Ionis announces European Medicines Agency accepts Marketing Authorization Application of tofersen to treat rare, genetic form of ALS
On December 5, 2022, Ionis Pharmaceuticals announced the acceptance of its marketing authorization application (MAA) for tofersen by the European Medicines Agency (EMA) to treat SOD1-ALS. This follows the FDA's acceptance earlier in 2022, with a PDUFA date set for April 25, 2023. If approved, tofersen will be the first therapy targeting a genetic cause of ALS, which affects around 2% of ALS patients globally. The MAA includes data from several studies, and Biogen will maintain its early access program for tofersen across 34 countries.
- EMA acceptance of tofersen's MAA signifies progress in ALS treatment, potentially leading to the first drug targeting a genetic cause of the disease.
- Positive results from the Phase 3 VALOR study included in the MAA.
- None.
- SOD1-ALS affects approximately
2% of people living with ALS worldwide1 - If approved, tofersen would be the world's first treatment to target a genetic cause of ALS
- EMA acceptance follows FDA's acceptance of tofersen NDA earlier this year
CARLSBAD, Calif., Dec. 5, 2022 /PRNewswire/ -- Ionis Pharmaceuticals, Inc. (Nasdaq: IONS) today announced that the European Medicines Agency (EMA) has accepted the marketing authorization application (MAA) for review of tofersen, an investigational medicine for the treatment of superoxide dismutase 1 (SOD1) amyotrophic lateral sclerosis (ALS). SOD1-ALS is a progressive and uniformly fatal disease that affects fewer than 1,000 people across Europe.2
The EMA is the second regulatory agency to accept review of a marketing application for tofersen following U.S. Food and Drug Administration (FDA) acceptance earlier this year. The FDA has set a PDUFA date for tofersen of April 25, 2023. There are currently no treatments targeted for SOD1-ALS.
"EMA acceptance of the tofersen MAA is a significant development for people and families battling SOD1-ALS," said C. Frank Bennett, Ph.D., executive vice president, chief scientific officer and franchise leader for neurological programs at Ionis. "If approved, tofersen will be the world's first treatment that targets a genetic cause of ALS. Tofersen also strengthens Ionis' platform strategy to target other neurological diseases, including other forms of ALS."
The MAA includes results from the Phase 3 VALOR study, its open label extension (OLE) study, a Phase 1 study in healthy volunteers and a Phase 1/2 study evaluating ascending dose levels. Also included are the most current 12-month integrated results from VALOR and the OLE study that were recently published in The New England Journal of Medicine.
Biogen announced that it will maintain its early access program for tofersen, which is now available in 34 countries. Biogen also announced that it will continue to actively engage with other regulators around the world and will provide updates when appropriate.
Tofersen is an antisense medicine being evaluated for the potential treatment of SOD1-ALS. Tofersen binds to SOD1 mRNA, allowing for its degradation by RNase-H in an effort to reduce synthesis of SOD1 protein production. In addition to the ongoing open label extension of VALOR, tofersen is being studied in the Phase 3 ATLAS study designed to evaluate whether tofersen can delay clinical onset when initiated in presymptomatic individuals with a SOD1 genetic mutation and biomarker evidence of disease activity. Biogen licensed tofersen from Ionis under a collaborative development and license agreement.
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. Patients with some SOD1 mutations have an even shorter life expectancy.
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 family history of the disease. Currently, there are no genetically targeted treatment options for ALS. Mutations in the SOD1 gene are responsible for approximately
