Clinical Trial Summary

The proposed phase IIb randomized, open label, dose ranging, safety and immunogenicity study will evaluate two different doses of 13-valent pneumococcal conjugate vaccine (PCV13) in two groups of participants (55 through 74 years of age). First group vaccine naïve participants will be open-label to receive a single injection of 0.5 mL PCV13. Second group of participant previously vaccinated with 23-valent pneumococcal polysaccharide vaccine (PPSV23) will be randomized 1:1 to receive two injections of 0.5 mL PCV13, one dose in each arm (Group IIA or Group IIB). Blood samples will be obtained at baseline, at one month and six months post-vaccination. The primary objectives are: to determine if two 0.5 mL doses of PCV13 are statistically significantly more immunogenic than a single 0.5 mL dose of PCV13 for at least some of the vaccine serotypes among participants 55 through 74 years of age previously vaccinated with PPSV23, as measured by serotype-specific OPA titers 28 days after study


Description:

This is a phase IIb open-label immunogenicity and safety study to evaluate dosages of 0.5 mL and 1.0 mL (given as two 0.5 mL injections in separate arms) of PCV13 in adults 55 through 74 years of age previously vaccinated with PPSV23. The study will enroll two groups of participants. Group I participants will all receive an open-label dose of 0.5 mL PCV13 and will include 294 adults 55-74 years of age who have not previously received 23-valent pneumococcal polysaccharide vaccine (PPSV23). Group II will be randomized 1:1 to receive 0.5 mL PCV13 (Group IIA) or 0.5 mL PCV13 in the right arm and 0.5 mL PCV 13 in the left arm (Group IIB). Group II will include 588 adults 55 through 74 years of age who previously received a single dose of PPSV23 > /=3 years and < /=7 years prior to enrollment. Enrollment in both groups will be stratified by age group (55 through 64 years and 65 through 74 years).The study duration is approximately 18 months. The primary objectives are: to determine if two 0.5 mL doses of PCV13 are statistically significantly more immunogenic than a single 0.5 mL dose of PCV13 for at least some of the vaccine serotypes among participants 55 through 74 years of age previously vaccinated with PPSV23, as measured by serotype-specific OPA titers 28 days after study vaccination, and is non-inferior to 12 vaccine serotypes; and determine if two 0.5 mL doses of PCV13 administered to participants previously vaccinated with PPSV23 are non-inferior to a single dose of 0.5 mL of PCV13 administered to vaccine-naïve adults 55 through 74 years of age for the 12 vaccine serotypes, as measured by serotype-specific OPA titers 28 days after study vaccination. The secondary objectives of this study are to: determine if two x 0.5mL doses of PCV13 is statistically significantly more immunogenic than a single 0.5 mL dose of PCV13 for at least some of the vaccine serotypes among participants 55 through 74 years of age previously vaccinated with PPSV23, as measured by serotype-specific OPA titers 180 days after study vaccination, and is non-inferior to 12 vaccine serotypes; to determine if two x 0.5mL doses of PCV13 administered to participants previously vaccinated with PPSV23 is non-inferior to a single dose of 0.5 mL of PCV13 administered to vaccine-naïve adults 55 through 74 years of age for 12 vaccine serotypes, as measured by serotype-specific OPA titers 180 days after study vaccination.

Eligibility Inclusion Criteria:

1. Male or female adults 55 through 74 years of age at the time of enrollment who are able to provide informed consent.

2. For the pneumococcal vaccine-naïve group (Group I), no pneumococcal vaccine received prior to enrollment, as documented by participant report and review of available vaccine records. For the previously vaccinated group (Group II), documented vaccination with exactly one dose of PPSV23 administered >/=3 and </=7 years prior to enrollment and no other lifetime doses of PPSV23. (History of receipt or non-receipt of a pneumococcal vaccine may be presumptively ascertained by participant report but must be confirmed by review of primary source information, including but not limited to medical records, primary care or other provider report, and health department records. Medical records should be reviewed and/or primary care or other providers queried to identify pneumococcal vaccinations administered for a period of not less than 10 years prior to enrollment.)

3. Determined by medical history, targeted physical examination (if indicated), and clinical judgment to be eligible for the study. Subjects with preexisting stable disease, defined as disease not requiring significant change in therapy (A change in dose or therapy within a category (e.g., change from one nonsteroidal anti-inflammatory drug to another) is allowed. A change to a new therapy category (e.g. surgery or addition of a new pharmacological class) is only allowed if it is not caused by worsening disease.) or hospitalization for worsening disease 12 weeks prior to enrollment, are eligible.

4. Agree not to receive a live virus vaccine (for example, zoster vaccine) before the Day 28 (Visit 03) blood specimen collection and not to receive an inactivated vaccine (for example, inactivated influenza vaccine) within 14 days after enrollment.

5. The subject is able to understand and comply with the planned study procedures including being available for all study visits.

6. The subject has provided informed consent prior to any study procedures.

Exclusion Criteria:

1. Receipt of any PCV or investigational pneumococcal vaccine prior to enrollment.

2. Receipt of any inactivated vaccine within 14 days prior to enrollment or receipt of any live vaccine within 30 days prior to enrollment.

3. Receipt of an allergy desensitization injection within 14 days prior to enrollment or planned receipt of an allergy desensitization injection within 7 days following enrollment.

4. Receipt of a diphtheria toxoid containing vaccine (for example, tetanus and diphtheria toxoid [Td] or tetanus and diphtheria toxoid and acellular pertussis [TdaP] vaccine) within six months prior to enrollment.

5. Known or suspected immunodeficiency, receipt of cancer chemotherapy or radiation therapy within the preceding 36 months, or receiving treatment with immunosuppressive therapy, including systemic corticosteroids, e.g., for cancer, HIV or autoimmune disease. If any systemic (oral, parenteral) corticosteroids have been administered for treatment of acute illness within 30 days of vaccination, and any long term use (>2 weeks) in the 30 through 59 days before vaccination should be excluded. (Topical, intranasal, and inhaled corticosteroids are allowed.)

6. Serious chronic disorders including active or metastatic malignancy, hematologic malignancy, severe chronic obstructive pulmonary disease or clinically significant congestive heart failure, requirement for supplemental oxygen, end stage renal disease with or without dialysis, clinically unstable cardiac disease, or any other disorder that in the opinion of the investigator precludes the subject's participation.
