      P3.01-94 - Safety and Efficacy of First-Line Pemetrexed Versus Bevacizumab-Containing Regimens in Advanced Non-Small Cell Lung Cancer (ID 12179)

      • Abstract


      Previous trial data have documented the efficacy of first-line bevacizumab-based regimens, including bevacizumab-pemetrexed combinations in advanced non-small cell lung cancer (NSCLC). We herein aimed to further assess the safety and efficacy of pemetrexed monotherapy versus bevacizumab-containing or other chemotherapy regimens in a real-world NSCLC population.

      The medical records of 753 patients with advanced-stage non-squamous NSCLC, treated with bevacizumab-based regimens, pemetrexed monotherapy, or other treatments, as first-line therapy, were retrospectively reviewed and analyzed for efficacy and safety endpoints.

      The bevacizumab-based group had the highest percentage of partial response/PR (32.3% vs 22.8% for pemetrexed and 20.0% for other treatments) and a significantly lower incidence of progressive disease/PD (35.92%, 30.17%, and 50.48%, for pemetrexed, bevacizumab-based, and other, respectively; p < 0.0001). Bevacizumab-based regimens achieved a better overall survival (OS) rate (measured at the end of treatment) (pemetrexed 29.6%, bevacizumab-based 35.7%, and other treatments 8.9%; p < 0.0001). However, median OS was not improved (10 months, 12 months, and 13 months for pemetrexed, bevacizumab-based, and other treatments, respectively; p=0.007). A significantly higher incidence of cough (p = 0.001) and hemoptysis (p < 0.0001) in the bevacizumab-based arm, pain in the pemetrexed arm (p = 0.007), and alopecia in the other treatments arm (p < 0.0001) was observed during treatment. A significantly higher incidence of hemoptysis in the bevacizumab-based arm (p < 0.0001) and alopecia in the other treatments arm (p < 0.0001) was seen at the end of first-line treatment.

      Bevacizumab-based regimens resulted in improved treatment response and short-term survival rate, but not in improved OS. An increased, albeit acceptable, toxicity was also observed among bevacizumab-treated patients as compared to those treated with pemetrexed monotherapy.
