A Phase I/IIa Study to Evaluate the Safety, Tolerability and Efficacy of Topical LTX-109 in Subjects Nasally Colonized With Methicillin-resistant/-Sensitive Staphylococcus Aureus (MRSA/MSSA)
|ClinicalTrials.gov Identifier: NCT01158235|
Recruitment Status : Completed
First Posted : July 8, 2010
Last Update Posted : June 8, 2011
This is a pilot study conducted to evaluate the safety, local tolerability and efficacy of LTX-109(Lytixar™), a lytic peptide designed to kill bacterias quickly and efficient. LTX-109 (Lytixar™)will be applied in the anterior nares in subjects who are carriers of nasal colonies of MRSA/MSSA.
The extent of systemic absorption of LTX -109 when applied to the anterior nares will be evaluated and the effect of Lytixar™ as to clear colonies of MRSA/MSSA during the the observation period and Week 2 to Week 9 after treatment.

- Local tolerability in the anterior nares [ Time Frame: Day 1, 2, 3. week 2-9 after final treatment. ]To explore safety, local tolerability and efficacy of LTX-109 when applied topically into the anterior nares in subjects with nasal colonisation of MRSA/MSSA. To determine the extent of systemic absorption of LTX -109 when applied to the anterior nares.
- To evaluate recurrence of MRSA/MSSA during the observation period. [ Time Frame: Week 2 to Week 9 after treatment. ]
