A Phase 3 interventional study of 5-dose group of test vaccine and 5-dose group of control vaccine in Rabies, sponsored by Ningbo Rongan Biological Pharmaceutical Co., Ltd.. Not yet recruiting at 4 sites in China. Open to participants aged 10 Years to 60 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2023-08-09.
Sponsored by Ningbo Rongan Biological Pharmaceutical Co., Ltd. · Phase 3, Interventional, and Prevention
This study was intended to explore the safety and immunogenicity of the test vaccine compared to the control vaccine. The trial consisted of two phases.
Phase I used an open-ended design. Phase II used a randomized, blinded, parallel-controlled non-inferiority design with the same type of active vaccine, in which the control vaccine 5-dose group and the test vaccine 5 group were kept blinded throughout, the test vaccine 4-dose B group was kept blinded from the other three groups until visit 4 (D14), and the test vaccine 4-dose A group was kept blinded from the control vaccine 5-dose group and the test vaccine 5-dose group until visit 5 (D28).
114 studies on the registry are indexed under Rabies; 15 are open to participants now.
This study's planned enrollment of 2,460 is above the median of 201 across 104 interventional studies indexed under Rabies.

Inclusion Criteria:
Exclusion Criteria:
Exclusion Criteria at 1-dose:
Due to various medical, psychological, social, or other conditions that, in the judgment of the investigator, are inconsistent with the study protocol or cannot be complied with.
For the criteria marked with an (*), if the subject has the conditions specified in that criteria, the visit may be rescheduled when those conditions are no longer present.
In addition to the examination items set by the protocol, other medical history, surgical history, and medication history were obtained in the form of consultation.
Criteria for subsequent dose delays:If any of the following conditions occur before any subsequent dose of the subject, the vaccination should be postponed until the vaccination requirements are met.

Exclusion criteria for immunopersistent blood collection:
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.
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.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
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.
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.
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.
