Study summary

This study is a randomized, open-labeled phase IV clinical trial to evaluate the immunogenicity and safety of concomitant administration of sIPV and DTaP or MMR in infants aged 2 months. Primary immunogenicity endpoints in all groups include the seroconversion rate of type I, II, and III anti-poliovirus neutralizing antibodies, anti-DT, anti-TT, anti-PT, anti-FHA, and anti-PRN antibodies 30 days after basic immunization. Secondary immunogenicity endpoints include the seropositive rates, seroconversion rates, geometric mean titer/concentration (GMT/GMC), geometric mean fold increase (GMFI) of type I, II, and III anti-poliovirus neutralizing antibodies, anti-DT, anti-TT, anti-PT, anti-FHA, and anti-PRN antibodies, and anti-measles, anti-mumps, and anti-rubella antibodies 30 days after full immunization. The secondary safety endpoints are the incidence of adverse events (AEs) within 30 minutes after each injection, the incidence of solicited local and systematic AEs in the period of solicitation after each injection, the incidence of unsolicited AEs in 30 days after each injection, the incidence of AEs in 30 days after each injection, and the incidence of serious adverse events in 6 months after administrations.

Read the detailed description

This is a randomized, open-labeled, parallel phase IV clinical trial to evaluate the immunogenicity and safety of concomitant administration of sIPV and DTaP or MMR. 2640 participants aged 2 months will be randomly assigned to 4 cohorts in a ratio of 1:1:1:1. [Cohort A] 660 infants will take administration of sIPV at 2, 3, 4, 18 months of age and DTaP at 2, 4, 6, and 18 months of age. sIPV and DTaP at 2, 4, and 18 months of age will be taken concomitantly. [Cohort B] 660 infants will take administration of sIPV at 2, 3 months of age, bOPV at 4 months and 4 years of age, and DTaP at 2, 4, 6, 18 months of age. sIPV/bOPV at 2, 4 months of age will be taken concomitantly. [Cohort C] 660 infants will take administration of sIPV at 2, 3, 4, 18 months of age, DTaP at 2, 4, 6, and 18 months of age, and MMR at 18 months of age. DTaP will be taken 7 days after sIPV at 2, 4, 18 months of age. Half participants will take concomitant administration of sIPV and MMR at 18 months of age, and the rest will take them separately (MMR at 19 months of age). [Cohort D] 660 infants will take administration of sIPV at 2, 3 months of age, bOPV at 4 months and 4 years of age, and DTaP at 2, 4, 6, 18 months of age. DTaP will be taken 7 days after sIPV/bOPV at 2, 4 months of age.

For immunogenicity assessment, blood samples on Day 0 and Day 30 after basic immunization of each kind of investigational vaccine would be collected to evaluate the type I, II, and III anti-poliovirus neutralizing antibodies, anti-DT, anti-TT, anti-PT, anti-FHA, and anti-PRN antibodies, and anti-measles, anti-mumps, and anti-rubella antibodies for different groups.

For safety assessment, adverse events after each dose would be recorded through the diary and contact cards by participants' guardians to collect solicited or unsolicited AEs in periods of solicitation and nonsolicitation, respectively. From 31 days after the final dose to 6 months later, serious adverse events will be evaluated by the investigator via phone call or active reports by participants' guardians.

Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Live vaccines

Vaccines made with a weakened form of the germ, such as measles–mumps–rubella (MMR), chickenpox and yellow fever. They can be risky when the immune system is weakened. Flu injections are not live; the nasal flu spray is.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 17, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
