Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients will be treated with steroids and proton pump inhibitor (PPI) therapy for a minimum of 6 weeks as part of the routine clinical management (prescribed by Gastroenterologist and/or in consultation with participants own GP). Only the study medication will be provided as part of the study. Participants will take the study medication in combination with routine clinical management for an initial period of 6 weeks, and then continue taking the study medication for a further 6 weeks (Total fucoidan/placebo supplementation will be 12 weeks). Participants will be randomised to one of two treatment groups.
(i) A formulation containing 100mg daily of 85% Maritech® (Marinova, Tasmania, Australia).
(ii) Placebo: same formulation as the fucoidan supplement but without the active ingredient

The active treatment will be administered via an oral gel, once per day. Participants will be asked to drink the gel slowly, allowing it to coat the oesophagus thoroughly, and asked to refrain from eating for 30 minutes afterwards.

To monitor compliance, participants will be asked to complete a daily symptom and medication diary, as well as take part in a follow up phone call at the half way point of the study (6 weeks). A text message/email reminder will be sent out twice per week. Participants will also be asked to return the bottle of supplement at the completion of the study for the research team to measure overall compliance.
Intervention code [1] 321460 0
Treatment: Drugs
Comparator / control treatment
Patients will be treated with either the active ingredient or the placebo control. The placebo control is the same formulation as the treatment group, minus the active (Fucoidan) ingredient.

The placebo medication will be administered via an oral gel, once per day. Participants will be asked to drink the gel slowly, allowing it to coat the oesophagus thoroughly, and asked to refrain from eating for 30 minutes afterwards.

To monitor compliance, participants will be asked to complete a daily symptom and medication diary, as well as take part in a follow up phone call at the half way point of the study (6 weeks). A text message/email reminder will be sent out twice per week. Participants will also be asked to return the bottle of supplement at the completion of the study for the research team to measure overall compliance.

Summary
Brief summary
Seaweeds comprise a diverse range of marine organisms
containing biologically active metabolites that are being explored for their therapeutic effect(s) on a range of health conditions. This project provides a novel opportunity to assess the role of inflammatory processes and the microbiome in the oesophagus in Eosinophilic oesophagitis (EoE). The aim of this study is to examine the clinical effectiveness of fucoidan supplementation in alleviating symptoms of Eosinophilic oesophagitis(EoE). To better understand the local immune pathways and responsiveness to supplementation oesophageal biopsy samples will be used to characterise immune and inflammatory signalling and to assess microbiome composition at the mucosal oesophageal surface.
