FOLFIRINOX Versus OncoSil™ in Addition to FOLFIRINOX in Patients With Locally Advanced Pancreatic Adenocarcinoma

Phase 2
Recruiting
Conditions
Locally Advanced Pancreatic Cancer
Interventions
Drug: FOLFIRINOX chemotherapy
Device: OncoSil™
Registration Number
NCT05466799
Lead Sponsor
OncoSil Medical Limited
Brief Summary

The purpose of the study is to assess the safety and efficacy of OncoSil™ when given in addition to standard FOLFIRINOX chemotherapy for treatment of Locally Advanced Pancreatic Cancer

Detailed Description

Patients with Locally Advanced Pancreatic Cancer who have not received prior treatment to their pancreatic cancer will be informed about the study and the potential risks and benefits. After providing informed consent patients will undergo a 3 week screening period to confirm eligibility for the study. Patients who meet all eligibility criteria will be randomised 1:1 to either the control arm of up to 12 cycles of standard of care FOLFIRINOX chemotherapy or implantation of OncoSil™ in addition to the same FOLFIRINOX chemotherapy regimen. Patients will be followed for side side effects and palliative benefits during 4-8 weekly study visits and the objective efficacy of the treatment will be assessed by CT scans every 8 weeks. Quality of Life will be measured on various time-points using questionnaires.

Inclusion Criteria
  1. Histologically or cytologically proven adenocarcinoma of the pancreas.

  2. Unresectable locally advanced pancreatic adenocarcinoma according to NCCN 2021 guidelines.Staging and unresectability must be confirmed by central review of the baseline CT scan.

  3. Pancreatic target tumour diameter of < 7.0 cm (longest axis), as qualified by the central reading centre.

  4. Karnofsky Performance Status ≥ 70

  5. ≥ 18 years of age at screening.

  6. Considered fit to commence first-line standard FOLFIRINOX chemotherapy:

    i) Adequate renal function: serum creatinine less than 1.5 x upper limit of normal (ULN).

    ii) Adequate liver function: serum liver transaminases ≤ 3 x ULN and serum bilirubin ≤ 1.5 x ULN*.

    *For study participants with recent biliary obstruction treated by drainage (e.g. stent), serum bilirubin of > 1.5 x ULN will be accepted for study entry provided that serial levels demonstrate clear improvement. In addition, chemotherapy should not be commenced until serum bilirubin is ≤ 1.5 x ULN.

    iii) Adequate bone marrow function: white blood cells (WBCs) ≥ 3,000/mm3, absolute neutrophil count (ANC) ≥ 1,500/mm3, haemoglobin ≥ 9 g/dL, and platelets ≥ 100,000/mm3 iv) UGT1A1 polymorphism and DPD deficiency test performed and dose reductions applied as per local institutional practice.

  7. Provide signed Informed Consent.

  8. Willing and able to complete study procedures within the study timelines.

  9. Life expectancy of at least 3 months at the time of screening as judged by the investigator.

  10. Treated with or eligible to commence prophylactic treatment with a proton-pump inhibitor prior to implantation, and to continue to receive treatment for at least 6 months post implantation.

  11. Not pregnant, and if of childbearing potential, agrees to use adequate birth control (hormonal or barrier method of birth control or abstinence) prior to study entry and during the study and agrees not to donate sperm or ova, for the duration of the study and 12 months post implantation of the investigational device.

Exclusion Criteria
  1. Evidence of distant metastases, based on review of baseline CT scan.

  2. More than one pancreatic tumour lesion.

  3. Any prior radiotherapy or chemotherapy for pancreatic cancer.

  4. Pregnant or lactating.

  5. In the opinion of the investigator, EUS-directed implantation posing undue study subject risk. This includes:

    i) where previous EUS-FNA was considered technically too difficult to perform; ii) imaging demonstrates multiple collateral vessels surrounding or adjacent to the target tumour within the pancreas; iii) presence (or significant risk) of varices near to the target tumour. Note: The feasibility of implantation of the target tumour and assessment of risk can be repeated at any time between Screening Visit 1 and the implantation date. If any of the above risk features becomes apparent following subject screening and/or enrolment prior to and including at the time of OncoSil™ treatment, the patient should remain in the study but the implantation should be deferred or cancelled.

  6. History of malignancy, treated or untreated, within the past five years whether or not there is evidence of local recurrence or metastases, with the exception of basal cell carcinoma of the skin and cervical carcinoma in situ.

  7. Evidence of radiographic invasion into stomach or duodenum (if not certain, confirmation must be obtained prior to enrolment).

  8. A known history of hypersensitivity to silicon or phosphorous, or any of the OncoSil™ components.

  9. Any other health condition that would preclude participation in the study in the judgment of the investigator.

Primary Outcome Measures
NameTimeMethod
Safety and TolerabilityThrough study completion, an average of 18 months

The primary analysis for safety of OncoSil™ is defined by the Adverse Event profile

Local Disease Control Rate (LDCR) at 16 Weeks16 weeks after initiation of FOLFOX chemotherapy

The LDCR at Week 16 will be summarised as a count and proportion of subjects with Local Disease Control at 16 Weeks

Secondary Outcome Measures
NameTimeMethod
Local Progression Free Survival (LPFS), within the pancreasFrom date of enrolment until the date of first documented local progression or date of death from any cause, whichever came first, assessed up to 7 months after last enrolled patient

Local Progression Free Survival (LPFS) is defined as the time from enrolment to the date of the radiological scan used to determine local tumour progression or date of death from any cause, whichever comes first.

Progression Free SurvivalFrom date of enrolment until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 7 months after last enrolled patient

Progression free survival (PFS) is defined as the time from enrolment to the date of tumour progression or of recurrence (in case of complete response (CR) or resection of the primary pancreatic tumour), or death from any cause, whichever comes first.

Surgical resection rateThrough study completion, an average of 18 months

assessment of rate of secondary R0/R1 resection

Time to symptomatic progressionFrom date of enrolment until the date of symptomatic progression or date of death from any cause, whichever came first, assessed up to 7 months after last enrolled patient

Time to symptomatic progression is defined as the time between enrolment and worsening of cancer related symptoms as measured by the symptoms domains of QLQ-C30/PAN26

Overall SurvivalThrough study completion, an average of 18 months

Overall survival (OS) is the time from enrolment to the date of death from any cause.

Patient Reported OutcomesThrough study completion, an average of 18 months

EQ-5D, EORTC QLQ-C30 and PAN26 will be analyses per their validated methodology

Pain ScoresFrom date of enrolment until the date of first documented local progression or date of death from any cause, whichever came first, assessed up to 7 months after last enrolled patient

NRS and QLC-PAN26

weight will be assessed at all applicable study visits

Tumour responseFrom date of enrolment until the date of first documented local progression or date of death from any cause, whichever came first, assessed up to 7 months after last enrolled patient

RECIST 1.1 per central review

Target Tumour Volumetric ChangeFrom date of enrolment until the date of first documented local progression or date of death from any cause, whichever came first, assessed up to 7 months after last enrolled patient

A central reading centre will analyse all CT scans to measure target tumour volume changes from baseline.

Clinical Benefit ResponseFrom date of enrolment until the date of first documented local progression or date of death from any cause, whichever came first, assessed up to 7 months after last enrolled patient

Clinical Benefit Response is a composite endpoint consisting of weight, Performance Status and pain score and will be derived at 4 weekly intervals.The frequency and percentage of subjects with a clinical benefit response will be summarised

CA 19-9 responseFrom date of enrolment until the date of first documented local progression or date of death from any cause, whichever came first, assessed up to 7 months after last enrolled patient
