Syntekabio (KOSDAQ: 226330), an AI and NGS-based drug development company, announced that it has signed multiple co-development agreement on 14th January with Hanmi Science (KOSPI: 008930) to develop COVID-19 treatments utilzing drug repositioning technologies. After signing an MOU with Hanmi Science in September 2020 to develop COVID-19 drug candidates using drug repurposing, Syntekabio has been discussing specific cooperation plans. Through the contract, Syntekabio will also collaborate with Hanmi Science to drive clinical development for its proprietary COVID-19 treatments (Zafirlukast-sulfinpyrazone combination therapy) and subsequent drug repositioning research including clinical development and regulatory affairs. Under the agreement, the two companies aim to discover existing drug candidates’ potential efficacy against COVID-19, and various diseases by utilizing Syntekabio’s proprietary artificial intelligence (AI) drug discovery platform, the Deepmatcher®. In addition, Syntekabio and Hanmi Science work together to develop a digital therapeutics platform for clinical practice. Drug repurposing and indication expansion research data derived from Syntekabio’s proprietary AI-based drug discovery platform will be enlisted on the project. Tyson Kim, the CEO of Syntekabio, said “We expect to accelerate clinical trials and other developments for COVID-19 treatments from the synergy created by collaborating Hanmi Science. We will concentrate our capabilities on both companies to deliver significant outcome.” Jongyoon Lim, the CEO of Hanmi Science, said “Multiple therapeutics and vaccines received emergency use authorization from regulatory agencies, and the in-silico simulation would be an optimal approach for drug repurposing. This would be the first medical contents presented by digital therapeutics of Lightspeed Task Force, initiated by Hanmi Science.” Hanmi Science Lightspeed Task Force to create innovative business models for COVID-19 was launched on January 5. It consists of Hanmi Pharmaceutical Group, Syntekabio, and other biotech companies such as Bioapp, Herings, and EvidNet. The clinical trial design would be responsible for Herings, a digital therapeutics platform company, and the in silico drug repurposing would be responsible for the Syntekabio. ### About Syntekabio, Inc.

Celgene may be busy wrapping up the biggest deal in its existence — the proposed $74 billion sale to Bristol-Myers Squibb — but it’s still snapping up options to nascent immuno-oncology drugs while it can. The latest tie-up involves Kyn Therapeutics, a Boston startup backed by Atlas Venture and OrbiMed to go after metabolites that keep the immune system from attacking cancer. For $80 million upfront and an undisclosed equity investment, Celgene obtains exclusive options to two of these immunometabolism therapies — which they will make a decision about once Kyn is done with the Phase Ib. Both programs have something to do with TDO and IDO, the latter being a pathway Bristol-Myers has gambled $800 million on — only to hastily halt two Phase IIIs in the wake of a rout in the field. But instead of directly and only inhibiting IDO, Kyn has developed drugs to degrade kynurenine or antagonize the aryl hydrocarbon receptor to prevent their binding, which would result in broad suppression of the immune system. The collaboration signals Celgene’s “continued commitment to work with partners,” said Robert Hershberg, head of business development and global alliances. And not just with Kyn, either. Cambridge, MA-based Obsidian Therapeutics says it’s also scored a collaboration with Celgene featuring an exclusive option to in-license its destabilizing domain technology, which it calls an “operating system” for living medicines like CAR-T. It adds that the pact focuses on DD-regulated IL12 and CD40L, but is keeping quiet about the financials. Here’s CEO Michael Gilman on the experience: Needless to say, completing a deal with Celgene in the last couple of weeks has been… interesting. Kudos to their deal team who remained focused and professional despite the turmoil and uncertainty that was undoubtedly swirling around them. And thanks! — Michael Gilman (@michael_gilman) January 18, 2019 Once one of the industry’s most active dealmakers, Celgene has a rep for offering a supportive role for its smaller partners and paying top dollar for its best prospects.
