Phase III Study Comparing GR2001 Injection and Human Tetanus Immunoglobulin for Prevention of Tetanus

What this Trial Is About

Researchers are comparing the safety and effectiveness of a new injection called GR2001 with Human Tetanus Immunoglobulin HTIG for preventing tetanus. This Phase III clinical trial focuses on adults who may have been exposed to tetanus through dirty or contaminated wounds. The study aims to see how well GR2001 works in raising protective antibody levels against tetanus. Participants will be randomly assigned to receive a single intramuscular injection of either GR2001 or HTIG in the gluteal muscle on the first day of the study. GR2001 is provided in a 5mg1ml vial with specific packaging materials, while HTIG is a licensed human plasma-derived immunoglobulin. Both treatments are given once, and the study is designed as a double-blind trial. During the trial, researchers will monitor the increase in anti-tetanus antibody levels up to 12 hours after injection and follow participants for up to 105 days to observe the occurrence of tetanus and assess safety. They will also evaluate how GR2001 behaves in the body, including its peak concentration and overall exposure. Participants will undergo assessments and safety monitoring throughout this period to gather comprehensive data on the treatment effects.
