Overview of 11 peer review publications presented in 'Future Oncology'
SEATTLE, June 8 /PRNewswire-FirstCall/ -- Cell Therapeutics, Inc. (CTI) (Nasdaq and MTA: CTIC) reports a summary of peer reviewed publications spanning preclinical, Phase I and Phase II clinical studies with pixantrone was reviewed in the May 2009 edition of Future Oncology (Volume 5, Issue 4) which is now available on line. The article, "Pixantrone: a promising drug in the treatment of non-Hodgkin lymphomas," was written by Drs. Barry W. Hancock and Loaie M. El-Helw of the Weston Park Hospital, Sheffield UK.
The review focuses on the impressive preclinical anti-tumor activity demonstrated in hematologic cancers over standard anthracyclines and the rational design modifications to the chemical compound believed to be responsible for enhanced DNA damage and binding to topoisomerase II enzyme, a key target for anthracycline mediated tumor death. These modifications are also hypothesized by the authors to underlie the drugs' low cardiotoxicity profile in preclinical animal studies when compared to standard anthracycline drugs.
Five phase I/II studies in which pixantrone was added to standard chemotherapy regimens for treating relapsed aggressive and indolent NHL were also reviewed in the article. Pixantrone, when added to standard multi-agent chemotherapy regimens produced encouragingly high rates of overall response (58-74%) including high rates of complete responses (37-57%). As previously reported, neutropenia was the dose limiting toxicity when used as a single agent.
"In both preclinical and early clinical studies pixantrone exhibited lower cardiac toxicity and better anti-tumor activity than that observed with alternative anthracyclines, as it is devoid of the putative cardiac toxicity generating chemical structure," said Barry W. Hancock, M.D., Professor of Medical Oncology, Weston Park Hospital, Shefield.
Pixantrone (BBR 2778), is a novel major groove binder with an aza-anthracenedione molecular structure that differentiates it from the anthracyclines and other related chemotherapy agents. Anthracyclines are the cornerstone therapeutic for the treatment of lymphoma, leukemia, and breast cancer. Although they are sufficiently effective to be used as first-line (initial) treatment, they cause cumulative heart damage that may result in congestive heart failure many years later. As a result, there is a lifetime limit of anthracycline doses and most patients who previously have been treated with an anthracycline are not able to receive further anthracycline treatment if their disease returns. It also can be administered through a peripheral vein rather than a central implanted catheter as required for other drugs in this class.
