Expert Systems Celebrates Milestone in Clinical Development of Tivoxavir Marboxil, Potential One-Time Influenza Treatment

Expert Systems, a leader in combining human and artificial intelligence to accelerate drug discovery, celebrates a key milestone in the development of tivoxavir marboxil, a potential best-in-class inhibitor of the highly-conserved influenza protein, CAP-dependent endonuclease (CEN), intended for use across a broad range of flu viruses. Developed by Traws Pharma, Inc. (NASDAQ: TRAW), tivoxavir marboxil (tivoxavir) showed positive topline Phase 1 safety and pharmacokinetic results, supporting its potential as a one-time treatment for influenza.

Expert Systems’ advanced AI-enabled drug discovery platform helped de-risk and fast-track tivoxavir’s development from discovery to the clinic. Topline Phase 1 results demonstrated good overall tolerability and a pharmacokinetic profile that appears to support tivoxavir’s potential use as a one-time treatment for flu, including pandemic flu. The successful outcome of this study positions tivoxavir as a potential best-in-class inhibitor of drug-resistant influenza and bird flu viruses. Phase 2a trials, set to begin in early 2025, will further evaluate tivoxavir’s potential to help alleviate the public health burden associated with flu-related hospitalizations and mortality, especially in older adults and vulnerable populations.

“Tivoxavir’s successful Phase 1 results are a testament to the power of our AI-enabled platform in accelerating the development of cutting-edge therapies,” said Bill Farley, Chief Business Officer at Expert Systems. “Our platform helps de-risks the early stages of drug development, reducing time and costs while ensuring data-driven decisions. We are excited to support Traws Pharma in bringing this innovative flu treatment closer to market.”
