Polarean Imaging Complete Response Letter
FDA has issued a complete response letter declining to approve in its current form a Polarean Imaging NDA for an investigational drug-device combination product using hyperpolarized xenon-129 gas to enhance MRI imaging in pulmonary medicine. The company says the letter was “unexpected” and contained issues that are “mostly technical or manufacturing-related,” centering around the xenon hyperpolarizer system.
“Polarean will work to address the issues identified by FDA with a view to resubmitting the NDA and securing FDA approval as quickly as possible,” the company says.
