MO06.10 - Phase II study of bevacizumab, cisplatin and docetaxel plus maintenance bevacizumab as first line treatment for patients with advanced non-small cell lung cancer (n-Sq NSCLC) combined with exploratory analysis of circulating cells (CEC): Thoracic Oncology Research Group (TORG)1016 (ID 1211)
16:15 - 17:45 | Author(s): T. Kaburagi
Bevacizumab has been shown to amplify efficacy against n-Sq NSCLC in combination with platinum doublet, especially taxane including regimens. Docetaxel is one of best taxane composition combined with cisplatin for first line treatment for NSCLC, and known to have anti-angiogenic effect and may act synergistically with VEGF inhibiting agent. The object of this study was to assess the efficacy and safety of bevacizumab, cisplatin and docetaxel combination treatment in patients with chemonaive n-Sq NSCLC patients. (Trial Registry: UMIN 000004368)
Eligible patients had advanced or recurrent n-Sq NSCLC with no prior chemotherapy. Patients having brain metastasis or history of hemoptysis were ineligible. Patients received 4 cycles of docetaxel (60mg/m), cisplatin (80mg/m) and bevacizumab (15mg/kg) on day1 every 3 weeks followed by Bev alone as maintenance every 3 weeks until disease progression or unacceptable toxicity. The primary endpoint was response rate (RR) and planned sample size of this phase II study was 47 patients (Simon's two-stage minimax design). We measured circulating endothelial cells (CEC) count day1 and 8 of first cycle for exploratory analysis of efficacy and safety prediction.
From Oct 2010 to Apr 2012, 47 patients (28 males/ 19 females, median age, 61 years, 39-73) were enrolled. Stage IIIB/IV/recurrent: 5/39/3, ECOG PS 0/1: 31/16. All patients were adenocarcinoma, EGFR status: mutated/wild/unknown: 13/31/3. Bevacizumab maintenance were administered in 87% (41/47) of the patients and 9 was median number of delivered course, 4 course of induction and 5 course of maintenance. Dose reduction was required in 28% (13/47) of the patients. Thirty-five partial responses and 11 stable diseases were observed among 47 patients, yielding a RR of 74.5% (95% confidence interval: 59.7-86.1%) and disease control rate of 97.9% (88.7-99.9%), respectively. The median progression free survival duration in the patients was 9.0 (7.0-11.3) months. Grade 3/4 leukopenia, neutropenia, hypertension, nausea and febrile neutropenia were observed in 60, 96, 47, 13 and 9% of the patients, respectively. Alveolar hemorrhage (Grade 5) after 4 cycle occurred in one patient.
Bevacizumab, cisplatin and docetaxel combination followed by bevacizumab maintenance treatment was highly effective in patients with n-Sq NSCLC, with acceptable toxicity. Exploratory analysis of CEC is ongoing and will be presented.
