Data show >90% knockdown of TTR following administration in healthy volunteers
Positive safety and tolerability profile for LICA platform-based therapy
Phase 3 program on track to start later this year in patients with all forms of TTR amyloidosis
BOSTON and CARLSBAD, Calif., Sept. 16, 2019 (GLOBE NEWSWIRE) -- Akcea Therapeutics, Inc. (NASDAQ: AKCA), an affiliate of Ionis Pharmaceuticals, Inc., and Ionis Pharmaceuticals, Inc. (NASDAQ: IONS), presented data today from the Phase 1 clinical trial of AKCEA-TTR-LRx in a poster presentation at the Heart Failure Society of America 23rd Annual Scientific Meeting in Philadelphia, Pennsylvania.
AKCEA-TTR-LRx is an antisense drug developed using Ionis’ proprietary LIgand Conjugated Antisense (LICA) technology platform. It was discovered by Ionis and is being co-developed by Ionis and Akcea. AKCEA-TTR-LRx is designed to inhibit the production of transthyretin, or TTR, and is being studied in patients with both the hereditary and the wild type forms of TTR amyloidosis or ATTR.
AKCEA-TTR-LRx Phase 1 Study Results:
The goal of the Phase 1 study was to assess the effects of AKCEA-TTR-LRx on TTR levels in healthy volunteers. In the randomized, double-blind, placebo-controlled, dose-escalation study healthy volunteers were administered AKCEA-TTR-LRx or placebo via a single subcutaneous injection or once every four weeks for 13 weeks followed by an additional 13-week period where patients did not receive treatment. Results from the Phase 1 study show:
Akcea and Ionis also plan to initiate the Phase 3 program for AKCEA-TTR-LRx later this year.
“The Phase 1 data demonstrate an impressive and meaningful reduction in the TTR protein while maintaining a positive safety and tolerability profile with monthly administration of AKCEA-TTR-LRx. These results are encouraging as we expand our commitment to the TTR amyloidosis community through development of AKCEA-TTR-LRx for patients with both hereditary and wild type forms of ATTR amyloidosis,” said Louis O’Dea, chief medical officer at Akcea Therapeutics. “Our goal is to improve patients’ lives with a safe and efficacious therapy that targets and reduces TTR protein at its source. The convenience of monthly administration would also represent a significant advantage for patients living with this debilitating and fatal disease.”
“The significant reductions in TTR levels following treatment combined with a positive safety and tolerability profile further validate the potential of our LICA technology platform to deliver important treatments to patients who are in need of therapeutic options,” said Brett P. Monia, Ph.D., chief operating officer of Ionis Pharmaceuticals. “These data are consistent with the clinical profile seen across our other LICA programs and demonstrate how this advancement in our technology positions us to address more common diseases, including ATTR cardiomyopathy. We look forward to continuing to make important progress in our LICA platform and to advancing the AKCEA-TTR-LRx program through Phase 3.”
AKCEA-TTR-LRx is an antisense drug that uses Ionis’ advanced LIgand Conjugated Antisense, or LICA, technology. It was discovered by Ionis and is being co-developed by Ionis and Akcea. AKCEA-TTR-LRx inhibits the production of the transthyretin (TTR) protein at its source. AKCEA-TTR-LRx is in development to treat a broad population of patients with both hereditary and wild-type forms of transthyretin amyloidosis, or ATTR amyloidosis. AKCEA-TTR-LRx is currently in a Phase 1/2 study with initiation of the Phase 3 program planned for later in 2019.
