Phase 3, PACIFIC
Patient-reported outcomes of the phase 3 PACIFIC trial indicated that durvalumab did not have a detrimental impact on patient quality of life (QoL) compared with placebo, irrespective of whether patients experienced grade ≥2 pneumonitis.

The phase 3 PACIFIC trial (NCT02125461) demonstrated that maintenance therapy with the immune checkpoint inhibitor durvalumab after completion of concurrent chemoradiotherapy (CRT) significantly improves progression-free and 5-year overall survival in patients with unresectable non-small cell lung cancer (NSCLC) [1,2]. Any-grade pneumonitis (including radiation-pneumonitis) was among the most common adverse events in PACIFIC, occurring in 33.9% and 24.8% of participants on durvalumab and placebo, respectively [2]. Pneumonitis predominantly occurred with low-grade severity, and a prior exploratory analysis from PACIFIC suggested treatment benefit with durvalumab was maintained regardless of the occurrence of pneumonitis [3]. A post-hoc analysis of the PACIFIC trial investigated whether the occurrence of grade ≥2 pneumonitis during the study impacted the tolerability of durvalumab from a patient perspective. Prof. Rina Hui (University of Sydney, Australia) presented the results [4].

Patient-reported outcomes were assessed with EORTC QLQ-C30 and QLQ-LC13 in 94 and 33 participants with grade ≥2 pneumonitis originally randomised to the durvalumab and placebo arm, respectively. Grade ≥2 pneumonitis typically occurred within 3 months of starting durvalumab or placebo. In both treatment arms, no clinically meaningful changes in patient-reported outcome scores were observed at weeks 16 or 24 from the start of treatment, regardless of whether participants experienced grade ≥2 pneumonitis (see Figure). In addition, time to deterioration was longer with durvalumab compared with placebo, which remained the case when adjusting for the occurrence of grade ≥2 pneumonitis.

“These results indicate that the possibility of grade ≥2 pneumonitis should not deter physicians from using the PACIFIC regime in eligible patients,” concluded Prof. Hui. “Treatment guidelines should be followed if this adverse event occurs.”
