The SPA provides agreement that the Phase 3 trial design adequately addresses objectives that, if met, would support the submission for regulatory approval of Melphalan/HDS.

The agreement also represents the satisfactory resolution of a substantial number of the FDA’s issues in the Complete Response Letter (CRL) issued in September 2013. These issues were related to safety of a previous generation of the Melphalan/HDS device and procedure. Delcath completed the work necessary to satisfy these requirements prior to submitting its request for the SPA agreement.

The new pivotal trial, the FOCUS Clinical Trial for Patients with Hepatic Dominant Ocular Melanoma (the FOCUS trial), will evaluate the safety and efficacy profile of the Melphalan/HDS versus best alternative care.

The primary endpoint will be overall survival, and secondary endpoints will include progression-free survival, overall response rate and quality-of-life measures.

"This agreement marks a major milestone for Delcath," said Jennifer K. Simpson, Ph.D., MSN, CRNP, President and Chief Executive Officer of Delcath.

"Under this SPA our new FOCUS trial, if successful, will provide a clear pathway to an indication in hepatic dominant ocular melanoma for Melphalan/HDS. Additionally, through the dedicated work of our team and in close collaboration with the FDA, we have satisfied a substantial number of the requirements of the FDA’s 2013 CRL.

"Based on our commercial experience in Europe, the continued support and enthusiasm from Key Opinion Leaders and the clinical data that have been presented and published recently, we have confidence that our FOCUS trial can demonstrate the efficacy and safety necessary for a positive benefit/risk profile for Melphalan/HDS, and that the study’s objectives can be met. There is strong interest from leading cancer centers in the U.S. and Europe to participate in this study and we look forward to beginning enrollment in this registrational trial."
