Oscotec & ADEL Begins Trial for ADEL-Y01 in Alzheimer's Disease

Oscotec/ADEL Initiates First-in-Human Dosing in Ph1 of Anti-MTBR Tau Antibody ADEL-Y01 In Alzheimer's Disease

Oscotec Inc. and ADEL Inc. announced the dosing of the first healthy participant in its first-in-human study of ADEL-Y01 for the treatment of Alzheimer's disease (AD).

Oscotec and ADEL are jointly developing a novel disease-modifying immunotherapy agent (ADEL-Y01) targeting tau protein accumulation in the AD brain. ADEL-Y01 is uniquely designed to target tau protein acetylated at lysine-280 (acK280), inhibiting aggregation and propagation of toxic tau and thus may slow the course of the disease.

Phase I Trial

This phase 1a/1b study in the U.S. is to evaluate the safety, tolerability, pharmacokinetics, and clinical activity of ADEL-Y01 in 40 healthy volunteers as well as in 33 participants with Mild Cognitive Impairment due to Alzheimer's disease or mild Alzheimer's disease.

The Target: Tau

"Given that tau is strongly correlated with AD progression and clinical severity, targeting of tau is anticipated to effectively slow the disease progress. As our understanding of the pivotal role of the tau mid-region MTBR increases, selecting the right epitope becomes crucial in developing tau-targeting therapeutics to attain clinical benefits", explained SeungYong Yoon, MD/PhD, CEO of ADEL.

Words from Oscotec

Oscotec is pleased to reach a significant milestone leading the clinical study as a co-developer with ADEL, and we will continue to bring innovative medicines in neurogenerative diseases"", said Taeyoung Yoon, CEO of Oscotec.  

Preclinical Results

• The preclinical results of ADEL-Y01 in animal models were published last year, demonstrating improvement in  memory impairment, behavioral deficits through the inhibition of Tau seeding and propagation.
