Clinical Trials and Efficacy of Noxafil (Posaconazole)
Overview of Noxafil
Noxafil, also known as posaconazole, is a potent triazole antifungal agent developed by Schering-Plough Corporation. It is indicated for the treatment and prophylaxis of various serious fungal infections, including invasive aspergillosis, fusariosis, chromoblastomycosis, mycetoma, and coccidioidomycosis, among others[3][4].
Key Clinical Trial Findings
A significant clinical study presented at the Trends in Medical Mycology (TIMM 2005) meeting highlighted the efficacy of Noxafil in preventing invasive fungal infections (IFIs) in allogeneic hematopoietic stem cell transplant (HSCT) recipients with graft-versus-host disease (GVHD). Here are the key findings:
- Reduction in Invasive Fungal Infections: Noxafil significantly reduced the incidence of aspergillosis and overall IFIs compared to fluconazole. Specifically, Noxafil reduced aspergillosis cases from 17 to 3 and overall IFIs from 22 to 7 during the treatment period[1].
- Mortality Reduction: The study showed that Noxafil decreased deaths attributed to IFIs, with 4 deaths in the Noxafil group versus 12 in the fluconazole group[1].
- Safety Profile: Both Noxafil and fluconazole demonstrated a similar safety profile, with both drugs being well tolerated by the patients[1].
