Company Overview
About Clasp Therapeutics
Clasp Therapeutics is a clinical-stage immuno-oncology company developing precision T cell engagers (TCEs) that direct the immune system to destroy solid tumors harboring common oncogenic driver mutations. Unlike first-generation TCEs that target proteins shared between tumor and healthy cells, Clasp''s bispecific antibodies recognize tumor-specific peptide-HLA complexes — molecular fingerprints unique to cancer cells created by mutated proteins.
Business Model & Competitive Advantage
The company''s lead program, CLSP-1025, targets the p53R175H mutant peptide presented by HLA-A*02:01, the most prevalent p53 mutation in solid tumors including gastrointestinal, lung, and gynecological cancers. CLSP-1025 is being evaluated in the Phase 1 GUARDIAN-101 dose escalation study, making it the first tumor-specific TCE to enter clinical development. Clasp has also dosed its first patient in this trial.
Competitive Landscape 2025–2026
Clasp''s platform is designed to address the fundamental challenge of solid tumor immunotherapy — achieving tumor-specific cytotoxicity without on-target, off-tumor toxicity to healthy tissue — through its proprietary mutant peptide-HLA targeting approach.
