Akt and a number of other key signal
transduction pathways, including the JNK and MAPK pathways, all of which
are pathways associated with programmed cell death, cell growth, cell
differentiation and cell survival. The effects of perifosine on Akt are of
particular interest because of the importance of this pathway in the
development of most cancers, the evidence that it is often activated in
tumors that are resistant to other forms of anticancer therapy, and the
difficulty encountered thus far in the discovery of drugs that will inhibit
this pathway without causing excessive toxicity. High levels of activated
Akt (pAkt) are seen frequently in many types of cancer and have been
correlated with poor prognosis in patients with soft-tissue sarcoma,
gastric, hepatocellular, endometrial, prostate, renal cell, head and neck
cancers and hematological malignancies, as well as glioblastoma. The
majority of tumors expressing high levels of pAkt were high-grade, advanced
stage or had other features associated with poor prognosis. High pAkt is
often seen in tumors that are resistant to conventional cancer treatments,
including radiotherapy, chemotherapy, endocrine therapy, and especially
therapy with some of the newer biologicals.
To date, over 1,700 patients have been treated with KRX-0401 in trials
conducted both in the United States and Europe. Its safety profile is
distinctly different from that of most cytotoxic agents. It does not appear
to cause myelosuppression (depression of the immune system that may lead to
life threatening infections), thrombocytopenia (a decrease in platelets
that may result in bleeding), skin rash, flu-like symptoms or alopecia
(hair loss); all of these toxicities occur frequently with many of the
currently available treatments for cancer. The main side effects of
perifosine are nausea, vomiting, diarrhea and fatigue, but these are either
mild or non-existent in lower doses that have induced tumor regression.
