Clasp Therapeutics is a clinical-stage immuno-oncology company building off-the-shelf, antibody-like T cell engagers that target cancer driver mutations presented on tumor cells via HLA. Spun out of Johns Hopkins and co-founded by cancer-genetics pioneer Bert Vogelstein and immunotherapy leader Drew Pardoll, Clasp uses its proprietary pHLAre platform to redirect a patient's own T cells to kill tumors with what the company calls absolute specificity - hitting mutant peptides found only on cancer cells while sparing healthy tissue. The company launched publicly in March 2024 with a $150 million Series A and dosed its first patient in April 2025.
Jung Choi is the President and CEO of Alterome Therapeutics, a clinical-stage precision oncology company pioneering mutation-specific cancer drugs. With over 20 years in biopharmaceutical leadership - spanning Gilead Sciences, InterMune, Chimerix, and Global Blood Therapeutics where he led a $5.4B Pfizer acquisition - Choi brought deal-making, strategy, and operational depth to Alterome when he was appointed CEO in April 2025. Under his leadership, Alterome has advanced two first-in-class inhibitors into Phase 1/1b trials targeting KRAS and AKT1 E17K oncogenic drivers, backed by $231M in total funding including a $132M Series B.
