Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
1 capsule of Curcutex (Meriva® Curcumin Phytosome® 500 mg per capsule) twice daily (500 mg per dose, orally with breakfast and dinner) for 12 weeks. Participants will be advised to send a photo of the remaining investigational product at each follow up appointment (week 4, 8 and 12) so that the number of remaining capsules can be counted and confirmed by the researcher. Participants will be instructed to take any products remaining at study completion to their local pharmacy for disposal. Intervention use also will be recorded in a self-reported daily participant diary.

Outcomes
Primary outcome [1] 335708 0
Feasibility (recruitment success) will be measured using routinely collected recruitment data (i.e., number of expressions of interest, ability to meet the recruitment target of 30 participants enrolled in the allocated timeframe, and drop-outs).
Timepoint [1] 335708 0
These outcomes will be measured using routinely collected recruitment data (i.e., number of expressions of interest, enrolments, and drop-outs), which will be collected by the researcher throughout the trial period, and via an end of study survey, which will be self-administered online by participants at week 12 post-commencement of intervention (baseline).
Feasibility (recruitment success) will be measured throughout the trial period and determined after 8 months.
Primary outcome [2] 336034 0
Feasibility (patient experience), defined in the context of this study as the patients’ self-reported experiences related to trial logistics [i.e., blood collection, outcome measurements and appointments], will be measured at week 12 using a non-validated end of trial evaluation questionnaire designed specifically for this study, as well as a participant diary at weeks 4, 8 and 12. Both of these measures will be self-administered online by participants.
Timepoint [2] 336034 0
Feasibility (patient experience) will be measured at week 4, 8 and 12 post-baseline using a participant diary, and at week 12 using the end of trial evaluation questionnaire.
Primary outcome [3] 336035 0
Feasibility (acceptability and satisfaction with the intervention), defined in the context of this study as satisfaction with the intervention, will be measured at week 12 using a non-validated end of trial evaluation questionnaire designed specifically for this study, as well as a participant diary at weeks 4, 8 and 12. Both of these measures will be self-administered online by participants.
Timepoint [3] 336035 0
Feasibility (acceptability and satisfaction with the intervention) will be measured at week 4, 8 and 12 post-baseline using a participant diary, and at week 12 post-baseline using the end of trial evaluation questionnaire.
Secondary outcome [1] 425247 0
Safety is defined in this study as the absence of side effects and adverse events (AEs; new symptoms not previously experienced by the participant). Side effects and AEs will be recorded in a self-reported participant diary.
Timepoint [1] 425247 0
The diary will be collected at weeks 4, 8 and 12 post-baseline.
Secondary outcome [2] 425248 0
Severity of EoE-related symptoms will be measured using the Brief Esophageal Dysphagia Questionnaire (BEDQ). The BEDQ is a validated 8-item participant-administered instrument that uses a 14-day recall period to assess the frequency and intensity of EoE-related dysphagia.
Timepoint [2] 425248 0
The BEDQ questionnaire will be self-administered by participants at weeks 0, 4, 8, and 12 post-baseline.
Secondary outcome [3] 425249 0
EoE-related quality of life is defined as “an individual’s perceived physical and mental health over time”. This outcome will be measured using the Eosinophilic Oesophagitis Quality of Life Scale for Adults (EoE-QoL-A), version 2.0. The EoE-QoL-A is a validated disease-specific health-related QoL (HRQoL) measure for adults with EoE. The 24-item scale has a 6-question addendum for those on an elimination or elemental formula diet, and encompasses five domains: eating/diet impact, social impact, emotional impact, disease anxiety and choking anxiety. The EoE-QoL-A is the most widely used and well-established measure for assessing HRQoL in EoE
Timepoint [3] 425249 0
The scale will be self-administered by participants at weeks 0, 4, 8 and 12 post-baseline.
Secondary outcome [4] 425250 0
Absolute Eosinophil Count (AEC) is defined as the total number of eosinophils in an individual’s peripheral blood (white blood cells x Eosinophils / 100).
Timepoint [4] 425250 0
This outcome will be measured via a blood draw through an external pathology lab, undertaken at screening, and at weeks 4, 8 and 12 post-baseline.
Secondary outcome [5] 425257 0
This safety outcome will be measured using liver function test (LFTs) changes via pathology (blood draw),
Timepoint [5] 425257 0
The test will be conducted by an external pathology lab using a participant blood sample, which will be collected at screening and weeks 4, 8 and 12 post-baseline.
Secondary outcome [6] 425258 0
This safety outcome will be measured using kidney function test changes via pathology (blood draw),
Timepoint [6] 425258 0
The test will be conducted by an external pathology lab using a participant blood sample, which will be collected at screening and weeks 4, 8 and 12 post-baseline.
Secondary outcome [7] 425259 0
Severity of EoE-related symptoms will be measured using a Visual Analogue Scale (VAS) from 0 (free of any symptoms) to 10 (worst symptoms ever had) will also be self-administered by participants.
Timepoint [7] 425259 0
A VAS will be self-administered by participants at weeks 0, 4, 8, and 12 post-baseline.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
To ensure all investigators are blinded to treatment allocation (i.e., before randomisation), an statistician who is external to the research team will generate the allocation sequence and enter it into the computer data management system (REDCap). The statistician will be the only person with access to the randomisation sequence.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
An external statistician will generate the allocation sequence and enter it into the computer data management system. The statistician will be the only person with access to the randomisation sequence. Once the participant is formally enrolled in the study, the researcher will enter the participant’s information into an online database, for randomisation purposes. Once the data are entered, the participant will be randomised to a study arm via the inbuilt randomiser. The system will generate a participant number, which will be allocated to an intervention - either “Group A” (Meriva® 1000 mg per day) or “Group B” (Meriva® 2000 mg per day). These labels will align with the allocated participant number on the intervention label. This process will ensure the researcher is not able to influence the treatment assignment process.

Statistical methods / analysis
All data will be analysed using IBM SPSS v28.0.1.1. Analyses will be conducted on an intention-to-treat basis, with per protocol analyses undertaken for hypothesis generating purposes only. Descriptive statistics will summarise data and be presented as either means and standard deviations or medians with interquartile ranges for continuous data, or absolute and relative frequencies for categorical data. Paired T tests, RM-ANOVA or Linear mixed-effects models will be used to estimate the intervention effects for EoE-HRQoL-A, BEDQ, VAS and AEC.
