Jazz Pharmaceuticals to Present Data at 2022 ASH Meeting Showcasing Commitment to Advancing Oncology Research


Key data includes results for intravenous administration of Rylaze® (asparaginase erwinia chrysanthemi (recombinant)-rywn) in Acute Lymphoblastic Leukemia or Lymphoblastic Lymphoma Patients

DUBLIN, Nov. 3, 2022 /PRNewswire/ — Jazz Pharmaceuticals plc (Nasdaq: JAZZ) today announced that 13 abstracts will be presented at the American Society of Hematology (ASH) Annual Meeting from December 10-13, 2022. Research findings to be presented include data from company-sponsored, investigator-sponsored and collaborative trials for Rylaze® (asparaginase erwinia chrysanthemi (recombinant)-rywn)/asparaginase, Vyxeos® (daunorubicin and cytarabine), also known as JZP351, and Defitelio® (defibrotide sodium).

“We’re excited about our continued progress in oncology, including the impact that Rylaze is having to provide patients with a much-needed, reliable therapeutic option for the treatment of acute lymphoblastic leukemia or lymphoblastic lymphoma,” said Rob Iannone, M.D., M.S.C.E., executive vice president, global head of research and development of Jazz Pharmaceuticals. “The data at ASH from across Rylaze, Vyxeos and Defitelio demonstrate our commitment to continued evaluation of our products to make a difference for patients living with rare forms of leukemia and following hematopoietic stem cell transplant.”

Highlights from Jazz and its investigational sponsors at the congress include:

  • A poster featuring results from Part B of a Phase 2/3 trial conducted with the Children’s Oncology Group, evaluating the efficacy, safety, and population pharmacokinetic modeling of Rylaze administered intravenously (IV) in patients living with acute lymphoblastic leukemia (ALL) or lymphoblastic lymphoma (LBL). Results demonstrate that IV administration of Rylaze at 25 mg/m2 every 48 hours is feasible and efficacious with a safety profile consistent with other asparaginases.1
  • A poster sharing a subgroup analysis from Arm B of the V-FAST Master Trial, evaluating outcomes of Vyxeos and midostaurin treatment in adults with newly diagnosed acute myeloid leukemia (de novo and secondary) with FLT3 mutation. Preliminary results suggest the combination of Vyxeos + MID is feasible with a manageable safety profile and promising remission rates in adults with newly diagnosed, FLT3-mutated AML.2
  • A poster from a pooled analysis of two registry studies (DEFIFrance and EBMT PASS) that collected real-world use of Defitelio, which describes the resolution of Veno-occlusive Disease/Sinusoidal Obstruction Syndrome (VOD/SOS) post hematopoietic cell transplantation (HCT). A substantial proportion of patients required >21 days of therapy to achieve resolution. Day 100 survival was higher in patients with VOD/SOS resolution versus without, regardless of severity, highlighting the importance of obtaining resolution of VOD/SOS symptoms to improve patient outcomes.3

The ASH abstracts are available online starting today, November 3, at:

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.4

The full U.S. Prescribing Information for RYLAZE is available at: https://pp.jazzpharma.com/pi/rylaze.en.USPI.pdf

In the U.S., Defitelio® (defibrotide sodium) injection 80mg/mL received U.S. Food and Drug Administration (FDA) marketing approval on March 30, 2016, and it is indicated for the treatment of adult and pediatric patients with hepatic veno-occlusive disease (VOD), also known as sinusoidal obstruction syndrome (SOS), with renal or pulmonary dysfunction following hematopoietic stem-cell transplantation (HSCT) and is the first and only FDA-approved therapy for patients with this rare, potentially fatal complication. Defitelio is not approved for the prevention of VOD.6

Please see full Prescribing Information for Defitelio in the United States. 

In Europe, defibrotide is marketed under the name Defitelio® ▼ (defibrotide).
