Brentuximab Vedotin

First-ever immunotherapy combination approved in Europe for adult and adolescent patients, ages 12 and older, with previously untreated Stage III or IV classical Hodgkin Lymphoma (cHL) PRINCETON, N.J.--(BUSINESS WIRE)-- $BMY #HodgkinLymphoma -- Bristol Myers Squibb (NYSE: BMY) today announced that the European Commission (EC) has approved Opdivo ® (nivolumab) in combination with doxorubicin, vinblastine and dacarbazine (AVD) for the treatment of adult and adolescent patients 12 years of age and older with previously untreated Stage III or IV classical Hodgkin Lymphoma (cHL). This approval marks a significant milestone, establishing the Opdivo plus AVD combination as the first immunotherapy-based regimen available in the European Union (EU) for newly diagnosed advanced cHL. 1 This new EC approval reinforces the expanding impact of Opdivo in cHL, building upon the U.S. Food and Drug Administration (FDA) approval of Opdivo in combination with AVD for previously untreated Stage III or IV cHL in adults and pediatric patients 12 years and older, granted in March 2026. 2 Earlier this year, the EC also approved Opdivo in combination with brentuximab vedotin for the treatment of children 5 years of age and older, adolescents, and adults up to 30 years of age with relapsed or refractory cHL after one prior line of therapy. 1 “Today’s approval of Opdivo in combination with AVD for previously untreated advanced classical Hodgkin Lymphoma marks an important advancement for patients in the European Union, 1 ” said Monica Shaw, MD, senior vice president of Oncology Commercialization, Bristol Myers Squibb. “For decades, patients newly diagnosed with this aggressive blood cancer have faced intensive treatment approaches. 3,4 This approval underscores the benefit and critical role of immunotherapy-based approaches in hematologic cancers like cHL and reflects our continued commitment to bringing these innovative options to patients earlier in their treatment journey across cancer types.” The EC approval is based on data from the Phase 3 SWOG 1826 (Study CA2098UT) which demonstrated a 58% reduction in the risk of disease progression or death with Opdivo in combination with AVD versus brentuximab vedotin plus AVD, as determined per investigator (Hazard Ratio [HR] 0.42; 95% Confidence Interval [CI] 0.27-0.67; P =<0.0001).The trial demonstrated a statistically significant improvement in the primary endpoint of progression-free survival (PFS), based on a median follow-up of 13.7 months in the intent to treat population. After a median follow-up of 36.7 months, the median overall survival (OS) had not been reached in either treatment arm with a total of 26 deaths: 9 (1.8%) deaths in the Opdivo in combination with AVD arm and 17 (3.4%) deaths in the standard of care over brentuximab vedotin plus AVD arm. 5 “For patients with newly diagnosed Stage III or IV classical Hodgkin Lymphoma, finding an effective and tolerable first-line treatment remains crucial to achieving long-term remission, especially for adolescents and the elderly,” said Franck Morschhauser, MD, PhD, Professor of Hematology at the University of Lille and Hospital Claude Huriez. “The SWOG 1826 study provided compelling data demonstrating that nivolumab-based combination therapy significantly improved progression-free survival compared with the standard of care. The availability of the first-ever IO combination in this earlier setting and across a broad spectrum of ages offers a potentially practice-changing approach to the treatment of frontline cHL.” This approval by the EC for Opdivo plus AVD for the treatment of adult and adolescent patients 12 years of age and older with previously untreated Stage III or IV cHL is valid in all 27 member states of the EU, as well as Iceland, Liechtenstein and Norway. In addition to this approval in cHL, Opdivo- based options are also approved for treatment of multiple tumor types in the EU. Bristol Myers Squibb thanks the SWOG Cancer Research Network and its investigators for leading the Phase 3 SWOG 1826 (CA2098UT) trial and the patients for their important contributions to this study. About SWOG 1826 (CA2098UT) SWOG 1826, also known as CA2098UT, is a randomized, multicenter, Phase 3 study evaluating Opdivo ® (nivolumab) in combination with doxorubicin, vinblastine and dacarbazine (AVD) for adult and pediatric (12 years and older) patients with previously untreated Stage III or IV classical Hodgkin Lymphoma (cHL). 3 The study is designed to assess progression-free survival as the primary endpoint, with key secondary endpoints that include overall survival and other measures of efficacy and safety. 3 The SWOG 1826 study is sponsored by the National Cancer Institute (NCI), part of the National Institutes of Health (NIH) under a Cooperative Research and Development Agreement with Bristol Myers Squibb and conducted in the NCI National Clinical Trials Network (NCTN) led by the SWOG Cancer Research Network in collaboration with the Children’s Oncology Group (COG). 3 It is the largest cHL study conducted in the NCTN. 3 Bristol Myers Squibb co-sponsored the study and supplied Opdivo to the NCI through a Cooperative Research and Development Agreement. 3 Select Safety Pro SWOG 1826 (CA2098UT) Serious adverse reactions occurred in 39% of patients receiving Opdivo in combination with doxorubicin, vinblastine and dacarbazine (AVD) (n=490). The most frequent serious adverse reactions reported in ≥5% patients who received Opdivo in combination with AVD were neutropenia (7%), pyrexia (7%), febrile neutropenia (6%), and nausea (6%). Fatal adverse reactions occurred in 3 patients (0.6%), all from sepsis. The most common adverse reactions were nausea (70%), neutropenia (61%), fatigue (59%), anemia (51%), constipation (49%), leukopenia (44%), musculoskeletal pain (42%), transaminases increase (41%), peripheral neuropathy (41%), vomiting (33%), and stomatitis (30%). About Classical Hodgkin Lymphoma Hodgkin lymphoma (HL), also known as Hodgkin disease, is a cancer that starts in white blood cells called lymphocytes, which are part of the body’s immune system. 6 HL is the most common cancer diagnosed in adolescents (ages 15-19). 7 It is most often diagnosed in early adulthood (ages 20-39) and late adulthood (older than 55 years of age). 8 Classical Hodgkin lymphoma is the most common type of HL, accounting for 95% of cases. 9 Despite progress in frontline therapy, advanced-stage HL still carries a substantial risk of relapse, highlighting the need for innovative approaches that deliver durable remission for patients. 8 About Opdivo Opdivo is a programmed death-1 (PD-1) immune checkpoint inhibitor that is designed to uniquely harness the body’s own immune system to help restore anti-tumor immune response. By harnessing the body’s own immune system to fight cancer, Opdivo has become an important treatment option across multiple cancers. Opdivo’s leading global development program is based on Bristol Myers Squibb’s scientific expertise in the field of Immuno-Oncology and includes a broad range of clinical trials across all phases, including Phase 3, in a variety of tumor types. To date, the Opdivo clinical development program has treated more than 35,000 patients. The Opdivo trials have contributed to gaining a deeper understanding of the potential role of biomarkers in patient care, particularly regarding how patients may benefit from Opdivo across the continuum of PD-L1 expression. In July 2014, Opdivo was the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world. Opdivo is currently approved in more than 65 countries, including the United States, the European Union, Japan and China. In October 2015, the Company’s Opdivo and Yervoy combination regimen was the first Immuno-Oncology combination to receive regulatory approval for the treatment of metastatic melanoma and is currently approved in more than 50 countries, including the United States and the European Union.

IMPORTANT SAFETY INFORMATION Severe and Fatal Immune-Mediated Adverse Reactions Immune-mediated adverse reactions listed herein may not include all possible severe and fatal immune-mediated adverse reactions. Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue. While immune-mediated adverse reactions usually manifest during treatment, they can also occur after discontinuation of OPDIVO or YERVOY. Early identification and management are essential to ensure safe use of OPDIVO and YERVOY. Monitor for signs and symptoms that may be clinical manifestations of underlying immune-mediated adverse reactions. Evaluate clinical chemistries including liver enzymes, creatinine, adrenocorticotropic hormone (ACTH) level, and thyroid function at baseline and periodically during treatment with OPDIVO and before each dose of YERVOY. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate. Withhold or permanently discontinue OPDIVO and YERVOY depending on severity (please see section 2 Dosage and Administration in the accompanying Full Prescribing Information). In general, if OPDIVO or YERVOY interruption or discontinuation is required, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose immune-mediated adverse reactions are not controlled with corticosteroid therapy. Toxicity management guidelines for adverse reactions that do not necessarily require systemic steroids (e.g., endocrinopathies and dermatologic reactions) are discussed below. Immune-Mediated Pneumonitis OPDIVO and YERVOY can cause immune-mediated pneumonitis. The incidence of pneumonitis is higher in patients who have received prior thoracic radiation. In patients receiving OPDIVO monotherapy, immune-mediated pneumonitis occurred in 3.1% (61/1994) of patients, including Grade 4 (<0.1%), Grade 3 (0.9%), and Grade 2 (2.1%). In patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg every 3 weeks, immune-mediated pneumonitis occurred in 7% (31/456) of patients, including Grade 4 (0.2%), Grade 3 (2.0%), and Grade 2 (4.4%). In patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg every 3 weeks, immune-mediated pneumonitis occurred in 3.9% (26/666) of patients, including Grade 3 (1.4%) and Grade 2 (2.6%). In NSCLC patients receiving OPDIVO 3 mg/kg every 2 weeks with YERVOY 1 mg/kg every 6 weeks, immune-mediated pneumonitis occurred in 9% (50/576) of patients, including Grade 4 (0.5%), Grade 3 (3.5%), and Grade 2 (4.0%). Four patients (0.7%) died due to pneumonitis. In Checkmate 205 and 039, pneumonitis, including interstitial lung disease, occurred in 6.0% (16/266) of patients receiving OPDIVO. Immune-mediated pneumonitis occurred in 4.9% (13/266) of patients receiving OPDIVO, including Grade 3 (n=1) and Grade 2 (n=12). Immune-Mediated Colitis OPDIVO and YERVOY can cause immune-mediated colitis, which may be fatal. A common symptom included in the definition of colitis was diarrhea. Cytomegalovirus (CMV) infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies. In patients receiving OPDIVO monotherapy, immune-mediated colitis occurred in 2.9% (58/1994) of patients, including Grade 3 (1.7%) and Grade 2 (1%). In patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg every 3 weeks, immune-mediated colitis occurred in 25% (115/456) of patients, including Grade 4 (0.4%), Grade 3 (14%) and Grade 2 (8%). In patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg every 3 weeks, immune-mediated colitis occurred in 9% (60/666) of patients, including Grade 3 (4.4%) and Grade 2 (3.7%). Immune-Mediated Hepatitis and Hepatotoxicity OPDIVO and YERVOY can cause immune-mediated hepatitis. In patients receiving OPDIVO monotherapy, immune-mediated hepatitis occurred in 1.8% (35/1994) of patients, including Grade 4 (0.2%), Grade 3 (1.3%), and Grade 2 (0.4%). In patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg every 3 weeks, immune-mediated hepatitis occurred in 15% (70/456) of patients, including Grade 4 (2.4%), Grade 3 (11%), and Grade 2 (1.8%). In patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg every 3 weeks, immune-mediated hepatitis occurred in 7% (48/666) of patients, including Grade 4 (1.2%), Grade 3 (4.9%), and Grade 2 (0.4%). OPDIVO in combination with cabozantinib can cause hepatic toxicity with higher frequencies of Grade 3 and 4 ALT and AST elevations compared to OPDIVO alone. Consider more frequent monitoring of liver enzymes as compared to when the drugs are administered as single agents. In patients receiving OPDIVO and cabozantinib, Grades 3 and 4 increased ALT or AST were seen in 11% of patients. Immune-Mediated Endocrinopathies OPDIVO and YERVOY can cause primary or secondary adrenal insufficiency, immune-mediated hypophysitis, immune-mediated thyroid disorders, and Type 1 diabetes mellitus, which can present with diabetic ketoacidosis. Withhold OPDIVO and YERVOY depending on severity (please see section 2 Dosage and Administration in the accompanying Full Prescribing Information). For Grade 2 or higher adrenal insufficiency, initiate symptomatic treatment, including hormone replacement as clinically indicated. Hypophysitis can present with acute symptoms associated with mass effect such as headache, photophobia, or visual field defects. Hypophysitis can cause hypopituitarism; initiate hormone replacement as clinically indicated. Thyroiditis can present with or without endocrinopathy. Hypothyroidism can follow hyperthyroidism; initiate hormone replacement or medical management as clinically indicated. Monitor patients for hyperglycemia or other signs and symptoms of diabetes; initiate treatment with insulin as clinically indicated. In patients receiving OPDIVO monotherapy, adrenal insufficiency occurred in 1% (20/1994), including Grade 3 (0.4%) and Grade 2 (0.6%). In patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg every 3 weeks, adrenal insufficiency occurred in 8% (35/456) of patients, including Grade 4 (0.2%), Grade 3 (2.4%), and Grade 2 (4.2%).

The New Drugs on the Horizon: Part 2 session spotlighted a human-sialidase-armed antitumor antibody, a novel CDK2 inhibitor, a molecular glue degrader, and a dual-payload antibody-drug conjugate (ADC). Session Co-chair Danette L. Daniels, PhD, of Foghorn Therapeutics, said that the 12 presentations selected for the New Drugs on the Horizon series represent a mix of modalities, including biologics, small molecules, and macrocycles, and revealed a lot of breakthrough biology. Daniels is the 2026-2028 chair of the AACR Chemistry in Cancer Research Working Group (CICR), which sponsors the New Drugs on the Horizon series. New Drugs on the Horizon: Part 1 New Drugs on the Horizon: Part 3 First presenter Jim Broderick, MD, of Palleon Pharmaceuticals, introduced HLX316/E-688, a first-in-class molecule that targets the immune checkpoint molecule B7-H3 and is armed with the human sialidase enzyme. Hypersialylation promotes cancer development by suppressing innate and adaptive antitumor immunity. Initial clinical evaluation of a first-generation untargeted sialidase dimer allowed the researchers to establish proof of mechanism and identify key limitations that hindered efficacy. This experience led to the development of HLX316/E-688 as a tumor antigen-targeted sialidase that retained in vivo tumor desialylation activity for more than seven days and showed improved preclinical activity compared with the untargeted dimer. Broderick pointed out that B7-H3 expression and hypersialylation are both present on a variety of tumor types, suggesting broad potential of HLX316/E-688 across multiple cancer patient populations. A phase I trial of HLX316/E-688 is initiating in platinum-resistant ovarian cancer, which shows high expression of B7-H3 and hypersialylation. Zainab Jagani, PhD, of Novartis Institutes for BioMedical Research, Inc., discussed ECI830, a CDK2 inhibitor, for the treatment of certain HR-positive, HER2-negative breast cancer patients. Targeting cell cycle through CDK4/6 inhibitors, in combination with endocrine therapy, represents a clinically proven strategy for HR-positive breast cancer, yet therapy resistance and progression remain a challenge, said Jagani. In particular, patients whose tumors express high levels of cyclin E have lower progression-free survival compared with patients with lower expression, and cyclin E levels increase after treatment. Jagani and team hypothesized that combined inhibition of CDK4 and CDK2, which works in complex with cyclin E, may yield more durable responses. They developed ECI830 as a potent and highly selective ATP-competitive CDK2 inhibitor that enhanced the effects of the CDK4/6 inhibitor ribociclib (Kisqali) in breast cancer cells and tumor models. Jagani added that ECI830 showed efficacy as a monotherapy in CCNE1-amplified ovarian and lung cancer models. ECI830 is currently being evaluated in a phase I clinical trial as a single agent and as part of a combination in patients with advanced HR-positive, HER2-negative breast cancer and other advanced solid tumors. Vito J. Palombella, PhD, of Triana Biomedicines, presented TRI-611, a selective molecular glue degrader of the ALK receptor tyrosine kinase that is expressed as a fusion protein in approximately 5% of cases of non-small cell lung cancer (NSCLC). Multiple tyrosine kinase inhibitors have been approved for the treatment of ALK-positive NSCLC, but chemotherapy remains the only option after progression, said Palombella. TRI-611 was designed to facilitate ALK ubiquitination and degradation through a structural motif called degron. TRI-611 treatment induced dose-dependent ALK degradation and tumor shrinking in models of NSCLC and was active against mutated forms of the EML4-ALK fusion protein that are associated with resistance to tyrosine kinase inhibition. Furthermore, TRI-611 caused tumor regression in an ALK-positive patient-derived tumor model and in intracranial tumor xenografts, highlighting its potential for the treatment of central nervous system metastases. Palombella emphasized that, due to its high selectivity and preclinical safety, TRI-611 may allow combinations with other therapeutics. TRI-611 is being studied in a phase I trial and has received Fast Track designation from the U.S. Food and Drug Administration. Megan Rice, MS, of AstraZeneca, highlighted the discovery and development of a CD30 dual-payload ADC (dpADC). Brentuximab vedotin (Adcetris) was the first CD30-targeting ADC to be approved for the initial treatment of Hodgkin lymphoma and anaplastic large-cell lymphoma (ALCL). Unfortunately, many patients relapse after treatment. DpADCs enable simultaneous delivery of two different drugs into the same cancer cells to drive more robust tumor responses, overcome drug resistance, and address tumor heterogeneity, explained Rice. CD30 dpADC combines a microtubule inhibitor and a topoisomerase I inhibitor. In vitro experiments showed that CD30 dpADC achieved specific binding to CD30-positive cells, was efficiently internalized, induced payload-driven DNA damage and cell death. Treatment with CD30 dpADC showed preclinical activity both in Hodgkin lymphoma and ALCL tumor models. Furthermore, because of reduced free-payload accumulation, CD30 dpADC treatment at clinically relevant doses demonstrated improved tolerability compared with brentuximab vedotin. Planning of a phase I clinical trial of CD30 dpADC is underway.
