You may qualify if…

• Eastern Cooperative Oncology Group (ECOG) Performance Status score of 0 - 2
• Adequate hematologic function defined as:
• Absolute neutrophil count (ANC) ≥1500/μL with one exception: Patients with benign ethnic neutropenia (BEN): ANC >1300/ μL
• Lymphocyte count ≥0.5 × 109/L (500/µL)
• Hemoglobin (Hgb) ≥9 g/dL (patients may be transfused to meet this criterion)
• Platelets ≥100,000/µL (without transfusion, within 7 days of enrollment)
• Adequate liver function defined as:
• Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤2.5 x the upper limit of normal (ULN)
• Total bilirubin ≤1.5 x ULN (patients with known Gilbert syndrome: serum bilirubin level ≤ 3 x ULN)
• Adequate renal function defined as serum creatinine ≤1.5 mg/dL (133 μmol/L) or calculated creatinine clearance ≥30 mL/min as calculated by the Cockcroft Gault formula
• For patients not receiving therapeutic anticoagulation: INR or aPTT ≤1.5 × ULN. For patients receiving therapeutic anticoagulation: stable anticoagulant regimen.
• For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods with a failure rate of <1% per year, during their participation in the study and for 5 months following last dose of study drug(s).
• A woman is considered to be of childbearing potential if she is postmenarchal, has not reached a postmenopausal state (≥12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus). The definition of childbearing potential may be adapted for alignment with local guidelines or requirements.
• Examples of contraceptive methods with a failure rate of <1% per year include bilateral tubal ligation, male sterilization, hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices, and copper intrauterine devices. The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or post-ovulation methods) and withdrawal are not adequate methods of contraception.
• Male patients with a female partner of childbearing potential or a pregnant female partner must remain abstinent (refrain from heterosexual intercourse) or use a condom must also refrain from donating sperm during the treatment period and for 5 months after the last dose of study drug. The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal or post-ovulation methods) and withdrawal are not adequate methods of contraception. Men must also refrain from donating sperm during their participation in the study
• Age ≥18 years.
• Willingness to provide a new pre-treatment tumor biopsy.
• Willingness and ability to comply with study and follow-up procedures.
• Ability to understand the nature of this study and give written informed consent.
• Measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1.
• Asymptomatic patients with treated or untreated CNS lesions are eligible, provided that all of the following criteria are met:
• Measurable disease, per RECIST v1.1, must be present outside the CNS.
• The patient has no history of intracranial hemorrhage or spinal cord hemorrhage.
• The patient has not undergone stereotactic radiotherapy within 7 days prior to initiation of study treatment, whole-brain radiotherapy within 14 days prior to initiation of study treatment, or neurosurgical resection within 28 days prior to initiation of study treatment.
• The patient has no ongoing requirement for corticosteroids as therapy for CNS disease.

You may not qualify if…

• History of severe allergic anaphylactic reactions to chimeric or humanized antibodies or fusion proteins
• History of any Grade 3 or 4 toxicities to a prior CPI treatment
• Known hypersensitivity to Chinese hamster ovary cell products or to any component of the atezolizumab or tiragolumab formulations
• Most recent immunotherapy ≤21 days and ≥ Grade 2 immunotherapy-related side effects, with the exception of alopecia.
• Use of systemic immunostimulatory agents (including, but not limited to, interferon and interleukin 2 [IL-2]) ≤28 days or 5 half-lives (whichever is shorter) prior to the first dose of study drugs.
• Treatment with chemotherapy in the first line setting.7. Treatment with investigational therapy within 28 days prior to initiation of study treatment.
• Treatment with systemic immunosuppressive medication (including, but not limited to, corticosteroids, cyclophosphamide, azathioprine, methotrexate, thalidomide, and anti-TNF- agents) within 2 weeks prior to initiation of study treatment, or anticipation of need for systemic immunosuppressive medication during the course of the study, with the following exceptions:
• Patients who received acute, low-dose systemic immunosuppressant medication or a one-time pulse dose of systemic immunosuppressant medication (e.g., 48 hours of corticosteroids for a contrast allergy) are eligible for the study.
• Patients who received mineralocorticoids (e.g., fludrocortisone), inhaled corticosteroids for chronic obstructive pulmonary disease (COPD) or asthma, or low-dose corticosteroids for orthostatic hypotension or adrenal insufficiency are eligible for the study.

• Patients receiving prophylactic antibiotics (e.g., to prevent a urinary tract infection or chronic obstructive pulmonary disease exacerbation) are eligible for the study.
• Requirement for use of denosumab during the study. Patients who are receiving denosumab for any reason (including hypercalcemia) must be willing and eligible to receive a bisphosphonate instead while in the study.
• Wide field radiotherapy (including therapeutic radioisotopes such as strontium 89) administered ≤28 days or limited field radiation for palliation ≤7 days prior to starting study drug or has not recovered from side effects of such therapy.
• Major surgical procedures ≤28 days of beginning study drug, or minor surgical procedures ≤7 days. No waiting required following port-a-cath placement.
• Symptomatic, untreated, or actively progressing CNS metastases. Patients who have received radiation or surgery for brain metastases are eligible if therapy was completed at least 2 weeks prior to study entry and there is no evidence of central nervous system disease progression, mild neurologic symptoms, and no requirement for chronic corticosteroid therapy. Anticonvulsant therapy at a stable dose is permitted.
