Problems solved by technology

While such agents have potential for use as new cancer therapeutics, it is believed that many signaling inhibitors act in a cytostatic rather than cytotoxic manner by blocking cellular progression through the cell cycle
They differ from conventional cancer chemotherapy drugs by being slightly toxic but also having weaker antitumor activity
[0007] Therefore, challenges remain in delivering new and improved cancer treatments

Abstract

Methods are provided for treating cancer, comprising administering (1) a farnesyl protein transferase inhibitor in conjunction with (2) an additional Ras signaling pathway inhibitor to induce cancer cell death and tumor regression.

Description

field of invention [0001] The present invention describes new methods of treating individuals with cancer, including neoplastic and metastatic disease. In particular, the present invention provides methods of treating cancer comprising the combined use of (1) a farnesyl protein transferase ("FPT") inhibitor and (2) other Ras signaling pathway inhibitors to induce a synergistic level of cancer cell death ( especially apoptosis), thereby enabling the use of low-dose regimens. Background of the invention [0002] Figure 1 of this specification is a simplified linear depiction of the signal transduction pathways leading to cell proliferation. This pathway is referred to herein as the "Ras signaling pathway" because Ras is the key transmitter in the pathway, receiving signals from upstream elements (eg, growth factor receptors) and transmitting them to downstream elements. [0003] The signaling pathways initiated by growth factor receptors that lead to cell p...
