Title: Vaxcyte Advances Pneumococcal Disease Vaccine Programs in Q2 2025

In the second quarter of 2025, Vaxcyte, Inc. (Nasdaq: PCVX) reported significant progress in its vaccine pipeline, particularly for its pneumococcal disease programs. The company's focus on advancing its lead candidate, VAX-31, a potential best-in-class pneumococcal conjugate vaccine (PCV), was highlighted by key regulatory interactions and clinical milestones.

Vaxcyte's VAX-31 adult program saw substantial progress following interactions with the U.S. Food and Drug Administration (FDA). The company is finalizing its Phase 3 clinical program to validate VAX-31 as a potential new standard-of-care adult PCV to prevent invasive pneumococcal disease (IPD) and pneumonia. The pivotal, non-inferiority study, expected to be initiated in the fourth quarter of 2025, aims to demonstrate the vaccine's efficacy and safety. Topline data for this study is anticipated in 2026, aligning with previous guidance [1].

For the infant indication, Vaxcyte modified its ongoing VAX-31 Phase 2 dose-finding study to include a new dose arm designed to elicit even stronger immune responses. The modified study, expected to enroll approximately 900 participants by the end of the third quarter of 2025, will evaluate VAX-31's efficacy and safety in infants. Topline data from both the primary immunization series and the booster dose is expected by the end of the first half of 2027 [1].

Vaxcyte also streamlined its early-stage pipeline to prioritize resources for its PCV programs. The company paused the advancement of VAX-A1 and VAX-GI beyond preclinical development and discontinued further development of VAX-PG due to insufficient efficacy signals. This strategic move allows Vaxcyte to focus on its PCV franchise and extend its cash runway [1].

The company's financial position remains strong, with approximately $2.8 billion in cash, cash equivalents, and investments as of June 30, 2025. This robust financial backing enables Vaxcyte to continue its disciplined approach to capital allocation and support its PCV programs [1].

Key upcoming milestones for Vaxcyte's PCV franchise include initiating the Phase 3 pivotal, non-inferiority study for VAX-31 in the fourth quarter of 2025 and announcing topline data in 2026. Additionally, the company anticipates announcing the balance of the VAX-24 Phase 2 dose-finding study data by the end of 2025 and proceeding with the modified Phase 2 randomized, dose-finding study for VAX-31 by the end of the third quarter of 2025 [1].

Vaxcyte's progress in the second quarter underscores its commitment to advancing innovative vaccines to protect against bacterial diseases. The company's strategic focus on its PCV franchise, coupled with its strong financial position, positions Vaxcyte well for future growth and success.
