“Today’s positive CHMP opinion is an important step toward making TEGSEDI available to people with this systemic, progressive and fatal hereditary disease that relentlessly deprives them of their independence and dignity,” said Paula Soteropoulos, chief executive officer at Akcea Therapeutics. “We are now anticipating approval in Europe shortly and we are ready to launch TEGSEDI to bring this new treatment to people with hATTR amyloidosis.”
“For people with hATTR amyloidosis and their families, effective treatment can mean the difference between working or not working, independence or the need for constant care,” said Teresa Coelho, M.D., neurologist and neurophysiologist at Santo António Hospital, Porto, Portugal. “The benefit demonstrated by TEGSEDI in the Phase 3 NEURO-TTR trial on both measures of quality of life and neurological disease progression provides hope for patients and their families that they may be able to maintain greater independence from their disease by alleviating debilitating symptoms while preserving their ability to perform daily activities.”
The positive CHMP opinion for the TEGSEDI Marketing Authorization Application (MAA) is based on results from the Phase 3 NEURO-TTR study and the Open Label Extension study in patients with hATTR amyloidosis with symptoms of polyneuropathy. Results from the NEURO-TTR study demonstrated that patients treated with TEGSEDI experienced significant benefit compared to patients treated with placebo across both co-primary endpoints: the Norfolk Quality of Life Questionnaire-Diabetic Neuropathy (Norfolk QoL-DN) and modified Neuropathy Impairment Score +7 (mNIS+7), a measure of neuropathic disease progression.
Treatment with TEGSEDI was associated with substantial reductions in the levels of the transthyretin (TTR) protein. The abnormal formation and aggregation of TTR protein results in TTR amyloid deposits, which is the underlying cause of hATTR amyloidosis. Risk of thrombocytopenia and glomerulonephritis were identified during the study. Enhanced monitoring was implemented and proven effective during the study to support early detection and management of these issues. The most frequently observed adverse events were associated with injection site reactions.
“This positive CHMP opinion moves Ionis one step closer to becoming a multi-product sustainably profitable company delivering life-changing drugs to patients. Our antisense technology platform continues to deliver many important scientific and medical advances that should support continuing growth,” said Brett P. Monia, Ph.D., chief operating officer at
ABOUT TEGSEDI™ (INOTERSEN)
TEGSEDI™ (inotersen) is an antisense drug designed to reduce the production of transthyretin, or TTR protein, to treat ATTR amyloidosis, a systemic, progressive and fatal disease. TEGSEDI is currently under regulatory review in the US, EU and Canada.
The submission is based on the NEURO-TTR study which was a Phase 3 randomized (2:1), double-blind, placebo-controlled, international study in 172 patients with polyneuropathy due to hATTR amyloidosis. The 15-month study measured the effects of TEGSEDI on neurological dysfunction and on quality-of-life by measuring the change from baseline in the modified Neuropathy Impairment Score +7 (mNIS+7) and in the Norfolk Quality of Life Questionnaire-Diabetic Neuropathy (Norfolk QOL-DN) total score. Risk of thrombocytopenia and glomerulonephritis were identified during the study. Enhanced monitoring was implemented and proven effective during the study to support early detection and management of these issues. The most frequently observed adverse events were associated with injection site reactions.
The NEURO-TTR open label extension (OLE) study is ongoing for patients who completed the NEURO-TTR study. Results from the OLE study have shown that patients treated with TEGSEDI in the NEURO-TTR study who enrolled in the OLE continued to show benefit at the 12-month cut off of the OLE. Furthermore, patients who were treated with placebo in the NEURO-TTR study who enrolled in the OLE also demonstrated evidence of benefit in the OLE at the 12 month cut off of the OLE. No new safety concerns were identified in the OLE. The TEGSEDI expanded access program (EAP) has been initiated for eligible patients in the U.S. Click here for more information on the TEGSEDI EAP.
ABOUT HEREDITARY TRANSTHYRETIN (hATTR) AMYLOIDOSIS￼
hATTR amyloidosis is a progressive, systemic and fatal hereditary disease caused by the inappropriate formation and aggregation of TTR amyloid deposits in various tissues and organs throughout the body, including in peripheral nerves, heart, intestinal tract, eyes, kidneys, central nervous system, thyroid and bone marrow. The progressive accumulation of TTR amyloid deposits in these tissues and organs leads to sensory, motor and autonomic dysfunction often having debilitating effects on multiple aspects of a patient's life. People with hATTR amyloidosis often present with a mixed phenotype and experience overlapping symptoms of polyneuropathy and cardiomyopathy. People with hATTR with symptoms of polyneuropathy are classified into 3 stages: Stage 1 patients do not require assistance with ambulation, Stage 2 patients do require assistance with ambulation and Stage 3 patients are bound to wheelchair.
Ultimately, hATTR amyloidosis results in death within three to fifteen years of symptom onset. Therapeutic options for the treatment of patients with hATTR amyloidosis are limited and there are currently no disease-modifying drugs approved for the disease. There are an estimated 50,000 patients with hATTR amyloidosis worldwide. Additional information on hATTR amyloidosis, including a full list of organizations supporting the hATTR amyloidosis community worldwide, is available at www.hattrchangethecourse.com
