Problem
Current gene editing technologies often lack the precision and efficiency needed to correct the genetic causes of severe diseases, particularly when large DNA edits are required. Existing methods can introduce unintended mutations or fail to achieve the desired therapeutic outcome due to limitations in targeting and enzymatic activity.
Solution
Seamless Therapeutics is developing a gene editing platform based on programmable recombinases, a class of enzymes capable of making large, precise DNA deletions or insertions anywhere in the genome. The company's technology reprograms recombinases to target specific DNA sequences, enabling efficient and accurate gene editing without introducing additional mutations. This approach aims to address the underlying genetic causes of severe diseases by precisely correcting faulty genes and restoring normal cellular function. Seamless Therapeutics is developing a pipeline of disease-modifying product candidates across a broad spectrum of indications to expand the therapeutic potential of gene editing.
Target Audience
The primary target audience includes pharmaceutical companies and research institutions focused on developing gene therapies for severe genetic diseases.
