AEZS-108 : a targeted cytotoxic analog of LHRH for the treatment of cancers positive for LHRH receptors.
AEZS-108 is a cytotoxic analog designed for receptor-mediated targeted chemotherapy and consists of an LHRH carrier linked to doxorubicin. Preclinical studies demonstrate that the uptake of AEZS-108 is achieved by receptor-mediated endocytosis. Results of Phase I and II clinical trials in patients with gynecological cancers demonstrated anticancer activity without cardiotoxicity even in highly pretreated patients. Phase I/II studies in castration-resistant prostate cancer and chemotherapy refractory bladder cancer are in progress. Targeted chemotherapy with a cytotoxic analog of LHRH, such as AEZS-108, is therefore being considered for Phase III studies in advanced endometrial cancers positive for LHRH receptor. LHRH receptors are also present in human colon cancers, melanomas, lymphomas, and sarcomas, and treatment of these cancers with AEZS-108 should also be undertaken. Before such treatment with AEZS-108 is begun, the status of tumoral LHRH receptors of patients must be determined.
