What Are the Treatments Tested in This Trial?

Interventions

• Atezolizumab
• Stereotactic Body Radiation Therapy

Trial Overview The trial is testing the effectiveness of combining radiotherapy with atezolizumab before surgical removal of the cancer. It aims to see how well patients do after this combined treatment followed by standard post-surgery care which may include chemotherapy.

How Is the Trial Designed?

Group I: SBRT with Neoadjuvant Atezolizumab Experimental Treatment 2 Interventions

After the MTD is determined, additional patients will be enrolled at this dose level to ensure 14 patients evaluable for the efficacy endpoints (MPR) at the planned interim analysis. The 6 patients treated at the MTD in phase I will be included if evaluable for MPR, so that additional 8 patients will be enrolled in this stage.

Group II: Phase 1 Lead-in SBRT with Neoadjuvant Atezolizumab Experimental Treatment 2 Interventions

Initially 3 patients will be enrolled to receive one dose of neoadjuvant atezolizumab with 3 fractions of 8 Gy SBRT (dose level 2, i.e. starting dose). If there are \< = 1 DLT related to the neoadjuvant therapy, another 3 patients will be enrolled at the same SBRT dose with only one cycle of neoadjuvant atezolizumab. And if there are \<= 1 DLT out of the 6 patients, then determine MTD at this dose level.
