Ionis' Factor XI anti-thrombotic medicine advances with Bayer following positive clinical results
- IONIS-FXI-LRx Ionis' first-in-class FXI anti-thromboticmedicine, to potentially treat millions of patients globally
IONIS-FXI-LRx utilizes Ionis' advanced LIgand Conjugated Antisense (LICA) technology platform and is designed to reduce the production of Factor XI (FXI), a clotting factor produced in the liver. High levels of FXI increase the risk of thrombosis and can be responsible for heart attacks and strokes. Alternatively, individuals deficient in FXI have a lower incidence of thrombosis-related events and little to no increase in bleeding risk.
"Ionis was first to validate Factor XI and the intrinsic coagulation pathway as a novel antithrombotic strategy. Our antisense medicine targeting Factor XI demonstrates potent antithrombotic activity with little to no bleeding in multiple patient populations. This enables, for the first time, the potential to separate anti-thrombotic activity from bleeding risk," said
"Bayer and Ionis have a common vision of bringing innovative therapies to patients," said Dr.
Review of the full data package by Ionis and Bayer is ongoing, and the positive clinical results will be presented at an upcoming medical congress.
IONIS-FXI-LRx is a Generation 2+ ligand-conjugated antisense (LICA) drug designed to reduce the production of Factor XI, a clotting factor produced in the liver that is an important component of the coagulation pathway. High levels of Factor XI increase the risk of blood clot formation inside blood vessels (thrombosis), which can cause heart attacks and strokes. Alternatively, individuals deficient in Factor XI have a lower incidence of thrombosis-related events and little to no increase in bleeding risk. This makes Factor XI an attractive target for an antithrombotic drug because of the potential to separate antithrombotic activity from bleeding risk. Although currently available anticoagulants reduce the risk of thrombosis, these anticoagulants are associated with increased bleeding risk at therapeutic doses, which can lead to major, sometimes fatal bleeding events. In clinical studies evaluating the safety and efficacy of the non-LICA version of IONIS-FXI-LRx (IONIS-FXIRx), dose-dependent inhibition of Factor XI activity was demonstrated, which was associated with significant reductions in clotting events and no increase in major bleeding events. These data coupled with data in humans with little to no Factor XI activity provide evidence that IONIS-FXI-LRx has the potential to be used broadly as an anti-thrombotic in different therapeutic settings for which additional safe and well tolerated anti-thrombotic drugs are needed, especially in patient populations that are at high risk for thrombosis and are also at high risk for bleeding.
As the leader in RNA-targeted drug discovery and development, Ionis has created an efficient, broadly applicable, drug discovery platform called antisense technology that can treat diseases where no other therapeutic approaches have proven effective. Our drug discovery platform has served as a springboard for actionable promise and realized hope for patients with unmet needs. We created the first and only approved treatment for both children and adults with spinal muscular atrophy as well as the world's first RNA-targeted therapeutic approved for the treatment of polyneuropathy in adults with hereditary transthyretin amyloidosis. Our sights are set on all the patients we have yet to reach with a pipeline of more than 40 novel medicines designed to treat a broad range of diseases including cardiovascular diseases, neurological diseases, infectious diseases, pulmonary diseases and cancer.
