Inclusion Criteria:
Histologically or cytologically confirmed squamous or non-squamous non-small cell lung cancer. Patients with known EGFR mutations, ALK or ROS1 rearrangements are not eligible.
Availability of archival biopsy tissue or willingness to undergo a "baseline" biopsy prior to initiation of the trial for biomarker analysis, including PD-L1 by IHC. Results of the PD-L1 testing are not required for enrollment.
Measurable disease defined as lesions that can be accurately measured in at least one dimension (longest diameter to be recorded) as ≥ 10 mm with CT scan, as ≥ 20 mm by chest x-ray, or ≥ 10 mm with calipers by clinical exam.
Prior use of an immune checkpoint blocker alone or in combination therapy. There is no limit on the number of lines of prior therapy a patient may have received.
At least 18 years of age.
ECOG performance status ≤ 1
Normal bone marrow and organ function as defined below:
- Absolute neutrophil count ≥ 1,500/mcl
- Platelets ≥ 100,000/mcl
- Hemoglobin ≥ 9.0 g/dL
- Total bilirubin ≤ 1.5 x ULN
- AST(SGOT)/ALT(SGPT) ≤ 3.0 x ULN or 5.0 x ULN in the setting of liver metastasis
- Serum creatinine ≤ 1.5 x ULN or CrCl ≥ 40 mL/min. If serum creatinine is >1.5 times the ULN, a 24-hour urine collection to calculate creatinine clearance must be performed
Adequate coagulation function as defined by:
- INR ≤ 1.5
- PTT/aPTT < 1.5 x ULN Note: Patients on full-dose anticoagulation must be on a stable dose of oral anticoagulant or low molecular weight heparin (LMWH) for a minimum duration of 28 days. If receiving warfarin, the patient must have an INR ≤3.0. For heparin and LMWH there should be no active bleeding (that is, no bleeding within 14 days prior to first dose of protocol therapy) or pathological condition present that carries a high risk of bleeding such as tumor involving major vessels or known varices.
Urinary protein ≤ 1+ on dipstick or routine urinalysis. If urine dipstick or routine analysis is ≥ 2+, a 24-hour urine collection for protein must demonstrate < 1000 mg of protein in 24 hours to allow participation
Because the teratogenicity of ramucirumab is not known, the patient, if sexually active, must be postmenopausal, surgically sterile, or using effective contraception (hormonal or barrier methods). Female patients of childbearing potential must have a negative serum pregnancy test within 7 days prior to first dose of protocol therapy. Should a woman become pregnant or suspect she is pregnant while participating in this study, she must inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study and for the duration of study participation.
Ability to understand and willingness to sign an IRB approved written informed consent document (or that of legally authorized representative, if applicable).
Exclusion Criteria:
-Treatment with cyclophosphamide, azathioprine, methotrexate, thalidomide, and anti-tumor necrosis factor [anti-TNF] agents) within 2 weeks prior to Cycle 1, Day 1.
Note: Patients who have received acute, low-dose, systemic immunosuppressant medications such as one-time dose of dexamethasone for nausea or premedication for contrast dye allergy are eligible. The use of inhaled corticosteroids for chronic obstructive pulmonary disease (COPD) and fludrocortisone for patients with orthostatic hypotension or adrenocortical insufficiency is allowed. Patients using up to 10 mg of prednisone or equivalent per day are eligible.
- A history of other malignancy ≤ 3 years previous with the exception of patients with a negligible risk of metastasis or death and with expected curative outcome such as adequately treated carcinoma in situ of the cervix, basal or squamous cell skin cancer, localized prostate cancer treated surgically with curative intent, or ductal carcinoma in situ treated surgically with curative intent or undergoing active surveillance per standard of care management including Rai Stage 0 chronic lymphocytic leukemia, prostate cancer with Gleason score ≤ 6 and prostate-specific antigen (PSA) ≤ 10 ng/mL.
- Having received any other investigational agents within 30 days or five times the half-life of the agent (whichever is sooner) of the planned start of the protocol therapy. Patients may be screened and consented but may not begin therapy within that 30 day washout period.
- Symptomatic or untreated asymptomatic brain metastases. Patients with treated brain metastases are eligible if they are clinically stable with regard to neurologic function, off steroids after cranial irradiation (whole brain radiation therapy, focal radiation therapy, and stereotactic radiosurgery) ending at least 2 weeks prior to randomization, or after surgical resection performed at least 28 days prior to randomization. The patient may have no evidence of Grade ≥1 CNS hemorrhage based on pretreatment MRI or IV contrast CT scan performed within 21 days before starting therapy.
- A history of allergic reactions attributed to compounds of similar chemical or biologic composition to atezolizumab, ramucirumab, N-803, any other immune checkpoint blockade, chimeric or humanized antibodies, fusion proteins, or other agents used in the study.
- A history of prior severe immune-related adverse events requiring permanent discontinuation of the checkpoint inhibitors including all grade 4 toxicities and selected grade 3 toxicities such as pneumonitis, pancreatitis, neurological, cardiovascular, ocular, or renal adverse events.
- The patient is receiving chronic antiplatelet therapy, including dipyridamole or clopidogrel, or similar agents. Once-daily aspirin use (maximum dose 325mg/day) is permitted.
- The patient has experienced any arterial thromboembolic events, including but not limited to myocardial infarction, transient ischemic attack, cerebrovascular accident, or unstable angina, within 6 months prior to first dose of protocol therapy. Patients with unresected primary tumors or local recurrence who develop Grade 3 and 4 venous thromboembolism during the study may also receive anticoagulation and continue ramucirumab therapy provided that the tumor does not confer an excessive bleeding risk, in the opinion of the patient's physician.
- Uncontrolled or poorly controlled hypertension with blood pressure > 160 mmHg systolic or > 100 mmHg diastolic for > 4 weeks despite standard medical management.
- The patient has a prior history of GI perforation/fistula (within 6 months of first dose of protocol therapy) or risk factors for perforation.
- The patient has experienced any Grade 3 or 4 gastrointestinal bleeding within 3 months prior to first dose of protocol therapy.

- Active tuberculosis.
- Active hepatitis B virus (HBV) or hepatitis C virus (HCV) infection with the former defined as HBV surface antigen (HBsAg) positive and HBV core antibody (HbcAb) positive with reflex positive HBV DNA. Note: Patients with past or resolved hepatitis B infection defined as having a negative HBsAg test and a positive HBcAb test or treated HCV with negative HCV RNA are eligible.
