• Recent EU Clinical Trials: A multicentre, phase II, open label, single arm study of pixantrone in patients with CD20-positive relapsed or refractory aggressive non-Hodgkin lymphoma treated with rituximab, ifosfamide and etoposide.
• Uses: Pixantrone is an antineoplastic drug belonging to group of antitumor antibiotics. Pixantrone is an anlogue of Mitoxantrone (M373425) and is just as potent in the treatment of multiple sclerosis with f ewer toxic effects on cardiac tissue. Studies suggest that Pixantrone significantly reduces amyloid beta (A beta(1-42)) neurotoxicity, a mechanism implicated in Alzheimer's disease.
