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 Results may not be published yet.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

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This status has not been confirmed recently, so it may be out of date.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 early study tests whether applying low-intensity electric fields (TTFields) to the chest before lung cancer surgery is safe and affects cancer-related genes. About 18 adults with stage I-IIIA non-small cell lung cancer will wear a non-invasive device for a short time before their planned operation. The main goal is to learn how the treatment changes gene activity, not to cure the disease.

Study facts

What this study's own registry entry says, in plain language.

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 18 people

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

Expected to start

Jul 2026

An estimate. Start dates often move.

Expected to finish

Dec 2030

An estimate. End dates often move.

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.

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

Inclusion Criteria: 1. Diagnosis of stage I-IIIA NSCLC planned for surgical resection. 2. Eastern Cooperative Oncology Group (ECOG) 0-2 performance status. 3. Willingness and ability to undergo planned correlative studies, including imaging tests. 4. Fresh biopsy diagnostic material obtained from standard of care procedure to perform baseline correlatives (10-15 slides)-if not available, enrollment will be considered on a case-by-case basis after discussion with and approval by the Lead Site PI or Lead Site Co-Principal Investigator. 5. Ability to understand and the willingness to sign a written informed consent. 6. All men, as well as women of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 30 days following completion of therapy. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately. * 6a. A female of child-bearing potential is any woman (regardless of sexual orientation, marital status, having undergone a tubal ligation, or remaining celibate by choice) who meets the following criteria: * • Has not undergone a hysterectomy or bilateral oophorectomy; or * • Has not been naturally postmenopausal for at least 12 consecutive months (i.e., has had menses at any time in the preceding 12 consecutive months). 7. Age ≥22 years at time of screening. Exclusion Criteria: 1. Receipt of prior therapy for the current NSCLC. 2. Planned neoadjuvant therapy for the current NSCLC. 3. History of major allergic reactions attributed to adhesive or compounds in TTFields micro-array. 4. Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that, in the opinion of the investigator, would limit compliance with study requirements. 5. Pregnant or nursing patients due to the potential for congenital abnormalities and the potential of this regimen to harm nursing infants. 6. Use of electronic devices or prosthetics - i.e., pacemakers, defibrillators, spinal infusion pumps. Specific scenarios can be discussed with the Lead Site PI or Lead Site Co-Principal Investigator.
