About Artios

Artios is on a mission to kill cancer by exploiting DNA damage response (DDR) and repair pathways that are leveraged by cancer cells to promote their survival. Our specialized DcoDeR platform integrates Artios’ leadership capabilities, expertise and experience in DNA damage biology and drug discovery to systematically discover and develop medicines targeting the totality of the DDR. We have built an extensive DDR focused pipeline designed to address areas of high unmet needs across solid tumour indications including our ATR inhibitor, ART0380, and our Polθ inhibitors, ART4215 and ART6043, as monotherapies and with combination treatments. Together with our strategic partnerships with Merck KGaA and Novartis, and research collaborations with premiere institutions like Cancer Research UK, The Institute of Cancer Research, The Netherlands Cancer Institute, and the Crick Institute we are pioneering validated approaches to DDR drug discovery.

About ART0380

ART0380 is a competitive, potentially best-in-class, oral, highly potent, and selective ATR inhibitor. Ataxia telangiectasia and Rad3-related (ATR) is a master regulator of DNA replication stress response that promotes cell death by destabilizing replication forks, inducing DNA damage, or inhibiting checkpoint activation. ART0380 has broad clinical potential and is being investigated alone and in combination with other targeted therapies, chemotherapies and radiosensitiser opportunities in DDR deficient and high replication stress tumors. ART0380 was in-licensed from MDACC and ShangPharma in 2019.

About the DcoDeR platform

Artios has developed a specialized DcoDeR platform which exploits its expertise and experience in DNA damage biology and drug discovery to systematically discover and develop medicines targeting the totality of the DDR. Our world class DNA damage response discovery platform allows us to understand disease biology, identify novel targets, develop new medicines, and select and treat patients who will benefit most. DcoDeR is being leveraged in ongoing research collaborations and licensing agreements with Merck KGaA to identify novel DDR nuclease inhibitors and with Novartis to identify DDR targets to use in combination with radioligand therapies.
