Syntekabio’s repurposed COVID-19 combination therapy shows notable animal efficacy

-      Filed a patent application on the new use of the drugs after in vitro comparative study against Remdesivir in collaboration with a national research institute at ’20 2Q

-      The two drugs, derived from in silico simulation, were administered together to laboratory animals. Results showed the combination therapy demonstrated lung pathogenicity recovery rate of 94.3%, while the Remdesivir showed 44.3%

-      Ongoing negotiation with clinical development and regulatory submission partners for several countries

September 04, 2020 I Syntekabio, an AI and NGS-based drug development company, announced that their COVID-19 combination therapy candidates yielded lung pathogenicity recovery rate of 94.3%, while the Remdesivir showed recovery rate of 44.3%. This animal efficacy study was a collaborative effort with one of the South Korea’s national research institutes.

Early February, the structure of 3CL hydrolase (Mpro) was first published in the Protein Data Bank (PDB)[1]. 3CL hydrolase is an enzyme that plays a key role in gene expression and proliferation of the COVID-19 virus, thereby being an attractive target for development of COVID-19 therapeutics. Based on the structural information of 3CL hydrolase, Syntekabio selected 30 drug candidates by screening more than 3,000 FDA approved drugs, utilizing supercomputer and proprietary AI-based synthetic drug discovery platform. Subsequent in-vitro study narrowed down the initial candidate pool to 3 drugs that exhibited in vitro efficacy to a level comparable to that of the remedesivir. Combination of 2 drugs showed remarkable lung pathogenicity recovery rate compared to those of Remdesivir, on animal models.

These substances have been used for more than 20 years, thus with long-term safety data compared to newer drugs. No serious adverse events were observed on this animal efficacy study.

Regarding this drug re-purposing and research, Sunil Youn, MD, Director of Business Development, said, “The animal efficacy result seems promising, but we need more evidence to be administered to the COVID-19 patients. We are on discussion with prospective partners regarding to the clinical trials, regulatory submission. Sooner or later, we hope to present future development plan and patient access schedule.”
