Company Overview

About Addition Therapeutics

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.

Business Model & Competitive Advantage

The Gates Foundation's cornerstone role is the most significant signal: the foundation does not invest in biotechnology for financial returns — it invests in technologies with potential to address health challenges at global scale, particularly in low- and middle-income countries. A $100 million backing from Gates at stealth exit validates that PRINT's platform has credibility beyond rare Western diseases, likely targeting conditions like infectious disease, anemia, or metabolic disorders where gene therapy could have massive population-level impact.

Competitive Landscape 2025–2026

The re-dosable nature of PRINT is its core clinical advantage: all existing AAV gene therapies are one-time treatments because the immune system mounts an antibody response that prevents re-dosing. PRINT's LNP delivery avoids viral capsid immunogenicity, theoretically enabling booster dosing as needed — a critical advantage for diseases where a single gene therapy dose may not provide lifetime correction.
