Key data includes ASCO oral presentation of data from the Rylaze^® (asparaginase erwinia chrysanthemi (recombinant)-rywn) Phase 2/3 trial in Acute Lymphoblastic Leukemia or Lymphoblastic Lymphoma

DUBLIN, May 12, 2022 /PRNewswire/ -- Jazz Pharmaceuticals plc (Nasdaq: JAZZ) today announced that the Company and its partners will present seven abstracts at the American Society of Clinical Oncology (ASCO) Annual Meeting from June 3 – June 7, 2022, and eight abstracts at the 27^th Annual Congress of the European Hematology Association (EHA) from June 9 –12, 2022. Research findings to be presented include data on Rylaze/JZP458, Zepzelca^® (lurbinectedin), Defitelio^® (defibrotide sodium) and Vyxeos^®/Vyxeos^® Liposomal (daunorubicin and cytarabine), also known as JZP351.

"As part of Jazz's commitment to explore potential new applications of our oncology medicines to address critical needs, we continue to advance programs that could impact difficult-to-treat therapeutic areas," said Rob Iannone, M.D., M.S.C.E., executive vice president, global head of research and development of Jazz Pharmaceuticals. "Our growing, early-stage pipeline, combined with ongoing Jazz-sponsored and partner research across our portfolio, is making significant progress when it comes to addressing unmet patient needs in cancers that have historically lacked scientific advancements."

Highlights from Jazz and its investigational sponsors at the congresses feature data for our medicines across a range of solid tumors and hematological malignancies, including:

• An oral presentation at ASCO featuring results from Cohort 1 of a Phase 2/3 trial conducted with the Children's Oncology Group, evaluating the efficacy and safety of Rylaze administered intramuscularly (IM) on a Monday/Wednesday/Friday dosing schedule, for patients living with acute lymphoblastic leukemia (ALL) or lymphoblastic lymphoma (LBL).
• Two poster presentations for JZP351 including preliminary results from Arm B (JZP351 in combination with midostaurin) from the Phase 1b V-FAST trial in adults with previously untreated FLT3-mutated acute myeloid leukemia (AML) and data from the Phase 1b trial evaluating lower-intensity JZP351 + venetoclax in adults with newly diagnosed AML who are unfit for intensive chemotherapy. These data will be presented at both ASCO and EHA.
• Four poster presentations at ASCO evaluating Zepzelca in a range of small cell lung cancer (SCLC) settings, both as a monotherapy and in combination with other therapies, and in BRCA1/2-associated metastatic breast cancer.

About Zepzelca^® (lurbinectedin) 
Zepzelca is an alkylating drug that binds guanine residues within DNA. This triggers a cascade of events that can affect the activity of DNA binding proteins, including some transcription factors, and DNA repair pathways, resulting in disruption of the cell cycle and eventual cell death.²

Zepzelca for injection 4 mg is a prescription medicine used to treat adults with a kind of lung cancer called small cell lung cancer that has spread to other parts of the body (metastatic) and who have received treatment with chemotherapy that contains platinum, and it did not work or is no longer working. Zepzelca is approved based on response rate and how long the response lasted. Additional studies will further evaluate the benefit of Zepzelca for this use. 

Important Safety Information for ZEPZELCA

Before receiving ZEPZELCA, tell your healthcare provider about all of your medical conditions, including if you: 

• have liver or kidney problems. 
• are pregnant or plan to become pregnant. ZEPZELCA can harm your unborn baby. 
  Females who are able to become pregnant: 
• Your healthcare provider should do a pregnancy test before you start treatment with ZEPZELCA. 
• You should use effective birth control (contraception) during treatment with and for 6 months after your final dose of ZEPZELCA. 
• Tell your healthcare provider right away if you become pregnant or think that you are pregnant during treatment with ZEPZELCA. 

Males with female partners who are able to become pregnant should use effective birth control during treatment with and for 4 months after your final dose of ZEPZELCA. 

• Are breastfeeding or plan to breastfeed. It is not known if ZEPZELCA passes into your breastmilk. Do not breastfeed during treatment with ZEPZELCA and for 2 weeks after your final dose of ZEPZELCA. Talk to your healthcare provider about the best way to feed your baby during treatment with ZEPZELCA.

Some people with low white blood cell counts may get fever, or an infection throughout the body (sepsis), that can cause death. Your healthcare provider should do blood tests before you receive each treatment with ZEPZELCA to check your blood cell counts. 

Tell your healthcare provider right away if you develop:

• loss of appetite  
• nausea or vomiting  
• pain on the right side of your stomach area (abdomen) 

Your healthcare provider may temporarily stop treatment, lower your dose, or permanently stop ZEPZELCA if you develop low blood cell counts or liver problems during treatment with ZEPZELCA. 

The most common side effects of ZEPZELCA include: 

• tiredness 
• low white and red blood cell counts 
• increased kidney function blood test (creatinine)
