Nasal Decolonization of Staphylococcus Aureus Clinical Trial
Official title:
A Phase IIa, Randomised, Double-blind, Placebo-controlled Study to Evaluate the Efficacy, Safety and Tolerability of 3% LTX-109 Compared to Placebo for Nasal Decolonisation of Staphylococcus Aureus.
A Phase IIa, double-blind, placebo-controlled, randomised study designed to evaluate the efficacy, safety and tolerability of two dosing regimens with LTX-109 administered topically to the anterior nares in subjects with persistent carriage of Staphylococcus aureus (S. aureus).
Approximately 90 subjects planned screened to achieve 27 randomised and dosed subjects with persistent S. aureus carriage. On Day 1, subject randomisation in a 2:1 ratio to receive either LTX-109 (n=18) or placebo (n=9). Cohort (1 [8 doses] or 2 [6 doses]) used as a stratification variable to preserve the 2:1 treatment randomisation ratio in each cohort (LTX-109 n=9 or placebo n=5/4). For all subjects, the IMP was to be applied 4 times during an intensive dosing regimen for 4 ½-hours (on Day 1 at 0, 1 ½, 3 and 4 ½ - hours). For subjects in Cohort 1, this was followed by 4 additional applications: on Day 1 at 12 hours, on Day 2 at 24 and 36 hours, and on Day 3 at 48 hours. For subjects in Cohort 2 the IMP was likewise applied 4 times during the 4 ½-hour period (on Day 1 at 0, 1 ½, 3 and 4½ hours), but was followed by 2 applications: on Day 1 at 12 hours and on Day 2 at 36 hours. On each dosing occasion, a large drop (approximately 250 μL) of IMP was applied into each nostril and distributed to cover the whole area of the nostril. The subjects were carefully monitored by clinical staff during and after dosing. Safety assessments (AEs, vital signs, safety laboratory assessments and local tolerability) and efficacy assessments (nasal swab) were performed. All subjects were instructed to wash the body and hair with chlorhexidine body wash and shampoo at the CRU on Day 1 (prior to the first dose) and on Day 2. Subjects were provided with chlorhexidine body wash and shampoo for body and hair wash at home on Day 3, Day 4, Day 5, Day 6 and Day 7. On Day 3 and Day 7, subjects used the chlorhexidine shower before the visits to the CRU. A final end-of-study visit (Visit 5) took place on Day 7 (+2 days) or after early withdrawal. ;
