Abstract 1519P

Background

In the phase-3 NAPOLI-1 trial (NCT01494506), liposomal irinotecan (nal-IRI) with 5-fluorouracil/leucovorin (5-FU/LV) improved survival outcomes in mPDAC patients pre-treated with gemcitabine-based regimens. However, real-world data on clinical benefits and safety are scarce. This study gathered real-world evidence on patients who survived ≥1 year after initiation of nal-IRI following treatment with a gemcitabine-based regimen.

Methods

This retrospective non-interventional study was conducted in Austria, Belgium, Germany, Japan, and South Korea. Data were collected from mPDAC patients who received ≥1 nal-IRI/5-FU/LV after a gemcitabine-based chemotherapy from January 2018 to December 2021 and surviving >1 year after initiation of the combination. Descriptive analyses, treatment patterns summaries, and overall survival (OS) determination via Kaplan-Meier method were conducted.

Results

Of the 163 patients analyzed, 131 (80.4%) were deceased and 32 (19.6%) alive. Ten (6.1%) patients initiated nal-IRI in 1L, 123 (75.5%) in 2L, and 30 (18.4%) in ≥3L. The median number of nal-IRI cycles received was 14 (min-max: 1-108). The median treatment duration from initiation to end of treatment was 8.4 (min-max: 0-45) months. At data cut-off, 139 (85.3%) discontinued nal-IRI, with 98 (70.5%) of them due to progression. Overall, 44 (27.0%) experienced grade 3/4 adverse drug reactions. Median OS from mPDAC diagnosis and nal-IRI initiation was 34.3 (CI 30.4-37.5) and 21.0 (CI 19.0-23.7) months, respectively. Table: 1519P

Conclusions

In mPDAC, subgroups of patients with favorable OS exist, but are poorly understood. This real-world cohort had a median OS comparable to that of long-term treated NAPOLI-1 survivors, yet older with more prior lines of therapy. This real-world cohort will allow for further analyses exploring the underlying mechanisms of this population of long-term survivors.
