Data from a Phase 1/2 trial suggest a potential associationnbetween higher doses of MDX-060 and improvement in disease control and prolonged progression-free survival in patientsn with relapsed or refractory CD30- positive lymphomas
PRINCETON, NJ, USA | April 16, 2008 | Medarex, Inc. announced today data from a Phase 1/2 trial that suggest a potential association between higher doses of MDX-060, an investigational anti-CD30 antibody, and improvement in disease control and prolonged progression-free survival in patients
with relapsed or refractory CD30- positive lymphomas. Results from the Phase 1/2 trial were presented at the Annual Meeting of the American Association for Cancer Research (AACR), being held April 12-16, 2008 in San Diego (Abstract #5525).
"We continue to assess the potential for anti-CD30 antibody therapies in the marketplace and are pleased with the findings of this exploratory study," said Howard H. Pien, President and CEO of Medarex. "We look forward to analyzing these results alongside the Phase 2 proof-of-concept chemotherapy combination data that is expected later in the year."
In the completed dose-escalation Phase 1/2 trial, 72 patients with relapsed or refractory CD30-positive lymphoma received weekly doses of MDX-060 (0.1, 1, 4, 10 or 15 mg/kg) for four weeks. Of the 33 patients treated at the two highest doses of MDX-060, disease control was observed in 51 percent of patients (3 complete responses, 14 stable disease), with median progression- free survival of 3.7 months and 39 percent of patients with no evidence of disease progression four months post-treatment. Of the 39 patients treated at the three lowest doses of MDX-060, disease control was observed in 33 percent of patients (1 complete response, 2 partial responses, 10 stable disease), with median progression-free survival of less than 2 months and 18 percent of patients with no evidence of disease progression four months post-treatment. MDX-060 treatment was well-tolerated with no clinically meaningful infusion reactions. The most frequently reported drug-related adverse events were fatigue and pyrexia considered to be mild to moderate in severity.
About Anti-CD30 Antibody Therapy
MDX-060 is a fully human antibody that targets CD30, a marker found on activated lymphocytes that is present on malignant cells of Hodgkin’s disease (HD) as well as other CD30-expressing cancers. Medarex is currently conducting an ongoing Phase 2 proof-of-concept trial of MDX-060 in combination with gemcitabine for HD. Medarex is also developing MDX-1401, a second-generation non-fucosylated version of the MDX-060 parental antibody, that is enhanced for greater antibody-dependent cellular cytotoxicity and is being explored in a multi-dose, dose-escalation Phase 1 clinical trial for HD.
About Medarex
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. More than 40 of these therapeutic product candidates derived from Medarex technology are in human clinical testing or have had INDs submitted for such trials, with seven of the most advanced product candidates currently in Phase 3 clinical trials or the subject of regulatory applications for marketing authorization. Medarex is committed to building value by developing a diverse pipeline of antibody products to address the world’s unmet healthcare needs.
