PRIMUS002: A study looking at two neo-adjuvant chemotherapy treatments for pancreatic cancer in patients whose cancer is able to be operated on

PRIMUS 002: An umbrella phase II study examining two neo-adjuvant regimens (FOLFOX-A and AG) in resectable and borderline resectable Pancreatic Ductal AdenoCarcinoma (PDAC), focusing on biomarker and liquid biopsy development

Design outcomes

Primary

MeasureTime frame
1. Time to progression following FOLFOX-A treatment is assessed through CT scans at baseline, prior to radiotherapy and prior to surgery. Further scans will be performed as per standard of care to progression. 2. Efficacy of proposed biomarkers in predicting disease progression rates in FOLFOX-A arm. Tissue samples will be collected from the patients at baseline (under the Precision Panc Master Protocol), prior to radiotherapy and at surgery/progression.

Secondary

MeasureTime frame
1. Translational research assessment of cloncal evolution and acquired resistance mechanisms due to treatment, Response based on RECIST 1.1 post neo-adjuvant chemotherapy. The patient will have a CT scan at baseline, prior to radiotherapy and prior to surgery. Further scans will be performed as per standard of care to progression. 2. CAP tumour regression grade post surgery, this will be assessed by MDT after surgery 3. R0 rate post surgery, this will be assessed by MDT after surgery 4. Overall survival, this will be assessed at every chemotherapy visit, radiotherapy planning, radiotherapy, surgery and at every follow up visit (6, 9, 12, 18, 24, 36, 48, 60 months post registration) 5. Disease free survival, this will be assessed at every chemotherapy visit, radiotherapy planning, radiotherapy, surgery and at every follow up visit (6, 9, 12, 18, 24, 36, 48, 60 months post registration) 6. Safety and tolerability as assessed by NCI CTC 4.03, this will be assessed at every chemotherapy visit, radiotherapy planning, radiotherapy, surgery and at every follow up visit (6, 9, 12, 18, 24, 36, 48, 60 months post registration) 7. Neurotoxicity as assessed by GOG NTx4, this will be assessed montlhy while on chemotherapy, prior to surgery and at follow-up visits 8. Quality of life as assessed by EORTC QLQ-C30 version 3 and the pancreatic-specific QLQ-PAN26 QOL module, this will be assessed montlhy while on chemotherapy, prior to surgery and at follow-up visits
