Decision Resources, Inc., one of the world's leading research and advisory firms focusing on pharmaceutical and health care issues, finds that a variety of barriers may hinder the sales of radioimmunotherapies in the aggressive non-Hodgkin's lymphoma drug market.

"Companies investigating radioimmunotherapies to treat aggressive non- Hodgkin's lymphoma -- such as Corixa/GlaxoSmithKline and Biogen Idec -- will continue to struggle to overcome multiple barriers to uptake, including coordination difficulties between oncologists and the nuclear medicine physicists who will administer these therapies; regulatory and reimbursement challenges; and, certainly most significant in the United States, referral disincentives for office-based oncologists," said Mary Fletcher-Louis, analyst at Decision Resources.

According to the new Pharmacor study entitled Non-Hodgkin's Lymphoma, results of a forthcoming head-to-head trial between two radioimmunotherapies, 90Y-ibritumomab and 131I-tositumomab, in the indolent non-Hodgkin's lymphoma setting and sponsored by Corixa/GlaxoSmithKline, will be the principal determinant of market share distribution between the two agents.

About Non-Hodgkin's Lymphoma

Non-Hodgkin's lymphomas constitute the fifth most common cancer in the United States. In terms of pharmaceutical sales, non-Hodgkin's lymphoma ranks fourth after breast cancer, non-small-cell lung cancer, and colorectal cancer. Approximately 40% of non-Hodgkin's lymphomas follow an indolent course; the remaining non-Hodgkin's lymphomas are aggressive tumors.
