Brief Summary
This randomized phase II trial studies how well atezolizumab with or without cobimetinib works in treating patients with bile duct cancer that has spread to other places in the body (metastatic) and cannot be removed by surgery (unresectable) or gallbladder cancer. 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. Cobimetinib is used in patients whose cancer has a mutated (changed) form of a gene called BRAF. It is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of cancer cells. Giving atezolizumab with cobimetinib may work better at treating patients with bile duct and gallbladder cancer.

Conditions
Outcome Measures
Primary Outcomes (1)
Progression Free Survival (PFS)
PFS within each treatment arm will be summarized descriptively and compared between groups, under the assumption of Cox proportional hazards, using the stratified log-rank test to account for tumor site. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.
From date of randomization to time of progression or death, assessed up to 1 year
Secondary Outcomes (4)
Number of Participants With Adverse Events
Up to 1 year
Objective Response Rate
Up to 1 year
Overall Survival
From date of randomization to time of death, assessed up to 1 year
Change in CD8+ Density Within the Tumor
Day 21
Other Outcomes (1)
Number of Participants With PD-L1 Expression
Up to 1 year
Study Arms (2)
Arm A (atezolizumab)
EXPERIMENTALPatients receive atezolizumab IV over 30-60 minutes on days 1 and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo CT or MRI and collection of blood samples throughout the trial and undergo tumor biopsy on study.
Arm B (atezolizumab, cobimetinib)
EXPERIMENTALPatients receive atezolizumab IV over 30-60 minutes on days 1 and 15 and cobimetinib PO QD on days 1-21. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo CT or MRI and collection of blood samples throughout the trial and undergo tumor biopsy on study.

Eligibility Criteria
You may qualify if:
- Pathologically confirmed metastatic or unresectable cholangiocarcinoma or gallbladder carcinoma (GBC), having received at least 1 prior line of systemic therapy, and received no more than 2 prior lines of therapy in the metastatic setting (disease recurrence =\< 6 months from the last dose of adjuvant therapy in resected patients will be considered the first line of therapy)
- Includes intrahepatic cholangiocarcinoma (IHC), extrahepatic cholangiocarcinoma (EHC), and gallbladder carcinoma (GBC), but not ampulla of vater cancers
- 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 \>= 10 mm (\>= 1 cm) with spiral CT scan, MRI, or calipers by clinical exam; assessment must be completed within 4 weeks of randomization
- Age \>= 18 years. Because no dosing or adverse event data are currently available on the use of cobimetinib in combination with atezolizumab in patients \< 18 years of age, children are excluded from this study
- Eastern Cooperative Oncology Group (ECOG) performance status =\< 1 (Karnofsky \>= 80%)
- Life expectancy of greater than 2 months
- Leukocytes \>= 2,500/mcL (within 2 weeks of randomization)
- Absolute neutrophil count \>= 1,500/mcL (within 2 weeks of randomization)
- Platelets \>= 75,000/mcL (within 2 weeks of randomization)
- Hemoglobin \>= 8 g/dL (within 2 weeks of randomization)
- 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) (within 2 weeks of randomization)
- Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase \[SGOT\])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase \[SGPT\]) =\< 3 x ULN (within 2 weeks of randomization)
- Creatinine clearance \>= 30 mL/min/1.73 m\^2 by Cockcroft-Gault OR creatinine \< 1.5 x ULN (within 2 weeks of randomization)
- 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) (within 2 weeks of randomization)
- Administration of atezolizumab and cobimetinib may have an adverse effect on pregnancy and poses a risk to the human fetus, including embryo-lethality; women of childbearing potential must agree to use either two adequate barrier methods or a barrier method plus a hormonal method of contraception to prevent pregnancy, or to abstain from heterosexual activity (complete 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; male patients must agree to use an adequate method of contraception, or to abstain from heterosexual activity (complete abstinence), prior to study entry, for the duration of study participation, and for 5 months (150 days) after the last dose of study agent
- +6 more criteria
You may not qualify if:
- Received chemotherapy or radiotherapy within 3 weeks prior to randomization or those who have not recovered to =\< grade 1 adverse events (other than alopecia) due to agents administered more than 3 weeks earlier; herbal therapy intended as anticancer therapy must be discontinued at least 1 week prior to randomization; for patients who received prior immunotherapy (eg anti-CTLA-4), at least five drug half-lives must have passed before the patient may enroll on this study; however, the following therapies are allowed:

- Treatment with systemic immunosuppressive medications (including, but not limited to, prednisone, cyclophosphamide, azathioprine, methotrexate, thalidomide, and anti-tumor necrosis factor \[anti-TNF\] agents) within 6 weeks prior to cycle 1 day 1;
- Patients who have received acute, low dose, systemic immunosuppressant medications (e.g., a one-time dose of dexamethasone for nausea) may be enrolled
- The use of inhaled corticosteroids and mineralocorticoids (e.g., fludrocortisone) for patients with orthostatic hypotension or adrenocortical insufficiency is allowed
