Safety and Immunogenicity of Vi-CRM197 Vaccine Against S. Typhi in Adult (18-40 Years Old)

December 16, 2013 updated by: Novartis

A Phase I, Randomized, Single-Blind, Controlled, Single Center Study to Evaluate the Safety and Immunogenicity of the NVGH Glycoconjugate Vaccine Against S. Typhi in Adult Subjects 18 to 40 Years of Age.

This trial is aimed to evaluate the safety and immunogenicity profiles of a new Vi-CRM197 conjugate vaccine against S. Typhi in healthy human adults in comparison with the currently licensed Vi polysaccharide vaccine.

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 40 years (ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

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
Number of Subjects Reporting Any Post Immunization Reactions
Time Frame: During the 7-day period after vaccination
Solicited reactions collected during the 7-day period after vaccination are pain, erythema, induration, chills, malaise, myalgia, headache, arthralgia and fatigue.
During the 7-day period after vaccination
Number of Subjects Reporting Adverse Events
Time Frame: During the 28-day period after vaccination
During the 28-day period after vaccination
Number of Subjects Reporting Serious Adverse Events (SAEs)
Time Frame: During the 6-month period after vaccination
During the 6-month period after vaccination

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
