7 Clinical Trials for Various Conditions
This is a multicenter,randomized,double-blind, placebo-controlled, phase 2 study designed to evaluate the safety, tolerability and efficacy of a continuous rate infusion (CRI) of IV varespladib followed by transition to the oral dosage form, varespladib-methyl, concurrently with SOC, in participants bitten by venomous snakes.

This is a multicenter, randomized, double-blind, placebo-controlled, phase 2 study designed to evaluate the safety, tolerability and efficacy of varespladib-methyl, concurrently with standard of care (SOC), in subjects bitten by venomous snakes.
Early identification of tissue injury from a rattlesnake bite is critical to prevent complications and reduce health care costs. Given the limitations of clinical assessment, there is a need to develop a more objective reproducible, anatomically detailed diagnostic tool for to accurately assess tissue damage and assist with timely administration of antivenom, if needed. Emergency physician performed point-of-care ultrasonography has been shown to be beneficial in the diagnosis and management of skin and soft tissue infections. The innovative use of bedside ultrasound technology can provide new information to individualize antivenom treatment and to improve patient outcomes. The objectives of this study is to compare clinical assessment and bedside ultrasound findings in the detection of tissue injury in emergency department patients with rattle snakebite and determine if bedside ultrasound can alter management (antivenom dosing) in emergency department patients with rattle snakebite.
This research is intended to show that it is safe and not difficult for nearly anyone to inject at least 125ml of a dilute solution of tumescent lidocaine and epinephrine (TLE), where a TLE solution consists of lidocaine (1gm/L) and epinephrine (1mg/L) in normal saline.
The purpose of this study is to see whether a new F(ab')2 antivenom will prevent injury and death from the bite of a coral snake. Funding Source - FDA OOPD.
This phase II study was a prospective, randomized, open-label, multi-center study in the United States, involving patients from 18 to 70 years of age, comparing Anavip (Antivenin Crotalinae \[pit viper\] equine immune F(ab)2; Instituto Bioclon, Mexico City, Mexico) against CroFab (Protherics Inc., Nashville, Tennessee), the only currently approved product for treatment of Crotalinae (pit viper) envenomation in the US. The study was designed to evaluate the hypothesis that lasting correction of snakebite induced thrombocytopenia and hypofibrinogenemia are possible following correction with F(ab)2 antivenom, by analyzing in detail the relationships among platelet count, fibrinogen, venom levels, and antivenom levels in subjects presenting with thrombocytopenia following crotaline viper envenomation. In the study we expected to see a fall in platelet count following Fab treatment, commensurate with that reported in the past. We hypothesized that following F(ab)2 treatment there would be a slower drop in post-treatment platelet counts, with a relatively higher platelet count at any given point in the follow-up period. We further hypothesized that an initial rise and later fall in platelet count would correspond with rise and fall in antivenom levels, and would be mirrored by concurrent drop and rise in levels of unbound circulating venom.
The purpose of this study is to establish if F(ab)2 antivenom (Anavip) is safe for crotalinae envenomation. Confirm its effectiveness in preventing the occurrence of delayed coagulopathies and compare the safety and efficacy with Fab antivenom (CroFab) in patients with Crotalinae envenomation.
