- Technology, in-licensed from the Massachusetts Institute of Technology (MIT), capable of inserting DNA sequences of any size into any programmed genomic location
- Potential to create curative cell and integrative gene therapies
- Backed by leading biotech investors Andreessen Horowitz, ARCH, GV, Longwood, Polaris and others
Watertown, MA – Tome Biosciences, Inc., the programmable genomic integration company, has launched to usher in a new era of genomic medicines based on programmable genomic integration (PGI). PGI enables the insertion of any DNA sequence, of any size, into any programmed genomic location. The Company has raised $213 million in Series A and B funding from investors: Andreessen Horowitz (a16z) Bio + Health, ARCH Venture Partners, GV, Longwood Fund, Polaris Partners, Bruker Corporation, FUJIFILM Corporation, Alexandria Venture Investments and others.
“PGI represents the maturation of editing technologies, breaking current barriers in genomic medicines discovery,” said Rahul Kakkar, MD, President and Chief Executive Officer. “PGI is revolutionary in that we can finally reprogram the human genome with an elegance and efficiency previously unimaginable. For patients with rare monogenic diseases, PGI allows for potentially curative treatments with a single drug per disease regardless of genetic heterogeneity, and for patients with more common disorders, PGI allows for the creation of cell therapies at the speed of biologics discovery with a complexity that enables the potential for broad use across human medicine.”
PGI combines the site-specificity of CRISPR/Cas9 with enzymes capable of inserting or writing sequences of DNA, including entire genes, without the need for double-strand DNA breaks. Tome’s most advanced PGI technology, called integrase-mediated PGI (I-PGI), utilizes proprietary integrases and is based on groundbreaking PASTE technology first discovered by Tome’s Co-Founders, Omar Abudayyeh, PhD, and Jonathan Gootenberg, PhD, while at MIT as investigators.
Just as a word processor is capable of pasting text anywhere in a document, I-PGI can insert large DNA sequences anywhere in the genome with unprecedented precision. Thus far, I-PGI has demonstrated insertions of more than 30kb of genetic code with site-specificity in multiple different dividing and non-dividing cell types, and can be multiplexed to enable complex cell engineering that will underpin the future development of cell therapies. Tome has an exclusive license to the core PASTE technology, which includes granted US patent numbers 11,572,556, 11,827,881 and 11,834,658.
“The ability to control where we insert DNA sequences is a game-changer. It means the field can now move away from random integration and utilize any natural promoter in the human genome, enabling us to orchestrate the tissue location, timing and amount of gene expression,” commented John Finn, PhD, Chief Scientific Officer.
The Company initially plans to develop integrative gene therapies for monogenic liver diseases and cell therapies for autoimmune diseases.
Dan Lynch, Chairman of the Board of Directors of Tome and Executive Venture Partner at GV added, “Tome has assembled a truly remarkable team to bring PGI to the many patients who could benefit from this technology. I have seen the incredible progress this team is capable of and look forward to working alongside them as we create new classes of breakthrough cell and integrative gene therapies.”
