About Pixantrone
Pixantrone (BBR 2778) is an investigational agent under development for the potential treatment of various hematological malignancies, solid tumors and immunological disorders. It was developed to improve the activity and safety of the anthracycline family of anti-cancer agents. Anthracyclines have been shown to be very active clinically in a number of tumor types. However, they are usually associated with cumulative heart damage that prevents them from being used in a large proportion of patients. Pixantrone has been designed to reduce the potential for these severe cardiotoxicities, as well as to potentially increase activity and simplify administration compared to currently marketed anthracyclines.
About XYOTAX(TM)
XYOTAX(TM) (paclitaxel poliglumex, CT-2103) is a biologically enhanced
chemotherapeutic that links paclitaxel, the active ingredient in Taxol(R),
to a biodegradable polyglutamate polymer, which results in a new chemical
entity. When bound to the polymer, the chemotherapy is rendered inactive,
potentially sparing normal tissue's exposure to high levels of unbound,
active chemotherapy and its associated toxicities. Blood vessels in tumor
tissue, unlike blood vessels in normal tissue, are porous to molecules like
polyglutamate. Based on preclinical studies, it appears that XYOTAX is
preferentially distributed to tumors due to their leaky blood vessels and
trapped in the tumor bed allowing significantly more of the dose of
chemotherapy to localize in the tumor than with standard paclitaxel. Once
inside the tumor cell, enzymes metabolize the pr
