Criteria

Inclusion Criteria:

Male or female outpatients aged 20 or greater.

• Subjects with a positive Binax NOW S. pneumoniae Urinary Antigen Test and/or positive gram stain for diplococci.

• Subjects with ≤ 7 days of signs and symptoms of CAP.

• Subjects with chest x-ray findings that support a diagnosis of acute pneumonia with presence of a new infiltrate. For subjects with history of chronic obstructive pulmonary disease (COPD), a comparison to previous chest x-ray report is required to confirm the finding of new infiltrates.

Subjects with diagnosis of acute mild to moderate CAP based on at least one of the following:

• fever (oral >37.5°C/99.5°F or axillary >37.4°C/99.4°F or rectal >38.5°C/101.5°F) or

• elevated total peripheral white blood cell count >10,000/mm3 or >15% immature neutrophils (bands), regardless of total peripheral white count and

• new and sudden onset (equal or less than 48 hours) of at least two of the following signs or symptoms:

• cough

• dyspnea or tachypnea (particularly if progressive in nature)

• pleuritic chest pain

• purulent sputum production or change in sputum character

• auscultatory findings (such as rales and/or evidence of pulmonary consolidation)

Exclusion Criteria:

• Subjects presenting with any of the following will not be included in the study.

• Subjects with CAP requiring hospitalization.

• Subjects with signs and symptoms of severe CAP lasting greater than 7 days.

• Subjects requiring parenteral antibiotic treatment.

• Subjects discharged from hospital within the 10 days before study entry.

• Subjects with visible/gross aspiration pneumonia.

• Subjects with any concomitant pulmonary disease, condition or complication that could confound the interpretation or evaluation of drug efficacy or safety, including:

• severe bronchiectasis, cystic fibrosis or suspected active pulmonary tuberculosis

• suspected acute pulmonary embolism

• emphysema, lung abscess, extra pulmonary extension (e.g., meningitis, septic arthritis, endocarditis)

• known bronchial obstruction or a history of postobstructive pneumonia.

• Subjects with neoplastic lung disease (lung cancer) or another malignancy metastatic to the lungs, and/or requiring chemotherapeutic interventions for this or other neoplasms.

• Subjects with infection requiring administration of other systemic antimicrobial agents.

• Subjects with progressively fatal disease; life expectancy ≤3 months.

• Subjects with myasthenia gravis.

• Subjects with any concomitant condition, including severe and/or uncontrolled cardiovascular, neurologic, endocrine, or other severe and/or uncontrolled major systemic disease that make implementation of the protocol or interpretation of the study results difficult.

• Immunocompromised subjects, such as:

• known HIV subjects with CD4+ T-lymphocyte count dated less than 3 months <200/mm3 and /or HIV subjects treated with isoniazide or clarithromycin as prophylaxis

• neutropenia (<1500 neutrophils/mm3) not attributable to the acute infectious disease

• metastatic or hematological malignancy

• splenectomy or known hyposplenia or asplenia

• chronic corticosteroid therapy.

• Subjects with a history of congenital or a family history of long QT syndrome (if not excluded by previous ECG) and subjects with known acquired QT interval prolongation

• Known severe impaired renal function as shown by creatinine clearance < 30 ml/min either measured or estimated with Cockroft formula.

• Subjects who have received more than 24 hours of effective treatment with other antibiotics, within the 7 days prior to enrollment in the study.

• Subjects with a known or suspected hypersensitivity to, or a known or suspected serious adverse reaction to telithromycin or any macrolide antibiotic.

• Subjects who will require on-study treatment with medications known to have potential drug interactions, including ergot alkaloids derivatives, terfenadine, astemizole, cisapride, pimozide, simvastatin, atorvastatin and lovastatin (see Section 6.2).

• Subjects who have received any investigational drug within 1 month prior to study entry or such treatment is planned for during the study period.

• Subjects who are pregnant or breast-feeding.

• Subjects with recent drug or alcohol abuse.Subjects with a mental condition rendering the subject unable to understand the nature, scope, and possible consequences of the study.

• Subject is the investigator or any subinvestigator, research assistance, pharmacist, study coordinator, other staff or relative thereof directly involved in the conduct of the protocol.

• Subjects already enrolled in this study.
