N2 - Background: PEP02, also known as MM-398, is a novel nanoliposomal irinotecan that has improved pharmacokinetics and tumour bio-distribution of the free drug. This phase 2 study evaluated PEP02 monotherapy as second-line treatment for pancreatic cancer. Methods: Patients who had metastatic pancreatic adenocarcinoma, Karnofsky performance status ≥70, and had progressed following gemcitabine-based therapy were eligible. Intravenous injection of PEP02 120 mg m-2 was given every 3 weeks. Simon 2-stage design was used. The primary objective was 3-month survival rate (OS 3-month). Results: A total of 40 patients were enrolled. The most common severe adverse events included neutropenia, abdominal pain, asthenia, and diarrhoea. Three patients (7.5%) achieved an objective response, with an additional 17 (42.5%) demonstrating stable disease for a minimum of two cycles. Ten (31.3%) of 32 patients with an elevated baseline CA19-9 had a >50% biomarker decline. The study met its primary end point with an OS 3-month of 75%, with median progression-free survival and overall survival of 2.4 and 5.2 months, respectively. Conclusion: PEP02 demonstrates moderate antitumour activity with a manageable side effect profile for metastatic, gemcitabine-refractory pancreatic cancer patients. Given the limited treatment options available to this patient population, a phase 3 trial of PEP02 (MM-398), referred to as NAPOLI-1, is currently underway.
