Jazz Pharmaceuticals To Present New Analysis Of Defibrotide Data In Patients With Hepatic Veno-Occlusive Disease (VOD) At American Society of Hematology Annual Meeting
DUBLIN, Dec. 2, 2014 /PRNewswire/ -- Jazz Pharmaceuticals plc (Nasdaq: JAZZ) announced today that researchers will present the results of a number needed to treat (NNT; an epidemiological measure of effectiveness) analysis from a historically controlled Phase 3 clinical trial evaluating the use of defibrotide for the treatment of severe hepatic veno-occlusive disease (severe VOD or sVOD) in patients undergoing hematopoietic stem-cell transplantation (HSCT) therapy. Researchers will also present updates from an international compassionate use program and an expanded access / treatment investigational new drug (IND) study in the United States (U.S.). These two updates will include data evaluating the use of defibrotide in the treatment of VOD, a rare, early complication in patients undergoing HSCT. These data will be presented in posters at the American Society of Hematology (ASH) 56th Annual Meeting and Exposition in San Francisco, California, taking place from December 6 - 9, 2014.
Earlier this year, Jazz Pharmaceuticals acquired the rights to defibrotide in the U.S. and other markets in North America, South America and Central America. Defibrotide has a fast track regulatory path designation in the U.S. The company plans to initiate a rolling new drug application (NDA) submission to the U.S. Food and Drug Administration for defibrotide for the treatment of severe VOD by the end of the year and anticipates completing the submission in the first half of 2015.
In Europe, defibrotide is marketed under the name Defitelio® (defibrotide). Defitelio is the first and only licensed product in Europe for the treatment of severe VOD in patients over one month of age undergoing HSCT therapy.
"The analyses being presented at ASH this year will further enhance our understanding of defibrotide's activity in the treatment of VOD overall, and of severe VOD in particular," said Paul G. Richardson, M.D., clinical program leader 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. "Importantly, the NNT analysis to be presented will provide additional information on the clinical impact of treatment, further supporting the use of defibrotide as a potential therapeutic option for patients in the treatment of severe VOD."
All posters will be presented in the North Building, Hall E of the Moscone Center in San Francisco, and include:
- Saturday, December 6, 2014, 5:30-7:30 PM (PST), Session 721, Poster I: Corbacioglu S, et al., Defibrotide for the Treatment of Hepatic Veno-Occlusive Disease: An Update from the International Compassionate Use Program in 710 Patients. Abstract #1138.
- Sunday, December 7, 2014, 6:00-8:00 PM (PST), Session 721, Poster II: Richardson PG, et al., Defibrotide for the Treatment of Severe Hepatic Veno-Occlusive Disease: An Analysis of Clinical Benefit as Determined by Number Needed to Treat (NNT) to Achieve Complete Response and to Improve Survival. Abstract #2469.
- Sunday, December 7, 2014, 6:00-8:00 PM (PST), Session 721, Poster II: Richardson PG, et al., Updated Results from a Large, Ongoing, Treatment IND Study Using Defibrotide for Patients with Hepatic Veno-Occlusive Disease. Abstract #2470.
In addition, results from an analysis supported by Jazz Pharmaceuticals that modeled the impact of using pediatric-inspired treatment protocols compared with hyper-CVAD protocols on outcomes for adolescents and young adults with Philadelphia negative acute lymphoblastic leukemia (ALL) will be presented in a poster session on Saturday, December 6, 2014, from 5:30-7:30 PM (Abstract #1281).
"We are pleased to be able to contribute to the scientific presentations at this year's ASH meeting and to provide physicians with additional information regarding the treatment of patients with severe VOD and ALL," said Jeffrey Tobias, M.D., executive vice president and chief medical officer of Jazz Pharmaceuticals.

The most frequent adverse events observed during pre-marketing use were hemorrhage, hypotension and coagulopathy.7 Please consult the Defitelio SmPC for the full list of all side effects reported with Defitelio.
This medicinal product is subject to additional monitoring. This will allow quick identification of new safety information. Healthcare professionals are asked to report any suspected adverse reactions via the national reporting system found under section 4.8 of the SmPC.
About VOD
VOD is an early complication in patients undergoing HSCT therapy. In its severe form, VOD can be life-threatening and is associated with multi-organ failure; it is fatal in over 80% of patients.1,2 HSCTs are performed with curative intent in patients with hematological malignancies, selected solid tumors and some non-malignant disorders, such as serious hemoglobinopathies.3,4 In the EU, VOD is designated as a rare disease, affecting less than five in 10,000 people. Studies have reported a wide range of incidence rates for VOD. Generally, data indicate that approximately 14% of patients undergoing HSCT develop VOD.1,5,6
