SOD1- ALS is a devastating, uniformly fatal, and ultra-rare genetic form of ALS that represents approximately two percent of all ALS cases1 Health Canada regulatory decision on tofersen New Drug Submission expected in early 2025 TORONTO, March 19, 2024 /CNW/ - Biogen Canada Inc. announced today that Health Canada has accepted for review a New Drug Submission(NDS) for tofersen for the treatment of amyotrophic lateral sclerosis (ALS) in adults who have a mutation in the superoxide dismutase 1 (SOD1) gene. If approved, tofersen will be the first treatment indicated in Canada to target a genetic cause of ALS. "The tofersen New Drug Submission represents a critical milestone for the Canadian ALS community and those suffering from this ultra-rare genetic form of the disease that robs them of time with loved ones," said Eric Tse, General Manager of Biogen Canada. "For over a decade, Biogen has been committed to advancing ALS research to provide a deeper understanding of this devastating disease. We are passionate about doing what we can to make a difference and are deeply committed to the rare disease community." According to the ALS Society of Canada, ALS currently impacts an estimated 4,000 Canadians, with approximately 1,000 new Canadians diagnosed each year.2 The NDS is based on results from the Phase 3 VALOR trial, a 28-week randomized, double-blind, placebo-controlled clinical study, which assessed the safety and efficacy of tofersen in patients with weakness attributable to ALS and a confirmed SOD1 mutation. A regulatory decision on the New Drug Submission is expected in early 2025. About tofersen Tofersen is an antisense oligonucleotide (ASO) designed to bind to SOD1 mRNA to reduce SOD1 protein production. The U.S. Food and Drug Administration granted accelerated approval for QALSODY™ (tofersen) to treat amyotrophic lateral sclerosis (ALS) in adults who have a mutation in the superoxide dismutase 1 (SOD1) gene based on reduction in plasma neurofilament light chain (NfL) observed in patients treated with tofersen. Continued approval for this indication may be contingent upon verification of clinical benefit in confirmatory trial(s).3 Tofersen also received a positive opinion from the European Medicines Agency's Committee for Medicinal Products for Human Use (CHMP) recommending its marketing authorization under exceptional circumstances for the treatment of adults with ALS associated with a mutation in the SOD1 gene.4 A decision on a marketing authorization in the European Union is expected in the second quarter of 2024. Biogen licensed tofersen from Ionis Pharmaceuticals, Inc. under a collaborative development and license agreement. Tofersen was discovered by Ionis. In addition to an ongoing open label extension (OLE) of VALOR, tofersen is being studied in the Phase 3, randomized, placebo-controlled ATLAS study to evaluate whether tofersen can delay clinical onset when initiated in presymptomatic individuals with a SOD1 genetic mutation and biomarker evidence of disease activity (elevated plasma NfL). More details about ATLAS (NCT04856982) can be found at clinicaltrials.gov. About Amyotrophic Lateral Sclerosis and SOD1-ALS Amyotrophic lateral sclerosis (ALS) is a rare, progressive, and fatal neurodegenerative disease that results in the loss of motor neurons in the brain and the spinal cord that are responsible for controlling voluntary muscle movement. People with ALS experience muscle weakness and atrophy, causing them to lose independence as they steadily lose the ability to move, speak, eat, and eventually breathe. Average life expectancy for people with ALS is three to five years from time of symptom onset.5 Multiple genes have been implicated in ALS. Genetic testing helps determine if a person's ALS is associated with a genetic mutation, even in individuals without a known family history of the disease. More than 15 percent of people with ALS are thought to have a genetic form of the disease;6 however, they may not have a known family history of the disease.1 SOD1-ALS is diagnosed in approximately two percent of all ALS cases.1 In people with SOD1-ALS, mutations in their SOD1 gene cause their bodies to create a toxic misfolded form of SOD1 protein. This toxic protein causes motor neurons to degenerate, resulting in progressive muscle weakness, loss of function, and eventually, death.6 Biogen's Continuous Commitment to ALS For over a decade, Biogen has been committed to advancing ALS research to provide a deeper understanding of all forms of the disease. The company has continued to invest in and pioneer research despite making the difficult decision to discontinue a late-stage ALS asset in 2013. Biogen has applied important learnings to its portfolio of assets for genetic and other forms of ALS, with the goal of increasing the probability of bringing a potential therapy to patients in need. These applied learnings include evaluating genetically validated targets in defined patient populations, pursuing the most appropriate modality for each target and employing sensitive clinical endpoints. In addition to tofersen, the company has a pipeline of investigational drugs being evaluated in ALS, including BIIB105. About Biogen Founded in 1978, Biogen is a leading biotechnology company that pioneers innovative science to deliver new medicines to transform patient lives and to create value for shareholders and our communities. We apply deep understanding of human biology and leverage different modalities to advance first-in-class treatments or therapies that deliver superior outcomes.

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.
