Vaxcyte Doses First Participant In Phase 1 Study Evaluating VAX-A1 For The Prevention Of Disease Caused By Group A Streptococcus In Healthy Adults

Vaxcyte, Inc. announced that the first participant was dosed in the Phase 1, first-in-human study evaluating VAX-A1, the Company’s investigational prophylactic vaccine candidate for the prevention of disease caused by Group A Streptococcus (Group A Strep), in healthy adults aged 18 to 40 years. The Company expects to announce topline data from the study in the second half of 2027. The primary objective of this randomized, double-blind, placebo-controlled, dose-escalation, two-stage study is assessing the safety and tolerability of VAX-A1, along with a secondary objective of evaluating initial immunogenicity data, to support potential further advancement. The Stage 1 portion of the study is evaluating three dose levels (Low, Mid and High) compared to placebo in approximately 12 adults in a controlled, staged enrollment and dose-escalation approach. Following completion of the Stage 1 Month 1 visit, an independent Data Safety Monitoring Board (DSMB) will review unblinded safety and tolerability data. Upon DSMB approval, the Stage 2 portion of the study is expected to proceed and evaluate the same three dose levels compared to placebo in approximately 68 adults. All participants in the study will be evaluated for safety through six months following the second dose. Group A Strep is responsible for approximately 800 million new cases of illness and more than 600,000 deaths annually worldwide, with no approved vaccine and significant public health burden. About the VAX-A1 Adult Phase 1 Study: This randomized, double-blind, placebo-controlled, two-stage, dose-escalation clinical study is evaluating VAX-A1 in approximately 80 healthy adults aged 18 to 40 years. Stage 1 of the study will enroll approximately 12 participants to evaluate VAX-A1 at three dose levels (Low, Mid and High), in a controlled, staged enrollment and dose-escalation approach. Dose escalation for each cohort in Stage 1 will be based on a review of blinded safety and tolerability data by the Company’s Internal Safety Team prior to proceeding with enrolling the next cohort. Following completion of the Stage 1 Month 1 visit, an independent DSMB will review unblinded safety and tolerability data. Upon DSMB approval, Stage 2 is expected to proceed and enroll approximately 68 participants to further evaluate VAX-A1 across the same three dose levels. The study is being conducted at an investigative site in Australia, where Group A Strep has been especially problematic and where there are experienced investigator networks with expertise in Group A Strep. Participant Overview: Stage 1 (n=12): Participants will be randomized 3:1 to receive VAX-A1 or placebo across three dose levels (Low, Mid and High). Stage 2 (n=68): Participants will be randomized 1:1:1:1 to receive VAX-A1 at one of the three dose levels or placebo. All participants are expected to receive two doses administered approximately two months apart. Safety and Immunogenicity Assessments: Primary objectives include evaluation of safety and tolerability, including assessment of solicited and unsolicited adverse events, serious adverse events and adverse events of special interest. Secondary objectives include evaluation of antigen-specific immune responses to Group A Strep antigens, including serum immunoglobulin G (IgG) responses to C5a peptidase (ScpA), streptolysin O (SLO), S. pyogenes adhesion and division protein (SpyAD) and a universal polysaccharide (modified Group A carbohydrate or GACPR). Safety and tolerability will be assessed for approximately six months following the second and final vaccination. About Group A Strep: Group A Strep is one of the leading causes of bacterial infections worldwide, responsible for a broad spectrum of disease ranging from common illnesses such as strep throat and skin infections to severe invasive disease, including necrotizing fasciitis and streptococcal toxic shock syndrome, as well as immune-mediated sequelae such as acute rheumatic fever, rheumatic heart disease and post-streptococcal glomerulonephritis, a form of kidney inflammation. With an estimated 800 million new cases of illness and more than 600,000 deaths annually worldwide, Group A Strep remains a major clinical burden. The economic impact is substantial, exceeding an estimated $6 billion annually in the U.S. alone. The public health challenge associated with Group A Strep is compounded by evolving epidemiology, including increasing rates of invasive disease and the re-emergence of certain manifestations in markets with historically lower disease burden. Group A Strep also drives significant antibiotic use, especially among children, contributing to rising resistance to multiple antibiotic classes. As a result, Group A Strep contributes to the global threat of antimicrobial resistance (AMR), reinforcing the need for preventative approaches such as vaccination. About VAX-A1: VAX-A1 is a prophylactic vaccine candidate designed to provide broad protection against Group A Strep by targeting conserved antigens associated with immune evasion and virulence. The candidate incorporates three protein antigens, including C5a peptidase (ScpA), streptolysin O (SLO) and S. pyogenes adhesion and division protein (SpyAD), as well as a modified Group A carbohydrate (GACPR) designed to remove potentially cross-reactive epitopes historically associated with autoimmune complications. VAX-A1 is being developed using Vaxcyte’s cell-free protein synthesis platform, which enables precise antigen design and site-specific conjugation intended to preserve immunogenicity while avoiding problematic regions. The vaccine is designed to induce functional immune responses against conserved structures of the pathogen and disarm its defense mechanisms, providing broad, strain-independent protection. This approach is intended to address limitations of prior vaccine strategies, including antigen variability and concerns regarding autoimmune cross-reactivity.

Vaxcyte Inc Completes Enrollment Of OPUS-1 And OPUS-2 Phase 3 Trials Evaluating VAX-31 For The Prevention Of Invasive Pneumococcal Disease And Pneumonia In Adults

Vaxcyte, Inc. announced the completion of enrollment in the VAX-31 OPUS-1 Phase 3 pivotal, noninferiority trial with approximately 4,000 participants and the OPUS-2 Phase 3 trial evaluating VAX-31 concomitantly administered with a seasonal influenza vaccine in approximately 1,300 participants. The Phase 3 program evaluating VAX-31, the Company’s next-generation 31-valent pneumococcal conjugate vaccine (PCV) candidate, for the prevention of invasive pneumococcal disease (IPD) and pneumonia in adults was finalized in consultation and alignment with the U.S. Food and Drug Administration (FDA) and is intended to generate a broad and robust dataset to support a planned Biologics License Application (BLA) submission. Topline safety, tolerability and immunogenicity data from OPUS-1 Phase 3 study are expected in Fourth Quarter of 2026. Results from the OPUS-2 and OPUS-3 trials are expected in the first half of 2027. The pivotal Phase 3 study of VAX-31 is now fully enrolled with approximately 4,000 adults. The randomized, double-blind, active-controlled trial is evaluating the safety, tolerability and immunogenicity of the VAX-31 High Dose, the adult formulation being evaluated in the OPUS Phase 3 program, in healthy, pneumococcal-naïve U.S. adults aged 50 years and older, with a separate cohort of adults aged 18-49 years. In this formulation, all serotypes are dosed at 3.3 mcg, except serotypes 1, 5 and 22F, which are dosed at 4.4 mcg. The study is being conducted at approximately 50 sites across the United States. Adults aged =50 years: Participants in this age group were randomized 1:1:1 to receive a single dose of VAX-31, Capvaxive (PCV21) or Prevnar 20 (PCV20) on Day 1. Adults aged 18-49 years: Participants in this age group were randomized 3:1 to receive a single dose of VAX-31 or PCV20 on Day 1, with PCV20 serving as the safety comparator. For all participants, safety and tolerability will be assessed for six months following initial vaccination of VAX-31, PCV21 or PCV20. Primary immunogenicity objectives: Noninferiority of VAX-31 compared with PCV21 and/or PCV20 for the 28 serotypes shared with either or both comparator vaccines in adults aged 50 years and older (criterion: lower bound (LB) of the two-sided 95% confidence interval (CI) of the OPA GMR is >0.667). Superiority of VAX-31 compared with PCV21 or PCV20 for the three serotypes unique to VAX-31 (2, 7C and 20C) and for serotype 20B in adults aged 50 years and older (criterion: LB of the two-sided 95% CI of the OPA GMR is >2.0). Noninferiority of VAX-31 immune responses in adults aged 18-49 years compared with those in adults aged 50-64 years (criterion: LB of the two-sided 95% CI of the OPA GMR is >0.667). Key secondary immunogenicity objectives: Noninferiority of VAX-31 compared with both PCV21 and PCV20 for the 11 serotypes common to all three vaccines in adults aged 50 years and older (criterion: LB of the two-sided 95% CI of the OPA GMR is >0.5). Statistically greater immune responses elicited by VAX-31 compared with those elicited by PCV21 or PCV20 for the 28 shared serotypes in adults aged 50 years and older (criterion: LB of the two-sided 95% CI of the OPA GMR is >1.0). Superiority of VAX-31 compared with PCV20 for the eight serotypes common to VAX-31 and PCV21 but not included in PCV20 in adults aged 50 years and older (criterion: LB of the two-sided 95% CI of the OPA GMR is >2.0). Superiority of VAX-31 compared with PCV21 for the nine serotypes common to VAX-31 and PCV20 but not included in PCV21 in adults aged 50 years and older (criterion: LB of the two-sided 95% CI of the OPA GMR is >2.0). VAX-31 serotypes (31): 1, 2, 3, 4, 5, 6A, 6B, 7C, 7F, 8, 9N, 9V, 10A, 11A, 12F, 14, 15A, 15B, 16F, 17F, 18C, 19A, 19F, 20C, 22F, 23A, 23B, 23F, 31, 33F, 35B. Serotypes common to VAX-31, PCV21 and PCV20 (11): 3, 6A, 7F, 8, 10A, 11A, 12F, 15B, 19A, 22F, 33F. Serotypes common to VAX-31 and PCV20 but not in PCV21 (9): 1, 4, 5, 6B, 9V, 14, 18C, 19F, 23F. Serotypes common to VAX-31 and PCV21 but not in PCV20 (8): 9N, 15A, 16F, 17F, 23A, 23B, 31, 35B. Serotypes unique to VAX-31 (3): 2, 7C, 20C (20B is also being evaluated). OPUS-2 Phase 3 study, which is now fully enrolled with approximately 1,300 adults, is a randomized, double-blind, placebo-controlled clinical trial designed to evaluate the safety, tolerability and immunogenicity of VAX-31 when administered either concomitantly with or one month following administration of a licensed seasonal influenza vaccine in pneumococcal-naïve, healthy U.S. adults aged 50 years and older. The results of this descriptive study are intended to inform the design of a potential post-licensure outcomes study that further evaluates VAX-31 in concomitant use with an influenza vaccine and to provide supportive evidence as part of the broader Phase 3 dataset. The study is being conducted at approximately 25 sites in the United States. Participants were randomized 1:1 into one of two groups: Concomitant Administration Group: Participants received a seasonal influenza vaccine administered open-label and concomitantly with VAX-31 administered blinded on Day 1, followed by a blinded placebo injection at Month 1. Sequential Administration Group: Participants received a seasonal influenza vaccine administered open-label with a blinded placebo injection on Day 1, followed by VAX-31 administered blinded at Month 1. This sequential dosing approach allows for evaluation of immune responses to VAX-31 when administered alone, while preserving blinding and controlling for vaccination timing. For all participants, safety and tolerability will be assessed for six months following initial vaccination. Primary immunogenicity objectives: Assessing serotype-specific immune responses (opsonophagocytic activity (OPA) geometric mean titers (GMTs) and geometric mean fold rises (GMFRs)) elicited by VAX-31 across all 31 serotypes and serotype 20B in pneumococcal-naïve adults aged 50 years and older. Comparing strain-specific immune responses (hemagglutination inhibition (HAI) GMTs) elicited by a seasonal influenza vaccine when co-administered with VAX-31 to those elicited by a seasonal influenza vaccine alone. Secondary immunogenicity objective: Comparing immunoglobulin G (IgG) antibody responses (IgG geometric mean concentrations (GMCs)) elicited by VAX-31 across all 31 serotypes and serotype 20B when VAX-31 is co-administered with a seasonal influenza vaccine to those elicited by VAX-31 alone.
