T-Cell Lymphoma Patients Achieve Long Lasting Responses With Genmab's HuMax-CD4
Copenhagen, Denmark (ots/PRNewswire)
Genmab A/S (CSE: GEN) announced today that cutaneous T-cell lymphoma (CTCL) patients in the HuMax-CD4 Phase II studies achieved long lasting responses, with an average response duration of more than 6.6 months. This duration of response data is based on an analysis of responding mycosis fungoides (MF) patients at all dose levels, 280, 560 and 980 mg.
In addition, median time to disease progression of all 38 MF patients in the two Phase II studies is more than 5.7 months. Disease progression is defined as an increase in disease that is more than 25% above the baseline measurement taken when patients entered the study.
The average duration of response for the high dose patients, who received either 560 mg or 980 mg, is also more than 6.6 months. In addition, median time to progression is more than 5.7 months. The median event time has not yet been reached for the high dose patients for either measure as more than half the responding patients maintain their responses and more than half of the high dose patients have not experienced disease progression. Genmab will continue to follow these patients.
Six of seven patients who achieved a response at the 560 mg dose continue to maintain those responses as of the analysis date. These were early stage patients and generally less heavily pre-treated than the patients who received the 980 mg dose.
Advanced stage patients, who received either 280 or 980 mg, obtained a median response duration of 5.3 months and median time to progression of 4.8 months.
Data for duration of response and time to disease progression have been calculated as of the end of August, 2004.
These data are being presented at the "Fourth International Congress on Monoclonal Antibodies in Cancer" in Colorado Springs, Colorado by Dr. Jan van de Winkel, Genmab's Chief Scientific Officer.
Dr. van de Winkel is also presenting data about the amount of HuMax-CD4 that was found in patients' bloodstream (serum concentration) during the study. In these studies, high serum concentration of HuMax-CD4 appeared to increase the likelihood of a clinical response.
"I believe the length of the Phase II responses is a positive sign, especially as the product has been well tolerated in clinical studies to date," said Lisa N. Drakeman, Ph.D., Chief Executive Officer of Genmab. "Furthermore, we are encouraged that so many early stage patients who received the 560 mg dose all seem to be maintaining their responses. This Phase II data shows the potential to provide a benefit to patients at a variety of disease stages."
About HuMax-CD4
HuMax-CD4 is a high affinity human antibody that targets the CD4 receptor on T-lymphocytes. Genmab has run two Phase II studies using HuMax-CD4 to treat CTCL, one in early stage patients and the other for patients with advanced disease, both of which achieved positive results. Thirty-eight CTCL patients with MF, the most common form of CTCL, were treated in these studies. Genmab has a US Orphan Drug designation for HuMax-CD4 to treat MF patients and is making plans for a pivotal study with HuMax-CD4 under an FDA Fast Track Designation for patients who have failed available therapies.
