FDA rejects Replidyne’s faropenem Louisville firm drug rejected; considered “nonapprovable’ 10/24/06 The US Food and Drug Administration (FDA) refused to approve faropenem, an antibiotic manufactured by Louisville-based Replidyne. The FDA said the drug was “nonapprovable,” but did not refer to specific safety concerns about the product.The company will have to conduct new studies and clinical trials, lasting an estimated two more years, to prove the drug treats community-acquired pneumonia, bacterial sinusitis, chronic bronchitis and skin infections.

Faropenem(106560-14-9) has yet to receive marketing approval in the United States, and was submitted for consideration by the United States Food and Drug Administration (FDA) on 20 December 2005. The new drug application (NDA) dossier submitted included four proposed indications:

• acute bacterial sinusitis
• community acquired pneumonia
• acute exacerbations of chronic bronchitis
• uncomplicated skin and skin structure infections
