Post-menopausal is defined as aged more than 50 years and amenorrheic for at least 12 months following cessation of all exogenous hormonal treatments ii. Women under 50 years old would be considered postmenopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and with LH and FSH levels in the the post-menopausal range for the institution iii. Documentation of irreversible surgical sterilization by hysterectomy, bilateral oophorectomy, or bilateral salpingectomy but not a tubal ligation b.

Exclusion Criteria:

1. Patients under the age of 18

2. Inability to provide informed consent by either the patient or the authorized representative

3. Patients with known EGFR, ALK, ROS1, MET, and RET oncogenic driver alterations that have approved first-line targeted therapies are excluded from the study (All patients must have a tissue or blood-based testing to identify these driver alterations)

4. Patients with no detectable ctDNA or ctDNA VAF ≤ 0.3% on Guardant360 CDx at baseline

5. Subjects with untreated CNS metastases are excluded.

6. Subjects are eligible if CNS metastases are adequately treated and subjects are neurologically returned to baseline (except for residual signs or symptoms related to the CNS treatment) for at least 2 weeks prior to randomization. In addition, subjects must be either off corticosteroids, or on a stable or decreasing dose of 10 mg daily prednisone (or equivalent) for at least 2 weeks prior to randomization.

7. Subjects with carcinomatous meningitis

8. Subjects must have recovered from the effects of major surgery or significant traumatic injury at least 14 days before randomization

9. Subjects with previous malignancies (except non-melanoma skin cancers, and in situ cancers such as the following: bladder, gastric, colon, cervical/dysplasia, melanoma, or breast) are excluded unless a complete remission was achieved at least 2 years prior to randomization and no additional therapy is required or anticipated to be needed during the study period.

10. Other active malignancy requiring concurrent intervention.

11. Subjects with an active, known, or suspected autoimmune disease. Subjects with type I diabetes mellitus, and hypothyroidism only require hormone replacement, skin disorders (such as vitiligo, psoriasis, or alopecia) not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger are permitted to enroll.

12. Subjects with a condition requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalent) or other immunosuppressive medications within 14 days of randomization. Inhaled or topical steroids, and adrenal replacement steroids > 10 mg daily prednisone equivalent, are permitted in the absence of active autoimmune disease.

13. Subjects with interstitial lung disease that is symptomatic or may interfere with the detection or management of suspected drug-related pulmonary toxicity.

1. Uncontrolled hypertension, which is defined as systolic blood pressure > 160 mm Hg or diastolic blood pressure > 100 mm Hg despite optimal medical management.

2. Active coronary artery disease, including unstable all newly diagnosed angina within 3 months of study enrollment.

3. Myocardial infarction in the past 6 months.
