SR One in the News 

SR One Capital Management has recently made headlines for many big steps and investments. Here, you can get a picture of its recent moves in raising funds for its companies and its own growth.

  • In April 2021, Pandion Therapeutics—an SR One portfolio company—that develops modular antibodies and proteins to treat inflammatory and autoimmune disorders, was acquired by Merck at a purchase price of $60 per share. Now, Pandion is a completely owned subsidiary of Merck.
  • Design Therapeutics closed its initial public offering at approximately $276 million—a gross amount, without deduction of any commission, underwriting discounts, and offering expenses. They were funded by SR One.


Design Therapeutics is a biotechnology company designing and developing a gene-targeted chimera platform to treat severe degenerative disorders.

  • The company expanded its expert team by adding two venture partners: Chris Chai and Peter Van Vlasselaer, Ph.D. They both have strong backgrounds in the formation and development of early-stage biotech companies, with a focus on fundraising, drug development, and operations.
  • In November 2020, SR One raised $500 million, the first independent fund, after completing its spinout from GSK. This has been the biggest move for the company. Through this fundraising, it has established itself as an independent fund management business. The company will use the funds to build transformative life sciences companies that will address the issue of unmet demands in medical and clinical fields.
