Plexium is a San Diego precision medicine company designing small-molecule protein degraders - monovalent direct degraders and molecular glues - that switch off disease-driving proteins traditionally considered undruggable. Its DELTA Discovery platform runs ultra-high-throughput cell-based screening to find and optimize new degrader chemistry across cancer and neurological disease.
Arthur T. Sands, M.D., Ph.D., is the President and CEO of Nurix Therapeutics, a clinical-stage biopharmaceutical company pioneering targeted protein degradation medicines. A co-founder of Lexicon Pharmaceuticals in 1995, he spent 19 years transforming that company from a research startup into a drug-development enterprise generating over $450 million in revenue. At Nurix, he leads efforts to deploy a proprietary DEL-AI platform - combining DNA-encoded libraries with machine learning - to discover and develop small-molecule degraders and degrader-antibody conjugates for cancer and inflammatory diseases. The company's lead asset, bexobrutideg (a BTK degrader), entered pivotal Phase 2 development in 2025 with an 83% objective response rate in relapsed CLL patients.
