Plain English summary of protocol

Background and study aims
Primary sclerosing cholangitis (PSC) is an chronic autoimmune disease of the bile ducts and liver. PSC patients often have inflammatory bowel disease (IBD). Four out of ten people with both PSC and IBD get cancer of the bile ducts, gallbladder, liver or bowel. There are no screening strategies which reduce hepatobiliary cancers and there is no treatment shown to help slow the rate of PSC or reduce cancer risk. Aspirin may have anti-cancer effects and help reduce the PSC-related cancer risk. The main aims of the study are to investigate if daily low-dose aspirin over a minimum of 5 years reduces cancer risk in PSC and IBD patients. The researchers will also be looking at the safety and tolerability of aspirin and liver transplantation rates. There will be future work conducted on samples and imaging to establish if PSC-related cancers can be detected.

Who can participate?
Patients aged 18 years and over at least 12 months after a diagnosis of PSC-IBD

What does the study involve?
Participants will be randomly allocated to take a placebo or 75 mg once daily (oral) aspirin. Participants will be followed for a minimum of 5 years. Patients will attend a screening visit, month 1 phone call, 6 monthly visits over 5 years, and end of treatment. Follow-up data will be collected yearly after 5 years for a maximum of 5 years. Urine and blood samples will be taken at the screening visit and every 6 months over 5 years.

What are the possible benefits and risks of participating?
If the trial shows aspirin significantly and safely improves cancer-free survival and overall survival in patients with PSC-IBD, then this could lead to a change in the standard of care treatment for these patients.
Patients may experience some mild side effects from taking aspirin but risks have been mitigated by careful review of the inclusion and exclusion criteria by healthcare specialists on the Trial Management Group (TMG) to help screen for contraindications for aspirin and the researchers have avoided putting patients with decompensated liver disease onto the trial. They are monitoring side effects at every visit and patients will have a patient diary and contact number for surveillance of side effects. They are giving disease-related questionnaires to pick up changes in the activity of liver disease and Inflammatory bowel disease to alert clinicians of clinical changes. All side effects will be managed by the local Principal Investigator. All side effects will be reported on the electronic data capture system and reviewed by the clinical trial team as well at committee meetings including the TMG and Independent Data Monitoring Committee (IDMC) to assess signalling for safety.
There is a possibility of redness, swelling and bruising after blood collection and participants may feel lightheaded or faint. The blood samples will be collected at the screening and 6 monthly follow up only. Trained medical staff will be on hand to deal with side effects and the patient will be given a contact card to call for any concerns. There will be some blood collection for research samples, but these are optional.
Patients' travel fees will be reimbursed. These extra visits will be explained in the patient information sheet and there will be a chance to ask questions at every timepoint. Patients have the option to withdraw at any timepoint if they do not feel comfortable attending extra visits.
A women’s health professor and Honorary Consultant in Obstetric Medicine was asked to join the Trial Management Group (TMG) to review the requirements for pregnant women to join the trial. It was deemed safe for pregnant women to join this trial. Further advice has been given in the protocol regarding the management of pregnant women and any side effects in this trial. We will be collecting additional data to monitor these patients and all patients will be monitored closely for side effects for the sub-study. All side effects will be reported on the electronic data capture system and reviewed by the clinical trial team as well at committee meetings including the TMG and Independent Data Monitoring Committee (IDMC) to assess signalling for safety.

Scientific titleAsp-PSC: effect of aspirin on reducing cancer & improving outcomes in primary sclerosing cholangitis
Study acronymAsp-PSC
Study objectivesPrimary objective:
To investigate if in patients with primary sclerosing cholangitis (PSC) and inflammatory bowel disease (IBD), a daily low dose aspirin lowers the risk of PSC-related cancer/high grade dysplasia, liver decompensation, the need for liver transplantation and all-cause mortality, compared to placebo, over a minimum 5-year period.

Secondary objective:
Safety and tolerability of aspirin in patients with PSC-IBD and effect on quality of life using disease-specific questionnaires.
