TORONTO, ON and CHICAGO, IL, Aug. 11, 2014 /PRNewswire/ - Concordia Healthcare Corp. (“Concordia”) (TSX: CXR) (OTCQX: CHEHF), a diverse healthcare company focused on legacy pharmaceutical products, orphan drugs, and medical devices for the diabetic population, announced today that its subsidiary Pinnacle Biologics, Inc., a biopharmaceutical research and development company specializing in rare diseases, enrolled the first patients in a randomized Phase 2 trial to evaluate Photodynamic Therapy (PDT) with PHOTOFRIN® for patients with epithelioid malignant pleural mesothelioma (MPM).
Mesothelioma is a rare, aggressive and deadly cancer that most often manifests itself in the lining of the lungs and is caused almost exclusively by exposure to asbestos. The study is expected to enroll 102 patients over four years.
The study is being supported by an $8 million grant from the National Cancer Institute and conducted by researchers at the Perelman School of Medicine at the University of Pennsylvania in collaboration with the Roswell Park Cancer Institute.
Approximately 3,000 new cases of mesothelioma are diagnosed each year in the U.S.1; however numbers are expected to increase worldwide due to past uncontrolled exposures to asbestos2.
“Malignant pleural mesothelioma remains a complex and typically incurable disease that requires a multi-modal approach to treatment,” said Keith Cengel, MD, PhD, lead study investigator, Associate Professor and Director of Photodynamic Therapy in the Department of Radiation Oncology at the Perelman School of Medicine at the University of Pennsylvania. “To date, unprecedented survival rates have been achieved in these patients by combining surgery with Photofrin-mediated photodynamic therapy. Our current study looks to extend these observations by asking what component of this success is due to PDT and can we further improve our results in the future by understanding how PDT interacts with other cancer therapies. The outcome of this study has the potential to shift clinical treatment paradigms for mesothelioma and other cancers with high rates of local recurrence after surgery.”
PDT with PHOTOFRIN® is a two-step, targeted treatment that attacks tumor cells without permanently damaging surrounding tissue. The treatment involves the administration of PHOTOFRIN®, a nontoxic, photosensitizing agent that accumulates in cancer cells followed by the application of laser light to the tumor, which activates the drug and attacks the tumor. In this study, PHOTOFRIN® will be administered to trial participants 24 hours prior to surgery. Patients will then undergo a radical pleurectomy, the removal of the pleura or lining of the lung along with the tumor cells contained within. They will then be randomized to two arms: half will receive PDT intraoperatively via an intense laser inserted in the chest cavity during the surgery, along with post-operative standard chemotherapy; and half will receive only post-operative chemotherapy. PHOTOFRIN® absorbs the light from the laser and produces an active form of oxygen that can attack residual microscopic cancer cells left behind after surgery. Radical pleurectomy may allow mesothelioma patients to keep their lung and may provide better postoperative quality of life and improved survival rates when compared to other common definitive mesothelioma surgeries.
“This trial evaluating the efficacy of PDT therapy with PHOTOFRIN® in mesothelioma will hopefully lead to greater understanding and insight into a rare and deadly form of cancer and hopefully establish a new treatment path for patients for whom few options exist,” said Mark Thompson, chief executive officer of Concordia Healthcare Corp.
This work is funded by NIH/NCI grant # P01 087971-11.
About PHOTOFRIN®
PHOTOFRIN® is indicated for the treatment of esophageal cancer, non-small-cell lung cancer and high-grade dysplasia in Barrett’s esophagus. PHOTOFRIN® was granted orphan drug designation (ODD) by the FDA in 2004 for cholangiocarcinoma (CCA), a rare cancer in the bile ducts that carry bile from the liver to the small intestine, and in December 2011, the FDA granted a second ODD for PHOTOFRIN® as adjuvant therapy to surgery for the treatment of malignant pleural mesothelioma.
