Incorporation of bevacizumab (B) and erlotinib (Er) with induction (I) and concurrent (C) carboplatin (Cb)/paclitaxel (P) and 74 Gy of thoracic radiotherapy in stage III non-small cell lung cancer (NSCLC)

Abstract

7517 Background: Therapies directed at both the epidermal growth factor receptor (EGFR) and the vascular endothelial growth factor (VEGF) pathways have been shown to improve survival in NSCLC and also have radiosensitizing properties. Methods: Pts receive I Cb (AUC 6), P (225 mg/m2) and B (15 mg/kg) on d1 and 22. PET scans are done pre- and post-I. On day 43, pts receive weekly Cb (AUC 2 x 7) and P (45 mg/m2 x 7) with 74 Gy (2 Gy/d) of thoracic conformal radiotherapy. Cohort I (n=5) received B at 10 mg/kg q2wks during C therapy. Cohorts II and III (both n=5) received the same dose of B as in cohort I but also received Er at 100 mg and 150 mg po Tuesday - Friday of each week of C therapy, respectively. The primary endpoint is PFS at 1 year. All histologies are allowed including squamous (SQ) (an early stopping rule is in place for pulmonary hemorrhagic complications in the SQ). Results: Thus far, 20 PS 0–1 pts have been accrued (med age 62 yrs, range 41–74, 12 non-squamous, 8 squamous, 12 IIIA, 8 IIIB). 18...
