What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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 study looks at how short-term and long-term exercise affects the immune system in people with slow-growing blood cancers like chronic lymphocytic leukemia (CLL) and indolent non-Hodgkin lymphoma (NHL). Researchers at Mayo Clinic will have 70 participants undergo a 12-week exercise program and measure changes in immune cells and function. The goal is to see if exercise can help these patients fight infections and delay the need for treatment.

What this could mean

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

Active substance
Exercise intervention
What this could lead to
If successful, this study could show that regular exercise strengthens the immune system in CLL and indolent NHL patients, potentially delaying disease progression and reducing infection risk.
What could go wrong
This is an early-stage observational study with only 70 participants. It is not designed to prove that exercise directly improves survival or delays treatment, and results may not apply to all patients.

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

Inclusion Criteria: * English speaking * Between the ages of 18-80 * Histologically confirmed diagnosis of indolent non-Hodgkin lymphoma (NHL) will be required to participate in Aim 2 (CLL/SLL only), aim 3 and 4 (indolent NHL) and aim 5 (indolent NHL) of this study Exclusion Criteria: * Healthy subjects participating in Aim 1 will be excluded if they have known cardiovascular or pulmonary disease (e.g. heart disease, coronary artery disease, chronic obstructive pulmonary disease \[COPD\], asthma, etc.) an orthopedic or musculoskeletal limitation which would limit ability to exercise or are a current or former smoker * Indolent NHL individuals receiving treatment must have least 8 weeks of planned treatment remaining and those who have already received treatment must be at least 6 months post and have no planned treatments during the 12-week intervention period to be eligible. Individuals that are participating prior to receiving treatment must not have any scheduled treatments during their participation. Individuals will be excluded if they have uncontrolled hypertension, cardiac illness, or are not approved by their oncologist to participate
