Filter by:The purpose of the Registry was to evaluate patient safety following Botulism Antitoxin Heptavalent (A, B, C, D, E, F, G) - (Equine) (BAT®) administration in adult and pediatric patients with a confirmed or suspected exposure to botulinum toxin.
The purpose of this study is to verify the pediatric dosing recommendations for BAT product in pediatric patients that are treated with BAT product due to a confirmed or suspected case of botulism. A minimum of one serum sample should be collected but whenever feasible additional serum samples (up to three per enrolled participant) may be collected from the participant or obtained from surplus standard of care samples, if available, within 32 hours after BAT product administration. Safety of the BAT product will also be evaluated. Emergent will follow-up with the physician by telephone after 30 days post-BAT product administration to collect AEs, SAEs, and unanticipated events.
This Phase 3 clinical trial is a double blind, placebo-controlled, randomized, multicenter investigation of rBV A/B in male and female healthy adults 18 to 55 years of age.
Study rBV A/B-CL-001 is a Phase 2b, 2-part, open-label, uncontrolled study to evaluate safety, tolerability, and immunogenicity of a single dose of recombinant botulinum vaccine A/B (rBV A/B) for the production of BabyBIG in volunteers previously immunized with the pentavalent botulinum (PBT) toxoid. This study is designed to determine neutralizing antibody levels for botulinum toxin types A and B in healthy subjects who were previously immunized with the PBT for occupational protection and who receive the rBV A/B. Subjects with titers of the neutralizing antibodies against the toxins would be candidates for plasma donation for BabyBIG production.
Main objectives: Evaluate the effectiveness of an administration of 3,4-diaminopyridine (FIRDAPSE ®) in severe botulinic poisoning in measuring the effect on electrophysiological and respiratory parameters Secondary Objective: Study the natural history of electrophysiological and respiratory parameters during the botulinic intoxication Primary endpoint: Clinical, electrophysiological and respiratory before and after administration of 3,4-diaminopyridine. Study Design: Pilot study, prospective, interventional. Study population: Case series (n = 8 patients) suffering from botulinic type A, respiratory failure, but with no other organ failure Experimental treatment : 3,4-diaminopyridine, FIRDAPSE ® (BioMarin) The dosage will be gradually increased according to a predetermined scheme and will not exceed 60 mg / day and 20 mg / dose. Statistics: Intra-individual comparison of physiological parameters measured before and after administration of 3,4-diaminopyridine. Electromyographic and respiratory parameters will be measured for each patient. Then a dose of 10 mg of 3,4-diaminopyridine will be administrated. If this dose is well tolerated and provides a relative improvement of 10% for at least one of the parameters studied, the dose will be maintained at 10 mg for 48 hours 3 times a day then increased to 20 mg. The primary endpoint is the change in the amplitude of muscle response evaluated by the subtraction of amplitude at T1.5 and T0.
This is a phase I, single-center, placebo-controlled, double-blinded, dose escalation study of anti-botulinum toxin monoclonal antibodies in healthy adult volunteers. Volunteers will be hospitalized in the Johns Hopkins Phase 1 unit during the infusion and until after the 24-hour blood draw. Three escalating dose cohorts of a combination of three anti-botulinum monoclonal antibodies will be evaluated. Each cohort will consist of eight volunteers in which they will receive a single intravenous infusion of active drug or placebo. Placebo will be normal saline. Volunteers will be followed for safety for up to 120 days after infusion depending on dose cohort.
The primary purpose of this study is: 1. To evaluate the model determined by the ability of botulism antitoxin (bivalent, Aventis) to neutralize Botulinum toxin in the Extensor Digitorum Brevis model of muscle paralysis in Stage A. 2. To assess the ability of botulism antitoxin (heptavalent, Cangene) to neutralize Botulinum toxin in the Extensor Digitorum Brevis model of muscle paralysis in Stage B.
A second botulism outbreak in Northern Thailand was reported in 2006. 192 people were exposed to raw meat and the gut of deer, 83 suffered from diarrhea. Of these 5 developed respiratory failure, 1 impending respiratory failure. We analysed the clinical findings and electrophysiologic findings in this second episode of large botulism outbreak in northern Thailand.
Background. Northern Thailand's biggest botulism outbreak to date occurred on 14 March 2006 and affected 209 people. Of these, 42 developed respiratory failure, and 25 of those who developed respiratory failure were referred to 9 high facility hospitals for treatment of severe respiratory failure and autonomic nervous system involvement. Among these patients, we aimed to assess the relationship between the rate of ventilator dependence and the occurrence of treatment by day 4 versus day 6 after exposure to bamboo shoots (the source of the botulism outbreak), as well as the relationship between ventilator dependence and negative inspiratory pressure. Methods. The investigators reviewed the circumstances and timing of symptoms following exposure. Mobile teams treated patients with botulinum antitoxin on day 4 or day 6 after exposure in Nan Hospital (Nan, Thailand). Eighteen patients (in 7 high facility hospitals) with severe respiratory failure received a low- and high-rate repetitive nerve stimulation test, and negative inspiratory pressure was measured.
OBJECTIVES: I. Determine the safety of human botulism immune globulin (BIG) in patients with infant botulism by monitoring side effects (e.g., rash, fever, hypotension, and anaphylaxis). II. Assess the efficacy of BIG in these patients by monitoring disease severity, incidence of complications (respiratory arrest, aspiration, pneumonia, etc.), and length of hospital stay.
