Brief Summary:
Data suggests that combining ramucirumab with immunotherapy in non-small cell lung cancer (NSCLC) patients who have previously received immune checkpoint blockers (ICBs) may be more effective than traditional therapy. The investigators propose a pilot study to test the combination of ramucirumab and atezolizumab in patients with advanced-stage NSCLC patients previously treated with ICB.

Arm Intervention/treatment
Experimental: Ramucirumab + Atezolizumab
  • Ramucirumab will be given intravenously over the course of an hour on an outpatient basis on Day 1 of each 21-day cycle at a dose of 10 mg/kg.
  • Atezolizumab will be given intravenously on an outpatient basis on Day 1 of each 21-day cycle at a dose of 1200 mg.
Drug: Ramucirumab
Ramucirumab is an investigational agent for this trial and will be supplied by Lilly Oncology, free of charge to the patient.
Other Name: Cyramza

Drug: Atezolizumab
The initial dose will be administered over 60 minutes (+/- 15 minutes). If the first infusion is tolerated without infusion-associated events, the second infusion may be delivered over 30 minutes (+/- 10 minutes).
Other Name: Tecentriq

Procedure: Peripheral blood draw
-Baseline and Cycle 2 Day 1

Procedure: Biopsy
  • If archival biopsy tissue not available, participant will undergo biopsy at baseline
  • When feasible, a repeated tumor biopsy will be obtained between Cycles 2 and 3 after the scheduled CT scan.

Primary Outcome Measures :
  1. Overall Response Rate (ORR) [ Time Frame: At 6 weeks ]
    • ORR: percentage of participants with a complete or partial response
    • Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm.
    • Partial Response (PR): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.

Secondary Outcome Measures :
  1. Clinical Benefit Rate (CBR) [ Time Frame: At 6 weeks ]
    • CBR is defined as the percentage of patients who have achieved responses (complete or partial) or stable disease.
    • Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm.
    • Partial Response (PR): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.
    • Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study.

  2. Toxicity and Tolerability as Measured by NCI-CTCAE Version 5.0 [ Time Frame: Through 30 days after completion of treatment (estimated to be 4 months) ]
    -Toxicity and tolerability will be measured by all immune-related and serious adverse events

  3. Overall Survival (OS) [ Time Frame: Through 2 years after completion of treatment (estimated to be 27 months) ]
  4. Progression-free Survival (PFS) [ Time Frame: Through 2 years after completion of treatment (estimated to be 27 months) ]
    -PFS is defined as the duration of time from start of treatment to time of progression or death, whichever occurs first.
