A Phase 3, Randomized Trial Investigating the Safety, Tolerability, and Immunogenicity of V116, an Adult-Specific Pneumococcal Conjugate Vaccine, in Pneumococcal Vaccine-Naïve Adults 18–64 Years of Age at Increased Risk of Pneumococcal Disease, STRIDE-8
Bibliographic record
Abstract
BACKGROUND: Pneumococcal disease (PD) is a major cause of hospitalization and mortality in adults. Individuals with certain chronic illnesses are at increased risk for PD. METHODS: This phase 3, randomized, double-blind, active comparator-controlled trial (NCT05696080) evaluated the safety and immunogenicity of 21-valent pneumococcal conjugate vaccine (V116) in adults 18-64 years of age with ≥1 condition associated with increased risk of PD (diabetes mellitus or kidney, heart, liver, or lung disease). Participants were given a single dose of either V116 followed by placebo or 15-valent pneumococcal conjugate vaccine (PCV15), followed by 23-valent pneumococcal polysaccharide vaccine (PPSV23) 8 weeks later. Immune responses were evaluated by opsonophagocytic activity (OPA) geometric mean titers (GMTs) and immunoglobulin G (IgG) geometric mean concentrations (GMCs) at 30 days postvaccination (day 30 for V116; week 12 for PCV15 + PPSV23). Proportions of participants who experienced adverse events (AEs) within 5 days postvaccination and serious AEs (SAEs) or deaths during the study were assessed. RESULTS: V116 was immunogenic for all 21 serotypes contained in the vaccine. OPA GMTs and IgG GMCs following V116 vaccination were comparable to PCV15 + PPSV23 for the 13 serotypes common between vaccine groups. For the eight serotypes unique to V116, immune responses were higher following V116 compared with PCV15 + PPSV23. V116 was well tolerated compared with PCV15 + PPSV23; no vaccine-related SAEs or deaths were reported. CONCLUSIONS: V116 elicits robust immune responses and is well tolerated in adults 18-64 years of age with conditions associated with an increased risk of PD.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
