We are experiencing 4 week turn-around time in review of submissions and resubmissions. We recommend commencing this process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission. We currently do not have the capacity to expedite reviews.

Note also there are delays to review of updates. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Eligibility
Key inclusion criteria
1. Males and females 60 through 80 years of age who are ambulatory and live in the
community or in an assisted-living facility that provides minimal assistance, such
that the subject is primarily responsible for self-care and activities of daily
living. Subjects may have one or more chronic medical diagnoses, but should be
clinically stable as assessed by:

- Absence of changes in medical therapy within one month due to treatment failure
or toxicity (dose adjustments of ongoing therapies for optimal effect, or
replacements within a class of drugs due to convenience or cost, will be deemed
acceptable),

- Absence of medical events qualifying as SAEs within one month of the planned
vaccination on Day 0, and

- Absence of known, current, and life-limiting diagnoses which, in the opinion of
the investigator, render survival to completion of the protocol unlikely.

2. Willing and able (on both a physical and cognitive basis) to give informed consent
prior to study enrollment. To complete the consent process, all qualifying subjects
will correctly answer at least 4 out of 5 questions of the informed consent form (ICF)
comprehension assessment in no more than 2 attempts.

3. Able to comply with study requirements. As the protocol procedures involve telephone
contacts for safety ascertainment, eligible subjects must have a reliable access to a
telephone.
Minimum age
60 Years
Maximum age
80 Years
Gender
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
1. Received any prior RSV vaccine.

2. Participation in research involving any additional investigational product (drug /
biologic / device) within 45 days before planned date of first vaccination.

3. History of a serious reaction to any prior vaccination or a history of Guillain-Barré
syndrome (GBS) within 6 weeks of any prior influenza immunization.

4. Receipt of inactivated influenza vaccine within 14 days prior to the Day 0 dose of
test article or any other vaccine within the 4 weeks prior to the Day 0 dose of test
article.

5. Any known or suspected immunosuppressive condition, acquired or congenital, as
determined by history and/or physical examination.

6. Chronic administration (defined as more than 14 continuous days) of immunosuppressants
or other immune-modifying drugs within 6 months prior to the administration of the
study vaccine. An immunosuppressant dose of glucocorticoid will be defined as a
systemic dose = 10 mg of prednisone per day or equivalent. The use of topical,
inhaled, and nasal glucocorticoids will be permitted.

7. Administration of immunoglobulins and/or any blood products within the 3 months
preceding the administration of the study vaccine or during the study.

8. Acute disease at the time of enrollment (defined as the presence of a moderate or
severe illness with or without fever, or an oral temperature = 38.0°C on the planned
day of vaccine administration).

9. Known disturbance of coagulation. Potential subjects receiving aspirin, clopidogrel,
prasugrel, dipyridamole, dabigatran, apixaban, rivaroxaban, or warfarin under good
control for cardiovascular prophylaxis or prophylaxis of thromboembolic disease or
stroke in the setting of atrial fibrillation will NOT be excluded.

10. Suspicion or recent history (within one year of planned vaccination) of alcohol or
other substance abuse.

11. Any condition that in the opinion of the investigator would pose a health risk to the
subject if enrolled or could interfere with evaluation of the vaccine or
interpretation of study results (including neurologic, cognitive, or psychiatric
conditions deemed likely to impair the quality of study compliance or safety
reporting).

Summary
Brief summary
This is a randomized, observer-blind, trial in clinically-stable older adults. Up to 300
eligible older adults 60 through 80 years of age will be enrolled at a 1:1 ratio into
multiple dose/formulation treatment arms. Safety and immunogenicity data through Day 56 will
be used to select a vaccine candidate to potentially evaluate in a Part 2 study. Proportions
of subjects in various strata will not be pre-specified and the goal will be to achieve an
approximately equal distribution of subjects with these characteristics across the treatment
groups. Serology measures consistent with the study outcomes will be reported.
