Zusammenfassung: | Bevacizumab with platinum doublet therapy including paclitaxel + carboplatin improves the survival of patients with non-squamous non-small cell lung cancer. However, in a previous trial (CA031), paclitaxel + carboplatin led to Grade > 3 neutropenia in a Japanese population. Nanoparticle albumin-bound paclitaxel exhibits an improved toxicity profile. We evaluated the safety, dosage and response rate of the nanoparticle albumin-bound paclitaxel + carboplatin + bevacizumab combination in a Japanese population.
Chemotherapy-naive patients with advanced non-squamous non-small cell lung cancer were included. The dosage schedule was established in the Phase I trial as follows: 4-6 cycles of carboplatin (area under the concentration-time curve = 6 on Day 1) + nanoparticle albumin-bound paclitaxel (100 mg/m2 on Days 1, 8 and 15) + bevacizumab (15 mg/kg on Day 1), followed by maintenance therapy (nanoparticle albumin-bound paclitaxel + bevacizumab). The response rate and presence of adverse effects were evaluated in the Phase II trial.
The overall response rate was 56.5% (90% confidence interval: 44.5-68.5), and 93% of patients (43/46) showed tumor shrinkage or maintained a stable disease course. The primary endpoint was achieved. At the median follow-up duration of 42 months, the median overall survival was 18.9 (range: 10.5-32.4) months. The most frequently observed Grade ≥ 3 adverse effects were neutropenia (72%), leukopenia (50%) and anemia (30%).
All adverse effects were manageable and none resulted in patient death. In conclusion, the nanoparticle albumin-bound paclitaxel + carboplatin + bevacizumab combination is favorable and well tolerated in Japanese patients as first-line treatment for advanced non-squamous non-small cell lung cancer. |
