Researchers bring oral cancer-fighting patch to patients

Source: medicalxpress.com Author: staff The Ohio State University and the University of Michigan have signed an exclusive worldwide agreement with Ohio-based Venture Therapeutics, Inc, to form a new company to develop and commercialize a pharmaceutical technology targeted for the treatment of precancerous oral lesions. These lesions are currently managed by invasive surgery and approximately a third of these lesions will reoccur after surgery. Previously published data shows that about 30 percent of the higher grade precancerous oral lesions progress to oral cancer, specifically oral squamous cell carcinoma. This type of cancer is particularly devastating to patients because treatment entails removal of facial and mouth structures essential for esthetics and function. The National Cancer Institute estimates that 42,440 Americans will be diagnosed with oral cancer and over 8,390 oral cancer related deaths will occur in 2014. The pharmaceutical technology developed by researchers at The Ohio State University (OSU) College of Dentistry with secondary appointments at the OSU Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James) and the University of Michigan addresses a significant unmet need related to the prevention of oral cancer. Precancerous oral lesions can be seen and touched by patients, so this easy access to the lesion allows the use of local delivery formulations in an oral patch to directly treat the disease without causing adverse side effects. "This type of collaboration, involving multiple university partners with strong industry support, is increasingly essential to expedite the discovery, development and [...]

Medicated patch shows promise in oral cancer prevention

Source: www.healthnewsdigest.com Author: press release Researchers at The Ohio State University Comprehensive Cancer Center have developed a medicated oral patch that allows a chemoprevention drug to release directly into precancerous lesions in the mouth over an extended time. The study evaluated the drug fenretinide, a synthetic derivative of vitamin A that has highly promising anti-cancer properties. Until now, scientists have failed to achieve a therapeutic, systemic dose of fenretinide because of drug toxicity and rapid release from the body. By using a new mucoadhesive patch invented by a team from Ohio State’s Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC-James) and the University of Michigan, the researchers developed a delivery system that can provide continuous drug therapy to saliva-coated oral tissue. “The challenge with oral gels or rinses is the medication can dissolve in saliva before it penetrates into the tissue. This patch allows us to target and control drug delivery and tissue exposure,” says Dr. Susan Mallery, an oral pathologist at Ohio State’s Comprehensive Cancer Center. The patch consists of three layers: a disk saturated with fenretinide and polymers to make the drug more soluble in saliva, an adhesive ring to hold the disk in place, and a backing layer to ensure the medication stays within the patch. In their study recently published online by the journal Pharmaceutical Research, Mallery and co-investigator, Dr. Peter Larsen of Ohio State, tested the fenretinide patch using simulated saliva as well as lab animals. In [...]
