Brief Summary

This study will evaluate the safety, tolerability, and immunogenicity of a pneumococcal 21-valent conjugate vaccine (V116) in persons living with human immunodeficiency virus (HIV), for the prevention of pneumococcal disease caused by the serotypes in the vaccine.

Outcome Measures

Primary Outcomes (4)

  • Percentage of Participants With Solicited Injection-site AEs From Day 1 Through Day 5 Postvaccination in Part A

    An adverse event (AE) is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The percentage of participants with solicited injection-site AEs after any vaccination was assessed. The solicited injection-site AEs assessed were redness/erythema, swelling, and tenderness/pain.

    Up to 5 days after each vaccination in Part A

  • Percentage of Participants With Solicited Systemic AEs From Day 1 Through Day 5 Postvaccination in Part A

    An adverse event (AE) is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The percentage of participants with solicited systemic AEs was assessed following any vaccination. The solicited systemic AEs assessed were fatigue, headache, myalgia, and pyrexia.

    Up to 5 days after each vaccination in Part A

  • Percentage of Participants With Vaccine-related Serious Adverse Events (SAEs) From Day 1 Through the Duration of Participation in Part A

    A serious adverse event (SAE) is an AE that is life-threatening, requires or prolongs an existing hospitalization, results in persistent or significant disability or incapacity, is a congenital anomaly or birth defect, or is another important medical event deemed such by medical or scientific judgment. Relatedness of an SAE to the study vaccine was determined by the investigator. Following any vaccination, the percentage of serious adverse events was assessed.

    Up to 194 days in Part A

  • Serotype-specific Opsonophagocytic Activity (OPA) Geometric Mean Titers (GMT) Postvaccination in Part A for 13 Serotypes Common Between V116 and PCV15 + PPSV23 and 8 Serotypes Unique to V116

    Serotype-specific OPA to the 13 serotypes common between V116 and PCV15 + PPSV23 and 8 serotypes unique to V116 were determined using a multiplex opsonophagocytic assay (MOPA). GMT is defined as geometric mean titer (1/dil). Serotype-specific OPA GMTs with 95% confidence intervals are presented.

    Up to 114 days

Secondary Outcomes (8)

  • Serotype-specific Immunoglobulin G (IgG) Geometric Mean Concentration (GMC) Postvaccination in Part A for 13 Serotypes Common Between V116 and PCV15 + PPSV23 and 8 Serotypes Unique to V116

    Up to 114 days

  • Serotype-specific OPA Geometric Mean Fold Rises (GMFRs) Postvaccination in Part A for 13 Serotypes Common Between V116 and PCV15 + PPSV23 and 8 Serotypes Unique to V116

    Baseline, 30 days post vaccination day 1 (V116), and 30 days post vaccination week 8 (PCV15 + PPSV23)

  • Serotype-specific IgG GMFRs Postvaccination in Part A for 13 Serotypes Common Between V116 and PCV15 + PPSV23 and 8 Serotypes Unique to V116

    Baseline, 30 days post vaccination day 1 (V116), and 30 days post vaccination week 8 (PCV15 + PPSV23)

  • Percentage of Participants With a >=4-fold Rise in OPA Responses From Baseline (Day 1) to Postvaccination in Part A for 13 Serotypes Common Between V116 and PCV15 + PPSV23 and 8 Serotypes Unique to V116

    Baseline, 30 days post vaccination day 1 (V116), and 30 days post vaccination week 8 (PCV15 + PPSV23)

  • Percentage of Participants With a >=4-fold Rise in IgG Responses From Baseline (Day 1) to Postvaccination in Part A for 13 Serotypes Common Between V116 and PCV15 + PPSV23 and 8 Serotypes Unique to V116

    Baseline, 30 days post vaccination day 1 (V116), and 30 days post vaccination week 8 (PCV15 + PPSV23)
