    • Abstract

    Background:
    ABOUND.PS2 evaluated nab-paclitaxel/carboplatin induction followed by nab-paclitaxel monotherapy in patients with advanced NSCLC and ECOG PS 2. Concordance between patient- and physician-reported PS as well as change in PS with chemotherapy were assessed longitudinally.
    
    Method:
    Chemotherapy-naive patients with histologically/cytologically confirmed stage IIIB/IV NSCLC and ECOG PS 2 received 4 cycles of nab-paclitaxel 100 mg/m[2] on days 1 and 8 plus carboplatin AUC 5 on day 1 q3w. Patients not progressing could receive monotherapy with nab-paclitaxel 100 mg/m[2] on days 1 and 8 q3w until progression or unacceptable toxicity. Primary endpoint was the percentage of patients discontinuing within the first 4 cycles due to treatment-emergent adverse events. ECOG PS was assessed by patients on day 1 of each cycle and at treatment discontinuation, and ECOG PS and spirometry were assessed by physicians at screening, on day 1 of each cycle, and at treatment discontinuation.
    
    Result:
    Forty patients were treated. Baseline ECOG PS was reported as 2 by 48% and 95% of patients and physicians, respectively. Only 53% of patients rated their ECOG PS the same as the physician at cycle 1 day 1. For patients with both pre- and post-treatment ECOG assessments, 14 of 33 patients (42%) and 12 of 38 physicians (32%) reported an improvement from baseline at least once during treatment (Figure). At baseline, physicians believed that ECOG PS would be reversible with treatment in the majority of patients (80%). Mean FEV1 was 1.29 L and mean PEF was 2.66 L/s at baseline; exploratory investigations of spirometry data indicate that lung function (FEV1 and PEF) remained stable over the course of treatment.
    
    Conclusion:
    These results from the ABOUND.PS2 study suggest that patient-reported PS assessments may differ from physician assessments. Improvements in ECOG PS were reported by both patients and physicians during treatment. NCT02289456Figure 1
