Safety and Immunogenicity Study of Recombinant Thrombin (rThrombin) in Pediatric Participants

25 de enero de 2012 actualizado por: ZymoGenetics

A Phase 4, Open-Label, Single-Group Safety and Immunogenicity Study of RECOTHROM® (rThrombin) in Pediatric Subjects Undergoing Synchronous Burn Wound Excision and Skin Grafting

The objective of this study is to assess the safety and immunogenicity of recombinant thrombin (rThrombin) administered as an aid to hemostasis during burn wound excision and skin grafting in pediatric patients, newborn through 17 years of age.

Descripción detallada

The safety, immunogenicity, and efficacy of rThrombin have been evaluated in 5 Phase 2 studies, 1 pivotal Phase 3 study, and 1 Phase 3b study, in surgical indications such as: spinal surgery, major hepatic resection, peripheral arterial bypass surgery, arteriovenous graft formation for hemodialysis access, and burn wound excision. Limited data currently exist on the effects of rThrombin exposure in pediatric patients. This Phase 4 trial aims to provide additional information on the use of rThrombin in children by evaluating the drug's safety and immunogenicity when administered as an aid to hemostasis during burn wound excision and skin grafting in pediatric burn patients.

¿Qué mide el estudio?

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Number of Participants With Death, Serious Adverse Events, Treatment-related Adverse Events (AE), AEs Leading to Discontinuation, and AEs of Hypersensitivity
Periodo de tiempo: Days 1 through 29, continuously
An AE is any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that does not necessarily have a causal relationship with treatment. An SAE is any unfavorable medical event that at any dose results in death, persistent or significant disability/incapacity, or drug dependency or abuse; is life-threatening, an important medical event, or a congenital anomaly/birth defect; or requires or prolongs hospitalization. Treatment-related=possibly, probably, or certainly related to and of unknown relationship to study treatment
Days 1 through 29, continuously
Number of Participants With AEs by Maximum Severity
Periodo de tiempo: Days 1 through 29, continuously
An AE is any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that does not necessarily have a causal relationship with treatment. Mild=asymptomatic or minor symptoms; intervention not indicated. Moderate=requiring only minimal, local, or noninvasive intervention. Severe=significant symptoms but not life-threatening; hospitalization or invasive intervention indicated. Life-threatening=indicating intensive care or urgent invasive intervention.
Days 1 through 29, continuously
Number of Participants With Clinical Laboratory Findings of Grade O or Higher in Platelet, White Blood Cell (WBC), Lymphocyte, and Neutrophil Counts
Periodo de tiempo: Baseline and Day 29 from Baseline
Abnormal laboratory findings were recorded as AEs when considered clinically significant (unusual for the surgical population or individual participant) by the investigator, when associated with symptoms, when requiring specific treatment, or when requiring a change in participant management.LLN=lower level of normal. Platelets: Grade 0=normal. WBC: Grade 0=normal. Lymphocytes: Grade 0=normal; Grade 1=<LLN x 0.8-10^9/L. Neutrophils: Grade 0=normal; Grade 1=<LLN-1.5x10^9/L; Grade 2=<1.5-1.0x10^9/L
Baseline and Day 29 from Baseline
Number of Participants With Clinical Laboratory Findings of Grade 0 or Higher in Hemoglobin Levels
Periodo de tiempo: Baseline and Day 29 from Baseline
LLN=lower level of normal. Grade 1=100 g/L to <LLN; Grade 2=80 to <100 g/L; Grade 3=65 to <80 g/L; Grade 4=<65 g/L.
Baseline and Day 29 from Baseline
Number of Participants With Clinical Laboratory Findings of Grade 0 or Higher in Creatinine Levels
Periodo de tiempo: Baseline and Day 29 from Baseline
ULN=upper level of normal. Grade 0=normal; Grade 1=>ULN to 1.5 x ULN.
Baseline and Day 29 from Baseline
Number of Participants With Elevations in the Coagulation Parameter of Activated Partial Thromboplastin Time (aPPT)of Grade 0 or Higher
Periodo de tiempo: Baseline and Day 29 from Baseline
ULN=upper limit of normal. Grade 0=normal; Grade 1=ULN to 1.5 x ULN.
Baseline and Day 29 from Baseline
Number of Participants With a High International Normalized Ratio (INR) of Prothrombin Time of Grade 0 or Higher
Periodo de tiempo: Baseline and Day 29 from Baseline
Grade 0=normal.
Baseline and Day 29 from Baseline

Medidas de resultado secundarias

Medida de resultado
