Jazz Pharmaceuticals To Present Data From Ongoing Evaluations Of Defibrotide At The 2016 BMT Tandem Meeting

JAZZ | February 18, 2016

Jazz-Sponsored Oral Presentations Include: Results from a Pivotal Phase 3 Trial for the Treatment of VOD with MOD, Sub-Analysis Data from a Phase 3 Pediatric Trial for VOD Prophylaxis, and an Exploratory Post-Hoc Analysis from an Expanded Access Treatment of VOD / SOS Study to Evaluate Timing of Treatment Initiation 10 Jazz-Sponsored Posters Also to Be Presented

DUBLIN, Feb. 18, 2016 /PRNewswire/ -- Jazz Pharmaceuticals plc (Nasdaq: JAZZ) announced today that researchers will present three Jazz-sponsored oral abstracts related to the ongoing evaluation of defibrotide, an investigational medicine being studied in the United States (U.S.) for the treatment of adult and pediatric patients with hepatic veno-occlusive disease (VOD), also known as sinusoidal obstruction syndrome (SOS), with evidence of multi-organ dysfunction (MOD) following hematopoietic stem-cell transplantation (HSCT). Data will be presented at the 2016 BMT (Bone Marrow Transplantation) Tandem Meeting, the combined annual meetings of the American Society of Blood and Marrow Transplantation (ASBMT) and the Center for International Blood and Marrow Transplant Research (CIBMTR), taking place from February 18 to 22 in Honolulu, Hawaii.

The three oral scientific presentations include: 1) Results from the pivotal, historically controlled Phase 3 trial of defibrotide for the treatment of hepatic VOD, also known as SOS, with MOD following HSCT; 2) results from a sub-analysis of data from an open-label, randomized, Phase 3 pediatric trial of defibrotide for the prophylaxis of VOD, including patients with specific VOD / SOS risk factors; and 3) results from an exploratory post-hoc analysis of data from an expanded access treatment of VOD / SOS study to evaluate the timing of defibrotide initiation post-VOD diagnosis and impact on Day +100 survival following HSCT.

"The data presented at this year's BMT Tandem Meeting add to the growing body of scientific evidence regarding the efficacy and safety of defibrotide in the treatment of hepatic VOD with MOD following HSCT," said Karen Smith, M.D., Ph.D., global head of research and development and chief medical officer at Jazz Pharmaceuticals. "As we explore additional potential indications for defibrotide, the more we know, the more we might be able to do to fill unmet needs for patients."

The two Phase 3 pivotal study oral presentations will take place on Thursday, February 18, 2016, from 4:45 to 5:15 pm Hawaii-Aleutian Standard Time (HAST) during Session A: Oral Abstracts – Late Effects, Supportive Care and Quality of Life, in Exhibit Hall 3 at the Hawaii Convention Center:

Presentation 7, Paul G. Richardson, M.D., "Defibrotide for the Treatment of Hepatic Veno-Occlusive Disease/Sinusoidal Obstruction Syndrome with Multi-Organ Dysfunction: Final Results from a Pivotal, Historically Controlled, Phase 3 Trial." Dr. Richardson and co-authors will present data from an analysis of Day +100 survival (primary endpoint) and complete response (key secondary endpoint) data from a pivotal Phase 3 study of defibrotide in the treatment of VOD with MOD following HSCT. Dr. Richardson is the lead investigator and director of clinical research at the LeBow Institute for Myeloma Therapeutics and the Jerome Lipper Multiple Myeloma Center at the Dana-Farber Cancer Institute and the RJ Corman Professor of Medicine at Harvard Medical School.
Presentation 8, Selim Corbacioglu, M.D., "Defibrotide for Prophylaxis of Hepatic Veno-Occlusive Disease in Pediatric Hematopoietic Stem Cell Transplantation: Sub-analysis Data from an Open-Label, Phase 3, Randomized Trial." Dr. Corbacioglu, of the University of Regensburg, Germany, will present results from a sub-analysis of data from an open-label, randomized, Phase 3 pediatric trial of defibrotide for the prophylaxis of VOD, including patients with specific VOD / SOS risk factors.

The third oral presentation will take place on Sunday, February 21 from 4:45 to 5:00 pm HAST during Session L: Oral Abstracts – Late Effects, Supportive Care and Quality of Life, in room #316 ABC at the Hawaii Convention Center:

Presentation 83, Paul G. Richardson, M.D., "Early Initiation of Defibrotide in Patients with Hepatic Veno-Occlusive Disease/Sinusoidal Obstruction Syndrome Following Hematopoietic Stem Cell Transplantation Improves Day +100 Survival." Dr. Richardson will present results from an exploratory post-hoc analysis of data from an expanded access treatment of VOD / SOS study to evaluate the timing of defibrotide initiation post VOD diagnosis and impact on Day +100 survival following HSCT.

The 10 posters will be presented in the poster sessions in Exhibit Hall 3 at the Hawaii Convention Center. The following will be presented on Thursday, February 18 from 6.45 to 7:45 pm HAST:

About VOD

HSCT is a potentially curative procedure to treat patients with malignant and non-cancerous hematologic disorders such as leukemia, lymphoma and aplastic anemia, congenital immunodeficiency and autoimmune disorders.¹ Hepatic VOD, also known as SOS, is a rare, early and life-threatening complication of HSCT.²

About Defibrotide

In the U.S., defibrotide is an investigational drug for the treatment of patients with hepatic VOD with MOD following HSCT. Defibrotide was granted Orphan Drug Designation by the FDA in May 2003 and has Fast Track designation. A new drug application (NDA) is under review by the U.S. Food and Drug Administration (FDA).

Defibrotide is being made available as an investigational new drug (IND) free of charge through an expanded access Treatment Protocol. The ongoing expanded access Treatment Protocol is currently enrolling patients diagnosed with VOD in the U.S. Expanded access programs are part of an effort by the FDA and the pharmaceutical industry to make investigational drugs available for the treatment of serious or life-threatening diseases in people with limited treatment options. For information about the expanded access defibrotide study, contact Erin Tokunaga at erin.tokunaga@jazzpharma.com or Lam Calderon (1.312.706.6240; 0265-002Gentium@iconplc.com); or visit www.clinicaltrials.gov (Identifier: NCT00628498).

In Europe, defibrotide is marketed under the name Defitelio®▼(defibrotide). In October 2013, the European Commission granted marketing authorization to Defitelio under exceptional circumstances for the treatment of severe hepatic VOD in patients undergoing HSCT therapy. Defitelio received an approval in Israel in May 2015 for the same indication as in the EU.
