| Research Abstract |
The purpose of this study was to reduce the side effects and the pain caused by frequent injections of IFN-beta for melanoma while specifically targeting the lymph nodes by taking advantage of metal coordination to bind IFN-beta to hyaluronic acid. Sustained release of IFN-beta by conjugation with HA prolongs lymphatic retention. IFN-beta-hyaluronic acid conjugates can be given as an adjuvant therapy post-surgery to reduce the risk of recurrence and eradicate melanoma residuals, such as micrometastases. In addition, due to the sustained release characteristics of the conjugate, weekly injections for melanoma could replace conventional daily injections, thereby reducing pain as well as healthcare costs.
