Subjects who, in the opinion of the investigator, can and will comply with the requirements of the protocol.
-
Written informed consent obtained from the subject.
-
A male or female between, and including, 18 and 40 years of age at the time of the first vaccination.
-
Healthy subjects as established by medical history, physical examination and laboratory assessment before entering into the study.
-
Female subjects of non-childbearing potential may be enrolled in the study.
-
Female subjects of childbearing potential may be enrolled in the study, if the subject:
- has practiced adequate contraception for 30 days prior to vaccination, and
- has a negative pregnancy test on the day of vaccination, and
- has agreed to continue adequate contraception during the entire treatment period and for 2 months after completion of the vaccination series.
Exclusion Criteria
- Use of any investigational or non-registered product other than the study vaccines within 30 days preceding the first dose of study vaccines, or planned use during the study period.
- Concurrently participating in another clinical study, at any time during the study period, in which the subject has been or will be exposed to an investigational or a non-investigational vaccine/product.
- Planned administration/administration of a vaccine/product not foreseen by the study protocol in the period starting 30 days before the first vaccine dose and ending 30 days after the last dose of vaccines.
- Previous vaccination with a vaccine containing NTHi antigens.
- Chronic administration of immunosuppressants or other immune-modifying drugs within six months prior to the first vaccine dose, or equivalent. Topical steroids are allowed.
- Administration of immunoglobulins and/or any blood products within the 3 months preceding the first dose of study vaccines or planned administration during the study period.
- Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination.
- Laboratory evidence of clinically significant haematological (complete blood cell count [Red Blood Cells (RBC), White Blood Cells (WBC)], WBC differential count, platelets count and haemoglobin level) and biochemical (Alanine Aminotransferase [ALT], Aspartate Aminotransferase [AST], creatinine and lactate dehydrogenase [LDH]) abnormalities as per the opinion of the investigator based on the local laboratory normative data.
- Acute disease and/or fever at the time of enrolment.
- Acute or chronic, clinically significant pulmonary, cardiovascular, hepatic or renal functional abnormality, as determined by physical examination or laboratory screening tests.
- History of or current condition preventing intramuscular injection as bleeding or coagulation disorder.
- Malignancies within previous 5 years (excluding non-melanic skin cancer) and lymphoproliferative disorders.
- Pregnant or lactating female.
- Female planning to become pregnant or planning to discontinue contraceptive precautions.
- History of chronic alcohol consumption and/or drug abuse.
- Any other condition that the investigator judges may interfere with study findings.

- Primary Outcome Measures
Name Time Method Occurrence of any serious adverse event (SAE), in all subjects, in all vaccine groups From first vaccination to study conclusion (Day 420). Occurrence of solicited local and general adverse event (AE), in all subjects, in all vaccine groups During a 7-day follow-up period (i.e. day of vaccination and 6 subsequent days) after each vaccination. Occurrence of any unsolicited AE, in all subjects, in all vaccine groups During a 30-day follow-up period (i.e. day of vaccination and 29 subsequent days) after each vaccination. Occurrence of any potential Immune-Mediated Disease (pIMDs) in all subjects, in all vaccine groups From first vaccination to study conclusion (Day 420). Occurrence of haematological and biochemical laboratory abnormalities, in all subjects, in all vaccine groups At baseline (Screening visit) and after each vaccination.
- Secondary Outcome Measures
Name Time Method Humoral immune response to components of the NTHi vaccine formulations, in all subjects, in all vaccine groups Prior to each vaccination and 30 days post each vaccination.
