Radiotherapy must have been completed a minimum of 14 days prior to registration, and patients must have recovered from adverse events (AEs) related to radiotherapy to < grade 1 (except alopecia)

• For Females: must be postmenopausal for at least 1 year before the screening visit, or are surgically sterile or not sexually active. Women of childbearing potential (WOCBP) must use 2 effective methods of contraception with a failure rate of less than 1% per year, during the entire study treatment period and for a period of 5 months after the last dose of study drug, or agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of the subject. WOCBP must have a negative serum pregnancy test during the screening period

• Adequate haematological function defined by white blood cell (WBC) count ≥2,500/mm3 with absolute neutrophil count (ANC) ≥1,500/mm3, platelet count - Adequate hepatic function defined by a total bilirubin ≤ 1.5 x the upper limit of normal (ULN) range (except subjects with Gilbert Syndrome, who can have total bilirubin < 3.0 mg/dL), serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 x ULN (≤ 5 if liver function test elevations are due to liver metastases)

• Adequate renal function defined by a serum creatinine ≤ 1.5 x ULN or an estimated creatinine clearance of ≥ 30 mL/minute for patients with creatinine levels above institutional limits (if using the Cockcroft-Gault formula)

• Stable medical condition, including the absence of acute exacerbations of chronic illnesses, serious infections, or major surgery within 4 weeks before registration, and otherwise noted in other inclusion/exclusion criteria

• Recovered (i.e., ≤ Grade 1 toxicity) from effects of prior anticancer therapy, except alopecia

• Ability to comply with protocol requirements

• The patient is able to provide written informed consent. Voluntary written consent must be given before performance of any study-related procedure not part of standard medical care, with the understanding that the patient may withdraw consent at any time without prejudice to future medical care.

Exclusion Criteria:

• Prior treatment with Atezolizumab or any other immunotherapy agents (anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, anti-CTLA-4 antibody, or any other antibody or drug specifically targeting T-cell costimulation or immune checkpoint pathways)

1. Subjects receiving bisphosphonates or denosumab are eligible provided treatment was initiated at least 14 days before first dose of trial treatment

2.

Subjects with brain metastases are eligible if metastases have been treated and there is no clinical evidence of progression for [lowest minimum is 2 weeks or more] after treatment is complete and within 28 days prior to the first dose of atezolizumab administration. In addition, subjects must be either off corticosteroids, or on a stable or decreasing dose of 10 mg daily prednisone (or equivalent)

Subjects with a condition requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalent) or other immunosuppressive medications within 14 days of registration will be not eligible. Subjects requiring hormone replacement with corticosteroids are eligible if the steroids are administered only for the purpose of hormonal replacement and at doses ≤ 10 mg or 10 mg equivalent prednisone per day. Topical, ocular, intra-articular, intranasal, and inhalational corticosteroids (with minimal systemic absorption) are permitted
