Effect of ERIG Injection on Day 7 After First Dose of Rabies Vaccination to Rabies Immune Response
A study testing Equine rabies immunoglobulin injection on day 7 in people with Rabies, run by Queen Saovabha Memorial Institute at 1 site in Thailand.
Trial summary
No study was conducted to evaluate the rabies neutralizing antibody titers after RIG injection on day 7. The only study that has supported the delay of RIG administration was done in 1996 by our institute, of which RIG was given on day 5 with the original Thai Red Cross intradermal regimen (2-2-2-0-1-1).

About this study
Official title: Effect of Equine Rabies Immunoglobulin Injection on Day 7 After First Dose of Rabies Vaccination to Rabies Immune Response
No study was conducted to evaluate the rabies neutralizing antibody titers after RIG injection on day 7. The only study that has supported the delay of RIG administration was done in 1996 by our institute, of which RIG was given on day 5 with the original Thai Red Cross intradermal regimen (2-2-2-0-1-1).
Read the detailed description
Rabies immunoglobulin (RIG) should be administered as soon as possible after the initiation of post-exposure prophylaxis. RIG should not be given after day 7 following the first rabies vaccine dose, because circulating neutralizing antibody will have begun to appear. Nevertheless, no study was conducted to evaluate the rabies neutralizing antibody titers after RIG injection on day 7.
The only study that has supported the delay of RIG administration was done in 1996 by our institute, of which RIG was given on day 5 with the original Thai Red Cross intradermal regimen (2-2-2-0-1-1). The ongoing study would prove the validity of the recommendation and eliminate the controversies in clinical practice.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Equine rabies immunoglobulin injection on day 7Biological
The patients with WHO category III rabies exposure, who have received first dose of rabies vaccination a week before and have not received rabies immunoglobulin were enrolled. Blood for Rabies neutralizing antibody titers (RNab) would be examined on day 0. On the same day, Equine rabies immunoglobulin (ERIG) at the dosage of 40 IU/kg would be injected into and around the wound as much as possible and the rest would be injected intramuscularly at the site distance from rabies vaccine. Then blood for RNab would be serially examined on day 7, 14, 90, 365.

What is being measured
The primary outcome is the main question the study is designed to answer.
Rabies neutralizing antibody titers
Rabies neutralizing antibody titers would be represented and compared by geometric mean titers (GMTs)
Measured: Change from baseline of geometric mean titres of rabies neutralizing antibody titres at 2 weeks

What does the primary outcome measure?
Rabies neutralizing antibody titers (time frame: Change from baseline of geometric mean titres of rabies neutralizing antibody titres at 2 weeks). 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.
