About this study
This prospective, comparative study is evaluating the effectiveness and adverse effects of using colistin at a loading dose of 9 million international units (MIU) followed by 4.5 MIU every 12 h (q12 h) + tigecycline at a loading dose of 100 mg followed by 50 mg every 12 h (q12 h) versus colistin + meropenem 2 g q8 h in treating blood stream infections due to multidrug-resistant (MDR) Klebsiella pneumoniae. The aims of the current study are to investigate and evaluate the therapeutic activity and side effects of Colistin-Meropenem combined therapy versus Colistin-Tigecycline combined therapy in treatment of patients with Multiple Drug Resistant (MDR)-Klebsiella pneumonia bacteraemia The primary goal is comparing 14 day mortality between critically ill patients with MDR Gram-negative Klebsiella pneumoniae infection as evaluation of the therapeutic activity of colistin - tigecycline vs. colistin - meropenem combined therapies. The secondary goal is comparing the comorbidities (nephrotoxicity, hepatotoxicity, neurotoxicity, hematological changes) between critically ill patients with MDR Gram-negative Klebsiella pneumoniae infection who will be treated with colistin - tigecycline versus colistin - meropenem combined therapies.
Method: A total of 60 patients were divided into two groups (30 patients each); the first group received Intravenous colistin 9 MIU IV infusion over 2 hours loading dose followed by maintenance dose 4.5 MIU IV infusion over 2 hours q12 h plus Intravenous Tigecycline 100 mg IV infusion over 1 hour loading dose followed by maintenance dose 50 mg IV infusion over 1 hour q12 and the second group received Intravenous colistin 9 MIU IV infusion over 2 hours loading dose followed by maintenance dose 4.5 MIU IV infusion over 2 hours q12 h plus Intravenous meropenem 2 g IV infusion over 30 minutes q8 h

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Colistin, Meropenem and Tigecycline in people with Treatment of Blood Stream Infections Due to Multidrug-Resistant Klebsiella Pneumoniae, run by Al-Azhar University at 1 site in Egypt.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 29 Jul 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Salma Wagih Abdalla, Bachelor (00201100701178, salma9793@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Comparing 14 day mortality between critically ill patients with MDR Gram-negative Klebsiella pneumoniae infection as evaluation of the therapeutic activity of colistin - tigecycline vs. colistin - meropenem combined therapies. (time frame: 7-14 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04489459, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jul 2020.
