Abstract
Purpose
Consolidation immunotherapy with the PD-L1 inhibitor durvalumab following concurrent chemoradiotherapy (cCRT) has shown a significant survival improvement and is now a standard of care in patients with unresectable stage III or non-operable non-small cell lung cancer (NSCLC).
Methods
In this early access program cohort, demographic, disease characteristics and safety data were collected for 576 patients from 188 centers, who received durvalumab 10 mg/kg intravenous infusion every 2 weeks, until disease progression or unacceptable toxicity or for a maximum of 12 months following cCRT. Durvalumab exposure data were available for 402 patients.
Results
Overall, 576 patients were included, 72.9% were men, median age 64.0 years, 52.3% had a stage IIIB disease. PD-L1 status captured in 445 (77%) patients was positive (48.1%), negative (32.6%), unknown (19.3%). At the end of cCRT, adverse events (AEs) all grade ≤ 2, were reported in 22.7% of patients, mainly esophagitis (6.3%). The main reasons of discontinuation were completion of the planned 12 months of consolidation treatment (42.1% patients), disease progression (28.6%) and adverse events (19.5%). Treatment completion was similar in PDL-1 positive and PDL-1 negative patients groups. 20.7% patients had a SAE drug reaction and 17.7% stopped treatment mainly due to SAE. ADR rate and early treatment discontinuation were higher in patients > 70 years old. Death due to AEs occurred in 7 patients, 2 had interstitial lung disease.
Conclusion
Safety data with durvalumab consolidation after cCRT in a large cohort of patients with stage III NSCLC are reported in this real-life cohort. Consistent data were reported both in the PD-L1 positive and PD-L1 negative NSCLC patients in daily practice.
