What was measured

Median time from start of treatment regimen (day 1 pembrolizumab) until documented local or distal failure or death from any cause. Will be estimated using the method of Kaplan-Meier. Per RECIST 1.1, Disease Progression is defined as ≥20%increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). The sum must also demonstrate an absolute increase of ≥5 mm. The appearance ≥1 new lesion(s) is considered progression.

Analysis population: Treated patients who were radiologically evaluable.

Groups in this outcome

Treatment (Pembrolizumab, BAY 1895344, SBRT)

Patients received pembrolizumab IV over 30 minutes on day 1 of each cycle. Starting on day 7, patients also receive 10 mg of BAY 1895344 PO BID on days 7-9 and 14-16 during cycle 1, and before and after each SBRT treatment during cycle 2 for a total of 9 doses. Beginning cycle 2, patients underwent SBRT starting between days 2 and 8 for 3 fractions with 2-3 days between fractions. Treatment repeated every 21 days for up to 2 cycles in the absence of disease progression or unacceptable toxicity (8 Gy x 3 SBRT). Patients also underwent CT scan and/or PET-CT scan and collection of blood samples throughout the trial. Biospecimen Collection: Undergo blood sample collection Computed Tomography: Undergo CT and/or PET-CT scan Elimusertib: Given PO Pembrolizumab: Given IV Positron Emission Tomography: Undergo PET-CT scan Quality-of-Life Assessment: Ancillary studies Stereotactic Body Radiation Therapy: Undergo SBRT
