About AR101 (enzastaurin)
AR101 (enzastaurin) is an orally available investigational first-in-class small molecule, serine/threonine kinase inhibitor of the PKC beta, PI3K and AKT pathways. AR101 has been studied in more than 3,300 patients and over 50 clinical and pharmacological studies across a range of solid and hematological tumor types. Dr. Hal Dietz developed the first preclinical model that mimics the human condition and recapitulates VEDS. This knock-in model has the same genetic mutation most prevalent in VEDS patients and is representative of the human condition in both the timing and location of vascular events. The model has generated identical structural histology and mechanical characteristics, and unbiased findings demonstrated that structure alone does not lead to vascular events. Objective comparative transcriptional profiling by high-throughput RNA sequencing of the aorta displayed a molecular signature for excessive PKC/ERK cell signaling that is the driver of disease. PKC inhibition proved efficacious in multiple pre-clinical models and prevented death due to vascular rupture.
The U.S. Food and Drug Administration (FDA) has granted Orphan Drug designation to AR101 (enzastaurin) for the treatment of Ehlers-Danlos Syndrome. Treatment of vascular Ehlers-Danlos Syndrome (VEDS) is within the scope of this orphan drug designation.
About the PREVEnt Trial
The company expects to initiate the PREVEnt Trial in the first half of 2022 and enroll approximately 260 COL3A1-positive VEDS patients. The study will randomize patients 1:1, with half receiving enzastaurin 500 mg once daily along with standard of care and half receiving placebo once daily along with standard of care. The study’s primary endpoint is reduction in fatal and non-fatal arterial events (ruptures, dissections, pseudo-aneurysms).
About Aytu BioPharma, Inc.
Aytu BioPharma is a specialty pharmaceutical company with a growing commercial portfolio of prescription therapeutics and consumer health products. The company's primary prescription products treat attention deficit hyperactivity disorder (ADHD) and other common pediatric conditions. Aytu markets ADHD products Adzenys XR-ODT® (amphetamine) extended-release orally disintegrating tablets (see Full Prescribing Information, including Boxed WARNING) and Cotempla XR-ODT® (methylphenidate) extended-release orally disintegrating tablets (see Full Prescribing Information, including Boxed WARNING). The company also markets ZolpiMist®, a short-term treatment for insomnia characterized by difficulties with sleep initiation (see Full Prescribing Information, including Boxed WARNING). The company's other pediatric products include Karbinal® ER (carbinoxamine maleate), an extended-release carbinoxamine (antihistamine) suspension indicated to treat numerous allergic conditions, and Poly-Vi-Flor® and Tri-Vi-Flor®, two complementary fluoride-based prescription vitamin product lines containing combinations of fluoride and vitamins in various formulations for infants and children with fluoride deficiency. The company's evolution has been driven by strategic in-licensing, acquisition-based transactions and organic product growth. Aytu is building a complimentary therapeutic development pipeline including a prospective treatment (AR101/enzastaurin) for vascular Ehlers-Danlos Syndrome (VEDS), a rare genetic disease resulting in high morbidity and a significantly shortened lifespan. AR101/enzastaurin has received Orphan Drug designation from the FDA. There are no currently approved treatments for VEDS. To learn more, please visit aytubio.com.
