Last verified: December 2011
This is a study to evaluate the safety of tigecycline in patients with complicated intra-abdominal infections (cIAI) and complicated skin and soft tissue infections (cSSTI) under real practice in the usual hospital setting and patients' conditions, in order to assess the "real incidence" of adverse events related with tigecycline in these patients.

Condition Intervention
Intra-Abdominal Infections
Skin Disease, Infectious
Soft Tissues Infections
Drug: Tigecycline

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: A Phase IV Pharmacovigilance, Post-Authorization Clinical Trial To Evaluate And Assess The Safety Of Tigecycline In The Approved Indications In The Usual Health Care Setting

Primary Outcome Measures:
  • Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) [ Time Frame: Up to Week 12 ]
    Any untoward medical occurrence in a participant who received study treatment was considered an AE without regard to possibility of causal relationship. An AE resulting in any of the following outcomes, or deemed to be significant for any other reason, was considered to be a SAE: death; initial or prolonged inpatient hospitalization; a life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.

Secondary Outcome Measures:
  • Percentage of Participants With Clinical Response of Cure [ Time Frame: Days 2-5, 7-14 and 21-28 during treatment and Days 1-3 after end of treatment ]
    Cure was defined as complete resolution of infection symptoms and clinical signs of the disease to the extent that no further antibiotic treatment was required, as assessed by the attending physician.

  • Number of Participants With Susceptible Microbiological Pathogens [ Time Frame: Baseline and Week 12 ]
    Evaluation of susceptibility to the tigecycline treatment included: Escherichia coli Extended Spectrum Beta Lactamases (E. coli ESBL); Klebsiella pneumoniae (K. pneumoniae) ESBL; Bacteroides species resistant to clindamycin (RClin); Staphylococcus aureus (S. aureus) methicillin resistant S. aureus (MRSA); vancomycin resistant Enterococcus (VRE) species; Resistant to third generation cephalosporins (RCef3) Enterobacter species; RCef3 Serratia species; Proteus species ESBL; carbapenem resistant (RCarb) Pseudomonas aeruginosa (P. aeruginosa); Acinetobacter baumannii (A. baumannii) RCarb.

  • Number of Participants With Eradication of Microbiological Pathogens [ Time Frame: Week 12 ]
    Evaluation of eradication after treatment with tigecycline included following microbiological pathogens: E. coli ESBL; K. pneumoniae ESBL; Bacteroides species RClin; S. aureus (MRSA); Enterococcus species (VRE); Enterobacter species RCef3; Serratia species RCef3; Proteus species ESBL; P. aeruginosa RCarb; A. baumannii RCarb.

Enrollment: 115
Study Start Date: August 2008
Study Completion Date: December 2010
Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Patients hospitalized because of cIAI or cSSTI
Drug: Tigecycline
Tigecycline 50 or 100 mg intravenously. Therapy conducted according to the package leaflet of Tygacil and to international treatment guidelines. Tygacil will be dosed according to labeling. The administration and duration of the therapy will be determined by the treating physician to meet the patient individual needs for treatment.
Other Name: Tygacil

Detailed Description:
Since around 50 patients were included in Spanish centers involved in the Phase III Tygacil clinical development program, and on the basis of the recruitment capacity of the centers within the predefined time window and the number of patients consenting to be enrolled in the study, the total number of patients estimated to be enrolled in the study is 500. With this sample size, it will be possible to obtain precise estimations of the incidence of particular types of adverse events.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
Patients hospitalized because of complicated intra-abdominal infections (cIAI) or complicated skin and soft tissue infections (cSSTI), in the usual health care setting

Inclusion Criteria:
