SEONGNAM-SI, South Korea--(BUSINESS WIRE)--AriBio Co., Ltd. (AriBio) receives Notice of Acceptance for POLARIS-AD, a Phase 3 early Alzheimer’s disease clinical trial from the Medicines and Healthcare Products Regulatory Agency (MHRA) in the United Kingdom (UK). The MHRA completed their review on the 21 of February and confirmed a favorable ethical opinion, the Company expects to initiate the clinical trial before the end of Q1’2024 in the UK.

POLARIS-AD is a double-blind, randomized, placebo-controlled, multi-center registration trial to evaluate the efficacy and safety of AR1001 (Mirodenafil) over 52 weeks of treatment in patients with early Alzheimer’s disease. The trial is using the U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA) accepted primary endpoint, Clinical Dementia Rating Scale–Sum of Boxes (CDR-SB), as well as secondary endpoints including Alzheimer’s Disease Assessment Scale-Cognitive Subscale 13 (ADAS-Cog 13), Amsterdam-Instrumental Activities of Daily Living Questionnaire (A-iADL), Geriatric Depression Scale (GDS), Mini-Mental Status Examination (MMSE), in addition to changes in cerebral spinal fluid (CSF) and plasma biomarkers. All early Alzheimer’s disease participants enrolled and will have confirmation of amyloid.

“Acceptance of the POLARIS-AD clinical study in the UK is another achievement in the development of AR1001. This acceptance represents the third region that will be actively screening and enrolling participants in Q1’2024. As stated previously, AriBio will continue to expand the study into other regions where the regulatory and commercial markets are favorable for novel Alzheimer’s disease treatments,” stated James Rock, AriBio Chief Clinical Officer.

Pre-clinical studies have confirmed neuroprotective effects of AR1001 via inhibiting neuron apoptosis and restoring synaptic plasticity demonstrating multiple mechanisms of action that may ameliorate the course of AD.
