      Chemotherapy may enhance immunotherapeutic effects by causing tumor antigen release, which primes the immune system to kill tumor cells. Early clinical data on nab-paclitaxel + carboplatin in combination with immune checkpoint inhibitors (ICI) demonstrated promising activity without compounding toxicities in patients with non-small cell lung cancer (NSCLC). ABOUND.2L+ evaluated nab-paclitaxel–based regimens in previously treated patients with advanced NSCLC. Here we report the efficacy and safety of nab-paclitaxel + durvalumab as second/third-line treatment.

      Patients with advanced NSCLC were assigned to receive second/third-line (immunotherapy allowed in prior line, including platinum doublet combination) nab-paclitaxel 100 mg/m[2] on days 1 and 8 + durvalumab 1125 mg on day 15, in 21-day cycles, administered until unacceptable toxicity/progression per immune-related RECIST v1.1. Primary endpoint is progression-free survival (PFS). Secondary endpoints are overall survival (OS), overall response rate (ORR), disease control rate (DCR), and safety.

      Seventy-nine patients were enrolled. Median age was 63 years, 68% of patients were male, 23% had Eastern Cooperative Oncology Group performance status of 0, and 70% had nonsquamous NSCLC; 11% of patients received prior ICIs. Median PFS (Table) and OS were 4.5 (3.4-5.8) months and NE (7.3-NE). ORR was 27% (1 complete response) and DCR was 71%. Grade 3/4 treatment-emergent adverse events of special interest occurring in ≥ 5% of patients included neutropenia (6%) and dyspnea (5%); grade 3/4 peripheral neuropathy and anemia each occurred in 4% of patients. Median treatment duration was 24 weeks; median number of treatment cycles was 7. For nab-paclitaxel and durvalumab, median dose intensities were 59.05 mg/m[2]/week and 326.61 mg/week, respectively; median percentages of per-protocol dose were 88.58% and 87.10%.

      The combination of durvalumab with nab-paclitaxel demonstrated antitumor activity with manageable toxicity in the second/third-line setting. Further details will be presented. NCT02250326
