FDA Approves Ipsen’s Pancreatic Cancer Drug
FDA has approved an Ipsen Biopharmaceuticals NDA for Onivyde (irinotecan liposome) for use in combination with oxaliplatin, fluorouracil, and leucovorin for first-line treatment of metastatic pancreatic adenocarcinoma.
Approval was based on data from the company’s NAPOLI 3 trial (NCT04083235), a large-scale study involving 770 patients who had not previously undergone chemotherapy for metastatic pancreatic adenocarcinoma, according to an agency release. The trial compared the efficacy of the newly approved regimen, referred to as NALIRIFOX, with the standard gemcitabine plus Nab-paclitaxel (Gem+NabP) treatment.
Data from from NAPOLI 3 showed evidence of the superiority of NALIRIFOX over the Gem+NabP arm. The agency says that the primary efficacy measure, overall survival (OS), showed a statistically significant improvement with a median OS of 11.1 months for patients on NALIRIFOX compared to 9.2 months for those on Gem+NabP. Similarly, progression-free survival (PFS) was markedly extended in the NALIRIFOX group, with a median PFS of 7.4 months compared to 5.6 months in the Gem+NabP group, it says.
On the safety side, FDA says the most common adverse reactions observed (greater than or equal to 20% and a significant difference between arms) included diarrhea, fatigue, nausea, vomiting, decreased appetite, abdominal pain, mucosal inflammation, constipation, and decreased weight. Furthermore, notable laboratory abnormalities (Grade 3 or 4) associated with NALIRIFOX included decreased neutrophils, potassium, lymphocyte counts, and hemoglobin levels.
