A Comparator-controlled Study of the Safety and Neutralizing Activity of a Human Monoclonal Antibody to Rabies (SII RMAb) Administered in Conjunction with Rabies Vaccine for Post-exposure rabies Prophylaxis
- Conditions
- Potential Rabies exposure
- Registration Number
- CTRI/2012/05/002709
- Lead Sponsor
- Serum Institute of India Ltd Pune India
- Brief Summary
This will be a single-blind, randomized, and comparator-controlled clinical study. Safety and neutralizing activity of SII RMAb will be compared to licensed HRIG when administered with RABIVAX® according to WHO recommended PEP regimen.
The study will be conducted in two parts. In Part 1, 50 patients with low risk Category III wounds only will be randomized. Enrollment will initially be restricted to adults. An interim analysis of safety data from the first 10 adults through day 14 will be presented to the DCGI for review and permission to enroll children will be sought. Enrollment of adult males/ post menopausal females in the study will continue during this time. Enrollment of children equal to or more than 5 years old, however, will begin only after permission from the DCGI has been received. Based on an interim analysis for futility for Day 14 anti-rabies neutralizing antibody titers, by an independent Data Safety and Monitoring Board (DSMB), study will be continued. Part 2 of the study will consist of 150 patients with all types of Category III wounds.
