Primary Outcome Measures:
  • Evaluate clinical cure rates of telithromycin over azithromycin for treating adult outpatients with mild to moderate community-acquired pneumonia (CAP) in high pneumococcal bacterial resistance areas, at the test of cure visit (Days 17-21).

Secondary Outcome Measures:
  • To compare the effect of telithromycin versus azithromycin on clinical efficacy in CAP adult outpatients at the end of therapy [ Designated as safety issue: No ]

Enrollment: 110

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
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.
