STAMFORD, CT, USA | Mar 01, 2006 | Delcath Systems, Inc. (NASDAQ: DCTH), today announced that the first patient has been treated with the Delcath System in its pivotal Phase III clinical trial for the treatment of metastatic melanoma in the liver using the Delcath system with melphalan, an approved anticancer agent at the National Cancer Institute (NCI).
The NCI is the first site to enroll patients in the Phase III trial with melphalan. As of February 28, two patients were enrolled and started on therapy. In accordance with the company’s Special Protocol Assessment and Agreement (SPA) with the U.S. Food and Drug Administration (FDA), announced February 22, 2006, the multi-center trial requires the enrollment of 92 total patients to determine whether patients using the Delcath system experience a reduction in tumor burden or zero progression of the tumor for a longer period of time than those receiving best alternative care. Patients randomized to the control group whose tumors progress will be allowed to cross over and receive treatment using the Delcath system without impacting the study.
“We believe the trial’s positive start can be attributed to the establishment of a protocol the investigators wanted,” said M.S. Koly, president and chief executive officer of Delcath. “While the trial needs to be randomized to provide a statistically valid result, the FDA has agreed to allow control arm patients to receive the best alternative care. This removes one of the primary objections of potential investigators to our previous trial, where the use of a specific systemic therapy may not be the best for the patient randomized to the control arm.”
“A more important attribute of the randomized trial is the FDA’s agreement to accept progression free survival as the primary endpoint. Progression free survival is the length of time a patient is both alive and free from any significant increase in the tumor (free from progression). Control patients whose tumors grow will have completed their portion of the trial and at the principal investigator’s judgment will then be permitted to receive the Delcath treatment. The investigators feel the availability of crossover will greatly speed patient accrual in this study,” explains Mr. Koly.
“Delcath’s goal all along has been to bring our system to market as quickly and safely as possible. We are convinced that the Delcath system is among the best methods to help many liver cancer patients achieve a significantly better quality of life while dealing with their disease. The SPA agreement with the FDA has allowed us to aggressively proceed down the fast track path and we believe that the enrollment of patients will move quickly, and that the results will convince the FDA of the efficacy of our product,” said Mr. Koly. “In addition to the NCI, we are lining up other top cancer centers to join our trial and accelerate patient accrual as we leverage our strong relationships within the medical community, including Dr. Richard Alexander, the recently appointed Associate Chairman of Clinical Research at the University of Maryland School of Medicine in Baltimore.”
“While we are excited about commencing the trial, we must follow the NCI’s clinical trial guidelines and will not be able to release material information regarding the Phase III trial while it is underway unless investigators publish or present their experiences,” Koly concluded.
The Delcath system delivers high-dose chemotherapy directly to the liver via the hepatic artery. As blood exits the liver, special Delcath filters trap the chemotherapy, protecting the rest of the body from excessive toxicity. The procedure is repeatable and is less invasive than traditional surgical ways of performing isolated perfusion to effect dose-directed therapy for specific body organs or regions.
About Special Protocol Assessment and Agreement (SPA)
An SPA is a written agreement from the FDA that the Phase III trial protocol design, clinical endpoints, and statistical analyses are acceptable to support regulatory approval, and can only be granted prior to initiation of the clinical trial. An SPA is binding upon the FDA unless a substantial scientific issue essential to determining safety or efficacy is identified after testing has begun.
