SHANGHAI & JERSEY CITY, N.J.–(BUSINESS WIRE<\/a>)– \n“Expanding access to treatments for diseases that disproportionately impact women, including breast cancer, the most common cancer among women in the US excluding skin cancer, is at the core of our mission,\u201d said Jon Martin, US Commercial Lead, Biosimilars and Established Brands at Organon.3<\/sup> \u201cNot only is POHERDY the first approved biosimilar to PERJETA in the US, but its approval also builds on Organon\u2019s recent momentum of expanding our biosimilars portfolio in women’s health and oncology. Our collaboration with Henlius is critical to our goal of making health care more sustainable for US patients.\u201d<\/p>\n \n\u201cThe FDA approval of POHERDY marks a significant milestone in Henlius\u2019 global expansion and quality biologics development. As the first pertuzumab biosimilar approved in the US, this important achievement demonstrates our core capability to build a sustainable global R&D system grounded in rigorous scientific and regulatory standards. It also reflects Henlius\u2019 steadfast commitment to its patient-centric philosophy and long-term global strategy,\u201d said Dr. Jason Zhu, Executive Director and Chief Executive Officer of Henlius. \u201cWe will continue accelerating the delivery of quality biologics to benefit more patients worldwide and create greater value for human health.\u201d2<\/sup><\/p>\n \n\u201cThe approval of POHERDY further underscores Henlius\u2019 track record in international registration, together with our strength in quality management and commercialization collaboration,\u201d said Ping Cao, Chief Business Development Officer and Senior Vice President of Henlius. \u201cWe look forward to working closely with our partner Organon to leverage our complementary strengths in supply chain, market, and distribution networks, jointly enhancing access to quality biologics and providing patients with treatment options that combine quality and affordability.\u201d2<\/sup><\/p>\n \nPOHERDY is a HER2\/neu receptor antagonist indicated for use in combination with trastuzumab and docetaxel for the treatment of adults with HER2-positive metastatic breast cancer who have not received prior anti-HER2 therapy or chemotherapy for metastatic disease. POHERDY is also indicated for use in combination with trastuzumab and chemotherapy as (i) neoadjuvant treatment of adults with HER2-positive, locally advanced, inflammatory, or early stage breast cancer (either greater than 2 cm in diameter or node positive) as part of a complete treatment regimen for early breast cancer and (ii) adjuvant treatment of adults with HER2-positive early breast cancer at high risk of recurrence. See full indications below.<\/b><\/p>\n \nPertuzumab products can cause subclinical and clinical cardiac failure manifesting as decreased left ventricular ejection fraction (LVEF) and congestive heart failure (CHF). Evaluate cardiac function prior to and during treatment. Discontinue POHERDY treatment for a confirmed clinically significant decrease in left ventricular function. Exposure to pertuzumab products can cause embryo-fetal death and birth defects. Advise patients of these risks and the need for effective contraception. See additional safety information below.<\/b><\/p>\n \nPOHERDY was approved based on the review of a comprehensive data package, which includes analytical similarity, clinical pharmacokinetic studies, and comparative clinical studies demonstrating that POHERDY is highly similar to and interchangeable with the reference product PERJETA in terms of safety, purity, and potency (safety and effectiveness).4,5<\/sup><\/p>\n \nIn 2022, Henlius entered into a license and supply agreement with Organon, granting Organon the exclusive commercialization rights to multiple biosimilars, including POHERDY. The agreement covers exclusive global commercialization rights except for China.6<\/sup> The FDA approval of POHERDY will further enhance the partners\u2019 oncology portfolio and their ability to deliver quality biologics to more patients.2<\/sup><\/p>\n About POHERDY\u00ae <\/sup>(pertuzumab-dpzb)<\/span><\/b><\/p>\n POHERDY is a HER2\/neu receptor antagonist indicated for:<\/b><\/p>\n SELECTED SAFETY INFORMATION<\/b><\/p>\n LEFT VENTRICULAR DYSFUNCTION and EMBRYO-FETAL TOXICITY<\/b><\/p>\n CONTRAINDICATIONS<\/b><\/p>\n \nPOHERDY is contraindicated in patients with known hypersensitivity to pertuzumab products or to any of its excipients.<\/p>\n WARNINGS AND PRECAUTIONS<\/b><\/p>\n Left Ventricular Dysfunction<\/b><\/p>\n \nPertuzumab products can cause left ventricular dysfunction, including symptomatic heart failure. Decreases in LVEF have been reported with drugs that block HER2 activity, including pertuzumab products.<\/p>\n \nAssess LVEF prior to initiation of POHERDY and at regular intervals during treatment to ensure that LVEF is within normal limits. If the LVEF declines and has not improved, or has declined further at the subsequent assessment, consider permanent discontinuation of POHERDY and trastuzumab.<\/p>\n \nIn the pertuzumab-treated patients with MBC in CLEOPATRA, left ventricular dysfunction occurred in 4% of patients, and symptomatic left ventricular systolic dysfunction (LVSD) (congestive heart failure) occurred in 1% of patients. Patients who received prior anthracyclines or prior radiotherapy to the chest area may be at higher risk of decreased LVEF or left ventricular dysfunction.<\/p>\n \nIn patients receiving pertuzumab as a neoadjuvant treatment in combination with trastuzumab and docetaxel in NeoSphere, LVEF decline >10% and a drop to <50% occurred in 8% of patients, and left ventricular dysfunction occurred in 3% of patients. LVEF recovered to \u226550% in all of these patients.<\/p>\n \nIn patients receiving neoadjuvant pertuzumab in TRYPHAENA, LVEF decline >10% and a drop to <50% occurred in 7% of patients treated with pertuzumab plus trastuzumab and fluorouracil, epirubicin, and cyclophosphamide (FEC) followed by pertuzumab plus trastuzumab and docetaxel, 16% of patients treated with pertuzumab plus trastuzumab and docetaxel following FEC, and 11% of patients treated with pertuzumab in combination with docetaxel, carboplatin, and trastuzumab (TCH). Left ventricular dysfunction occurred in 6% of patients treated with pertuzumab plus trastuzumab and FEC followed by pertuzumab plus trastuzumab and docetaxel, 4% of patients treated with pertuzumab plus trastuzumab and docetaxel following FEC, and 3% of patients treated with pertuzumab in combination with TCH. Symptomatic LVSD occurred in 4% of patients treated with pertuzumab plus trastuzumab and docetaxel following FEC, 1% of patients treated with pertuzumab in combination with TCH, and none of the patients treated with pertuzumab plus trastuzumab and FEC followed by pertuzumab plus trastuzumab and docetaxel. LVEF recovered to \u226550% in all but 1 patient.<\/p>\n \nIn patients receiving neoadjuvant pertuzumab in BERENICE, in the neoadjuvant period, LVEF decline \u226510% and a drop to <50% as measured by ECHO\/MUGA assessment occurred in 7% of patients treated with pertuzumab plus trastuzumab and paclitaxel following dose-dense doxorubicin and cyclophosphamide (ddAC) and 2% of patients treated with pertuzumab plus trastuzumab and docetaxel following FEC. Ejection fraction decreased (asymptomatic LVD) occurred in 7% of patients treated with pertuzumab plus trastuzumab and paclitaxel following ddAC and 4% of the patients treated with pertuzumab plus trastuzumab and docetaxel following FEC in the neoadjuvant period. Symptomatic LVSD (New York Heart Association [NYHA] Class III\/IV Congestive Heart Failure) occurred in 2% of patients treated with pertuzumab plus trastuzumab and paclitaxel following ddAC and none of the patients treated with pertuzumab plus trastuzumab and docetaxel following FEC in the neoadjuvant period.<\/p>\n \nIn patients receiving adjuvant pertuzumab in APHINITY, the incidence of symptomatic heart failure (NYHA Class III\/IV) with a LVEF decline \u226510% and a drop to <50% was 0.6%. Of the patients who experienced symptomatic heart failure, 47% of pertuzumab-treated patients had recovered (defined as 2 consecutive LVEF measurements above 50%) at the data cutoff. The majority of the events (86%) were reported in anthracycline-treated patients. Asymptomatic or mildly symptomatic (NYHA Class II) declines in LVEF \u226510% and a drop to <50% were reported in 3% of pertuzumab-treated patients, of whom 80% recovered at the data cutoff.<\/p>\n \nPertuzumab products have not been studied in patients with a pretreatment LVEF value of <50%; a prior history of CHF; decreases in LVEF to <50% during prior trastuzumab therapy; or conditions that could impair left ventricular function such as uncontrolled hypertension, recent myocardial infarction, serious cardiac arrhythmia requiring treatment, or a cumulative prior anthracycline exposure to >360 mg\/m2<\/sup> of doxorubicin or its equivalent.<\/p>\n Embryo-Fetal Toxicity<\/b><\/p>\n \nBased on its mechanism of action and findings in animal studies, pertuzumab products can cause fetal harm when administered to a pregnant woman. Pertuzumab products are HER2\/neu receptor antagonists. Cases of oligohydramnios and oligohydramnios sequence manifesting as pulmonary hypoplasia, skeletal abnormalities, and neonatal death have been reported with use of another HER2\/neu receptor antagonist (trastuzumab) during pregnancy.<\/p>\n \nVerify the pregnancy status of females of reproductive potential prior to the initiation of POHERDY. Advise pregnant women and females of reproductive potential that exposure to POHERDY in combination with trastuzumab during pregnancy or within 7 months prior to conception can result in fetal harm, including embryo-fetal death or birth defects. Advise females of reproductive potential to use effective contraception during treatment and for 7 months following the last dose of POHERDY in combination with trastuzumab.<\/p>\n Infusion-Related Reactions<\/b><\/p>\n \nPertuzumab products can cause serious infusion reactions, including fatal events.<\/p>\n \nIn CLEOPATRA, on the first day, when only pertuzumab was administered, infusion-related reactions occurred in 13% of patients, and <1% were Grade 3 or 4. The most common infusion reactions (\u22651%) were pyrexia, chills, fatigue, headache, asthenia, hypersensitivity, and vomiting. During the second cycle when all drugs were administered on the same day, the most common infusion reactions in the pertuzumab-treated group (\u22651%) were fatigue, dysgeusia, hypersensitivity, myalgia, and vomiting.<\/p>\n \nIn APHINITY, when pertuzumab was administered in combination with trastuzumab and chemotherapy on the same day, infusion-related reactions occurred in 21% of patients, with <1% of patients experiencing Grade 3-4 events.<\/p>\n \nObserve patients closely for 60 minutes after the first infusion and for 30 minutes after subsequent infusions of POHERDY. If a significant infusion-related reaction occurs, slow or interrupt the infusion, and administer appropriate medical therapies. Monitor patients carefully until complete resolution of signs and symptoms. Consider permanent discontinuation in patients with severe infusion reactions.<\/p>\n Hypersensitivity Reactions\/Anaphylaxis<\/b><\/p>\n \nPertuzumab products can cause hypersensitivity reactions, including anaphylaxis.<\/p>\n \nIn CLEOPATRA, the overall frequency of hypersensitivity\/anaphylaxis reactions was 11% in pertuzumab-treated patients, with Grade 3-4 hypersensitivity reactions and anaphylaxis occurring in 2% of patients.<\/p>\n \nIn NeoSphere, TRYPHAENA, BERENICE, and APHINITY, hypersensitivity\/anaphylaxis events were consistent with those observed in CLEOPATRA. In APHINITY, the overall frequency of hypersensitivity\/anaphylaxis was 5% in the pertuzumab-treated group. The incidence was highest in the pertuzumab plus TCH\u2013treated group (8%), with 1% Grade 3-4 events.<\/p>\n \nObserve patients closely for hypersensitivity reactions. Severe hypersensitivity, including anaphylaxis and fatal events, has been observed in patients treated with pertuzumab products. Angioedema has been described in postmarketing reports. Medications to treat such reactions, as well as emergency equipment, should be available for immediate use prior to administration of POHERDY.<\/p>\n ADVERSE REACTIONS<\/b><\/p>\n Metastatic Breast Cancer<\/b><\/p>\n \nThe most common adverse reactions (>30%) with pertuzumab in combination with trastuzumab and docetaxel were diarrhea, alopecia, neutropenia, nausea, fatigue, rash, and peripheral neuropathy.<\/p>\n Neoadjuvant Treatment of Breast Cancer<\/b><\/p>\n \nThe most common adverse reactions (>30%) with pertuzumab in combination with trastuzumab and docetaxel were alopecia, diarrhea, nausea, and neutropenia.<\/p>\n \nThe most common adverse reactions (>30%) with pertuzumab in combination with trastuzumab and docetaxel when given for 3 cycles following 3 cycles of FEC were fatigue, alopecia, diarrhea, nausea, vomiting, and neutropenia.<\/p>\n \nThe most common adverse reactions (>30%) with pertuzumab in combination with TCH were fatigue, alopecia, diarrhea, nausea, vomiting, neutropenia, thrombocytopenia, and anemia.<\/p>\n \nThe most common adverse reactions (>30%) with pertuzumab in combination with trastuzumab and paclitaxel when given for 4 cycles following 4 cycles of ddAC were nausea, diarrhea, alopecia, fatigue, constipation, peripheral neuropathy, and headache.<\/p>\n \nThe most common adverse reactions (>30%) with pertuzumab in combination with trastuzumab and docetaxel when given for 4 cycles following 4 cycles of FEC were diarrhea, nausea, alopecia, asthenia, constipation, fatigue, mucosal inflammation, vomiting, myalgia, and anemia.<\/p>\n Adjuvant Treatment of Breast Cancer<\/b><\/p>\n \nThe most common adverse reactions (>30%) with pertuzumab in combination with trastuzumab and chemotherapy were diarrhea, nausea, alopecia, fatigue, peripheral neuropathy, and vomiting.<\/p>\n Before prescribing POHERDY, please read the <\/b>Prescribing Information<\/b><\/a>, including the Boxed Warning about left ventricular dysfunction and embryo-fetal toxicity.<\/b><\/p>\n About Henlius<\/span><\/b><\/p>\n \nHenlius (2696.HK) is a global biopharmaceutical company with the vision to offer high-quality, affordable and innovative biologic medicines for patients worldwide with a focus on oncology, autoimmune diseases and ophthalmic diseases.
