P2.07-032 - Outcomes of Nivolumab in Metastatic NSCLC Patients via the Access Program Across Multiple Tertiary Oncology Centres. (ID 9298)

- Abstract
Background:
Immune checkpoint inhibitors are the standard of care for non-small cell lung cancer (NSCLC) patients following first line therapy. There is limited information available on the outcomes of patients receiving these therapies for NSCLC outside of a clinical trial.
Method:
We retrospectively collected data from patients who received Nivolumab for advanced NSCLC on the Bristol-Myers Squibb (BMS) Access Program across four tertiary oncology institutions in Brisbane, Australia, to analyse their outcomes in a real-world setting, and compare these outcomes to those in Phase III randomised clinical trials.
Result:
85 patients were enrolled to this Ethics Committee approved audit - 32 females (37.6%); 53 males (62.4%); 54, PS 0-1 (63.5%); 30, PS 2-3 (35.3%); median age 67 yrs (range 42-84). 84 patients were evaluable for progression. 20% (17/84) of patients had a radiological partial response (PR) during the course of their treatment, and an additional 22.4% (19/84) patients had stable disease (SD) as their best response. In PS 0-1, 24% (13/54) had a PR, compared with only 10% (3/30) in PS 2-3 patients. The overall median progression-free survival (PFS) was 1.8 months, being 2.7 months in PS 0-1 versus 1.2 months in PS 2-3 patients. Median overall survival (OS) was 5.9 months; 6.5 months in PS 0-1 versus 2.3 months in PS 2-3 patients. Median OS for adenocarcinoma was 6.2 months, versus 4.7 months for squamous cell carcinoma. At 12 months after initiation of nivolumab 34% of patients were alive; 44% PS 0-1 versus 16% PS 2-3 patients. Grade 3 or 4 treatment related adverse events were observed in 10% of patients. Analysis of the prognostic relevance of routine haematological and biochemical parameters is ongoing.
Conclusion:
Nivolumab has clinically significant long term benefits in the treatment of relapsed NSCLC with 12 month survival rates in keeping with clinical trials in PS 0-1 patients. The development of predictive biomarkers remains central to identifying those patients, particularly with poor performance, most likely to benefit from immune checkpoint inhibitors.
