Medarex Announces Allowance of Investigational New Drug Application for Company’s First Antibody-Drug Conjugate, MDX-1203
“Antibody-drug conjugates are another important and innovative therapeutic approach used to fight cancer by effectively and selectively killing tumor cells over-expressing specific tumor antigens, so we are extremely excited in achieving the IND filing for MDX-1203, the first candidate from our proprietary ADC technology platform,” said
An open-label, multi-dose, dose-escalation Phase 1 clinical trial will be conducted in patients with RCC and NHL. This trial is designed to establish and evaluate the safety, tolerability and maximum tolerated dose, as well as preliminary distribution, metabolism and pharmacokinetics of MDX-1203.
About Medarex’s Antibody-Drug Conjugate (ADC) Technology
Medarex has enhanced its core UltiMAb(R) antibody platform with a suite of technologies that optimize or augment the therapeutic activity of antibodies, and one important technology expansion is the company’s proprietary Antibody-Drug Conjugate platform. Medarex’s proprietary ADC technology uses a cytotoxic agent that is a potent, synthetically manufactured prodrug (a DNA minor-groove binding alkylating agent) which is attached to an antibody using a stable peptide-based linker. Medarex believes that its ADC technology overcomes many of the key development challenges of drug conjugates, including issues of linker stability, potency and multi-drug resistance while maintaining a wide therapeutic window with minimal toxicity.
Medarex has conducted multiple preclinical studies on several investigational antibody-drug conjugate candidates in development demonstrating enhanced anti-tumor activity in xenograft models, even with single doses as low as 0.005 micro mol/kg, when compared to the anti-cancer antibodies alone. Preclinical studies have also demonstrated that anti-tumor activity is maintained in drug-resistant cancer cells. Additionally, Medarex’s activatable prodrug has been shown to accumulate in the targeted tumor cells but not in normal tissue cells, thereby minimizing the toxicity profile but not the anti-tumor activity in animal and primate models.
Medarex is a biopharmaceutical company focused on the discovery, development and potential commercialization of fully human antibody-based therapeutics to treat life-threatening and debilitating diseases, including cancer, inflammation, autoimmune disorders and infectious diseases. Medarex applies its UltiMAb(R) technology and product development and clinical manufacturing experience to generate, support and potentially commercialize a broad range of fully human antibody product candidates for itself and its partners. Over forty of these therapeutic product candidates derived from Medarex technology are in human clinical testing or have had INDs submitted for such trials, with the most advanced product candidates currently in Phase 3 clinical trials, the subject of regulatory applications for marketing authorization or approved in
