Vaxcyte Reports First Quarter 2021 Financial Results and Provides Business Update

FOSTER CITY, Calif., May 11, 2021 (GLOBE NEWSWIRE) -- Vaxcyte, Inc. (Nasdaq: PCVX), a next-generation vaccine company seeking to improve global health by developing superior and novel vaccines designed to prevent or treat some of the most common and deadly infectious diseases worldwide, today announced financial results for the first quarter ended March 31, 2021 and provided a business update.

“Over the past few months, we have made good progress as we advance VAX-24, our 24-valent pneumococcal conjugate vaccine (PCV), toward the anticipated submission of the Investigational New Drug (IND) application in order to generate clinical proof-of-concept data,” said Grant Pickering, Chief Executive Officer and Co-founder of Vaxcyte. “While we remain laser-focused on delivering on our VAX-24 milestones, I am also very excited by the progress made to advance our pipeline vaccines, including VAX-XP, our PCV candidate with an expanded breadth of coverage, and VAX-A1, our novel conjugate vaccine designed to provide universal protection from Group A Strep infections.”

Recent Highlights

• Advanced VAX-24 IND-Enabling Activities: Vaxcyte continues to progress several initiatives for VAX-24 in connection with its anticipated IND application submission to the U.S. Food and Drug Administration (FDA) and ensuing Phase 1/2 clinical proof-of-concept study initiation. Among other activities, the Company made substantive progress toward completion of the final stage of production of the 24 good manufacturing practice (GMP) conjugated drug substances.
  
  
• Published New Research Supporting VAX-24 and Vaxcyte’s Technology Platform: Since the beginning of 2021, Vaxcyte published preclinical VAX-24 data as well as research supporting its technology platform. The papers can be accessed here: https://vaxcyte.com/posters-publications/.   
  
  
  • The paper, “Non-clinical Immunological Comparison of a Next-Generation 24-Valent Pneumococcal Conjugate Vaccine (VAX-24) Using Site-Specific Carrier Protein Conjugation to the Current Standard of Care (PCV13 and PPV23),” published in the journal Vaccine, uses a rabbit model to evaluate the immune response of Vaxcyte’s 24-valent PCV candidate compared to Prevnar13^® (PCV13) and Pneumovax^®23 (PPV23). In this study, all serotype conjugates (pneumococcal strains) in VAX-24 met the primary objective to elicit immune responses that were more robust compared to PPV23 and at least comparable to PCV13.
  • The paper, “Site‑specific antigen‑adjuvant conjugation using cell‑free protein synthesis enhances antigen presentation and CD8+ T‑cell response,” was published in the journal Scientific Reports, and demonstrated an enhanced CD8 positive T-cell response by directly conjugating an adjuvant to a candidate antigen. This expansion of Vaxcyte’s site-specific technology platform has potential application in viral vaccines where an enhanced CD8 T-cell response is required.
    
    
• Appointed Janet Graesser, Vice President, Corporate Communications and Investor Relations: In April 2021, Vaxcyte appointed Janet Graesser as Vice President of Corporate Communications and Investor Relations. Mrs. Graesser brings to Vaxcyte over 20 years of healthcare communications experience and expertise across a variety of areas, including corporate communications and strategy, public relations and organizational communications. She dedicated 13 years of her career working at leading healthcare communications firms, ultimately serving as an Executive Vice President, delivering communications strategy and implementation to biotech, pharmaceutical and consumer health companies, including Amgen, GlaxoSmithKline (GSK), Johnson & Johnson (J&J), Pfizer and Merck. She went on to hold an operating role at J&J with responsibility for internal and external communications across seven J&J medical device companies, including Cordis. Mrs. Graesser remained in a senior leadership role with Cordis when it was acquired by Cardinal Health, ultimately serving as the Vice President of Global Communications and Strategy Implementation. Mrs. Graesser went on to establish her own consulting practice that successfully supported both large and small biotech companies.
  

“I would also like to acknowledge the key role that Bill Newell, the Chief Executive Officer of Sutro Biopharma who will be stepping down from the board at the end of his term in June, has played in the creation of Vaxcyte,” said Mr. Pickering. “We are grateful for Bill’s quality stewardship as a director and his recognition that the cell-free protein synthesis platform could be more broadly applied, which was an instrumental catalyst in starting Vaxcyte.”

Anticipated Key Milestones

Vaxcyte reaffirmed its previously issued guidance for its pipeline programs.

• VAX-24: Vaxcyte expects to submit an IND application for VAX-24 to the FDA between January and June 2022. Vaxcyte expects to announce topline data from the ensuing Phase 1/2 clinical proof-of-concept study between late 2022 and early 2023.
  
  
• VAX-A1: Following the nomination of its final vaccine candidate for VAX-A1 in the first quarter of 2021, Vaxcyte plans to initiate IND-enabling studies in the second half of 2021.
  
  
• VAX-PG: Vaxcyte expects to nominate a final vaccine candidate for VAX-PG, its novel therapeutic vaccine designed to treat periodontal disease, in the second half of 2021.
  

First Quarter 2021 Financial Results

• Cash Position: Cash, cash equivalents and investments were $370.9 million as of March 31, 2021, compared to $386.2 million as of December 31, 2020.
  
  
• Research & Development (R&D) Expenses: R&D expenses were $17.3 million for the three months ended March 31, 2021 as compared to $24.3 million for the same period in 2020. The decrease was due primarily to a decrease in manufacturing expenses and outsourced research services related to Vaxcyte’s VAX-24 program as a result of the completion of the eCRM™ and polysaccharide GMP campaigns in 2020, partially offset by increases in VAX-24 drug substance and drug product activities and VAX-XP activities.
  
  
• General & Administrative (G&A) Expenses: G&A expenses were $5.9 million for the three months ended March 31, 2021 as compared to $3.3 million for the same period in 2020. The increase was due primarily to an increase in personnel-related and directors and officers liability insurance expenses.
  
  
• Net Loss: Net loss was $21.2 million for the three months ended March 31, 2021 as compared to $27.1 million for the same period in 2020.
  

About Vaxcyte
Vaxcyte is a next-generation vaccine company seeking to improve global health by developing superior and novel vaccines designed to prevent or treat some of the most common and deadly infectious diseases worldwide. The Company’s cell-free protein synthesis platform, comprising the XpressCF™ platform, exclusively licensed from Sutro Biopharma, Inc., together with Vaxcyte’s proprietary know-how, enables the design and production of protein carriers and antigens, the critical building blocks of vaccines, in ways that the Company believes conventional vaccine technologies currently cannot. Vaxcyte’s lead vaccine candidate, VAX-24, is a preclinical, 24-valent broad-spectrum pneumococcal conjugate vaccine (PCV) being developed for the prevention of invasive pneumococcal disease. Vaxcyte’s pipeline also includes VAX-XP, a PCV with an expanded breadth of coverage of at least 30 strains; VAX-A1, a prophylactic vaccine candidate designed to prevent Group A Strep infections; and VAX-PG, a therapeutic vaccine candidate designed to slow or stop the progression of periodontal disease by targeting the keystone pathogen responsible for this chronic, oral inflammatory disease.
