Inclusion criteria
* Adult patients (≥18 years of age) * Histologically or cytologically confirmed NSCLC with liver metastases * Eligible for immune checkpoint inhibitors per treating medical oncologist * Disease must be measurable per RECIST criteria * ECOG Performance status of 0 - 2 * Adequate organ function per protocol. * Allowable prior therapy includes adjuvant durvalumab, prior radiotherapy outside the upper abdomen. * Patients must be willing and able to sign an informed consent form. * Participants of childbearing potential willing to undergo pregnancy test and use contraception per Appendix.
Exclusion criteria
* Liver tumor burden which cannot be targeted with SBRT per treating radiation oncologist * Presence of uncontrolled intercurrent illness or significant comorbidities precluding participation in a clinical study as determined by investigator * Diagnosis of underlying parenchymal end stage liver disease (cirrhosis) or biliary disease (primary biliary cirrhosis). * Other invasive malignancy active within 1 years, excluding in situ cancers * Presence of psychiatric or substance abuse disorders that would interfere with compliance or safety * Has a known history of active Bacillus Tuberculosis (TB), Hepatitis B or Hepatitis C infection * Has received a live (active) vaccine within 30 days of enrollment. * Active autoimmune disease that has required systemic treatment in the past 1 years aside from hormone replacement therapy (ie. thyroxine, insulin, or physiologic corticosteroid replacement therapy) * Baseline corticosteroid use (\>10 mg prednisone daily or equivalent) at study entry * Pregnancy or breast feeding
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of patients who receive all fractions of radiotherapy as planned | Up to 0.5 years after start of study treatment | Feasibility determination. Analyzed with descriptive statistics. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Proportion of patients who develop grade 3 or higher toxicity | Up to 1 year after start of study treatment | Any serious adverse event that occurs within 60 days after treatment with SBRT or after this time frame and is considered related to the study treatment will also be reported. Analyzed with descriptive statistics. |
| Progression-free survival | Time Frame: Up to 3 years after end of study treatment | PFS defined as the time from start of treatment to date of radiological or clinical progression (leading to withdrawal from the study), or death from any cause, whichever comes first. Assessed Per RECIST v1.1; analyzed using Kaplan-Meier curves and descriptive statistics. |
| Overall survival (OS) | Time Frame: Up to 3 years after end of study treatment | OS defined as the time from start of treatment to death. This will be analyzed using Kaplan-Meier curves and descriptive statistics. |
| Proportion of patients with local control | Time Frame: Up to 3 years after end of study treatment | Freedom from local progression (local control) is defined as the lack of progression of the tumors treated by RT, either by tumor size or enhancement. Progression or development of new tumors elsewhere in the liver or outside of the liver would not constitute a local control failure. Tumors which increase in size or demonstrate new or increasing enhancement are considered progression. Analyzed using Kaplan-Meier curves and descriptive statistics. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Proportion of responders with increased frequency of circulating lymphocytes | Time Frame: Up to 3 years after end of study treatment | Flow cytometry quantification of circulating biomarkers. Analyzed with paired T-test. |
