Ipsen Presents Real-World Pancreatic Cancer Data on ONIVYDE® at the European Society for Medical Oncology (ESMO) 2018 Annual Congress

CAMBRIDGE, Mass.--(BUSINESS WIRE)-- Ipsen Biopharmaceuticals, an affiliate of Ipsen (Euronext: IPN; ADR: IPSEY), today announced results from a retrospective, observational analysis examining the real-world dosing patterns of patients with metastatic pancreatic cancer (mPC) treated with ONIVYDE^® (irinotecan liposome injection), at this year’s European Society for Medical Oncology (ESMO) annual congress taking place in Munich, Germany, Oct. 19-23, 2018.

Using the Flatiron Health electronic health record (EHR)-derived database, a longitudinal and nationally representative database comprising patient-level structured and unstructured data that is curated via technology-enabled abstraction, researchers identified 257 metastatic pancreatic cancer patients (median age: 67y; IQR: 61–74) who received ONIVYDE + fluorouracil (5-FU) and leucovorin (LV) therapy between November 2015 to August 2017 and analyzed their treatment data to assess dose intensity (DI) over the first 6 weeks of treatment, dose modifications during treatment, and overall duration of exposure (DOE) to ONIVYDE.

The real-world analysis (Poster 735P) describes how ONIVYDE was incorporated in the treatment sequencing that contained prior gemcitabine in the treatment of metastatic pancreatic cancer. In this analysis, the mean dose intensity was 177.8 mg/m² (SD: 74.9 mg/m²). The median dose at initiation was 69.4 mg/m² (IQR: 56.7–70.2); the recommended dose for ONIVYDE is 70 mg/m². In addition, median duration of exposure was 8.9 weeks (IQR: 3.9/19 weeks) in first and second line and 6.3 weeks (IQR: 3.4/12.1 weeks) in third or plus lines.

These results are generally consistent with the NAPOLI-1 trial, however, dose modifications in the real-world analysis were lower (27.2% vs 45% in NAPOLI-1). In the NAPOLI-1 phase 3 trial, dose intensity over 6 weeks and duration of exposure for combination therapy with ONIVYDE was 167.5 mg/m² (SD 44.8) and 8.7 weeks (IQR: 5.4 – 22.0), respectively. Despite these real-world patients being older, having worse performance status and more prior lines of treatment than patients in NAPOLI-1, more than half (59.1%) of patients started ONIVYDE + 5-FU/LV treatment with the recommended ONIVYDE dose (70 mg/m²).

NAPOLI-1 is the largest global, phase 3, randomized, open-label, multicenter trial in patients (N=417) with metastatic pancreatic cancer whose disease had progressed following gemcitabine-based therapy. Patients in the NAPOLI-1 trial being treated with ONIVYDE in combination with fluorouracil (5-FU) and leucovorin (LV) had improved overall survival (OS; primary endpoint) vs 5-FU/LV (6.1 mos vs 4.2 mos; HR = 0.67, 95% CI 0.49–0.92; P = 0.012). ONIVYDE monotherapy had no effect on OS.

ONIVYDE can cause severe, life-threatening neutropenia and diarrhea (see complete Boxed Warning in full prescribing information). ONIVYDE can also cause severe and fatal Interstitial Lung Disease (ILD) and hypersensitivity reactions. These serious adverse events may require withholding or discontinuing treatment with ONIVYDE, a dose reduction and/or supportive treatment. The most common adverse reactions in NAPOLI-1 (≥20%) were diarrhea (59%), fatigue/asthenia (56%), vomiting (52%), nausea (51%), decreased appetite (44%), stomatitis (32%), and pyrexia (23%).

“Patients are at the heart of what we do, with unmet need guiding our development strategy and driving how we innovate for patient care,” said Dr. Sotirios Stergiopoulos, Senior Vice President, Head of Global Medical Affairs and Chief Medical Officer. “This real-world data analysis provides further evidence in support of the dose intensity and duration of exposure of ONIVYDE and 5-FU/LV observed in the NAPOLI-1 phase 3 trial. This retrospective analysis allows us to further understand how patients with pancreatic cancer are receiving and managing their treatment in real-world settings.”

Dr. Afsaneh Barzi, Study Investigator, Norris Comprehensive Cancer Center, University of Southern California, Los Angeles, Calif., notes, “As a physician who treats patients with metastatic pancreatic cancer, I find it reassuring and welcome the unique evidence the Flatiron dosing analysis provides in demonstrating the real-world usage of ONIVYDE + 5-FU/LV in a large sample of metastatic pancreatic cancer patients being treated in a clinical oncology setting when compared to a clinical trial setting. Data from our real-world practice for clinical analysis serve to further our knowledge about how to continue to effectively treat our patients.”

About Pancreatic Cancer

Pancreatic cancer is a rare and deadly disease with about 55,440 people (29,200 men and 26,240 women) being diagnosed with pancreatic cancer in the United States alone.¹ More than half are diagnosed with metastatic disease, which has an overall 5-year survival rate of less than three percent (3%)¹, and often rapidly progresses during or shortly after receiving chemotherapy.² Pancreatic cancer accounts for about 3% of all cancers, and is the third leading cause of cancer-related death in the United States, surpassing breast cancer.¹ It is expected to become the second leading cause of cancer-related death in the U.S. by the year 2030, surpassing colorectal cancer.^1,3

About ONIVYDE^®

ONIVYDE is an encapsulated formulation of irinotecan. This long-circulating liposomal form is designed to increase length of tumor exposure to both irinotecan and its active metabolite, SN38. ONIVYDE is approved by the U.S. FDA, EMA and many other countries. In the U.S., ONIVYDE is approved for use in combination with fluorouracil (5-FU) and leucovorin (LV) for the treatment of patients with metastatic adenocarcinoma of the pancreas after disease progression following gemcitabine-based therapy. ONIVYDE is not indicated as a single agent for the treatment of patients with metastatic adenocarcinoma of the pancreas. Ipsen has gained exclusive commercialization rights for the current and potential future indications for ONIVYDE in the U.S., as well as the current licensing agreements with Servier for commercialization rights ex-U.S. and PharmaEngine for Taiwan.

CONTRAINDICATION

ONIVYDE^® is contraindicated in patients who have experienced a severe hypersensitivity reaction to ONIVYDE^® or irinotecan HCl.

WARNINGS AND PRECAUTIONS
