A positive response is defined as a ≥40% increase in the number of infiltrating cluster of differentiation 3 (CD3) + T cells between the pre-treatment biopsy at baseline and the post-treatment RP specimen. Thus, a negative response is a \<40% increase. The primary endpoint will include all enrolled subjects who receive at least 1 dose of study treatment and undergo RP. Analysis of the primary endpoint will be performed for each cohort independently
| Arm | Type | Description |
|---|---|---|
| Cohort A (atezolizumab monotherapy) | EXPERIMENTAL | Participants receive one (1) cycle of atezolizumab, 1200mg intravenously (IV) over 30-60 minutes on day 1 of a 14 day cycle. Radical Prostatectomy (RP) will occur 21 days (+/- 7 days) following the final dose of atezolizumab. No further study therapy will be administered following RP. |
| Cohort B (atezolizumab, etrumadenant) | EXPERIMENTAL | Participants will receive one (1) cycle of atezolizumab, 1200mg intravenously (IV) over 30-60 minutes on day 1 of a 14 day cycle and etrumadenant will be taken at a dose of 150mg PO, once daily, until 48 hours prior to RP, for at least 12 days. Radical Prostatectomy (RP) will occur 21 days (+/- 7 days) following the final dose of atezolizumab. No further study therapy will be administered following RP. |
| Cohort C (atezolizumab, tocilizumab) | EXPERIMENTAL | Participants will receive one (1) cycle of neoadjuvant atezolizumab and one (1) cycle of tocilizumab, 6mg/kg will be administered IV on day 1 of a 14 day IV prior to RP; atezolizumab will be administered in an identical fashion as Cohort A. RP will occur 21 days (+/- 7 days) following the final dose of atezolizumab. No further study therapy will be administered following RP. |
