series of 6 consecutive patients, three patients will be randomized in each group. There are no stratification variables.

Monocentric randomized trial to compare the amount of intra-operative blood loss in LPD vs. OPD. Patients expected to undergo portal vein resection/reconstruction or any simultaneous other type of surgery will be excluded from the study.

Reference intra-operative blood loss levels are available from 138 patients (June 2009 - June 2012), without portal vein resection and without additional surgery. Analysis of these data reveals that these values follow a lognormal distribution; the log-transformed blood loss has a normal distribution with mean and standard deviation equal to 6.06 and 0.83, respectively. The corresponding geometric mean equals 427ml. Based on this distribution, 42.4%, 24.7% and 15.1% of the subjects are expected to have blood loss higher than 500, 750 and 1000 ml, respectively. It is assumed that the treatment (LPD) will lead to a 50% reduction of the (geometric) mean. The impact of this assumption on the distribution of the blood loss levels implies that 15.1%, 6.4% and 3.1% of the subjects in the LPD-group are expected to have a blood loss level higher than 500, 750 and 1000 ml, respectively.

Based on a two-sided two-sample pooled t-test of a mean ratio with lognormal data, a total of 50 subjects is needed to detect a two-fold reduction in blood loss (with alpha set at 5%) with 90% power.
