PRIMUS 001: An adaptive phase II study of FOLFOX-A (FOLFOX and nab-paclitaxel) versus AG (nab-paclitaxel and gemcitabine) in patients with metastatic pancreatic cancer, with integrated biomarker evaluation



Study hypothesis

That FOLFOX-A will increase progression free survival in metastatic pancreatic cancer patients over AG

Ethics approval

Metastatic pancreatic cancer


Patients will call the CTU to randomise the patients and they will be randomised on a 1:1 basis with 50% receiving AG and 50% FOLFOX-A. Minimisation will be used to allocate patients between the treatment arms, the following factors will be used: treatment centre, whether or not the patient has liver metastasis, whether the primary tumour is in the head or the tail of the pancreas and the patients baseline CA19.9.

FOLFOX-A (nab-paclitaxel 150mg/m2 IV over 30 minutes, day 1 (administered first), Oxaliplatin: 85mg/m2, IV over 2 hours, day 1, Folinic acid: 350 mg flat dose or 400mg/m2, IV over 2 hours, day 1 (as per standard of care for folinic acid dosing), 5-FU infusion:1200mg/m2/day, as a continuous IV infusion over 2 days, day 1 and day 2 (for a total dose of 2400mg/m2 over 46 hours.)


AG (nab-paclitaxel: 125 mg/m2 IV over 30 minutes, day 1,8, and 15 (administered first and Gemcitabine 1000 mg/m2 IV over 30 mins on days 1, 8, and 15 (immediately following nab-paclitaxel).

When the patient progressed on CT scan treatment will stop and the end of treatment visit will take place with 28 days of the last treatment. At this visit any con meds will be reviewed, physical exam (weight, BP, pulse), ECOG, blood count and biochemistry, assessment of adverse events, CA19.9 and quality of life.

After that patients will be followed up every 3 months for the first year post randomisation, 18 months after randomisation, 24 months and then annually for up to 5 years. At these visits con meds, including any new cancer treatments will be recorded, ECOG, CA19.9, quality of life assessments and survival status will be recorded.

Intervention type



Phase II

Drug names

Primary outcome measure

Progression free survival as measured by IV contrast enhanced CT scan every 8 weeks from the date of randomisation to progression or death (from any cause), whichever occurs first.

Secondary outcome measures

1. Objective response rate based on RECIST v1.1 will be measured by contrast enchanged CT scan every 8 weeks until disease progression
2. Overall survival will be recorded at each study visit up to 60 months post randomisation
3. Safety and tolerability will be assessed using NCI-CTCAE v4. Adverse events will be collected at each treatment visit and the end of treatment visit.
4. Quality of life will be assessed using EORTC QLQ-C30, QLQ PAN26, ED-5D-5L monthly while on treatment and then at each follow up visit
5. Peripheral neuropathy will be assessed by the GOG-NTX4 questionnaire monthly while on treatment and then at each follow up visit
6. Health Economics: Resource use will be assessed by the EQ-5d-5L monthly while on treatment and then at each follow up visit. Information will also be collected regarding any inpatients stays in hospital during the course of the study

7.3. Haemoglobin ≥ 9.0 g/dL
7.4. WBC ≥ 3 x 109/l
7.5. Total bilirubin ≤ 1.5 x institutional ULN unless bilirubin rise is due to Gilbert’s syndrome
7.6. Aspartate transaminase (AST) and alanine aminotransferase (ALT) ≤ 2.5 x ULN (and <5 ULN in the presence of liver metastases)
7.7. Estimated creatinine clearance ≥ 60 mL/min (as calculated by Cockcroft and Gault or Wright formula or measured by EDTA clearance)
8. Negative serum Human Chorionic Gonadotropin (HCG) test for females with child bearing potential. Postmenopausal women must have been amenorrhoeic for at least 12 months to be considered of non-childbearing potential
9. Woman of child bearing potential, and men with female partners of child bearing potential, must agree to use adequate contraceptive measures (see section for the duration of the study and for up to 6 months after the completion of study treatment.
10. Compliant, and can be followed up regularly

The following additional inclusion criteria is ONLY required if recommended by the independent Data Monitoring Committee after interim review of study data (sites will have been informed by the CRUK CTU if this is the case):
11. Patient must be biomarker positive as fed back after central Precision-PANC diagnostic testing
