|ClinicalTrials.gov Identifier: NCT03076216|
Recruitment Status : Completed
First Posted : March 10, 2017
Last Update Posted : July 13, 2021
To evaluate the safety of OncoSil™ in a patient population undergoing standard chemotherapy treatment for pancreatic cancer. This study has been designed to satisfy FDA regulatory requirements.
The clinical investigation will be conducted at approximately 5 sites in the United States involving 20 patients.
|Condition or disease||Intervention/treatment||Phase|
|Unresectable Locally Advanced Pancreatic Carcinoma||Device: OncoSil™||Not Applicable|
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 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.
20 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 Gemcitabine or Gemcitabine + nab-paclitaxel (Abraxane).
Endpoints: Primary Endpoint:
• Safety and Tolerability
- 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.
8 weekly telephone contact will be used to monitor 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 and or telephone contact until subject death, or until 104 weeks post the last subject enrolled.
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
- Nausea and vomiting
- Abnormal liver function tests

OncoSil™ plus SOC Chemotherapy
OncoSil™ implanted with concurrent Standard of Care chemotherapy either gemcitabine or gemcitabine + Abraxane
The implantation of OncoSil™ under EUS
- Safety / Tolerability of Device as determined by the number of treatment emergent adverse events (TEAEs) evaluated according to CTCAE V4.0 [ Time Frame: Collected from the of signed informed consent until patient death or 104 weeks post last patient enrollment date, whichever is sooner] ]as determined by the number of treatment emergent adverse events (TEAEs) evaluated according to CTCAE V4.0
- Local Progression free survival within the pancreas [ Time Frame: Assessed from Baseline through to first confirmed CT documentation of local progression within the pancreas, an average of 12 months ]As assessed by the central reader review of successive CT scans throughout the study
- Progression free survival - entire body [ Time Frame: Assessed from Baseline through to EOS visit - an average of 12 months ]As assessed by the central reader review of successive CT scans throughout the study
- Overall survival [ Time Frame: Assessed from Baseline to 104 weeks post last patient first study visit] ]As assessed by the time from participant consent to participant death or their survival to 104 weeks past the first study visit on the last subject enrolled in the study.
- Body weight [ Time Frame: Assessed from Baseline through to EOS visit, an average of 12 months ]Measurement of subject body weight at each study visit
- Impaired function [ Time Frame: Measured at each study visit for the duration of the study, an average of 12 months ]as measured by changes in the Karnofsky Performance Status from screening
- Pain Scores [ Time Frame: Measured at each study visit for the duration of the study, an average of 12 months ]Pain as measured by the numerical rating scale (NRS) at each study visit
- Tumor Response [ Time Frame: Baseline measure from screening period, compared to Week 8 CT result, and then to 8 weekly CT results until local progression is determined, an average of 12 months ]as demonstrated by target tumour volumetric change (measured by a central reading centre)
