Trimodal Chemoprevention via Controlled Release Polymeric Implants
TS-037740 — Biodegradable polymeric implants for local delivery of therapeutic agents to cancer sites as an alternative to traditional radiation or chemotherapy treatments.
While surgery remains the gold standard of primary treatment for solid tumors, such as oral squamous cell carcinoma (OSCC), adjunct therapies (i.e. radiation or chemotherapy) are commonly used for patients with advanced stage or non-resectable/recurrent cancers. However, both radiation and traditi…
While surgery remains the gold standard of primary treatment for solid tumors, such as oral squamous cell carcinoma (OSCC), adjunct therapies (i.e. radiation or chemotherapy) are commonly used for patients with advanced stage or non-resectable/recurrent cancers. However, both radiation and traditional chemotherapy elicit significant toxic systemic side effects. In contrast, local delivery formulations provide treatment-appropriate drug levels at the target site while avoiding systemic side effects.
Researchers at The Ohio State University, led by Dr. Susan Mallery, developed locally injectable pharmaceuticals comprising of biodegradable polymer formulations combined with therapeutic agents that can be used to provide a controlled release of therapeutically-relevant levels of cancer preventing agents directly to the treatment site. The polymeric carrier, a forming gel or millicylinder implants, is determined by the desired length of drug release. In addition, an anti-interleukin 6 agent and a therapeutic agent selected from a synthetic vitamin A analogue or metabolite, an estradiol metabolite, or a combination thereof is included for treatment. The initial focus of the invention was for OSCC, but the therapeutic could potentially be applied in other tissue or organ based cancers, such as those originating from the breast or prostate.
