Inovio Pharmaceuticals, Inc. announced that the US Food and Drug Administration (FDA) has placed a clinical hold on its proposed phase III clinical programme for VGX-3100. A clinical hold is a notification issued by the FDA to a trial sponsor to delay a proposed clinical trial or suspend an ongoing clinical trial. This study has not yet been initiated and has not enrolled or dosed subjects. Additionally, the hold does not pertain to any of Inovio’s other ongoing clinical studies.
Inovio anticipates receiving a formal letter with complete information from the FDA within 30 days. In its initial communication, the FDA has requested additional data to support the shelf-life of the newly designed and manufactured disposable parts of the Cellectra 5PSP immunotherapy delivery device. Inovio is working diligently with the FDA to address its concerns and anticipates that the requested data will be available before the end of this year. Inovio estimates that the start of the phase III clinical program will be delayed until the first half of 2017 pending resolution of the FDA’s requests.
