Bevacizumab in combination with platinum-based chemotherapy is associated with increased survival outcomes compared to chemotherapy alone in patients with non-squamous metastatic non-small cell lung cancer (mNSCLC). The objective of this study was to estimate potential economic benefits from a societal perspective in patients returning to work when treated with bevacizumab-based combination therapy. These economic benefits were assessed with respect to reduced productivity losses and described in terms of per patient cost savings. The analysis was conducted for France, Germany, Italy and Spain. Clinical outcomes in terms of progression-free survival (PFS) were based on two phase III clinical trials (E4599 and AVAiL) comparing bevacizumab + chemotherapy vs. chemotherapy alone. Potential cost savings due to reduction in productivity losses were assessed in progression-free patients who return back to work (human capital approach). It was assumed that 20% of all progression-free patients with performance status 0 or 1 and below 55 years of age would return back to work after the induction therapy maintaining their prior employment status (60% part-time, 40% full-time). Savings were calculated over 1 and 1.5 year time horizons. Mean savings, per progression-free patient ranged from 12,401 euro in Spain at year 1 to 39,001 euro in France at year 1.5. Respective findings proved to be fairly sensitive to the change of employment patterns and labour costs. This analysis shows that bevacizumab-based treatment can result in substantial cost savings in progression-free patients with mNSCLC.
