Further study details as provided by Abbott:

Primary Outcome Measures:

Time to recovery (defined as the number of days required to return to baseline after initiation of Klacid). Baseline is defined as the symptom status prior to the onset of RTI. Fast recovery is less than or equal to 5 days from start of Klacid therapy. [ Time Frame: 10 days ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Adverse Events: record the number, symptoms and severity of adverse events for Klacid XL. The action taken, outcome and relationship to Klacid XL treatment should be addressed. [ Time Frame: 10 days ] [ Designated as safety issue: Yes ]
Percentage of treatment failure:defined as failure to return to baseline before 10 days or the requirement of new treatments or medications during the first 10 days for persistence or aggravation of symptoms. [ Time Frame: 10 days ] [ Designated as safety issue: No ]
Factors affecting the speed of recovery:identifying variables independently and significantly associated with the speed of recovery. [ Time Frame: 10 days ] [ Designated as safety issue: No ]

Estimated Enrollment:	418
Study Start Date:	January 2011
Estimated Study Completion Date:	May 2012
Estimated Primary Completion Date:	May 2012 (Final data collection date for primary outcome measure)
