Trial Outcomes & Findings for Drug Use Investigation Of Azithromycin IV For Pneumonia Or Pelvic Inflammatory Disease (Regulatory Post Marketing Commitment Plan) (NCT NCT01671280)

Last Updated: 2017-04-26

Results Overview

A treatment-related adverse event was any untoward medical occurrence attributed to Zithromac Intravenous use (and Zithromac Tablets) in a participant who received Zithromac Intravenous use (and Zithromac Tablets). A treatment-related serious adverse event was a treatment-related adverse event resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; lifethreatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Relatedness to Zithromac Intravenous use (and Zithromac Tablets) was assessed by the physician.

SECONDARY outcome

Timeframe: 29 days

Population: The effectiveness analysis set comprised of participants in the safety analysis set who had effectiveness evaluation of pneumonia (overall evaluation by the physician based upon change in clinical symptoms and laboratory findings) at least once. Participants evaluated as "unassessable" were excluded from the calculation.

Clinical effectiveness rate in participants with pneumonia, which was defined as the percentage of participants who achieved clinical effectiveness over the total number of asssable effectiveness analysis population with pneumonia, was presented along with the corresponding 2-sided 95% CI. Clinical effectiveness of Zithromac Intravenous use (and Zithromac Tablets) was determined by the physician based on clinical symptoms and laboratory findings, and assessed according to the following categories: (1) effective, (2) ineffective, or (3) unassessable.
