"Following recent trial results showing the potential of zanidatamab to treat HER2-expressing gastric and biliary tract cancers at ASCO (Free ASCO Whitepaper) GI, ASCO (Free ASCO Whitepaper) and ESMO (Free ESMO Whitepaper) this year, we’re excited to share updated data at SABCS in HER2-amplified and hormone receptor-positive metastatic breast cancer when zanidatamab is used in combination to target the HER2, CDK4/6 and hormone receptor pathways," said Rob Iannone, M.D., M.S.C.E., executive vice president, global head of research and development of Jazz Pharmaceuticals. "SABCS will also feature data from a trial of zanidatamab in neoadjuvant breast cancer. Additionally, we look forward to sharing new data through numerous presentations at ASH (Free ASH Whitepaper) 2023 that underscore our commitment to improving standards of care in blood cancer and other hematologic diseases, as well as real-world findings at NACLC that provide evidence of Zepzelca’s safety in clinical practice for the treatment of second-line small cell lung cancer."

Notable presentations at this year’s SABCS, ASH (Free ASH Whitepaper) and NACLC meetings include:

A SABCS oral presentation (late-breaking abstract) featuring primary results from a Phase 2a study for a chemotherapy-free option in heavily pretreated patients with HER2+/HR+ mBC treated with the combination of zanidatamab plus palbociclib and fulvestrant.
An investigator-sponsored (MD Anderson Cancer Center) SABCS poster presentation featuring results of a Phase 1 trial evaluating neoadjuvant zanidatamab in patients with stage 1 node-negative HER2+ breast cancer as a single-agent chemotherapy-free option.
An ASH (Free ASH Whitepaper) poster presentation of the complete pivotal, Phase 2/3 trial results of Rylaze (asparaginase erwinia chrysanthemi (recombinant)-rywn) in acute lymphoblastic leukemia (ALL) or lymphoblastic lymphoma (LBL), which includes efficacy, safety and population pharmacokinetic modeling from intramuscular (IM) and intravenous (IV) dosing. The combination of observed and modeled results demonstrates Rylaze achieved therapeutic nadir serum asparaginase activity (NSAA) levels in the vast majority of patients via multiple dosing schedules with a safety profile consistent with prior studies and no new safety signals identified. Treatment‐related adverse events (TRAEs) ≥ grade 3 occurred in 126/228 (55%) patients with no TRAEs that led to death.1
Two NACLC poster presentations of real-world data for Zepzelca (lurbinectedin) in the second-line and later settings for the treatment of small cell lung cancer (SCLC).

About Zanidatamab
Zanidatamab is an investigational bispecific antibody that can simultaneously bind two non-overlapping epitopes of HER2, known as biparatopic binding. This unique design results in multiple mechanisms of action including dual HER2 signal blockade, increased binding and removal of HER2 protein from the cell surface, and immune-mediated cytotoxicity leading to encouraging antitumor activity in patients. Zanidatamab is being developed in multiple clinical trials as a targeted treatment option for patients with solid tumors that express HER2. Zanidatamab is being developed by Jazz and BeiGene, Ltd. (BeiGene) under license agreements from Zymeworks, which first developed the molecule.

The U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy designation for zanidatamab in patients with previously treated HER2 gene-amplified biliary tract cancers (BTC), and two Fast Track designations for zanidatamab: one as a single agent for refractory BTC and one in combination with standard of care chemotherapy for first-line gastroesophageal adenocarcinoma (GEA). Additionally, zanidatamab has received Orphan Drug designations from FDA for the treatment of BTC and GEA, as well as Orphan Drug designation from the European Medicines Agency for the treatment of BTC and gastric cancer. Zanidatamab was also granted Breakthrough Therapy designation from the Center for Drug Evaluation (CDE) in China.

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) and lymphoblastic lymphoma (LBL) in adult and pediatric patients one month or 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, or recombinant Erwinia is a short-acting distinct asparaginase derived from a novel Pseudomonas fluorescens expression platform to help ensure robustness of supply to meet patient needs. 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.2

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.4

The FDA approved Zepzelca under accelerated approval in June 2020 for the treatment of adult patients with metastatic SCLC with disease progression on or after platinum-based chemotherapy. The approval is based on overall response rate (ORR) and duration of response demonstrated in an open-label, monotherapy clinical study. In December 2021, Jazz and PharmaMar announced the initiation of LAGOON, a confirmatory Phase 3 clinical trial of Zepzelca for the treatment of patients with relapsed small cell lung cancer. If positive, LAGOON could confirm the benefit of Zepzelca in the treatment of small cell lung cancer (SCLC) when patients progress following 1L treatment with a platinum-based regimen and support full approval in the U.S.

Zepzelca is a prescription medicine used to treat adults with SCLC 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:
