What is the current status of clinical trials for Tigecycline?
Tigecycline, a glycylcycline antibiotic sold under the brand name Tygacil, has undergone multiple clinical evaluations predominantly for complicated skin and intra-abdominal infections and community-acquired pneumonia. The most recent phase trials focus on exploring its efficacy against multi-drug resistant organisms, including carbapenem-resistant bacteria.
Ongoing and Recent Clinical Trials
- Phase III Trials: The last registered pivotal Phase III trial (NCT02851882) ended in 2019, comparing Tigecycline with comparator antibiotics for complicated intra-abdominal infections. Results indicated non-inferiority but highlighted adverse effects such as nausea and vomiting.
- Phase IV/Post-Marketing Surveillance: Confirmed safety profile with continued monitoring for off-label uses and resistance patterns, particularly in Southeast Asia and Africa.
- Emerging Trials:
- Investigations into combination therapies against resistant pathogens like Acinetobacter baumannii.
- Trials assessing alternative formulations, including intravenous and intraperitoneal delivery.
- Regulatory Status: Approved by FDA (2005), EMA (2006), but with warnings about increased mortality risk, limiting its use to specific indications.
