Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.1 The Phase 3 HERIZON-BTC-302 confirmatory trial is ongoing to evaluate zanidatamab in combination with standard-of-care therapy versus standard-of-care therapy alone in the first-line setting for patients with HER2-positive BTC. \n\n  \n\n\"BTC is a devastating disease with a poor prognosis and five-year survival rates under five percent in the metastatic setting. Patients with unresectable or metastatic HER2-positive BTC have had a high unmet need with limited treatment options and few approved therapies,\" said Rob Iannone, M.D., M.S.C.E., executive vice president, global head of research and development, and chief medical officer of Jazz Pharmaceuticals. \"The approval of Ziihera, which previously received Breakthrough Therapy Designation from the FDA for this indication, is an important advance and offers the first and only dual HER2-targeted bispecific antibody and chemotherapy-free treatment for patients living with BTC. We look forward to advancing research of zanidatamab in BTC and other HER2-expressing solid tumors, with the goal of improving outcomes for more people diagnosed with these difficult-to-treat HER2-positive cancers.\"\nThe FDA approval of Ziihera is based on compelling data from the HERIZON-BTC-01 trial, which included the evaluation of zanidatamab as a single agent in previously treated HER2-positive (as determined by Roche Diagnostic's PATHWAY® anti-HER-2/neu (4B5) Rabbit Monoclonal Primary Antibody companion diagnostic) BTC and is the largest Phase 2b clinical trial to date specifically for this patient population. The trial achieved its primary endpoint of confirmed objective response rate (cORR) by independent central review (ICR) and results were presented at the American Society of Clinical Oncology (ASCO) Annual Meeting 2023, published in The Lancet Oncology, and included in the 2023 Best of ASCO® program. Longer follow-up data showing improvement upon previously reported DOR were reported at the ASCO Annual Meeting 2024.1\n\"As a clinical investigator and medical oncologist focused on advancing the care of patients with biliary tract and liver cancers, I have experienced firsthand the significant unmet need for effective therapies for patients with these diseases,\" said Dr. James Harding, associate attending, Gastrointestinal Oncology and Early Drug Development Services, at Memorial Sloan Kettering Cancer Center. \"Zanidatamab has demonstrated antitumor activity and is now a new option for patients with HER2-positive biliary tract cancer. I look forward to continued and successful drug development for patients with biliary tract cancer.\"\n\"Metastatic biliary tract cancer, BTC, places a significant burden on patients, affecting their quality of life and their emotional and mental well-being, as well as that of their families,\" said Stacie Lindsey, CEO and founder of the Cholangiocarcinoma Foundation. \"The approval of Ziihera offers a promising treatment option. It provides patients and their loved ones the possibility of more time together and an improved quality of life, which is invaluable for the entire BTC community.\" \nThe efficacy of Ziihera was evaluated in 62 patients with HER2-positive (IHC 3+ by central assessment) BTC in Cohort 1 of HERIZON-BTC-01, with major efficacy outcome measures of ORR and DOR as determined by ICR according to RECIST (Response Evaluation Criteria in Solid Tumors) v1.1.1 The study demonstrated an ORR of 52% [95% confidence interval (CI): 39, 65)] with a Kaplan Meier (KM) estimated median DOR of 14.9 months [95% CI: 7.4-not estimable] by ICR.1\nBoxed Warning for Embryo-fetal toxicity: Exposure to Ziihera during pregnancy can cause embryo-fetal harm. Advise patients of the risk and need for effective contraception.1\nThe safety profile for Ziihera has been demonstrated in 80 patients in the HERIZON-BTC-01 trial. Serious adverse reactions occurred in 53% of patients who received Ziihera. The most common adverse reactions in patients who received Ziihera (≥ 20%) were diarrhea, infusion-related reaction, abdominal pain, and fatigue. Serious adverse reactions in > 2% of patients included biliary obstruction (15%), biliary tract infection (8%), sepsis (8%), pneumonia (5%), diarrhea (3.8%), gastric obstruction (3.8%), and fatigue (2.5%). A fatal adverse reaction of hepatic failure occurred in one patient who received Ziihera. Permanent discontinuation due to an adverse reaction occurred in 2.5% of patients who received Ziihera.1 See additional safety information below and full prescribing information https://pp.jazzpharma.com/pi/ziihera.en.USPI.pdf.\nThe confirmatory, global, randomized Phase 3 trial HERIZON-BTC-302 (NCT06282575) is ongoing and is evaluating zanidatamab in combination with standard-of-care therapy versus standard-of-care therapy alone in the first-line setting for patients with HER2-positive BTC. Continued approval for Ziihera may be contingent upon verification and description of clinical benefit in this confirmatory trial.\nZanidatamab is also being investigated in a number of additional tumor types, including Phase 3 trials in gastroesophageal adenocarcinomas (GEAs) and metastatic breast cancer (mBC). The HERIZON-GEA-01 trial evaluating the potential of zanidatamab plus chemotherapy with or without tislelizumab as first-line treatment for patients with advanced/metastatic HER2-positive GEAs. The EmpowHER-303 trial is evaluating the potential of zanidatamab in combination with physician's choice chemotherapy for the treatment of HER2-positive mBC for patients who have progressed on, or are intolerant to, previous trastuzumab deruxtecan treatment.\nAbout the Phase 2b HERIZON-BTC-01 TrialThe Phase 2b HERIZON-BTC-01 trial of zanidatamab was an open-label, global Phase 2b study, which enrolled 87 patients with HER2-amplified, locally advanced unresectable or metastatic BTC (gallbladder cancer, intra-/extra-hepatic cholangiocarcinoma) into 2 cohorts and included 62 patients with HER2 IHC 3+ BTC. The trial evaluated zanidatamab (20 mg/kg IV every 2 weeks) in patients who had received prior gemcitabine-containing therapy. Patients with prior HER2-targeted therapy use were excluded from the trial. All patients were required to have HER2 status confirmed with tissue samples by a central lab. Patients (n=87) were assigned into two cohorts based on tumor IHC status: Cohort 1 (n=80) included patients who were IHC 2+/3+ (HER2-amplified) and Cohort 2 (n=7) included patients who were IHC 0/1+. Tumors were assessed every 8 weeks per RECIST v1.1. The primary endpoint was ORR by independent central review (ICR) in Cohort 1, with secondary endpoints including other efficacy and safety outcomes.\nInvestor Webcast on Wednesday, December 11, 2024The company will host a webcast on Wednesday, December 11, 2024, at 4:30 p.m. ET / 9:30 p.m. GMT to provide investors an overview of clinical data, patient need and commercialization strategy for Ziihera.

An archive of the webcast will be available for at least one week following the presentation on the Investors section of the company's website at www.jazzpharmaceuticals.com.\nMore information about Ziihera, the Full Prescribing Information, including Boxed Warning and Patient Information, is available here.\nAbout Ziihera® (zanidatamab-hrii)Ziihera (zanidatamab-hrii) is a bispecific HER2-directed antibody that binds to two extracellular sites on HER2. Binding of zanidatamab-hrii with HER2 results in internalization leading to a reduction of the receptor on the tumor cell surface. Zanidatamab-hrii induces complement-dependent cytotoxicity (CDC), antibody-dependent cellular cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP). These mechanisms result in tumor growth inhibition and cell death in vitro and in vivo.1 In the United States, Ziihera is indicated for the treatment of adults with previously treated, unresectable or metastatic HER2-positive (IHC 3+) biliary tract cancer (BTC), as detected by an FDA-approved test.1 The U.S. Food and Drug Administration (FDA) granted accelerated approval for this indication based on overall response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).1 \nZanidatamab is not approved anywhere else in the world.\nZanidatamab 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. \nThe FDA granted Breakthrough Therapy designation for zanidatamab development in patients with previously treated HER2 gene-amplified 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 1L 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. \n\n\n\n\nImportant Safety Information \n\n\n\n\n\nWARNING: EMBRYO-FETAL TOXICITYExposure to ZIIHERA during pregnancy can cause embryo-fetal harm. Advise patientsof the risk and need for effective contraception. \n\n\n\n\n\n\n\nWARNINGS AND PRECAUTIONS\nEmbryo-Fetal ToxicityZIIHERA can cause fetal harm when administered to a pregnant woman. In literature reports, use of a HER2-directed antibody during pregnancy resulted in cases of oligohydramnios and oligohydramnios sequence manifesting as pulmonary hypoplasia, skeletal abnormalities, and neonatal death.\nVerify the pregnancy status of females of reproductive potential prior to the initiation of ZIIHERA. Advise pregnant women and females of reproductive potential that exposure to ZIIHERA during pregnancy or within 4 months prior to conception can result in fetal harm. Advise females of reproductive potential to use effective contraception during treatment with ZIIHERA and for 4 months following the last dose of ZIIHERA.\nLeft Ventricular Dysfunction\nZIIHERA can cause decreases in left ventricular ejection fraction (LVEF). LVEF declined by >10% and decreased to <50% in 4.3% of 233 patients. Left ventricular dysfunction (LVD) leading to permanent discontinuation of ZIIHERA was reported in 0.9% of patients. The median time to first occurrence of LVD was 5.6 months (range: 1.6 to 18.7). LVD resolved in 70% of patients.\nAssess LVEF prior to initiation of ZIIHERA and at regular intervals during treatment. Withhold dose or permanently discontinue ZIIHERA based on severity of adverse reactions.\nThe safety of ZIIHERA has not been established in patients with a baseline ejection fraction that is below 50%.\nInfusion-Related ReactionsZIIHERA can cause infusion-related reactions (IRRs). An IRR was reported in 31% of 233 patients treated with ZIIHERA as a single agent in clinical studies, including Grade 3 (0.4%), and Grade 2 (25%). IRRs leading to permanent discontinuation of ZIIHERA were reported in 0.4% of patients. IRRs occurred on the first day of dosing in 28% of patients; 97% of IRRs resolved within one day.\nPrior to each dose of ZIIHERA, administer premedications to prevent potential IRRs. Monitor patients for signs and symptoms of IRR during ZIIHERA administration and as clinically indicated after completion of infusion. Have medications and emergency equipment to treat IRRs available for immediate use.\nIf an IRR occurs, slow, or stop the infusion, and administer appropriate medical management. Monitor patients until complete resolution of signs and symptoms before resuming. Permanently discontinue ZIIHERA in patients with recurrent severe or life-threatening IRRs.\nDiarrhea\nZIIHERA can cause severe diarrhea.\nDiarrhea was reported in 48% of 233 patients treated in clinical studies, including Grade 3 (6%) and Grade 2 (17%). If diarrhea occurs, administer antidiarrheal treatment as clinically indicated. Perform diagnostic tests as clinically indicated to exclude other causes of diarrhea. Withhold or permanently discontinue ZIIHERA based on severity.\nADVERSE REACTIONS\nSerious adverse reactions occurred in 53% of 80 patients with unresectable or metastatic HER2-positive BTC who received ZIIHERA. Serious adverse reactions in >2% of patients included biliary obstruction (15%), biliary tract infection (8%), sepsis (8%), pneumonia (5%), diarrhea (3.8%), gastric obstruction (3.8%), and fatigue (2.5%). A fatal adverse reaction of hepatic failure occurred in one patient who received ZIIHERA.\nThe most common adverse reactions in 80 patients with unresectable or metastatic HER2-positive BTC who received ZIIHERA (≥20%) were diarrhea (50%), infusion-related reaction (35%), abdominal pain (29%), and fatigue (24%).\nUSE IN SPECIFIC POPULATIONS\nPediatric Use\nSafety and efficacy of ZIIHERA have not been established in pediatric patients.\nGeriatric Use \nOf the 80 patients who received ZIIHERA for unresectable or metastatic HER2-positive BTC, there were 39 (49%) patients 65 years of age and older. Thirty-seven (46%) were aged 65-74 years old and 2 (3%) were aged 75 years or older.\nNo overall differences in safety or efficacy were observed between these patients and younger adult patients.\nAbout Biliary Tract CancerBTC, including gallbladder cancer and intrahepatic and extrahepatic cholangiocarcinoma, account for <1% of all adult cancers globally and are often associated with a poor prognosis.2,3 The human epidermal growth factor receptor 2 (HER2) is a well-validated target for antitumor therapy in other cancers. Across the U.S., Europe, and Japan, approximately 12,000 people are diagnosed with HER2+ BTC annually.4,5,6,7\nAbout Jazz PharmaceuticalsJazz Pharmaceuticals plc (Nasdaq: JAZZ) is a global biopharma company whose purpose is to innovate to transform the lives of patients and their families.
