FDA provides Celsion guidance for Thermodox NDA to treat primary liver cancer

Celsion Corporation (Nasdaq: CLSN), a leading oncology drug development company, announced that the Company has reached agreement with the U.S. Food and Drug Administration (FDA) that the requirements for non-clinical studies have been met for the New Drug Application (NDA) of ThermoDox.  

The FDA has provided written guidance that the Company is not required to conduct any additional non-clinical pharmacology, safety pharmacology and general toxicology studies assuming the results of current studies are adequate.  The results of these current studies will be reviewed at the time of NDA submission.  This agreement takes advantage of an NDA application known as a 505(b)2 which allows a company to reference existing data regarding doxorubicin and other liposomal drugs currently approved by the FDA.  

As previously announced, the FDA has granted Fast Track Development for the Company's 600 patient pivotal Phase III clinical trial (the HEAT study) of its investigational drug, ThermoDox®, in combination with radiofrequency ablation (RFA),  The Fast Track Development Program provides for expedited regulatory review including frequent interactions between the FDA. Celsion is eligible to submit its NDA on a rolling basis and review sections of the NDA with the FDA in advance of submitting the complete submission.  The HEAT study is being conducted under a Special Protocol Assessment (SPA) agreement with the FDA.  

"We are very pleased with the FDA's continued willingness to work closely with the Company to identify the most expeditious regulatory pathway forward for ThermoDox® in HCC, a life threatening disorder," stated Mr. Michael H. Tardugno, Celsion's President and Chief Executive Officer.  "Our past consultation with the FDA regarding Chemistry Manufacturing and Controls (CMC) has permitted Celsion to implement and validate process improvements to its manufacturing methods used to produce ThermoDox at commercial scale."
