Sutro continues to seek to maximize the value of its proprietary cell-free platform by working with partners on programs in multiple disease spaces and geographies and has generated from collaborators an aggregate of approximately $854 million in payments through December 31, 2023, including equity investments.

In November 2023, Vaxcyte exercised its option to enter into a manufacturing rights agreement with Sutro to obtain control over the development and manufacture of cell-free extract for use under its license agreement with Sutro, including for Vaxcyte’s pneumococcal conjugate vaccine (PCV) franchise, which includes VAX-24 and VAX-31. Upon exercising the option, Vaxcyte paid Sutro $50 million and is obligated to pay Sutro an additional $25 million within six months. Upon the occurrence of certain regulatory milestones, Vaxcyte would be obligated to pay Sutro up to an additional $60 million.
