A Single Ascending Dose Study in Adults (Stage 1) and Single Ascending Dose-Finding Study (Stage 2) in Elderly Subjects With ASP3772, A Pneumococcal Vaccine

Completed · Phase 1/Phase 2

Conditions studied: Pneumonia, Bacterial, Healthy Volunteers, Pneumococcal Disease

In brief

The purpose of the study is to evaluate the safety, tolerability, and immunogenicity of 3 different dose levels of ASP3772 in comparison to the active comparator Prevnar 13® (PCV13) in adults 18 to 64 years of age in Stage 1. Stage 2 will evaluate the safety, tolerability, and immunogenicity of 3 different dose levels of ASP3772 in comparison to the active comparator PCV13 in elderly 65 to 85 years of age. In addition, Stage 2 will evaluate the immunogenicity of 3 different dose levels of ASP3772 relative to the response seen following administration of Pneumovax® 23 (PPSV23) for the serotypes not included in PCV13.

Stage 1: Subject is healthy male or female between 18 and 64 year of age inclusive, at screening.
Stage 2: Subject is a male or female between 65 and 85 years of age, inclusive, at screening who is healthy or has chronic controlled, stable disease with no change in disease severity, medical therapy and no hospitalization records in last 12 weeks as determined by medical history, physical examination and laboratory data.
A female subject is eligible to participate if not pregnant and at least 1 of the following conditions applies:
Not a woman of childbearing potential (WOCBP) OR
WOCBP who agrees to follow the contraceptive guidance at screening and for at least 28 days after the study vaccine administration.
Female subject must agree not to breastfeed starting at screening and for 28 days after the study vaccine administration.
Female subject must not donate ova starting at screening and for 28 days after the study vaccine administration.
A male subject with female partner(s) of childbearing potential must agree to use contraception at screening and for at least 28 days after the study vaccine administration.
Male subject must not donate sperm starting at screening and for 90 days after the study vaccine administration.
Male subject with a pregnant or breastfeeding partner(s) must agree to remain abstinent or use a condom for the duration of the pregnancy or time partner is breastfeeding at screening and for 28 after the study vaccine administration.
Subject agrees not to participate in another interventional study while participating in the present study.

You may not qualify if…

Subject has a known or suspected hypersensitivity to ASP3772, its comparators or any components of the formulations used.
Subject has had previous exposure with ASP3772.
Subject has had known previous exposure with PPSV23.
Subject has received PCV13 or any other licensed or investigational pneumococcal vaccine at any time. (Note: This exclusion criterion is not applicable to Group 3; those subjects 65 to 85 years of age who previously received immunization with PCV13. Prior PCV13 immunization should have taken place no less than 10 months and no more than 2 years prior to study vaccine administration. These subjects are eligible to be enrolled in the nonrandomized arm of Stage 2, Group 3.
Subject has a history of microbiologically-proven invasive disease caused by S. pneumoniae.
Subject has an immune disorder(s) (including autoimmune disease) and/or clinical conditions requiring immunosuppressive drugs.
Subject has any evidence of any unstable or active clinically significant cardiovascular, gastrointestinal, endocrine, hematologic, hepatic, immunologic, metabolic, urologic, pulmonary, neurologic, dermatologic, psychiatric, renal and/or other major disease or malignancy, e.g., uncontrolled hypertension, uncontrolled diabetes, heart failure, uncontrolled chronic obstructive pulmonary disease, end-stage renal disease.
Subject has history of illicit drug(s) or alcohol abuse that will interfere with the protocol requirements and/or a positive urine drug test (for Stage 1 subjects only) at screening.
Subject has any clinically significant history of allergic conditions including drug allergies, asthma or anaphylactic reactions, but excluding untreated asymptomatic seasonal allergies prior to study vaccine administration.
Subject has a coagulation disorder contraindicating intramuscular immunization.
Subject has a positive serology test for hepatitis B surface antigen (HBsAg), hepatitis A virus antibodies (immunoglobulin M), hepatitis C virus antibodies (anti-HCV) confirmed by reflex testing (HCV-RNA) or antibodies to human immunodeficiency virus (HIV) type 1 and/or type 2 at screening.
Subject has/had febrile illness (> 100.4°F oral equivalent) or symptomatic, viral, bacterial (including upper respiratory infection) or fungal (noncutaneous) infection within 1 week prior to day 1.
Subject has any clinically significant abnormality from the physical examination, ECG and clinical laboratory tests during screening.
Subject is unlikely to adhere to study procedures, keep appointments, is planning to relocate during the study or cannot be adequately followed for safety according to the protocol.
Subject has any other condition, which precludes the subject's participation in the study.
Subject has received any vaccines within 30 days prior of receipt of the study vaccine (exception: Influenza virus vaccine given according to recommended guidelines must be given at least 7 days prior to receiving study vaccine).
Subject has had significant blood loss, donated 1 unit (450 mL or more) or received transfusion of any blood or blood products within 60 days or donated plasma within 7 days prior to day 1.
Subject has received any systemically absorbed antibiotics during the 7-day period prior to day 1.
