3 Clinical Trials for Various Conditions
This study will evaluate the recovery from copperhead snake bite in patients with mild or moderate venom effect. Potential subjects received CroFab antivenom or placebo. After blinded treatment and discharge, the subject returns to the clinic for follow-up assessments at day 3, 7, 14, and 28 after snake bite as well as follow-up telephone assessments on day 10, 17, and 24 after snake bite. The purpose of this study is to compare recovery in copperhead snake bite patients treated with antivenom vs placebo (no active drug) as measured by the Patient Specific Functional Scale (PSFS) at Day 14 follow-up. The primary efficacy endpoint of this study was achieved.
Most patients bitten by copperhead snakes do not currently receive antivenom. Some snakebite victims have long term problems with the function of the limb that was bitten. This study will determine whether early administration of antivenom to patients with mild to moderate copperhead snakebites reduces long-term complications.
The primary objective of the study is to evaluate the responsiveness and utility of several clinical outcome assessments in the setting of copperhead snakebite. The secondary objective is to characterize the clinical course of signs, symptoms and impairment during the recovery phase of copperhead snakebite.
