Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients randomised to the intervention arm will receive modified FOLFOX6 chemotherapy (mFOLFOX6). Each cycle of mFOLFOX6 will consist of:

- Oxaliplatin 85mg/m2 given as an intravenous (IV) infusion on day 1 of a 2 week cycle.
- 5-Flurouracil 400mg/m2 given as an IV infusion on day 1 of a 2 week cycle.
- Leucovorin 400mg/m2 given as an IV infusion on day 1 of a 2 week cycle.
- 5-Flurouracil 2400mg/m2 given as an IV continuous infusion over 46 hours, commencing on day 1 of a 2 week cycle.

The cycle will be repeated every 2 weeks.

Patients will continue their assigned treatment until progression, unacceptable toxicity or any of the reasons listed in protocol section 4.4.
Intervention code [1] 257452 0
Treatment: Drugs
Comparator / control treatment
Patients randomised to the control arm will receive gemcitabine chemotherapy. Each cycle of gemcitabine will consist of:


- Gemcitabine 1000mg/m2 given as an IV infusion on days 1, 8, 15 of a 4 week cycle.

The cycle will be repeated every 4 weeks.

Patients will continue their assigned treatment until progression, unacceptable toxicity or any of the reasons listed in protocol section 4.4.

Outcomes
Primary outcome [1] 259614 0
Progression free survival at 4 months
Timepoint [1] 259614 0
Progression free survival is measured as the interval between randomisation and documented evidence of disease progression, the occurrence of new disease or death from any cause. Disease progression will be defined by Response Evaluation Criteria in Solid Tumours (RECIST) v1.1 criteria and assessed every 8 weeks until progression.
Secondary outcome [1] 266414 0
Efficacy/activity of gemcitabine and FOLFOX as assessed by:
- Overall survival
- Time to progression
- Response rate according to RECIST v1.1
- CA19.9 response
Timepoint [1] 266414 0
- Overall survival time is measured as the time from the date of randomisation to the date of death due to any cause. Overall survival time will be censored at the date of the last follow-up visit for patients who are still alive.

- Time to documented disease progression is defined as the time from randomisation to the first date of documented disease progression or the occurrence of new disease. Disease progression will be defined by RECIST v1.1 criteria and assessed every 8 weeks until disease progression.

- Response rate according to RECIST v1.1. A tumour responder is defined as any patient exhibiting a best study response of complete response or partial response (based on computed tomography scan (CT scan)). Response will be assessed every 8 weeks until disease progression.

- CA19.9 will be assessed at baseline and 4 weekly from the start of treatment. CA19.9 response will be analysed as an exploratory endpoint using the following definition:
1. To be evaluable for response by CA19.9 requires 1 pre-treatment sample > twice the upper limit of normal in the absence of biliary obstruction, and at least 1 further sample after the start of treatment.
2. A response to CA19.9 has occurred if there is at least a 20% reduction in levels following the start of chemotherapy.
3. The date of response by CA19.9 is the date of the first sample with a 20% fall.
4. Documentation of any proven or suspected interval biliary sepsis or stenting is required for correlation.
Secondary outcome [2] 266415 0
Proportion of patients for whom a hENT1 result is obtained within a clinically useful timeframe.
Timepoint [2] 266415 0
Tissue samples for hENT1 testing will be collected prior to randomisation.
Secondary outcome [3] 266416 0
Progression free survival in each biomarker cohort.
Timepoint [3] 266416 0
Progression free survival is measured as the interval between randomisation and documented evidence of disease progression, the occurrence of new disease or death from any cause. Disease progression will be defined by RECIST v1.1 criteria and assessed every 8 weeks until progression.
Secondary outcome [4] 266417 0
To collect and analyse data from patient biospecimens
Timepoint [4] 266417 0
Tissue samples will be collected at baseline
Secondary outcome [5] 266418 0
Treatment related toxicity in each chemotherapy group
Timepoint [5] 266418 0
Toxicity will be assessed according to Common Terminology Criteria for Adverse Events (CTCAE) criteria v4.0 at baseline, prior to starting each chemotherapy cycle, at end of treatment and 30 days after the last study drug administration.
Secondary outcome [6] 266419 0
Ascertain if there is a relationship between biomarker status and treatment related toxicity
Timepoint [6] 266419 0
Toxicity will be assessed according to Common Terminology Criteria for Adverse Events (CTCAE) criteria v4.0 at baseline, prior to starting each chemotherapy cycle, at end of treatment and 30 days after the last study drug administration.
Secondary outcome [7] 266420 0
Establish a tissue bank from patients treated with and without gemcitabine to support further biomarker studies
Timepoint [7] 266420 0
Tissue samples will be collected at baseline
