Phase II Randomized Trial of Carboplatin+Pemetrexed+Bevacizumab+/- Atezolizumab in Stage IV NSCLC

While cigarette smoking remains the primary cause of most lung cancer cases, lung carcinoma in never smokers account for nearly 20 percent of cases. Never smokers with lung cancer typically present with different molecular profiles from that of smokers, which results in prognostic and therapeutic implications. Molecular changes in NSCLC that have therapeutic significance include mutations in the epidermal growth factor receptor (EGFR) and rearrangements in the anaplastic lymphoma kinase (ALK) gene. These driver mutations typically are present in lung tumors found in never or light smokers.

The addition of bevacizumab to carboplatin and paclitaxel in first-line treatment of non-squamous NSCLC showed improved survival compared to carboplatin and paclitaxel alone, 12.3 vs. 10.3 months respectively. Results from the POINTBREAK trial demonstrated that carboplatin + pemetrexed + bevacizumab is an alternative option to carboplatin + paclitaxel + bevacizumab, with comparable survival but less toxicity. In recent years, immunotherapy has emerged as a form of treatment that can lead to robust responses in a subset of patients. The PD-1 inhibitor nivolumab and the PD-L1 inhibitor atezolizumab have shown prolonged survival in comparison to docetaxel in patients who previously progressed with chemotherapy, irrespective of PD-L1 expression. Thus, this study combines immunotherapeutic agent atezolozumab with an ant-angiogenic agent, bevacizumab, and double platinum therapy (carboplatin and pemetrexed).

Eligibility


Inclusion Criteria:

   - Patients must have histologically or cytologically confirmed stage IV non-squamous
   non-small cell lung cancer

   - Patients must either have tumors that harbor an EGFR mutation in exon 19 or exon 21,
   or must be never smoker wild-types. Never smoker wild-types are defined as patients
   with tumors without an ALK or ROS1 rearrangement, and are not harboring any EGFR
   mutation (this includes exons 19 or 21, exon 20, and any other rare EGFR mutations).
   Never smoker wild-type patients must have smoked less than 100 cigarettes in a
   lifetime. Patients with an EGFR mutation in exon 19 or 21 may be included irrespective
   of their smoking history. If tissue-based testing for EGFR mutation status is not
   available, blood-based EGFR testing that confirms presence of a mutation in exon 19 or
   21 is acceptable, and these patients may be included in the study

   - Patients must have measurable disease by CT or MRI, defined as at least one lesion
   that can be accurately measured in at least one dimension in accordance with RECIST
   criteria v 1.1

   - Patients with tumors that harbor an EGFR exon 19 or exon 21 mutation must have
   received prior treatments with one or more TKIs. A washout period of at least 2 weeks
   is required to begin treatment in this trial. Patients who are never smoker wild-types
   must be treatment naïve

   - All patients must be chemotherapy, VEGF therapy, and immunotherapy naive, with the
   exception of prior oral TKIs which are required for EGFR mutated patients. The number
   of prior oral TKIs and duration of use is neither specified nor limited.

   - Patients with a history of treated asymptomatic CNS metastases are eligible, provided
   they meet all of the following criteria:

      - Only supratentorial and cerebellar metastases allowed (i.e., no metastases to
      midbrain, pons, medulla or spinal cord)

      - No ongoing requirement for corticosteroids as therapy for CNS disease

      - No stereotactic radiation within 7 days or whole-brain radiation within 14 days
      prior to randomization

      - No evidence of interim progression between the completion of CNS-directed therapy
      and the screening radiographic study

Patients with new asymptomatic CNS metastases detected at the screening scan must receive
radiation therapy and/or surgery for CNS metastases. Following treatment, these patients
may then be eligible without the need for an additional brain scan prior to randomization,
if all other criteria are met

   - Age > 18 years

   - ECOG performance status 0 or 1

   - Patients must have normal organ and marrow function as defined below. The use of G-CSF
   should follow standard recommendations and physician discretion. If blood transfusion
   is performed for achieving hemoglobin levels, the levels should stay at ≥ 9.0 mg/ml
   for at least a week after transfusion.

institutional normal limits, or up to 5 times institutional normal limits if the patient
has liver metastases Creatinine OR Creatinine clearance ≤1.5 X ULN, OR > 40 Ml/min/1.73 m2
for patients with creatinine levels above institutional normal as per Cockcroft-Gault
formula International Normalized Ratio (INR) or Prothrombin Time (PT) ≤1.5 X ULN unless
subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range

total T3 or free T4 are within normal limits.

   - Patients on full-dose anticoagulation must be on a stable dose (minimum duration 14
   days) of oral anticoagulant or low molecular weight heparin (LMWH). If receiving
   warfarin, the patient must have an INR ≤3.0. For heparin and LMWH there should be no
   clinically significant active bleeding (with no bleeding within 14 days prior to first
   dose of protocol therapy) or pathological condition present that carries a high risk
   of bleeding (for example, tumor involving major vessels or known varices).

   biopsy specimen before the start of treatment. Any available archival tissue will also
   be collected.

   - Urinary protein must be ≤1+ on dipstick or routine urinalysis (UA; if urine dipstick
   or routine analysis is ≥2+, a 24 hour urine collection for protein must demonstrate

from the effects of radiation. There is no required minimum recovery period.

Asymptomatic metastatic lesions whose further growth would likely cause functional deficits
or intractable pain (e.g., epidural metastasis that is not currently associated with spinal
cord compression) should be considered for locoregional therapy, if appropriate, prior to
randomization.
