Vaxcyte Reports Second Quarter 2021 Financial Results and Provides Business Update

FOSTER CITY, Calif., Aug. 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 second quarter ended June 30, 2021 and provided a business update.

"The public health community continues to affirm the need for vaccines that can offer broader protection to prevent pneumococcal disease and, importantly, reach an expanded population including adults aged 50 and older as well as those at higher risk due to existing health conditions," said Grant Pickering, Chief Executive Officer and Co-founder of Vaxcyte. "We are focused on making a significant contribution to fulfill this need with VAX-24, our lead, 24-valent pneumococcal conjugate vaccine (PCV) candidate, and VAX-XP, our PCV candidate with an expanded breadth of coverage."

Pickering continued, "We have made meaningful strides with VAX-24 in collaboration with Lonza, including the completion of the manufacturing and testing of the 24 conjugated drug substances (DS). We are well on our way to the final release of the DS and have now entered the final drug product (DP) formulation, fill and finish phase as we advance toward the anticipated submission of the Investigational New Drug (IND) application required to generate clinical proof-of-concept data."

Recent Highlights

• Advanced VAX-24 IND-Enabling Activities: Vaxcyte continues to progress several initiatives for VAX-24. The Company has manufactured and tested the 24 good manufacturing practice (GMP) conjugated DS and is now completing the final steps prior to release. Based upon the data collected to date, the Company has initiated the final process steps of GMP DP formulation, fill and finish leading to the anticipated IND filing.
  
  
  
  
• Received Additional Award from CARB-X to Advance VAX-A1: In August 2021, the Company received an additional award from CARB-X (Combating Antibiotic Resistant Bacteria Biopharmaceutical Accelerator) that commits $3.2 million in funding to advance development of VAX-A1, a novel conjugate vaccine designed to prevent infections caused by Group A Streptococcus pyogenes (Strep) bacteria. The award will fund IND-enabling work for VAX-A1. It also builds on the CARB-X award of $2.7 million for the initial funding period, which was completed in December 2020. Vaxcyte is eligible to receive up to a total of $29.7 million in CARB-X funding, inclusive of grants to date, upon the achievement of future VAX-A1 development milestones.
  
  
  
  
• Published New Research Supporting the Power of Vaxcyte's Technology Platform: The paper, "A Porphyromonas gingivalis Capsule-Conjugate Vaccine Protects From Experimental Oral Bone Loss," published in the July 2021 edition of the journal Frontiers in Oral Health, showed that conjugation of a polysaccharide from Porphyromonas gingivalis protects against oral bone loss in a mouse model of periodontal disease. This is another demonstration of the power of Vaxcyte's technology to enable site-specific conjugation of polysaccharides to a protein carrier in order to potentially generate robust and protective immune responses.

• Strengthened Advisory Board with Appointment of Dr. Emmanuel Walter from Duke University School of Medicine: In May 2021, Vaxcyte added Dr. Emmanuel Walter, MD, MPH, Professor of Pediatrics, of Duke University School of Medicine to its Scientific Advisory Board. In his roles as the Duke Human Vaccine Institute (DHVI) Chief Medical Officer and Director of the Duke Vaccine and Trials Unit, Dr. Walter provides strategic and operational leadership for clinical research conducted at the DHVI. In addition, he provides oversight of regulatory compliance for DHVI clinical research activities. Dr. Walter has dedicated his career to advancing research and clinical practice in vaccinology, infectious diseases and child health. He currently serves as the principal investigator for the Duke Clinical Core of the Collaborative Influenza Vaccine Innovations Centers funded by the National Institute of Allergy and Infectious Diseases (NIAID). Dr. Walter is the Duke Co-Principal Investigator for the NIAID Vaccine and Treatment Evaluation Unit, which conducts clinical trials of vaccines and treatments for infectious diseases. He is also the Duke Principal Investigator for the Centers for Disease Control and Prevention-funded Clinical Immunization Safety Assessment Project, which conducts studies to identify risk factors and preventive strategies for adverse events following immunization, particularly in special populations.
  
  

Anticipated Key Milestones

• VAX-24: Vaxcyte expects to submit an IND application for VAX-24 to the U.S. Food and Drug Administration (FDA) between January and June 2022. Vaxcyte anticipates announcing topline data between late 2022 and early 2023 from the ensuing Phase 1/2 clinical proof-of-concept study in adults aged 50 and older.
  
  
  
  
• 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 first half of 2022. The Company has updated its estimate for this milestone based on the extended timelines required to access certain critical components due to the COVID-19 pandemic, as well as the availability of research support to complete preclinical proof-of-concept studies.

Second Quarter 2021 Financial Results

• Cash Position: Cash, cash equivalents and investments were $341.0 million as of June 30, 2021, compared to $386.2 million as of December 31, 2020.
  
  
  
  
• Research & Development (R&D) Expenses: R&D expenses were $17.7 million for the three months ended June 30, 2021 as compared to $18.2 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, drug product and manufacturing scale-up activities and personnel-related expenses.
  
  
  
  
• General & Administrative (G&A) Expenses: G&A expenses were $6.1 million for the three months ended June 30, 2021 as compared to $3.0 million for the same period in 2020. The increase was due primarily to an increase in personnel-related and other expenses to support public company operations.
  
  
  
  
• Net Loss: Net loss was $23.7 million for the three months ended June 30, 2021 as compared to $20.3 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^TM 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.
