Official Title: “A Multicenter, Open Label Trial Evaluating Intravenous Azithromycin Plus Intravenous Ampicillin/Sulbactam Followed by Oral Azithromycin Plus Intravenous Ampicillin/Sulbactam for the Treatment of Hospitalized Subjects With Community-Acquired Pneumonia (CAP)”

The intravenous (IV) regimen containing azithromycin (Zithromax) plus ampicillin-sulbactam is consistent with current guidelines for the treatment of CAP. In fact the International guidelines for the treatment of CAP in hospitalised patients suggests the use of a combination between a b-lactam and a macrolide.

This trial will allow investigators to evaluate the efficacy of azithromycin plus ampicillin-sulbactam in the treatment of hospitalized subjects with community acquired pneumonia. In addition, this trial will allow investigators to evaluate the safety and toleration of combination therapy.

Study Type: Interventional

Study Design: Treatment, Non-Randomized, Open Label, Uncontrolled, Single Group Assignment, Efficacy Study

Intervention(s) in this Clinical Trial

• Drug: Azithromycin
• Drug: Ampicillin/sulbactam

Primary Measures

• To evaluate the clinical efficacy of intravenous (IV) azithromycin 500 mg once daily plus IV ampicillin/sulbactam 3 grams twice a day (BID) for 2 to 5 days
• followed by oral azithromycin 500 mg once daily plus IV ampicillin/sulbactam 3 grams.

Secondary Measures

• To evaluate the eradication of baseline pathogens of IV azithromycin plus IV ampicillin/sulbactam followed by oral azithromycin plus IV ampicillin/sulbactam at Visit 3 and Visit 4

Inclusion Criteria:

• Subjects must require hospitalization and intravenous therapy.
• Subjects must have a Fine pneumonia score > 70 (Fine Class > II).

• new infiltrate(s) on chest X-ray; AND
• at least two of the CAP signs or symptoms.

Exclusion Criteria:

• Significant gastrointestinal or other conditions which may affect study drug absorption; and
• Significant cardiovascular disorders.
• Immunosuppressive therapy, defined as chronic treatment with known immunosuppressant medications
• Impaired hepatic function, as shown by, but not limited to, AST, (SGOT), or ALT (SGPT) greater than three times the laboratory upper limit of normal, or total bilirubin greater than two times the upper limit of normal.
• Subjects already hospitalized or who resided in a long-term-care facility for greater than 14 days before the onset of symptoms.
