Summary
This study is investigating whether aiming to restore a healthy microbiota, gut barrier and digestion through faecal microbiota transplantation (FMT) alongside chemotherapy can effectively treat and relieve symptoms and pain in non-resectable pancreatic cancer. Who is it for? You may be eligible for this study if you are aged between 18 and 75 years of age, and have been diagnosed with non-resectable pancreatic cancer (i.e. pancreatic tumours that cannot be removed through surgery). Study details Participants will be randomly assigned to either receive FMT or placebo capsules in 2 separate treatment periods: one before chemotherapy and one 4 weeks after chemotherapy cessation. All participants will receive Folfirinox chemotherapy for either 3 or 6 months depending on the treating oncologist's review of their clinical response at 3 months. Safety, tolerability and efficacy data will be collected from participants over the course of their participation in this study. This study represents a unique opportunity to provide a novel and promising intervention for the management of pancreatic cancer and its symptoms to Australian patients to improve their health outcomes.
Eligibility
Inclusion Criteria14
- Participants who will be included are patients with a pancreatic cancer diagnosis who underwent an initial CT scan, and whose tumour is not surgically resectable at first assessment (including borderline resectable). The patients must be:
- Adults aged between 18 and 75 years of age
- Seen by a participating clinician for their first assessment between the study start date and the end of recruitment date
- Administered Folfirinox as a chemotherapy agent
- Eastern Cooperative Oncology Group Performance status (ECOG PS) of 0-1.
- Presenting an adequate bone marrow function with haemoglobin > 100 g/L, platelets > 100 X 10^9/L neutrophils > 1.5 X 10^9/L within 7 days of enrolment.
- Presenting an adequate renal function, with calculated creatinine clearance >40 mL/min (Cockcroft and Gault) within 7 days of enrolment.
- Presenting an adequate hepatic function with serum total bilirubin < 1.25 X upper limit of normal range (ULN) and alanine transaminase (ALT) or aspartate aminotransferase (AST)<2.5xULN (<5x ULN) if liver metastases present) within 7 days of enrolment
- Presenting a magnesium close to the lower limit of normal range within 7 days of enrolment.
- With a life expectancy of at least 12 weeks.
- Returning a negative pregnancy test around 72 hours before commencing study treatment (women of childbearing potential only).
- Speaking English or attending appointments accompanied with an English speaking next of kin
- Able to provide a signed informed consent
- Willing and able to comply with all study requirements, including treatment timing and nature of required assessments
Exclusion Criteria31
- Patients:
- Aged under 18 years old or over 75 years old at first assessment
- With resectable pancreatic tumour who are predicted to receive surgery
- Already receiving chemotherapy treatment either for pancreatic cancer or another cancer
- Who have already received chemotherapy treatment for pancreatic cancer.
- With prior pelvic radiotherapy, systemic chemotherapy, immunotherapy, approved proteins/antibodies or any investigational agent within 4 weeks prior to commencing study treatment.
- Who received radiotherapy within 14 days of commencing study treatment.
- With unresolved toxicities from prior systemic therapy or radiotherapy that, in the opinion of the investigator, does not qualify the patient for study treatment.
- Wwith medical or psychiatric conditions that compromise the patient’s ability to give informed consent or to complete the protocol.
- With prior systemic therapy, including with drugs targeting EGFR such as cetuximab, panitumumab or erlotinib
- Pregnant or breastfeeding women
- Severely immunocompromised patients (neutropenic as defined by <1,500 neutrophils cells/µL; this is to optimise the safety of FMT administration)
- With diagnosed dysphagia or other disorder affecting swallowing
- Who received prebiotic or probiotic within 4 weeks of randomisation (to exclude recent manipulation of the gut microbiota)
- Who used antibiotic within 8 weeks of randomisation (to exclude recent manipulation of the gut microbiota)
- For which the pancreatic tumour(s) were identified as a secondary cancer
- With known allergy to Creon and/ or Maxolon
- With known anaphylactic food allergy
- With a history of interstitial pneumonitis, pulmonary fibrosis or evidence of interstitial pneumonitis, or pulmonary fibrosis on baseline chest CT scan.
- With a history of Gilbert syndrome.
- With known cirrhosis, chronic active hepatitis, or chronic persistent hepatitis.
- With active bleeding diathysis.
- With uncontrolled clinically significant cardiac disease, arrhythmias or angina pectoris
- With active inflammatory bowel disease or other bowel disease causing chronic diarrhoea (defined as CTC grade 2 [CTCAE version 4.3])
- Who receive chronic treatment with immunosuppressives.
- Wth a known history of HIV seropositivity.
- Who have any severe and/or uncontrolled medical conditions or infections
- Who have a history of another primary malignant disease apart from non-melanotic skin cancer or carcinoma in situ of the uterine cervix or any other cancer treated with curative intent >2 years previously without evidence of relapse.
- Presenting brain metastasis.
- Women and partners of women of childbearing potential who are not using effective contraception. Adequate contraception must be used throughout study treatment and for 6 months following the completion of all study treatment.
- With history of serious drug adverse reactions.

Interventions
Faecal microbiota transplantation (FMT) as a co-treatment of chemotherapy with Folfirinox. FMT: Administered via oral capsules in two separate treatments. FMT will comprise whole stool anaerobically prepared and lyophilised from screened donors. Lyophilised, encapsulated FMT is supplied as 25g of lyophilised donor stool per 36 capsule dose (0.69g/capsule). FMT1: The first FMT treatment consists of a loading dose of 36 capsules taken over three days (12 capsules (0.69g/capsule)/day, total of 25g over three days). The patients will take 4 capsules with food at breakfast, lunch and dinner over the three days. This initial dose is provided before chemotherapy. FMT2: The second FMT treatment is done in two phases: - An initial loading phase: 36 capsules of FMT over three days (12 capsules/day). The patients will take 4 capsules with food at breakfast, lunch and dinner over the three days. - A consolidation phase: 3 capsules/day with food for 2 weeks. This second dose will be provided 4 weeks after chemotherapy cessation. Chemotherapy protocol: A script for Folfirinox will be provided with instructions on the day of FMT provision so that chemotherapy can commence two weeks after the first FMT treatment (week 0). A specific date of commencement will be marked on documentation to the patient and phone reminders will be provided by the trial team. The treating clinician will prescribe Creon (administered via oral tablets [2x25,000U] three times a day) to facilitate digestion during chemotherapy and afterwards. The participating oncologists will review the 3-month follow-up data to make a decision on the duration of chemotherapy. Depending on the patient’s response to chemotherapy (i.e., based on measurement of disease progression or regression that are part of the standard of care), Folfirinox will be prescribed for 3 or 6 months and taken every two weeks. The Folfirinox dosage will be as follow: • Oxaliplatin 85mg/m2 by intravenal infusion over 2 hours • Irinotecan 150mg/m2 by intravenal infusion over 90 minutes • Calcium folinate (Leucovorin) 50mg by intravenal bolus over 1 to 2 minutes • Fluorouracil 2,400mg/m2 delivered by intravenal infusion through a central line via pump over 46h
