The supplemental Biologics License Application for Abecma in this indication remains under review with the FDA; Abecma has been approved in Japan and Switzerland and received a positive CHMP Opinion by the European Medicines Agency based on KarMMa-3 PRINCETON, N.J. & CAMBRIDGE, Mass.--(BUSINESS WIRE)-- Bristol Myers Squibb Company (NYSE: BMY) and 2seventy bio, Inc. (Nasdaq: TSVT) today announced that the U.S. Food and Drug Administration (FDA) Oncologic Drugs Advisory Committee (ODAC) voted positively (8-3) that Abecma (idecabtagene vicleucel) demonstrated a favorable benefit/risk pro patients with triple-class exposed relapsed or refractory multiple myeloma based on results from the pivotal Phase 3 KarMMa-3 study, including the key secondary endpoint of overall survival. The recommendation from the ODAC will be considered by the FDA during its ongoing review of the supplemental Biologics License Application (sBLA) for Abecma for this patient population. The FDA has not yet assigned a new target action date for review of the sBLA. “We are extremely pleased with the positive outcome of the ODAC meeting, which recognizes the favorable benefit/risk pro Abecma, and based on results from the KarMMa-3 study, we are confident in the significant clinical benefit that Abecma delivers for patients with triple-class exposed relapsed or refractory multiple myeloma, an incurable disease with no clear effective standard of care in earlier lines of therapy,” said Anne Kerber, senior vice president, head of Late Clinical Development, Hematology, Oncology and Cell Therapy, Bristol Myers Squibb. “We look forward to working with the FDA as it completes review of our sBLA in order to bring this potentially transformative therapy to more patients in need.” “The favorable and supportive outcome of the ODAC meeting brings us another step closer to expanding the benefits of Abecma to myeloma patients earlier in their treatment course,” said Anna Truppel-Hartmann, senior vice president, Clinical Research and Development, 2seventy bio. “We believe in the strength of the KarMMa-3 data and remain committed to increasing treatment options and improving outcomes for patients living with multiple myeloma.” The positive vote from the ODAC followed discussion of the interim overall survival data from the KarMMa-3 study which was presented at the 2023 American Society of Hematology (ASH) Annual Meeting and Exposition in December 2023. “With patients becoming triple-class exposed earlier in the multiple myeloma treatment paradigm, it is critical that new treatment options with the potential to improve long-term outcomes are available as early as possible,” said Sagar Lonial, MD, FACP, professor and chair, Department of Hematology & Medical Oncology, Emory University School of Medicine, chief medical officer, Winship Cancer Institute of Emory University. “We are thankful that today’s ODAC vote recognizes this unmet need and helps to advance ide-cel, a novel treatment option with demonstrated clinically meaningful benefit, for patients with triple-class exposed relapsed or refractory multiple myeloma.” Abecma was recently approved in Japan and Switzerland for patients with relapsed and/or refractory multiple myeloma who have received at least two prior therapies, including an immunomodulatory agent, a proteasome inhibitor, and an anti-CD38 antibody based on the KarMMa-3 study, making it the first CAR T cell therapy to receive regulatory approval for use in earlier lines of therapy for patients with relapsed or refractory multiple myeloma. Abecma also received a positive opinion from the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) for the extension of indication to include the treatment of patients with triple-class exposed relapsed and refractory multiple myeloma after at least two prior therapies, including an immunomodulatory agent, a proteasome inhibitor and an anti-CD38 antibody and have demonstrated disease progression on the last therapy. About Abecma Abecma is a CAR T cell therapy that recognizes and binds to the B-cell maturation antigen (BCMA) on the surface of multiple myeloma cells leading to CAR T cell proliferation, cytokine secretion, and subsequent cytolytic killing of BCMA-expressing cells. Abecma is the first-in-class BCMA-directed CAR T cell immunotherapy approved by the U.S. FDA for the treatment of adult patients with relapsed or refractory multiple myeloma after four or more prior lines of therapy, including an immunomodulatory agent, a proteasome inhibitor, and an anti-CD38 monoclonal antibody. Please see the Important Safety Information section below, including Boxed WARNINGS for Abecma regarding CRS, neurologic toxicities, Hemophagocytic Lymphohistiocytosis/Macrophage Activation Syndrome and Prolonged Cytopenia. Abecma is being jointly developed and commercialized in the U.S. as part of a Co-Development, Co-Promotion, and Profit Share Agreement between Bristol Myers Squibb and 2seventy bio. Abecma is also approved in the European Union, Switzerland, Japan, the United Kingdom and Israel for adult patients with triple-class exposed relapsed or refractory multiple myeloma after three to four or more prior lines of therapy. Bristol Myers Squibb assumes sole responsibility for Abecma drug product manufacturing and commercialization outside of the U.S. The companies’ broad clinical development program for Abecma includes ongoing and planned clinical studies (KarMMa-2, KarMMa-9) for patients with multiple myeloma.

U.S. Important Safety Information BOXED WARNING: CYTOKINE RELEASE SYNDROME, NEUROLOGIC TOXICITIES, HLH/MAS, AND PROLONGED CYTOPENIA Cytokine Release Syndrome (CRS), including fatal or life-threatening reactions, occurred in patients following treatment with ABECMA. Do not administer ABECMA to patients with active infection or inflammatory disorders. Treat severe or life-threatening CRS with tocilizumab or tocilizumab and corticosteroids. Neurologic Toxicities, which may be severe or life-threatening, occurred following treatment with ABECMA, including concurrently with CRS, after CRS resolution, or in the absence of CRS. Monitor for neurologic events after treatment with ABECMA. Provide supportive care and/or corticosteroids as needed. Hemophagocytic Lymphohistiocytosis/Macrophage Activation Syndrome (HLH/MAS) including fatal and life-threatening reactions, occurred in patients following treatment with ABECMA. HLH/MAS can occur with CRS or neurologic toxicities. Prolonged Cytopenia with bleeding and infection, including fatal outcomes following stem cell transplantation for hematopoietic recovery, occurred following treatment with ABECMA. ABECMA is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the ABECMA REMS. WARNINGS AND PRECAUTIONS: Cytokine Release Syndrome (CRS): CRS, including fatal or life-threatening reactions, occurred following treatment with ABECMA in 85% (108/127) of patients. Grade 3 or higher CRS occurred in 9% (12/127) of patients, with Grade 5 CRS reported in one (0.8%) patient. The median time to onset of CRS, any grade, was 1 day (range: 1 - 23 days) and the median duration of CRS was 7 days (range: 1 - 63 days). The most common manifestations included pyrexia, hypotension, tachycardia, chills, hypoxia, fatigue, and headache. Grade 3 or higher events that may be associated with CRS include hypotension, hypoxia, hyperbilirubinemia, hypofibrinogenemia, acute respiratory distress syndrome (ARDS), atrial fibrillation, hepatocellular injury, metabolic acidosis, pulmonary edema, multiple organ dysfunction syndrome, and HLH/MAS. Identify CRS based on clinical presentation. Evaluate for and treat other causes of fever, hypoxia, and hypotension. CRS has been reported to be associated with findings of HLH/MAS, and the physiology of the syndromes may overlap. In patients with progressive symptoms of CRS or refractory CRS despite treatment, evaluate for evidence of HLH/MAS. Fifty four percent (68/127) of patients received tocilizumab (single dose: 35%; more than 1 dose: 18%). Overall, 15% (19/127) of patients received at least 1 dose of corticosteroids for treatment of CRS. All patients that received corticosteroids for CRS received tocilizumab. Ensure that a minimum of 2 doses of tocilizumab are available prior to infusion of ABECMA. Monitor patients at least daily for 7 days following ABECMA infusion at the REMS-certified healthcare facility for signs or symptoms of CRS and monitor patients for signs or symptoms of CRS for at least 4 weeks after ABECMA infusion. At the first sign of CRS, institute treatment with supportive care, tocilizumab and/or corticosteroids as indicated. Counsel patients to seek immediate medical attention should signs or symptoms of CRS occur at any time. Neurologic Toxicities: Neurologic toxicities, which may be severe or life-threatening, occurred following treatment with ABECMA in 28% (36/127) of patients receiving ABECMA, including Grade 3 in 4% (5/127) of patients. One patient had ongoing Grade 2 neurotoxicity at the time of death. Two patients had ongoing Grade 1 tremor at the time of data cutoff. The median time to onset of neurotoxicity was 2 days (range: 1 - 42 days). CAR T cell-associated neurotoxicity resolved in 92% (33/36) of patients with a median time to resolution of 5 days (range: 1 - 61 days). The median duration of neurotoxicity was 6 days (range: 1 - 578) in all patients including 3 patients with ongoing neurotoxicity. Thirty-four patients with neurotoxicity had CRS with onset in 3 patients before, 29 patients during, and 2 patients after CRS. The most frequently reported manifestations of CAR T cell-associated neurotoxicity include encephalopathy, tremor, aphasia, and delirium. Grade 4 neurotoxicity and cerebral edema in 1 patient, Grade 3 myelitis, and Grade 3 parkinsonism have been reported with ABECMA in another study in multiple myeloma. Monitor patients at least daily for 7 days following ABECMA infusion at the REMS-certified healthcare facility for signs or symptoms of neurologic toxicities and monitor patients for signs or symptoms of neurologic toxicities for at least 4 weeks after ABECMA infusion and treat promptly. Rule out other causes of neurologic symptoms. Neurologic toxicity should be managed with supportive care and/or corticosteroids as needed. Counsel patients to seek immediate medical attention should signs or symptoms occur at any time. Hemophagocytic Lymphohistiocytosis (HLH)/Macrophage Activation Syndrome (MAS): HLH/MAS occurred in 4% (5/127) of patients receiving ABECMA. One patient developed fatal multi-organ HLH/MAS with CRS and another patient developed fatal bronchopulmonary aspergillosis with contributory HLH/MAS. Three cases of Grade 2 HLH/MAS resolved. All events of HLH/MAS had onset within 10 days of receiving ABECMA with a median onset of 7 days (range: 4 - 9 days) and occurred in the setting of ongoing or worsening CRS. Two patients with HLH/MAS had overlapping neurotoxicity. The manifestations of HLH/MAS include hypotension, hypoxia, multiple organ dysfunction, renal dysfunction, and cytopenia. HLH/MAS is a potentially life-threatening condition with a high mortality rate if not recognized early and treated. Treatment of HLH/MAS should be administered per institutional guidelines. ABECMA REMS: Due to the risk of CRS and neurologic toxicities, ABECMA is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the ABECMA REMS. Further information is available at or 1-888-423-5436. Hypersensitivity Reactions: Allergic reactions may occur with the infusion of ABECMA. Serious hypersensitivity reactions, including anaphylaxis, may be due to dimethyl sulfoxide (DMSO) in ABECMA. Infections: ABECMA should not be administered to patients with active infections or inflammatory disorders. Severe, life-threatening, or fatal infections occurred in patients after ABECMA infusion. Infections (all grades) occurred in 70% of patients. Grade 3 or 4 infections occurred in 23% of patients. Overall, 4 patients had Grade 5 infections (3%); 2 patients (1.6%) had Grade 5 events of pneumonia, 1 patient (0.8%) had Grade 5 bronchopulmonary aspergillosis, and 1 patient (0.8%) had cytomegalovirus (CMV) pneumonia associated with Pneumocystis jirovecii. Monitor patients for signs and symptoms of infection before and after ABECMA infusion and treat appropriately. Administer prophylactic, pre-emptive, and/or therapeutic antimicrobials according to standard institutional guidelines. Febrile neutropenia was observed in 16% (20/127) of patients after ABECMA infusion and may be concurrent with CRS. In the event of febrile neutropenia, evaluate for infection and manage with broad-spectrum antibiotics, fluids, and other supportive care. Viral Reactivation: CMV infection resulting in pneumonia and death has occurred following ABECMA administration. Monitor and treat for CMV reactivation in accordance with clinical guidelines. Hepatitis B virus (HBV) reactivation, in some cases resulting in fulminant hepatitis, hepatic failure, and death, can occur in patients treated with drugs directed against plasma cells. Perform screening for CMV, HBV, hepatitis C virus (HCV), and human immunodeficiency virus (HIV) in accordance with clinical guidelines before collection of cells for manufacturing. Prolonged Cytopenias: In the clinical study, 41% of patients (52/127) experienced prolonged Grade 3 or 4 neutropenia and 49% (62/127) experienced prolonged Grade 3 or 4 thrombocytopenia that had not resolved by Month 1 following ABECMA infusion. In 83% (43/52) of patients who recovered from Grade 3 or 4 neutropenia after Month 1, the median time to recovery from ABECMA infusion was 1.9 months. In 65% (40/62) of patients who recovered from Grade 3 or 4 thrombocytopenia, the median time to recovery was 2.1 months. Three patients underwent stem cell therapy for hematopoietic reconstitution due to prolonged cytopenia. Two of the three patients died from complications of prolonged cytopenia. Monitor blood counts prior to and after ABECMA infusion. Manage cytopenia with myeloid growth factor and blood product transfusion support. Hypogammaglobulinemia: Hypogammaglobulinemia was reported as an adverse event in 21% (27/127) of patients; laboratory IgG levels fell below 500 mg/dl after infusion in 25% (32/127) of patients treated with ABECMA. Monitor immunoglobulin levels after treatment with ABECMA and administer IVIG for IgG <400 mg/dl. Manage appropriately per local institutional guidelines, including infection precautions and antibiotic or antiviral prophylaxis. The safety of immunization with live viral vaccines during or after ABECMA treatment has not been studied. Vaccination with live virus vaccines is not recommended for at least 6 weeks prior to the start of lymphodepleting chemotherapy, during ABECMA treatment, and until immune recovery following treatment with ABECMA. Secondary Malignancies: Patients treated with ABECMA may develop secondary malignancies. Monitor life-long for secondary malignancies. If a secondary malignancy occurs, contact Bristol-Myers Squibb at 1-888-805-4555 to obtain instructions on patient samples to collect for testing of secondary malignancy of T cell origin. Effects on Ability to Drive and Operate Machinery: Due to the potential for neurologic events, patients receiving ABECMA are at risk for altered or decreased consciousness or coordination in the 8 weeks following ABECMA infusion. Advise patients to refrain from driving and engaging in hazardous occupations or activities, such as operating heavy or potentially dangerous machinery, during this initial period. Adverse Reactions: The most common nonlaboratory adverse reactions include CRS, infections – pathogen unspecified, fatigue, musculoskeletal pain, hypogammaglobulinemia, diarrhea, upper respiratory tract infection, nausea, viral infections, encephalopathy, edema, pyrexia, cough, headache, and decreased appetite.

CAMBRIDGE, Mass.--( BUSINESS WIRE )-- 2seventy bio, Inc . (Nasdaq: TSVT), a leading immuno-oncology cell therapy company, today reported financial results and recent highlights for the fourth quarter and full year ended December 31, 2023. “In the past weeks and months, 2seventy has made significant changes to our business and cost structure designed to optimize our ability to unlock value for Abecma ,” said Chip Baird, incoming CEO. “While Abecma experienced continued competitive headwinds in the fourth quarter, we and our partners at Bristol Myers Squibb are approaching critical milestones that we believe will shift Abecma back to growth, including the upcoming ODAC meeting next week to review our sBLA for Abecma in earlier lines. Given the strength of the KarMMa-3 data, which was presented at the American Society of Hematology Annual Meeting and Exposition last year, and the positive response from regulators in other geographies, we have confidence in the outcome of the ODAC meeting and potential for approval in the third line setting. With the potential for this expanded label and continuing commercial execution, in addition to the ongoing KarMMa-9 study in newly-diagnosed patients with inadequate response to transplant, we have confidence in Abecma ’s role as an important treatment option for patients living with multiple myeloma.” ABECMA COMMERCIAL AND REGULATORY HIGHLIGHTS Fourth quarter Abecma U.S. revenues, as reported by Bristol Myers Squibb (BMS), were $56 million. The decline in fourth quarter sales was due to ongoing competition from other BCMA-targeted therapies. We anticipate that commercial performance for the first part of 2024 will continue to be impacted by competitive dynamics until the potential expansion of the label to the third-line (3L) setting. In order to restore growth in Abecma , we and BMS are focused on progressing into earlier lines of therapy, rapidly expanding the site footprint and competitively differentiating Abecma’s safety and efficacy profile with real-world data. The supplemental biologic license application (sBLA) for Abecma based on the KarMMa-3 clinical study will be reviewed at a meeting of the U.S. FDA’s Oncologic Drugs Advisory Committee (ODAC) on March 15, 2024. If approved, this would expand the Abecma label into the larger 3L setting. We and BMS are prepared to meet the anticipated increased demand based on the larger eligible patient population and anticipate continuing to deliver Abecma consistently, on-time and in-spec. We and BMS share equally in all profits and losses related to development, manufacturing, and commercialization of Abecma in the U.S. We reported collaborative arrangement revenue of $2.0 million related to our collaboration with BMS for the three months ended December 31, 2023, and collaborative arrangement revenue of $50.0 million related to our collaboration with BMS for the twelve months ended December 31, 2023. ABECMA CLINICAL HIGHLIGHTS At the 65th American Society of Hematology (ASH) Annual Meeting and Exposition in December 2023, we and BMS presented data from the KarMMa-3 and KarMMa-2, cohort 2c studies of Abecma . In KarMMa-3, with a median follow-up of more than 30 months, Abecma maintained a 51% reduction in risk of disease progression or death with median PFS of 13.8 months compared with 4.4 months for standard regimens in triple class exposed and refractory patients exposed to 2-4 prior lines of therapy. Responses were significantly improved with Abecma and continued to deepen over time with a complete response rate of 44% vs. 5% for standard regimens with consistent benefit observed across subgroups. In the KarMMa-3 study, the well-established safety profile of Abecma remained consistent with generally predictable and mostly low-grade occurrences of cytokine release syndrome and neurotoxicity. There were no new CRS or iiNT events with ide-cel since the interim analysis and no parkinsonism or Guillain-Barré syndrome were reported. No secondary primary malignancies of T-cell origin were reported in the ide-cel arm. No new safety signals. The Patient Related Outcomes in KarMMa-3 demonstrated clinically meaningful Health Related Quality of Life benefits, including key multiple myeloma symptoms and functioning domains, with a single infusion of Abecma treatment compared with standard regimens treatment in patients with triple class exposed relapsed and refractory multiple myeloma. In KarMMa-2, cohort 2c in newly diagnosed multiple myeloma, Abecma demonstrated deep and durable responses with a 77% complete response rate and median PFS not reached with no new safety signals with extended follow-up from the KarMMa-2 study. The KarMMa-2, cohort 2c study has a similar patient population and study design to the registration-enabling KarMMa-9 study which is currently enrolling patients. CORPORATE RESTRUCTURING In January 2024, we announced a strategic realignment of our business to focus solely on Abecma . In connection with our strategic re-alignment, we entered into an asset purchase agreement with Regeneron Pharmaceuticals, Inc. (Regeneron) to sell our oncology and autoimmune research and development programs, clinical manufacturing capabilities, and related platform technologies (the Asset Sale). The Asset Sale continues to be on track for closing in the first half of 2024. These changes are expected to yield annual savings of approximately $150 million in 2024 and approximately $200 million in 2025, inclusive of one-time cash restructuring costs of approximately $8 - 10 million. We expect to have extended cash runway beyond 2027. UPCOMING ANTICIPATED MILESTONES FDA decision on the sBLA for Abecma in 3L multiple myeloma is anticipated following the ODAC meeting on March 15, 2024 Close of the Asset Sale to Regeneron expected in the first half of 2024 SELECT FOURTH QUARTER AND FULL YEAR FINANCIAL RESULTS Total revenues were $10.7 million for the three months ended December 31, 2023, compared to $56.2 million for the three months ended December 31, 2022.

One patient had ongoing Grade 2 neurotoxicity at the time of death. Two patients had ongoing Grade 1 tremor at the time of data cutoff. The median time to onset of neurotoxicity was 2 days (range: 1 - 42 days). CAR T cell-associated neurotoxicity resolved in 92% (33/36) of patients with a median time to resolution of 5 days (range: 1 - 61 days). The median duration of neurotoxicity was 6 days (range: 1 - 578) in all patients including 3 patients with ongoing neurotoxicity. Thirty-four patients with neurotoxicity had CRS with onset in 3 patients before, 29 patients during, and 2 patients after CRS. The most frequently reported manifestations of CAR T cell-associated neurotoxicity include encephalopathy, tremor, aphasia, and delirium. Grade 4 neurotoxicity and cerebral edema in 1 patient, Grade 3 myelitis, and Grade 3 parkinsonism have been reported with ABECMA in another study in multiple myeloma. Monitor patients at least daily for 7 days following ABECMA infusion at the REMS-certified healthcare facility for signs or symptoms of neurologic toxicities and monitor patients for signs or symptoms of neurologic toxicities for at least 4 weeks after ABECMA infusion and treat promptly. Rule out other causes of neurologic symptoms. Neurologic toxicity should be managed with supportive care and/or corticosteroids as needed. Counsel patients to seek immediate medical attention should signs or symptoms occur at any time. Hemophagocytic Lymphohistiocytosis (HLH)/Macrophage Activation Syndrome (MAS): HLH/MAS occurred in 4% (5/127) of patients receiving ABECMA . One patient developed fatal multi-organ HLH/MAS with CRS and another patient developed fatal bronchopulmonary aspergillosis with contributory HLH/MAS. Three cases of Grade 2 HLH/MAS resolved. All events of HLH/MAS had onset within 10 days of receiving ABECMA with a median onset of 7 days (range: 4 - 9 days) and occurred in the setting of ongoing or worsening CRS. Two patients with HLH/MAS had overlapping neurotoxicity. The manifestations of HLH/MAS include hypotension, hypoxia, multiple organ dysfunction, renal dysfunction, and cytopenia. HLH/MAS is a potentially life-threatening condition with a high mortality rate if not recognized early and treated. Treatment of HLH/MAS should be administered per institutional guidelines. ABECMA REMS: Due to the risk of CRS and neurologic toxicities, ABECMA is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the ABECMA REMS. Further information is available at www.AbecmaREMS.com or 1-888-423-5436. Hypersensitivity Reactions: Allergic reactions may occur with the infusion of ABECMA . Serious hypersensitivity reactions, including anaphylaxis, may be due to dimethyl sulfoxide (DMSO) in ABECMA . Infections: ABECMA should not be administered to patients with active infections or inflammatory disorders. Severe, life-threatening, or fatal infections occurred in patients after ABECMA infusion. Infections (all grades) occurred in 70% of patients. Grade 3 or 4 infections occurred in 23% of patients. Overall, 4 patients had Grade 5 infections (3%); 2 patients (1.6%) had Grade 5 events of pneumonia, 1 patient (0.8%) had Grade 5 bronchopulmonary aspergillosis, and 1 patient (0.8%) had cytomegalovirus (CMV) pneumonia associated with Pneumocystis jirovecii. Monitor patients for signs and symptoms of infection before and after ABECMA infusion and treat appropriately. Administer prophylactic, pre-emptive, and/or therapeutic antimicrobials according to standard institutional guidelines. Febrile neutropenia was observed in 16% (20/127) of patients after ABECMA infusion and may be concurrent with CRS. In the event of febrile neutropenia, evaluate for infection and manage with broad-spectrum antibiotics, fluids, and other supportive care. Viral Reactivation: CMV infection resulting in pneumonia and death has occurred following ABECMA administration. Monitor and treat for CMV reactivation in accordance with clinical guidelines. Hepatitis B virus (HBV) reactivation, in some cases resulting in fulminant hepatitis, hepatic failure, and death, can occur in patients treated with drugs directed against plasma cells. Perform screening for CMV, HBV, hepatitis C virus (HCV), and human immunodeficiency virus (HIV) in accordance with clinical guidelines before collection of cells for manufacturing. Prolonged Cytopenias: In the clinical study, 41% of patients (52/127) experienced prolonged Grade 3 or 4 neutropenia and 49% (62/127) experienced prolonged Grade 3 or 4 thrombocytopenia that had not resolved by Month 1 following ABECMA infusion. In 83% (43/52) of patients who recovered from Grade 3 or 4 neutropenia after Month 1, the median time to recovery from ABECMA infusion was 1.9 months. In 65% (40/62) of patients who recovered from Grade 3 or 4 thrombocytopenia, the median time to recovery was 2.1 months. Three patients underwent stem cell therapy for hematopoietic reconstitution due to prolonged cytopenia. Two of the three patients died from complications of prolonged cytopenia. Monitor blood counts prior to and after ABECMA infusion. Manage cytopenia with myeloid growth factor and blood product transfusion support. Hypogammaglobulinemia: Hypogammaglobulinemia was reported as an adverse event in 21% (27/127) of patients; laboratory IgG levels fell below 500 mg/dl after infusion in 25% (32/127) of patients treated with ABECMA . Monitor immunoglobulin levels after treatment with ABECMA and administer IVIG for IgG <400 mg/dl. Manage appropriately per local institutional guidelines, including infection precautions and antibiotic or antiviral prophylaxis. The safety of immunization with live viral vaccines during or after ABECMA treatment has not been studied. Vaccination with live virus vaccines is not recommended for at least 6 weeks prior to the start of lymphodepleting chemotherapy, during ABECMA treatment, and until immune recovery following treatment with ABECMA . Secondary Malignancies: Patients treated with ABECMA may develop secondary malignancies. Monitor life-long for secondary malignancies. If a secondary malignancy occurs, contact Bristol-Myers Squibb at 1-888-805-4555 to obtain instructions on patient samples to collect for testing of secondary malignancy of T cell origin. Effects on Ability to Drive and Operate Machinery: Due to the potential for neurologic events, patients receiving ABECMA are at risk for altered or decreased consciousness or coordination in the 8 weeks following ABECMA infusion. Advise patients to refrain from driving and engaging in hazardous occupations or activities, such as operating heavy or potentially dangerous machinery, during this initial period. Adverse Reactions: The most common nonlaboratory adverse reactions include CRS, infections – pathogen unspecified, fatigue, musculoskeletal pain, hypogammaglobulinemia, diarrhea, upper respiratory tract infection, nausea, viral infections, encephalopathy, edema, pyrexia, cough, headache, and decreased appetite.

A Labeler project capable of diagnosing specific diseases from image readings written in natural language. Capable of identifying a total of 13 diseases with high incidence rates and importance, including fractures, pleural lesions, and pneumothorax. Recorded an accuracy of 90.39%, higher than other models, when measuring the accuracy of 10 diagnosed diseases. SEOUL, South Korea, Feb. 27, 2024 /PRNewswire/ -- On the 16th, Kakao Brain released a medical image labeler project on GitHub, capable of diagnosing specific diseases from chest X-ray image draft readings. The Labeler Project is a research and development initiative that extracts specific disease names from readings written in unstructured natural language, such as bullet format. It features the ability to identify and diagnose a total of 13 diseases with high incidence rates and importance, such as fractures, pleural lesions, and pneumothorax, based on chest X-rays. For example, when a user inputs a reading written in natural language, the reading is analyzed, and the user is notified of positive/negative results for 13 diseases. Aiming to contribute to the improvement of medical diagnoses, Kakao Brain initiated research on a labeler project that extracts specific disease names more accurately and efficiently than models previously released by other companies. This project has also been internally used to validate and study the performance of Kakao Brain's chest X-ray draft reading technology. Kakao Brain tested the accuracy of 10 diagnosed diseases, such as fractures, pneumothorax, and pulmonary edema. Kakao Brain's Labeler project recorded an accuracy rate of 90.39%, significantly higher than other companies' models (about 76%). Kakao Brain unveiled the Labeler project on GitHub and published a paper titled 'CheX-GPT: Harnessing Large Language Models for Enhanced Chest X-ray Report Labeling' on arXiv, an open-access archive. Meanwhile, Kakao Brain is striving to share AI technology know-how and create new value in line with Kakao and the community's core value of 'a better world created by technology.' The unveiling of the Labeler project is also aimed at promoting the AI open-source ecosystem, exemplified by the open-source project 'Honeybee' (tentative name) released in January. Kim Il-du, CEO of Kakao Brain, stated, "We plan to release a test set we created so that many researchers can use Kakao Brain's Labeler project as a benchmark for testing." He also added, "We plan to further improve the performance of the labeler project by utilizing our language model and incorporating additional chest X-ray data."
