NCT ID NCT04025229

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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looked at whether high-intensity interval training (HIIT) — short, intense exercise sessions — could have anti-cancer effects in women with endometrial cancer. Thirty women did 4 to 6 HIIT sessions before their scheduled surgery. Researchers then checked tissue samples for changes in a marker called Ki-67, which indicates how fast cancer cells are growing.

What this could mean

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

Active substance
High-intensity interval training (HIIT) exercise
What this could lead to
If this works, it could point toward exercise as a way to slow tumor growth before surgery for endometrial cancer.
What could go wrong
This is a very small, early study with only 30 participants and no comparison group, so results may not be reliable or apply to others.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Study facts

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 to 75 years

Sex

Female participants only

Healthy volunteers

Not accepted

Inclusion Criteria: * Patients with a diagnosis of endometrial cancer who are to undergo hysterectomy and staging * Between 40-75 years old * Body mass index of 30-50 kg/m2 * Endometrioid histology endometrial cancer * Presumed clinically early stage disease (disease confined to uterus only) * Have access to a Smart Phone * Have access to email * Agree to visit the exercise and sport science laboratory within 2 days of SOC visit for baseline testing if enrollment procedures cannot be done on the same day. Agree to visit clinic 2 (+/-2wks) weeks after surgery for SOC follow-up and post surgery visit, or willing to return to exercise and sport science laboratory 2 (+/-2wks) weeks post-surgery Exclusion Criteria: * Meets American College of Sports Medicine Guidelines for physical activity (150 minutes / week) * Currently doing HIIT * Hospitalization for a stroke, heart attack, or heart failure, or had surgery for blocked arteries in the past 3 months * Active diagnosis of psychosis or current uncontrolled substance abuse disorder * Insulin-dependent diabetes * Currently in another EC intervention * Severe dementia or other memory loss condition * Severe mental health disorder * Severely impaired hearing or speech * Inability to speak English * Musculoskeletal or neuromuscular condition that limits physical activity Any condition, in the opinion of the investigators, which would prohibit safe participation.
