SAN CARLOS, Calif., Aug. 08, 2023 (GLOBE NEWSWIRE) -- Vaxcyte, Inc. (Nasdaq: PCVX), a clinical-stage vaccine innovation company engineering high-fidelity vaccines to protect humankind from the consequences of bacterial diseases, today announced financial results for the second quarter ended June 30, 2023 and provided a business update.
“The need for vaccines that offer broader protection to prevent pneumococcal disease was recently reaffirmed by the Advisory Committee on Immunization Practices, and we believe the positive data from the VAX-24 adult Phase 2 clinical program support the potential best-in-class profile for our 24-valent PCV candidate to deliver broader coverage and improved immune responses compared to the standard-of-care,” said Grant Pickering, Chief Executive Officer and Co-founder of Vaxcyte. “Our strong balance sheet provides a solid foundation as we advance our PCV franchise and pipeline programs. We look forward to continued progress, including the finalization of our VAX-24 adult Phase 3 program and licensure requirements, and remain on track to deliver topline Phase 3 data in 2025.”
Key Second Quarter and Recent Highlights
- Completed VAX-24 Adult Phase 2 Program with Announcement of Positive Data in Adults 65 and Older and Full Six-Month Safety Data from Adult Phase 1/2 and Phase 2 Studies: In April 2023, Vaxcyte announced positive results from the VAX-24 Phase 2 study in adults aged 65 and older, as well as data from the full six-month safety assessment and prespecified pooled immunogenicity analyses from both the Phase 2 study in adults aged 65 and older and the prior Phase 1/2 study in adults aged 18-64. VAX-24, the Company’s lead, broad-spectrum 24-valent pneumococcal conjugate vaccine (PCV) candidate, is being studied for the prevention of IPD. In the Phase 2 study in adults aged 65 and older, VAX-24 demonstrated robust opsonophagocytic activity (OPA) immune responses across all 24 serotypes at all doses studied, confirming the prior Phase 2 adult study results. The VAX-24 2.2mcg dose, which Vaxcyte plans to advance to Phase 3, showed an overall improvement in immune responses vs. Prevnar 20® (PCV20) relative to the results from the prior Phase 2 study in adults aged 50-64. The six-month safety data from both studies showed safety and tolerability results for VAX-24 similar to PCV20 at all doses studied. Additionally, the prespecified pooled immunogenicity analyses of data from both adult Phase 2 studies showed the VAX-24 2.2mcg dose met the OPA non-inferiority criteria(1) for all 20 serotypes common with PCV20 and the superiority criteria(2) for the four additional VAX-24 serotypes.
- Advanced to Second and Final Stage of Phase 2 Study Evaluating VAX-24 for the Prevention of IPD in Infants and Dosed First New Participants: In July 2023, Vaxcyte announced that the ongoing Phase 2 study of VAX-24 in healthy infants advanced to the second and final stage of the study. The independent Data Safety Monitoring Board approved advancing to the second stage of the study following the review of the safety and tolerability results from the first stage. New participants were enrolled and dosed in Stage 2 of the study in July 2023. Additionally, in agreement with the U.S. Food and Drug Administration (FDA), Vaxcyte amended the study protocol for Stage 2, changing the study comparator to PCV20, which is currently the broadest-spectrum PCV recommended by the Advisory Committee on Immunization Practices.
- Completed Successful $575 Million Follow-On Financing: In April 2023, Vaxcyte completed an underwritten public offering of 13,030,000 shares of its common stock, which included the full exercise of the underwriters’ option to purchase additional shares, at a public offering price of $41.00 per share and pre-funded warrants to purchase 1,000,000 shares of common stock at a public offering price of $40.999 per underlying share. The aggregate gross proceeds to Vaxcyte from the offering were $575.2 million, before deducting underwriting discounts and commissions and other offering expenses payable by Vaxcyte and excluding the exercise of any pre-funded warrants.
- Published New VAX-GI Preclinical Data and Received NIH Grants: A paper entitled, “A Novel Shigella O-Polysaccharide–IpaB Conjugate Vaccine Elicits Robust Antibody Responses and Confers Protection against Multiple Shigella Serotypes,” was published in the April 2023 edition of mSphere featuring new preclinical data for VAX-GI, Vaxcyte’s novel Shigella vaccine candidate. These data demonstrated that with Vaxcyte’s cell-free technology, the Company believes it can produce the central antigen in VAX-GI, IpaB, at substantially improved yields, allowing for commercial-scale production of the target vaccine. Additionally, this research showed that the vaccine candidate was efficacious in preclinical models of Shigella infection. Shigella, which has no available preventative treatment, affects an estimated 188 million people worldwide each year and results in approximately 164,000 deaths. This vaccine candidate is being developed in collaboration with the University of Maryland, Baltimore as well as with partial funding from two National Institutes of Health research (R01) grants totaling $7.2 million.
“In early July, we were saddened by the sudden passing of Michael E. Kamarck, Ph.D., a member of our Board of Directors. Mike was a luminary in the biopharmaceutical industry, with long-standing, major contributions in vaccine and therapeutic product development and manufacturing that spanned over four decades. His desire to improve the lives of people around the world was evident through this commitment to public health and his support of companies large and small, on which he left a lasting mark. Mike’s compassionate nature extended far beyond his work as a beloved husband, father, grandfather and friend. We extend our deepest condolences to his family and all those he impacted throughout his life,” said Mr. Pickering.

Second Quarter 2023 Financial Results
- Cash Position: Cash, cash equivalents and investments were $1,440.8 million as of June 30, 2023, compared to $957.9 million as of December 31, 2022. The June 30, 2023 amount includes the $545.3 million in net proceeds from the follow-on offering completed in April 2023.
- Research & Development (R&D) Expenses: R&D expenses were $72.7 million for the three months ended June 30, 2023 as compared to $38.5 million for the same period in 2022.

- General & Administrative (G&A) Expenses: G&A expenses were $14.5 million for the three months ended June 30, 2023 as compared to $9.4 million for the same period in 2022. The increase was due primarily to higher personnel-related expenses related to an increase in G&A employees to support the growth of the Company.
- Net Loss: For the three months ended June 30, 2023, net loss was $68.3 million, compared to $48.5 million for the same period in 2022.
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 IPD. 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-31, a 31-valent PCV candidate; 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. For more information, visit www.vaxcyte.com.
