SAN CARLOS, Calif. and SOUTH SAN FRANCISCO, Calif., Nov. 27, 2023 (GLOBE NEWSWIRE) -- Vaxcyte, Inc. (Vaxcyte) (NASDAQ: PCVX) and Sutro Biopharma, Inc. (Sutro) (NASDAQ: STRO) today announced that Vaxcyte has exercised its option and entered into a manufacturing rights agreement with Sutro to obtain control over the development and manufacture of cell-free extract, a key component of Vaxcyte’s pneumococcal conjugate vaccine (PCV) franchise, which includes VAX-24 and VAX-31. Pursuant to the manufacturing rights agreement, Vaxcyte obtained exclusive rights to independently, or through certain third parties, develop, improve and manufacture cell-free extract for use in connection with the Company’s vaccine candidates.
“As we advance our lead PCV candidate, VAX-24, into late-stage clinical development, exercising the option to establish a manufacturing rights agreement with Sutro enables us to have full control over the development and manufacturing of cell-free extract for our vaccine candidates,” said Grant Pickering, Chief Executive Officer and Co-founder of Vaxcyte. “This is another important step in Vaxcyte’s long-term commercial manufacturing strategy to support the potential global commercialization of our PCV candidates, VAX-24 and VAX-31, for both adult and pediatric populations.”
“Sutro is pleased to support Vaxcyte as an independent developer and manufacturer of cell-free extract for its vaccine candidates, including its PCV franchise, and we look forward to continuing the decade-long relationship between our companies,” said Bill Newell, Chief Executive Officer of Sutro. “Over the past year, Vaxcyte has made significant progress with its VAX-24 clinical program, reporting positive results for two Phase 2 studies in adults. The XpressCF® cell-free protein synthesis platform and cell-free extract are essential in the development of Vaxcyte’s vaccine candidates, which further highlights the value of our platform capabilities.”
Upon exercising the option, which was granted pursuant to the December 2022 option grant agreement between the parties, Vaxcyte paid Sutro $50 million in cash and is obligated to pay Sutro an additional $25 million in cash within six months. Upon the occurrence of certain regulatory milestones, Vaxcyte would be obligated to pay Sutro certain additional milestone payments totaling up to $60 million in cash.
Vaxcyte is a vaccine innovation company engineering high-fidelity vaccines to protect humankind from the consequences of bacterial diseases. The Company is developing broad-spectrum conjugate and novel protein vaccines to prevent or treat bacterial infectious diseases. Vaxcyte’s lead candidate, VAX-24, is a 24-valent, broad-spectrum, carrier-sparing PCV being developed for the prevention of invasive pneumococcal disease and is poised to move into late-stage development. VAX-31, the Company’s next-generation, 31-valent PCV candidate, is the broadest-spectrum PCV in the clinic today.
Vaxcyte is re-engineering the way highly complex vaccines are made through modern synthetic techniques, including advanced chemistry and the XpressCF™ cell-free protein synthesis platform, exclusively licensed from Sutro Biopharma, Inc. Unlike conventional cell-based approaches, the Company’s system for producing difficult-to-make proteins and antigens is intended to accelerate its ability to efficiently create and deliver high-fidelity vaccines with enhanced immunological benefits. Vaxcyte’s pipeline also includes VAX-A1, a prophylactic vaccine candidate designed to prevent Group A Strep infections; VAX-PG, a therapeutic vaccine candidate designed to slow or stop the progression of periodontal disease; and VAX-GI, a vaccine program designed to prevent Shigella. Vaxcyte is driven to eradicate or treat invasive bacterial infections, which have serious and costly health consequences when left unchecked.
