About this study

Official title: A Pilot Study of Metformin as a Chemoprevention Agent in Non-small Cell Lung Cancer

The purpose of this study is to learn whether it is better to receive the drug Metformin with standard of care for lung cancer or just standard of care.

Read the detailed description

Participants will need to be scheduled to undergo a surgical resection of their lung cancer at the Mayo Clinic in Rochester, Minnesota. They will be asked to provide a blood sample prior to their surgery. Samples of tumor tissue and normal lung tissue will be taken from the samples removed during your lung surgery. The tissue will be used to evaluate DNA. A skin biopsy at the edge of the incision that has already been made will be done during your surgery. We will take the skin and grow skin fibroblasts. Then we will reprogram the skin fibroblasts into induced pluripotent cells. You will be "randomized" into one of the study groups to either take Metformin for 6 months with your standard of care follow up or to receive standard of care follow up.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Evaluate Feasibility of Patient Randomization, Accrual, and Tissue Collection for Study Conduction

    To evaluate the feasibility of patient randomization, accrual, and tissue collection in a pilot study of metformin versus observation following resection of stage IA-IIIA lung squamous cell cancer for patients by assessing the reasons patients decline randomization, tracking accrual numbers, and tracking collected tissue and reasons why tissue was not collected.

    Measured: 2 years

  2. Number of Participants With 2-year Recurrence Free Survival

    To compare the 2-year recurrence free survival (RFS) rate between metformin and observation.

    Measured: 4 years

Secondary outcomes (2)
  1. Measure Metformin Sensitivity in Induced Pluripotent Stem Cells (iPS)

    To develop the metformin sensitivity index based on iPS cell line metformin sensitivity measurements from the first 20 patients randomized to the metformin arm. We will then To apply the metformin sensitivity index on the remaining 25 patients randomized to metformin and the 45 observation patients (70 patients total) to compare the 2-year RFS rate between metformin-sensitive and metformin-not-sensitive patients.

    Measured: 4 years

  2. Number of Participants With Adverse Events as a Measure of Safety

    To compare participant adverse events between metformin and observation arms using CTCAE version 4.

    Measured: 4 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Metformin in people with Lung Neoplasms and Carcinoma, Non-Small-Cell Lung, run by Mayo Clinic at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 10 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 19 Jun 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Evaluate Feasibility of Patient Randomization, Accrual, and Tissue Collection for Study Conduction (time frame: 2 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Mar 2020.
