Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

60 years to 70 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Male or female between 60 and 70 (inclusive) years of age at the time of vaccination.
  • Subject who is willing and able to comply with the requirements of the protocol (e.g. completion of the diary cards, return for follow-up visits).
  • Signed informed consent obtained from the subject.

Exclusion Criteria:

  • Health condition that, in the opinion of the investigator, may interfere with optimal participation in the study or place the volunteer at increased risk of adverse events (AEs). Study clinicians, in consultation with the principal investigator, will use clinical judgment on a case-by-case basis to assess safety risks under this criterion. The PI will consult with the medical monitor as appropriate. • Clinically significant abnormalities on physical examination.
  • Clinically significant abnormalities on laboratory screening.

  • History of radiologically documented pneumonia or invasive pneumococcal disease (IPD) within 3 years previous to study start, as reported by subject.
  • Known hypersensitivity to any components of the pneumococcal conjugate vaccine.
  • Previous vaccination with any pseudomonas investigational vaccine as reported by the subject.
  • Known or suspected impairment of immunological function, documented Human Immunodeficiency Virus (HIV) infection, asplenia, or history of autoimmune disease.
  • History of regular use (>2 weeks) in the last 6 months of immunosuppressive drugs including systemic corticosteroids (e.g. corticosteroids ≥0.5 mg/kg BW/day, excluding inhaled and topical steroid).
  • Has a coagulation disorder contraindicating intramuscular vaccination..
  • Received or receiving immunosuppressive therapy, including chemotherapeutic agents used to treat cancer or other conditions, and treatments associated with organ or bone marrow transplantation or autoimmune disease.
  • Received a blood transfusion or previous treatment with blood products, including immunoglobulins within the 3 months preceding the injection, or is scheduled to receive them within 30 days after vaccination.
  • Use of any investigational or non-registered product (drug or vaccine) other than the study vaccine(s) within 3 months preceding the administration of study vaccine, or planned use during the study period.
  • BMI (Body Mass Index) <19 or ≥35.
  • Positive blood test for HBsAg, hepatitis C virus (HCV), HIV-1/2.
  • History of allergy to any vaccine.
  • Use of any antibiotic therapy within 1 week preceding injection.
  • Subjects with an elective surgical intervention, planned during the study period.
  • History of chronic alcohol consumption and/or drug abuse.
  • Blood donation of at least 500 mL blood draw within 3 months preceding injection or planned during the study period as reported by subject.
  • Pregnancy or intention to become pregnant as reported by subject.
  • Female subjects who are not postmenopausal for at least 2 years.
  • Man subjects with a female partner in reproductive age refusing to use contraception methods.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Incidence of adverse events
Time Frame: until one month after injection
Safety and tolerability of the candidate vaccine as determined by occurrence, severity, relationship, of solicited and unsolicited advers events (AEs) and serious adverse events (SAEs) after injection of the candidate vaccine compared to the control group throughout the study until one month after injection.
until one month after injection

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Clinical laboratory abnormality measure
Time Frame: change from baseline one week after injection and one month after injection
Safety of the candidate vaccine by measuring changes in haematological and biochemical safety parameters before injection (baseline) and after vaccine administration, in terms of absolute changes and between groups.
change from baseline one week after injection and one month after injection
Assess immunogenicity of the candidate vaccine
Time Frame: one month and six months after injection
Evaluation of antigen-specific antibodies levels and functionality at each time point for all groups in terms of change from baseline
one month and six months after injection
