Safety and Efficacy Study of Oxazolidinone to Treat Pneumonia
Community-Acquired Pneumonia (CAP)
About this trial
This is an interventional treatment trial for Community-Acquired Pneumonia (CAP)
Eligibility Criteria
Inclusion Criteria:
- Adult patients with mild to moderate CAP.
- Adult men and women ≥18 years.
- Females must be post-menopausal for at least 1 year or surgically sterile (hysterectomy or tubal ligation).
- Sexually active males must use a barrier method of birth control during and for 30 days after the study. Their female partner should also use an additional reliable method of contraception during and for 30 days after the study.
- The patient must present with an acute respiratory illness (≤7 days duration) with which history and physical examination is consistent with a diagnosis of CAP.
Patients requiring immediate study drug therapy before serology or culture results are known may be entered with a presumptive diagnosis of CAP based on:
A chest radiograph at baseline, which shows a new infiltrate(s) consistent with pneumonia as interpreted by the radiologist or the investigator and subsequently confirmed by the radiologist.
AND at least 2 of the following signs and symptoms:
New or increased cough. Purulent sputum or change in sputum character. Auscultatory findings consistent with pneumonia. New onset or progressive dyspnea or tachypnea. Fever >38ºC oral or >38.5ºC tympanic. White blood cell (WBC) count greater than 10,000 cells/mm3 or >15% immature neutrophils (bands), regardless of total peripheral WBC count, or less than 4,500 cells/mm3.
Patient must be able to swallow large capsules intact.
A written, voluntarily signed informed consent must be obtained from the patient prior to the initiation of any study-related procedures.
Exclusion Criteria:
- Hypersensitivity to linezolid.
- Patients are excluded if they have taken oral or parenteral antibiotics as follows:
long-acting penicillin within 28 days of enrollment azithromycin, ceftriaxone, or telithromycin within 14 days prior to enrollment any other antibiotics for >24 hours within 3 days of enrollment
- Require parenteral antibiotics for the treatment for CAP.
- Patient should not have been hospitalized or resided in a long-term facility for at least 14 days before the onset of symptoms.
- Evidence of other pulmonary disease that precluded evaluation of therapeutic response. Patients with known bronchial obstruction or a history of postobstructive pneumonia. (This does not exclude patients who have chronic obstructive pulmonary disease).
- Experienced a recent clinically significant coagulopathy.
- History of cystic fibrosis, active tuberculosis, meningitis, endocarditis, or osteomyelitis.
- Immunocompromised patients including, but not limited to patients with a CD4+ cell count of <350 cells/mm3 secondary to human immunodeficiency virus (HIV) infection, neutropenic patients with granulocytes <1000/mm3 or immunosuppression secondary to drugs such as corticosteroid therapy (>10 mg/day of prednisone or equivalent for at least the past 3 months), splenectomized patients or patients with known hyposplenia or asplenia.
- Patients who have severe liver disease.
- Treatment with an investigational drug within 4 weeks prior to study drug administration.
- Any underlying condition or disease state that would interfere with the completion of the study procedures and evaluation of the absorption of study drug.
- Patients with bronchiectasis and a history of recent respiratory infection caused by Pseudomonas aeruginosa.
- Any infection which requires the use of a concomitant antimicrobial agent, in addition to study drug.
- Patients taking serotonergic agents, selective serotonin reuptake inhibitors (SSRIs) or monoamine oxidase inhibitors (MAOIs).
