You may qualify if…

Age ≥18 years at the time of informed consent and have provided signed informed consent for the trial.
Willing and able to comply with all aspects of the protocol.
Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1.
Life expectancy ≥3 months.
Diagnosed with histologically confirmed locally advanced and nonresectable, or metastatic disease.
Have received at least one line of prior systemic therapy or no alternative therapy to prolong survival exists.
Have received no more than 4 prior lines of systemic therapy for advanced disease. Prior therapy in an adjuvant or neoadjuvant setting is not considered as a prior line of systemic therapy.
Have measurable disease per RECIST 1.1 as assessed by the local site investigator and/or radiologist. Lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions.
Have provided archival tumor tissue sample or newly obtained core or excisional biopsy of a tumor lesion not previously irradiated. If previously treated with anti-PD-1/PD-L1 therapy, tumor tissue sample obtained following the most recent anti-PD-1/PD-L1 therapy is required. Formalin-fixed, paraffin embedded (FFPE) tissue blocks are preferred to slides. Newly obtained biopsies are preferred to archived tissue.
Left ventricular ejection fraction (LVEF) greater than 50% on echocardiography or multiple gated acquisition (MUGA) scan.
Patient has organ function as shown by the following:
Absolute neutrophil count (ANC) ≥1.5 x 109/L.
Hemoglobin ≥9 g/dL (which may be reached by transfusion 2 weeks prior to the start of the study treatment).
Platelets ≥100 x 109/L (which may be reached by transfusion).
International normalized ratio (INR) ≤1.5.
Calcium (corrected for serum albumin) within normal limits (WNL) or ≤ grade 1 severity according to NCI-CTCAE version 5.0 if judged clinically not significant by the Investigator. Patients concomitantly taking bisphosphonates or denosumab for calcium correction are eligible. (only applicable to Observations I and III)
Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤3.0 x upper limit of normal (ULN) or <5.0 x ULN if liver metastases are present.
Total serum bilirubin ≤ ULN or ≤1.5 x ULN if liver metastases are present; or total bilirubin ≤3.0 x ULN with direct bilirubin below or within normal range in patients with well documented Gilbert's Syndrome. Gilbert's syndrome is defined as presence of episodes of unconjugated hyperbilirubinemia with normal results from cells blood count (including normal reticulocyte count and blood smear), normal liver function test results, and absence of other contributing disease processes at the time of diagnosis.
Serum creatinine ≤1.5 x ULN or calculated or directly measured creatinine clearance (CrCL) >30 mL/min.
HbA1c ≤8%. (Only applicable to Observations I and III)
A female participant is eligible to participate if she is not pregnant, not breastfeeding, and at least one of the following conditions applies:
Not a woman of childbearing potential Women are considered post-menopausal and not of child-bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g., age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) at least six weeks prior to Screening. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow-up hormone level assessment, is she considered not of child-bearing potential.
Woman of childbearing potential who agrees to follow contraceptive guidance during the treatment period and for at least 5 months after the last dose of Atezolizumab.
Highly effective contraception is defined as either:
Total abstinence: When this is in line with the preferred and usual lifestyle of the patient. (Periodic abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods] and withdrawal are not acceptable methods of contraception.)

You may not qualify if…

Have been discontinued treatment due to a Grade 3 or higher immune-related AE (irAE) from prior anti-PD-1or anti-PD-L1, or with an agent directed to another stimulatory or co-inhibitory T-cell receptor (eg, CTLA-4, OX 40, CD137).
Have received prior systemic anti-cancer therapy including investigational agents within 4 weeks or 5 half-lives, whichever is shorter.
Note: Participants must have recovered from all AEs due to previous therapies to ≤ Grade 1 or returned to baseline. Participants with ≤ Grade 2 neuropathy or alopecia may be eligible.
Have received prior palliative radiotherapy within 2 weeks of start of study treatment. Participants must have recovered from all radiation-related toxicities, not require corticosteroids, and not have had radiation pneumonitis. A 1-week washout is permitted for palliative radiation (≤ 2 weeks of radiotherapy) to non-central nervous system (CNS) disease.
Severe, uncontrolled tumor-related pain.
Have received a live vaccine within 30 days prior to the first dose of study drug. Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, Bacillus Calmette-Guérin (BCG), and typhoid vaccine. Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (e.g., FluMist®) are live attenuated vaccines and are not allowed. Non live COVID vaccinations or boosters should not occur during Cycle 1 or within 30 days prior to the first dose of study drug.
Are currently participating in a study of an investigational agent or have used an investigational device within 4 weeks prior to the first dose of study treatment.

Have known active CNS metastases and/or carcinomatous meningitis. Participants with previously treated brain metastases may participate provided they are radiologically stable, i.e., without evidence of progression for at least 4 weeks by repeat imaging (note that the repeat imaging should be performed during study screening), clinically stable and without requirement of steroid treatment for at least 14 days prior to first dose of study treatment.
Have known severe hypersensitivity to study treatment components.
Have an active autoimmune disease that has required systemic treatment in the past 2 years (i.e., with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not considered a form of systemic treatment and is allowed. Have a history of (non-infectious) pneumonitis that required steroids or have current pneumonitis.
Have a history of (non-infectious) pneumonitis that required steroids or have current pneumonitis.
Have an active infection requiring systemic therapy within 2 weeks prior to Day 1 of Cycle 1.
Participants with known human immunodeficiency virus (HIV) and/or history of Hepatitis B or C infections, or known to be positive for Hepatitis B antigen (HBsAg)/ Hepatitis B virus (HBV) DNA or Hepatitis C Antibody or RNA. Active Hepatitis C is defined by a known positive Hep C Ab result and known quantitative HCV RNA results greater than the lower limits of detection of the assay.
