August 18, 2017 updated by: Crucell Holland BV

Phase 1, First in Human Study to Evaluate the Safety, Tolerability and Immunogenicity of Ad35.RSV.FA2 Regimens Boosted With Ad26.RSV.FA2 in Healthy Adult Volunteers

The purpose of this study is to assess the safety and tolerability of intramuscular homologous and heterologous prime-boost regimens of Ad35.RSV.FA2 (human adenovirus-vectored vaccine candidate) and Ad26.RSV.FA2 in healthy participants.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a single-center, randomized (study medication assigned to participants by chance), placebo-controlled (an inactive substance; a pretend treatment [with no drug in it] that is compared in a clinical trial with a drug to test if the drug has a real effect), double-blind (neither the researchers nor the participants know what treatment the participant is receiving) and Phase 1 study in healthy participants. The study comprises a 4-week screening period; vaccination for each participant on Days 1, 85, and, 169; a 28-day follow-up period performed after each vaccination and a final visit at Day 323 or 351. Participants will be randomly assigned to one of the 4 treatment groups (Group 1/2/3/4) to receive either Ad35.RSV.FA2 or Ad26.RSV.FA2 or placebo. The study duration will be approximately 52 weeks. Blood samples for immunogenicity will be collected. Participant's safety will be evaluated throughout the study.

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

18 years to 50 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

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
Solicited Local and Systemic Adverse Events (AEs)
Time Frame: Up to 8 days after each vaccination
Solicited AEs are precisely defined events that participants are specifically asked about and which are noted by participants through the participant diary.
Up to 8 days after each vaccination
Unsolicited AEs
Time Frame: From Signing of informed consent up to 28 days after each vaccination
Unsolicited AEs will be reported by the participant from when the informed consent form (ICF) is signed until 28 days after each vaccination, or early discontinuation.
From Signing of informed consent up to 28 days after each vaccination
Serious Adverse Events (SAEs)
Time Frame: Up to Day 337
A serious adverse event (SAE) is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly
Up to Day 337

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
Determination of Respiratory Syncytial Virus (RSV)-Specific Humoral Immune Response
Time Frame: Day 1 (predose) up to day 337
Determine induction and persistence of humoral immune response against RSV F-protein.
Day 1 (predose) up to day 337
To Assess RSV-specific Cellular Immune Response
Time Frame: Day 1 (predose) up to day 337
Assess the quantity and quality of the elicited cellular immune response.
Day 1 (predose) up to day 337

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
