About this study

Official title: A Phase 1, Randomized, Double-Blind, Placebo-Controlled, Dose Escalation Study to Evaluate the Safety, Tolerability, and Immunogenicity of GEN-004, a Streptococcus Pneumoniae Protein Subunit Vaccine, in Adult Subjects

GEN-004 is a combination of 3 conserved proteins from Streptococcus pneumoniae. This is a randomized, double-blind, placebo-controlled, dose escalation study. Eligible subjects (male and non-pregnant female) will be assigned sequentially to 1 of 3 dose cohorts and randomized in a 3:1:1 ratio to receive GEN-004 with adjuvant, GEN-004 without adjuvant, or placebo, respectively. Each subject will receive up to 3 doses at 4 week intervals.

Subjects will be followed for safety, tolerability, and immunogenicity for 12 months after their last dose.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To evaluate the safety and tolerability of GEN-004 when administered with and without aluminum hydroxide to adult subjects.

    Measured: 12 months after third (last) dose

Secondary outcomes (2)
  1. To evaluate the immunogenicity of GEN-004, as measured by TH17 (IL-17) and IgG responses to the antigens, when administered with and without aluminum hydroxide.

    Measured: 12 months after third (last) dose

  2. To evaluate the durability of immune responses up to 12 months after the last dose.

    Measured: 12 months after third (last) dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GEN-004 Low Dose, GEN-004 Low Dose + Adjuvant and GEN-004 Mid Dose in people with Streptococcus Pneumoniae, run by Genocea Biosciences, Inc. at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 Dec 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To evaluate the safety and tolerability of GEN-004 when administered with and without aluminum hydroxide to adult subjects. (time frame: 12 months after third (last) dose). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Dec 2015.
