Scribe Therapeutics vs ImmunoVec
Side-by-side comparison of AI visibility scores, market position, and capabilities
Raised $100M Series B. Jennifer Doudna co-founder. Sanofi + Eli Lilly partnerships. STX-1150 (PCSK9 silencing via CasX-ELXR) IND projected mid-2026 — no permanent DNA edits.
About
Scribe Therapeutics was co-founded by Jennifer Doudna — who shared the 2020 Nobel Prize in Chemistry for CRISPR-Cas9 invention — and develops the ELXR platform: a CasX-based epigenetic silencing system that reduces gene expression without making permanent DNA cuts. The company has raised $100 million in Series B financing with strategic partnerships with Sanofi and Eli Lilly. The lead program, STX-1150, targets PCSK9 for durable LDL-C reduction and is projected to receive an IND and enter human trials in mid-2026.
Received up to $40.7M ARPA-H award (Oct 2025). Polymeric nanoparticle platform to reprogram immune cells in vivo without viral vectors. Non-viral delivery for CAR-T-like therapies.
About
ImmunoVec is developing a non-viral polymeric nanoparticle delivery platform for in vivo immune cell engineering — programming a patient's immune cells directly inside their body without the expensive ex vivo manufacturing process that makes CAR-T therapies cost $500,000-$1,000,000 per treatment. The company received a selective ARPA-H (Advanced Research Projects Agency for Health) award of up to $40.7 million in October 2025 for development of its platform.
