OTTAWA, May 13, 2020 /CNW/ - Akcea Therapeutics Canada, Inc., a subsidiary of Akcea Therapeutics, Inc. (NASDAQ: AKCA), today announced that it has concluded its negotiation with the pan-Canadian Pharmaceutical Alliance (pCPA) with a Letter of Intent regarding TEGSEDI™ (inoterson) for the treatment of stage 1 or stage 2 polyneuropathy in adult patients with hereditary transthyretin amyloidosis (hATTR)¹. Akcea Therapeutics, Inc. is a majority-owned affiliate of Ionis Pharmaceuticals, Inc.

"We're very pleased to have achieved this important milestone in our efforts to secure coverage of TEGSEDI for those living with the polyneuropathy of hATTR in Canada," said Jared Rhines, senior vice president, Americas, and general manager at Akcea Therapeutics Canada. "This achievement underscores the data supporting TEGSEDI and the critical unmet need for these patients living with this progressive disease. We appreciate the pCPA team's thorough review and response, which lays the path forward for our discussions with the provinces, territories and federal agencies. We understand that these are challenging times with COVID-19 and we look forward to productive discussions at the earliest, appropriate, time." 

Approved in October 2018, following a priority review by Health Canada, TEGSEDI is an RNA-targeted therapeutic and was the first treatment approved for Canadians living with hATTR, which is caused by the inappropriate formation and aggregation of TTR amyloid deposits in various tissues and organs throughout the body. 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.^2,3,4

hATTR amyloidosis is an under-recognized, debilitating and progressive disease that is caused by the buildup of TTR proteins that misfold due to inherited mutations. It is characterized by the deposition of amyloid fibrils throughout the body including in nervous tissue and can have a devastating impact on patients' quality of life. TEGSEDI is a once-weekly, at-home subcutaneous injection that targets the polyneuropathy of hATTR amyloidosis at its source by reducing production of the TTR protein. 

Special Warnings and Precautions
TEGSEDI is associated with reductions in platelet count, which may result in thrombocytopenia. Platelet count should be monitored at least every 2 weeks during treatment with TEGSEDI and for 8 weeks following discontinuation of treatment. Glomerulonephritis has occurred in patients treated with TEGSEDI. Careful monitoring of UPCR and eGFR is important during treatment with TEGSEDI. The most common adverse reactions that occurred in at least 20% of TEGSEDI-treated patients and that occurred more frequently than on placebo were injection site erythema, nausea, fatigue, diarrhea, headache and injection site pain.
