Safety and Immunogenicity of V116 in Adults With Increased Risk for Pneumococcal Disease (V116-008)

A Phase 3, Randomized, Double-blind, Active Comparator-controlled Clinical Study to Evaluate the Safety, Tolerability, and Immunogenicity of V116 in Pneumococcal Vaccine-naïve Adults 18 to 64 Years of Age With Increased Risk for Pneumococcal Disease.

The primary objectives of this study are to evaluate the safety and tolerability of the pneumococcal 21 valent conjugate vaccine (V116), and to evaluate the serotype-specific opsonophagocytic activity (OPA) post-vaccination with V116 and PCV15 (a pneumococcal conjugate vaccine that includes 15 serotypes) + PPSV23 (comprised of the polysaccharides from 23 of the serotypes causing disease in adults) post-vaccination within each vaccination group separately.

Inclusion Criteria:

• Has documented result(s) of ≥1 of the following risk conditions for pneumococcal disease: diabetes mellitus, receiving treatment with ≥1 approved antidiabetic medication, with all Hemoglobin A1c (HbA1c) measurements ≤9% within 6 months before first study vaccination; compensated chronic liver disease; diagnosis of chronic obstructive pulmonary disease (COPD) managed per local guidelines; diagnosis of mild or moderate persistent asthma managed per local guidelines; confirmed diagnosis of chronic heart disease managed per local guidelines; confirmed diagnosis of chronic kidney disease (>3 months duration).
• Is receiving stable medical management for the listed risk conditions for ≥3 months with no anticipated major change in treatment expected for the duration of the study and with ≤1 hospitalization directly related to the risk condition.
• Female Is not a participant of childbearing potential (POCBP); or if a POCBP Uses an acceptable contraceptive method or is abstinent from penile-vaginal intercourse as their preferred and usual lifestyle (abstinent on a long-term and persistent basis); their medical history, menstrual history, and recent sexual activity has been reviewed by the investigator.

Exclusion Criteria:

• Has a history of active hepatitis.
• Has a history of diabetic ketoacidosis or 2 or more episodes of severe, symptomatic hypoglycemia within 3 months before first study vaccination (Day 1).
• Has a history of myocardial infarction, acute coronary syndrome, transient ischemic attack, or ischemic or hemorrhagic stroke within 3 months before first study vaccination (Day 1).
• Has a history of severe pulmonary hypertension with World Health Organization (WHO) functional class ≥3 or history of Eisenmenger syndrome
• Has a history of autoimmune related chronic kidney disease, chronic kidney failure, a reversible cause of kidney disease, nephrotic syndrome, or any ineligible Kidney Disease: Improving Global Outcomes (KDIGO)-recommended stage of glomerular filtration rate (GFR) and Albuminuria
• Has a history of invasive pneumococcal disease (IPD) (positive blood culture, positive cerebrospinal fluid culture, or positive culture at another sterile site) or known history of other culture-positive pneumococcal disease within 3 years before first study vaccination (Day 1).
• Has a known hypersensitivity to any component of V116, PCV15, or PPSV23, including diphtheria toxoid.
• Has a known or suspected impairment of immunological function including, but not limited to, congenital or acquired immunodeficiency, documented human immunodeficiency virus (HIV) infection, functional or anatomic asplenia, or autoimmune disease.
• Has a coagulation disorder contraindicating intramuscular (IM) vaccination.
• Had a recent febrile illness or received antibiotic therapy for any acute illness occurring within 72 hours before receipt of any study vaccine.
• Has a known malignancy that is progressing or has required active treatment <3 years before randomization.
• Has planned organ transplantation (heart, liver, lung, kidney, or pancreas) or other planned major surgical procedure during the duration of this study.
• Has expected survival for <1 year.
• Has received any prior pneumococcal vaccine or is expected to receive any pneumococcal vaccine during the study outside the protocol.
• Has received systemic corticosteroids (prednisone equivalent of ≥20 mg/day) for ≥14 consecutive days and has not completed intervention ≥14 days before receipt of study vaccine at Visit 2 (Day 1).
• Is currently receiving systemic immunosuppressive therapy, including chemotherapeutic agents or other immunotherapies/immunomodulators used to treat cancer or other conditions, and interventions associated with organ or bone marrow transplantation, or autoimmune disease.
• Has received any non-live vaccine ≤14 days before receipt of any study vaccine or is scheduled to receive any non-live vaccine ≤30 days after receipt of any study vaccine.
• Has received any live virus vaccine (including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) live virus vaccines) ≤30 days before receipt of any study vaccine or is scheduled to receive any live virus vaccine ≤30 days after receipt of any study vaccine
