CAMBRIDGE, Mass.— (BUSINESS WIRE)—November 14, 2023—2seventy bio, Inc. (Nasdaq: TSVT), a leading immuno-oncology cell therapy company, today reported financial results and recent highlights for the third quarter ended September 30, 2023.
“This quarter, 2seventy completed a significant reshaping of our organization, enabling us to advance our pipeline in an efficient and more cost-effective manner. We are also supporting BMS’ efforts to return Abecma to growth through a variety of commercial and medical affairs initiatives, including adding more treatment sites and boots on the ground,” said Nick Leschly, chief kairos officer. “Collectively, we believe these measures will give us the ability to continue our mission of delivering time to patients, operate within a more disciplined cost structure and deliver value for our shareholders.”
SELECT COMMERCIAL AND FINANCIAL HIGHLIGHTS
•Third quarter Abecma U.S. revenues, as reported by Bristol Myers Squibb (BMS), were $69 million. The decline in third quarter sales was due to increased competition from other BCMA-targeted therapies in addition to the planned manufacturing maintenance in June. The Company anticipates that competitive dynamics will continue to impact Abecma sales in the fourth quarter. Based on year-to-date results and current expectations for the fourth quarter, 2seventy does not expect to achieve the original revenue guidance of $470-570 million for 2023.
•In order to restore growth in Abecma, BMS and 2seventy are focused on rapidly expanding the treating site footprint, competitively differentiating Abecma’s real-world data and safety profile, and educating on treatment sequencing and the emerging data supporting the use of Abecma before T cell engagers and antibody drug conjugates, including those targeting BCMA.
•2seventy bio and BMS share equally in all profits and losses related to development, manufacturing, and commercialization of Abecma in the United States. 2seventy bio reported collaborative arrangement revenue of $0.5 million and $48.0 million for the three months and nine months ended September 30, 2023, respectively.
•In September, the Company announced a restructuring of its business operations and research and development model to significantly reduce costs while supporting the execution of a prioritized plan for the long-term growth of the Company. This restructuring is expected to achieve $130+ million savings in 2024-2025 period.
•The Company anticipates staying within the previously-guided net cash spend range of $180-220 million for 2023.
•The Company ended the third quarter of 2023 with cash, cash equivalents and marketable securities of $284.3 million. While the Company has sufficient cash to fund current planned operations for at least 12 months, we are no longer providing specific cash runway guidance.
“While Abecma performance was impacted due to the evolving competitive landscape, we and our partners at BMS believe in the long-term potential of Abecma to meaningfully impact the lives of multiple myeloma patients. We support BMS’ efforts to improve the commercial performance for the
product,” said Chip Baird, chief operating officer. “As we gain more visibility to the commercial trajectory for Abecma, we will continue to carefully manage our cash to preserve our financial runway.”
SELECTED ABECMA DATA TO BE PRESENTED AT ASH
Oral Presentation: Idecabtagene Vicleucel (ide-cel) Versus Standard Regimens in Patients (pts) with Triple-Class Exposed (TCE) Relapsed and Refractory Multiple Myeloma (RRMM): Updated Analysis from KarMMa-3
Presenter: Paula Rodriguez-Otero
Date & Time: Monday, December 11, 4:45pm PT
In the final progression-free survival (PFS) analysis from the Phase 3 KarMMa-3 study in patients with RRMM who received 2-4 prior regimens, significantly longer PFS was maintained with ide-cel versus standard regimens. In pts who received ide-cel (n = 225) or a standard regimen (n = 126), median PFS (95% CI) was 15.7 (12.5–18.9) vs 4.4 (3.4–5.8) months, respectively. The ide-cel safety profile was consistent with previous reports, with no parkinsonism or Guillain–Barré syndrome reported. Ide-cel continued to demonstrate durable, clinically meaningful improvements in pt-reported outcomes, including symptoms, functioning, and quality of life (QOL) vs standard regimens. Interim overall survival (OS) will be included in the presentation.
Poster Presentation: Efficacy and Safety of Idecabtagene Vicleucel (ide-cel) in Patients with Clinical High-Risk Newly Diagnosed Multiple Myeloma (MM) with an Inadequate Response to Frontline Autologous Stem Cell Transplantation (ASCT): KarMMa-2 Cohort 2c Extended Follow-up
Presenters: Madhav Dhodapkar; Melissa Alsina
Date & Time: Saturday, December 9, 5:30 – 7:30 PM
In updated data from the KarMMa-2 cohort 2c study, ide-cel continued to demonstrate deep, durable responses in patients with an inadequate response to frontline ASCT. No new safety signals were observed with extended follow-up, and no deaths were reported. No patients who received lenalidomide maintenance post ide-cel experienced disease progression.
“The updated clinical data to be presented on Abecma reinforces the potential of this therapy to play an important role in earlier lines,” said Steve Bernstein, chief medical officer. “In the extended follow-up from the KarMMa-3 study, we saw responses from some patients continue to deepen. The additional data from the KarMMa-2, cohort 2c study is supportive of our registrational KarMMa-9 study in a similar patient population which is now open and enrolling. We look forward to presenting these data at ASH along with additional sub-analyses that reinforce the impact of Abecma on patient-reported outcomes, quality of life and clinical use.”
RECENT UPDATES
•MUC16 DATA PRESENTED AT SITC – In November, 2seventy presented new pre-clinical data on its MUC16-targeted CAR T-cell therapy in ovarian cancer, being developed as part of our expanded collaboration with Regeneron, in a poster presentation at the 38th Annual Meeting of the Society for Immunotherapy of Cancer (SITC). These preclinical data support the IND submission for MUC16, which is on track for end of year. The Company recently completed 270-MPH, an in-house clinical drug product manufacturing site, to more effectively support growing U.S. clinical needs. MUC16 will be the first program to be manufactured in this facility.
•EXPANSION OF PARTNERSHIP WITH JW THERAPEUTICS – In September, 2seventy and JW Therapeutics announced their intention to expand their strategic alliance. The expansion, based on the partnership that was established last year, builds upon the companies’ translational and clinical cell therapy development platform originally designed to more rapidly explore T cell-based immunotherapy therapy products in Greater China. Specifically, the companies intend to add up to two additional candidates from the 2seventy portfolio, one in solid tumor indications using T-cell receptor (TCR) based technology and a second in autoimmune disease using a CAR T cell approach.

ABECMA U.S. INDICATION
ABECMA (idecabtagene vicleucel) is a B-cell maturation antigen (BCMA)-directed genetically modified autologous T cell immunotherapy indicated 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.
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 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.
