Proteasome Inhibitors for Cancer Therapy


Pancreatic cancer - this disease progresses very rapidly, and is invariably fatal. The mean survival time after diagnosis is 3 to 6 months. A small Phase I pilot study using proteasome inhibitor appears very promising. A combination of bortezomib with gemcitabin resulted in a significantly increased survival time.

Prostate cancer - This cancer is relatively easy to cure while it is confined to the prostate gland. However, after it has spread, treatment with chemotherapy has proven difficult, and treatment to block male hormone secretion is only partially effective. A Phase I study treating advanced prostate cancer patients with a combination of bortezomib and docetaxel gave promising results.

Colon and esophageal cancers - preliminary Phase I clinical trials indicated that many patients showed stability of their cancers and clinical responses.
