What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study explores whether men with early prostate cancer on active surveillance would be willing to take dietary fibre supplements, such as inulin or psyllium. Previous research hints these fibres may reduce inflammation and slow tumour growth, but no one has asked patients about their views. Researchers will interview 10 men and hold a focus group to understand attitudes, barriers, and facilitators. The findings will help design a larger trial to test whether fibre supplementation can delay disease progression.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Dietary fibre supplements (inulin with or without psyllium)
What this could lead to
If patients find fibre supplements acceptable, this could pave the way for a larger trial testing whether inulin and psyllium can slow prostate cancer progression during active surveillance.
What could go wrong
This is a small interview study, not a treatment trial. It will not show whether fibre actually delays cancer, and any future benefits remain uncertain.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Participants over 18 years of age. 2. Participants with residence in North-East Scotland. 3. Participants must be fluent in the English language. 4. Participants on active surveillance. Exclusion Criteria: 1. Participants who do not speak fluent English will be excluded from this study. 2. Participants who were treated with surgery, radiotherapy, chemotherapy or anti-androgen therapy for their prostate cancer. 3. Vulnerable participants, classified as adults who do not have the capacity to consent for themselves, will not be included in the study. If the research team are made aware that someone has lost capacity then they will be withdrawn from the study.
