      P2.01-014 - ABOUND.PS2: Safety and Efficacy of Nab-Paclitaxel–Based Therapy in Patients with NSCLC and ECOG PS 2 (ID 8186)

      • Abstract

      Background:
      Patients with advanced NSCLC with poor ECOG PS can benefit from platinum-based doublet chemotherapy, although limited data exist from recent, randomized prospective trials. ABOUND.PS2 evaluated the safety and efficacy of nab-paclitaxel/carboplatin induction followed by nab-paclitaxel monotherapy in patients with advanced NSCLC and ECOG PS 2.

      Method:
      Chemotherapy-naive patients with histologically/cytologically confirmed stage IIIB/IV NSCLC and ECOG PS 2 received 4 cycles of nab-paclitaxel 100 mg/m[2] on days 1 and 8 plus carboplatin AUC 5 on day 1 q3w. Patients not progressing could receive monotherapy with nab-paclitaxel 100 mg/m[2] on days 1 and 8 q3w until progression or unacceptable toxicity. Primary endpoint: percentage of patients discontinuing within the first 4 cycles due to treatment-emergent adverse events (TEAEs). Other endpoints: progression-free survival (PFS), disease control rate (DCR), overall survival (OS), overall response rate (ORR), and quality of life (QoL) by Lung Cancer Symptom Score (LCSS).

      Result:
      Forty patients were treated. Median age was 67.5 years, 60.0% were male, 92.5% were white, and 62.5% had nonsquamous histology. During induction, 11 of 40 patients (28%) discontinued due to TEAEs (primary endpoint). In total, 16 of 40 patients (40.0%) received nab-paclitaxel as monotherapy. In all treated patients, the median percentage of per-protocol dose of nab-paclitaxel was 78.3% and the median nab-paclitaxel dose intensity was 52.2 mg/m[2]/week (planned, 66.7 mg/m[2]/week). See table for additional safety, efficacy, and QoL results.

      Conclusion:
      These results support the role of this nab-paclitaxel–based regimen in patients with NSCLC and ECOG PS 2. The regimen was well tolerated and appears to have resulted in a clinically meaningful improvement in QoL. Compared with historical data, this regimen is active in patients with stage IIIB/IV NSCLC and ECOG PS 2. NCT02289456
