Study start date: December 1, 2003
Actual date on which the first participant was enrolled.To evaluate the safety and efficacy of tigecycline in the treatment of subjects with selected serious infections caused by resistant gram-negative bacteria, eg, Acinetobacter baumannii, Enterobacter species, Klebsiella pneumoniae or other resistant gram-negative pathogens, for whom antibiotics have failed or who cannot tolerate other appropriate antimicrobial therapies. The primary efficacy endpoint will be the clinical response.

Protocol
This section provides details of the study plan, including how the study is designed and what the study is measuring.Design Details
115 patients to be enrolled
Total number of participants that the clinical trial aims to recruit.Treatment Study
These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.
Eligibility
Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.Conditions
Criteria
Any sex
Biological sex of participants that are eligible to enroll.Over 18 Years
Range of ages for which participants are eligible to join.Healthy volunteers not allowed
If individuals who are healthy and do not have the condition being studied can participate.Conditions
Pathology
Bacterial Infections and MycosesBacterial InfectionsInfectionsGram-Negative Bacterial Infections
Criteria
3 inclusion criteria required to participate
Male or female subjects aged 18 years or older
Isolation of a resistant gram-negative pathogen, eg, Enterobacter species, Acinetobacter baumannii, Klebsiella pneumoniae, or other resistant gram-negative pathogens, alone or as 1 isolate of a polymicrobial infection
Resistant gram-negative organisms are defined by the likely presence of ESBL or related mechanisms which limit the therapeutic alternatives for the treatment of complicated infections
3 exclusion criteria prevent from participating
Subjects with any concomitant condition or taking any concomitant medication that, in the opinion of the investigator, could preclude an evaluation of a response or make it unlikely that the contemplated course of therapy or follow-up assessment will be completed or that will substantially increase the risk associated with the subject's participation in this study
Anticipated length of antibiotic therapy < 7 days
Known or suspected hypersensitivity to tigecycline or other compounds related to this class of antibacterial agents (eg, tetracyclines, minocycline, doxycycline)
