Septerna is a biotechnology company with a vision to become the industry-leading G protein-coupled receptor (GPCR)-focused R&D company with a portfolio of life-changing medicines. The company’s Native Complex™ Platform recapitulates GPCRs with their native structure, function, and dynamics outside of the cellular environment to enable new technologies for industrial-scale drug discovery for the entire GPCR target class for the first time. Septerna has an emerging pipeline of GPCR-targeted small molecule drug discovery programs, along with growth potential to reach many GPCRs that have been undruggable and unexploited to date. Septerna was launched by scientific founders who have made groundbreaking GPCR discoveries and by founding investor Third Rock Ventures. For more information see:
