Schering-Plough Corporation Release: AVELOX(R) Monotherapy As Effective As High-Dose Levofloxacin And Ceftriaxone Combination Therapy In Treating Patients With Severe Community-Acquired Pneumonia

KENILWORTH, N.J., April 7 /PRNewswire-FirstCall/ -- AVELOX(R) (moxifloxacin HCl) monotherapy at 400 mg once daily is as effective as the high-dose combination of levofloxacin (500 mg twice daily) plus ceftriaxone (2 g once daily) in treating patients with severe community-acquired pneumonia (CAP) requiring hospitalization, according to results of a new clinical study presented at the 16th European Congress of Clinical Microbiology and Infectious Diseases (ECCMID) in Nice, France.

Known as the MOTIV (Moxifloxacin Treatment Intravenous) study, the head- to-head comparison of once-daily AVELOX monotherapy to a combination of high- dose levofloxacin plus high-dose ceftriaxone showed no significant difference in clinical cure rates (4-14 days after the last dose), the primary efficacy endpoint for the two per protocol treatment groups (86.9 percent vs. 89.9 percent, respectively), including CAP patients with the most severe pneumonia. The per protocol population consisted of 569 patients. A total of 748 patients were enrolled in the study, of which 738 patients were randomized. Both treatments were well tolerated in the study, with similar adverse event profiles.

“The results of the MOTIV study are important because community-acquired pneumonia is a particular concern for people with chronic illnesses or impaired immune systems, and is a common cause of hospitalization worldwide,” said Antoni Torres, M.D., professor of pulmonology at the University of Barcelona in Spain. “CAP can critically affect older patients who may be struggling with existing conditions such as heart disease and diabetes,” he added. “These results provide additional evidence that AVELOX is a safe and effective treatment for patients with CAP.”

CAP affects approximately 5.6 million adults in the United States each year, with elderly patients (age 65 and above) 60 percent more likely than the general population to develop the infection.(1,2)

AVELOX, a broad-spectrum fluoroquinolone antibiotic, has been shown to be safe and effective as monotherapy in treating patients with CAP and is approved for this indication. (See About AVELOX section below for more information.)

Study Design

The MOTIV study was a prospective, randomized, multicenter, multinational, double-blind, double-dummy comparative study conducted outside the United States designed to determine the efficacy and safety of AVELOX versus a combination of high-dose levofloxacin and high-dose ceftriaxone in treating severe CAP requiring hospitalization and parenteral treatment (treatment by injection). The high-dose of levofloxacin as well as the combination therapy used in the study are not approved in the United States.

Patients in the study were randomized to receive either: AVELOX I.V./oral 400 mg once daily for seven to 14 days; or the combination of ceftriaxone I.V. 2 g once daily plus levofloxacin I.V. 500 mg twice daily, followed by levofloxacin oral 500 mg twice daily, for seven to 14 days. The dose of levofloxacin could be adjusted according to the patient’s renal function. Patients in the study were stratified by the Pneumonia Severity Index, with 59.1 percent of the 569 patients in the per protocol population classified as having severe pneumonia (PSI Classes IV-V).

About Community-Acquired Pneumonia (CAP)

Community-acquired pneumonia affects 5.6 million adults in the United States annually, resulting in nearly two million cases of hospitalization.(3,4) It is the fifth leading cause of death among people older than 65 years, and a larger percentage of these patients have frequent co-morbidities and require hospitalization and longer hospital and intensive care unit (ICU) stays.(5,6) The cost of treating CAP patients is estimated at $10 billion per year, with 92 percent of those costs spent on hospitalized care.(7) Community-acquired pneumonia is a particular concern for seniors and people with chronic illnesses or impaired immune systems, although it also affects young and healthy people.
