Jazz Pharmaceuticals to Present Data Showcasing Clinical Advances Across Hematology/Oncology at ASH 2021 Annual Meeting

DUBLIN, Nov. 4, 2021 /PRNewswire/ -- Jazz Pharmaceuticals plc (Nasdaq: JAZZ) today announced that 16 new data abstracts from across its hematology/oncology development program will be presented at the 63^rd American Society of Hematology (ASH) Annual Meeting, which will be held December 11-14, 2021. This includes five presentations from investigator-sponsored trials and three presentations from collaboration studies with The University of Texas MD Anderson Cancer Center (MD Anderson).

"The data at ASH demonstrates Jazz's focus on making a difference for people living with rare forms of leukemias and blood cancers, both through the development of new treatment options as well as further evaluating our currently approved medicines," said Robert Iannone, M.D., M.S.C.E., executive vice president, research and development and chief medical officer of Jazz Pharmaceuticals. "Our support of several investigator-sponsored and collaboration trials exemplifies our commitment to working with experts to enable studies beyond our own company-sponsored trials, and to identifying new treatment options for patients through a variety of means."

Highlights at ASH include:

• A poster presentation sharing, for the first time, data from the Phase 2/3 study of Rylaze in patients with acute lymphoblastic leukemia (ALL)/lymphoblastic lymphoma (LBL) who developed hypersensitivity or silent inactivation to a long-acting E. coli–derived asparaginase.
• Results for Vyxeos^® (daunorubicin and cytarabine) in acute myeloid leukemia (AML) including an oral presentation from a real-world evidence study of Vyxeos use in newly diagnosed patients and a poster presentation from a Phase 1b study of lower-dose Vyxeos in combination with venetoclax in patients with AML who are unfit for intensive chemotherapy.
• Data for Vyxeos use in new patient populations, including oral presentations of two studies of Vyxeos as treatment in higher risk Myelodysplastic Syndrome (MDS).
• A poster presentation with final results from a real-world evidence study, DEFIFrance, of Defitelio^® (defibrotide sodium) treatment in adults with severe or very severe veno-occlusive disease/sinusoidal obstruction syndrome after hematopoietic cell transplantation.

The ASH abstracts are available online starting today, November 4 at https://ash.confex.com/ash/2021/webprogram/start.html.

About Rylaze™ (asparaginase erwinia chrysanthemi (recombinant)-rywn)
Rylaze, also known as JZP458, is approved in the U.S. for use as a component of a multi-agent chemotherapeutic regimen for the treatment of acute lymphoblastic leukemia (ALL) or lymphoblastic lymphoma (LBL) in pediatric and adult patients one month and older who have developed hypersensitivity to E. coli-derived asparaginase. Rylaze has orphan drug designation for the treatment of ALL/LBL in the United States. Rylaze is a recombinant erwinia asparaginase that uses a novel Pseudomonas fluorescens expression platform. JZP458 was granted Fast Track designation by the U.S. Food and Drug Administration (FDA) in October 2019 for the treatment of this patient population. Rylaze was approved as part of the Real-Time Oncology Review program, an initiative of the FDA's Oncology Center of Excellence designed for efficient delivery of safe and effective cancer treatments to patients.

• Serious allergic reactions to RYLAZE
• Serious swelling of the pancreas (stomach pain), serious blood clots, or serious bleeding during previous asparaginase treatment

RYLAZE may cause serious side effects, including:
