A Study of Atezolizumab (Anti-Programmed Death-Ligand 1 [PD-L1] Antibody) in Combination With Carboplatin Plus (+) Nab-Paclitaxel Compared With Carboplatin + Nab-Paclitaxel in Participants With Non-Squamous Non-Small Cell Lung Cancer (NSCLC) (IMpower130)

Overview

About this study

This randomized Phase III, multicenter, open-label study is designed to evaluate the safety and efficacy of atezolizumab in combination with carboplatin + nab-paclitaxel compared with treatment with carboplatin + nab-paclitaxel in chemotherapy-naive participants with Stage IV non-squamous NSCLC. Participants will be randomized in a 2:1 ratio to Arm A (Atezolizumab + Nab-Paclitaxel + Carboplatin) or Arm B (Nab-Paclitaxel + Carboplatin).

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

  • Signed Informed Consent Form.
  • Male or female, 18 years of age or older.
  • ECOG performance status of 0 or 1.
  • Histologically or cytologically confirmed, Stage IV non-squamous NSCLC (per the Union Internationale contre le Cancer/American Joint Committee on Cancer staging system, 7th edition; Detterbeck et al. 2009).
    • Patients with tumors of mixed histology (i.e., squamous and non-squamous) are eligible if the major histological component appears to be non-squamous.
  • No prior treatment for Stage IV non-squamous NSCLC.
    • Patients with a sensitizing mutation in the EGFR gene must have experienced disease progression (during or after treatment) or intolerance to treatment with one or more EGFR TKIs, such as erlotinib, gefitinib, or another EGFR TKI appropriate for the treatment of EGFR-mutant NSCLC.
    • Patients known to have an ALK fusion oncogene must have experienced disease progression (during or after treatment) or intolerance to treatment with one or more ALK inhibitors (e.g., crizotinib) appropriate for the treatment of NSCLC in patients having an ALK fusion oncogene.
    • Patients with unknown EGFR and ALK status require test results at screening.
    • ALK and/or EGFR may be assessed locally or at a central laboratory.
    • Patients who have received prior neo-adjuvant, adjuvant chemotherapy, radiotherapy, or chemoradiotherapy with curative intent for non-metastatic disease must have experienced a treatment-free interval of at least 6 months from randomization since the last chemotherapy, radiotherapy, or chemoradiotherapy cycle.
  • 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.
  • Known PD-L1 tumor status as determined by an IHC assay performed by a central laboratory on previously obtained archival tumor tissue or tissue obtained from a biopsy at screening.
    • A representative formalin-fixed paraffin-embedded (FFPE) tumor specimen in paraffin block (preferred) or 15 or more unstained, freshly cut, serial sections on slides from an FFPE tumor specimen is required for participation in this study.
    • If fewer than 15 slides are available at baseline (but no fewer than 10), the patient may still be eligible, upon discussion with the Medical Monitor. This specimen must be accompanied by the associated pathology report.
    • Fine-needle aspiration (defined as samples that do not preserve tissue architecture and yield cell suspension and/or cell smears), brushing, cell pellet specimens (e.g., from pleural effusion, and lavage samples) are not acceptable.
    • Tumor tissue from bone metastases that is subject to decalcification is not acceptable.
    • For core-needle biopsy specimens, preferably at least three cores embedded in a single paraffin block, should be submitted for evaluation.
  • Measurable disease, as defined by RECIST v1.1
    • Previously irradiated lesions can only be considered as measurable disease if disease progression has been unequivocally documented at that site since radiation and the previously irradiated lesion is not the only site of disease.
  • Adequate hematologic and end organ function, defined by the following laboratory results obtained within 14 days prior to randomization:
    • ANC ≥ 1500 cells/µL without granulocyte colony-stimulating factor support;
    • Lymphocyte count ≥ 500/µL;
    • Platelet count ≥ 100,000/µL without transfusion;
    • Hemoglobin ≥ 9.0 g/dL;
    • Patients may be transfused to meet this criterion;
    • INR or aPTT ≤ 1.5 x upper limit of normal (ULN).
      • This applies only to patients who are not receiving therapeutic anticoagulation; patients receiving therapeutic anticoagulation should be on a stable dose.
    • AST, ALT, and alkaline phosphatase ≤ 2.5 x ULN, with the following exceptions:
    • Patients with documented liver metastases: AST and/or ALT ≤ 5 x ULN;
    • Patients with documented liver or bone metastases: alkaline phosphatase ≤ 5 x ULN;
    • Serum bilirubin ≤ 1.25 x ULN;
    • Patients with known Gilbert disease who have serum bilirubin level ≤ 3 x ULN may be enrolled;
    • Serum creatinine ≤ 1.5 x ULN.
  • For female patients of childbearing potential agreement (by patient and/or partner) to use a highly effective form(s) of contraception that results in a low failure rate (< 1% per year) when used consistently and correctly, and to continue its use for 5 months after the last dose of atezolizumab or for 30 days after the last dose of nab-paclitaxel, whichever is later. Women must refrain from donating eggs during this same period. For male patients with female partners of childbearing potential, agreement (by patient and/or partner) to use a highly effective form(s) of contraception that results in a low failure rate (< 1% per year) when used consistently and correctly, and to continue its use for 6 months after the last dose of nab-paclitaxel and/or carboplatin, whichever is later. Such methods include: combined (estrogen and progestogen containing) hormonal contraception, progestogen-only hormonal contraception associated with inhibition of ovulation together with another additional barrier method always containing a spermicide, intrauterine device (IUD), intrauterine hormone-releasing system (IUS), bilateral tubal occlusion or vasectomized partner (on the understanding that this is the only one partner during the whole study duration), and sexual abstinence. Male patients should not donate sperm during this study and for at least 6 months after the last dose of nab-paclitaxel and/or carboplatin, whichever is later.
  • Oral contraception should always be combined with an additional contraceptive method because of a potential interaction with the study drug. The same rules are valid for male patients involved in this clinical study if they have a partner of childbearing potential. Male patients must always use a condom.
  • Women who are not postmenopausal (≥ 12 months of non-therapy-induced amenorrhea) or surgically sterile must have a negative serum pregnancy test result within 14 days prior to initiation of study drug.
