Summary
The study will evaluate the safety, tolerability and immunogenicity of a 13-valent pneumococcal conjugate vaccine (13vPnC) in HIV-infected subjects 18 years of age or older who have been previously immunized with at least one dose of 23-valent pneumococcal polysaccharide vaccine (23vPS). All subjects will receive 3 doses of 13vPnC, with each study vaccine dose given approximately 6 months apart.
Eligibility Criteria
Inclusion Criteria
- Male or female subjects aged 18 years or older at the time of enrollment.
- All female and male subjects who are biologically capable of having children must agree and commit to the use of a reliable method of birth control from the signing of the informed consent form (ICF) until 3 months after the last dose of investigational product.
- Documented vaccination with 1 or more doses of 23vPS at least 6 months before study enrollment.
- CD4+ T-cell count >= 200 cells/µ, obtained on the most recent 2 occasions within 6 months before the first investigational product vaccination.
- HIV-infected subjects with viral load 5 times the upper limit of normal within the last 6 months.
- Serious chronic disorder or any other disorder that, in the investigator's opinion, precludes the subject from participating in the study or interferes with the evaluation of the study objectives. (Note: Serious chronic disorders include metastatic malignancy, severe chronic obstructive pulmonary disease requiring supplemental oxygen, end-stage renal disease with or without dialysis, and clinically unstable cardiac disease).
- Any major illness/condition that, in the investigator's judgment, will substantially increase the risk associated with the subject's participation in and completion of, the study, or could preclude the evaluation of the subject's response.
- History of splenectomy.
- Receipt of any blood products, including immunoglobulin, within 42 days before investigational product vaccination until the last blood draw for the study (approximately 13 months after the first investigational product vaccination).
- Evidence of dementia or other severe cognitive impairment.
- Subject who is, in the opinion of the investigator, unable to receive a vaccination in the deltoid muscle of either arm because of insufficient muscle mass.
- Participation in another study using investigational product from 28 days before study enrollment until the blood draw at visit 6. Between the blood draw at visit 6 and the 6 month follow-up telephone call (visit 7), use of investigational product must be discussed with the Medical Monitor. (Note: Participation in purely observational studies is acceptable.)
- Residence in a nursing home, long-term care facility, or other institution or requirement of semi-skilled nursing care. An ambulatory resident of a retirement home or village is eligible for the trial.
- Subject who is a direct relative (child, grandchild, parent, or grandparent) of study personnel, or who is study personnel.
Temporary Delay Criteria:
- Current febrile illness (oral temperature of =38.0°C [100.4°F]) or other acute illness within 48 hours before study vaccine administration.
- Currently receiving antibiotic therapy, or has completed a course of antibiotic therapy within 10 days before study vaccine administration.
- Receipt of novel influenza A (H1N1) vaccine within 14 days before investigational product vaccination (seasonal influenza vaccine can be given at any time at the discretion of the investigator).
