BASEL, Switzerland and Cambridge, Massachusetts – CRISPR Therapeutics, a biopharmaceutical company focused on translating CRISPR/Cas9 gene-editing technology into transformative medicines, today announced an additional $38 million closing of its Series B financing. This additional investment brings the total Series B financing round to nearly $140 million.

"Along with the recent investments made by our strategic partners, Vertex and Bayer, we believe this further investment represents a strong validation of our approach to translate the novel CRISPR/Cas9 gene-editing technology into life-changing medicines for patients. We plan to use these proceeds to advance our current and future programs to the clinic and to expand our research and development organization in Cambridge, Massachusetts."
