ABSTRACT: Background
In the NAPOLI-1 phase 3 trial, liposomal irinotecan (nal-IRI) +5-fluorouracil/leucovorin (5-FU/LV) significantly increased mPFS versus 5-FU/LV (3.1 vs. 1.5 months [unstratified HR = 0.56, p = 0.0001]) in patients with mPAC that progressed on prior gemcitabine-based therapy. This randomized phase 2 trial evaluated nal-IRI+5-FU/LV tolerability (Part 1), safety, and efficacy (Part 2; outcomes reported here) in Japanese patients with mPAC that progressed on gemcitabine-based therapy.Methods
Patients were randomized 1:1 and stratified by KPS (70 and 80 vs. ?90) and baseline albumin (?4.0 g/dl vs. <4.0 g/dl). Primary endpoint was PFS; secondary endpoints were ORR, DCR, OS, TTF, CA19-9 response, and QoL. The ITT population comprised all randomized patients.Results
Patient characteristics differed between nal-IRI+5-FU/LV (n = 40) and 5-FU/LV (n = 39) arms, including baseline hepatic lesions (63% vs. 51%), stage IV disease at diagnosis (78% vs. 51%), and post-study anticancer therapy (55% vs. 72%). Investigator-assessed mPFS increase with nal-IRI+5-FU/LV was clinically meaningful and statistically significant versus 5-FU/LV (2.7 vs. 1.5 months, HR = 0.60). Independently assessed mPFS showed similar trends (1.7 vs. 1.6 months, HR = 0.79). mOS was 6.3 months with nal-IRI+5-FU/LV and not reached with 5-FU/LV. ORR increased significantly with nal-IRI+5-FU/LV versus 5-FU/LV (18% vs. 0, rate difference 17.5). Commonly reported grade ?3 treatment-emergent AEs were decreased neutrophil count (37% vs. 3%), decreased white blood cell count (20% vs. 0), and diarrhea (17% vs. 3%).Conclusions
In conclusion, clinically meaningful and statistically significant gains in investigator-assessed PFS and ORR were observed with nal-IRI+5-FU/LV versus 5-FU/LV in Japanese patients, with no new or unexpected safety signals. (Clinicaltrials.gov ID: NCT02697058).
