A Study of Atezolizumab in Combination With Carboplatin Plus (+) Paclitaxel With or Without Bevacizumab Compared With Carboplatin+Paclitaxel+Bevacizumab in Participants With Stage IV Non-Squamous Non-Small Cell Lung Cancer (NSCLC)

This randomized, open-label study evaluated the safety and efficacy of atezolizumab (an engineered anti-programmed death-ligand 1 [PD-L1] antibody) in combination with carboplatin+paclitaxel with or without bevacizumab compared with treatment with carboplatin+paclitaxel+bevacizumab in chemotherapy-naïve participants with Stage IV non-squamous NSCLC. Participants were randomized in a 1:1:1 ratio to Arm A (Atezolizumab+Carboplatin+Paclitaxel), Arm B (Atezolizumab+Carboplatin+Paclitaxel+Bevacizumab), or Arm C (Carboplatin+Paclitaxel+Bevacizumab).

  14. Time to Deterioration (TTD) in Patient-Reported Lung Cancer Symptoms Determined by European Organization for Research and Treatment of Cancer (EORTC) Quality-of-Life Questionnaire-Core 30 (QLQ-C30) Score

    Time frame: Baseline up to approximately 29 months

    EORTC QLQ-C30 is a validated & reliable self-report measure (Aaronson et al.1993;Fitzsimmons et al.1999) that consists of 30 questions that assess 5 aspects of patient functioning (physical,emotional,role, cognitive,and social), 3 symptom scales (fatigue,nausea & vomiting, pain),global health/quality of life,and six single items (dyspnea,insomnia, appetite loss,constipation,diarrhea, and financial difficulties). EORTC QLQ-C30 is scored according to the EORTC scoring manual (Fayers et al. 2001). All EORTC scales and single-item measures are linearly transformed so that each score has a range of 0-100. A high score for a functional/global health status scale represents a high or healthy level of functioning/HRQoL (Health-Related Quality of Life);however a high score for a symptom scale or item represents a high level of symptomatology or problems. A ≥10-point change in the symptoms subscale score is perceived by patients as clinically significant (Osoba et al.1998).

  15. TTD in Patient-Reported Lung Cancer Symptoms as Determined by EORTC Quality-of-Life Questionnaire-Core Lung Cancer Module 13 (QLQ-LC13) Score

    Time frame: Baseline up to approximately 29 months

    QLQ-LC13 Quality-of-Life Questionnaire Lung Cancer Module incorporates one multiple-item scale to assess dyspnea and a series of single items assessing pain, coughing, sore mouth, dysphagia, peripheral neuropathy, alopecia, and hemoptysis. The EORTC QLQ-LC13 is scored according to the EORTC scoring manual (Fayers et al. 2001). All EORTC scales and single-item measures are linearly transformed so that each score has a range of 0-100. A high score for a functional/global health status scale represents a high or healthy level of functioning/HRQoL (Health-Related Quality of Life); however, a high score for a symptom scale or item represents a high level of symptomatology or problems. A ≥10-point change in the symptoms subscale score is perceived by patients as clinically significant (Osoba et al. 1998).

  16. Change From Baseline in Patient-Reported Lung Cancer Symptoms Score Using the Symptoms in Lung Cancer (SILC) Scale

    Time frame: Baseline up to approximately 29 months

    The SILC (Symptoms in Lung Cancer) scale was used to assess patient-reported severity of lung cancer symptoms (chest pain, dyspnea, and cough). The SILC scale is a 9-item content validated self-report measure of lung cancer symptoms. It measures severity of cough, dyspnea, and chest pain with a symptom severity score. The SILC questionnaire comprises three individual symptoms (dyspnea, cough, chest pain) and are scored at the individual symptom level, thus have a dyspnea score, chest pain score, and cough score. Each individual symptom score is calculated as the average of responses for the symptom items [e.g. Chest Pain Score=mean (item 1; item 2)]. An increase in score is suggestive of a worsening in symptomology (i.e. frequency or severity). A score change of ≥0.3 points for the dyspnea and cough symptom scores is considered to be clinically significant; whereas a score change of ≥0.5 points for the chest pain score is considered to be clinically significant.

  17. Percentage of Participants With Adverse Events

    Time frame: Baseline up to data cutoff date 7 December 2020 (up to approximately 68 months)

    Percentage of participants with at least one adverse event.

  18. Percentage of Participants With Anti-Therapeutic Antibodies (ATAs) to Atezolizumab

    Time frame: Baseline up to approximately 29 months

  19. Maximum Observed Serum Concentration (Cmax) of Atezolizumab in Arm A and Arm B

    Time frame: Day 1 of Cycle 1 and 3 (Cycle length=21 days)

    The predose samples will be collected on the same day of treatment administration. The infusion duration of atezolizumab will be of 30-60 minutes.

  20. Minimum Observed Serum Concentration (Cmin) of Atezolizumab Prior to Infusion in Arm A and Arm B

    Time frame: Day 21 of Cycles 1, 2 3, and 7 (Cycle length=21 days)

  21. Plasma Concentrations for Carboplatin in Arm A, Arm B, and Arm C

    Time frame: Predose (same day of treatment administration), 5-10 minutes before end of carboplatin infusion, 1 h after carboplatin infusion (infusion duration=15 to 30 minutes) on D1 of Cy1,3 (Cycle length=21 days)

  22. Plasma Concentrations for Paclitaxel in Arm A, Arm B, and Arm C

    Time frame: Predose (same day of treatment administration), 5-10 minutes before end of paclitaxel infusion, 1 h after paclitaxel infusion (infusion duration=3 h) on D1 of Cy1,3 (Cycle length=21 days)
