About this study

The first phase of this study was an open label, randomized pilot study. Enrollment for this phase is now complete.

The second phase is a single arm phase 1 safety study. Patients planned to undergo precision hypofractionated radiation to all sites of oligoprogression will receive vancomycin for 1 week before RT and for 1 month after start of RT, and asked to provide stool and blood samples as outlined in the Safety Trial study table.

Being tested
Vancomycin, Precision hypofractionated radiation

What is being measured

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

  1. Randomized Pilot: Th1 immune response measured by cytokine expression (IFN gamma).

    The primary endpoint is IFN-gamma cytokine expression at Day 30 (+/- 2) collection compared to the pre-radiation level. It will be analyzed using generalized linear mixed models.

    Measured: 2 years

  2. Randomized Pilot: the safety of the addition of vancomycin to Stereotactic Body Radiotherapy

    The primary safety endpoint is uncontrolled diarrhea, as defined by CTCAE v4.0 > or = grade 3 (Increase of >=7 stools per day over baseline; incontinence; hospitalization indicated; severe increase in ostomy output compared to baseline; limiting self-care ADL). This will be evaluated during treatment and at 1 month, 3 months, 6 months and 12 months.

    Measured: 2 years

  3. Safety Trial: the safety of the addition of vancomycin to precision hypofractionated radiation

    Safety Trial: The primary safety endpoint is uncontrolled diarrhea, as defined by CTCAE v5.0 > or = grade 3 Increase of >=7 stools per day over baseline; hospitalization indicated; severe increase in ostomy output compared to baseline; limiting self care ADL). This will be evaluated weekly during vancomycin use and RT, at 1 month post-vancomycin, 3 months post-vancomycin, 6 months post-vancomycin and 12 months post-vancomycin.

    Measured: 3 years

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Vancomycin and Precision hypofractionated radiation in people with Early Stage Non-Small Cell Lung Cancer, run by Abramson Cancer Center at Penn Medicine 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?

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: looking for participants now, as of the sponsor's last update on 14 Jan 2026. 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. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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

Contact Ching Lai (267-250-9244, ching.lai@pennmedicine.upenn.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Randomized Pilot: Th1 immune response measured by cytokine expression (IFN gamma). (time frame: 2 years). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03546829, which also lists 1 linked publication.

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 14 Jan 2026.
