Company to host investor webcast on June 2, 2023, to review zanidatamab BTC data presentation

DUBLIN, April 27, 2023 /PRNewswire/ -- Jazz Pharmaceuticals plc (Nasdaq: JAZZ) today announced that the company, along with its partners, will present nine abstracts at the American Society of Clinical Oncology (ASCO) Annual Meeting from June 2-6, 2023. Presentations include clinical data from trials of zanidatamab, Zepzelca^® (lurbinectedin) and Vyxeos^® (daunorubicin and cytarabine).

"We are thrilled to present, together with our partner Zymeworks, an oral presentation of pivotal trial results in patients with HER2-positive BTC, an aggressive disease that currently has no FDA-approved HER2-directed treatment options," said Rob Iannone, M.D., M.S.C.E., executive vice president, global head of research and development of Jazz Pharmaceuticals. "The breadth of oncology data being presented by Jazz and our partners reflects our relentless focus on raising the standard of care for some of the most difficult-to-treat cancers." 

Pivotal data from the Phase 2b study of the bispecific antibody zanidatamab in previously treated HER2-amplified BTC was selected by ASCO as an oral presentation. In addition, updated results from a Phase 1b/2 study of zanidatamab in combination with docetaxel as a first-line therapy for patients with advanced HER2-positive breast cancer will be presented by the trial sponsor, BeiGene.

Other presentations at the annual meeting feature data from our oncology pipeline and current product portfolio, across a range of solid tumors and hematological malignancies, include:

• An oral presentation from a Jazz-supported Investigator Sponsored Trial (IST) featuring results from a Phase 1b study evaluating the efficacy of lurbinectedin in combination with doxorubicin in soft-tissue sarcoma (STS), which is intended to serve as a lead-in to a randomized Phase 2 trial in leiomyosarcoma (LMS)
• A poster presentation of a post-hoc analysis using Phase 3 trial data to investigate the impact of Vyxeos versus 7+3 on cardiac impairment in older adults with newly diagnosed high-risk or secondary acute myeloid leukemia (AML)

The full ASCO abstracts will be available on May 25, 2023, after 5 p.m. ET. The abstract titles are available at: https://meetings.asco.org/meetings/2023-asco-annual-meeting/299/program-guide/scheduled-sessions

About Zanidatamab
Zanidatamab is an investigational bispecific antibody, based on Zymeworks' Azymetric™ platform, 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 potent effector function leading to encouraging antitumor activity in patients. Zymeworks, along with collaborators Jazz and BeiGene, Ltd. (BeiGene), are developing zanidatamab in multiple clinical trials as a targeted treatment option for patients with solid tumors that express HER2.

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 gastric cancer. Zanidatamab was also granted Breakthrough Therapy designation from the Center for Drug Evaluation (CDE) in China.

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.¹

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:

• 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.

Females who 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:

• fever or any other signs of infection
• unusual bruising or bleeding
• tiredness
• pale colored skin
• Liver problems. Increased liver function tests are common with ZEPZELCA, and can also be severe. Your healthcare provider should do blood tests to check your liver function before you start and during treatment with ZEPZELCA.

Tell your healthcare provider right away if you develop symptoms of liver problems including:

• 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)
• increased liver function blood tests
• increased blood sugar (glucose)
• nausea
• decreased appetite
• muscle and joint (musculoskeletal) pain
• low level of albumin in the blood
• constipation
• trouble breathing
• low levels of sodium and magnesium in the blood
