- Therapeutic exploratory (Phase II)
A plain-language read of the study's public EU CTIS listing. The study team confirms the details.
Who can take part
You may be able to join if
- Have pathologically proven newly diagnosed, treatment-naive stage I (i.e. ≤ 4 cm) NSCLC according to the 9th AJCC/UICC staging classification.
- Female participant of childbearing potential should have a negative serum pregnancy test within 72 hours prior to receiving the 1st dose of study medication.
- Be willing and able to provide written informed consent/assent for the trial.
- Be ≥18 years of age on day of signing informed consent.
- Should have measurable disease according to RECIST 1.1.
- Have a performance status of 0, 1 or 2 on the ECOG Performance Scale.
You likely can't join if
- Has a known driver mutation associated with lack of cemiplimab efficacy (e.g. EGFR, ALK, HER2, RET or ROS1). Patients with smoking-related targetable driver mutation (e.g. KRAS or BRAF non-V600E) are eligible for this study. If this is unavailable, a patient should have smoked ≥10 packyears to be eligible.
- Any infection requiring hospitalization or treatment with IV anti-infectives within 2 weeks of first dose of study medication.
- Uncontrolled infection with known HIV, hepatitis B or hepatitis C infection, diagnosis of immunodeficiency, and/or tuberculosis (active or latent). a. Participants with known controlled HIV infection (undetectable viral load on HIV RNA PCR) and CD4 count above 350 either spontaneously or on a stable antiviral regimen are eligible. For these participants monitoring will be performed per local standards. b. Participants with HBsAg positive who have controlled infection (serum HBV DNA PCR that is below the limit of detection and receiving anti-viral therapy for hepatitis B) are eligible. Participants with controlled infections must undergo periodic monitoring of HBV DNA. Participants must remain on anti-viral therapy for at least 6 months beyond the last dose of investigational study medication. c. Participants with HBsAg negative but total HBcAb positive are permitted with the following requirements: If serum HBV DNA PCR is above the limit of detection at screening, initiate HBV antiviral therapy before study entry. If serum HBV DNA PCR is below the limit of detection, periodic monitoring of HBsAg must be performed. d. Participants who are HCV Ab+ who have controlled infection (undetectable HCV RNA by PCR either spontaneously or in response to successful prior course of anti-HCV therapy) are eligible.
- Receipt of a live vaccine within 4 weeks of start of study medication
- Receipt of COVID-19 vaccination within 1 week of planned start of study medication or for which the planned COVID-19 vaccinations would not be completed 1 week prior to start of study medication
- Known hypersensitivity to the active substances or to any of the excipients.

- Should have measurable disease according to RECIST 1.1.
- Have a performance status of 0, 1 or 2 on the ECOG Performance Scale.
- Molecular analysis using next-generation sequencing (NGS) should be performed to identify oncogenic driver alterations and/or STK11 or KEAP1 mutations. If NGS is not available, the patient must have a smoking history of at least 10 packyears.
- PD-L1 TPS should be at least 50%.
- Should have an indication for SABR determined by the multidisciplinary team meeting.
- Demonstrate adequate organ function (as defined in Table 1 in the protocol). All screening labs should be performed within 14 days of treatment initiation.

Sexual abstinence
- Has a known mutation in STK11 and/or KEAP1 predictive of poor response to PD-(L)1 inhibitors.
- Is currently participating in or has participated in a study of an investigational agent or using an investigational device within 4 weeks of the 1st dose of treatment.
- Has received prior therapy with any antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways other than PD-(L)1 blockade, e.g. anti-CD137 or a CTLA-4 antibody.
- Has a known additional malignancy that is progressing or requires active treatment.
