•Completed Enrollment of Phase 1/2 Study Evaluating VAX-31 for the Prevention of IPD in Adults Aged 50 and Older: In January 2024, we announced the completion of enrollment in the Phase 1/2 clinical study evaluating VAX-31 in healthy adults aged 50 and older. This is a randomized, observer-blind, active-controlled, dose-finding study designed to evaluate the safety, tolerability and immunogenicity of VAX-31 at three dose levels (low, middle and high) compared to PCV20 in 1,015 healthy adults aged 50 and older. VAX-31, the broadest-spectrum PCV in the clinic, has the potential to address a significant public health need by covering approximately 95% of IPD circulating in the U.S. adult population while maintaining coverage of previously circulating strains that are currently contained via ongoing vaccination.

Previous report

•Completed Enrollment of Phase 2 Study Evaluating VAX-24 for the Prevention of IPD in Infants: In March 2024, we announced the completion of enrollment in the Phase 2 clinical study evaluating VAX-24 in healthy infants. The Phase 2 clinical study, which enrolled 802 healthy infants, is a randomized, observer-blind, dose-finding two-stage clinical study evaluating the safety, tolerability and immunogenicity of VAX-24 in healthy infants. The Stage 1 portion of the study evaluated the safety and tolerability of a single injection of VAX-24 at three dose levels (low dose/1.1mcg, middle dose/2.2mcg, mixed dose/2.2mcg or 4.4mcg) and compared to PCV15, which was the broadest-spectrum PCV at the time of study initiation, in 48 infants. The Stage 2 portion, which commenced in July 2023, is evaluating the safety, tolerability and immunogenicity of VAX-24 for the prevention of IPD at the same three dose levels and compared to PCV20, currently the broadest-spectrum PCV recommended by the ACIP. Participants who received VAX-24 in Stage 1 will continue the standard dosing regimen as part of Stage 2 and will be included in the safety, tolerability and immunogenicity analysis of the study.

Sutro Biopharma is a clinical stage, publicly traded drug discovery, development and manufacturing company using precise protein engineering and rational design (enabled by Sutro Biopharma’s proprietary XpressCFTM platform technology) to advance next-generation oncology therapeutics. Following our corporate formation, we acquired an exclusive license to Sutro Biopharma’s proprietary cell-free protein synthesis platform, XpressCFTM, for the discovery, development and sale of vaccines for the treatment or prevention of infectious diseases, excluding cancer vaccines. Under a related supply agreement with Sutro Biopharma, we have an exclusive relationship in our field to buy extract and certain custom reagents for use in manufacturing the vaccine compositions covered by the exclusive license, which we use to produce our protein carriers and certain of our antigens. Under a separate agreement with Sutro Biopharma, we enhanced our rights with respect to access to a second supplier of extract and acquired an option to access expanded rights to develop and manufacture extract, among other rights. In November 2023, we exercised this option and entered in a manufacturing rights agreement to obtain control over manufacturing and development of cell-free extract for our vaccine candidates.

•In January 2024, we announced that we received encouraging input from ongoing discussions with the FDA about the VAX-24 adult program to further inform our chemistry, manufacturing and controls (“CMC”) licensure requirements and that we expect to seek additional CMC-focused input from the FDA as we prepare for and potentially conduct our VAX-24 adult Phase 3 program. Following the topline data from the VAX-31 adult Phase 1/2 study, which is expected in the third quarter of 2024, we expect to determine whether to advance VAX-24 or VAX-31 to an adult Phase 3 program. If we move forward with the VAX-24 adult Phase 3 program, we expect to initiate the pivotal, non-inferiority study in adults aged 50 and older in the second half of 2024 and announce topline safety, tolerability and immunogenicity data from this study in the second half of 2025. We would expect to initiate the remaining Phase 3 studies, which are shorter in duration than the non-inferiority study, for VAX-24 in the adult population in 2025 and 2026. If we move forward with the VAX-31 adult Phase 3 program, we expect to initiate the full complement of potential Phase 3 studies in 2025 and 2026. Subject to the results of the adult Phase 3 studies, we would expect to submit a BLA for VAX-24 or VAX-31 shortly following the completion of the last Phase 3 study.

•VAX-GI, a novel preclinical vaccine candidate being developed as a preventative treatment for dysentery and shigellosis, which is caused by Shigella bacteria. Shigella, a bacterial illness that affects an estimated 188 million people worldwide each year and results in approximately 164,000 deaths annually, mostly among children under five years of age in low- and middle-income settings. The central antigen in VAX-GI is IpaB, a well-appreciated antigen that other developers have been unable to produce in an amount sufficient to enable a commercial product. With our cell-free technology, we believe we can produce this antigen at substantially improved yields, allowing for commercial-scale production. VAX-GI is being developed in collaboration with the University of Maryland, Baltimore as well as with partial funding from two research grants awarded by the National Institutes of Health (“NIH”).
