PharmaEngine Announces Taiwan FDA Approval of ONIVYDE (TM) (irinotecan liposome injection) for the Treatment of Metastatic Pancreatic Cancer
ONIVYDE in combination with fluorouracil and leucovorin is the only regulatory approved treatment for the patients with metastatic adenocarcinoma of the pancreas after disease progression following gemcitabine-based therapy
TAIPEI, Oct. 22, 2015 /PRNewswire/ -- PharmaEngine, Inc. (TWO: 4162) announced that the Taiwan Food and Drug Administration (TFDA) has approved ONIVYDETM (irinotecan liposome injection) 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 for use as a single agent. The TFDA is the first regulatory authority in the world granting the approval of ONIVYDE.
"We are very grateful that the TFDA granted the regulatory approval in such a rapid pace, especially the accelerated efforts made by the Center of Drug Evaluation (CDE) and the TFDA," said C. Grace Yeh, Ph.D., President and CEO of PharmaEngine. "We are highly appreciative to our license partner, Merrimack Pharmaceuticals, Inc. (NASDAQ: MACK), for their valuable collaboration, as well as their timely and full support during the review period. Also, we sincerely thank all the patients, the investigators and their caregivers for their participation and significant contribution to advance the management of pancreatic cancer patients. Lastly, PharmaEngine is proud of this remarkable achievement in our company's history, and we are indebted to many people who encouraged us to persevere for more than a decade in developing ONIVYDE."
ONIVYDE (formerly known as MM-398, PEP02, or nal-IRI) is a proprietary liposome encapsulation of irinotecan, a topoisomerase 1 inhibitor. The new drug application (NDA) to the TFDA was based on the NDA data package submitted by Merrimack to the U.S. FDA and the positive data from a global Phase 3 study (NAPOLI-1) conducted in patients with metastatic pancreatic cancer who previously received gemcitabine-based therapy. A total of 417 patients were recruited at 76 sites in 14 countries; 95 patients (22.8%) were from Taiwan which ranked the top enrollment rate. The study results of NAPOLI-1 showed ONIVYDE in combination with 5-FU/LV achieved the primary and secondary endpoints by demonstrating a clinically and statistically significant improvement in overall survival, progression free survival and overall response rate compared to the control group of patients who received 5-FU/LV. The ONIVYDE monotherapy arm in this study did not achieve the primary endpoint. The most common adverse reactions (>20%) with ONIVYDE were diarrhea, fatigue/asthenia, vomiting, nausea, decreased appetite, stomatitis and pyrexia and the most common severe laboratory abnormalities (>10% Grade 3 or 4) were lymphopenia and neutropenia. This was the first global Phase 3 study in a post-gemcitabine setting to demonstrate a survival benefit in this aggressive disease.
Merrimack submitted an NDA to the U.S. FDA in April 2015 and was granted priority review in June with a Prescription Drug User Fee Act (PDUFA) date of October 24, 2015. The marketing authorization application (MAA) submitted to the European Medicines Agency (EMA) by Baxalta Incorporated in May 2015, was accepted for review in June 2015, and there are plans for submissions to other countries. ONIVYDE has orphan drug designation in the US, EU and elsewhere.
About Pancreatic Cancer
According to the 2013 statistical data from the Department of Health of Taiwan (DOH), pancreatic cancer is the eighth leading cause of cancer deaths in Taiwan and about 1,700 people die of pancreatic cancer every year. Metastatic pancreatic cancer is almost uniformly fatal, with an overall survival rate of approximately 6 percent at 5 years worldwide. The drug used for the first-line therapy of the pancreatic cancer is gemcitabine. Currently, the patients with metastatic pancreatic cancer who progressed following gemcitabine treatment have no set standard of care.
About ONIVYDE (MM-398, PEP02, or nal-IRI)
PharmaEngine licensed the Asian (2003) European (2005) development, manufacturing and commercialization rights of ONIVYDE from Hermes BioSciences, Inc., South San Francisco, CA. Hermes was acquired by Merrimack Pharmaceuticals, Inc., Cambridge, MA in 2009. After completed preclinical, Phase 1 and 2 clinical studies, PharmaEngine licensed its Asian and European rights except Taiwan, back to Merrimack in 2011. During 2011 and 2014, Merrimack sponsored the global phase 3 NAPOLI-1 study in metastatic pancreatic cancer patients. In September 2014, Merrimack licensed ONIVYDE outside of the U.S. and Taiwan to Baxalta Incorporated (NYSE: BXLT), formerly Baxter International's BioScience business.
IMPORTANT SAFETY INFORMATION
INDICATION

Limitation of Use: ONIVYDE is not indicated as a single agent for the treatment of patients with metastatic adenocarcinoma of the pancreas.
WARNING: SEVERE NEUTROPENIA and SEVERE DIARRHEA
Fatal neutropenic sepsis occurred in 0.8% of patients receiving ONIVYDE. Severe or life-threatening neutropenic fever or sepsis occurred in 3% and severe or life-threatening neutropenia occurred in 20% of patients receiving ONIVYDE in combination with fluorouracil (5-FU) and leucovorin (LV). Withhold ONIVYDE for absolute neutrophil count below 1500/mm3 or neutropenic fever. Monitor blood cell counts periodically during treatment.
Severe diarrhea occurred in 13% of patients receiving ONIVYDE in combination with 5-FU/LV. Do not administer ONIVYDE to patients with bowel obstruction. Withhold ONIVYDE for diarrhea of Grade 2-4 severity. Administer loperamide for late diarrhea of any severity. Administer atropine, if not contraindicated, for early diarrhea of any severity.
CONTRAINDICATION
ONIVYDE is contraindicated in patients who have experienced a severe hypersensitivity reaction to ONIVYDE or irinotecan HCl.
WARNING AND PRECAUTIONS
Severe Neutropenia
ONIVYDE can cause severe or life-threatening neutropenia and fatal neutropenic sepsis. In a clinical study, the incidence of fatal neutropenic sepsis was 0.8% among patients receiving ONIVYDE, occurring in one of 117 patients in the ONIVYDE plus fluorouracil/leucovorin (ONIVYDE/5-FU/LV) arm and one of 147 patients receiving ONIVYDE as a single agent. Severe or life-threatening neutropenia occurred in 20% of patients receiving ONIVYDE/5-FU/LV vs 2% of patients receiving 5-FU/LV. Grade 3/4 neutropenic fever/neutropenic sepsis occurred in 3% of patients receiving ONIVYDE/5-FU/LV, and did not occur in patients receiving 5-FU/LV.
In patients receiving ONIVYDE/5-FU/LV, the incidence of Grade 3/4 neutropenia was higher among Asian [18/33 (55%)] vs White patients [13/73 (18%)]. Neutropenic fever/neutropenic sepsis was reported in 6% of Asian vs 1% of White patients.
Severe Diarrhea
ONIVYDE can cause severe and life-threatening diarrhea. Do not administer ONIVYDE to patients with bowel obstruction. Severe and life-threatening late-onset (onset >24 hours after chemotherapy) and early-onset diarrhea (onset <24 hours after chemotherapy, sometimes with other symptoms of cholinergic reaction) were observed. An individual patient may experience both early- and late-onset diarrhea.
In a clinical study, Grade 3/4 diarrhea occurred in 13% of patients receiving ONIVYDE/5-FU/LV vs 4% receiving 5-FU/LV. Grade 3/4 late-onset diarrhea occurred in 9% of patients receiving ONIVYDE/5-FU/LV vs 4% in patients receiving 5-FU/LV; the incidences of early-onset diarrhea were 3% and no Grade 3/4 incidences, respectively. Of patients receiving ONIVYDE/5-FU/LV, 34% received loperamide for late-onset diarrhea and 26% received atropine for early-onset diarrhea.
Interstitial Lung Disease (ILD)
Irinotecan HCl can cause severe and fatal ILD. Withhold ONIVYDE in patients with new or progressive dyspnea, cough, and fever, pending diagnostic evaluation. Discontinue ONIVYDE in patients with a confirmed diagnosis of ILD.
Severe Hypersensitivity Reactions
Irinotecan HCl can cause severe hypersensitivity reactions, including anaphylactic reactions. Permanently discontinue ONIVYDE in patients who experience a severe hypersensitivity reaction.
Embryo-Fetal Toxicity
Based on animal data with irinotecan HCl and the mechanism of action of ONIVYDE, ONIVYDE can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during and for one month after ONIVYDE treatment.
