This pilot phase I trial studies the side effects of atezolizumab in treating patients with cancer following adoptive cell transfer. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body’s immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.


I. To evaluate the safety of atezolizumab (MPDL3280A) administration in patients who have received adoptive cell transfer (ACT) prior to enrollment.

I. To evaluate the expansion of engrafted T cells following atezolizumab administration in the peripheral blood and within the tumor microenvironment.
II. To evaluate the phenotype and function of engrafted T cells following atezolizumab administration.
III. To observe and record anti-tumor activity.
IV. To evaluate the response rate using immune related Response Criteria (irRC) and Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1, or other tumor-specific criteria.
V. To evaluate survival outcomes and progression free survival using irRC and RECIST v1.1, or other tumor-specific criteria.

Patients receive atezolizumab intravenously (IV) over 30- 60 minutes on day 1. Cycles repeat every 21 days for a total of 17 doses over up to 12 months in the absence of disease progression or unacceptable toxicity. Patients undergo computed tomography (CT), magnetic resonance imaging (MRI), and biopsy on study. Patients also undergo blood sample collection on study.

After completion of study treatment, patients are followed up at 4 weeks, 8 weeks, and then every 3 months thereafter.


  1. Histologically or pathologically confirmed malignancy (hematologic or solid tumor) that is metastatic or unresectable and for which standard of care therapy does not exist or is no longer effective
  2. ACT infusion prior to study enrollment (cohorts include ACT with tumor infiltrating lymphocytes [TIL], human leukocyte antigen [HLA]-class I T cell receptor [TCR]-engineered lymphocytes, HLA-class II TCR-engineered lymphocytes, and chimeric antigen receptor [CAR]-engineered T cells)
  3. Prior ACT therapy should be completed, and residual disease documented by either radiographic progression or active disease observed on biopsy (i.e. hematologic or solid tumor malignancy must be deemed active by the treating investigator); the investigator may deem that the disease is active on the basis of a pre-treatment biopsy demonstrating viable tumor cells or clinical progression of disease (i.e. RECIST progression is not required)
  4. Solid tumor patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) as >= 20 mm (>= 2 cm) with conventional techniques or as >= 15 mm (>= 1.5 cm) with spiral computed tomography (CT) scan, magnetic resonance imaging (MRI), or calipers by clinical exam * Leukemia and non-Hodgkin’s lymphoma patients must have measurable disease according to the revised response criteria for malignant lymphoma
  5. Disease suitable for assessment by pre- and post-biopsies
  6. There is no limit to the number of lines of prior therapy; prior anti-programmed cell death (PD)-1 or anti-PD-ligand (L)1 therapy and other immunotherapies are allowed
  7. Prior anti-PD-1 or anti-PD-L1 therapy may not be administered after ACT and before study atezolizumab (MPDL3280A) administration
  8. All ACT related toxicities resolved to grade 1 with the exception of alopecia, vitiligo and endocrine abnormalities requiring replacement therapy which may be grade 2
  9. No prior other anti-cancer therapy, including ACT, for 28 days prior to study administration of atezolizumab
  10. Age >= 18 years. Because no dosing or adverse event data are currently available on the use of atezolizumab in patients < 18 years of age, children are excluded from this study, but will be eligible for future pediatric trials
  11. Eastern Cooperative Oncology Group (ECOG) performance status =< 2
  12. Life expectancy of greater than 3 months
  13. Absolute neutrophil count >= 1,000/mcL
  14. Platelets >= 75,000/mcL (>= 50,000 for patients with hematologic malignancies)
  15. Hemoglobin >= 8 g/dL
  16. Total bilirubin =< 1.5 x institutional upper limit of normal (ULN) (however, patients with known Gilbert disease who have serum bilirubin level =< 3 x ULN may be enrolled)
  17. Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT])/ alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 3 x ULN (AST and/or ALT =< 5 x ULN for patients with liver involvement)
  18. Creatinine clearance >= 30 mL/min/1.73 m^2 by Cockcroft-Gault
  19. International normalized ratio (INR) and activated partial thromboplastin time (aPTT) =< 1.5 x ULN (this applies only to patients who do not receive therapeutic anticoagulation; patients receiving therapeutic anticoagulation, such as low-molecular-weight heparin or warfarin, should be on a stable dose)
  20. Administration of atezolizumab may have an adverse effect on pregnancy and poses a risk to the human fetus, including embryo-lethality; women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 5 months (150 days) after the last dose of study agent; should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately
  21. Ability to understand and the willingness to sign a written informed consent document

**Clinical trials are research studies that involve people. These studies test new ways to prevent, detect, diagnose, or treat diseases. People who take part in cancer clinical trials have an opportunity to contribute to scientists’ knowledge about cancer and to help in the development of improved cancer treatments. They also receive state-of-the-art care from cancer experts... Click here to learn more about clinical trials.
