About
Addition Therapeutics emerged from stealth in December 2025 with $100 million in financing backed by the Gates Foundation, SR One, and Abingworth, developing PRINT — a platform using lipid nanoparticles (LNPs) to deliver RNA and enzyme payloads that integrate therapeutic sequences at specific genomic loci. Unlike traditional AAV gene therapy (which requires viral vectors and can only be dosed once due to immune response), PRINT's non-viral approach is potentially re-dosable, opening gene therapy to chronic diseases beyond rare genetic disorders.
Precision oncology company emerged from stealth Apr 2026 with $100M oversubscribed Series A co-led by RA Capital and a16z Bio; Pointillist platform identifies novel tumor-specific epitopes for antibody-drug conjugates beyond existing ADC targets.
