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 This study
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
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 Results may not be published yet.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

Summary

This pilot study will test whether a 12-week Korean-style Mediterranean diet, combined with daily step tracking, is feasible for people with MGUS or smoldering myeloma. Twenty adults will receive dietary counseling and a wearable device to monitor activity. Researchers will measure changes in diet adherence, body weight, inflammation, and other health markers to see if this lifestyle approach might help manage these conditions.

What this could mean

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

Active substance
Korean-style Mediterranean diet and physical activity monitoring
What this could lead to
If successful, this could show that diet and exercise changes may help manage MGUS or smoldering myeloma and possibly delay disease progression.
What could go wrong
This is a very small pilot study with only 20 people and no comparison group, so results may not be generalizable. It tests feasibility, not effectiveness, and may not lead to clear health benefits.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 20 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Expected to finish

Jul 2027

Show the full entry requirements

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

Inclusion Criteria: Participants must meet all of the following: Adults aged 19 to 80 years at the time of enrollment. Diagnosed with MGUS (Monoclonal Gammopathy of Undetermined Significance) or Smoldering Multiple Myeloma (SMM) according to standard criteria. Able and willing to follow a Korean-style Mediterranean diet (KORMED) for 12 weeks. Able to use a smartphone and wearable device to track daily physical activity. Willing to attend study visits and provide blood, stool, and questionnaire data at scheduled time points. Able to understand the study procedures and provide written informed consent. Exclusion Criteria: * Participants will not be eligible if they meet any of the following: Diagnosis of active multiple myeloma requiring treatment. Current participation in another interventional clinical trial. Severe liver, kidney, or heart disease that would make the diet or study procedures unsafe. Uncontrolled infection or serious medical condition that may interfere with participation. History of major gastrointestinal surgery that prevents adherence to the diet. Pregnant or breastfeeding, or planning to become pregnant during the study period. Allergy or intolerance to key components of the KORMED diet (e.g., fish, nuts, legumes) that prevents safe participation. Any condition, in the investigator's judgment, that would make participation unsafe or limit the ability to complete the study.
