Trial met the primary efficacy endpoint demonstrating non-inferiority of the incidence of acute kidney injury for INTERCEPT Red Blood Cells compared to conventional red blood cells CONCORD, Calif.--(BUSINESS WIRE)-- Cerus Corporation (Nasdaq: CERS) today announced positive topline results for ReCePI, a pivotal Phase 3 clinical trial of pathogen reduced INTERCEPT Red Blood Cells (INTERCEPT RBCs) transfused to complex cardiac surgery patients. The trial met its primary efficacy endpoint, demonstrating non-inferiority for INTERCEPT RBCs compared to conventional RBCs as measured by the incidence of acute kidney injury (AKI) following transfusion of study RBCs. AKI is a sensitive transfusion efficacy indicator of RBC tissue oxygen delivery. In transfused subjects, by modified intent to treat (mITT pre-specified primary endpoint population) the incidence of AKI was 29.3% (46/157) for INTERCEPT RBC recipients compared to 28.0% (45/161) for conventional RBC recipients, demonstrating non-inferiority of INTERCEPT RBCs compared to conventional RBCs with an upper limit of the 95% confidence interval of 10.4% compared with a non-inferiority margin of 14.0% (p = 0.001). The safety endpoint of the proportion of patients with any related treatment-emergent adverse events (TEAEs) within 28 days of last transfusion was not significantly different for INTERCEPT RBCs (2.5%) compared to conventional RBCs (0.6%) (p = 0.130). There was no clinical significance related to treatment-emergent RBC antibodies observed in five patients receiving INTERCEPT RBCs. The trial’s independent Data Safety and Monitoring Board (DSMB) evaluated these patients and was supportive of continued transfusion, having found no adverse health effects from trial transfusions. This safety endpoint is also being explored in the Company’s ongoing RedeS Phase 3 clinical trial of INTERCEPT RBCs. Cerus plans to include data from both the ReCePI and RedeS clinical trials in an integrated safety analysis as part of its planned modular premarket approval (PMA) submission. “We are extremely pleased by the positive topline results of the ReCePI clinical trial,” stated Richard Benjamin, M.D., Ph.D., Cerus’ chief medical officer and principal investigator for the ReCePI clinical trial. “The ReCePI clinical trial is a pioneering trial in the field of transfusion medicine, providing critical information about pathogen reduced INTERCEPT RBCs compared to conventional RBCs. We continue to look forward to completing the RedeS clinical trial, Cerus’ ongoing pivotal Phase 3 clinical trial for INTERCEPT RBCs enrolling a broader patient population requiring RBC transfusion for acute and chronic anemia.” “Today’s news from the ReCePI clinical trial is an important milestone for the INTERCEPT RBC program,” stated William “Obi” Greenman, Cerus’ president and chief executive officer. “We are now one meaningful step closer to potentially making pathogen reduction available for RBCs, the most commonly transfused blood component in the U.S., with approximately 11 million transfused units annually. If approved, pathogen reduced RBCs would complement our existing commercial portfolio of INTERCEPT Systems for Platelets, Plasma, and Fibrinogen Complex, providing clinicians and patients access to the benefits of pathogen inactivation across all transfused components. We are grateful to all the patients, blood centers, and physicians who participated in the ReCePI clinical trial.” Cerus anticipates initiating a modular PMA application to the U.S. Food and Drug Administration (FDA) in the second half of 2025, with the final PMA module submission planned for the second half of 2026, upon the anticipated completion of the RedeS clinical trial. Data from preclinical studies, manufacturing information, previously reported Phase 1 and Phase 2 clinical trials in the U.S., and the successfully completed Phase 3 clinical trials in the EU (STARS and SPARC) will be included in the modular PMA submission. Cerus expects the data from the ReCePI clinical trial to be presented at upcoming medical conferences as well as to be submitted for peer reviewed publication. Webcast The Company will host a webcast at 9:00 A.M. EDT this morning, during which management will discuss the results of the ReCePI clinical trial. To listen to the live webcast, please visit the Investor Relations page of the Cerus website at A replay will be available on Cerus’ website approximately three hours after the call through April 2, 2024. ABOUT ReCePI The ReCePI Phase 3 clinical trial was a prospective, multicenter, randomized, double-blinded, controlled, non-inferiority design trial (ClinicalTrials.gov: NCT03459287) to evaluate the efficacy and safety of RBCs prepared with the INTERCEPT RBC System in patients requiring transfusion for acute blood loss during complex cardiac surgery. Adult subjects at high risk of need for RBC transfusion received either conventional (control) or INTERCEPT RBCs during and for 7 days after complex cardiovascular surgery (CVS), including thoracic aorta surgery. The primary efficacy endpoint was the proportion of transfused patients with acute kidney injury (AKI) defined by increased serum creatinine (≥0.3 mg/dL or 26.5 µmol/L) from pre-transfusion baseline, within 48 hours of surgery. Safety endpoints were defined as related TEAEs through 28 days after enrollment; or antibodies with confirmed specificity to INTERCEPT RBCs through 75 days after enrollment. The ReCePI trial enrolled and randomized a total of 581 patients across 18 clinical study sites. The mITT population included 321 patients requiring RBC transfusions in the trial. Not all enrolled patients required RBC transfusion. INTERCEPT RBCs used in the ReCePI trial were produced by several blood centers in the U.S. The development program of the INTERCEPT Red Blood Cell System has been funded in part with federal funds from the Department of Health and Human Services; Administration for Strategic Preparedness and Response; BARDA, under contract number HHSO100201600009C. ABOUT THE INTERCEPT BLOOD SYSTEM FOR RED BLOOD CELLS The INTERCEPT Blood System for Red Blood Cells is designed to inactivate blood-borne pathogens and donor leukocytes in RBCs intended for transfusion. The RBC system is designed to prevent pathogen replication by using a small molecule compound added to RBC concentrates to form bonds within nucleic acids in pathogens and leukocytes that may be present in donated RBC collections. The nucleic acid targeted mechanism of action is designed to preserve the therapeutic qualities of the RBCs. RBCs, platelets, and plasma do not require nucleic acid replication for therapeutic efficacy. The RBC system is under development and is not yet approved anywhere in the world. Cerus has filed for a CE Mark for the RBC system under the Medical Device Regulation and anticipates initiating a modular PMA application submission to the FDA in the second half of 2025. ABOUT CERUS Cerus Corporation is dedicated solely to safeguarding the world’s blood supply and aims to become the preeminent global blood products company. Headquartered in Concord, California, the company develops and supplies vital technologies and pathogen-protected blood components to blood centers, hospitals, and ultimately patients who rely on safe blood.

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.

We look forward to advancing our pipeline into the clinic to develop therapies designed to target neurological diseases with high unmet medical needs.” Recent Business Highlights Prioritized Neurology Pipeline Sangamo is developing epigenetic regulation therapies to treat serious neurological diseases and novel proprietary AAV capsids designed to deliver our therapies to the intended neurological targets, including across the blood-brain barrier. Novel AAV Capsid Delivery Technology – Data demonstrated industry-leading BBB penetration and brain transduction in NHPs, with capsid-enabled delivery of zinc finger payloads targeting prion disease and tauopathies resulting in potent and widespread repression of target genes. Novel STAC-BBB capsid demonstrated robust penetration of BBB with 700-fold higher transgene expression in neurons compared to the benchmark capsid AAV9 and outperformed all other known published capsid variants evaluated in the study. STAC-BBB mediated robust expression of zinc finger cargo in neurons, with potent and widespread repression of prion and tau genes observed across key brain regions, demonstrating the potential for modification of disease progression in prion disease and various tauopathies. Visualization of gene expression in individual brain cells by RNAscope revealed highly potent repression of tau in neurons expressing the zinc finger cargo, across multiple brain regions. Capsid biodistribution pro optimal for the treatment of neurological diseases with AAV-based treatments, highlighted by the observed enrichment in the CNS and de-targeting from the liver, dorsal root ganglia (DRG) and other peripheral organs. STAC-BBB was well tolerated in NHPs, with no notable treatment related pathological findings in brain, spinal cord or peripheral tissues. We believe that STAC-BBB is manufacturable at commercial scale using standard cell culture and purification processes, is soluble using known excipients, and can be characterized using available analytics. Chronic Neuropathic Pain – Preclinical data demonstrated potent and specific repression of Nav1.7 expression without impacting other sodium channels and that zinc finger repressors (ZFRs) were well tolerated in NHPs; IND submission expected in fourth quarter of 2024. IND-enabling toxicology studies are nearing completion. An IND submission is expected in the fourth quarter of 2024. Prion Disease – Preclinical data demonstrated that AAV-delivered ZFRs significantly reduced expression of the prion protein in the brain, extended lifespan and limited formation of toxic prion aggregates in mice; CTA expected in the fourth quarter of 2025. CTA-enabling studies continue to advance. Prion-targeted zinc finger repressor, delivered via an intravenous administration of the STAC-BBB novel capsid, resulted in a dose-dependent repression of prion genes in NHPs. A CTA submission is expected in the fourth quarter of 2025. Tauopathies – Preclinical data demonstrated that AAV-delivered ZFRs significantly reduced expression of tau mRNA in brain of NHPs; intend to resume development of this program, leveraging STAC-BBB; IND submission expected as early as the fourth quarter of 2025. Intend to resume development of our previously paused tau program, leveraging the newly identified STAC-BBB capsid variant, subject to additional funding. Tau clinical-lead zinc finger repressor, delivered via an intravenous administration of the STAC-BBB novel capsid, resulted in a dose-dependent repression of tau genes in NHPs. Visualization of gene expression in individual brain cells by RNAscope revealed highly potent repression of tau in neurons expressing the zinc finger cargo across multiple brain regions. We expect the IND submission could occur as early as the fourth quarter of 2025. Other Programs Fabry Disease – Dosed total of 32 patients in Phase 1/2 STAAR study, with updated clinical data presented at 20th Annual WORLDSymposium showing sustained benefit and differentiated safety pro >; announced FDA alignment on abbreviated pathway to potential approval; actively seeking collaboration partner to advance asset toward potential registration and commercialization. Dosed seven additional patients in the dose expansion phase of the Phase 1/2 STAAR study evaluating isaralgagene civaparvovec, our wholly owned gene therapy product for the treatment of Fabry disease, for a total of 32 patients dosed to date. Presented updated clinical data at the 20th Annual WORLDSymposium in San Diego, CA in February 2024, showing that elevated levels of α-Gal A activity were sustained in all 24 patients evaluated as of the September 19, 2023 data cutoff date and accompanied by the reduction and/or long-term stabilization of lyso-Gb3 levels, with the largest reductions in plasma lyso-Gb3 seen in patients with the highest levels at baseline. All 13 patients who were withdrawn from Enzyme Replacement Therapy (ERT) remain off ERT as of March 12, 2024. In the 13 patients followed for 12-months or more after treatment, renal function remained stable, and significant improvements in overall disease severity, quality of life, and gastrointestinal symptoms compared to baseline were reported. Aligned with the FDA that data from a single, adequate, and well-controlled study may form the primary basis of approval of a BLA for isaralgagene civaparvovec, enabling a potentially abbreviated and more cost-effective pathway to BLA submission than originally anticipated. The study would enroll up to 25 patients, both male and female, without the need for a control arm. A head-to-head comparison with ERT is not part of the proposed study design deemed acceptable by the FDA. Granted PRIME eligibility from the EMA for isaralgagene civaparvovec, which aims to enhance support for the development of medicines that target an unmet medical need and is intended to optimize development plans and expedite review and approval processes. Granted Innovative Licensing and Access Pathway (ILAP) for isaralgagene civaparvovec from U.K. Medicines and Healthcare products Regulatory Agency (MHRA) which aims to accelerate time to market and facilitate access to medicines. Isaralgagene civaparvovec has already received Orphan Medicinal Product designation from the EMA as well as Orphan Drug, Fast Track and Regenerative Medicine Advanced Therapy (RMAT) designations from the FDA. Completed screening and enrollment in the Phase 1/2 STAAR study and expect to complete dosing of remaining patients in the first half of 2024. Deferring additional investments in planning for a potential registrational trial until a collaboration partnership or financing for this program is secured. Hemophilia A (Pfizer) – Pivotal data read-out in Phase 3 AFFINE trial expected in mid-2024; BLA and MAA submissions anticipated by early 2025 if pivotal readout is supportive. A pivotal readout is expected in mid-2024 in the Phase 3 AFFINE trial of giroctocogene fitelparvovec, an investigational gene therapy we are developing with Pfizer for patients with moderately severe to severe hemophilia A. Pfizer anticipates BLA and MAA submissions by early 2025 if the pivotal readout is supportive. Presented updated data with Pfizer from the Phase 1/2 ALTA study of giroctocogene fitelparvovec in an oral presentation at the 65th American Society for Hematology Annual Meeting and Exposition in December 2023. Eligible to earn from Pfizer up to $220.0 million in milestone payments upon the achievement of certain regulatory and commercial milestones for giroctocogene fitelparvovec and product sales royalties of 14% - 20% if giroctocogene fitelparvovec is approved and commercialized, subject to certain reductions. CAR-Tregs – In alignment with previously announced strategic transformation, announced winddown of the Company’s French research and manufacturing operations and a corresponding reduction in workforce; continuing to seek a potential collaboration partner or external investment in the CAR-Treg cell therapy programs. Announced a winddown of Sangamo’s French operations and a corresponding reduction in workforce, including closure of Sangamo’s cell therapy manufacturing facility and research labs in Valbonne, France, which is expected to commence in April 2024 and be complete by end of year. We expect this restructuring to result in the elimination of all roles in France (approximately 93). Dosed two additional patients in the Phase 1/2 STEADFAST study evaluating TX200, our wholly owned autologous CAR-Treg cell therapy treating patients receiving an HLA-A2 mismatched kidney from a living donor, including the first patient in the new fourth, highest dose cohort. Expect to dose up to two additional patients in the fourth highest-dose level cohort by the end of the second quarter of 2024. Plan to continue seeking a potential collaboration partner or external investment in our autologous CAR-Treg cell therapy programs. Fourth Quarter and Full Year 2023 Financial Results Consolidated net loss for the fourth quarter ended December 31, 2023 was $60.3 million, or $0.34 per share, compared to a net loss of $52.0 million, or $0.32 per share, for the same period in 2022. For the year ended December 31, 2023, consolidated net loss was $257.8 million, or $1.48 per share, compared to consolidated net loss of $192.3 million, or $1.25 per share, for the year ended December 31, 2022. Revenues Revenues for the fourth quarter ended December 31, 2023 were $2.0 million, compared to $27.2 million for the same period in 2022. The decrease of $25.2 million in revenues was primarily attributed to a decrease of $17.5 million in revenue relating to our collaboration agreement with Kite, reflecting a reduction in level of our research and development services, and a decrease of $10.3 million in revenue relating to our collaboration agreement with Novartis, due to the impact of termination of the collaboration agreement. These decreases were partially offset by an increase of $2.6 million in revenues from other licensing agreements. Revenues were $176.2 million in 2023, compared to $111.3 million in 2022. The increase of $64.9 million in revenues in 2023 compared to 2022, was primarily attributed to an increase of $106.4 million in revenue relating to our collaboration agreement with Biogen, primarily due to the impact of termination of the collaboration agreement in June 2023, which resulted in an increase in the measure of proportional cumulative performance on this collaboration, an increase of $3.8 million in revenue relating to our license agreement with Sigma-Aldrich Corporation, and an increase of $3.6 million in revenues from other licensing agreements. These increases were partially offset by a decrease of $27.5 million in revenue relating to our collaboration agreement with Novartis due to the termination of the collaboration agreement in June 2023, a decrease of $18.1 million in revenue relating to our collaboration agreement with Kite due to a reduction in the estimated future level of our research and development services related to this collaboration, and a decrease of $3.3 million in revenue relating to our collaboration agreement with Sanofi due to the termination of the collaboration agreement in June 2022. GAAP and Non-GAAP Operating Expenses Three Months Ended Year Ended December 31, December 31, (In millions) 2023 2022 2023 2022 Research and development $ 50.7 $ 66.2 $ 234.0 $ 249.9 General and administrative 13.1 16.4 61.2 62.7 Impairment of goodwill and indefinite-lived intangible assets - - 89.5 - Impairment of long-lived assets 0.3 - 65.5 - Total operating expenses 64.1 82.6 450.2 312.6 Impairment of goodwill and indefinite-lived intangible assets - - (89.5 ) - Impairment of long-lived assets (0.3 ) - (65.5 ) - Depreciation and amortization (1.8 ) (3.3 ) (15.1 ) (12.1 ) Stock-based compensation expense (6.1 ) (8.3 ) (27.4 ) (31.7 ) Non-GAAP operating expenses $ 55.9 $ 71.0 $ 252.7 $ 268.8 Total operating expenses on a GAAP basis for the fourth quarter ended December 31, 2023 were $64.1 million compared to $82.6 million for the same period in 2022. Non-GAAP operating expenses, which exclude impairment charges, depreciation and amortization, and stock-based compensation expense, for the fourth quarter ended December 31, 2023 were $55.9 million, compared to $71.0 million for the same period in 2022. The decrease in total operating expenses on a GAAP and non-GAAP basis was primarily attributable to lower compensation and other personnel costs mainly due to a reduction in the bonus expense and lower headcount as a result of restructuring of operations and a corresponding reduction in workforce announced during the year, and a decrease in research and clinical expenses due to deferral and reprioritization of certain programs. These decreases were partially offset by restructuring charges related to the reductions in workforce announced in April and November 2023, and the France restructuring. The expense related to the France restructuring was recorded in the fourth quarter of 2023 as the payouts are based an ongoing post-employment benefit plan, and the payments were probable and could be estimated as of December 31, 2023. Total operating expenses on a GAAP basis in 2023 were $450.2 million compared to $312.6 million in 2022. Non-GAAP operating expenses, which exclude impairment charges, depreciation and amortization, and stock-based compensation expense, were $252.7 million in 2023 compared to $268.8 million in 2022. Operating expenses on a GAAP basis included non-cash charges relating to impairment of goodwill and indefinite-lived intangible assets of $89.5 million, and impairment of long-lived assets of $65.5 million, which were a result of continued decline in our stock price and related market capitalization and termination of our collaboration agreements with Biogen and Novartis. The decrease in total operating expenses on a non-GAAP basis was primarily attributable to a reduction in the bonus expense and lower headcount as a result of restructurings of operations and corresponding reductions in workforce announced during the year, and a decrease in preclinical and clinical expenses due to the termination of collaboration agreements with Biogen and Novartis and deferral and reprioritization of certain programs. These decreases were partially offset by restructuring charges related to the reductions in workforce announced in April and November 2023, and the France restructuring. Cash, Cash Equivalents and Marketable Securities Cash, cash equivalents and marketable securities as of December 31, 2023 were $81.0 million, compared to $307.5 million as of December 31, 2022. During the year ended December 31, 2023, we raised approximately $15.1 million in net proceeds under our at-the-market offering program. We believe that our available cash, cash equivalents and marketable securities as of December 31, 2023, in combination with potential future cost reductions, will be sufficient to fund our planned operations into the third quarter of 2024, excluding any additional capital raised. We are actively pursuing opportunities to raise additional capital. Financial Guidance for 2024 On a GAAP basis, we expect total operating expenses in the range of approximately $145 million to $165 million in 2024, which includes non-cash stock-based compensation expense and depreciation and amortization, subject to additional funding. We expect non-GAAP total operating expenses, excluding estimated non-cash stock-based compensation expense of approximately $13 million, and depreciation and amortization of approximately $7 million, in the range of approximately $125 million to $145 million in 2024, subject to additional funding.
