We spoke with , CEO and co-founder of Mammoth Biosciences on its CRISPR applications. CRISPR is a technology that permits gene editing by in a cell.

鈥淲e’ve been able to develop proteins to have huge advantages for different therapeutic applications, in particular, in vivo applications, so that you can build permanent genetic cures, rather than just treatments,鈥� said Martin.

In particular, the company is pioneering 鈥渦ltra small CRISPR systems鈥� to build more efficient in vivo therapies.

In vivo therapies are performed inside the body of a living organism.

The company also operates in the new field of CRISPR-based diagnostics. It has built a foundation, in the four years since its founding, of 鈥渢he largest toolbox of CRISPR proteins on earth,鈥� said Martin. Its North Star for diagnostics is 鈥渄emocratizing access to high quality molecular information.鈥�

Amongst its co-founders, the company counts , one of the inventors of CRISPR. Doudna is also the chair of Mammoth’s scientific advisory board.聽

Prior to the pandemic, Mammoth had been interested in leveraging its diagnostics platform for , and 聽 to use its DETECTR聽platform for nucleic acid testing. These tests do not require bulky lab equipment and can produce rapid results at the testing location.聽聽

鈥淥ur diagnostic programs have been accelerated by our work in COVID, but maybe less publicly and just as importantly we’ve really shown that these ultra small systems are incredibly powerful for therapeutic applications. That’s extremely unique and a very exciting area that we’ve unlocked on that side,鈥� said Martin on raising its most recent funding round.
