Intervention model: SINGLE_GROUP
Intervention model description: Single Arm Therapeutic study using historical controls
Primary purpose: TREATMENT

Brief summary: This is a multicenter single arm phase II clinical trial. All eligible patients will receive:

Carboplatin (AUC 5) i.v. day 1 plus pemetrexed (500 mg/m2) i.v. day 1 plus atezolizumab 1200 mg i.v. day 1 plus bevacizumab 15 mg/kg i.v. day 1 every 3 weeks for up to 4 cycles.

Patients with non-PD after 4 cycles will be permitted to continue with maintenance therapy with pemetrexed plus atezolizumab plus bevacizumab every 3 weeks until the time of disease progression or intolerable toxicities.

Detailed description: The hypothesis of this study is that the addition of Atezolizumab (an anti-PD-L1 antibody), to the combination of Carboplatin plus Pemetrexed plus Bevacizumab, a vascular endothelial growth factor (VEGF) inhibitor, for the treatment of patients with stage IV non-squamous, non-small cell lung cancer (NSCLC) will improve progression free survival (PFS) compared with a historical control of carboplatin plus pemetrexed plus bevacizumab.

Eligibility criteria: Inclusion Criteria:

* Written informed consent and HIPAA authorization for release of personal health information. NOTE: HIPAA authorization may be included in the informed consent or obtained separately.

* Measurable disease according to RECIST v1.1 criteria within 28 days prior to registration with either PET/CT scan, CT scan of chest and abdomen, or CT chest including upper abdomen and adrenal glands which define stage IV disease.
* Patients who had disease progression greater than 1 year after completing prior adjuvant therapy for stage I - III are eligible as long as no systemic therapy was given for recurrence.
* No prior immunotherapy or antiangiogenic therapy.
* Prior platinum therapy or pemetrexed are permissible if previously given in the adjuvant setting for stage I-III disease and disease recurrence is \> 1 year from completion of therapy.
* If subject received major surgery or radiation therapy of \> 30 Gy, they must have recovered from the toxicity and/or complications from the intervention.

  * Aspartate aminotransferase (AST) ≤ 1.5 × ULN or \< 5x ULN if the transferase elevation was due to liver metastases
  * Alanine aminotransferase (ALT) ≤ 1.5 × ULN or \<5x ULN if the transferase elevation was due to liver metastases
  * International Normalized Ratio (INR) or Prothrombin Time (PT) \& aPTT ≤ 1.5 × ULN (unless subjects is receiving anticoagulant therapy, as long as PT or PTT is within therapeutic range of intended use of anticoagulants)
* Females of childbearing potential must have a negative serum pregnancy test within 7 days prior to registration. NOTE: A woman is considered to be of childbearing potential if she is postmenarcheal, 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).
* For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use two non-hormonal methods of contraception, including at least one method with a failure rate of \< 1% per year, during the treatment period and for 5 months after the last dose of atezolizumab or 120 days after the last dose of any study drug, whichever is later;

  * examples of non-hormonal 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. Must use "estrogen-free" hormonal method if this is chosen contraception method.
  * A barrier method may be used as the second contraceptive method. 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 postovulation methods) and withdrawal are not acceptable methods of contraception.
* Contraception method must begin starting from the time of informed consent until 120 days after treatment discontinuation.
* For men: Agreement to remain abstinent (refrain from heterosexual intercourse) or use a condom, and agreement to refrain from donating sperm, as defined below:
* With female partners of childbearing potential or pregnant female partners, men must remain abstinent or use a condom during the treatment period and for 120 days after the last dose of study treatment to avoid exposing the embryo. Men must refrain from donating sperm during this same period.
* 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 postovulation methods) and withdrawal are not acceptable methods of contraception.
* As determined by the enrolling physician or protocol designee, ability of the subject to understand and comply with study procedures for the entire length of the study
