Vaxcyte completes VAX-31 Phase 3 trial enrollment, shares rise 8.7%

Vaxcyte shares rose 8.7% after completing enrollment for three Phase 3 adult trials of its VAX-31 pneumococcal vaccine candidate and a Phase 2 infant study. The company also announced plans to begin a Phase 1 adult trial for its VAX-A1 Group A Strep programme. The milestone reduces execution risk whilst advancing Vaxcyte's two-pillar strategy targeting both adult and paediatric pneumococcal markets. The company's narrative projects $224.6 million revenue by 2029, representing an earnings increase of approximately $794.7 million from current levels. Some analysts forecast Vaxcyte reaching $424 million revenue by 2029. Key near-term catalysts include OPUS-1 Phase 3 adult data readout, though higher research and manufacturing spending may pressure the company's cash runway before late-stage outcomes are determined.

Vaxcyte to present at the 25th Annual Needham Virtual Healthcare Conference. April 07, 2026 16:05 ET | Source: Vaxcyte, Inc. SAN CARLOS, Calif., April 07, 2026 (GLOBE NEWSWIRE) - Vaxcyte, Inc. (Nasdaq: PCVX), a clinical-stage vaccine innovation company, today announced that Company management will participate in a fireside chat at the 25th Annual Needham Virtual Healthcare Conference on Tuesday, April 14, 2026 at 2:15 p.m. ET / 11:15 a.m. PT. A live webcast of the fireside chat can be accessed through the Investors & Media section of the Company's website at http://investors.vaxcyte.com. A replay of the webcast will be available for approximately 30 days following the conference. About Vaxcyte Vaxcyte is a vaccine innovation company engineering high-fidelity vaccines to protect humankind from the consequences of bacterial diseases. VAX-31, a 31-valent pneumococcal conjugate vaccine (PCV) candidate being evaluated in the OPUS Phase 3 adult clinical program and in a Phase 2 infant clinical program, is being developed for the prevention of invasive pneumococcal disease (IPD) and is the broadest-spectrum PCV candidate in the clinic today. VAX-24, a 24-valent PCV candidate, is designed to cover more serotypes than any infant PCV on-market. VAX-31 and VAX-24 are designed to improve upon standard-of-care PCVs by covering the serotypes in circulation that cause a significant portion of IPD and are associated with high case-fatality rates, antibiotic resistance and meningitis, while maintaining coverage of previously circulating strains. VAX-XL, in earlier-stage development, also leverages the Company's carrier-sparing, site-specific conjugation technology with the aim of further expanding coverage to deliver the broadest-spectrum candidate in the Company's PCV franchise. Vaxcyte is re-engineering the way highly complex vaccines are made through XpressCF(R), its 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 develop 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, and VAX-GI, a vaccine candidate designed to prevent Shigella.

Vaxcyte announces significant development of first-of-its-kind PCV31.

Vaxcyte announces significant development of first-of-its-kind PCV31. With the OPUS-1, 2, and 3 trials underway, Vax-31 has the potential to become the first pneumococcal vaccine of its kind, demonstrating never-before-seen impacts on disease burden. Vaxcyte recently announced significant progress in the clinical development of VAX-31, its 31-valent pneumococcal conjugate vaccine (PCV31) candidate, according to a news release.[1] As the highest-valent PCV currently under development, VAX-31 is being positioned as a potential best-in-class protection against pneumococcal disease for both adults and infants. "The continued advancement of VAX-31 in adults reflects disciplined execution across our phase 3 clinical program, which was finalized in consultation and alignment with the FDA, as we work toward delivering a best-in-class, next-generation PCV with the potential to set a new standard of care for adults and children," Grant Pickering, CEO and co-founder of Vaxcyte, said in the news release. "In adults, evaluating VAX-31 in settings that reflect real-world vaccination practice, including coadministration with a seasonal influenza vaccine and in individuals with prior pneumococcal vaccination, will provide important insights into how VAX-31 is expected to perform across the adult population." Dosing has commenced in the phase 3 OPUS-2 trial, which evaluates the vaccine's performance when administered concomitantly with seasonal influenza vaccines in pneumococcal-naïve adults 50 years and older. Simultaneously, Vaxcyte completed enrollment for a phase 2 infant dose-finding study, marking a critical step toward addressing the leading cause of vaccine-preventable deaths in children under 5 globally.[1] For pharmacists, who serve as the most accessible members of the health care team, these advancements represent a vital expansion of the tools available to combat infectious disease burden, which saw invasive pneumococcal disease (IPD) incidence nearly double between 2012 and 2024.[2,3] The clinical relevance of VAX-31 is underscored by its design to cover approximately 95% of invasive pneumococcal disease (IPD)-causing serotypes circulating in US adults over 50 years.[1] This broad spectrum is necessary because, despite the efficacy of current options like PCV20 and the recently approved PCV21, the phenomenon of serotype replacement continues to push nonvaccine serotypes into prominence.[3] To provide pharmacists and the FDA with real-world data, the OPUS-2 trial utilizes a randomized, double-blind approach to compare concomitant and sequential administration with flu shots, and the upcoming OPUS-3 study will specifically evaluate VAX-31 in adults who have previously received other pneumococcal vaccines, such as the 23-valent pneumococcal polysaccharide vaccine (PPSV23) or PCV20.[1] The push for higher valency, however, brings technical challenges regarding immunogenicity. Research comparing earlier vaccines like PCV7 and PCV13 with newer PCV15 and PCV20 formulations suggested that increasing the number of polysaccharides can sometimes result in lower antibody responses for common serotypes, according to the Canada Communicable Disease Report.[4] To mitigate this, some pipeline candidates - such as Inventprise's PCV25 - are utilizing innovative hydrazide-polyethylene glycol-hydrazide (Hz-PEG-Hz) linker technology to reduce carrier-induced immune interference.[2] Vaxcyte's own platform similarly aims to maintain robust immune responses while expanding coverage, a necessity as the CDC recently lowered the routine vaccination age to 50 years old.[1,5,6] In the pediatric sector, VAX-31 is designed to protect against approximately 92% of IPD serotypes and 96% of acute otitis media cases in children.[1] This is particularly important because PCVs provide nasal immunity by stimulating antibodies in the nasal mucosa, which prevents colonization and is a feature missing from PPSV23.[6] Furthermore, dosing schedules remain a point of clinical discussion, and the World Health Organization supports a 2+1 schedule for healthy children. However, some data indicates that a 3+1 schedule provides superiority.[4] Vaxcyte's ongoing infant study follows the 4-dose series to ensure maximum protection.[1] As the landscape shifts toward sophisticated platforms like Vaxcyte's cell-free protein synthesis system, the goal remains a serotype-independent vaccine - the holy grail of the pneumococcal vaccine industry.[1,7] Pharmacists can bridge current gaps by using the PneumoRecs VaxAdvisor app to navigate complex guidelines and stay updated on Vaxcyte's expanding pipeline, which also includes candidates for Group A Streptococcus and Shigella.[1,2,5] With Vaxcyte committing up to $1 billion toward US manufacturing, the infrastructure is being set to support these next-generation preventions.[1] "We expect to announce topline data from the ongoing OPUS-1 Phase 3 pivotal, noninferiority trial in the fourth quarter of 2026 and results from these additional Phase 3 adult studies in the first half of 2027, keeping us on track toward a planned Biologics License Application submission," concluded Pickering, according to the release.
