Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This study involves 60 patients with mucinous peritoneal tumour, including pseudomyxoma peritonei (PMP), that are not suitable for cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) or other potentially beneficial surgery.

The combination drug treatment of Bromelain and Acetylcysteine will be injected directly into the tumour or peritoneal cavity via a drain and allowed to dwell for 24 hours. The tumour will then be drained and a repeat treatment will be considered.

The injection will be performed under radiological guidance by an interventional radiologist though a percutaneously inserted drain. The drain will remain in situ for the treatment period. The aspiration/drainage and repeat drug treatments will be delivered via this drain. The dose of the drug is dependent on the calculated tumour dimensions and volume.

The expectation is that the drug combination will dissolve the tumour, allowing it to be drained. Remaining mucinous tumour that is unable to be drained will be considered for repeat drug treatments.

Outcomes
Primary outcome [1] 303572 0
The primary endpoint of this study will be based on tumour reduction following direct injection of combination Bromelain and NAC into the recurrent PMP mucin. An assessment of efficacy will be measured by volume of fluid aspirated from the tumour collection (dissolved tumour). The treatment will be seen effective if >25% of tumour volume is aspirated.
Timepoint [1] 303572 0
The primary timepoint will be achieved on the day of treatment based volume of tumour dissolved where the baseline (prior to injection) volume of tumour will be compared to the post treatment volume of tumour drained, occurring 3-5 hours post injection.
Primary outcome [2] 303742 0
Repeat radiological imaging via a CT scan will be utilised to confirm and provide an accurate and re-measurable response to treatment. The post treatment scans will be compared to the pre-treatment radiology. A radiologist will compare both pre- and post-treatment scans to measure response. The endpoint will be reached if radiological response of tumour to therapy is achieved based on a 25% reduction in tumour volume on 3-dimensional imaging and volumetric analysis.
Timepoint [2] 303742 0
The primary timepoint will be achieved on the day of treatment based on repeat radiology scanning where the baseline (prior to injection) volume of tumour will be compared to the post treatment volume of tumour (following drainage) radiology, occurring 3-5 hours post injection.
Secondary outcome [1] 339429 0
Progression free survival (increase >20%) of the treated area based on repeat CT scanning
Timepoint [1] 339429 0
18 months
Secondary outcome [2] 339430 0
Post intervention symptom scoring using a standardised quality of life questionnaires as a tool to assess symptoms (RAND, SF36, EORTC QLQ-30 core questionnaire, EORTC QLQ-C15-PAL, EORTC QLQ-CR29)
Timepoint [2] 339430 0
18 months
Secondary outcome [3] 339431 0
Side effects including but not limited to effect on coagulation, pain, anaphylaxis/sensitivity/rash, infection.
Timepoint [3] 339431 0
At the time of intervention, during the intervention, day following the intervention, 1 week post intervention, 1 month post intervention
Secondary outcome [4] 339432 0
Phamacokinetics (CL) of Bromelain and NAC in tumour removed via the drain - drug concentration assays will be performed on the tumour aspirated at each aspiration timepoint.
Timepoint [4] 339432 0
Bloods will be collected on the day of the drug treatemnt via an IVC 3 hours following the injection of the drug combination. This will be examined for serum drug concentrations. Bloods will also be taken at 24 hours and 1 week.
Secondary outcome [5] 339434 0
Determine the cost to the healthcare system of the direct injection treatment by collection of patient treatment related data and evaluated with the hospital's Network Manager Performance Unit that is responsible for providing activity performance and costing information and analysis to support performance management of health service. The total cost per patient includes all costs related to the authority of the New South Wales Health System.

Eligibility
Key inclusion criteria
Patients with PMP or mucinous tumour who are not candidates for CRS/HIPEC or other surgery, have soft to intermediate grade tumour and do not meet any exclusion criteria

Patients will be considered for entry into this study if they:

• Are 18 – 80 years old
• Have a mucinous tumour or pseudomyxoma peritonei (target or free intraperitoneal) as identified on prior histology
• Are considered at high risk for repeat surgery, or do not wish to explore repeat surgery and consent to the trial procedures
• Have soft to intermediate grade tumour as identified on prior histology or operation
• Are considered suitable for the trial based on multidisciplinary team meeting review

Tumour should not be hard tumour or caking and have a clear cystic or mucinous appearance as identified on radiology. Having hard tumour in one region does not exclude treatment in another area, provided the appearance is mucinous.

In the case of a target lesion, tumour located elsewhere will not exclude a patient from this study and these tumours may be treated if suitable. The tumour must be safely accessible percutaneously by an interventional radiologist to allow insertion of a catheter or drain
Minimum age
18 Years
Maximum age
80 Years
Sex
Both males and females

Key exclusion criteria
Exclusion criteria

Patients will be excluded from the study if they:

• Have a non-mucinous tumour recurrence (hard tumour)
• Have suspected fistulisation of the tumour into the gastrointestinal tract, invading or abutting major vessel or other area of concern
• Have an allergy to pineapples, papain or bromeliads, sulphur or Acetylcysteine (skin tests will be performed in any patient where allergy or sensitivity is unknown)
• Have a coagulation disorder of any kind or are on anticoagulant or anti-platelet therapy that can not be managed or withheld for the treatment period
• Are asthmatic
• Have infected tumour (pus on aspiration or indicated on blood test)
• Have other serious comorbidities where inclusion in the trial will subject the patient to a higher risk of adverse events
• Are unable to give fully informed and educated consent or are unable to comply with the standard follow up procedures of a clinical trial
• Considered by the interventional radiologist to not be percutaneously accessible

Statistical methods / analysis
The primary endpoint, dissolution of the mucin collection, will be assessed by the measurement of the volume aspirated following the drug therapy and at repeat radiological imaging. Statistical analyses will be performed using SPSS software for Windows or Mac, version 25 (2018). Independent t-test will be used to compare the differences in patients (as well as case-matched controls) with Cox Regression to compare for re-accumulation free survival, as well control for other confounding factors such as volume of disease and hardness of tumour, which we have previously studied. Treatment effects will be expressed as relative risk with a 95% confidence interval. Other secondary outcome measures will be analyzed using Fisher’s exact or Chi-square test. Continuous variables will also be analyzed by independent t-test. The specific quality of life, symptom and treatment questionnaire will be used to gather information on the impact of the patient’s disease and intervention. Data will be graphed as represented across all time points and analyzed using repeated measures of variance. Patients will be analyzed according to the intervention, regardless of compliance. A p-value of <0.05 will be considered statistically significant in all tests.
