What is Sutent?


Sutent (sunitinib), is a targeted anti-cancer treatment for
patients with gastrointestinal stromal tumors (GIST), a rare
stomach cancer, and advanced kidney cancer.

Sutent (a tyrosine kinase inhibitor) was approved for the
treatment of patients with gastrointestinal stromal tumors
(GIST) whose disease has progressed or who are unable to
tolerate treatment with Gleevec(imatinib mesylate), the
current treatment for GIST patients.

FDA also granted accelerated approval for Sutent in the
treatment of patients with advanced renal cell carcinoma
(RCC).

In contrast to the approval for GIST, which was based on the
drug's ability to delay the growth of the tumors, this approval
was based on Sutent's ability to reduce the size of the tumors
in patients

Sunitinib “adds about six months of additional freedom from
progressing disease” to the two years that many patients
achieve from first-line treatment with imatinib"  said Casali
during his presentation at the ASCO annual meeting.

"Sunitinib may work when imatinib is not effective because
sunitinib targets more than one cancer cell molecular
pathway and can block the action of several kinase
enzymes,” explains Barry Anderson, M.D., Ph.D., of the
National Cancer Institute’s Cancer Therapy Evaluation
Program.

“The work is exciting," he adds, "because we are learning
about the importance of particular cancer cell molecular
pathways and new strategies for striking at important
molecular targets may develop from such clinical trial data
that could extend such therapies to first-line treatment in
other types of cancers."
