Safety and Immunogenicity of a Recombinant Poliomyelitis Vaccine (rPV) in Comparison With IPOL Vaccine in Healthy Adults

July 9, 2026 updated by: Serum Institute of India Pvt. Ltd.

A Phase 1, Double-blinded, Randomised, Active Controlled, Clinical Trial to Assess the Reactogenicity, Safety and Immunogenicity of a Recombinant Poliomyelitis Vaccine (rPV) in Comparison With IPOL Vaccine in Healthy Adults

The primary purpose of this study is to test a new experimental recombinant Poliomyelitis vaccine (rPV) in comparison to the commercially available inactivated poliovirus vaccine. The design of the study is double-blinded, randomised and active controlled. The active controlled product is considered the commercially available vaccine (IPOL).

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 study is a double-blinded, randomised, active controlled, Phase 1 clinical study, to determine the safety, tolerability, and reactogenicity of Serum Institute of India Pvt Ltd (SIIPL) rPV vaccine in comparison to the commercially available inactivated poliovirus vaccine (IPOL®, Sanofi) in up to 36 healthy adults aged between 18 and 60 years. This study will be conducted at a single study site in Australia.

Participants will be randomised in a 2:1 ratio, to receive either investigational vaccine (rPV) or comparator vaccine (IPOL), respectively. The study vaccine will be administered as a single intramuscular (IM) injection into the deltoid muscle of the non-dominant upper arm. The participants will be followed for 30 days post vaccination.

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

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
Time Frame
The incidence, severity and relationship of solicited adverse events (AEs) during 7-day and unsolicited AEs during 30-day follow-up period after rPV and IPOL vaccination
Time Frame: 30 days
30 days

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
Time Frame
Percentage of participants achieving seroprotection/seroconversion for poliovirus Types 1, 2 and 3, on Day 30.
